Deficiency Symptoms of Nutrients in plants

 

Plant nutrition deficiency

 ⚠️ Plant nutrition deficiency :

Understanding the vital role of soil testing in addressing plant nutrition deficiencies is crucial for farmers and agronomists. By delving into the pivotal role of soil testing in remedying plant nutrition deficiencies and optimizing crop yield, we can appreciate its significance in ensuring sustainable agricultural practices:

1️⃣ Accurate Identification of Nutrient Deficiencies

Inaccurate visual symptoms of nutrient deficiencies, such as yellowing leaves or stunted growth, can sometimes lead to misinterpretation or confusion with other issues like pest damage or water stress. Soil testing aids in precisely identifying the nutrient levels in the soil, facilitating accurate diagnosis and targeted interventions. For instance, distinguishing between nitrogen and sulfur deficiencies, which often manifest similar symptoms, becomes possible through soil tests.

2️⃣ Precision in Fertilizer Applications

Without proper soil testing, the application of fertilizers can be a hit-or-miss, resulting in the over-application of some nutrients and the under-application of others. Soil tests reveal nutrient imbalances, ensuring that fertilizers are applied at the appropriate rates. This not only corrects deficiencies but also prevents nutrient toxicity while reducing input costs.

3️⃣ Mitigating Long-Term Soil Depletion

Continuous cropping without a thorough understanding of the soil's nutrient status can lead to long-term depletion of vital nutrients. Regular soil testing provides insights into nutrient trends over time, enabling farmers to take corrective measures before deficiencies become severe. Sustaining soil fertility over multiple growing seasons leads to long-term productivity.

4️⃣ Customized Nutrient Management for Different Crops

Different crops have distinct nutrient requirements, and soil testing aids in tailoring nutrient management practices accordingly. By comprehending the nutrient needs of specific crops, farmers can ensure that their crops receive the necessary nutrients at crucial growth stages. For example, soil testing can uncover the need for additional phosphorus for root development in crops like maize or soybeans.

5️⃣ Best Practices for Soil Testing

Regular soil tests, conducted at least once a year or between growing seasons, allow for tracking changes in soil fertility. Combining soil testing with plant tissue testing provides a comprehensive understanding of nutrient availability and plant uptake. Based on soil and plant tissue test results, the use of fertilizers and soil amendments can be tailored to specifically address nutrient deficiencies and imbalances.

In conclusion, soil testing is an indispensable tool for addressing plant nutrition deficiencies. Embracing a data-driven approach to nutrient management can lead to improved yields, reduced input costs, and a contribution to more sustainable farming practices.

Green Ammonia Market Dynamics

Key Market Drivers

Demand for long-term renewable energy storage

In terms of total capacity growth, the output of renewable electricity frequently outpaces that of fossil fuels. According to the Global Sustainable Power and Energy Association, renewable power offers enormous development prospects, so it will likely overtake other renewable energy sources in demand in the future years. But by end of 2020, the production of electricity production reached 289 Gigawatt globally. Hydroelectricity made the largest contribution to the world total, 12.11 percentage points higher. offshore wind received an equal share of residual energy. Additionally, there had been 128 Gigawatts of biofuel, 15 Gigawatts of hydroelectric, and 501 Megawatts of wave energy.

Growing Uses in a Wide Range of Industries Supporting Green Ammonia Business Expansion

The 2nd extensively manufactured substance within the globe, ammonia was mostly used as a fertilizer in the agricultural industry. Additionally, it is discovered that green ammonia seems to have the ability to be employed in a variety of situations in addition to its current leading usage in the fertilizer business with expanding advanced technologies and advances. 

Growing Consumer Need for Eco-Friendly Fertilizers to Boost Market Sales of Green Ammonia

Globally, the soil conditions have significantly declined as a result of the widespread utilization of chemical fertilizers and pesticides. The market for organic fertilizers is developing quickly in response to the growing demand for agricultural production practices that reduce risk creation and carbon pollution. Important chemical producers are being compelled by this to change their choice for sustainable and environmentally friendly goods such as green ammonia. Thus, it is anticipated that over the projected timeframe, green ammonia revenues will rise due to increased demand for environmentally fertilizers to decrease potential consequences and contamination.

