With increase in the concern for the environment, many ways to recycle the waste produced by the humans have evolved and one of them being compost.
Compost is an organic matter that has been decomposed and recycled as a fertilizer and soil amendment. Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. It further undergoes decomposition in presence of worms and anaerobic bacteria which is used as a organic manure.
Thus produced naturally it contains all the important ingredients needed to soil and nourishes it well.
Americans are producing 25 million tons (approx) of waste every year. This consists of both compostable and non compostable waste.
Compostable waste include: green items, brown items, dead leaves, coffee and tea filter bags and etc.
Non compostable waste include: pet litter, meat and bones, dairy products etc which cannot be used in the compost as they take a lot of time to decompose.
