Sažetak
A major reason for the call to increasingly switch towards polymers based on renewable resources is their presumed advantage regarding ecological performance compared to fossil competitors. Usually, this argument is based on the assumption that products based on renewable sources hold an inherent ecological advantage over products derived from other sources, in particular fossil sources. This claim however must be substantiated by looking into the ecological impacts accrued by the production of a material along the whole life cycle, from the raw material generation to the provision of the
final product. Only thorough life cycle assessments (LCA) can provide solid, comprehensive and quantifiable information about the ecological performance of products, and thus answer the question of any superiority of bio-polymers regarding their environmental impacts.
The paper will review the ongoing discourse about environmental performance of PHA in literature. It will also analyse the most important factors that decide about the ecological performance of PHA derived from different raw materials as well as the potential for improvement that is still available for PHA production.
