Community Composting

Community Composting is one of the most sustainable ways of managing organic waste by a group or community of people. It is a rewarding activity that makes sense of valuable resources which are often considered as "garbage" or "rubbish".

Why Compost?

Tons of organic waste generated can be converted into a valuable manure which you can utilize to grow your own organic food in your own organic garden or farm.

Your dustbin will smell much sweeter as the organic waste is segregated and is utilized for compost making; sorting the recyclable waste becomes a lot easier.

Composting helps to reduce the amount of waste being sent to the landfills thus reducing the pollution from sites.

When heaps of compost is created it encourages and improves sustainability of wildlife such as grass, worms, snakes, hedgehogs and many other wildlife creatures. These creatures help enhance the natural recycling process of the soil.

Now, lets talk about the community composting options:

Aaditi

The mother of all gods

A hymn in the Rig Veda mentions that Aaditi is the progenitor of the human race. The hymn talks about life coming out of Bhu(earth), and then going back to it, signalling the cycle of life and death and the fact that matter is recycled again and again. Our community composting solution is an ode to Aaditi.

    • Alternative to Stonesoup brick: 1Litre cow urine or 10 litre cow dung slurry (Once in 3 months ideal)
    • To layer with kitchen waste or not. Garden leaves only does not have a nitrogen source. possible sources are flowers. (Other options fruit and vegetable peels, coffee tea grounds - these have to be mixed with SCMB to avoid fruit flies and smell.)
    • Bottom plate and legs or cement blocks - bottom plate can be an FRP sheet with holes and not made of metal. both options are work well.
    • Only leaf waste - After 6 months the output will be leaf mulch and can be used as mulch around the plants / trees. 
    • Leaf waste and SCMB - After 4 months it can be used as compost and also used as potting mix
    • Leaf waste and cow dung - After 4 months it can be used as compost and also used as potting mix
    • Shredding - can accelerate composting cycle time. Also improves the air circulation of the aerobic pile.
