Resumo:

Biodiesel production is growing exponentially offering the energy network an alternative fuel from renewable sources. However, large quantities of crude glycerol are generated as a bi-product (10-30%) wt during the transesterification process of biodiesel. Although glycerol in its purified form has a number of uses, crude glycerol obtained from the biodiesel industry contains many impurities and requires expensive purification processes resulting in vast amounts of glycerol without adequate destination which are causing rise to many environmental concerns. Large scale applications of glycerol are necessary to accompany its production. This paper reports on polyesters obtained via the polycondensation of glycerol with aromatic acids and discusses life cycle analysis considerations of polyesters with respect to the utilization of glycerol, as a substitute to petroleum based materials in the synthesis of these polymers. These aromatic polyesters could offer a low cost environmentally compatible material for the production of components such as tiles, boards, sanitary vases and sinks for the construction industry.
