BIOTECH, India, Turning food waste into biogas

http://www.youtube.com/watch?v=LrtINiLgNKY&feature=related

In Kerala, India a company called BIOTECH is running a food-waste-to-energy enterprise:

"BIOTECH has succeeded in tackling the problem of the dumping of food waste in the streets of Kerala through the installation of biogas plants that use the food waste to produce gas for cooking and, in some cases, electricity for lighting; the residue serves as a fertiliser. To date BIOTECH has built and installed an impressive 12,000 domestic plants (160 of which also use human waste from latrines to avoid contamination of ground water), 220 institutional plants and 17 municipal plants that use waste from markets to power generators. The disposal of food waste and the production of clean energy are not the only benefits of BIOTECH's scheme. The plants also replace the equivalent of about 3.7 tonnes/day of LPG and diesel which in turn results in the saving of about 3,700 tonnes/year of CO2, with further savings from the reduction in methane production as a result of the uncontrolled decomposition of waste, and from the transport of LPG."

"Thousands of charities and non-governmental agencies do development work in Africa, spending billions of dollars trying to make the continent a better place. There is a vigorous international debate over such assistance. While some projects claim success that provides new opportunities, critics contend that development money often does little good and can make matters worse. On a visit to Ethiopia's remote Afar region, correspondent Peter Heinlein found a development group that found success where others failed by 'following the clouds'."

The Intricacies of the Biosand Water Filter

The BioSand Water Filter is an adaptation of slow-sand filtration that is designed for use by families at the household level. This award-winning water filtration technology was developed by Dr. David Manz, a former University of Calgary professor.

The filters are a proven, effective, and inexpensive technology. From start to finish the filters can be constructed in roughly 10 days, at an average cost of $100, which covers the raw materials, construction, transportation, supervision, training for the family in filter maintenance and personal hygiene, as well as monitoring and evaluation.

The filter removes organisms responsible for diseases spread by water, such as cholera, typhoid fever, and amoebic dysentery. The filter also strains out particles causing cloudiness, and much of the organic matter responsible for taste, colour, and odour.

Truly Amazing Advanced Solar Cell from Israel

http://www.homemadepowerplant.com/?ho... Professor David Faiman, Head of the Ben-Gurion National Solar Energy Research Center and developer of a new solar cell that can produce over one thousand times more electric power than a conventional photovoltaic or PV, states, 'The achievement is that we separate out the collection function of a photovoltaic cell to the light conversion to electricity function. When we collect the light, instead of using a huge area of solar cells, we use an equal area of cheap glass mirrors and they are curved in such a way as to concentrate the light onto a very small solar cell, the size of just one cell, and in this way you concentrate the light a thousand times and you can get a thousand times more power out of a small cell.' This is truly an amazing development with several practical applications.

Smog-Eating Cement

"Take ordinary cement. Mix in an agent called a photo-catalyzer (titanium dioxide, if you really want to know), which speeds up the natural process that breaks down smog into its component parts. Now start paving things with the stuff. That's what they're doing in Segrate, an Italian town near Milan. The smog-eating cement is called TX Active, and the Italian firm Italcementi spent 10 years developing it. Now there's a busy street in Segrate that's covered with it, and Italcementi claims it has reduced nitric oxides in the area by as much as 60%. Bonus: buildings made with TX Active stay cleaner too." - TIME Magazine, TIME's Best Inventions of 2008

Constructing an ecosan toilet -- A film from UNICEF

Ecological Sanitation is an important new approach to sanitation, which is truly sustainable. It uses almost no water in its operation, and human waste products are used as fertilizer. So three major objectives are achieved:
-- saving on water, a critically scarce resource
-- non-pollution of the environment by human waste, a major cause of disease and loss of human life
-- 'closing the nutrient cycle' : the nutrients (primarily Nitrogen, Phosphorus, Potassium, and carbon matter) in our excreta goes back into the soil for re-use by plants. Instead of a one-way process where chemicals are mined and used for each crop produced, the same chemicals are returned to the soil for reuse.

This movie was created by UNICEF

BSP Biogas Sector Partnership, Nepal, Domestic biogas - Ashden Award winner

This video can be downloaded here: http://www.ashdenawards.org/winners/bsp BSP won an Ashden Award for Sustainable Energy in 2005. To find out more visit the link above and check out the Ashden Awards Blog http://ashdenawards.blogspot.com

The Biogas Sector Partnership (BSP) in Nepal managed the installation of over 124,000 domestic biogas plants in Nepal between 1992 and 2005. The plants use cattle manure to provide biogas for cooking and lighting. In addition, about 75% of the plants incorporate toilets.

About 80% of the 4.2 million households in Nepal use fuelwood, cattle-dung cakes and agricultural residues for cooking, and kerosene for lighting. Demand for fuelwood substantially exceeds the rate of regrowth, and this is leading to degradation of the land and damage to vital watersheds. Cooking indoors over open fires, and lighting with kerosene, gives dangerous exposure to air pollutants and a high risk of fire, particularly for women and young children who spend much of their time indoors. In addition, women and girls have the drudgery of collecting fuelwood, which typically takes three hours each day.

