Palm Oil Replanting Movement and Utilization of Biomass Waste

Palm oil trees begin to lose productivity after 20 years and need to be replaced after 25 years, while new trees take about four years to begin bearing fruit. This generally renders the land unproductive during this four-year period, which discourages farmers from replanting their palm oil. However, intercropping during this period can still provide benefits for farmers. Planting short-term crops like upland rice and corn alongside palm oils can help farmers earn additional income while the palm oils bear fruit and mature.

In 2024, Malaysia, the world's second-largest palm oil producer, began implementing land intensification due to limited land area, only replanting 2%, or approximately 114,000 hectares. This is despite the country's target of replanting 5% of its land. The situation in Indonesia is not much different, with replanting predicted to be less than 2%. For example, if only 1.5%, or approximately 246,000 hectares, are replanted, it would be disproportionate to the area of ​​its oil palm plantations, which is nearly three times Malaysia's. Furthermore, replanting should be carried out periodically every year to achieve optimal palm oil production performance.

The reluctance or slow pace of replanting has led to a decline in national crude palm oil (CPO) production. Malaysian palm oil production has even stagnated for more than a decade due to limited land for new plantations and slow replanting. Meanwhile, in Indonesia, concerns about deforestation have also impacted the expansion of new oil palm plantations. Crude palm oil (CPO) production will decline further if labor shortages and the spread of ganoderma fungus reduce yields.

Given the above conditions, the replanting of palm oil plantations must be encouraged to maintain or even increase palm oil production. The issue of biomass waste from palm oil trees, which cover thousands of hectares, also poses a challenge. With such a large volume of old palm oil trees, utilizing them for value-added products is crucial. With an average hectare of palm oil plantations containing 125 trees, each tree yielding an average dry weight of 2 tons, this yields 250 tons of dry weight of biomass per hectare. For 10,000 hectares, this yields 2.5 million tons of dry weight, and for 100,000 hectares, this yields 25 million tons of dry weight. An optimistic estimate would be that Indonesia could replant 5% of its land, or 820,000 hectares, for 205 million tons of dry weight of biomass. Similarly, Malaysia, with 5% replanting, or 285,000 hectares, would yield 71.25 million tons of dry weight.

Business readiness factors, both in terms of technology and the market or user base for the product, need to be carefully assessed. With such a large volume, biomass processing plants or industries can be established and operate optimally without worrying about raw material shortages. Products such as pellets, briquettes, and biochar are made from waste biomass from old palm oil trunks. Dead old palm oil trunks, often left abandoned on land, should be utilized to produce these useful, value-added products.

Biochar for Sustainable Palm Oil Productivity

The Indonesian government emphasized the importance of sustainable palm oil productivity for food and energy security, as conveyed by Deputy Minister of Agriculture Sudaryono, at the opening of ICOPE (International Conference on Palm Oil and Environment) in Sanur, Bali, mid-February 2025. The conference, attended by delegates from various countries, namely Indonesia, Malaysia, India, the Netherlands, France, Finland, Colombia, and Spain, aims to formulate a sustainable transformation for the palm oil industry. Sustainable palm oil productivity can be increased by land intensification and the use of superior seeds. Even if land expansion is necessary, it must be done without causing deforestation. Meanwhile, for replanting in dry land, it can also be combined with upland rice or corn through intercropping methods.

Biochar is a powerful solution
Palm oil productivity can be increased by improving fertilizer efficiency, or Nutrient Use Efficiency (NUE), as part of land intensification. Using the same fertilizer dose with the addition of biochar will increase palm oil productivity by around 20% or more. Fertilizer savings of around 30% with the addition of biochar will keep palm oil productivity relatively stable or at the same level as before. For efforts to increase palm oil productivity while avoiding deforestation, the first option is more appropriate: maintaining the same fertilizer dose as usual, but adding biochar to increase fertilizer efficiency.  

Indonesia's current CPO production reaches approximately 50 million tons/year across 16.4 million hectares, with an average CPO production of 3.55 tons/ha per hectare, or 3.55 million tons per million hectares. If biochar is used and productivity increases by 20%, this means an increase of 10 million tons of CPO per year (a total of 60 million tons of CPO per year), saving approximately 2.8 million hectares of land. The use of biochar will also slow down forest clearing (deforestation) for palm oil plantations.

Besides using biochar to increase palm oil productivity, other benefits from biochar production include the potential for carbon credits (BCR = biochar carbon removal) and the utilization of pyrolysis byproducts for palm oil plantations and palm oil mill operations in CPO production. This method offers several advantages for palm oil companies, such as savings in liquid organic fertilizer and pesticides, and the sale or export of 100% of the palm kernel shells (PKS). In addition to palm oil companies producing their own biochar through pyrolysis, it is also possible to establish separate companies or companies that collaborate with palm oil companies for biochar production under specific agreements.

Global pressure and scrutiny on the palm oil industry to adopt sustainable practices are increasing. Amidst soaring demand for palm oil in both global and domestic markets, increasing palm oil productivity is inevitable. Utilizing biomass waste from palm oil mills and plantations, such as empty fruit bunches (EFB) and trunks (OPT), for biochar production, and using biochar to increase palm oil productivity, is a powerful solution to address these challenges. Even for replanting dryland with upland rice or corn using intercropping methods, the use of biochar will also have a positive and significant impact on these intercrops.
