Self Contained Mobile Biodiesel Processing Trailer
The farm based self contained mobile biodiesel plant constructed by GreenStart is based on a common aluminum beverage trailer platform. The heat and power is provided by a 3 phase diesel generator coupled with a 10hp air compressor. Each functional component is designed to fit the standard beverage skid of 36″ square which enables swapping of components. The shutter sides provide secure weatherproof environment for storage and transport. The low deck height also facilitates operation and maintenance from the ground level.

An allen-head set screw and matching nut
A waterproof switch and housing
A drill bit and drill, some paint, etc
A racket ball or similar

An oxy-acetyl torch or mean drill press
About one full, well-prepared day
