Hierarchy of Controls: The Foundation of Effective Risk Management
This visual reinforces a critical safety principle: not all controls are equally effective. The Hierarchy of Controls guides us to manage workplace hazards in the right order—starting with solutions that remove risk at the source and ending with those that rely most on individual behavior.
From Elimination and Substitution, through Engineering and Administrative Controls, to PPE, the message is clear:
the higher we control the hazard, the safer and more reliable the outcome.
PPE is essential—but it should be the last line of defense, not the first choice.
Strong safety performance is built by designing out risk, not managing it after exposure

ARLIAMENT QUESTION: CIRCULAR ECONOMY OF BATTERIES
ReplyDeletePosted On: 18 DEC 2025 2:45PM by PIB Delhi
Ministry of Environment, Forest and Climate Change (MoEF&CC), Government of India has published the Battery Waste Management Rules, 2022 on 24th August, 2022 for environmentally sound management of waste batteries. These rules cover all types of batteries viz. Electric Vehicle batteries, portable batteries, automotive batteries and industrial batteries. The rules are based on the concept of Extended Producer Responsibility (EPR) where the producers, including importers, of batteries have been given annual targets for collection and recycling or refurbishment of waste batteries against the batteries placed in the market. The rules mandate producers to use minimum percentage of domestically recycled materials in manufacturing of new batteries from FY 2027-28 onwards.
Centralized online EPR portal has been developed for registration of producers and recyclers/ refurbishers, exchange of EPR certificates between producers and recyclers/ refurbishers and filing returns by producers and recyclers/ refurbishers. So far, 4022 producers and 487 recyclers have been registered under these rules on the EPR portal. After the notification of these rules, around 58.26 lakh tonnes of battery waste has been recycled. EPR mechanism under Battery Waste Management Rules, 2022 recognise only EPR certificates generated by registered recyclers. The EPR mechanism encourages formalisation of informal sector to generate revenues from exchange of EPR certificates with producers, in addition to the revenue generated from sale of recycled materials.
To upgrade informal sector into formal value chain, a project on ‘Informal Sector Capacity Building Upgradation with formation of recycling clusters under the Scheme ‘Micro & Small Enterprises Cluster Development (MSE-CDP) of MSME’ has been initiated by MeitY. MeitY has transferred the cost-effective Li-ion battery recycling technology indigenously developed by Centre for Material for Electronics Technology (C-MET) to several recycling industries and start-ups as part of Mission LiFE under ‘Promote circularity campaign’.
The Government has approved the PLI-ACC scheme ‘National Programme on Advanced Chemistry Cell (ACC) Battery Storage’ in May 2021, with an outlay of Rs. 18,100 Crore for 50 GWh ACC capacity. This initiative has acted as a catalyst for Indian cell manufacturers to setup a cell manufacturing unit. Apart from the PLI beneficiaries, more than 10 companies have announced setting up cell manufacturing unit for more than 100 GWh additional capacity. Ministry of Mines has launched the scheme ‘Critical Mineral Recycling Incentive Scheme’ aimed at developing the recycling capacity in the country for extraction of critical minerals from secondary sources such as E-waste, spent Lithium-ion Batteries (LiBs), and other scrap.
Further, MoEF&CC facilitated the signing of Memorandum of Understanding between CSIR laboratories, like National Metallurgical Laboratory (NML), Advanced Materials and Processes Research Institute (AMPRI) and Central Electrochemical Research Institute (CECRI), and recycler organisations, to facilitate technology transfer and technical support to establish state-of-the-art recycling infrastructure, support domestic waste recycling, and secure critical mineral supplies through advanced recycling processes.

SOP for PV Module Cleaning

Cleaning of Solar PV Modules is a very important O&M practice to keep the module efficiency up and ensure high output from the plant, here is the SOP for PV Module cleaning:
Safety Precautions: Before starting any cleaning activity, ensure to take necessary safety precautions to avoid any hazards. Wear protective equipment, such as gloves and safety glasses.
Identify the cleaning schedule: The cleaning schedule can vary based on the site location, weather conditions, and the level of soiling. Develop a cleaning schedule based on the site-specific needs and environmental factors.
Water quality: The quality of water is crucial when cleaning solar modules. High mineral content water may cause mineral deposits on the glass surface, reducing the module's performance. Water must be free from grit and physical contaminants that could damage the panel surface. Use deionized, or reverse osmosis and natural pH water to prevent mineral deposits. If RO is not available, rainwater or tap water with low mineral content and a total hardness that is less than 75mg/L may be used. As per various research the TDS should not be greater than 30mg/L.
Cleaning solution/agents: Dilute a non-abrasive cleaning solution in water according to the manufacturer's instructions. The cleaning solution should be specifically designed for solar modules and should not contain any harsh chemicals.
Equipment Preparation: Before cleaning the modules, ensure that all the cleaning equipment, including brushes, sponges, and squeegees, are clean and free of dirt, debris, and other contaminants. Don't use metal objects or harsh abrasive products for removing caked on materials – scratching the glass on a solar panel can affect its performance as scratches will cast shadows.
Cleaning Time: The recommended time for cleaning modules is during low light conditions when generation is lowest. However, when sun shines during the day, the temperature of the PV panel rises and cleaning solar panels with cold water in evening may result in thermal shock/crack for panel which can permanently damage them. Hence, the best time to clean Solar Panels is early morning, when the plant is not in operation, risk of electrical shock hazard is minimum and also temperature of solar panels is not high. i.e. the temperature difference of cleaning water and the panel is less.
Water Pressure: Water pressure should not exceed 35 bar at the nozzle. Use of high pressure hoses for cleaning may exert excess pressure and damage the modules.
Module Cleaning: Start cleaning from the top row and work downwards. Use a soft-bristled brush or sponge to remove loose dirt, debris, or bird droppings. Wet the surface of the modules with water and then apply the cleaning solution using a soft-bristled brush or sponge. Allow the solution to soak for a few minutes, then scrub the surface lightly. Finally, rinse the modules with water.
Drying the modules: After rinsing the modules, use a squeegee or a lint-free cloth to remove excess water from the surface. Let the modules air dry completely before reconnecting them.
Inspection: Once the modules are dry, visually inspect them for any damages, cracks, or scratches. Repair or replace any damaged modules as needed.
Documentation: Maintain a record of the cleaning schedule, the cleaning solution used, and any damages observed during the cleaning process.
Greenko Group has signed a MoU with Bihar State Power Generation Company Limited (BSPGCL) for the development of a 1200 MW Pumped Storage Power Project in Nawada district, Bihar.
ReplyDeleteThe MoU was executed in the presence of Hon’ble Chief Minister - Shri Nitish Kumar ji, Hon’ble Deputy Chief Minister - Shri Samrat Choudhary ji, Hon’ble Energy Minister - Shri Bijendra Prasad Yadav ji, Hon’ble Water Resources Minister - Shri Vijay Kumar Choudhary ji, along with senior officials of the Government of Bihar, and was signed on behalf of Greenko Group by Mr. Anil Chalamalasetty, CEO & MD, and Mr. Krishna Tungaturthi, Executive Vice President, PSP.
The proposed pumped storage project is envisioned to provide grid-scale energy storage, support peak demand management and enhance overall grid stability thereby strengthening the State’s power infrastructure.
Greenko remains committed to working closely with State Governments to develop storage-led clean energy infrastructure, contributing to a resilient, sustainable, and future-ready power system.
