Biochar for Sustainable Coconut Productivity

Coconut fiber accounts for 30%, or about a third, of the weight of a coconut. This material is generally left in plantations and remains largely unused, potentially polluting the environment. With Indonesian coconut production reaching approximately 2.9 million tons per year, or 15.13 million coconuts per year, the potential for coconut fiber production is enormous, amounting to approximately 1 million wet tons (average moisture content of 60%) or 500,000 dry tons (10%) of moisture.

The volume of coconut husk is largely unaffected by the government's recent policy of exporting whole coconuts, particularly to China, as shown in this video. Many coconut-based industries are struggling to secure raw material supplies, even leading to factory closures. Industries such as dessicated coconut, coconut milk, coconut shell charcoal and charcoal briquettes, and activated carbon are severely impacted by this policy. Selling processed or industrialized coconut products would clearly add greater value and create jobs. Developed countries also export finished or semi-finished goods, not raw materials.

The industrialization of coconut-based products is crucial. Like palm oil, coconut processing products are primarily used for food products. Utilization for energy or biofuel is also very possible, such as for sustainable aviation fuel or SAF (Sustainable Aviation Fuel). Even for palm oil, the use of biofuel is in the form of a mandatory blend of palm oil from CPO (crude palm oil) in biodiesel 40% this year and is being reviewed to be 50% (B50) by 2026, as well as palm oil from PKO (palm kernel oil) for a 3% blend for sustainable aviation fuel or SAF in 2026. The main content of coconut oil is lauric acid, the same as palm kernel oil or PKO. Lauric acid consisting of 12 carbon atoms (C) or MCFA (medium chain fatty acids) is very suitable for the use of sustainable aviation fuel or SAF must have a carbon atom bond or C bond in the range of C10-C15, for more details read here.

 

Coconut productivity continues to decline due to inadequate or slow replanting programs. A similar situation is also experienced by oil palms (for more details, read here), and this presents a unique obstacle. The area of ​​coconut plantations that needs replanting also reaches tens or even hundreds of thousands of hectares. For example, in Riau Province, the target is 43,388 hectares of coconut plantations to be rejuvenated by 2025. In addition to increasing coconut productivity through the use of superior seeds, intensification is also necessary. High coconut productivity and high selling prices are driving this replanting.

Utilizing or producing biochar from coconut fiber is a solution to increase sustainable coconut productivity. Biochar can also significantly support organic coconut plantations. Although coconut trees are generally not fertilized adequately or even not at all, they still bear fruit. Biochar increases fertilizer use efficiency because biochar acts as a slow-release fertilizer agent. Regarding fertilization, coconuts differ significantly from oil palms, which require fertilization for fruiting and are highly dependent on chemical fertilizers. In fact, fertilization is the highest cost component in oil palm plantations. Organic coconut products produce desirable derivative products with high selling prices.

The potential revenue from carbon credits is also very attractive. To obtain carbon credits, or BCR (Biochar Carbon Removal), the biochar application, including the production process, must be verified by a carbon standards agency. Carbon standards agencies such as Puro Earth, Verra, and CSI have developed methodologies that biochar producers must follow to obtain these credits.
