The use of biomass for energy purposes, especially first generation, is often debated. According to Carlos Henrique de Brito Cruz (Fapesp, Brazil), this discussion is often clouded by preconceptions. 'In Brazil, it is not an ifif-discussion but an andand.'

De Brito Cruz stated that sustainability is very important to ensure that flora, fauna and human rights (landownership etc.) are not violated in the process. ‘We need to protect the forest, wildlife and indiginous populations. Also we need hightech to maximise outputs and to minimize inputs. Especially water usage is and will be a critical factor. Therefore, for example crop varieties need to be cultivated which do not need the amount of water and/or pesticides. Ecology and economy should go hand in hand and not against each other.’

At the moment, the usage of biomass for energy purposes (electricity, fuels) world wide is relatively low, hovering around the 10 per cent mark. In 2035 this share will be bigger, according to IEA, around the 15 per cent mark. ‘Interestingly, the share within renewable energy of advanced energy/fuels (f.e. 2nd generation) will be 70 per cent. Ideally, the share of biomass for energy purposes should be 25 per cent in 2050 if the targets set in Paris at the COP21 are to be met.’
