South Portland pilots locally made biodiesel in vehicle fleet
In 2016, South Portland partnered with Maine Standard Biofuels (MSB) to use a B20 blend of biodiesel in select city vehicles. The pilot project was implemented to test the efficacy of the fuel in all conditions, including during the coldest months.
Examining the use of biodiesel was one of the actions identified in the City's Municipal Climate Action Plan (2014) to reduce greenhouse gas emissions and move away from petroleum-based fuel toward non-toxic alternatives. According to the US EPA and the California Air Resources Board, biodiesel is one of the cleanest and most efficient ways to achieve these goals, and can reduce carbon emissions in vehicles by as much as 80% depending on the feedstock and blend.
Maine Standard Biofuels recycles used cooking oil to make biodiesel at its Portland-based refinery. The company collects the used oil from restaurants all over New England, including more than 30 establishments in South Portland. In fact, South Portland generates enough used cooking oil to make nearly 60,000 gallons of B20 biodiesel fuel. That fuel will reduce CO2 emissions by over 200 tons. Furthermore, any waste from the biodiesel process is further processed into clean energy and eco-friendly cleaning products.
