Biodiesel

Biodiesel’s Environmental Benefits

Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics. It possesses high lubricating properties beneficial to reducing diesel engine wear, especially better than ultra low sulfur diesel (“ULSD”) which is produced by extensive hydro treating at the refinery causing poorer lubricity. Biodiesel also has emissions tendencies that are better than traditional petroleum diesel fuel since its use reduces the occurrence of unburned hydrocarbons. Biodiesel’s environmental benefits as compared to petroleum diesel include:

 

  • 78% reduction of global warming causing CO2 emissions;

  • 75% reduction of carcinogenic polycyclic aromatic hydrocarbons emissions

Biodiesel Production

Agrileum owns a 40 million gallon per year biodiesel facility in Memphis, Tennessee. This is a multi-feedstock plant that produces biodiesel from vegetable oil, animal fats and processed used cooking oil. The 17-acre project site also has a 10 million gallon per year feedstock pre-treatment facility along with a testing laboratory and storage tanks.

 

The technology of converting vegetable oils and animal fats into biodiesel is well established. The most commonly used, and most economical process, is called the base for free esterification of the fat with methanol, typically referred to as “the methyl ester transesterification”. The process reacts the fat/oil with alcohol (methanol) and catalyst (sodium or potassium hydroxide.)

 

This process involves four main materials - methyl ester (biodiesel), glycerin, feed quality fat and methanol, which are recycled back through the system. asdfasdf

Renewable Fuel

Biodiesel is a renewable fuel that is a drop-in replacement for petroleum-based distillate fuel. The largest segment of the distillate fuel market is diesel fuel for on-road and off-road use, which also includes fuel oils for heating and power generation. In 2009, the US market for distillate fuel was 52.7 billion gallons, according to the EIA.

US biodiesel production reduces the US’ dependence on foreign-sourced fossil fuels, creates US jobs and reduces greenhouse gas emissions. Biodiesel is simple to use, biodegradable, nontoxic and essentially free of sulfur and aromatics. It is an excellent lubricant that reduces diesel engine wear.
