Slowing Palm Oil Land Expansion: Replanting or Biochar ?

The reckless expansion of palm oi plantations is definitely offside sustainability. Instead of palm oil being a blessing due to their highest productivity among other vegetable oil sources (soybeans, sunflowers, rapeseed, coconuts, etc.), growing only in tropical regions and contributing 40% of the global vegetable oil supply, they have instead become a natural disaster. The cost of this disaster is no small matter, costing thousands of lives, in addition to other material losses. This issue was particularly highlighted during the recent floods in Sumatra. Are the profits from palm oil worth the loss of life?

Clearing tens or even hundreds of thousands of hectares of oil palm plantations produces valuable timber. It's even possible to generate substantial profits from land clearing alone, even though palm oil plantations and production haven't even begun. This is what drives entrepreneurs to flock to this plantation sector, driven by the sole goal of maximizing profits without considering their own needs, resulting in widespread disasters. Furthermore, the implementation of mandatory B-40 or even B-50 biodiesel, currently being discussed, will undoubtedly create a new market for palm oil/CPO, much easier and more flexible than exporting to Europe, which is subject to the European Union Deforestation Regulation (EUDR), or to the US, which faces high tariffs.

Moreover, it has already been established that palm oil/CPO consumption for biodiesel has exceeded food demand. The mandatory implementation of the B-50 program also requires a 20% increase in CPO production capacity, or 60 million tons per year. The most profitable and fastest way to do this is through extensive deforestation, as the timber from cleared forests can be sold directly.

When the goal is to increase palm oil production gradually, safely, in a planned, and sustainable manner, adequate consideration is required, not blindly and recklessly clearing forest areas (deforestation) under the guise of land conversion. Besides the use of superior seeds, there are at least two ways to increase palm oil productivity: replanting and biochar application (part of land intensification).

According to Joko Supriyono, former chairman of GAPKI (Indonesian Palm Oil Producers Association) for the 2015-2018 and 2018-2023 periods, in his book "Is Indonesian Palm Oil Still Successful?", it is stated that if replanting of palm oil in Indonesia successfully reaches 300 thousand hectares per year, it is estimated that CPO and CPKO production in 2045 will reach 80 million tons. While currently CPO and CPKO production is around 55 million tons. And with the use of biochar, palm oil productivity will increase by an average of 30% in 5-10 years, meaning that by 2035 CPO and CPKO production will reach 71.5 million tons. Moreover, if the two methods are combined, the results should be even better.

Indonesia's current CPO production reaches approximately 50 million tons/year, covering a land area of ​​16.8 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 30%, this means an increase of 15 million tons of CPO (a total of 65 million tons of CPO/year) and this saves approximately 4.2 million hectares of land, or the use of biochar will slow down forest clearing for palm oil plantations. The application of biochar with compost will improve the quality of the compost to become premium compost. For more details, read here. This allows the palm oil industry to operate by utilizing all its biomass waste.

The replanting movement of palm oil plantations must be encouraged to continuously increase palm oil production. The problem 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 consisting of 125 trees, each tree having an average dry weight of 0.4 tons, this yields 50 tons of dry weight of biomass per hectare. For an area of ​​10,000 hectares, this yields 0.5 million tons of dry weight, and for an area of ​​100,000 hectares, this translates to 5 million tons of dry weight. An optimistic estimate suggests that Indonesia could achieve 5% replanting (very optimistic) or 820,000 hectares, which would yield 41 million tons of dry weight of biomass per year. Similarly, Malaysia, with 5% replanting or 285,000 hectares, would produce 14.25 million tons of dry weight per year.

Business readiness factors, both technologically and in terms of the market or user base, 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, biochar, and other bioproducts, such as other biocarbons, biomaterials, biofuels, and biochemicals, are also possible from this old palm oil trunk biomass waste. Old, dead oil palm trunks, often left unattended on land, should be utilized to produce these useful, value-added products.

AI for Palm Oil Mills or New Product Development with New Process Design?

AI applications have penetrated various sectors, including palm oil mills or CPO mills. AI applications for palm oil mills are still relatively new, so few, if any, have implemented them. One palm oil mill that has implemented AI is Minsawi Industries in Kuala Kangsar, Malaysia, with a capacity of 45 tons of fresh fruit bunches (FFB) per hour. The use of AI has resulted in annual savings of RM 1.6 million (Rp 6.24 billion) due to reduced oil loss, reduced maintenance costs, and a 33% reduction in labor. However, there are concerns that using AI for palm oil mills could potentially lead to job losses. Even with fewer workers, incomes are higher.

