Merci et au revoir, Claire!

‘Earth Citizen’ Claire Rao

Guitar strings, candle waste, broken bangles…

These are the things, among many other, that environmental activist Claire Rao has currently listed out as her top priorities that need urgent sorting-out and has been doing everything possible to make sure they reach proper recycling destinations. This has to happen before she herself lands in France, her home country, after over a decade of life lived here in Bangalore within what she calls, “our ecological limits”. Continue reading

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

This couldn’t have gotten better for those who have been trying to decentralise waste management in Bengaluru and championing composting as the best way to recycle wet waste in the city faced with unprecedented landfill crisis. At least now they can draw support from the US—so far known for its highest per capita garbage generation—for its fantastic composting mandates in many cities and push their cause forward saying, “Yes, we can!” 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.

Composting is a highly intricate process. The standard procedure takes anything between 30-45 days depending on the accelerators involved. A whole lot of work has to be done by different strains of bacteria and fungi to transform the organic material into compost. Although reams can be written about this beautiful process without which life is impossible on this planet, here’s just the gist of it. Continue reading

Sudh-Labh aerobic digesterNo major infrastructure, no fancy paraphernalia and no high-sounding claims.

For my case study, the destination was Sovereign Park, Basavanagudi. It’s a 23-year old, 40-unit apartment which does efficient segregation at source. It has outsourced secondary processing of dry waste to Sudh-Labh. They chose the same firm to compost their wet waste sometime in August. Continue reading

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.
