Interview with Manager of yelahanka waste segregating unit


Interview 2
Interview for decomposition / compost / waste management 

The BBMP is a state council that manages 30% of solid waste in Banaglore, India. They have divided the city into eight zones. One of them is Yelahenka, where I live. It has solid waste processing units, which I visited and then interviewed one of the managers in the waste processing unit.

Me. Can you explain the process of how waste is brought into these units?
H.P. The waste is put into plastic bags by households and kept outside each house in the morning, which undergoes a door to door collection starting at about 7 am by auto tippers and push carts. They all meet at a point near the bus station, where the waste gets put into a truck. The truck brings this solid waste into the first processing unit where the dry and wet (food) waste is segregated by the Pourakarmikas (cleaners). 

Me. Oh okay. So then after segregation from this unit, does it go to the waste processing units? 
H.P. Yes, exactly. We have 2 processing plants here for recycling plastics and metals etc. And in total in Bangalore, BBMP has setup a 15 ton capacity decentralized plants to process organic waste as well as recycle the plastic and metals etc.    

Me. Okay. How and where do you process organic waste then?
H.P. Well, the waste from Yelahanka goes to the one ton capacity aerobic composting unit at Maleshwaram market (West Zone). The technology is an organic waste convertor. 

Me. And how much of waste do you get daily?
H.P. Um well there is a mix of all types of waste from households as I told you it is not segregated at the source, so all waste is about 350 grams per day. Out of all that organic waste is about 50-80 grams average and Yelahanka's population is about 3 lakh people.

Me. But considering Bangalore is such a big city, and the Maleshwaram flower market, I am sure the organic waste is way more than one ton can process. Do you use any other way to process waste. 
H.P. Well, we do other organic process centers in the south parts of the city. And we have been able to manage most of the organic waste but the leftover is scientifically landfilled. However, as you might have heard of the Bangalore landfill crisis, our aim is to adopt a zero waste management policy and reduce landfilling by less that 10% this year. 

Me. Yes, landfill is a huge issue in Bangalore now. Can you elaborate on how you aim to adopt zero waste management policy?
H.P. Yes, we have quite a few plans for this. First, we plan to set four large processing plants using technologies such as aerobic composting, converting waste into energy, vermin compositing, biomethanization and scientific landfills that can process upto 1000 metric tones of solid waste every day.  Second, we are working on putting up more recycling plants. Third, we are currently using small quantities of plastic waste to construct roads but are coming up with solutions that make 100% waste generated roads. Further, we are developing technologies that convert plastic into diesel. This can be implemented in large scales and has great potential. 

Me. Oh those sound like great strategies. Thank you so much for you time. It was great and very insightful to the waste management in our city. Thank you so much. 
H.P. Smiles. Thank you.

Interview with Sarah Temple

I interviewed LCC's Sarah Temple on the 'Meet the tide' project which designed our current bin system. 'Meet the tide' is UAL's platform for students to engage in sustainable art and design, and is something which Sarah is involved in.

This is a condensed version of what she had to say:

"The bins were designed by a final year UAL student called Chris Morley who was discovered at his degree show, and asked to help create the branding for the 'meet the tide' project. This led to him creating the red and green bin system we have today. Although its interesting that a lot of people find the bins extremely ugly!
It's interesting that you talk about food waste and compost because there is actually a project in the making at the moment to build a sustainable 'colour garden' at LCC. A man named Gary Martin is in charge, and the idea is to grow things for their colour and to teach student about the natural dye process, using things like red onion etc.
There was also another group of LCC students a few years back who set up a project called 'food for good', where they would go round all the restaurants at the end of the day, and collect the leftover food, and take it homeless shelters.
Another place in London worth looking into is a Kings Cross Restaurant called Acorn House, and it claims to have 0% waste!
It sounds like a very interesting project and I hope you are able to get some good ideas!"

Some more versions of lightbulbs!!

Here are some more versions of lightbulbs I did using the banana just to see if I could make a better one, or we could use the original...
