3R (recycle, reduce, reuse) : example

The price of petrol is "fixed" by our government.
However, the "fix" is based on their strategy and planning but not to also observe on the price/basket(桶) as published by OPEC (always updated).

With the "hiking" price of the petrol (or petroleum) from 2002, there are a number of research in renewable energy particularly bio-fuel.
However, bio-fuel is blamed for the food price crisis starting early of this year (SinChew, TheStar).
On the other hand, CO2 is still "released" (or produced) throughout the combustion of the engines although less CO2 is reported in using bio-fuel.

While all these issues (petrol, food) are needed to be resolved, the global warming could be the biggest challenge to overcome as we have heard news of disasters happening worldwide (China, Japan, USA, Europe..etc).

I think 3R concept can be the main theme in research to help while waiting for the "big boys" like G8 to agree to reducing their CO2/countrycount by 2050 [SinChew,TheStar] (can the earth wait? can the others wait?).

In helping the mitigation of global warming, this news reported a research in re-using the waste.
The re-use would help to reduce the waste.
Hope there are more and more research utilizing industrial waste to achieve 3R.
