1 What is bioethanol and what is it used for?
Bioethanol
is ethanol that has been manufactured from an organic feedstock
(biomass). The bioethanol will mostly be blended into gasoline as a
renewable transport fuel component. Bioethanol for fuel is available in
blends such as E5, E10, and E85. The E stands for Ethanol and the number
is the percentage of bioethanol in the blend. Hence, E85 is composed of
85% bioethanol and 15% gasoline (petrol). The market for biofuels, such
as bioethanol, is growing rapidly around the World, driven by
legislation, as Nations seek to combat climate change, reduce their
dependency on fossil fuels for road transport and create increased
security of energy supply. Bioethanol can also be used as a renewable
chemical intermediate, for example, for the manufacture of renewable
ethylene and hence bio-polyethylene.
2 How does bioethanol reduce CO2 emissions?
Plants
grow through a process called photosynthesis. They harness energy from
the sun to extract CO2 from the atmosphere and water from the soil to
lay down biomass. When the biomass is used to make bioethanol and the
bioethanol is burned as a fuel, the CO2 is simply returned to the
atmosphere. However, if fossil fuels are used in the production and
transport of the crops and in the production of the bioethanol, then the
Greenhouse gas savings over the life cycle of the biofuel will be
reduced.
3 What Greenhouse gas savings are typically delivered from bioethanol today?
The
recently published Gallagher review shows that bioethanol produced
today delivers savings of up to 70% compared to gasoline. The best
performing bioethanol is sugar cane ethanol from Brazil. However, the
review also shows that some bioethanol production does not deliver any
savings compared to gasoline (petrol).
4 What Greenhouse gas savings are expected from the INEOS Bio Ethanol?
The
bioethanol produced from the INEOS Bio process using waste biomass feed
materials is expected to deliver at least 90% lower net emissions of
CO2 than burning petrol gasoline (petrol). Hence, using the clean,
renewable INEOS Bio Ethanol will emit 90% lower Greenhouse gases than
burning gasoline (petrol) in your car.
5 Where is most bioethanol produced today and how is it made?
Bioethanol
is manufactured all around the World from sugar and starch crops using
long-established technologies. Brazil and North America are the World’s
largest producers of bioethanol today. Brazil manufactures bioethanol
predominately from sugar cane and North America manufactures bioethanol
predominately from corn, a starch crop. Other crops can also be used
such as wheat and sugar beet. In the case of corn, the starch is first
extracted from the crop and then converted to sugars. The sugars are
then fermented to an ethanol solution by enzymes. The solution is
finally concentrated to hydrous ethanol (96% purity) or anhydrous
ethanol (99.7% purity).
6 What impact will the INEOS Bio process have on recycling?
The
INEOS Bio process is fully compatible with high recycling rates. We
fully support the recycling agenda. Recyclable materials will be
extracted from the waste streams in the most appropriate way. Organic
wastes will also be extracted and treated in the most appropriate way.
7 How big is the global bioethanol market potential?
Very
large. FlexFuel vehicles have been designed to run on either petrol
gasoline (petrol) or ethanol (up to 100% concentration). The majority of
new vehicles bought in Brazil are FlexFuel vehicles because ethanol
made from sugar cane in Brazil is cost-competitive with gasoline
(petrol). The bottleneck for bioethanol growth outside of Brazil is not
the lack of a market demand but the lack of supply of sustainable,
cost-competitive bioethanol. In order to stimulate growth in the
biofuels markets, the USA and Europe have introduced biofuel usage
targets going forwards.
8 What are the biofuel targets in Europe and the USA?
The
targets are: 5% biofuel use by 2010 and 10% by 2020 in Europe, and 36
billion gallons of biofuel use annually by 2022 in the USA, of which 21
billion gallons must be from second generation technologies. However,
these targets are subject to revision, and the Gallagher review, for
example, recommends a slower increase in biofuel targets in Europe than
is currently planned.
