“…Pyrolysis oil has a calorific value which is more or less half that of fossil fuels and can be used in diesel engines for static applications, whereas the gas is often used for internal energy provision. Furthermore, a life cycle analysis (LCA) showed that pyrolysis oil from wood waste is environmentally friendly (Zhong et al, 2010). Ning et al (2013) also used LCA and confirmed that pyrolysis oil has a lower environmental impact compared to fossil fuels.…”

a b s t r a c tThe main barrier in the commercialization of phytoextraction as a sustainable alternative for remediating metal contaminated soils is its long time period, which can be countered by biomass valorization. From an environmental point of view, fast pyrolysis of the biomass is promising because its lower process temperature prevents metal volatilization. The remaining question is whether fast pyrolysis is also preferred from an economic point of view.Therefore, a techno-economic assessment of fast pyrolysis has been performed for a case study in the Campine region in Belgium. For this region, willow trees cultivated in short rotation have the right characteristics to serve as a phytoextracting crop. A techno-economic assessment requires by definition a multidisciplinary approach. The problem statement urges for a focus on the economic profitability from the viewpoint of an investor, including economic risk analysis.Fast pyrolysis seems more profitable than gasification. The profit is dependent on the scale of operation, the policy support (subsidies) and the oil yield. The economic risk can be reduced by increasing the scale of operation by means of complementing feedstocks, and by valorization of the char byproduct by subsequent processing to activated carbon.

Life cycle assessment of bio‐oil from woody biomass through two pathways was carried out using a one‐step pathway that utilizes fast pyrolysis of pine and a two‐step pathway that incorporates a torrefaction step prior to fast pyrolysis. A two‐step pathway with torrefaction at a temperature of 330 °C and pyrolysis at 530 °C had a global warming potential of about 6 g CO2 equivalent per MJ of bio‐oil compared to about 39 g CO2 equivalent per MJ of bio‐oil for a one‐step pathway using an energy allocation‐based analysis. For a one‐step pathway, the size reduction step made the highest contribution of over 50% of the overall global warming potential. Greenhouse gas (GHG) savings of up to 80% compared to heavy fuel oil (HFO) were achieved for a two‐step pathway in comparison to a one‐step pathway due to savings in size reduction energy. The use of renewable energy sources produced internally to provide process heat either by first burning char and then condensables from torrefaction (oil) or vice versa resulted in similar global warming potential reduction in comparison to use of natural gas to provide process heat. The bio‐oil production pathways were found to be more sustainable in comparison to HFO due to relying chiefly on renewable biomass rather than fossil energy. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd
