ethanol

The government has defended its decision to not pass the recommendations, saying that at the time of the report's relase, ethanol was cheaper than petrol.

After weeks of talks, the government said on Friday it would not be providing financial support for the bioethanol sector, which is facing increased competition from imported US ethanol.

It is similar to ethanol, which is used for alcoholic drinks, but is more toxic to humans because of the way it is processed by the body.

Smelling salts - a pungent mix of ammonia, water and ethanol - are marketed as improving mental alertness or boosting energy.

At a fuel plant near Hull, 20 tonnes of wheat are being poured from a lorry into storage, ready to be turned into ethanol – a type of alcohol that, when blended with petrol, reduces emissions.
