1. Animal Waste Digesters

2. Bio-diesel Bio diesel can be made with many different plant residues, weedy species, algae Depending on the source, bio-diesel has the potential to be carbon negative On-site production increases self reliance Roger Rainville Bio-Diesel production

3. Ethanol production Most large-scale ethanol is produced from corn. – 40% of corn grown in US is for ethanol – Corn is a picky crop that requires significant fossil fuel inputs – By some estimates ethanol from corn is carbon neutral – Controversial Some farmers produce their own ethanol for their farm and/or community use – Dan West turns excess fruit crops into ethanol http://www.sare.org/Learning-Center/Bulletins/Clean-Energy-Farming/Text- Version/Profile-Dan-West

4. But what about organic farming? Limited synthetic inputs – pesticides organic pesticides, such as Bt toxin, are still used. – chemical fertilizers Not all standards are the same Organic ≠ Sustainable – Example: Earthbound Farms Industrial approach but still aligned to USDA Organic Standards

5. Don’t forget about the soil! Soil is a main focus of sustainable agriculture
