Unlike many western countries, Indian consumers waste remarkably little food, as a use is found for nearly all left-overs and food scraps. However, this doesn’t mean that there’s no waste, and Pune, a four million person city three hours southeast of Mumbai, is implementing an innovative initiative to change that.
Meet Mr. Santosh Gondhalekar, an engineer, energy expert, and founder of a bio-energy start-up company, Gangotree Eco Technologies. Pune is on its way to being India’s first waste-free city.
Each day, Pune generates about 1,400 tons of waste – 800 tons of organic waste and 600 tons of dry waste (e.g., paper, plastic, glass, and metals). In addition to the city’s municipal waste collection agency, Pune also has a sizable waste-picking community, with over 2,000 individuals who work full time as part of a cooperative to collect and sort the city’s waste. Nearly all of the dry waste has value so it gets sorted out by the waste pickers before being sold to recycling companies. The organic waste remains, and historically has been placed in a municipal dump.
Just a few years ago, the Pune Municipal Corporation engaged in a number of public-private partnerships to extract value from this organic waste. Here’s how it works: the city puts up the required capital to build bio-digestion facilities that can convert organic waste to electricity. Private companies then operate the facilities, selling the electricity back to the city to be used to power street lights. Excluding the upfront capital costs, the operation is profitable for the private firms. And for the time being, the city is willing to invest the capital, essentially subsidizing the projects, as they reduce the city’s waste burden, lowering the cost of maintaining municipal dump sites.
Currently 10 of these bio-digestion plants are operational, each converting five tons of organic waste to electricity every day.
How it works ? The Process:
Each morning, city trucks pick up organic waste, primarily from the city’s hotels, and deliver it to the bio-digestion facilities. The hotels are required by law to pay a fee for this service, which generally covers the transportation costs. Once the waste arrives on site, waste pickers sort it to ensure that it’s 100% organic as other inputs could disrupt the bio-digestion process. The waste, or feed stock, is then chopped up and put into the bio-digester, where bacteria converts it to methane and compost. At the end of the day, the gas is scrubbed to convert it to 99% methane, and then burned in a generator that creates electricity. The compost is given to local farmers.
So far the initiative has been very successful, and there are plans to have 20 additional plants operational by the end of 2012. Pune has 144 city wards, and if each ward had its own bio-digester, the city would be able to extract electricity from all of its organic waste.
Mr. Gondhalekar has been involved with the planning and execution of these projects, and showed his enthusiasm for the initiative’s success. However, his company, Gangotree Eco Technologies, is working a new project he finds even more promising. His plan is to convert municipal organic waste to what he calls green coal.
 Use clay Ganesha idols
Only Ganesha idols made out of clay should be used as they dissolve in water easily.
 Use natural dyes & colours
If a colourful Ganesha idol is being purchased during the festive season, then it should be painted with natural dyes. Dyes are available in many places across the state.
 Stop immersing, start exchanging!
The immersion of idols pollutes water bodies. To reduce pollution, Ganesha mandalis could retain the same idols and exchange them with other organisations every year. This will ensure the usage of existing idols without polluting the water. Such a trend is already taking place in Pune and Mumbai.
 Immerse idol in bucket of water
Instead of using drinking water, the people should immerse idols in pushkarnis and other places specified by district administrations. Immerse idols in buckets of water. Before the immersion, remove all decorative items, like flowers, plastic, garlands etc. Do not immerse idols in rivers, lakes and wells. Avoid using plastic decorative items. Use natural leaves, plants and flowers.
 Avoid bursting Fire Crackers
People should control the use of crackers which cause noise, air pollution and generate solid waste. Avoid blaring music from loudspeakers or organising orchestras. Sound pollution causes extreme discomfort to the elderly, patients and infants.
Three years after Mahindra group acquired Bangalore-based electric car maker Reva, the company launched its first electric car ‘e2o’ priced at Rs 5.96 lakh (on road Delhi, after state subsidy).
The group also said it has plans to extend the electric mobility technology to its two-wheelers, while seeking support from the central government for pushing eco-friendly vehicles.
The Mahindra e2o utilises Lithium ion batteries and offers a 100 km drive range to its owner which is a very feasible distance for urban use. In terms of recharging, the electric car can be re-charged through any 15 amp plug point along with the Sun2Car option that utilises solar power technology. While the e2o does not have active competition in the market, the upcoming Nissan Leaf may be able to give it a run for its money. Additionally, vehicles like Hyundai i10, Maruti Ritz and Swift will also offer competition to the e2o as they are a part of the growing B segment hatchback portfolio.
Commenting on the market expansion plans for the e2o, Mahindra & Mahindra President (Automotive and Farm Equipment Sectors) Pawan Goenka said: “We will be launching it in eight other cities over the next three to four weeks. The prices will vary as it would depend on how much subsidy state governments will give to the electric car.”
In Delhi, the government has given a total of 29 per cent subsidy on the electric car as a result of which the company has been able to sell it at an on-road price of Rs 5.96 lakh, he said, adding it would be more expensive in other cities.
The ‘e2o’ will also be launched in Mumbai, Bangalore, Pune, Ahmedabad, Hyderabad, Chandigarh, Pune and Kochi.
