文摘The present study aims to provide a preliminary overview of the sustainability concept when biomasses conceived for food goals become the raw materials upon which different sectors,such as plastic or energy industry,can develop innovative strategies,according to a so called "greener" competitiveness.In the results hereafter presented,the definition of sustainability perspectives,according to the use of a life cycle assessment(LCA) approach,will be described for maize use as raw material in different sectors.The current biopolymer industry and conventional biofuel technologies,the so called first-generation biofuels,are the more and more in competition with the food sector.The presented environmental evaluation,in terms of air emissions,energy and water consumption,is useful in order to understand the sustainability of a bio-sourced product,in comparison with the equivalent item produced by fossil fuels.
