Long-term sustainability of bio-components production

Biofuels play an increasingly important role in motor fuel market. The list of biofuels (bio-components) in accordance with EU legislations contains a number of substances not widely used in the market. Traditionally these include: fatty acid methyl esters (FAME, in the Czech Republic methyl ether of rape seed oil) and bioethanol (also ethyl terc. buthyl ether ETBE, based on bioethanol). The availability and possible utilizations of bio-component fuels in Czech Republic and Serbia are discussed. Additional attention is paid on the identification of the possibilities to improve effectiveness of rape seeds cultivation and utilization of by-products from FAME production (utilization of sew, rape-meal and glycerol) which will allow fulfilment of the sustainability criteria for the first generation biofuels. The new approaches on renewable co-processing are commented. The concept of 3E (emissions, energy demand, and economics) is introduced specifying three main attributes for effective production of FAME production in accordance with legal compliances. Bio-components price change is analyzed in comparison to the price of motor fuels, identifying possible (speculative) crude price break-even point at the level of 149-176 USD/bbl at which point bio-fuels would become economically cost effective for the use by refiners
