Palm Biomass-Based Bioplastics as a Substitute for Petroplastics

---

Bioplastics provide a vital solution to the global environmental crisis caused by surging petroplastics production and consumption. Since 1950, global petroplastics output has risen exponentially from about 2 million tons to 475 million tons by 2022. While dominated by five major producers—China, the United States, India, the European Union, and Japan—Indonesia is also a significant consumer, with rising import volumes. Petroplastics pose severe problems: they are fossil-derived, non-renewable, and emit large amounts of carbon dioxide during production.

Moreover, petroplastics are non-biodegradable, requiring over 450 years to decompose naturally. As a result, waste continues to accumulate—polluting rivers, oceans, and soil. An estimated 50–70 trillion pieces of petroplastic waste contaminate global waters, a figure projected to triple by 2040. Recycling efforts remain largely ineffective, as 85% of annual global petroplastics consumption ends up as waste. This underscores the urgent need for plastics that are both renewable and biodegradable. Palm-based bioplastics present themselves as a critical substitution pathway.

What Advantages Do Palm Bioplastics Offer Across the Supply Chain?

Palm biomass–based bioplastics hold several competitive advantages over petroplastics, particularly for a sustainable supply chain.

1. Abundant and renewable feedstock – Palm biomass, including empty fruit bunches, shells, fibers, trunks, and fronds, yields 80.1–95.9 tons of dry matter per hectare annually. With global oil palm plantations spanning 27.4 million hectares in 2024, biomass availability is estimated at 2.16–2.6 billion tons annually. This ensures year-round supply at low cost.
2. Low carbon footprint – Palm bioplastics can reduce carbon emissions by 30–70% compared to petroplastics. If 65.8% of global petroplastics were replaced, greenhouse gas emissions could drop by 241,000–316,000 tons of CO₂-equivalent.
3. Biodegradability – Unlike petroplastics (≈500 years degradation time), palm bioplastics decompose naturally in days to months, depending on type. For instance: Thermoplastic Starch (72–726 days), Polyhydroxyalkanoates (15–280 days), Polylactic Acid (28–98 days), Cellulose-Based Polymers (14–154 days), Protein-Based Polymers (36–50 days).
4. No food–fuel conflict – Palm biomass does not compete with food sources, making it a “green feedstock” integral to circular economy principles.

Research under GRS has demonstrated palm biomass conversion into bioplastics such as Polybutylene Succinate (PBS), Polylactic Acid (PLA), Polyhydroxyalkanoates (PHA), and Polyhydroxybutyrate (PHB), substituting for conventional plastics like Polyethylene (PE), Polypropylene (PP), and Polystyrene (PS).

What Technological Innovations Drive Palm Bioplastics Development?

Key innovations supported by BPDPKS’s GRS Program include:

• Feedstock utilization – Empty fruit bunches, shells, mesocarp fibers, trunks, and fronds—rich in cellulose, hemicellulose, and lignin—are harnessed as raw materials.
• Lactic acid production – Cellulose from empty fruit bunches is converted into lactic acid, a precursor for Polylactic Acid (PLA).
• Polymer diversification – Research has successfully produced PBS, PLA, PHA, and PHB from palm biomass, enabling substitution across multiple applications.
• Degradation studies – Extensive testing has provided benchmarks on biodegradation rates, crucial for tailoring bioplastics to end-of-life needs.

These breakthroughs confirm the technical feasibility and scalability potential of palm bioplastics as sustainable petroplastic substitutes.

What Business Models and Policies Can Facilitate Palm Bioplastics?

A successful transition requires integrated business models and policy frameworks. Indonesia generates about 6.8 million tons of petroplastic waste annually, with a national goal of zero petroplastic pollution by 2040. Achieving this requires structural policy measures.

Two key strategies are proposed:

1. Domestic Bioplastics Mandate – Obligating producers to blend petroplastics with palm bioplastics at increasing rates, ensuring a stable domestic market.
2. Petroplastics Import Levy – Applying differentiated tariffs on raw materials versus finished petroplastic products, with higher rates for the latter. Revenues can fund further R&D, incentivize domestic investment, and accelerate industrial scaling.

Indonesia’s success with mandatory biodiesel blending provides a model. Integrating a bioplastics mandate with a progressive import levy can decisively end the petroplastics era and usher in renewable, biodegradable, and sustainable palm-based alternatives.

Challenges and Opportunities

Challenges

1. Scaling up production – Moving from pilot to industrial scale requires heavy investment in infrastructure and technology.
2. Production costs – Currently higher than petroplastics, requiring further innovation and economies of scale.
3. Standards and certification – Lack of global uniformity creates barriers for adoption.
4. Market awareness – Limited public and industrial knowledge about bioplastics benefits.
5. R&D gaps – More research needed on durability, mechanical strength, diverse applications, and end-of-life behavior.

Opportunities

1. Global positioning – Palm bioplastics strengthen Indonesia’s image as a sustainability leader while opening export opportunities.
2. Large market potential – Growing global demand for eco-friendly alternatives.
3. Policy momentum – Strong government support through mandates, levies, and incentives.
4. Waste valorization – Turning palm oil biomass into high-value products enhances circular economy practices.
5. Sustained innovation – Advances in biotechnology and materials science expand applications.

Conclusion

The massive accumulation of petroplastic waste poses a critical global threat. Transitioning to palm biomass–based bioplastics is both urgent and feasible. With renewable, biodegradable, and sustainable properties, palm bioplastics present a transformative solution to petroplastics dependency.

Technological breakthroughs under the GRS Program prove their viability. To accelerate adoption, Indonesia must integrate mandatory palm bioplastics blending and a petroplastics import levy, ensuring a stable domestic market, reducing imports, and funding innovation.

By adopting these measures, Indonesia can lead the shift away from unsustainable petroplastics toward a renewable, circular, and sustainable bioplastics future.
