About the Project:

Municipal Corporation Gurugram (MCG) along has partnered with Harit Recycler Association, a private operator in order to initiate decentralized composting at Nandi Dham goshala (cowshed) at Ashok Vihar, Phase III, Gurugram. The project was started in October, 2015. The area of Nandi Dham Goshala has been assigned by the MCG Wet waste collected from sectors 22 and 23 of Gurugram is used to produce organic manure. There are 55 aerobic composting pits at the goshala that are made of bricks. However, the base of the pits are devoid of bricks to maintain natural water flow. On an average 3 - 4 T of organic waste is received at the composting site daily. 7 - 8 pits are filled every day with organic waste. After 4 - 5 days, cow dung is added on the waste. It is then filled with another layer of fresh waste from top. During a one-month period, this cycle is repeated 4 - 5 times for the same pits. The mixture is then allowed to decompose for 40-50 days. After decomposition is complete the manure thus produced is dried and sieved and used by the Nagar Nigam. Apart from the aerobic composting pits, there are 3 deep anaerobic composting pits at the goshala of 10 feet X 10 feet size each. Each pit has the capacity of holding 20 T of wet waste. This process takes 3 - 4 months’ time to completely decompose the waste.While green bag is send to the Composting shed the blue bag is sent to Dry waste shed to the other end of the campus. The wet waste is mixed with garden waste and crushed using Chipy Chopy Organic Waste Crusher or Shredder, which are available in different capacities such as 1HP, 2HP, 3HP etc. Further, rinsing and dehydration of excess water, liquid or moisture from the waste is done through Easy Squeezy De-hydrator. The wet waste is mixed with dry leaf litter from their gardens and put in various canvas container Bins or Bags. The compost for use is ready in 20-30 days. The dry waste is taken by a waste collector/ recycler at a specified time once a day. The quarterly maintenance charges paid by each house hold for several services including Solid Waste Management Rs.5000 and the waste pickers and workers in the shed are paid their monthly remuneration from the collected maintenance charges only. The technology for composting plant was installed by Mr. Saurav Bardhan of Green Bandhu, a small start-up. Their technology is fully functional in the campus and is taken care of by the staff.
