Sustainable Practices used to earn Travel Green Wisconsin Certification
Committed to reducing our footprint, we have enacted numerous green practices. We explain one of our more sustainable practices of using WVO(Waste Vegetable Oil) for our E350 and E450 kayak passenger transportation buses.
Owner David Rack studied alternative energy at Evergreen State College along with Kolby Bray-Hoagland and Sam Stout, they were able to Design, obtain funding, create, and place a biodiesel processor on the organic farm of the Evergreen campus. David, inspired from his studies of biodiesel, but put off by the inorganic compounds (Methanol/ Lye) used to create biodiesel, switched the focus of his own sustainable business practices to using straight waste vegetable oil to power his kayak passenger transportation buses.
Why use Waste Vegetable Oil instead of Biodiesel?
- Making Biodiesel is a difficult process involving chemicals(methanol and Lye). Cleaning Waste Vegetable Oil is a safer process that does not involve chemicals, but instead uses a centrifuge to clean the oil.
- 1 Gallon of WVO is 1 gallon of fuel. 1 Gallon of WVO creates 3/4 of a gallon of biodiesel. Thus more fuel using WVO.
- WVO uses an onvehicle conversion system that is a one time cost with minimal wvo cleaning costs, vs. Biodiesel, there is continual cost involved with chemical costs, as well as processing costs.
David continues his research of using biofuels, he is especially excited about the up and coming use of algae to create biodiesel. David is happy to answer questions regarding the use of biodiesel or vegetable oil as a fuel. Email him at dwrack@yahoo.com
