Biochar for Palm Oil Nurseries

There are about 250 producers of palm oil seedlings in Indonesia, and with an area of the palm oil plantation reaching around 15 million hectares, these seedling producers are actually not many either. More specifically, Sumatra island has the largest area of palm oil plantations in Indonesia, making it the main economic activity in the area, because 70 percent of palm oil land in Indonesia is in Sumatra. With a cropping pattern, for example, 125 trees per hectare, 125,000 trees are needed for every 1,000 hectares or 1 million hectares for 125 million trees, while 15 million hectares means more than 1.8 trillion palm oil trees with current crude palm oil (CPO) production reaching more than 40 million tons per year. A very large number, of course. But not only the quantity factor, the seed quality factor is prioritized so that it has optimal productivity. Of course, the need for seeds does not necessarily mean millions or trillions of trees at the same time, depending on needs such as new plantings from new plantations (extensification) - which is currently being carried out in Indonesia or rejuvenation of palm oil plantations (replanting) which is carried out periodically.

One of the good palm oil seeds is determined by the quality of the growing media. The growing medium for palm oil seedlings generally consists of topsoil mixed with sand or organic matter to obtain a fertile medium. Compost or manure is often used to improve soil fertility by supplying nutrients to plants. With a tropical climate with high rainfall, nutrients can be easily washed away, besides that, low soil pH is also a separate obstacle for the growth of these seeds. By using biochar, nutrients or plant nutrients become more available, humidity and microbial activity will increase. This makes the quality of the planting medium high quality, so that the resulting palm oil seed products in the form of roots, plant height, number of leaves and plant weight are the parameters observed with the use of biochar which are also getting better.

Compared to using cocopeat, biochar has a number of advantages. Both cocopeat and biochar have uses in agriculture, but there are a number of differences between the two. Cocopeat has uses mainly as a planting medium because of its water holding capacity, while biochar besides having the ability to hold water like cocopeat also raises soil pH, holds or makes nutrients more available (nutrient retention), and also becomes a soil microbial colony so that Organic materials become quickly decomposed and absorbed by plants. Cocopeat will also decompose in a short time like compost, while biochar can survive and not decompose for hundreds of years. Under these conditions, biochar is also used to store CO2 (carbon sequestration) and obtain carbon credits with the carbon sink mechanism.

The palm oil nursery is the starting point that most determines the further growth of the palm oil in the field. The success of growing palm oil plants in the field is largely determined by the quality of the seeds planted. Seedlings that grow well in nurseries have high adaptability in the field. In practice, it has been proven by a number of studies that the use of biochar has a positive effect on palm seed products. The use of biochar in the range of 40% has become the best composition for the planting medium for the palm oil seeds. This should encourage producers of palm oil seeds to use biochar.

Cocopeat and Biochar

Both cocopeat and biochar have uses in agriculture, but there are a number of differences between the two. Cocopeat is mainly used as a planting medium because of its water holding capacity, while biochar in addition to having the ability to hold water like cocopeat also raises soil pH, holds or makes nutrients more available (nutrient retention), and also becomes a colony of soil microbes so that organic matter becomes rapidly decomposed and absorbed by plants. Cocopeat will also decompose in a not too long time like compost while biochar can exist and not decompose for hundreds of years. Under these conditions, biochar is also used to store CO2 (carbon sequenstration) and obtain carbon credits with a carbon sink mechanism.

 

Choose Biochar or Cocopeat?
With these advantages, choosing biochar would be better. Moreover, the cocopeat can also be used for biochar production. The carbon removal program to reduce the concentration of CO2 in the atmosphere is also in line with the application of the biochar. Increasing global awareness of climate change and global warming makes carbon removal programs that also provide economic benefits from carbon credits likely to continue to increase in the near future. This cannot be done with cocopeat.

Converting cocopeat into biochar is also not difficult, even with a variety of simple (low tech) equipments it can be done. But for a large capacity so that the carbon credit program can run, it requires modern pyrolysis equipment with a large capacity. With this equipment, in addition to biochar production, there is also a number of excess energy that can be used for various purposes, one of which is drying cocopeat before it becomes raw material for biochar with such pyrolysis equipment.

Integration of Pyrolysis with Cocopeat and Cocofiber Industries

The high demand for cocofiber and cocopeat in the world which reaches thousands of containers per year should be a golden opportunity and a driving force for the Indonesian coconut industry. There are a number of potential advantages of Indonesia which should be at the forefront of capturing and exploiting these opportunities. These advantages include, from 196 countries in the world, only 8 countries control 90% of the world's coconut demand, Indonesia as the owner of the largest coconut plantation in the world, which is around 3.8 million hectares with a production of more than 15 billion coconuts fruit every year, and strategic geographical position. This is also the reason why the ICC (International Coconut Community) or an international organization concerned that the members of which are coconut producing countries is headquartered in Jakarta, Indonesia. The island of Sumatra is the center of the largest coconut plantation in Indonesia, especially Indragiri Hilir regency in Riau province, followed by the islands of Sulawesi, Java, Maluku and Papua, Nusa Tenggara and Bali, and Kalimantan. The current condition, although with a number of advantages above and the quality of Indonesian coconut coir is high and the price of this coir is cheap, it turns out that Indonesia still supplies less than 5% of the world's cocofiber and cocopeat needs.

To seize these opportunities, of course, one cannot only rely on the potentials, but also on effective and efficient production technology. One of the main obstacles in increasing cocofiber and cocopeat production capacity is the drying aspect. The production of cocofiber and cocopeat can be boosted in such a way if the efficient drying aspect can be carried out. And for drying, heat energy is absolutely necessary. This heat energy can be obtained cheaply from the excess energy of the pyrolysis process. In addition to producing the main product in the form of biochar, excess energy from the pyrolysis process can be relied on as an energy source or heat source for the coconut coir processing industry. A certain type of dryer according to the characteristics of the material being dried must also be used. With modern dryers such as belt dryers, tray dryers and drum dryers, in addition to the high drying capacity, the product quality will also be standard and stable.

Meanwhile, for the pyrolysis process, raw materials are needed in the form of biomass wastes that are widely available in that location, even the biomass waste can vary according to its availability which sometimes depends on the season. In certain cases, it is also possible for pyrolysis to be integrated with an integrated coconut industry, so that coconut shell becomes the raw material. Meanwhile, if the location of the coconut plantation is not far from the palm oil plantation, biomass wastes from the plantation or palm oil mill can be used for the pyrolysis. Even like the palm oil trunk, if it is not used and only left to rot in the plantation, it invites insects that disturb the coconut plantation. For more details, you can read it here. The integration of the pyrolysis industry and coconut coir processing in addition to reducing environmental pollution due to biomass waste is also a solution for the coconut coir industry. The relationship between the two industries must be mutually beneficial, namely the pyrolysis industry can sell its excess energy at a competitive price and the coconut coir industry can increase its production.