The cost-to-benefit ratio is certainly a crucial consideration for any new technology, including the use of AI. The amount of money spent must yield equivalent or greater benefits. In the case of the AI ​​application in the palm oil mill, the cost of the AI ​​was RM 5 million (~Rp 19.5 billion), meaning that with savings of RM 1.6 million per year, the investment in the AI ​​equipment would be recovered in approximately three years. This is a reasonable return on investment. However, investing that much to improve efficiency in an existing mill, or for example, 15% of the main mill, requires comprehensive consideration.

Several devices, such as sensors, predictive tools, and AI applications, are integrated to improve the efficiency of palm oil (CPO) production. More specifically, the key components of an AI-based palm oil mill include: first, advanced sensors. These sensors are installed throughout the palm oil mill to obtain real-time data on critical parameters such as temperature, pressure, amperage, and machine performance. Second, AI-enabled CCTV cameras. Several cameras are installed at strategic locations to monitor key areas, such as detecting the volume of fresh fruit bunches (FFB) and their quality, and providing this information to control the production process. Third, an AI-driven control system. These systems automatically optimize processes, manage equipment operations, and utilize resources based on real-time data analysis.

Meanwhile, developing new products means increasing the added value of existing materials. This increased added value can be far greater than that gained from increasing factory efficiency through AI applications. Raw materials that were previously underutilized or even discarded, polluting the environment, can generate significant benefits from developing new products. While optimizing factory performance is crucial for achieving high efficiency, innovation in new product development is equally crucial.

In the palm oil industry, new product development can be achieved by creating various derivatives from crude palm oil (CPO) and processing various biomass waste from palm oil operations, both from mills and plantations. Numerous products can be produced from these processes. For example, CPO derivatives produce biofuels such as biodiesel, cooking oil, stearin, olein, and so on. Biomass waste can be processed into bioenergy, biocarbons, biofuels, biomaterials, and biochemicals.

 

Designing efficient production processes is crucial for producing competitive products. Likewise, low-emission production, minimizing waste, or even zero waste, is also a key focus. Integrating various production processes, particularly for energy savings, including waste heat recovery, is highly feasible, enabling efficiency and lower production costs. The significant benefits of AI applications in palm oil mills or CPO production include the potential for further use in new product development, including designing the most efficient production processes possible.

Ultimately, if the development of these new products can be carried out and AI is integrated, the need for labor will increase in these business units, even if each business unit is operating efficiently. The production of various derivative products, including specialty chemicals, is highly possible with the development of new products that keep pace with the times. Furthermore, on the plantation side, AI and mechanization can also be utilized to reduce 3D (dirty, dangerous, demeaning) jobs, resulting in more efficient work and increased income. Even mechanization in oil palm plantations is still low, making it more urgent than AI applications. 

Replanting Palm Oil Plantations and Utilizing Old Palm Oil Trunks Waste (Presentation Version)

Aging plants are one factor in declining palm oil productivity. Palm oil trees begin to decline in productivity after 20 years and need to be replaced after 25 years. Therefore, rejuvenation or replanting must be carried out periodically according to the age of the trees.

Furthermore, the demand for palm oil continues to grow in line with global population growth. For the domestic market, biofuel use takes the form of a mandatory 40% palm oil blend in biodiesel (B40) this year, which is being reviewed to increase to 50% (B50) by 2026, and a 3% blend for jet fuel by 2026. Demand for the international market also continues to grow. The main destinations for Indonesian palm oil are India, China, Pakistan, Bangladesh, the United States, the Netherlands, Spain, Italy, Egypt, and South Africa.

Replanting palm oil plantations is crucial because it maintains sustainable palm oil productivity and prevents or reduces deforestation for new lands. The potential volume of old palm oil trunk waste generated is enormous, and there are numerous utilization options, including bioenergy, biocarbon, biomaterials, biofuels, and biochemicals.

Bioeconomy in a Tropical Country “Biomass Heaven”

Indonesia is believed to be a tropical country of biomass heaven so this needs to be translated into a more concrete form so that it can be understood, executed so that it is proven and the potential can be utilized optimally. There is so much potential that should be used to support the welfare of its people. The simple diagram below illustrates so many things that can be done in a tropical country "biomass heaven".

The availability of raw materials is a vital and absolute factor so that various biomass processing can be carried out and sustainable. On the other hand, there is a lot of land potentials that can be utilized for this purpose, the amount of which reaches tens of millions of hectares, namely critical land / marginal land, dry land and post-mining land (coal mines, tin mines, nickel mines, copper mines, gold mines and so on). In more detail, it is estimated that for critical / marginal land it reaches 24.3 million hectares (Times Indonesia, 2017) while dry land reaches 122.1 million ha consisting of dry acid land covering 108.8 million ha and dry climate dry land covering 13.3 million ha and post-mining damaged land reaching 8 million hectares. Energy plantations or biomass plantations need to be created in these land areas and can even be used for various food crops. Even now there are plant species that can only be economically viable on these lands.