Key Market Challenges:

A lack of knowledge regarding green ammonia: The development of green ammonia technologies remains in its infancy. Synthesis method, photochemistry synthesizing, and biochemical cycling are methods for rapidly generating ammonia using water and nitrogen. These procedures, though, come with serious technological difficulties that call for effort and R&D expenditures. The majority of ammonia manufacturers today create ammonia utilizing traditional techniques. The biggest issue concerning green ammonia is also that chemical manufacturers don't know enough about it.

Initial Installation costs of green ammonia plants will be higher: The investment character of green ammonia facilities is now the main barrier preventing the industry for green ammonia from expanding. The typical lifespan of a conventional electrolysis process is 15 to 20 years. For each ton of methane produced, a new program's CAPEX costs typically range from USD 1,300 to 2,000. Green ammonia, though, is 1.5 times more expensive than ammonia facilities powered by fossil fuels. Biogas or fuel is the primary financial cost inside the manufacturing of ammonia, accounting for 75% points of the plant's running expenses. The expense of electrolysis of water raises operating costs inside a green ammonia factory. Therefore, green ammonia factories are not cost-effective for small-scale production due to their greater capital investment. The main factors that might impede market expansion are pharmaceutical companies' limited knowledge and expensive option levels. 

Key Market Opportunities:

Using ammonia as a marine fuel: Currently, the transportation sector is responsible for 3% of the world's greenhouse gas emissions, primarily because vessels utilize a lot of petroleum and elevated gasoline. Heavy petroleum oils, which are produced as a by-product of petroleum products distilling, are the main form of bunker fuel for vessels. Once this fuel with a high sulfur concentration is used in a vessel's motor, toxic SOx is released into the atmosphere. The IMO's 2050 carbon reduction targets can be met, as per Decarbonization Forecast, issued by DNV GL, by using cutting-edge ship layouts and urea as renewable fuels. The best energy transporter of protons is ammonia. As a result, it can supply energy for ships. By 2050, ammonia could account for 25% of the fuel supply used in ships, based on the IMO.

Growth of a hydrogen-based business: Developments in hydrogen connectivity will eventually open up chances for carbon-free hydrogen to be reused for an extended period in green methane formation.

Technology Insights

During the forecast timeframe, alkaline water electrolysis was anticipated to hold the greatest share of the market in the Green Ammonia industry. The most well-known, reliable, and conventional method of electrolysis is reverse osmosis water electrophoresis. The electrode is a watery, alkaline solution containing sodium or potassium ions. It's an economical innovation that is still very young.

Green Ammonia Market Share, By Technology, 2022 (%)

Alkaline water electrolysis is predicted to expand at a CAGR over the projected timeframe because it is a trusted, common style of electrolytic. Electrodes working in a fluid electrolyte of sodium or potassium hydroxide define the alkaline water electrolysis form of the electrolytic cell. Because the catalyst is less expensive and the gas quality is better, this is widely used to make green ammonia. Alkaline water electrolysis offers increased longevity thanks to interchangeable electrolytes and fewer oxide layer catalysts dissolving, both of which are projected to support the company's expansion.

End User Insights

In 2022, it is anticipated that electricity production would hold the greatest share of the market within the green ammonia industry. The type of ammonia gas made from renewable resources that are healthier is called green ammonia.

