Lignocellulosic biomass represents an attractive, large-scale source of renewable carbon from which renewable fuels and chemicals can be produced. In this context, the production of alkanes and olefins would be especially attractive by providing exact replacements for fossil-based fuels and chemicals. From the estimated domestic potential of 1.2 million tonnes dry mass of agroforestry residues such as mixed grasses, crop residues or broad-leaved trees, roughly 14% of the annual jet fuel consumption in Switzerland could be covered. Thus, a maximum of 675’000 tonnes of CO2 emissions from fossil fuel can be avoided.This joint project aims at developing the technology for the production of renewable alkanes and olefins from lignocellulosic biomass through subsequent biochemical and catalytic conversion processes. The three individual projects cover the two main conversions as well as the sustainability assessment. In detail: (I) Production of carboxylic acids from lignocellulosic biomass by adapting a consolidated bioprocess employing a microbial consortium, II) building a systematic conversion platform for these carboxylic acids to be converted to alkanes and alpha-olefins, III) doing a holistic feasibility and sustainability assessment including a broad scenario of feedstocks and target products along the whole value chain.The sustainability study could contribute to the decisions-making process of stakeholders in the industrial, investment and policy communities. Certain advanced research concepts that will be developed could have considerable interest for academia. Furthermore, the targeted products and processes are most interesting for petrochemical market or chemical industry to be further developed in the context of a CTI project (Commission for Technology and Innovation).
