For this reason methanol fuel cells will be used, where the combination of methanol and oxygen produces water and carbon dioxide as a waste product (note that the carbon footprint in this case is neutral in that the methanol will be produced by photosynthesis, removing CO2 from the atmosphere).

Not exact matches

Materials derived primarily from renewable sources such as replenishable agricultural feed stocks, animal sources, marine food processing industry wastes, or microbial sources, and can break down to produce environmentally friendly products such as carbon dioxide, water, and quality compost.

Crocodiles use a waste product of metabolism — the bicarbonate ions formed when carbon dioxide dissolves in water — as the trigger for haemoglobin to unload the oxygen it carries.

Adapted to their very hot but watery environment, these microbes metabolized hydrogen - rich compounds or dead or live organic materials to derive the energy that sustains anaerobic life, including sulfate - reducing bacteria that produce Hydrogen Sulfide (H2S), fermentative bacteria that produce carbon dioxide and alcohol -LRB-- OH), and methanogenic bacteria — the methanogens found in sewage and mudflats today — that produce methane (CH4) gas as a waste product.

Although Solar radiation and lightning (which has been detected by the ESA's Venus Express probe in 2007) should be producing large amounts of carbon monoxide (CO), the gas was found to be scarce, as if something was removing it (such as hydrogenogens, diverse bacteria and archaea that grow anaerobically utilizing CO as their sole carbon source and water as an electron acceptor to produce carbon dioxide and molecular hydrogen as waste products).

Your small blood vessels (capillaries) will widen to deliver more oxygen to your muscles and carry away waste products, such as carbon dioxide and lactic acid.
