We have quite a few individual home composting and also several large-scale composting solutions available in the market. But large bulk generators with 50 homes or above grabbed the focus of most of the emerging eco-innovators thus far, leaving the small apartment segment with 10-15 homes, or fewer, crying for attention.

In general, large complexes have many advantages stacked in their favour—mainly financial leeway to an extent and space set aside for processing waste. If not, they can carve out a corner on the terrace or basement to get going. I have seen this happening in several communities. Continue reading

A little bit of science on how composting happens

blog-compost

Ever wondered why an ice cream box frozen at subzero conditions goes stale and begins to smell bad? It’s actually the presence of anaerobes that thrive even at -2°C. Micro-organisms can be present at extreme temperatures: At -2 °C, and also at 122 °C.

Paired up to perform: Two Byobins is all it takes to process wet waste from 30 houses.

Two unassuming bins sit in a corner without any posters, scary timetables or paraphernalia around them. No muttering of a shredder. No hustle and bustle of an army of workers either. A few perforated plastic crates filled with the compost taken out of these bins have earthworms going about their business without giving two hoots to what the city is getting all worked up about.
