Os brasileiros produzem etanol a partir da cana de açúcar. Aqui na América do Norte, é com milho que o etanol é produzido.
Quer dizer, era; porque em Edmonton está sendo construída uma usina de etanol ao lado de um lixão. O lixo das casas da capital de Alberta vai virar combustível a partir de 2011.
Esta é a primeira usina no mundo que vai produzir etanol com os restos da sociedade de consumo. E isso em Alberta, uma província conhecida mundialmente por sua produção de petróleo. Com este projeto, Edmonton vai aumentar para quase 90% a reciclagem de seu lixo.
Turning Garbage into Fuel
Using waste to produce cleaner burning fuels is a major leap forward in Alberta's commitment to alternatives to landfills and an integrated energy vision.
Research confirms that Edmonton's residential solid waste that is not recycled or composted (and is now landfilled) is well suited to gasification into a synthetic gas that can be converted to methanol and subsequently ethanol.
In November, 2006, Edmonton committed to the development of a demonstration project at the Edmonton Waste Management Centre with financial support from the Alberta Energy Research Institute. A demonstration facility and associated research facility are expected to be operational by the end of 2010.
The demonstration facility will enable the City to divert more than 90% of residential waste from landfill, thereby reducing dependency on landfilling and reducing GHG production associated with landfilling. The research facility will be used to optimize the performance of the demonstration facility, evaluate the performance of gasification technologies using different waste materials, and facilitate research into the synthesis of syngas to ethanol and other biofuels.
Initially, the demonstration facility will produce methanol, followed by ethanol as research is completed. The goal of producing methanol and subsequently ethanol has both environmental and economic benefits since it supports the increasing demand for biofuels. Using waste as a resource for fuel will contribute to GHG reduction, reduce the need for food as feedstock for ethanol, and enable Alberta to lead the way in biofuel production.
This initiative means that in the future, Edmonton's garbage trucks may be refueling at the Edmonton Waste Management Centre with fuel made from the waste they delivered to the site.
