Green Chemistry for sustainability
We are aligning our businesses along the core principles of Green Chemistry to drive sustainability and organisational resilience
At Tata Chemicals, we are committed to align our business model and growth along the sustainability dimensions of climate change, circular economy and biodiversity.
Green Chemistry
We are investing in Green Chemistry as part of the sustainability commitment to ensure circularity of feedstock, low energy intensity and zero effluents. Our indigenously developed Fermentation Platform for synthesis of chemicals – a technology to produce Fructo-Oligosaccharides from sugar – is one such example.
Climate change
With climate change becoming intense and a major global challenge, we have undertaken an approach to balance the growth strategies and business expansion with the impact on planet and society. We have committed to reduce our carbon footprint as per the Science Based Target initiatives (SBTi) guidelines by 30 per cent by 2030.
Key levers have been identified to reduce, reuse and recycle key natural resources and waste. We are also continuously seeking ways to reduce our operational footprint and emissions, improve energy efficiency, use more renewable energy and reduce carbon intensity.
Energy conservation
In our India operations, the Mithapur unit started using biomass as feedstock which will help reduce conventional energy consumption. The Innovation Centre successfully commissioned a 100 kW Rooftop Solar Project which will reduce the electricity from grid by 25 per cent.
Emission management
We commissioned UK’s first at scale Carbon Capture and Utilisation facility (CCU) that not only reduces carbon intensity but provides a sustainable inhouse source of critical input. Successfully operationalised in FY22, the CCU facility captures food and pharmaceutical grade CO2 for consumption in the Sodium Bicarbonate plant.
The Indian operations installed a quadruple effect evaporator at the Mithapur plant, resulting in 150 equivalent kilo tonnes of carbon savings.
The US operations commissioned the Dry Sorbent Injection (DSI) system, resulting in SO2 emissions being below the new Wyoming State requirements. Owing to operational difficulties in the system, a new DSI mill has been installed for the anticipated change in coal mix from Kemmerer in December 2022.
Waste management
We ensured responsible waste management practices involving 100 per cent recycling of plastic waste, fly ash and safe disposal of waste across locations.
Water conservation/management
All our plants across all global locations continue to adopt measures to reduce fresh water consumption. The Indian operations has an installed water harvesting capacity of 441 Million Cubic Feet (MCFT) which ensures lower fresh water withdrawal. The US operations installed flow meters to better track water consumption measures and take appropriate actions. The UK operations also has installed water harvesting system as well as large state-of-the-art recycle and reuse system.
