Introduction

The bio-based polypropylene market is positioned for steady growth as industries increasingly shift from fossil-derived plastics toward renewable alternatives. According to Stratview Research, the bio-based polypropylene market is expected to grow from around USD 39.42 million in 2022 to approximately USD 53.21 million by 2028, representing a CAGR of about 5.1% over the forecast period. Bio-based PP is manufactured from renewable biomass feedstocks and offers the same performance as conventional PP while contributing to reduced fossil-fuel dependency and lower carbon emissions.

Applications

Bio-based polypropylene finds usage across injection moulding, films, textiles and other plastic components. Stratview identifies the injection application type (e.g., automotive interior and exterior parts) as expected to see heightened demand during the forecast period. Because bio-PP can be used as a drop-in replacement for traditional PP, it is particularly attractive in sectors such as automotive, packaging and consumer goods that are under pressure to incorporate sustainable materials.

Key Drivers

Several drivers underpin growth in this market. First, growing regulatory pressure and consumer demand favouring lower-carbon materials are prompting adoption of bio-based polymers. Stratview cites favourable regulations aimed at reducing carbon emissions and boosting use of renewable materials. Second, the automotive industry’s focus on lightweighting and material substitution to improve fuel efficiency supports bio-PP uptake. Third, feedstock diversification from biomass offers companies a route to differentiate and meet sustainability goals.

Future Opportunities

Key opportunities lie in expanding end-use segments and geographies. Asia-Pacific is expected to remain the largest region for bio-PP during the forecast period, driven by significant manufacturing bases and biomass availability. Further, the extension of bio-PP into high-value applications—such as automotive exterior parts, films for packaging, and textile nonwovens—offers upside. Innovations in feedstock sourcing, certification of bio-content and cost reduction will further open the way for broader adoption.

Conclusion

In summary, the bio-based polypropylene market offers a promising but measured growth path. With its performance parity with conventional PP and benefits in sustainability, bio-PP is increasingly relevant. Although its absolute market size remains modest (starting from tens of millions of USD per Stratview’s figures), companies investing early in feedstock, production scale-up and end-use partnerships are well-placed to capitalize on the transition toward renewable plastics.
