On-Farm Oil Seed / Biodiesel Project State Line Farm, Shaftsbury, VT

A lot of farms and farmers in the Northeast are looking for new, ‘non-commodity’ enterprises. A lot of farms are also looking for sources of renewable energy

Our goal Farms working together to make their own fuel, using their own raw materials, with sustainable practices.

Making biodiesel from waste vegetable oil in the old dairy barn

The first crop of oil seed crops, but no way to extract the oil for fuel.

In 2005 an oil seed press was purchased.

Other farmers helped buy the press, and grew test plots of sunflower, canola, other oil seed crops.

The crop looks good now, but deer and bird damage, or diseases can be a problem.

2007 sunflower variety trial at State Line Farm; yields ranged from 1,247 to 2,396 lb/acre

Get the 1960’s combine ready

In northern VT canola trials with 24 varieties had an average yield of 1,800 lb/acre

First set up for pressing the seed for oil and meal

a temporary settling tank

Seed meal = livestock feed, worth about $200+ per ton, roughly twice that if organic

Sweet sorghum (for ethanol) August 1

Extracting sweet sorghum juice

This still makes ethanol from fermented ‘sugar crop’ juices

Scaling the project up in 2006…with funding from VT Sustainable Jobs Fund

John and Steve designed and built the building

Vermont’s first on-farm oil seed processing facility

Putting the system together – many used parts!

“Farm fresh” biodiesel – but not ASTM tested (that’s another story)

Future work Oil and alcohol crop production trials Economic analysis Comparing processing equipment Market development, co-operative formation? Regulatory issues
