To find out if waste to energy plans are already used in Mumbai, we got in touch with an engineer from the solid waste management of the Municipal Corporation of Greater Mumbai (MCGM). He told us that in Deonar (an area with a notoriously large dumping ground) a biogas generator had recently begun to convert biodegradable waste to energy for a local hospital.

The process begins with the segregation of the waste to ensure the waste that is used in completely biodegradable (fragments of plastics and glass are sent to a dumping ground). Once segregated the waste is put into a liquefier.

Cities Worldwide Seek to Produce Recycled Energy

Reblogged from Flow with Silent Majesty:

By Tae-jun Kang  Toonari Post

In the last two years, a new technology that produces energy from waste has become popular in European and Asian countries, such as Korea and Japan.

Korea’s Incheon city is currently running a facility that produces fuel from residential wastes. It gets rid of combustible wastes first, and makes Refuse Derived Fuel (RDF) by compressing the rest of the waste.

Public transportation like subway or buses in Sweden’s Hammarby sjostad city are running by 100 percent recycled energy. Hammarby sjostad is known as “the city with zero carbon emission.” It is easy to spot people putting bio-gas in their vehicles at every gas stations in Hammarby sjostad city.

Dairy powers itself with cow poop -- including 42 tractor-trailers

Reblogged from Eideard:

Here at one of the largest dairy farms in the country, electricity generated using an endless supply of manure runs the equipment to milk around 30,000 cows three times a day.

For years, the farm has used livestock waste to create enough natural gas to power 10 barns, a cheese factory, a cafe, a gift shop and a maze of child-friendly exhibits about the world of dairy, including a 3D movie theater.

The farm is now turning the extra manure into fuel for its delivery trucks, powering 42 tractor-trailers that make daily runs to raw milk processing plants in Indiana, Kentucky and Tennessee.

Eat your leftovers

Reblogged from Energy, Technology, & Policy:

Americans throw away about 30% of all food produced domestically each year, and since at least 8% of the U.S. energy budget goes towards bringing food to tables across the country, energy waste is closely tied to food waste [1]. In fact, all of that wasted food equates to about 350 million barrels of oil per year [1].

The energy embedded in food waste comes from many sectors of the food industry: production, transportation, storage, and preparation.

Rather than sitting in a landfill, organic wastes such as food leftovers are put into anaerobic digesters that produce biogas rich in methane. This biogas can be used as fuel for heat and power generation, and the stuff that’s leftover can be used as composting material.

Environment and the Plasma Gasification of Garbage

Reblogged from The Discordant:

I wanted to bring to your attention a very interesting article that I read on the New York Times. The link is: Garbage Plasma Gasification.

It was a while ago when I read it, but didn't have time to write about it! So here it is:

The first thing I saw was the word “Garbage”… I didn't really give much attention to it because even though it is something really important, and that people should be aware of, I already know what most articles usually say about it.

Campania: The land of smoke and fire

Reblogged from In the Shadow of Vesuvius:

Garbage and Campania have a long sordid history together. With over 5.8 million people living in the region it shouldn't be surprising that they have trouble disposing of their waste. Naples is the largest city in Campania but the smallest province. With a population of 3,175,010 people and a population density of 2,625.9 people/sq. km it probably has the most difficulty with ridding itself of trash but also manages to keep the streets relatively clean* considering.

In Delhi, waste generates power — and debate

Reblogged from Panchabuta-Renewable Energy & Cleantech in India:

According to reports, by the end of this year, Delhi will have its second waste-to-energy plant generating electricity at the landfill near Ghazipur. A similar plant, Timarpur Okhla Waste to Energy plant, sited in the vicinity of a residential colony and a hospital, has started generation since the beginning of this year.

The Delhi government is buoyant that it has finally found a solution to tackling the ever-increasing piles of waste.

Waste management in Stockholm

Reblogged from Misc. on land use planning (with a bias on Copenhagen):

I just came across an article in "City, Culture and Society", dealing with Urban growth and waste management optimization in Stockholm and Adelaide. In Figure 2 in the results section the authors show a comparison of waste management systems in the two cities. However, for Stockholm they present only national data, assuming that this is also representative for the capital.

Municipal solid Waste to Energy - Are we doing enough?

Reblogged from Energy Matters:

Brief Introduction: There have been  lots of  reports from all over the world about utilization of municipal solid waste(MSW) for conversion to energy. In India too, we have been talking and discussing about segregation of household waste to enable subsequent processing activities. But it has not taken off in any significant way due to a number of reasons. In the next couple of posts I intend to summarize the approaches followed worldwide along with Technology options available.

Waste to Energy using plasma technology

Reblogged from Richard J Lafferty:

Advanced Plasma Power (APP), a UK based technology company, has developed an internationally patented waste-to-energy process called Gasplasma®.

Gasplasma® is a three stage process which converts Refuse Derived Fuel (RDF), made from household waste, into a hydrogen-rich synthesis gas (syngas) that can be used directly in gas engines to generate energy.

Advanced Plasma Power claims that the Gasplamsa® process is be highly efficient converting 98% of the incoming waste into energy while the remaining 2% is sent to landfill.

Waste to Energy

Reblogged from Melting Coal:

• 

Urban India produces 55 million tones of municipal solid waste and 38 billion litres of sewage annually. Further, large amounts of waste are produced by industries.

Waste generation in India is growing at a very fast pace and is expected to rise rapidly in the future. This has mainly been due to industrialization, increase in living standards and urbanization. This waste needs to be contained.
