Abstract

Among the 17 sustainable development goals (SDG) adopted by the UN 70th general assembly in December 2015, SDG7 “Ensure access to affordable, reliable, sustainable, and modern energy for all”, SDG12 “Ensure sustainable consumption and production patterns” and SDG13 “Urgent action to combat climate change” are interrelated and have become a high priority on the research agenda of geochemists and chemists. The reserves of fossil fuels are being increasingly depleted and the current energy scheme is causing enormously high levels of CO2 emissions at the planetary level that is among the major reasons for climate change through increasing greenhouse effect. In addition, oil and natural gas constitute currently the major feedstocks for the chemical industry and it is necessary to develop new processes based on renewable resources as alternative to the chemicals and processes that are being used at present. Biomass can become a source for a certain percentage of transportation fuels and, in addition, can provide novel materials and chemicals that could substitute advantageously industrial processes based on non-renewable resources. The symposium will address various aspects of biomass utilization including application for transportation fuels, but also for new chemicals and materials that can be obtained from cellulose, hemicelluloses, carbohydrates, and lignin. Transformation fuels derived from biomass can serve to reduce CO2 emissions caused by the use of fossil fuels and thus contribute to reduce the risk of climate changes. Oil and natural gas are also currently the major feedstocks for the production of solvents, polymers and other bulk chemicals. For the sake of sustainability, there is an interest to develop novel processes based on the use of renewable raw materials. The chemicals thus obtained are expected to play an important role as monomers for the production of new polymers, as solvents, as new molecules for consumer goods production and as starting materials for fine chemicals. The added value of such chemicals should be larger than biofuels and this should be a driving force for the development of new eco-respectful processes. The eco-design of new performance ingredients for industry will also be integrated. This Symposium will cover enzymatic and fermentation processes, as well as, purely chemical reactions to convert renewable resources into useful starting materials. Different platforms such as those derived from furfurals, valerolactone or levulinic acid, are expected to be represented in the Symposium.
