Waste Management

Waste Management

Sustainable practices for a cleaner, greener campus environment.

This indicator addresses waste production and disposal of different wastes like paper, food, plastic, biodegradable, construction, glass, dust etc. Furthermore, solid waste often includes wasted material resources that could otherwise be channeled into better service through recycling, repair, and reuse. Solid waste generation and management is a burning issue. Unscientific handling of solid waste can create threats to everyone. The survey focused on volume, type and current management practice of solid waste generated in the campus.

Liquid Waste Management

They have a Mini RO plant in all the blocks which is easily access to all the students & staffs to provide water for drinking and Cooking Purpose in Mess & Canteen.

Sewage Treatment Plant (STP)

Water is the basic necessity of life used for many purposes. So, recycling water is necessary. Considering this in our mind, SVCET have established a Sewage treatment plant inside the campus. The treated water is utilized properly for watering the plants throughout the campus and also for irrigation purposes.

Working Principle of STP

The Sewage water (containing bathroom and kitchen waste) from entire college as well as the hostel buildings are received through the underground pipe lines. It is passed through grid chamber, bar screen chamber and degreasing chamber. In the grid chamber heavy density materials like sand are removed. In the bar screen chamber floating material like leaves are separated. When the Sewage is passed through degreasing tank the floating greasy (Oily substances) materials are scrubbed away from the degreasing tank. Then the Sewage is transferred to collection tank. From the collection tank, Sewage is pumped to Bio reactor (Aeration tank). In the Bio reactor the Sewage is digested by aerobic bacteria using sewage as food materials. The above treated water is passed through the sludge settling tank. From here the sludge is separated and passed to Sludge drying beds. After drying the sludge, it is used as natural organic manure for our gardening. After removing the sludge, the water is collected in a separate collection tank. This water is then pumped to sand filter and activated carbon filter. In the sand filter suspended particles are removed. In the carbon filter, any odour in the treated water is removed. The filtered water is then collected in a sump. From this sump, the water is pumped to the entire college Gardens through overhead tank.

Initial Filtration

Sewage from college and hostel buildings passes through grid chambers and bar screens to remove heavy materials like sand and floating debris like leaves.

Degreasing & Aeration

Floating oily substances are scrubbed in the degreasing tank before the sewage is pumped into the Bio-reactor (Aeration tank) for digestion by aerobic bacteria.

Sludge Processing

Treated water passes through settling tanks. Separated sludge is dried and repurposed as natural organic manure for our campus gardens.

Final Purification

Water is pumped through sand and activated carbon filters to remove suspended particles and odors before being stored in a sump for irrigation.

Solid Waste Management

Waste generated from tree droppings and lawn management is major solid waste generated in the campus. Separate dustbins are provided for Bio-degradable and Plastic waste in order to segregate them at the source itself. Single sided used papers are reused for writing and printing in all the departments to minimize the usage of papers. Important and confidential reports/ papers are sent for pulping and recycling after completion of their preservation period.

Chemical waste generated in laboratories that are potentially hazardous are segregated. Very less plastic waste (0.1Kg/day) is generated by some departments, office, garden etc. Metal waste and wooden waste is stored and sent to authorized scrap agents for further processing. Glass bottles are reused in the laboratories. The college had Placed separate bins to collect biodegradable and non- biodegradable waste generated in the campus.

  • Single-sided papers are reused for printing and writing.
  • Chemical wastes from labs are strictly segregated.
  • Metal and wood scrap are sent to authorized agents.
  • Glass bottles are reused within laboratory settings.
Sustainability Goal

By minimizing paper usage and maximizing recycling, we reduce our municipal footprint to approximately 0.1Kg/day per department.
