Effective waste management is a priority for Nagpur's solvent extraction plants. In Plant E, they have implemented a zero - waste policy. They have developed a comprehensive waste treatment system that aims to recycle or reuse as much of the waste generated during the extraction process as possible.

The solid waste, such as the spent raw materials, is sent for further processing to extract any remaining valuable components. The liquid waste, which contains solvents and other substances, is treated through a series of purification processes. The purified solvents can be reused in the extraction process, while the other treated substances are disposed of in an environmentally friendly manner.

4.2. Emission Control

Emission control is also a significant part of environmental sustainability. Plants in Nagpur have installed advanced air pollution control devices. For example, Plant F has installed scrubbers to remove solvent vapors from the exhaust gases.

The scrubbers use a chemical solution to absorb the solvent vapors, converting them into a non - volatile form that can be safely disposed of. This helps to reduce the emissions of volatile organic compounds (VOCs) into the atmosphere, which is beneficial for both the local environment and the health of the surrounding communities.

5. Overcoming Challenges
