Abstract:

The development of PHA industrialization was promoted through using the kitchen waste as feedstock to produce VFAs. This not only increase a new pathway for kitchen waste resource utilization, but also significantly reducing the cost of PHA products. This paper introduced the application fields and product types of PHA and summarized the technological process of PHA production using the kitchen waste. The mechanisms for the kitchen waste anaerobic acidification and PHA production were also analyzed. Furthermore, the effects of technological factors on the acidification phase of kitchen waste and the PHA enrichment and accumulation phase were discussed systematically. Finally, some outlooks on the development of PHA production from the kitchen waste were provided.

Key words: polyhydroxyalkanoate, kitchen waste, volatile fatty acid, microbial synthesis, degradable plastic
