Zero Waste, All Parts Of Oil Palm Trees Utilized

6 menit baca

Oil palm is not just the source of vegetable oil. It is also an integrated bioindustry capable of converting 100% of its biomass into high-value products. From every ton of palm fresh fruit bunches (FFB) only around 22% can be extracted as vegetable oil, while the remaining 78% is biomass, which is often considered waste, despite having economic potential of up to US$ 150-200 per ton¹.

With its zero-waste concept, oil palm is the backbone of a circular economy and a model for future agro-industrial sustainability.

It means that to produce the same amount of vegetable oil, oil palm tree requires 9x less land than soybeans. That is the key to sustainability in an era of land constraints.

Zero Waste concept in oil palm

Zero waste in oil palm means that all biomass from palm plantations and mills is recycled into useful products. Nothing is wasted. This concept aligns with:

  • Circular Economy – maximizing resource utilization
  • Biorefinery – integrated biomass processing for various green products
  • Sustainable Development Goals (SDGs) – specifically SDGs 7, 12, 13, and 15²

Utilization of all parts: A to Z

Oil PALM BIOMASS TRANSFORMATION FLOW

Palm fruit flesh and palm kernel (22% of fresh fruit bunches –FFB)

Processing results:

  • Crude Palm Oil (CPO) → 200-220 kg per ton FFB
  • Palm Kernel Oil (PKO) → 40-50 kg per ton FFB

Final Products:

  • Food Products – cooking oil, margarine, shortening
  • Toiletries & cosmetics – soap, shampoo, lipstick, cream
  • Biofuel – biodiesel B30, B40, up to B100
  • Oleochemical – fatty acid, glycerin, surfactant

Advantages: Oil palm has productivity of 3.8 ton/ha/year, highest in the world—9.5x more efficient than soybean ⁴⁵.

Palm shells (5-7% of FFB)

Potential: Every palm oil mill produces 50-70 kg of palm shells from every ton of FFB

Utilization:

  • • Boiler fuel – calorific value 4,000-4,500 kcal/kg (equivalent to 60% of coal)
  • • Biomass power generation – 1 ton of shells → 800-1,000 kWh of electricity
  • • Environmentally friendly concrete aggregate – gravel replacement, weight reduction 15-20%
  • • Activated carbon – adsorption capacity up to 1,000 mg/g, for water and industrial filters
  • • Battery electrodes – lithium-ion anode material research
  • Environmental Impact: Replacing coal with palm kernel shells reduces CO₂ emissions by up to 2.5 tons per ton of shells⁶.

Empty palm bunches (23% of FFB)

Biggest potential: Every palm oil mill produces 230 kg empty palm fruit bunches (TKKS) from every ton of FFB = 15-20 ton TKKS per hectare per year

TKKS transformation:

Organic fertilizer & compost

  • Direct application to plantations (mulching) or composted
  • Reduce need of chemical fertilizer up to 30-40%
  • Increase land carbon stock up to 15 tons of CO₂e/ha⁷

Bioenergy

  • Bioethanol – potential 150-200 liter per ton of dry TKKS
  • Bio-crude oil – via pyrolysis, yield 35-45%
  • Biogas – potential 200-300 m³ per ton of TKKS

Industrial Material

  • Bioplastics (PHA/PHB) – 100% biodegradable in 6-12 months
  • • Pulp & paper – wood-like quality, 40-50% yield
  • • Paper bags & packaging – alternatives to single-use plastics
  • • Particleboard & MDF – substitutes for forest wood

Integrated Biorefinery

OPEFB is an ideal raw material for a cascade biorefinery, where a single material is processed in stages to produce multiple products:

Economic value: Used to be waste, now TKKS is worth US$ 15-25 per ton (compost) up to US$ 150-200 per ton (bioethanol & bioplastics)⁷.

Fronds

Potential: 22-24 fronds per palm tree per year × 130-150 trees/ha = 2.800-3,600 fronds/ha/year (≈ 25-30 ton biomass)

Utilization:

  • Organic fertilizer – returned to the soil as mulch
  • Bioenergy – charcoal briquettes with a calorific value of 3,500-4,000 kcal/kg
  • • Animal feed – after fermentation, crude protein increases from 4% to 12%
  • • Woven crafts – bags, hats, decorations
  • • Particleboard – raw material for furniture
  • Social Impact: Utilization of oil palm fronds opens up micro-enterprises and village economies based on crafts and animal feed.

Palm trunks (from replanting)

Potential: Each replanting cycle (25 years) produces 200-250 tons of trunks per hectare.

Palm Oil Trunk Transformation:

  • Furniture & wood products – quality equivalent to sengon wood (Albizia chinensis)
  • Construction materials – beams, boards, plywood
  • Bioethanol – potential 80-100 liters per ton of trunks
  • Pulp & paper – yield 45-50%, brightness 70-75%
  • Composite board – OSB (Oriented Strand Board)

Environmental Significance: Using palm trunks reduces pressure on natural forests as a source of conventional wood. Indonesia conducts replanting of approximately 200,000 hectares of oil palm plantation per year, resulting in 40-50 million tons of trunks that can replace forest wood.

Positive Impacts of palm zero waste

Environment:

  • Reduce GHG emissions by 3-5 tons of CO₂e per hectare per year
  • Reduce factory waste by up to 90%
  • Reduce dependence on fossil fuels
  • Increase carbon sequestration in plantation soil

Economy

  • Biomass value added: from US$ 0 → US$ 100-200 per ton
  • Creates 15-20 new jobs per 1,000 tons of fresh fruit bunches (FFB)
  • Product diversification = lower market risk
  • Global bioplastics market potential of US$ 20 billion by 2030

Social

  • Empower local economies based on small and medium businesses (UMKM)
  • Technological transfer to plasma farmers
  • Increase image of sustainable palm oil industry

Innovation & Future Prospect:

  1. Nanocellulose from OPEFB – a super-strong material for composites and electronics
  2. Hydrogen production – gasification of palm biomass for hydrogen energy
  3. Biosurfactant – a substitute for chemical detergents from PKO
  4. Quality animal feed – high-protein palm frond silage
  5. Premium biochar – carbon capture and soil amendment

Target 2030:

  • 100% palm oil biomass utilized (zero waste)
  • 30% of mill energy from own biomass
  • Exports of biomass-derived products worth US$ 2-3 billion
  • Carbon-negative certification for sustainable plantations
  • Palm oil is a perfect example of a circular economy: nothing is wasted, everything has value. From every ton of fresh fruit bunches (FFB), we obtain not only 220 kg of oil, but also 780 kg of biomass that can be used as energy, fertilizer, materials, and green products.
  • With continuous innovation, oil palm tree is not just an oil producer—it is a catalyst for Indonesia’s bioeconomy towards a net-zero emissions future. (*)
