Global agriculture wastes 60%,or 1 500 trillion litres, of the 2, 500 trillion litres of water it uses each year, according to the WWF.

The waste is mainly down to inefficient irrigation systems. But better managed, it could mean more water resources for other basics like drinking, hygiene and cooking.

Because biochar can be produced from various waste biomass including agricultural residues this new technology provides an alternative

and has been shown to cause cancer. ecause biochar can be produced from various waste biomass including agricultural residues this new technology provides an alternative and cost-effective way for arsenic removalsays Bin Gao associate professor of agricultural

to produce electricity as they digest plant and animal waste. Scientists hope the icrobial batterycan be used in places such as sewage treatment plants

Michael Koenig, Honda Smart home project leader, said that converting DC to AC wastes energy, so this is a DC-based project.

The small amount of solid waste that comes out on the other end is no longer poop

Gates himself describes the waste-to-water process on his Gates Notes blog: I watched the piles of feces go up the conveyer belt and drop into a large bin.

that machine will be able to handle the waste of 100, 000 people and, from that, produce 86,000 liters of clean water on a daily basis while also generating a net 250 kilowatts of electricity.

and a shoebox-size module (for base stations) based on nearly a decade of MIT research to essentially switch gears to adjust voltage supply to power amplifiers as needed cutting the waste.

But a more cyclical approach where waste is used as an energy source could provide higher profit yields

where the waste of industry is recycled to create energy and value much like in natural ecosystems. n a natural ecosystem,

there really is no such thing as waste, Silver says. t just another resource. l

so running the Cannock Sainsbury's actually requires waste from several.)From the depot, a waste management company called Biffa will truck the waste to its Cannock plant.

What happens at Biffa's Cannock anaerobic digester is "what happens inside a cow's stomach after dinner,

It produces some solid and liquid wastes called the digestate. Some of the digestate can be used as fertilizer,

and a significant amount of waste is generated. Professor Kobayashi's application of flow chemistry techniques to the production of fine chemicals using heterogeneous catalysts has resulted in simple method to synthesize (R)

This simple and affordable alternative to ground-mounted systems is particularly suitable for water-intensive industries who cannot afford to waste either land or water.

#Scientists create food powder from waste, increasing shelf life from two weeks to two years Kent Ngo, Vita Jarolimkova,

we produce more PLA with less waste and without using metals. In addition, the production process is cheaper,

as that gradually gets absorbed by the body as harmless waste). The scaffolds could also be used for other cell types,

The Harvest phone case grabs the power your phone wastes and puts it back into the battery.

#Biodiesel made easier and cleaner with waste-recycling catalyst (Nanowerk News) Researchers at Cardiff University have devised a way of increasing the yield of biodiesel by using the waste left over from its production process.

which waste is dealt with, and seriously improve the quality of life by reducing carbon emissions from fossil fuels and encourage efficient use of resources."

There's also the issue of how to deal with the waste produced from the process.

#Biochar from manure waste enhances soils Researchers at Universidad Politécnica de Madrid have obtained biochar using manure waste,

Biochar, a material obtained after thermal treatment of this waste through pyrolysis, is an organic fertilizer that applied in soils

but also represents a significant reduction of CO2 EMISSIONS compared to the direct application of manure waste on soils.

and using raw materials from the waste we generate are some of the environmental challenge that we face today.

This waste contains fertilizers, and its production has increased over the last years because of intensive farming and has been used traditionally in soils as an organic amendment.

Pyrolysis of manure waste can drastically reduce CO2 EMISSIONS compared to the direct application of manure waste to soils.

which waste is dealt with, and seriously improve the quality of life by reducing carbon emissions from fossil fuels and encourage efficient use of resources."

It was not easy to explain that waste or even human feces can be recycled. The KIT scientists also conceived seminars for the operators of the plants and information material and instructions for the population.

The project is part of the Gates Foundation's Reinvent the Toilet Challenge an effort to develop a next-generation toilet that can be used to disinfect liquid and solid waste

and effectively carbonize solid waste. While the current toilet has been created to serve four to six people a day a larger facility that could serve several households simultaneously is under design with the target of meeting a cost level of five cents a day per user set by the Gates Foundation.

On the upside, all that agricultural waste creates a solid biofuels pipeline. Forget the food-versus-fuel debate:

More biorefineries such as the Calgren plant could help California solve multiple challenges a boost in production of clean transport fuels, the reduction in agricultural waste and for local residents,

These permeable silicone beads could be sliced a-bread'breakthrough for CO2 capture--efficient easy-to-handle minimal waste

what stands to inspire a new generation to take advantage of energy inefficiency and waste. One major drawback to the technology is that its relatively slow to harvest energy,

Organizations are trying to recycle the waste or mine it for valuable resources like gold,

Instead of waiting until they're headed to the trashcan to clean up the waste, they're tackling the problem at the very start of the supply chain n

Then the volume flow in the plant can be doubled utilization of carbon from biomass will increase to nearly 100%and a large amount of usable waste heat will be produced by the catalyst (Ptg operation.

Since the waste in the wastewater (organic material) is consumed and thus removed, the water itself becomes purified,

we produce more PLA with less waste and without using metals. In addition, the production process is cheaper,

and agricultural waste that are fermented by genetically engineered microbes. lthough there are some additional technical challenges associated with using sugars derived entirely from biomass feedstocks like Miscanthus
