A market research report published in early 2025 puts the global bioplastics market at roughly $15 billion in 2025 and projects $119 billion by 2035, a compound annual growth rate near 23%. Forecasts this far out are worth reading as a direction rather than a number, and the direction of bioplastics market growth is set by regulation, brand commitments and falling production costs.
Note that market-value forecasts vary widely with which materials the analyst counts. European Bioplastics and the nova-Institute, working from production capacity rather than revenue, publish a more conservative picture, which we cover in Market & Trends.
Why the market is accelerating
For two decades bioplastics were a niche. Production capacity sat around 2 to 3 million tonnes a year against more than 400 million tonnes of conventional plastics. That changed after 2020, when single-use plastic bans, corporate commitments from Nestlé, Unilever and PepsiCo, and public attention to plastic pollution arrived at roughly the same time.
The technology matured in parallel. Production costs for polylactic acid (PLA), polyhydroxyalkanoates (PHA) and starch blends have fallen substantially. Bio-based versions of conventional polymers, bio-PE and bio-PET, attracted brand owners because they cut carbon footprint without touching a production line. Our Bio-based Polymers guide covers them in detail.
Where the growth sits
The forecast splits across material segments that are moving at different speeds.
- PLA remains the largest segment by volume, benefiting from expanded production capacity in Asia and Europe. Its versatility in packaging, textiles, and 3D printing keeps demand high.
- PHA is the fastest-growing segment, with analysts projecting it to capture a significantly larger market share by 2030 as fermentation-based production scales up.
- Starch blends continue to serve the compostable bags and food-service sectors, particularly in Europe where composting infrastructure is expanding.
- Bio-PE and Bio-PET appeal to the packaging industry as chemically identical alternatives to their fossil-based counterparts, enabling easier integration into existing recycling streams.
Three forces push all of them: regulation through plastic bans, extended producer responsibility and recycled content mandates; consumer demand, where surveys keep showing willingness to pay more for sustainable packaging; and material innovation in new blends, better barrier properties and cheaper processing.
What a market that size would change
If the projection holds, bioplastics take a materially larger share of the plastics market by 2035, and the effects run down the whole chain.
Agricultural producers of corn, sugarcane and cellulose gain a new demand stream. Chemical companies and compounders have to build dedicated bioplastics lines. Brand owners get a wider material portfolio to hit net-zero and circularity targets against.
None of that delivers environmental benefit without matching investment in end-of-life infrastructure. Compostable material with nowhere to be composted is just expensive plastic.
What to watch
New PHA plants planned for 2026 and 2027 in the United States, Europe and Southeast Asia will show whether commercial-scale fermentation can produce cost-competitive material, which is the question the whole PHA forecast rests on. Policy matters as much: the EU’s Packaging and Packaging Waste Regulation is being implemented now, and US federal legislation remains possible.
Second- and third-generation feedstocks from agricultural waste, algae and captured carbon dioxide could change the cost base while removing the land-use argument. Price parity with conventional plastics is still the variable that decides how fast any of this scales.
