Empresa cria conversor de biodiesel

(Notícia em Inglês)
Tucked away in a corner of an empty warehouse at McDonnell Horticulture is a $500 homemade contraption that could save the business and its customers thousands of dollars.

The device is a biodiesel converter. It is a gently used water heater and two 55-gallon barrels connected with nongalvinized pipes, valves and tubing. There are a bubbler, a compressor, a heater and a motor.

The converter is a high school science fair project that earns a D-minus for appearance but an A-plus for effectiveness.

It converts old cooking oil that commonly comes from deep-fat fryers at local restaurants to biodiesel fuel for the 16 tractors at the 225-acre nursery on old U.S. 1 in Cameron.

Biodiesel is made by chemically altering the oil -- essentially thinning it down -- to allow it to run in an unmodified diesel engine.
