Strengthening Sustainability Efforts by Reducing or Eliminating the Use of Chemicals in Palm Oil Mill Boiler Feedwater Treatment

A lot of palm oil companies now have sustainability certificates, such as ISPO (Indonesian Sustainable Palm Oil) and RSPO (Roundtable on Sustainable Palm Oil). To market palm oil and its derivatives to Europe, the European Union has implemented the EUDR, or European Union Anti-Deforestation Regulation. This regulation requires every business actor to prove that their palm oil does not originate from deforested land after the deadline of December 31, 2020. The EUDR itself will be implemented on December 30, 2026, for large and medium-sized companies. Sustainability certifications such as ISPO and RSPO are not the same as EUDR compliance, but they complement each other. This is because ISPO or RSPO serve as important tools to strengthen traceability and due diligence to comply with the EU's anti-deforestation regulations. Once certified, ISPO or RSPO simply add detailed spatial geolocation data to fully comply with the EUDR standard.

As the decarbonization trend continues to penetrate various sectors of life, various efforts aligned and relevant to decarbonization and aspirations will become a concern, even an option, and even an obligation. Sooner or later, these climate-smart efforts will become increasingly accepted and become an integral part of human life. For example, the palm oil industry is currently moving towards the use of electric vehicles in the plantation sector. The use of electric vehicles has the potential to provide added value, especially for companies that have obtained sustainability certifications such as the RSPO and ISPO. The use of electric vehicles allows palm oil companies to claim reduced fossil fuel use and reap sustainability benefits.

Another example is the use of organic fertilizers or biofertilizers. The use of biofertilizers or organic fertilizers can have several positive effects on environmental sustainability, as they can reduce the use of chemical fertilizers by up to 25%. This effort not only reduces environmental pollution and health risks but also enriches biodiversity and supports climate-smart agriculture. In an era where sustainability is a focus and a "selling point" for products (especially in Europe), this effort is very effective. This is especially true given the intense competition from other vegetable oils, such as soybean oil and sunflower seed oil.

This is also closely aligned with water treatment, particularly boiler feedwater treatment, which uses less or no chemicals. This also reduces environmental pollution and health risks. Boilers can be considered the "heart" of palm oil mills, converting water into high-pressure steam to power the production process and generate electricity for the mill and its employee housing. Like all production equipment, boilers have a lifespan. When a boiler's lifespan is exceeded, it is not only uneconomical due to high maintenance and operational costs but also dangerous. Good and well-maintained water quality will ensure the boiler's lifespan meets or even exceeds standards.

The average lifespan, which is the technical and economic life of a palm oil mill boiler, is 20 years, and by maintaining water quality, it is expected to be 20% longer, to 24 years. In addition to the technical and environmental benefits, there are also economic benefits. A palm oil mill with a capacity of 45 tons of fresh fruit bunches (FFB) per hour using electrochemical technology will achieve an estimated annual savings of over 250 million rupiah. For more detailed information, please contact us. Currently, according to data from the Indonesian Ministry of Agriculture, the number of palm oil mills in Indonesia is recorded at around 1,200 to 1,500. This is understandable, considering the increasing area of ​​oil palm plantations, currently reaching nearly 17 million hectares, thus increasing the need for palm oil mills.

Why make calculations or simulations for a palm oil mill with a capacity of 45 tons of fresh fruit bunches (FFB)/hour? This is because this capacity is the average capacity of palm oil mills in Indonesia. For example, one of the largest palm oil companies, PT Astra Agro Lestari (AALI), has 32 palm oil mills with a total capacity of 1,570 tons of fresh fruit bunches (FFB) /hour, or an average of 49 tons of FFB /hour, which is close to a capacity of 45 tons of FFB /hour. And with the number of mills in Indonesia, say 1,500 units and each mill can save 250 million rupiah/year, there will be an estimated savings of 375 billion rupiah per year from this boiler feed water treatment, in addition to technical and environmental benefits, especially to strengthen sustainability efforts to meet EUDR requirements.

Exploring the Market for Bioenergy and Biocarbon Products in the Era of Global Decarbonization

The demand to lower the earth's temperature by reducing greenhouse gas concentrations through various global agreements such as the Paris Agreement and Net Zero Emissions (NZE) 2050, followed by technical follow-up through decarbonization for various sectors and industries, continues. This is the driving force for increasing renewable fuels, especially those based on biomass or bioenergy products, which have been implemented, but are experiencing dynamics in the form of fluctuations in demand and prices. Bioenergy, with its numerous advantages and uniqueness as a renewable energy, cannot be replaced in this era of global decarbonization, even though in the near future some subsidies for biomass fuels or bioenergy will be eliminated.

This is closely related to a government's decarbonization priorities, particularly among the various emerging options. Bioenergy products can vary in quality, but all have their own market segments within specific industries. Furthermore, the sustainability of biomass sources is also a crucial aspect in the business and use of bioenergy, and is strictly enforced by standards such as GGL, FSC, SBP, RED III, and SURE. Industrial groups such as cement, iron and steel, chemicals, and even the aviation sector, which previously relied 100% on fossil fuels or energy sources, are gradually shifting to renewable energy sources.