9 What is the Gallagher Review and what does it say?
Biofuels
have been proposed as a solution to several pressing global concerns:
energy security, climate change and rural development. This led to the
European Union agreeing the Biofuels Directive and the setting of
targets for biofuels use going forwards. Five years later, there is
growing concern about the role of biofuels in rising food prices,
negative effects from changing land use, and doubts about the climate
benefits. This has led to serious questions about their sustainability
and extensive campaigns against higher targets. The Gallagher review was
commissioned by the independent UK Renewable Fuels Agency (RFA) for the
UK Government in response to these concerns. The RFA proposes that the
current RTFO target for 2008/09 (2.5% by volume) should be retained, but
the proposed rate of increase in biofuels be reduced to 0.5% (by
volume) per annum rising to a maximum of 5% by volume by 2013/14. This
compares with the RTFO's current target trajectory of 5% by 2010. It
recommends that targets higher than 5% by volume (4% by energy) should
only be implemented beyond 2013/14 if biofuels are shown to be
demonstrably sustainable (including avoiding indirect land-use change).
Based on current judgment, it proposes targets for renewable transport
fuels of between 5% and 8% (by energy) for the EU for 2020 (including
1-2% from advanced technologies).
10 What is the INEOS Bio response to the Gallagher review?The
INEOS Bio process fully addresses all the concerns raised in the
Gallagher review. The bioethanol produced from the INEOS Bio process
will deliver 90% Greenhouse gas savings compared to burning gasoline
(petrol). This is better than any other bioethanol production today. The
INEOS Bio Ethanol also does not require food crops and so the
production of clean, renewable fuel can be separated from food
production and prices. In addition, the INEOS Bio Ethanol does not
compete for agriculture land use.
11 How much bioethanol is used today in the USA and in Europe?
The
fuel (petrol) market in Europe is currently just over 100million tonnes
and bioethanol usage is around 2.8 million tonnes (approaching 3%). In
the USA the gasoline market is around 140 billion gallons and bioethanol
usage is around 9 billion gallons in 2008 (around 6.5%). The vast
majority of this bioethanol is sold in blends of up to 10% ethanol in
gasoline (petrol) (E10), which can be used on unmodified vehicles. The
number of service stations in Europe and the USA which sell E85 fuel
(85% ethanol in gasoline (petrol)) is still very small (around 1% of
service stations in the USA and less in Europe). Around 150million
gallons of E85 was sold in the USA in 2007. The INEOS Bio process has
the potential to produce cost-effective bioethanol, which does not use
food crops, and does not use agricultural land.
12 What biomass feedstocks will the INEOS Bio process be using?
The
attraction of the INEOS Bio process is that it can take wastes that
people do not want and convert them into clean, liquid transport fuels
that everyone wants. The INEOS Bio process is ‘feed flexible’ and we
will be targeting a mixture of household wastes, commercial and
industrial wastes, agricultural wastes and forestry wastes.
13 How much bioethanol does the INEOS Bio process produce from a tonne of waste?
The
INEOS Bio process converts one metric tonne of dry, ash free biomass
into about 400 litres (315kg) of bioethanol in a commercial process.
14 Most biomass is not dry. Can the INEOS Bio process use wet feeds?
The
INEOS Bio process can efficiently dry biomass feeds to the desired
water content using low-grade waste heat from the process. Very wet
biomass such as animal slurries and some food waste may be best treated
in an anaerobic digestion plant.
15 Will you be using waste plastics to make ethanol?
Our
intention is to commercialise the INEOS Bio technology using a variety
of biomass feeds to manufacture clean, renewable bioethanol fuel for the
road transport sector. Our view is that plastics should be
recycled wherever and whenever possible in the most sustainable way.
However, waste biomass from households may contain a small amount of
residual, contaminated plastic films and containers, which may not be
economic to recycle. As our process can process plastics as well as
biomass, it is most probably the best practical environmental option to
leave this small amount of residual waste plastics in the biomass waste
rather than use valuable energy and resources unnecessarily to remove
them.
