Today’s Discussion History of Bulldog Biodiesel Where we are now How biodiesel is made Advantages

History Student group founded Fall 2007 Purchased automatic processor in January 2008 Received Truman State University charter in April 2008

Current Monthly Statistics 15 students actively producing biodiesel Oil collection: 200+ gallons Production capacity: 400 gallons

How Biodiesel is Made Glyceride Fatty acid tail Glycerol Biodiesel Methanol KOH

Biodiesel Processors Processors range from… very simple & very cheap to…not so simple & not so cheap.

Wash TankReaction Tank Biodiesel Processors Methanol + KOH/NaOH Filtered Oil GlycerinBiodiesel Water Water out BIODIESEL

Advantages of Biodiesel Lower emissions –Acid rain-forming gasses –Carbon monoxide Diverts waste from a landfill

Advantages of Biodiesel Economic benefit –$5.5 million exported every hour for crude oil –20% comes from Saudi Arabia and Venezuela Domestic oil Foreign oil

How much does biodiesel save for you? Processor cost: $8000; pays for itself after ~3200 gallons (64 batches) Processors can be homemade much cheaper We are currently making biodiesel at a cost of $1.50/gallon Biodiesel cost per gallon fluctuates slightly based on cost of methanol, hydroxide

Waste Vegetable Oil (WVO) vs. Grown for Fuel Oil ** Yield given in lbs of oil/acre From:

Why use WVO? It’s waste that otherwise isn’t used WVO is often given away to biodiesel producers  NO COST Eco-friendly and cost effective Eliminates concerns about global food supplies due to food/fuel crop competition
