Corn Stove• How Much Corn Do You Use? – In a insulated house on a cold day about 1 bushel/day – On a cold night in the greenhouse about 5-6 bushels • A 30 x 96 greenhouse uses about 200 gallons of propane per night when it is 15 degrees F
BioFuels Project• Examine Economics – Nutrient Removal• Soil Properties – If remove large amount of biomass what is that going to do to soil properties
Diverse Stand• At MU Bradford Research and Extension Center – Low Input/High Diverse compared to a High Input/Monoculture • 18 different forbs and legumes • Switchgrass and Big Bluestem • Cutting Height • Seasonal Harvests Depending on Need
Future Goals• Wind Turbine – We use 12,000 kwatt/month – 10 kwatt wind turbine • Cost $32,000-58,000 – Produce 2,416 kwatt/month – Supply 23% of our electricity – 16 year to pay off with another 14 years of free electricity
Z er o Car bon F ootpr i nt Vegetable & Compost P r oducti on System University of Missouri Bradford Research & Education Center & MU Campus Dining Tim Reinbott, BREC Superintendent; Eric Cartwright, MU Campus Dining; Steven Kirk, MU Division of Plant Sciences An estimated 40% of all food produced in the country is discarded, according to a new federal report. Each day, every person in the U.S. puts about 1,400 calories worth of food in the garbage, according to researchers at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Food waste has increased 50% since previous estimates were made in 1974, and now totals some 150 trillion calories per year. SOURCE: CALIFORNIA EMERGENCY FOODLINKThe University of Missouri AnimalSciences and Veterinary Medicineproduce 1500 tons of manure andbedding material each year. MU’sCampus Dining produces 270 tonsof food waste annually. MU’s Campus Dining halls generate 3,000+ gallons of Waste Vegetable Oil annually. This WVO will be converted into biodiesel. Biodiesel will power the trucks, tractors & equipment used forSeveral large-scale composting vegetable production as well as pick-up and delivery of foodmethods exist.

Let’s Make It Green!• Campus Dining Goes Through 3,000 gallons of Waste Vegetable Oil Each Year!
Make It Into Biodiesel! • 50 gallons every 48 hours • By product Glycerol which contains methanol • Challenge to remove the methanol, then the Glycerine can be – Composted – Burned – Animal feed – Made into soap
