Plant-based plastics, or bio-based plastics, are manufactured wholly or partially from renewable biomass sources like corn, sugarcane, and vegetable oils . This market segment is a critical part of the transition away from a fossil-fuel-based economy, offering materials that can help companies meet ambitious carbon reduction targets. The strong growth of this market is evident in corporate procurement and technological innovation.

The feedstock for plant-based plastics is diverse. In North America, corn is the dominant source, particularly for PLA, as it is one of the cheapest and most available sugars globally . In Brazil and parts of Asia, sugarcane is a key feedstock for bio-PE and ethanol-based processes . The use of non-food biomass and agricultural waste as a feedstock is an area of active development, aiming to avoid competition with food crops and further enhance sustainability .

The rise of plant-based plastics is being fueled by major brand commitments. Coca-Cola’s initiative to scale 100% plant-based PET bottles, and similar pledges from other FMCG giants, are sending strong signals to the supply chain . These commitments, combined with regulatory incentives like subsidies and tax breaks in countries such as India and Thailand, are accelerating capacity expansion and making plant-based plastics more competitive . The development of plant-based automotive parts is also an expanding opportunity .
