Ten tons of resources are used-produce every ton of new products, (1) and levels of CO 2 emissions from burning coal, oil and gas in the process are also high.Manufacturers are different ways of reducing looking (2)-CO 2 emissions and reducing costs at the same time. There (3) several fuels which can be burned in industrial processes instead of the carbon-based ones. The use of biofuels-bioethanol and biodiesel-reduces the CO 2 emissions (4) a typical factory significantly. Countries like Brazil already have a strong biofuel industry, and now in Europe more crops for biodiesel (sugar cane,cereals, sunflowers etc) (5) being grown. Another source of alternative fuels is the waste from (6) industrial processes.

This type of fuel has the advantage of being (7) 一 than other fuels for the company that buys it. If we add to this list other waste like vehicle tyres, it is clear that CO 2 emissions can be reduced (8) the future. 1 A to B for C so that 2 A in B for C to 3 A is B are C's 4 A to B by C of 5 A are B is C will 6 A another B others C other 7A cheap B cheapest C cheaper 8 A in B at C on
