Pilot study on Garden waste management
About 10% of the areas in housing societies is for recreation purposes: gardens, playgrounds and parks. Garden waste forms about 12% of solid waste generated in the city. But in recent years there has been a lot of vertical development, where the landscape area per tenement has reduced. Hence, the requirement of treating garden waste has reduced.
Ninad Jog from College of Environmental Planning and Technology, Ahemdabad (CEPT) conducted a research on garden waste management under the guidance of the SI team. He studied the treatment methods for garden waste in housing colonies and carried out a pilot experiment at Shrirang housing colony in Pune. Garden waste from 26 plots of approx. 3000 sq ft each was collected and stored in a vermi-culture pit. The vermi-composting process was constantly monitored to assess the quality of the treated waste. The results showed that it took about 3 months to treat 3 brass of Garden waste in to fine quality manure. It also showed that the volume of waste was reduced by half after the composting process. The compost was later distributed in the nearby plots.
