Sustainable Biodiesel

Pronounced fos, the Greek word φως or phōs, literally translated in English to phos, means light. Fos Biofuels is an early stage, renewable energy startup in the business of recycling grease to energy in the form of biodiesel fuel.

Fuel of the Future

Biodiesel replaces conventional diesel fuel and shows a lot of promise. Biodiesel produced from waste grease shows even greater promise for the following reasons:

• Environmentally friendly
• A renewable source and is abundant in supply
• Can be produced immediately at a very low cost
• Usable in any conventional diesel engine pure or blended with regular diesel
• Delivers equivalent or greater engine performance and mileage
• Substantially decreases harmful emissions

A study conducted in the UK demonstrated that biodiesel fuel processed from cooking oil and tallow produces the least amount of CO2 emissions when compared to fossil fuels and crop based forms of biodiesel. Not all biodiesel is sustainable. Any crop based biodiesel (soy, palm, rapeseed) is a net energy negative. Cooking oil biodiesel is 3.2 positive. The graph below compares CO2 emissions of various types of biodiesel compared to fossil fuels (move your mouse over the image to enlarge the graph).

Why Fos Biofuels?

Not all biodiesel is sustainable, so in order to be truly sustainable, our feedstock, business practices and production methodology must all be sustainable.

• Waste vegetable grease is our only feedstock
• Water-free washing process
• Continuous flow refining process
• Community driven business model, our products are "locally produced, locally consumed"

In addition, Fos will be using a dual fuel boiler which will run on the main byproduct of the biodiesel production - glycerin. 90% of our heating needs will be covered in the boiler fueled by the waste glycerin. In our specific application, this means that 900,000 BTU per hour will be derived from the waste glycerin, rather than from natural gas.

These reasons allow Fos Biofuels to sustain reasonable levels of both capacity as well as production output. And, we are able to develop long term partnerships with communities and provide jobs along the way.