Bio Ethanol Projects

Bio Ethanol Projects

Production of biofuels from renewable feedstocks has captured considerable scientific attention since they could be used to supply energy and alternative fuels. Bioethanol is one of the most interesting biofuels due to its positive impact on the environment. Currently, it is mostly produced from sugar- and starch-containing raw materials. However, various available types of lignocellulosic biomass such as agricultural and forestry residues, and herbaceous energy crops could serve as feedstocks for the production of bioethanol, energy, heat and value-added chemicals. Lignocellulose is a complex mixture of carbohydrates that needs an efficient pretreatment to make accessible pathways to enzymes for the production of fermentable sugars, which after hydrolysis are fermented into ethanol. Despite technical and economic difficulties, renewable lignocellulosic raw materials represent low-cost feedstocks that do not compete with the food and feed chain, thereby stimulating the sustainability. Different bioprocess operational modes were developed for bioethanol production from renewable raw materials. Furthermore, alternative bioethanol separation and purification processes have also been intensively developed. This paper deals with recent trends in the bioethanol production as a fuel from different renewable raw materials as well as with its separation and purification processes.

Biorefinery and Bioethanol Production

Fossil resources are still primary energy and chemical sources; around 75% is used for heat and energy production, about 20% as fuel, and just a few percent for the production of chemicals and materials. Natural regeneration of fossil resources through the carbon cycle is significantly slower than their current rate of exploitation. A small number of countries possess the major reserves of fossil fuels, which additionally increases unsustainability of their production. Furthermore, increased greenhouse gas emission arises from fossil fuel combustion and land-use change as a result of human activities, and consequently results in an acceleration of the global warming crisis. In most developed countries, governments stimulate the use of renewable energies and resources with following major goals: (i) to secure access to energy, (ii) to mitigate climate changes, (iii) to develop/maintain agricultural activities and (iv) to ensure food safety. Affordable energy, climate change and social stability, as the three pillars of sustainability, are directly related to the above mentioned major goals. Current situation of global warming and all fossil-based problems could be successfully altered by replacing fossil with renewable resources, which are more uniformly distributed and cause fewer environmental and social concerns.

During the last decades of the 20th century, there was an enormous interest in the production and usage of liquid biofuels (biodiesel or bioethanol) as promising substitutes for fossil fuels. Biofuels manufactured from plant-based biomass represent renewable energy resources. The use of this feedstock would reduce fossil fuel consumption and consequently the negative impact on the environment. Development of biorefinery aims to fulfil the sustainability criteria for biofuel production. Biorefinery is an integrative and multifunctional concept that uses biomass for the sustainable production of different intermediates and products as well as the complete possible use of all feedstock components. The concept includes selective transformation of the different molecules available in the biomass into biofuels, but also into pharmaceuticals, pulp, paper, polymers and other chemicals, as well as food or cattle feed. A wide range of technologies are able to separate biomass resources into their building blocks, like carbohydrates, proteins, fats,??etc.. The plant that produces lignocellulose-containing raw materials could be a good example of biorefinery concept where cellulose and hemicellulose produce simple (fermentable) sugars and lignin produces target compounds (e.g. polymers, resins, pesticides, levulinic acid and other materials). Recently, there have been considerable efforts to improve selectivity and efficiency of lignin depolymerization and upgrading processes for the target compound production. The catalytic hydrodeoxygenation process is the most promising way for target compound production from lignin.

In general, the biorefinery process usually comprises the following stages: pretreatment and preparation of biomass, separation of biomass components and subsequent conversion and product purification steps. There are two basic approaches for biorefinery concept implementation: bottom-up and top-down. Bottom-up biorefinery approach is characterized by the spreading of current biomass processing facilities (the production of only one or a few products) into a biorefinery with the aim to obtain an enlarged range of products and/or an increase of usable biomass fractions through the connection to additional technologies. An example of bottom-up biorefinery is the wheat and corn starch biorefinery (Lestrem, France) that starts as a simple starch factory. It gradually expanded the number of products, like starch derivatives and starch modifications, chemicals and fermentation products. A corn starch biorefinery in the USA (Decatur, Illinois) and wood lignocellulosic biorefineries in Austria (Lenzing) and Norway (Sarpsborg) also use bottom-up approach.

