This 24-hour composter was on fire, literally!

A simple human error resulted in this machine catching fire and damaging the roof of DSR Woodwinds apartment’s compost room six months ago. It seems beyond repair now and has been dumped in the parking lot. (Pics: SH)

This is an incident that unfolded at DSR Woodwinds apartment, Sarjapur Road. An automatic 24-hour machine given by the builder to compost kitchen waste caught fire when a staff member mistakenly switched on the machine after sundown. Within hours, the machine was spewing out flames and the roof got damaged. The smoke spread. The staff somehow managed to sneak into the compost room and put out the fire. Since then the machine, which comes loaded with promises of turning precious green waste into valuable compost, has been gathering dust in the community’s parking lot. (For more technical details on these machines, please read this post.)

Community composting: If it’s costlier & fancier, does it get better?

One of my Solid Waste Round Table Management (SWMRT) colleagues told me about an apartment which is getting ready to spend up to Rs 45 lakhs on a certain method for its in situ wet waste composting. In other cases, some companies which have succeeded in installing their 24-hour composting machines in some apartments at the cost of up to Rs 20 lakhs or more are laughing all the way to the bank.

Should a residential community invest so much in composting alone? Continue reading

Cassia block of Brigade Millennium in J P Nagar has its own unique steel bins system which has been producing one tonne of compost each month.

Bangalore’s roads run like tedious arguments. I had to meander my way around one such ‘argument’ recently by hitting the road at 7 am in Yelahanka to study a community composting method in an apartment located in J P Nagar.

Cassia Block is just like any other nestling in this mammoth condominium called Brigade Millennium. But it stands apart for its high eco quotient nurtured by its all-woman management committee. They have a very good waste and water management system in place and in fact, the residents have stepped out of their threshold, cleaned up a spot just out of their periphery, planted a line of trees and have even set aside some space for vermi-composting right there.

Now, that definitely sets the tone for this write-up, doesn’t it? 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

With 300 sun-blessed days in a year, any solar solution makes absolute sense in India, doesn’t it? When it comes to community composting, how about a composter that relies only on sunlight to get things going?

Marigold solar composter is a brainchild of Bengaluru-based Ravindra Karnad, IIT-Kanpur, Prudent Eco Systems Private Limited. Continue reading

Fully automatic composting machines: Let the buyer beware

Just Google “fully automatic composting machines”, a number of companies making out-of-the-world claims pop up instantly. Among them, “composting in 24 hours” is the most common.

I have been approached by a few vendors in Bengaluru to write about their products as a community composting method. When I met them, each vendor made different claims although all of them ran on similar technology. Continue reading

Will San Francisco, Seattle & New York shame Bengaluru into composting?

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