Bioenergy products such as industrial wood pellets and industrial wood briquettes are primarily marketed in the power generation industry and as fuel for industrial boilers. Industrial wood pellets are very popular and are produced in larger quantities than industrial wood briquettes. Due to the elimination of subsidies and the implementation of sustainability certification, biomass fuel producers are required to produce better quality products using environmentally friendly and accountable raw materials. This also applies to bioenergy derived from agricultural waste, which generally lacks sustainability certification at large production capacities.

Biomass power plants operating near carbon neutrality can then be upgraded to carbon-negative operation, or atmospheric carbon dioxide removal (CDR) by adding carbon dioxide capture and storage (CCS) equipment. Biomass power plants equipped with CCS devices are popularly called BECCS (Bio-Energy Carbon Capture and Storage). It is predicted that the BECCS era will not be far off, and countries with biomass power plants can easily upgrade to BECCS. Expensive CCS equipment and low carbon credit revenue from CDR remain current obstacles. Japan, with around 300 biomass power plants, has great potential to upgrade to BECCS. And as a biomass power plant, the need for fuel will always be needed, such as wood pellets and PKS (palm kernel shells). For more details, read here.

One successful example of BECCS is the Stockholm Exergi BECCS project. BECCS illustrates how existing biomass power generation infrastructure can be leveraged to generate sustainable carbon dioxide sequestration. The Stockholm project, based on sustainably sourced biomass fuel, secured one of the world’s largest carbon sequestration deals with Microsoft, a significant contract worth SEK 500 million (~89 billion rupiah). Their model integrates carbon capture with a district heating system, maximizing energy efficiency while achieving permanent carbon dioxide sequestration.

Similarly, several other large industries, such as cement, aluminum, and chemicals, are also gradually decarbonizing. Biomass fuels, such as wood pellets and agricultural/plantation waste like palm kernel shells (PKS), are preferred in this sector. Besides their high energy content, these biomass fuels are more affordable than derivatives like torrefied biomass and charcoal/biochar. With the gradual transition or decarbonization of these industries, the demand for biomass fuels will also continue to increase.

Meanwhile, biocarbon products such as torrified biomass (biocoal) and carbonized biomass (biochar/charcoal) are starting to attract attention and are expected to reach mass production levels in the near future. Power plants typically favor biocoal due to its higher energy content, hydrophobicity, which allows it to be stored in open areas like coal, and ease of crushing (high grindability index). Meanwhile, biochar/charcoal, especially in the iron and steel industry, is highly suitable for producing low-carbon steel and even green steel. The reductant for blast furnaces, which previously used coke from coal, can be replaced by charcoal or biochar. Charcoal or biochar with high purity (fixed carbon >85%) and low impurities are required for blast furnace reductants. For more details on this, please read here and here.

Meanwhile, the use of biomass for sustainable aviation fuel or SAF (Sustainable Aviation Fuel) is also very possible. This is because currently there are three leading production processes for SAF production: HEFA (Hydro-processed Esters and Fatty Acids), FT (Fischer-Tropsch), and ATJ (Alcohol to Jet Fuel). Biomass through thermochemical processes, namely in FT (Fischer-Tropsch) and biochemical processes, namely in ATJ (Alcohol to Jet Fuel), can be used as raw material or feedstock. Meanwhile, the raw material or feedstock for the HEFA process is not solid biomass but vegetable oil, used cooking oil, animal fats, and so on. So the broad application of biomass as various important energy sources in the era of global decarbonization is a driving force for biomass production both through the forestry sector and sustainable agriculture/plantations.

 

EUDR and Is It Time for the Palm Oil Industry to Consider Biochar ?

Malaysian smallholders cultivate around 27% of the total oil palm plantations or equivalent to 1.54 million hectares, while in Indonesia it reaches 41% or equivalent to 6.72 million hectares. Malaysia chose to increase the yield or productivity of FFB as an effort to increase CPO production, namely by being fostered by large companies with a target increase of 600,000 tons/year without increasing the land area. For Malaysia, opening new plantations is something that is very difficult, even impossible, especially with the implementation of the EUDR on December 30, 2024. Consolidation between palm oil farmers is expected to increase efficiency so that it ultimately increases yield and income. The area of ​​Malaysian palm oil plantations is around 5.7 million hectares or around 1/3 of the area of ​​Indonesian palm oil plantations (currently reaching around 17 million hectares). This is also the main reason why Malaysia chose to intensify its palm oil plantations while Indonesia tends to expand palm oil land, even though both countries face two main issues, namely increasing production and climate resilience.

Biochar application is a solution to overcome the two important issues above. Related to the increasing pressure of environmental issues, climate and sustainability, even renewable energy, it seems that biochar will receive more attention. There are many aspects of land and the environment that can be improved with biochar application which ultimately is a solution to the two main issues. For small plantations, biochar application can be easier to do, but for large plantations managed by various palm oil companies, biochar application requires more complex considerations, especially because of the risk factor of the vast area of ​​palm oil plantations, but this biochar option is still attractive. The use of IoT (Internet of Things) can be used to monitor biochar performance on the land, for more details, read here.

