The green building studies and reports we spotlight cover the following topics: The potential financial benefits of green retrofits; the importance of overcoming the social and psychological barriers to green building; the use of impact fees to encourage green building; the use of mandates and incentives to promote sustainable construction; feedback from the construction industry on the risks that come with green building; global green building trends; green practices reported by facilities management professionals; and reshaping municipal and county laws to foster green building.
Algenol Biofuels, a Florida biofuels startup and DOW Chemical Company announced a pilot-scale algae-based integrated biorefinery that will convert CO2 into ethanol. The patented technology developed by Algenol Biofuels uses CO2, salt water, sunlight and non-arable land to produce ethanol, which can be used as a fuel or as a feedstock, replacing natural gas in the production of plastic. The algae is grown in long plastic covered troughs, called bioreactors that are filled with salt water that has been saturated with carbon dioxide gas, which provides the carbon the algae needs for photosynthesis.
In this first post of the BIOFUEL UPDATE — a newly introduced feature of The Green Economy Post — I write about how so called first generation Biofuels such as Corn Ethanol that are derived from food crops or grown on land that otherwise would be used for food crops may be worse for global warming than burning gasoline is! This reconfirms in my mind the pressing need for the biofuel sector to move towards non-food biofuel crops that also are grown on marginal land; crops such as algae, switchgrass, jatropha etc. In other news the Danforth Science Center in Saint Ls. MO gets $15 million in federal funds. Fedex announces plans to get 30% of its fuel from second generation non-food crop biofuels by 2030. OriginOil has developed a simpler and more efficient way to extract oil from algae.