The new top-down approach is a highly integrated system established for the use of various biomass fractions and generation of different products for the market (zero-waste generation). The objective is to obtain the complete use of biomass (e.g.??wood lignocellulose, grain and straw from cereals or green grasses). An example of top-down approach is Austrian Green Biorefinery. It uses green grass silage as feedstock for the production of biobased products like proteins, lactic acid, fibres and biogas from the remaining biomass. Furthermore, green grass juice and silage juice (complex nitrogen and phosphate sources) served as cultivation medium constituents for growth and polyhydroxyalkanoate production by??Wautersia eutropha. Top-down biorefineries are still at the research and development stages and their demonstration plants are mainly based in the USA, Europe and some other industrialized countries.

However, both biorefinery concepts still need a lot of engagement to fulfil all requirements for production of high- -quality biofuels, value-added chemicals or other products, mainly in terms of the optimisation and upgrading of existing conversion processes, development of new processes and products with justified costs, and the industrial scale-up of existing ideas.

Bioethanol, as an alternative to the fossil fuels, is mainly produced by yeast fermentation from different feedstocks. It is a high octane number fuel and its physicochemical features are considerably different compared to the gasoline.

Bioethanol serves mostly in the transport sector as a constituent of mixture with gasoline or as octane increaser (ethyl tertiary butyl ether (ETBE), consisting of 45% per volume bioethanol and 55% per volume of isobutylene). Many countries use ETBE instead of methyl tertiary butyl ether (MTBE), which serves for octane number increase, but it is prohibited in the USA and Canada due to cancerous emissions. Bioethanol is mixed with gasoline at the volume fractions of 5, 10 and 85% (fuel names E5-E85). A total of 85% bioethanol by volume can only be used in flexible fuel vehicles (FFV), while mixtures of 5 and 10% by volume can be used without any engine modifications. However, problems related to the use of bioethanol are: corrosive effect on fuel injector and electric fuel pump (bioethanol is hygroscopic in nature), engine startup problem in cold weather conditions (pure ethanol is hard to vaporize) and the tribological effect on lubricant properties and engine performance. Bioethanol inside lubricant significantly reduces the properties and performance of engine oil. It is miscible with water, but immiscible with oil. Therefore, bioethanol has high potential for emulsion formation (bioethanol-water-oil mixture), which causes serious engine failures. There are different methods to improve the performance of engines (e.g. laser texturing, coatings, mass reduction of engine parts and lubricant composition) and extend their lifetime through the friction and wear reduction. The use of synthetic oil is one possibility to solve the above-mentioned issues.

Data for 2016 show that the global bioethanol production was 100.2 billion litres. Annual bioethanol production is constantly increasing, and the prediction of worldwide bioethanol production and its consumption is an increase to nearly 134.5 billion litres by 2024

Raw Materials and Their Pretreatment for Bioethanol Production

Different types of biomass have a potential as raw materials for bioethanol production. Because of their chemical composition,??i.e.??carbohydrate sources, they mostly form three groups: (i) sugar-containing raw materials: sugar beet, sugarcane, molasses, whey, sweet sorghum, (ii) starch-containing feedstocks: grains such as corn, wheat, root crops such as cassava, and (iii) lignocellulosic biomass: straw, agricultural waste, crop and wood residues. However, these sugar- and starch-containing feedstocks (first generation) compete with their use as food or feed, thus influencing their supply. Therefore, lignocellulosic biomass (second generation) represents an alternative feedstock for bioethanol production due to its low cost, availability, wide distribution and it is not competitive with food and feed crops.

Raw materials that contain sugar

Sugar cane and beet are the most important sugar-producing plants in the world. Two-thirds of the world sugar production are from sugar cane and one-third is from sugar beet. They can be easily hydrolysed by the enzyme invertase, which is synthesed by most??Saccharomyces species. Therefore, the pretreatment is not required for bioethanol production from the feedstocks containing sugar (sucrose), which makes this bioprocess more feasible than from feedstocks containing starch. Sugar crops need only a milling process for the extraction of sugars to fermentation medium, and here ethanol can be produced directly from juice or molasses.

