Or maybe someone could mine the Great Pacific Garbage Patch. Pearce says that it takes about 20 milk jugs to produce about 1 kilogram of plastic filament,
there's a little suction where the garbage goes. The astronauts can sit over that, so the crumbs will go right into the suction.
Because it's made from decomposing waste that would otherwise go back into the atmosphere, when it's converted to charcoal we can sequester that carbon in the ground.
In Beijing, turning Kung Pao Chicken into organic fertilizerbeijing--For a place which deals with tons of rotting garbage each day,
Abandoned chopsticks are shaken out of the garbage at Goldenway's Gaoancun plant. After rouge chopsticks
and other nonorganic waste are filtered out, the remaining waste is poured into vats heated at 80 degrees Celsius,
where it mixes with a specially manufactured enzyme. Ten hours later, the waste emerges as a powdery brown  coloured  fertilizer,
which the plant s designers say is ideal for growing organic fruit and vegetables. Food waste accounts for more than half of the nearly 20,000 tons of garbage Beijing generates daily, most
of which is buried underground. Beijinger s penchant for fried food means that the city s waste is surrounded by a layer of cooking oil,
The company sells its waste generated fertilizer to organic farms, answering a pressing need in China,
while water and carbon dioxide are the only waste products from the process, the firm's PR manager Yi Dan said.
The garbage takes 10 hours to decompose into fertilizer. Goldenway has opened eight similar plants across China.
 The company's secret is its garbage eating enzyme, developed in a lab in the Southern Chinese city of Chengdu, according to Yi.

RTI International received a $1. 3 million grant to fund the development of a self-contained toulet system disinfects liquid waste and turns solid waste into fuel or electricity through a biomass energy

Organic waste that creates methane is another focus of the company's sustainability initiatives; since 2005 the company has reduce its solid wate sent to landfill by 60 percent.

Disposing of so much waste has been a problem. Kingston, Tennessee had a containment pond spill about a billion gallons of liquid coal ash,
If coal power generators had to responsibly handle their wastes, coal would not be so much cheaper than solar and other renewable power sources.
What's more, the peels are a cheap waste material. Castro found they could be used up to 11 times before they stopped working as purifiers.
