The advantages and disadvantages of converting bio crop waste to electric energy 11720166 Shohei Iwamoto
Bio crop waste We people eat crop everyday. ・Rice ・Wheat ・Corn ・Sugaretc.. Crops →We eat or use only a part of them. The rest of them, “bio crop waste” can be used in various ways.
The various ways of usingbio crop waste From bio crop waste we can produce ・Methane gas ・Ethanol ・Hydrogen etc.. These can be used as sources of energy . →electric generation →agrichemical →medicine
The advantages of converting bio crop waste to electric energy ・Carbon neutral CO2 emitted by generating electric energy is equal to CO2 plant absorbed. There are no increment in CO2. photosynthesis ・No depletion growth CO2 absorption CO2 Electric energy ・Low cost bio crop waste electric generation
The advantages of converting bio crop waste to electric energy ・No depletion • Bio crop waste is not exhaustible resource. • →People grow a crop and the crop has parts we don’t eat. • Cf.)Oil will run out in about 42 years.
The advantages of converting bio crop waste to electric energy ・Low cost • Bio crop waste is “waste.” • There are many bio crop waste in the world. • →It is important to use the waste effectively.
The disadvantages of converting bio crop waste to electric energy ・Dependence on the season • In harvest season, there is a large amount of bio crop waste but in planting season is a small amount of it. • →Stable electric energy supply is difficult .
The disadvantages of converting bio crop waste to electric energy • ・Low energy density • Bio crop waste has small weight but has a large • volume. • →A large amount of bio crop are needed to generate electric energy.
Conclusion The advantages and disadvantages of converting bio crop waste to electric energy Advantages : Carbon neutral No depletion Low cost Disadvantages : Dependence on the season Low energy density