Sugar cane as a raw material for bioethanol production provides certain advantages, since it is a semi-perennial crop that does not require many agricultural operations that are usually needed for raw crop processing, and its biomass is used for heat and electricity. Sugar cane is less expensive than other raw materials used for bioethanol production??due to easier processing and higher productivity. However, many efforts still aim at the improvement of bioethanol production from sugarcane. This includes development of new sugar cane varieties with higher sugar contents and resistance to diseases, larger yield per hectare and greater longevity.

In Europe, sugar production is mainly based on the use of sugar beet as raw material. Raw, thin and thick juice, as intermediate formed during sugar beet processing, as well as high purity crystal sugar, could be converted into bioethanol and/or bio-based products. Raw sugar beet cossettes are also suitable substrates for bioethanol production. The use of sugar processing intermediates determines bioprocess configuration, their microbiological stability and transport properties. Sugar syrup and granulated sugar can serve as substrates for bioethanol production during the whole year. Futhermore, they can also serve as precursors for different chemical intermediates or final products (e.g.??surfactants;??8).

Molasses, a main byproduct of the sugar industry, serves mostly as a substrate for yeast, bioethanol and biochemical production, but it can also be suitable for feedstuff production. Total residual sugars in molasses can amount to 50???60% (m/V), of which about 60% is sucrose, which makes this substrate suitable for large-scale bioethanol production. Sugar cane and beet molasses are byproducts of the manufacture or refining of sucrose from sugar cane and beet. Cane molasses contains not less than 46% of total sugars and sugar beet molasses not less than 48% (m/V). Molasses is also a byproduct in the production of dried citrus pulp, with not less than 45% (m/V) total sugars. Glucose manufacture from starch (corn or grain sorghum; enzymes or acids are used for starch hydrolysis) also yields molasses. Starch molasses contains about 43% (m/V) reducing sugars and 73% (m/V) total solids.

Another sugar-containing material that can be used for bioethanol production is whey, a byproduct of cheese manufacture, containing around 4.9% (m/V) lactose. Due to the relatively low sugar content, a bioethanol plant of modest size requires a sizeable whey volume. The feasibility of a new bioethanol plant depends on the cost of whey permeate as feedstock as well as the final bioethanol price that is closely related to the production technology and bioprocess performance.

Raw materials that contain starch

Grain crops (e.g.??corn, barley, wheat or grain sorghum) and root/tubular crops (e.g. cassava, potato, sweet potato, Jerusalem artichoke, cactus or arrowroot) contain large quantities of starch. Isolated native starch from different sources can be used for further conversion into bio-based products and/or the bioethanol production. The residue from starch isolation contains proteins and fibre, which has a great potential for application in food and feed production. The biggest corn starch production is in the USA and it represents more than 80% of the worldwide market. In the USA, corn is a source of over 95% of bioethanol production and the rest is produced from barley, wheat, whey and beverage residues. The grain sorghum cultivating regions in the USA show an increasing interest in bioethanol production from this crop. Furthermore, the economic viability of bioethanol production from cassava in Thailand was also under investigation. Cassava tubers contain nearly 80% by mass starch and below 1.5% by mass proteins. Pretreatment of cassava tubers for bioethanol production includes following operations: cleaning, peeling, chipping and drying. After that, the dried cassava chips are used for bioethanol production.

Starch is a mixture of linear (amylose) and branched (amylopectin) polyglucans. The crucial enzyme for starch hydrolysis is ??-amylase, active on ??-1,4, but not on ??-1,6 linkages in amylopectin. For bioethanol production from starch-containing feedstocks, it is necessary to perform the starch hydrolysis (mostly by ??-amylase and glucoamylase) into glucose syrup, which can be converted into ethanol by yeast??Saccharomyces cerevisiae. This step is an additional cost compared to the bioethanol production from sugar-containing feedstocks. Bacterium??Bacillus licheniformis??and genetically modified strains of bacterium??Escherichia coli??and??Bacillus subtilis??produce ??-amylase, while moulds??Aspergillus niger??and??Rhizopus sp. produce glucoamylases.

