“…The raw material cost calculated is comparable with the literature value of 0.118 and 0.149 USD$/ kg for crude and refined glycerol, respectively (Posada et al 2011). As the by-product in biodiesel synthesis, glycerol's price reduces drastically following the rapid growth of biodiesel industry and has huge potential as carbon source for PHA biosynthesis (Posada et al 2011). Being the unwanted waste from food industry, WCO also demonstrates its value as substrate for PHA production (1.180 USD$/kg PHA).…”

“…From Table 3, it is clearly shown that crude glycerol (0.362 USD$/kg PHA) is the most economic competitive substrate, followed by refined glycerol (0.484 USD$/kg PHA) as they gave a better biopolymer yield compared to others.

Being biodegradable and renewable, polyhydroxyalkanoates (PHAs), a green polymer, attract much attentions as potential alternative for conventional plastics due to increased concern towards environmental issue and resource depletion. However, PHAs not only have suffered some economic disadvantages on the market, and its environmental-friendliness has also been questioned as well. Therefore, there is a growing demand to improve both economic and environmental performances of PHAs production, especially at earlier stage of the process where there are plenty of opportunities and the modification cost is cheap. Therefore, a preliminary integrated assessment is introduced to provide a rapid evaluation for PHAs biosynthesis at R&D stage by coupling material cost analysis together with lifecycle assessment. Using fuzzy approach multi-objective optimization, crude glycerol is the most optimum substrate for biopolymer productions from Cupriavidus necator. The insight from sensitivity analysis has showed that the integrated assessment is sensitive to fluctuation in price and yield of substrate, while maintaining its robustness as similar result is obtained when using different multi-objective optimization tools. Providing some novel insights on PHAs biosynthesis like performance and site selection influencing factor, the integrated assessment can be used to facilitate screening for large-scale production of PHAs.

“…This value is significantly lower than technoeconomic assessments on other substrates, for example glucose (~47%) (42) or sucrose (~30%) (12). However, methane contributes significantly more than waste sources such as glycerol (~8%) (43). PHA from methane is therefore sensitive to gas prices, which are currently falling, particularly in the United States.…”

AbstractA major obstacle preventing the large scale production of polyhydroxyalkanoates (PHAs) has been the lack of a reliable, low cost, large volume feedstock. The abundance and relatively low price of methane therefore marks it as a substrate of interest. This paper presents a technoeconomic assessment of the production of poly-3-hydroxybutyrate (PHB) from methane.ASPEN Plus was used for process design and simulation. The design and economic evaluation is presented for production of 100,000 t/a PHB through methanotrophic fermentation and acetone-water solvent extraction. Production costs were estimated at $4.1-$6.8/kg PHA, which compares against a median price of $7.5/kg from other studies. Raw material costs are reduced from 30-50% of production for sugar feedstocks, to 22% of production for methane. A feature of the work is the revelation that heat removal from the two-stage bioreactor process contributes 28% of the operating cost. Thermophilic methanotrophs could allow the use of cooling water instead of refrigerant, reducing production costs to $3.2-5.4/kg PHA; it is noted that PHB producing thermophilic methanotrophs are yet to be isolated. Energy consumption for air compression and biomass drying were also identified as significant capital and operating costs and therefore optimisation of bioreactor height and pressure and biomass moisture content should be considered in future research.3