The operational efforts of the palm oil industry to be more environmentally friendly and efficient are a driving force and a challenge in themselves. With the large profits from the palm oil industry business, of course the palm oil industry will not simply ignore demands related to the environment and sustainability, especially the EUDR. Palm oil producers, especially Indonesia and Malaysia, are faced with a standard guideline that applies to countries producing 'edible oil', namely that palm oil to be exported must come from land that has been reforested before 2020. Otherwise, the producing country will be considered a country that does not pay attention to the issue of deforestation and hinders the export of palm oil abroad. Various lobbying and negotiation efforts by Indonesia and Malaysia as the two largest palm oil producing countries in the world to the European Union to be more relaxed in implementing the EUDR include great suspicion as to why rapeseed oil is not treated the same as palm oil. The production of rapeseed oil as a raw material for biofuel in Europe is protected and ignores its environmental impact.

Indonesia as a coconut island seduction country has an experience of coconut oil commodities in the past that can also be a reference for this. The era of the glory of copra or coconut oil was around the transitional decade of the 19th century to the 20th century or more precisely between the 1870s and 1950s and its peak in the 1920s. Why are copra and coconut oil in particular currently slumping and losing out to other vegetable oils? The long history of trade competition is the answer. Several parties, especially the American Soybean Association (ASA) accused coconut oil of being an evil oil containing cholesterol and saturated fat that clogs coronary arteries. The accusation was never proven true, in fact it was proven otherwise, but it became one of the main causes of the destruction of the global copra and coconut trade. The tropical oil campaign and war took about 30 years or in the 1950s to the late 1980s in the United States and so finally the Indonesian coconut industry slumped.

Climate factors in the form of efforts to reject deforestation with its EUDR and economic factors in the form of palm oil production will be a fierce feud but sooner or later it will definitely reach a meeting point that can be accepted by both parties because they need each other. Diverting CPO products to markets that do not require environmental requirements such as the EUDR also seems to be untimely. Furthermore, in the form of addressing two important issues in the palm oil industry, namely increasing production and climate resilience and in line with the EUDR, biochar is the right solution. The question is, will this biochar be an important consideration and even find its momentum to be applied in oil palm plantations, especially for Indonesia and Malaysia? And the implementation of the EUDR as its driving force. Let’s see.

Biochar as Deforestation Solution in Palm Oil Plantations and EUDR

The development of the palm oil industry and its plantations in Indonesia is very rapid, especially in the last 10 years and currently the area of ​​Indonesian palm oil plantations is estimated to reach 17 million hectares. As the largest vegetable oil producing plant in the world and the largest palm oil plantation area in the world, of course palm oil has a strategic value in the Indonesian economy. The average speed of Indonesian palm oil plantation area is 6.5% per year or equivalent to around 1 million hectares per year for the last 5 years, while the increase in palm oil fruit production or FFB (fresh fruit bunches) is only 11% on average.

Even the largest land expansion occurred in 2017, which increased by 2.8 million hectares. From 2015 to 2019, the total area of ​​palm oil plantations increased by 3.7 million hectares. The extensification or expansion of palm oil plantations has been widely "accused" and has become the focus of the world as a result of the conversion of forest land, resulting in a lot of deforestation to be converted into palm oil plantations.

Pressure from the European Union in particular, due to these conditions, has worsened the image of Indonesian palm oil, which in turn has affected the selling price of palm oil products, both CPO and its derivative products. Improving this image is also not easy. One effective effort is to stop the extensification efforts so that forest land remains forest land and does not turn into oil palm plantations. The European Union on Deforestation-free Regulation (EUDR), which will come into effect on December 30, 2024, as an effort to prevent deforestation, is also an important consideration. The regulation requires consumers and producers along the supply chain of certain commodities to conduct due diligence and risk assessments to ensure that their products do not contribute to deforestation. The EUDR also applies a tiered inspection and penalty system based on the level of risk perceived in the country of origin.

With the extensification of oil palm land of more than 1 million per hectare each year but the increase in oil palm fruit production is only 11%, it is certainly less attractive and must be avoided, especially with the world's spotlight on the increasingly rapid deforestation. This also increasingly indicates the low productivity of palm oil plantations. In fact, by improving soil quality, palm oil fruit productivity can be increased significantly and the opening of new land for the creation of palm oil plantations can be avoided. Biomass waste in palm oil plantations and in palm oil mills can be used for biochar production as a solution to this problem.

With the increase in productivity of fresh fruit bunches (FFB) with the use of biochar, new palm oil plantations do not need to be opened again. Assuming an average increase in productivity of 20%, CPO production will also increase by 20% or equivalent to 2 million tons. This increase will be equivalent to opening new land covering an area of ​​more than 2 million hectares. Of course, it is not a small area of ​​land. With a 20% increase in production, it is very likely that national needs for CPO in particular have been met and so too for the export market. Another advantage of using biochar is as a climate solution as carbon sequestration/carbon sink. So the two main problems in the palm oil industry in the form of increasing productivity and climate change resilience can be overcome at once with the application of biochar.
