Activated sludge plant application area

Low-cost PHAs would not only benefit the PHA material application as bioplastics, but promote the application of PHAs as biofuels as well. There is a large potential for compromise in this area, as low-cost PHAs could also be obtained from activated sludge and wastewater fermentation, so it will not run into the controversy of food versus fuel or fuel versus arable land. Plant production of PHAs could become a reality, as indicated by some promising results, in the foreseeable future.
