India produces 540 million tones of crop & plant residues per annum
India produces 540 million tonnes of crop and plantation residues every year, a large portion of which is either wasted or used inefficiently. Estimates show that even with the present use of these residues and by using only the surplus biomass materials, estimated at 150 million tonnes, about 17,000MW of distributed power could be generated, which is almost 15 per cent of existing installed power capacity. - Read More

Waste to ethanol using gravity pressure vessel technology
In the gravity pressure vessel system, natural forces gravity and underground heat are used to convert waste into sugars, which are then fermented into ethanol or butanol. - Read More

Urine is liquid gold!
Urine makes up less than 1 percent of all waste water in developed countries, but contains a huge proportion of the nitrogen and phosphorus. Those nutrients are essential to agriculture but harmful in water bodies, and removing them is the most energy-intensive part of treating waste water. And since urine is almost sterile, it can be used as fertilizer with little to no treatment. - Read More

200 million farmers use untreated human waste in fields
Nearly 200 million farmers in China, India, Vietnam, Africa, Latin America harvest grains/vegetables from fields that use untreated human waste. Most of these draw irrigation water from local rivers or lakes. Unlike developed cities, these areas lack advanced water-treatment facilities, and rivers effectively become sewers. Farmers risk absorbing disease-causing bacteria, & consumers who eat the produce raw and unwashed. Nearly 2.2 million die of diarrhea per year! What a biz opportunity! - Read More

Food waste to biopolymers
you'll continue to see the growth in food-waste diversion efforts?if people understand that food scraps, both pre- and post-consumer, are a resource that can be recovered and used as a feedstock for a process that's going to give them a useful product.

Garbage-to-fuel process using algae is explored
A island businessman says he can convert West Hawaii's trash into electricity and feed the emissions to native algae from which fuel oil can be extracted. The Natural Energy Laboratory of Hawaii Authority, which stands to benefit from the power, told him on Tuesday they're listening. - Read More

New Trash Riddance System Creates Energy and is Eco-friendly
A new conceptual trash riddance design claims to tackle one of our prime problems. The Electrolux appliance not only finds a good way to get rid of food waste, but it also has the potential to entirely replace LPG and is extremely eco-friendly. It is designed in a way that it immediately starts fermenting the load and creates methane that can be used as fuel for the gas range; the consequential waste is dried out by the appliance and composed in a tank at the bottom that can be disposed of later - Read More
