Campus Recycling of Wastes

Introduction

The Campus Recycling Programme was primarily visualized as an effort to stop land filling on the campus. for 30 years no waste had left the campus. The entire waste was being dumped in huge ravines within the campus. The Institute wanted to handle its waste in environment friendly ways. It wanted to integrate solid management techniques like recycling, composting and hygienic landfilling in conjuction with each other in order to meet their waste abatement goals. The solution of the Campus Recycling Programme has been to acknowledge the work of the recycling industry of Delhi and link our output to their raw material needs. The project was based on the belief that the community would support the effort by segregating their waste. Segregation at source increases the value of the recyclable products and also reduces the quantity of total waste put out by each household. The Campus Recycling Programme - the two Channel System The residents put their garbage in two bins at home. The food waste was put in one bin and the rest in the other bin. 60 Drop sites have been installed all over the campus. Each dropsite is a composite unit of one Bio bin and one Recycle bin. All residents are asked to deposit the food waste in the Bio bin and the others in the Recycle bin. All waste is tied in a plastic bag before placing in the bins. Some residents employ sweepers to put out their waste. In such cases the sweepers ensure that the separated waste is put in their respective bins. Some houses are provided with Composting Bins in their gardens. Waste from the DROP SITE is collected everyday between 9-11 AM by the Campus Recycling Programme (CRP) team in a rickshaw or a tempo. The waste is taken to the Collection Centre at the micro model complex. The waste arrives-it is unloaded and finely segregated. The food waste goes into making composting windrows. The other waste is sorted and bagged and sold to dealers who then sell to the recyclers. What cannot be directly sold is stored till a dealer for the same is established. for large items like old mattresses, rugs, cooler pads, old cloths etc. the CRP team runs a Saturday Pickup which operates within the campus and picks up these items from every household. All residents are given a list of products that go into the bio bin and the recycle bin. This is to avoid confusion at the throwing stage.
