From Poop to Fuel

  1. 1. BioFuel<br />From Food Scrapes to Sustainable Fuel Source<br />
  2. 2. What’s biomass and How Can You Get Energy Out of it?<br />Is it hard to get energy out of biomass? No, people have been doing it for thousands of years. <br />Biomass is made of organic remains from plants and animals which are taken mostly from harvesting and processing of agricultural and forestry crops.<br />Biomass are wastes and by-products that could be used as fuels for producing energy, instead of becoming landfill waste. <br />

  4. 4. What is Biogas and What Kinds of Biomass Are Good at Making Biogas<br />Biogas- Organic matter, especially plant matter, that can be converted to fuel and is therefore regarded as a potential energy source.<br />Biomass is all plant material, or vegetation, either raw or processed, wild or cultivated. Like trees, grass, corn and vegetables. <br />Even though the smell of manure from cows can be strong and disgusting, the waste is a rich source of energy that can be used to make electricity.<br />
  5. 5. Materials <br />9 empty 2-litre bottles of soda <br />40.75 grams of cow manure (as fresh as possible) <br />15.25 grams of mashed bananas <br />25.2 liters of distilled water or sometimes more, depending on the exact volume of the bottle <br />18 large-mouthed (about 3.5cm in diameter) latex balloons<br />Metric tape ruler <br />Scale, capable of distinguishing between 1g quantities<br />Duct tape<br />
  6. 6. Procedure<br />Clean the nine 2L bottles <br />Fill nine bottles with 5 grams of cow manure<br />Fill 3 of the bottles with another 5 grams of cow manure <br />Fill 3 of the bottles with 5 grams of raw vegetables<br />Fill the last 3 bottles with 5 grams of mashed bananas <br />
  7. 7. Procedures continued<br />Each bottle contains 10g of biomass<br />Fill up all the bottles to the top with distilled water<br />Place the latex balloon over the soda bottle, un-inflated<br />Secure the balloon with some Duct tape <br />Measure the diameter of the balloon twice a day for a period of two weeks<br />
  8. 8. Results<br />
  9. 9. Conclusion and Things to try next time<br />Experiments involving bacteria can be very difficult to grow.<br />I think this experiment would produce better results if it was done on a bigger scale. More Cow Poo!<br />I think that pH had something to do with how much biogas my experiment made. It was either too low or too high. If the pH was around 7 that probably would have been better.<br />
  10. 10. Conclusion and things to try next time<br />I think temperature had an effect on my experiment. Bacteria only grow at specific temperatures. For example when we brought the experiment inside they seemed to start producing biogas.<br />Next Time<br /> Monitor pH in each bottle<br />Monitor the temperature in each set of bottles<br />Make bigger biodigesters, and use more manure.<br />
  11. 11. Chopping vegetables<br />for Test #2<br />
  12. 12. Weighing manure<br />Starting Test #1<br />
  13. 13. Adding distilled water<br />Manure has to be fresh.<br />Thanks Little Farm<br />
  14. 14. Thank you<br />