Under anaerobic conditions, yeast??S. cerevisiae metabolizes glucose into ethanol. The maximum conversion efficiency of glucose into ethanol is 51% by mass. However, the yeast also uses glucose for cell growth and synthesis of other metabolic products, thus reducing the maximum conversion efficiency. In practice, 40 to 48% by mass of glucose is actually converted into ethanol.

In comparison to ethanol production from sugar-containing raw materials, ethanol obtained from starch improves enzyme application and yeast strains with high ethanol tolerance.

Microalgae are a potential renewable source of biomass for biofuel production because they are capable of converting CO2??into lipids and polysaccharides. Therefore, industrial CO2??could be collected and used for cultivation of microalgae as part of strategy for reduction of CO2 emission in atmosphere. Microalgae can accumulate starch as a reserve polysaccharide, which can be used for bioethanol production (third generation) after pretreatment process. Furthermore, residual biomass (containing organic matter and minerals) after bioethanol production can serve as biofertilizer. Thus, it is obvious that the use of biorefinery concept can considerably improve bioethanol production from microalgae.

Raw materials that contain lignocellulose

Production of bioethanol from the raw materials that contain lignocellulose is attractive and sustainable because lignocellulosic biomass is renewable and non-competitive with food crops. Furthermore, the use of bioethanol obtained from lignocellulosic biomass is related to the considerable reduction of greenhouse gas emission. Lignocellulosic biomass is almost equally distributed on the Earth, compared to the fossil resources, which provides security of supply by using domestic energy sources. It can be obtained from different residues or directly harvested from forest and its price is usually lower than of sugar- or starch-containing feedstocks, which require full agricultural breeding approach. Raw materials that contain lignocellulose for bioethanol production form six main groups: crop residues (cane and sweet sorghum bagasse, corn stover, different straw types, rice hulls, olive stones and pulp), hardwood (aspen, poplar), softwood (pine, spruce), cellulose wastes (e.g. waste paper and recycled paper sludge), herbaceous biomass (alfalfa hay, switchgrass and other types of grasses) and municipal solid wastes.

The average lignocellulosic biomass contains 43% cellulose, 27% lignin, 20% hemicellulose and 10% other components. Compositional variety of lignocellulosic biomass could be an advantage (availability of more products than obtained in petroleum refineries, and a broader range of feedstocks), but also a disadvantage (need for a large range of technologies). Such heterogeneous structure of lignocellulosic biomass requires more complex chemical processes than uniform and consistent raw materials needed in chemical industry. Furthermore, harvesting of lignocellulosic crops is usually not possible throughout the whole year, which makes it more difficult for biomass suppliers. Therefore, this problem has to be solved by biomass stabilization in order to be available for long-term storage, and to ensure continuous work of biorefinery throughout the year.

The hydrolysis of lignocellulosic biomass to monomeric sugars is necessary before microorganisms can metabolize them. Acids, alkalines or enzymes usually perform this process. Physicochemical, structural and compositional factors can considerably slow down this process. Therefore, alkaline pretreatment step is usually necessary to obtain conditions for an efficient enzymatic hydrolysis. In the pretreatment, reduction of polymerization degree and crystallinity index, disruption of the lignin-carbohydrate linkages, removal of lignin and hemicelluloses and increase of material porosity have to occur in order to insure the efficient enzymatic hydrolysis of lignocellu

Second Generation Bioethanol Process Technology

 Overview: Second Generation Bioethanol Process Technology

- Atul Choudhari.

Biofuels provide an attractive and sustainable energy option as they are considered to be clean fuels

having ‘very low to no sulphur’ content. Biofuels therefore help in creating a positive environmental impact.

