Apparently 20% of the waste in our modern landills is non-degradable plastic. The Ozmotech solution is to convert this into diesel fuel. Their patented process uses liquefaction, pyrolysis and catalytic breakdown to render 1kg of waste plastic into 950ml of oil or Green Fuel. This contains the same energy content as conventional diesels, but with "significantly reduced emissions levels". Existing diesel engines are said to run fully effectively on these fuels with no engine modification. It works best with PP, PE and PS plastics.Meanwhile, Australian scientists have discovered that removing nitrogen and oxygen bubbles from water - by means of a hydrophobic, gas-permeable membrane - greatly increases plain water's ability to break up oil and dirt:
This could reduce our use of detergents, which create environmental problems when they are washed into the water system: detergents can fertilize algal growth so much that animals in swamps and lakes are harmed.And just to round things out, a solar car designed by the Aurora Vehicle Association of Melbourne has just broken another record, by traveling 1255 kilometers in 24 hours (which does indeed mean that it was running at night!). Again, thanks to Treehugger for that link.
Pashley and his team tested normal distilled water and degassed water by filling oily test tubes with water and shaking them for several seconds.
The tubes of degassed water became much more turbid, the team reports...this shows that the oil was dispersed throughout the water as tiny droplets, and suggests that degassed water could lift oily stains off clothing.
These stories offer a microcosmic view of the design revolution that's happening in countries all over the world. (And not just first-world countries, either; the trend towards leapfrogging can allow poorer countries to make environmentally sound technological gains, often by virtue of the fact that they're not hampered by reliance on an outdated, transitional industrial infrastructure.)
