Synopsis: Environmental challenges: Waste issues: Waste:

since tissues are shot through with blood vessels bringing in nutrients and ferrying away waste. What's emerging is a picture of these receptors as a kind of general-purpose chemical sensor.

The water burns the waste at temperatures of 1000 degrees Celsius, so high that there no smell.

The next generation of the machine could process waste from 100,000 people and produce about 22,700 gallons of drinkable water and 250 kilowatts of energy a day. f we get it right,

a process that can take days and wastes valuable time, often leaving those working in asbestos-laden buildings at risk of exposure.

And, only a small portion of solid waste is being recycled or composted. These trends are having effects across society and the economy

material waste is reduced considerably and the process has low to zero harmful emissions. Large-scale aerospace parts can

The crushing of rubber waste is more environmentally friendly and resource-efficient than producing new rubber products an important aspect in view of the rising costs of energy and raw materials.'

Plastic waste, which has a tendency to spread to even the remotest environments, can take centuries to decompose,

The upshot of this is that a lower proportion of plastic waste is recycled compared with other materials:

However, it should be pointed out that Europe also uses plastic waste as an energy source, and so, together, energy recovery and recycling use up more than half of the Union's plastic waste.

Going with the flow The variability in the quality of inputs also leads to major fluctuations in the viscosity,

resulting in significant waste. The EU-funded project'Sensor-base ultrasonic viscosity control for the extrusion of recycled plastics'(Ultravisc) has broken the mould

The two-year project sought to improve the recycling of post-consumer plastic waste by compensating for impurities

Ultravisc is expected to reduce waste by about 2%,down time by around 5, %and lower energy consumption by 5%when used on extruders.

When the granules are saturated they can be buried safely in the ground as inert waste. Behind the development is led by a consortium Loufakis Chemicals SA in association with three SMES involved in water engineering,

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.

(or biomethane as they might say across the pond) gas which requires the annual waste of five people to produce according to the operator of the Bristol sewage treatment works GENECO.

A single person annual waste both edible and flushable would fuel the bus for 37 miles.

The annual waste generated by an entire busload of passengers would provide enough fuel for a return trip across Great britain from Land's End in the extreme southwest of England to John O'Groats in the extreme northeast of Scotland.

The facility is capable of producing an estimated 17 million cubic meters of biomethane from this waste each year.

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.

this development can also reduce potentially harmful waste from LEDS generally made from toxic elements.

To synthesize waste into CDS, Sarswat and Free employed a solvothermal synthesis, or one in which the waste was placed into a solvent under pressure

and high temperature until CDS were formed. In this experiment the researchers used soft drinks and pieces of bread and tortilla.

and characterizing CDS derived from waste is a very challenging task. We essentially have to determine the size of dots which are only 20 nanometers or smaller in diameter

the use of food and beverage waste as the starting material for QDS allows for reduced waste

To be able to use this waste for creating LEDS which are used widely in a number of technologies would be an environmentally sustainable approach.