Bioethanol is one such fuel that can be blended with gasoline. Typically and conventionally, bioethanol is

extracted from sugars. Bioethanol can be produced at industrial scale through the sugar fermentation route.

The bioethanol technology is termed as either first generation (1G) or second generation (2G) depending

upon the origin of such sugars. While the 1G bioethanol technology uses starch as a source of sugar, the

2G bioethanol technology uses cellulose and hemicelluloses as a source of sugar. Starch required in 1G

technology can be found in various feed stocks such as cereals (wheat, corn, sorghum barley, etc) and

sugarcane. Feedstock such as wheat straw, corn, wood, agricultural residues or municipal solid waste are

typically lingo-cellulosic materials and are used as a source of bioethanol in 2G technology. As compared

to 1G technology, which use grain as feedstock, the 2G technologies use crop residues, a waste that

otherwise would be of no value. This article provides an overview of the 2G bioethanol technology.

Advantages of Bioethanol:

There are number of advantages of using bioethanol as fuel. Some of the benefits are as below.

 Reduced dependency on crude oil imports: For oil importing countries like India, The major driving

force is to reduce their dependency on fossil fuels. It benefits energy security as it can reduce

crude oil by using domestically produced energy sources. Countries like India, having a limited

access to crude oil resources, can grow crops for energy use and gain some economic freedom.

 Cleaner environment: Due to the fact that the exhausts from the automobile engines using

bioethanol blended gasoline is more cleaner in nature, the second major benefit of using

bioethanol is its ability to reduce the overall carbon footprint and their use help in reduction of

greenhouse gas (GHG) emissions. It will also reduce the GHG emissions by reducing the of

agriculture residues burning.

 Renewable energy source: Bioethanol is produced using plant materials such as corn, sugarcane,

crop residues, etc. Since, all these are crops can be grown; bioethanol fuel is a renewable energy

source.

 Financial benefit for farmers: Agricultural residues and wastes which otherwise are burnt by

farmers can be utilized for producing bioethanol.

Raw material components:

As stated earlier, the 2G bioethanol technology uses ligno-cellulosic biomass as a feedstock.

Lignocellulosic biomass is mainly composed of plant cell walls. It essentially contains three major

components viz. Lignin, Cellulose, and Hemicelluloses. Cellulose and Hemicelluloses are the structural

carbohydrates while lignin is heterogeneous phenolic polymer.

Cellulose is a polysaccharide made up of linear glucan chains held together by intra molecular hydrogen

bonds and by intermolecular Van-der Waals forces. In order to obtain glucose, the crystalline cellulose

must be subjected to some preliminary chemical or mechanical degradation.

Hemicellulose consists of short, highly branched chains of sugars. Hemicelluloses are highly amorphous

and branched structures. It contains pentoses, hemicelluloses chains. Compared to cellulose, the

hemicelluloses can easily be broken down to form their simple monomeric sugars. The exact sugar

composition of hemicelluloses can vary depending on the type of plant.

Lignin is a non-sugar-based polymer. Lignin is not a suitable component for microbial fermentation process.

It inhibits microbial growth and fermentation. However, lignin can be used as energy source as it yields.

more energy when burned, and thus can be utilized for combined heat and power production in the

bioethanol process.

Process Description:

The bioethanol process is carried out in following four major steps.

1. Pre treatment: Physical or chemical pre-treatment of the fibers to expose the cellulose so as to

reduce its crystallinity.

2. Hydrolysis : Cellulose polymer is hydrolysed with enzymes or acids, to convert it into simple

(glucose) sugars

3. Fermentation: Microbial fermentation of simple sugars to form ethanol.

4. Distillation and dehydration to produce 99.5% vol. fuel grade ethanol.

Pretreatment:

Due to the presence of lignin in ‘Lignocellulosic “materials, and compared to the accessibility of sucrose in

sugar cane and starch in grains, cellulose and hemicelluloses are not easily and readily available for

saccharification and fermentation. A “pre-treatment” step is hence required to facilitate conversion of

cellulose and hemicelluloses to fermentable sugars.

