It is well known that CCS and CCUS are necessary, together with fossil fuels replacement, to reduce carbon concentrations in atmosphere (IEA 2011 , European Biofuels ). Moreover, biofuels can play an important role to replace fossil fuels, mainly when BECCSUS is added to the process, contributing to reduce carbon emissions and, in the case of ethanol production, carbon capture from production process is a very interesting option in terms of technical feasibility and cost efficiency.
Some existing experiences already exists such as the CCS at the corn-ethanol plant in Illinois, USA, supported by the US Department of Energy. In Brazil, the most common use for CO2 for soft drink industries, which buy carbon dioxide from some mills in the state of SP (for example, the Vale Onda Verde mill , at Nova Granada municipality). However, there are other possible uses, even with a higher added value. In Parana State, in Maringa, Raudi Industries purchase CO2 from Copcana mill to produce sodium carbonate and to be fed in wood greenhouses as well.
The main and most profitable sources for CO2 production associated to biofuel production include fermentation process, upgrade process of biogas from vinasse and exhaust gases from the boilers. In the case of biogas upgrade, it is important to develop advanced technologies for vinasse biodigestion and for biogas upgrade. This is particularly important in the case of sugarcane vinasse (a by-product of sugarcane ethanol).
In this context, the main objective of the workshop is to present and discuss the perspectives for BECCSUS and the existing experiences and challenges. The workshop will pay particular attention to the issue of science-based policy making, discussing the best ways to use the most up-to-date scientific results in the policy making cycle to assess the sustainability and mitigation potential of BECCSUS projects and applications.
High-qualified speakers are invited, from Brazil, US and Europe, to present existing experiences and to discuss the challenges. A recent Scientific Opinion on the climate benefits of the novel carbon capture and utilisation technologies, produced by the Group of Chief Scientific Advisors of the Scientific Advice Mechanism of the EU, as well as the Evidence Review Report produced by the SAPEA consortium of European Academies that provide the evidence basis for the Opinion will be presented and discussed.
