OUR SLOGAN: REDUCE REUSE RECYCLE COMPOST

ZERO WASTE ‘Zero waste is a logical planning approach incorporating principles of effective human and material resource utilization to avoid the conversion of discards into waste – an inefficient form – in a manner that revitalizes the local economy.’ Making sure that you keep materials within the economic system Using less, re-using, recycling, composting

MOVING TO ZERO WASTE The top of the hierarchy is the priority: 1) Prevention 2) Reuse 3) Recycling 4) Composting

Nature of Waste Any bio degradable discards can be composted. It is good to avoid wood, coconut shells. Use saw dust, rice husk to maintain carbon – nitrogen ratio and to help aeration Size of waste particles Size of waste particles and speed of composting inversely related. smaller the particle size, faster the composting. Limit the maximum size to 5 cm. Humidity High humidity will lead to stinking and low humidity will stop composting. Maintain 40% -55% humidity Aeration To avoid stinking of compost ensure good aeration. use dry leaves, saw dust, rice husk etc to breath more air into compost to speed up the composting. Micro organisms To avail the micro organisms which will boos the composting process, sprinkle the compost with fresh cow dung diluted in water. Alternately spoiled curd, curries etc can be used. Temperature Vermi compost needs temperature between 20 – 30. Windrow composting may have temperature up to 60 ConsistencyBe consistent in terms of frequency and quantity of discards fed to a composting facility. never do shock loading Care to be taken in Composting and Vermi Composting