The pre-treatment process converts hemicellulose carbohydrates into soluble sugars (like glucose, xylose,

etc.) by hydrolysis reactions in which acetyl groups in the hemicellulose are liberated in the form of acetic

acid. Biomass feedstock is chemically treated by disrupting cell wall structures in the pre-treatment step

which facilitates downstream enzymatic hydrolysis. This section is also termed as ‘Delignification’ section

as the pre-treatment drives some lignin into solution. This step reduces cellulose crystallinity and chain

length. Process parameters such as residence time, temperature, and catalyst loading affects the pre

treatment process. The pre treated biomass is sent to the hydrolysis reactor.

Hydrolysis:

Hydrolysis process is used to convert hemicellulose and cellulose content of lignocellulosic biomass into

fermentable monomeric sugars. This process can be carried out by two different routes. These routes are

Acid hydrolysis and Enzymatic hydrolysis.

In acid hydrolysis process, mineral acids such as HCl, H2SO4, HNO3, or HF are widely used for hydrolysing

lignocellulosic biomass. In enzymatic hydrolysis, Cellulose is converted to glucose using cellulase

enzymes. Enzymatic hydrolysis process is also termed as ‘Enzymatic Saccharification’ process. A

cellulase enzyme is prepared from mixture of enzymes (catalytic proteins) which work together to break

down cellulose fibers into glucose monomers.

For higher conversion and it’s suitability to the lower grade of metallurgy, enzymatic hydrolysis route is

preferred over the acid hydrolysis route.

The glucose and other sugars obtained from hydrolysis of hemicelluloses are co-fermented to form ethanol

in the next step.

Fermentation:

Fermentation process step is similar to the 1G ethanol technology. In this step, the hexoses and pentoses

are converted into ethanol by employing variety of micro organisms, such as yeast, bacteria, fungi, etc.

Depending on how the enzymatic hydrolysis and fermentation steps are integrated, the technology can

follow either of following route.

 Separate Hydrolysis and Fermentation

 Separate Hydrolysis and Co-fermentation

 Simultaneous Saccharification and Co-fermentation

Indian Scenario:

The practice of blending ethanol in gasoline was started in India in 2001. Government of India, in 2003,

mandated blending of 5% ethanol with gasoline in 9 States and 4 Union Territories. This was subsequently

continued on an all-India basis in November 2006 (in 20 States and 8 Union Territories except a few North

East states and Jammu & Kashmir). Indian Oil companies were asked to increase the ethanol blending

target to 15% by Ministry of Petroleum and Natural Gas, on 1 September, 2015 and achieve this blend in

as many states as possible.

At 10% blending, the projected ethanol demand is ~5500 million liters per anum by year 2021-2022. It

would certainly require significant investments in near future. Presently, First few plants to produce

bioethanol using 2G technologies are under consideration and are at various stages of planning and

design.

Future Technology:

Third generation (3G) bioethanol technology is based on ethanol production from Microalgae. Currently,

Microalgae is gaining increased attention as it is an alternative renewable source of biomass which can be

used for 3G bioethanol production. The increased interest to use microalgae is also attributed to the fact

that it can be produced all year along and does not require any pesticides or herbicides. It can be produced

in sea water or brackish water and thus do not compete with agricultural land. Comparatively, microalgae

have potential to reduce freshwater consumption as it requires less water than terrestrial crops.

Another technology to produce bioethanol from the CO2 emission sources (Iron and steel producers) is also

recently commercialized.

Concluding Remarks:

Bio-ethanol is considered as an important renewable fuel. The Indian economy is growing at a rate of

approximately 7% to 7.5% resulting in the increased demand for energy. Bioethanol presents a sustainable

source of energy. 2G Bioethanol technologies are being implemented in India.

TCE is associated with one of the first 2G bioethanol plants being installed in India and have first hand

experience of commercializing such technology.