Both energy and biomass plantations can be planted with various plants that support sustainable bioeconomy in line with decarbonization, including calliandra, gliricidia, bamboo, calophyllum inophyllum, coconut and even oil palm, including food crops such as rice, corn and soybeans. The selection of plant species will be adjusted to the product to be made, land conditions, and technological and business readiness.

Meanwhile, biomass waste that is currently produced annually, especially from the agricultural and forestry sectors, which also amounts to millions of tons, can be optimized so that in addition to reducing or avoiding environmental pollution, it will also provide added economic value, environmental and social benefits. The utilization of biomass, both from agricultural and forestry waste or from energy plantations and biomass plantations, will be a sustainable bioeconomy activity and in line with the global decarbonization trend that is in line with climate solutions.
 

Why is Wood Pellet Production use Wood from Energy Plantation and not from Natural Forest Wood?

Basically, all woody biomass can be used as raw material for wood pellet production, but the economic factor is the main limiting factor. That is why wood pellets are produced only from energy plantations and wood industry wastes, and not from natural forest wood. And basically for wood pellet production only uses wood industry wastes and energy plantations to achieve economic factors or in other words, the raw material for wood pellets is wood or wood waste that is worth like the wood waste. That is why wood from natural forests that are decades old are not suitable for use as raw material for wood pellets. The wood has a higher economic value so that if it is used for wood pellet production, the wood pellet product produced will certainly be expensive so that it does not sell in the market. Energy plantation using fast growing trees and coppice namely leguminoceae groups such as gliricidia and red calliandra, while natural forest wood uses plants that grow slowly so that it takes decades to be able to harvest or take the wood like teak trees.

Biomass or specifically wood is a material that can store carbon from the atmosphere. As long as it is in the form of wood, carbon is still stored in the wood. The longer the use of wood for various things in human life, the longer the carbon is stored in the wood material, and vice versa. A number of attempts were made to extend the life of the wood from a number of damages such as wood drying, use of wood preservatives and so on. Based on the above conditions, the carbon storage time in wood material can be grouped into two, namely, first, long-term storage, namely the use of wood for buildings, doors, windows, furniture, etc., and secondly, short-term carbon storage for use as fuel material or energy source. Wood pellets are the use of wood biomass as a source of energy, and because the wood is produced from photosynthesis, that is, trees absorb CO2 from the atmosphere, use water and sunlight to become material, especially when burned, carbon emissions do not increase the concentration of CO2 or greenhouse gases in the atmosphere, so it is termed as carbon neutral fuel.

In the forest management, namely for energy and wood plantations for industrial needs, whose age is up to decades, certainly has its own mechanism and characteristics. As the earth's temperature reduction program is due to climate change due to high atmospheric CO2 concentrations, biomass as a carbon neutral fuel is increasingly needed. Wood pellet needs are projected to reach tens of million of tons in the next few years. This should encourage the importance of increasing the number and extent of energy plantations for the production of wood pellets. The energy plantation for wood pellet production can be integrated with sheep, goat or cow farms, for more details, please read here. Whereas wood for industrial needs with decades of age for use in buildings, furniture and so on began to occur a lot of decline because many are replaced by other materials that are generally cheaper such as aluminum, mild steel and PVC. Wood materials for various purposes are also increasingly limited in their use. A number of environmental problems are also a concern when the wood is preserved mainly with the use of CCA (copper-chrome-arsenic). Although it will produce wood with good properties such as termite resistance, stable dimensions, high mechanical strength and so on but after it wears out and is no longer used and discarded, the wood will release arsenic and chromium into the atmosphere, so it is not environmentally friendly and dangerous.

Water Crisis, Bioeconomy and Climate Change

The water crisis is part of an environmental disaster that greatly affects the lives of all living things including humans. Environmental disasters such as the water crisis also have a cause. The main cause of this is due to environmental damage caused by human hands. If the environment is not maintained, a number of such disasters occur. Victims of the disaster not only affected the perpetrators of environmental destruction but also other communities. Deforestation so that the land becomes barren and arid is the main cause of the water crisis. In the dry season it results in a water crisis and in the rainy season has the potential for floods and landslides. Deforestation and illegal logging in general are closely related to economic interests and ignore environmental aspects.