The Ashden judges commended this project for the many benefits which it provides. The biogas plants replace nearly all the use of fuelwood, and make cooking easier, cleaner and safer. In 20% of houses biogas provides safer lighting as well. This saving of unsustainable fuelwood use also reduces carbon dioxide emissions. The provision of toilets improves sanitation; and the effluent from the biogas plant is a valuable organic compost.

The use of cattle dung to generate biogas is well known in the Indian subcontinent, but in no other place has it been used with such success as in Nepal. The scale of the programme is remarkable. Biogas already serves about one million people (4% of the population of Nepal), and the biogas sector provides about 11,000 permanent jobs in the country. If anyone needed to be convinced that 'small scale can be big' then they need look no further! The Ashden judges also recognised the excellent collaboration between different organisations (BSP, government, construction companies, donors, finance organisations) in order to achieve such outstanding results.

Shaanxi Mothers, China, Domestic biogas for cooking & light - Ashden Award winner

This video can be downloaded here: http://www.ashdenawards.org/winners/s... Shaanxi Mothers won an Ashden Award for Sustainable Energy in 2006. To find out more visit the link above and check out the Ashden Awards Blog http://ashdenawards.blogspot.com

The Shaanxi Mothers' Environmental Protection Volunteer Association (Shaanxi Mothers) is led by its founder Mrs Wang Mingying. It has installed 1,294 biogas plants in rural farming households in the Shaanxi Province of China since 1999. The plants produce biogas from pig and human waste.

The extensive use of wood and coal that has helped to fuel China's rapid economic growth has led to serious environmental damage. In Shaanxi Province (west China), soil erosion on the hillsides is widespread and springtime flow in the rivers has diminished to a fraction of the 'normal' flow. Erosion leads to dust storms and poor outdoor air quality. The use of coal and wood on open fires produces significant pollution. Faced with these problems, the Chinese Government has restricted tree-felling and ordered the re-forestation of the terraced hillsides. Farmers are paid to plant trees and ensure that they survive, and are encouraged to keep pigs. Subsidies are provided to encourage the use of biogas.

Shaanxi Mothers promotes the use of biogas plants connected to the pigsties. These plants provide clean fuel for cooking and lighting, improve sanitation and hygiene and help prevent further environmental degradation. The solid residue from the plants is a valuable fertiliser. Users pay about one third of the cost of the plant which can be covered by the savings they make on fuel and fertiliser within one to two years. Subsidies from the government and Shaanxi Mothers provide the remainder of the cost.

The Ashden Award to the Shaanxi Mothers' Environmental Protection Volunteer Association recognises the tremendous commitment of a small volunteer organisation in bringing the health and environmental benefits of biogas to rural communities in China.

BIOTECH has succeeded in tackling the problem of the dumping of food waste in the streets of Kerala through the installation of biogas plants that use the food waste to produce gas for cooking and, in some cases, electricity for lighting; the residue serves as a fertiliser. To date BIOTECH has built and installed an impressive 12,000 domestic plants (160 of which also use human waste from latrines to avoid contamination of ground water), 220 institutional plants and 17 municipal plants that use waste from markets to power generators. The disposal of food waste and the production of clean energy are not the only benefits of BIOTECH's scheme. The plants also replace the equivalent of about 3.7 tonnes/day of LPG and diesel which in turn results in the saving of about 3,700 tonnes/year of CO2, with further savings from the reduction in methane production as a result of the uncontrolled decomposition of waste, and from the transport of LPG.

Wood-Gas Stove

This is a video of how to make a wood gas stove. A wood gas stove uses to stages of combustion. Stage 1 converts the wood to a gas, and stage 2 combustion the gas with the help of addition high temperature oxygen (or air) inlet near the gas combustion zone. The gas combustion zone is above the wood combustion zone.

Note, in the video, the two sets of vent holes—one set at the bottom of the outer (bean) can and one set at the top of the inner (soup) can. The bottom vent holes inlet air for both stages of combustion; a fraction of the inlet air passes directly into the bottom of the inner can and is used for combustion of the wood (stage 1), while the reaming fraction of the inlet air is heated as it passes up between the walls of inner and out cans, and finally through the top vent hole of the inner can. This is the high temperature air is what drives the stage 2 combustion process.

Some models use a small fan to “force” inlet air. Wood-gasification is one of the cleanest forms of combustion because it not only combusts the wood, but it subsequently combusts the gas produced from the initial combustion of the wood. This gas usually contains several pollutants, so when the gas is combusted, many of the pollutants get destroyed. Also, these stoves produce extremely high temperatures and are therefore very efficient.

Commonly referred to as wood gasifiers or wood-gas stoves.
