Solid Waste Management

solid waste

All living organisms create waste, but humans create far more waste than other species. As much as the population increase, waste generation also become higher along with the population growth in the world. Improperly stored refuse cause health, safety and economic problems. To prevent damaging the Earth’s ecosystems and maintain a high quality of life for the planet’s inhabitants, it is essential to manage and store waste efficiently and safely.

Due to diverse nature of the activities of the University, a large amount of wastes are produced and collected, ranging from general wastes, recyclable materials and hazardous wastes. The Green Practices Committee has prepared a solid waste management plan to ensure all of these wastes are disposed responsibly, using appropriate strategies.

Habitat Management


Tree Planting And Habitat Enhancement Programs Are Being Carried Out To Increase The Greenery In The University Premises And To Attract Animals (E.G. Butterflies, Bees, Birds And Small Mammals).

  • Number Of Fruit Plants Planted During The Period Of January To July, 2015 – 158
  • Number Of Herbal Plants Planted During The Period Of January To July, 2015 – 60
  • Other Plants Planted From January To July 2015 – 300
  • Number Of Anthurium And Other Flowering Plants Maintained At The University Plant Nursery – 105
  • A Vegetable Cultivation Plots Are Maintained At The University Premises To Provide Food For Birds And Other Organisms.

Energy Management


Energy conservation is very important as an organization, as a country or as the whole world. It reduces the cost of living, reduces the consumption of resources, conserve energy sources for future generation and protect the environment.

Conservation of energy on the other hand a social responsibility. Energy management is the process of monitoring, controlling, and conserving energy. Therefore University of Kelaniya has inaugurated an energy management progrmme with a view to reduce energy waste and to reduce energy consumption.

As an initial step, an energy audit was conducted in 2014/2015 to monitor and evaluate the current energy consumption of the University. University meets its energy requirements mainly through grid electricity and diesel. The  average  monthly  electrical  energy  consumption  is  in  the  range  of  230,500kWh and the present average maximum monthly demand is in the range of 1,170 kVA. The average  monthly diesel  consumption  for  generators  is  in  the  range  of  1500L.  Hence, the university incurs nearly LKR 4.74 Million monthly for its energy requirements, at the existing electricity tariff and diesel price.

Rain Water Harvesting


Rain water harvesting is the method of using rain water for a useful work of our daily life. It includes, collecting and storing of rain water from rooftops using simple techniques such as tubs or tanks or more complex techniques such as underground check dams. University of Kelaniya also planning to introduce a rain water harvesting system to minimize the water wastage within the university and to get maximum use of rain water. Rain water collected in tanks will be used for composting gardening purposes. The installation of a rain water harvesting system at the Faculty of Commerce and Management was initiated in July 2015.

Waste Water Treatment

The main objective of waste water treatment is generally to allow human / industrial effluents to be disposed of without any danger to human health or damage to the natural environment.

Use of waste water for Irrigation is both disposal and utilization and is an effective form of wastewater disposal (as in slow-rate land treatment). However, some degree of treatment must normally be provided to raw municipal waste water before it uses for agricultural or landscape irrigation or for aquaculture. Therefore university has been implemented a waste water treatment plant to get maximum use from the waste water released from the university hostels and at the same time, a constructed Wetland is being managing from the treated waste water in Sri Pangarama Hostel.


Resource Consumption Reduction

  • GPC implemented a strategic plan to reduce “Resource Consumption”. Currently, E –minutes are proceeding in Financial Committee, Computer Committee, Web masters Committee. Total number of papers saved from E-meetings (from May to September) are 2410. Therefore Weight of paper savings from E- meetings (from May to September) are 12,508 g.
  • To reduce the paper wastage, a centralized photocopy system was started from mid of July, 2015 in the administrative building. It could reduce the paper wastage and expenses from about half.
  • To reduce the use of Plastic, a circular was released which stating the prohibition of issuing money for purchasing plastic water bottles for any purpose (Symposia, Workshop etc.) within the university.
