Last week I had bought some "organic manure" from a temple at Jayanagar, which they said was made out of kitchen waste and dry leaves in the temple premises. While applying the manure to plants, I noticed that there are numerous tiny shreds of plastic in the manure - like pieces of a biscuit packet, bubble wrap, a small chunk of thermocol, and so on. I thought of various methods to get rid of these, like pouring water over the manure kept in a bucket, etc., but could not find anything that is foolproof and easy.
A few weeks back, I had attended a small workshop at Bhoomi College, where I observed them making manure in a large scale. Dry leaves are a key ingredients for this process. They get these leaves from their campus itself, or from other places. And if we look into the piles of leaves they have accumulated there, we can always see several plastic things - chips packets, toffee-wrappers, etc. - It is not unexpected, but it is such a tedious job to remove these things before adding the leaves to the compost system. And we can never be 100% sure of making the compost plastic-free.
At our home, we make compost out of our kitchen waste. Not more than a small bucket of waste is generated each day, so it is not so difficult for me to take some extra care to remove all sort of plastic or non-decomposable things from the waste before dumping it in the composter; But after a few months when we take out the mature compost for gardening, I always end up seeing something or the other which had escaped me - like a sticker on the apple skin, for example.
It is scary to see plastic becoming such an integral and unavoidable part of our lives, even at a micro level.
