Second-generation biodiesel feedstocks

Wong, A. (2007) TaU oil as feedstock for second-generation biodiesel production in southeastern USA. Forest Chem. Rev., 117 (6), November-December, 5-10. 

The Directive 2009/28/EC also promotes biodiversity protection of threatened species in those lands where biodiesel and bioliquid production would have negative impacts on flora and fauna. Raw materials used in biodiesel and bioliquid production should therefore achieve the status of sustainable, by competent bodies, before being processed. In the longer term, the 2007 Renewable Energy Road Map (European Commission, 2007) specifies the adoption of a minimum 10% consumption of biofuels in the transport sector. Biofuels use in the transport sector would contribute to 14% of total market fuels (corresponding to about 43 million tons of Equivalent Oil) and the share may increase from either current bio—ethanol production in Sweden or biodiesel production in Germany and other European Union countries or other feedstock such as ethanol from straw, rapeseed oil, palm oil, and second-generation biofuels mainly obtained from wood processes (De Lucia, 2010). 

The production of biofuel from edible oils (first generation of biodiesel) has increased many environmental issues such as competition over land usage for crops agricultural and biofuel production. In conjunction with this, food shortage, raised food prices, and destruction of biodiversity as deforestation occurred (Lin et al., 2011) are major causes for concern. The production of biodiesel from second-generation feedstocks should be encouraged to make these more viable/profitable and will be discussed in depth in Section 6.2.3.1. 

Second-generation biofuels are so named due to they being developed after the first-generation biofuels (such as biodiesel), which are those derived from conventional feedstocks.First-generation biofuels are not ideal they compete with the food cycle and require a significant amount...