During the dry season as it is today, many of us encounter areas that are drought and even some areas of forest fires occur. More technically and in detail the drought causes the decrease in the supply of clean water from water sources to decrease, the level of lake water or reservoirs to hold water, the wells to dry up as well as the rivers. A number of regions have even experienced a marked decline in water supply and levels. There is no living creature that can live without water, because water is a vital need for living things, even in the Qur'an it is explained that Allah SWT created living things from water (QS Al-Anbiya, verse 30), the human body itself 70% is water.

So many critical lands, marginal lands, up to idle lands that are not utilized, and these lands will be increasingly damaged such as desertification and the potential to cause various disasters. This should be utilized so that potential disasters can be minimized. Furthermore, these lands should also be able to provide economic benefits so that forest destruction can also be minimized. When the community has been able to be economically independent by utilizing these lands, the protected forest can be well preserved. The solution to environmental problems as well as economic aspects is the right solution and below there are 2 scenarios that can be done, namely first,bamboo plantation for biomaterials and energy plantations for biomass  energy supplies. Aside from deforestation, water crisis is also a result of climate change. The high concentration of CO2 in the atmosphere affects the climate change and the solution of making these plantations as well as a medium to absorb CO2 from the atmosphere.

Bamboo as Biomaterial
Bamboo trees are very familiar to almost all people and many people still use bamboo until now. But the use of bamboo is mostly still on a variety of products that have low added value so that it is economically less attractive. Bamboo trees also have great potential for large plantations with a top priority for environmental improvement and a second priority as a source of biomass feedstocks for biomaterials. Bamboo plantations are for environmental improvement because the plantations are able to prevent erosion, absorb CO2 from the atmosphere, O2 sources and are able to lift groundwater so that it helps the availability of water. Although basically all trees are able to absorb and retain water, but bamboo trees have the ability above average that can lift the surface of ground water an average of 10 meters in 20 years or 0.5 meters annually. The water crisis that occurs can be reduced or eliminated by making bamboo plantations.

Bamboo plantations are also very effective for the supply of biomass  for biomaterials. When the bamboo tree is 5 years old, every month from its clump, bamboo stems can be harvested every month until the productive period reaches 60 years without replanting. As for wood from other trees, it generally takes 10 years or even more to be harvested once and replanting it for the next cycle. Furthermore, the use of bamboo so as to produce high economic value products is an important thing to do. Products such as bamboo composites, bamboo textiles, and flooring, are a number of uses of bamboo with high economic value. The quality of bamboo composites is special as well as bamboo textiles. Imports of textile raw materials that are still dominant today can also be reduced with bamboo textiles. Bamboo plantation and processing can be a model of bioeconomy and for more details can be read here, as well as further bamboo as a biomaterial can be read here.

Energy Plantation to Supply Biomass Energy
Although currently almost all energy producers from biomass are limited to utilizing waste wood from wood working industries, sawmill and agricultural waste, but because the supply of these wastes is limited and fluctuating, it is difficult to be relie upon to supply for large capacity and sustainable. In the near future it is estimated that the energy plantation will replace it. Energy plantations with fast rotation plants are the ideal solution for supplying large amounts of energy and sustainability. Wood pellets are one of the products that can be made from these energy plantation. The demand for wood pellets in the international market is increasing along with the awareness onenvironmental problems. Wood chips as a simpler product can also be made if the user of the biomass fuel is close enough to the energy plantation.

On a smaller scale, wood from energy plantations can also be used for briquette and charcoal briquette production. Briquette needs are not as much as pellets and charcoal briquettes, especially only for barbecue. Charcoal briquette or more popularly known as sawdust charcoal briquette has a large market especially in the Middle East, Saudi Arabia and Turkey. Leaves from the energy plantation can also be used for animal feed, such as sheep, goats, cows and buffalo. The leaves also have a high protein content so that it becomes nutritious feed for these animals. Pasture can also be made in the energy plantation area so that the livestock business becomes effective and efficient, for more details, please read here. In terms of environmental aspects the energy plantation also plays a role in CO2 absorption, preventing erosion and water conservation. Even the roots of energy plantation plants that can absorb N2 from the atmosphere will increasingly fertilize the soil.

 If humans can make optimal use of the land to meet their daily needs by maintaining balance, caring for and not damaging it, then disasters such as water crises and landslides, InsyaAllah, will not occur. Utilize while maintaining the environment wisely so that it can continue to grow and be sustainable as well as a form of gratitude for the blessings of Allah SWT so that these favors are added by Him.
"If the inhabitants of the countries of faith and god fear, surely We will bestow upon them blessings from heaven and earth, but they deny (Our verses), then We torture them for their actions." (QS, Al A'raf: 96).
