Climate protection with algae technology

摘要

Using an innovation from a Cana-dian firm, industrial companies can reduce their CO_2 emissions. Pond Biofuels, based in Ontario, Canada, has developed a technology with which algae absorb carbon dioxide and can subsequently be used as an alternative energy source for biodiesel and pellet production. The innovation is currently being tested at cement company St. Marys Cement Group. Pond Biofuels positions algae in the cement company's chimney, which then absorbs the majority of the carbon dioxide via photosynthesis. The saturated algae can then be used to produce biodiesel or pellets. In the cement plant, 250,000 tons of algae could be produced. According to Pond Biofuels, this would be enough to manufacture 29 million litres of biodiesel.
