Factors affecting the economics of polyhydroxyalkanoate production by bacterial fermentation

Start a Research on Biopolymer Polyhydroxyalkanoate (PHA): A Review

“…It has been estimated that at least 30% or more of PHA cost is attributed to carbon, nutrients and aeration cost [115]. This has prompted intensive research to diversify PHA production from cheaper carbon sources and waste carbon as a means to lower PHA cost [45].…”

Agrowaste-based Polyhydroxyalkanoate (PHA) production using hydrolytic potential of Bacillus thuringiensis IAM 12077

“…This high cost of polymer production is the major bottleneck in the commercialization of biodegradable plastics. However, process economics reveal that the use of inexpensive and renewable carbon substrates such as agro-industrial wastes and by-products as feedstock can contribute to as much as 40-50% reduction in the overall production cost (Choi and Lee 1999;Kim and Chang 2000), and therefore can serve as a potential alternative to traditional carbon sources such as glucose (Hocking and Marchessault 1994;Steinbuchel and Fuchtenbusch 1998;Ojumu 2004). PHA can also be produced by fermentation using inexpensive raw materials, making its commercial production economically feasible (Oliviera et al 2004;Sentil and Prabakaran 2006;Chariramjus 2008;Ramdas et al 2009;Pal et al 2009;Ghate et al 2011).…”

Whey Lactose as a Raw Material for Microbial Production of Biodegradable Polyesters

“…Despite the huge efforts globally devoted to biopolymer research, PHAs are still not really competitive to petrochemical plastics mainly considering production costs and, to a certain extent, also regarding the material properties (Choi & Lee, 1999;Sudesh & Iwata, 2008;Koller et al, 2010). A major share of up to half of the entire production costs is related to the carbon substrates.…”
