Based on data from 2018, the average price for PHA was US $8.0 per kg.
PHA (Polyhydroxyalkanoates) is generally significantly more expensive than common petroleum-derived plastics. According to a study of the global PHA market in 2018, the average price point for PHA was US $8.0 per kilogram.
To put this into perspective, conventional polymers like polypropylene and polyethylene typically have a price range of about US $1.25–2.53 per kg. The reference indicates that the price of PHAs has been reported to be up to 16 times higher than these major petroleum-derived polymers. The 2018 average of $8.0 per kg aligns with this comparison, being roughly 3 to 6 times the price of traditional plastics mentioned.
Here's a quick look at the price comparison based on the provided information:
| Polymer Type | Typical Price Range (US $/kg) | 2018 Average Price (US $/kg) |
|---|---|---|
| Polypropylene & Polyethylene | 1.25 – 2.53 | N/A |
| PHA (Polyhydroxyalkanoates) | Up to 16 times higher | 8.0 |
Note: The prices for polypropylene and polyethylene are typical ranges mentioned, while the PHA price is specifically the reported average for 2018.
This higher cost is a factor influencing the wider adoption of PHA bioplastics compared to traditional plastics, although prices can fluctuate based on production scale, specific PHA type, and market conditions.
