AB The growth of population and per capita income has led to the indiscriminateuse of resources, especially those of fossil origin, causing several ecological crises. Agricultural systems havedeveloped over time in order to comply with the population growth. However, this agricultural development isreaching a limit due to intense mechanization, widespread use of chemical fertilisers and pesticides, use of landand water. It is therefore important to find ways to make production more sustainable, while ensuring food securityand human and ecosystem health, alleviating environmental impacts.The environmental concern about the use of non-renewable sources drew attention to the use of renewablebiomass for the production of biofuels and bio-based products. Examples include first-generation (1G) feedstocks,such as starch crops (e.g., maize and wheat grains), which compete with food/feed markets. Agricultural andindustrial processing residues, namely second-generation (2G) feedstocks, are also of interest for use in industrialfermentation processes, although, to date, they have fewer technological advantages in relation to 1G biomass.Bioeconomy and circular economy are key concepts to promote the development of more sustainable productionprocesses, which promote compliance, by governments, with the commitments and initiatives of the 2030 Agenda,the United Nations SDGs and the Paris agreement, among others. In this context, significant efforts in thesustainable production of agriculture and bio-based products are essential for sustainable development. The mainobjective of this doctoral thesis is to assess the environmental and economic impacts of bioproducts, consideringfood and bio-based products, by means of the Life Cycle Assessment (LCA) methodology.
