As the college premises is spread over an area of 51 acres 37 R, it is challenging to maintain the serenity of the campus.
The institute has accepted this challenge by developing its own mechanism for waste management. The civil department and campus development committee of the college deals with the issues related to maintenance.

• Dust bins for collection of solid waste are placed at suitable sites in the campus.
• All the biodegradable solid wastes generated in the campus is collected manually and transported with the help of tractor for its composting. The manure produced is used for the plants in the campus.
• Plants litter are regularly collected and used in vermi-composting unit.
• The biodegradable waste material collected from the mess is used for the production of bio-gas which in turn is used for cooking.

• Dust bins for collection of solid waste are placed at suitable sites in the campus.
• All the scrap material is collected and transported to the central workshop of PRES for
  further action.

• The hazardous waste from the laboratories like acids and alkalis are diluted with water
  and neutralized with weak alkalis'. Further, we have been practicing semi-micro and micro qualitative and quantitative analysis, therefore the wastage of chemicals is minimum.
• Volatile organic solvents used for extraction and synthesis are collected, distilled and reused.
• Exhausted cultures are autoclaved and discarded in the respective laboratories.
• College has installed a Sewage Treatment Plant (STP) to recycle the sewage water from the Science Building, Gymkhana, PG Building, Boys Hostels and Library Building.
• The recycled water is used for gardening and maintaining the lawns.
