1583: Biofuels

This paper is taken from a Society for General Microbiology briefing ‘Biofuels’

Year of Publication2012

Biofuels are renewable liquid or gaseous fuels made by and/or from living organisms or the wastes that they produce. The European Commission Renewable Energy Directive (2009) states that 10% of transport fuel should be from renewable sources such as biofuels by 2020. First generation biofuels are produced from edible crops. ‘Second-’ and ‘third-generation’ biofuels are generated from non-food crops including lignocellulose (5 kg of wood could theoretically produce up to 2.5 litres of ethanol) and algae (which potentially could produce up to 100 times more oil per acre than any terrestrial plant).
