The group comes from the unification of two groups with more than 15 years of scientific experience, whose common objectives were related to the industrial use of renewable resources (lignocellulosic and waste biomass) together with the minimization of the possible environmental impacts that these activities may produce. These objectives involve the search for an optimal process for each resource and the study of very diverse technologies which should include the manufacture of cellulosic and paper with different biomass lignocellulosic waste, fractionation of the biomass through hydrothermal processes to obtain sugars and other organic components, different systems of obtaining energy (thermochemical processes), production of compost with the least valuable fractions (also with municipal solid waste and sludge of sewage treatment plants), studies of the degradation of the organic components of the different biomass and derivatisation of organic compounds extracted from biomass for industrial use in systems involving a minimum generation of effluents (liquid or gaseous).
