How it works Yellow grease, waste oil (soy, vegetable, corn, olive etc.) surplus oil, out-of-date or specification cooking oils are recovered from processing plants and area restaurants/food processing centers as feedstock.
The feedstock is then subjected to a transesterification or alcoholysis process that uses alcohol (methanol) and sodium hydroxide to remove glycerol from the oil and generate clean feedstock.
The mixtures are heated to separate fatty acids from the oil. The resulting B100 biodiesel feedstock is blended with diesel fuel to use in an internal combustion engine. The fuel blend powers a diesel generator.
At the BioPur site, a stationary electrical generator that creates electricity to operate local or on-site electrical equipment (grid-independent) or, generate electricity to add to an electrical power grid or utility (grid-connected).
Creating fuel from feedstock to run a generator has the following benefits: Feedstock such as waste cooking oils are not put in a local water supply or landfill, reducing water and land pollution Feedstock as an energy source reduces the country’s dependence on foreign energy sources such as oil and coal Feedstock as an energy source reduces the inherent pollution created by exploration, drilling or mining, and transporting petroleum or coal-based energy sources
