The rise of bioplastics has been predicted for two decades and is finally happening at a measurable scale, though not at the pace the forecasts suggested. Global bio-based plastics production capacity was around 2.31 million tonnes in 2025 against total plastics production of 430.9 million tonnes, which puts bioplastics at well under 1% of the market. That is real growth from a very small base rather than a replacement of fossil plastic.
The Rise of Bioplastics: What They Actually Are
The term covers two different things and conflating them causes most of the confusion around the rise of bioplastics.
Bio-based means made from renewable feedstock rather than fossil oil or gas. It says nothing about what happens at end of life. Bio-polyethylene from sugarcane is chemically identical to fossil polyethylene and just as persistent.
Biodegradable means it breaks down under defined conditions. Some biodegradable plastics are made from fossil feedstock, and most require industrial composting at controlled temperature rather than degrading in a hedgerow or the sea.
A material can be one, both, or neither. PLA is bio-based and industrially compostable. Bio-PE is bio-based and not degradable. PBAT is fossil-based and compostable.
Why the Rise of Bioplastics Has Been Slow
Price. Bioplastics cost more than commodity resins, typically 20% to 60% for PLA and considerably more for PHA. The gap has narrowed and has not closed.
Scale. Total capacity is a fraction of a percent of fossil plastic production, and it cannot simply be built quickly.
Performance. PLA softens at relatively low temperatures, which rules it out for anything hot-filled or used in a car. Many applications need properties bioplastics do not yet offer.
Infrastructure. Industrial composting is not universally available, so a compostable product often ends up in landfill or incineration where its compostability is irrelevant.
Feedstock competition. Bio-based feedstocks use agricultural land, which raises questions the industry has not fully answered.
Where the Rise of Bioplastics Genuinely Works
Food service items destined for industrial composting, agricultural films designed to break down in soil, packaging where a brand’s positioning justifies the cost, and drop-in bio-based versions of commodity resins where a company wants a lower carbon footprint without changing its process or performance.
Drop-ins are the underrated case: bio-PE and bio-PET mould on existing equipment with no process change, which removes the main practical obstacle.
Will the Rise of Bioplastics Replace Fossil Plastic?
Not soon, and probably not entirely. The more realistic picture is that bioplastics take specific applications where their properties fit, while recycled conventional plastic does more of the heavy lifting on reducing fossil feedstock use. Circular plastics as a whole, recycled and bio-based together, passed 10% of global production in 2024 (Plastics Europe), and recycled material is the larger part of that by far.
For a product company the practical position is to evaluate bioplastics application by application rather than as a principle. The article on bioplastic costs covers the pricing in detail, and selecting materials for a specific product is what our plastics production package covers.x
