Resumo

BRAZIL FOR BIODEGRADABLE POLYMERS.In recent years, several studies have been developed in Brazil to produce biodegradable materials.A particular family of bacterial polymers, the polyhydroxyalkanoates (PHA), has received special attention.PHAs are thermoplastic, biodegradable, biocompatible, are synthesised from renewable resources and can substitute petrochemical plastics in some applications.Different aspects have been focused to increase productivity and to reduce the cost of PHA production: bacterial improvement, use of industrial by-products as raw material, bioreactor design, process operation strategies, downstream process, mathematical modelling, polymer characterisation, application and biodegradability of blends.A production process was transferred to industry and studies to produce new PHA by controlling monomer composition are in progress.All these aspects are presented in this review.
