Abstract
Polyhydroxyalkanoates (PHAs) are very promising materials which might serve as environmentally-friendly alternative to petrochemical plastics. The main obstacle preventing PHAs from entering the market massively is the final cost of the polymeric material, important portion of which is attributed to carbon substrate. Hence, the researchers have been intensively looking for cheap substrates enabling sustainable production of PHAs. Hence, this chapter summarizes the advances in biotechnological production of PHAs from various waste products originating from industries of different fields, especially from food industry and agriculture.
Keywords: Agricultural waste, Biodiesel industry, Biotechnological production, Carbon-rich waste, Cheese whey, Glycerol, Inexpensive substrates, Lignocelluloses, Lipid substrates, Molasses, Polyhydroxyalkanoates (PHA), Sugar industry, Upstream processing.
