Potential of Greenhouse Gas Reduction Producing and Using Biodiesel from Fatty Waste



Resolution of climate change, economy and energy decentralization problems is related to development of biofuel use and production. An increase in biofuel use and production is to ensure the reduction in greenhouse gas emissions. Following a life cycle method comparative analysis of rape methyl ester and diesel before their use in diesel engines has indicated that in production of rape methyl ester the growing of rape seeds consumes 56% of energy whose expenditure is directly dependent on rape productivity. In order to decrease energy expenditures the use of fatty waste is expedient. It is determined that production of biodiesel from frying fats yields 1.37 MJ and 98.15 g CO2eq. economy for one MJ of product compared to diesel. Potential of used fats methyl ester greenhouse gas reduction in the life cycle reaches 0.87 and is 27% greater that that of rape methyl ester. Used fats methyl ester meets balance criteria therefore in our country the waste collection system from food industry and catering enterprises is to be established.
