...renewable primary products

topics
Topics
  • Definition of biofuels
  • Different types of biofuels
  • Types of plants used worldwide
  • Rapeseed oil in Germany
  • Comparison to other fuels
  • Advantages and disadvantages of biofuels
definition of biofuels
Definition of biofuels
  • Produced from renewable biomass material
  • Commonly used as an alternative
  • Cleaner fuel source
  • Much cleaner than petrol/diesel alternatives
different types of biofuels
Different types of biofuels
  • Bioethanol
  • Biodiesel
  • Biogas
  • Biobuthanol
bioethanol

Bioethanol

Actually ethyl alcohl(also referred to as ethanol)

Identical to drinking alcohol by its composition

Mainly two ways of producing alcohol

1. synthesis of hydrocarbons

2. from biomass

Advantages
  • climatic change needs reduction of the greenhouse effect
  • less toxic
  • conserves ernergy
  • saving of resources
  • biodegradable
  • economize fossil basic materials

-> e.g. Oil in place is unlasting

disadvantages
Disadvantages
  • losing of nature (e.g. cultivation of oilpalms)
  • acidification of fields
  • water pollution by pesticides
  • eutrophication of waterbodies
  • higher price of corn, palm oil etc.
  • reduction of richness in species
  • Eutrophication: (-> excessive plant growth and decay; reductions in water quality, fish, and other animal populations)
