The value of oil palm waste as organic fertilizer
2020-05-20
Oil palm is a very cold resistant tree, which is a crop with good economic value and widely planted in some areas. A large amount of waste remains after oil palm is used, which can still be recycled again and processed into fertilizer products through the organic fertilizer production line.
Palm has unique biological characteristics:
1. Long fruiting period and high oil content. The results began in the third year after the oil palm was planted, and it entered the prosperous production period in 6-7 years, with an economic life of 20-25 years. The oil content of oil palm fruit is more than 50%.
2. Strong adaptability, easy to manage. Oil palm can grow in arid and barren areas, with few diseases and pests, high and stable canopy coverage.
3. Low production cost, extensive management, convenient operation and long term of return on investment.

Palm waste made organic fertilizer
As an example, oil palm is a cash crop in many countries, especially in Southeast Asia. The harvest of oil palm resulted in a large amount of biomass and waste. Biomass and waste are produced in a variety of forms, including harvested palm trunks, palm leaves from daily pruning, empty bundles, shells, fibers, and effluents from the processing of the entire fruit bundle.
Although factory waste, filter cake (or factory sludge) and washing waste have been converted into useful by-products, such as fertilizer, fuel, animal feed and biogas, most of the biomass and waste produced by the harvested oil palm has not been treated in a satisfactory way. For example, the most common way to deal with biomass and waste is combustion. The combustion of biomass and waste materials has resulted in a lot of pollution and is considered unsatisfactory. Now many countries (including Indonesia and Malaysia) prohibit the burning of biomass and waste from oil palm.
In the treatment of oil palm waste, it is similar to the biomass and waste of jujube, which can be decomposed or decomposed in a long period of time.
Other ways of treating leaves include simply piling up around the harvest site, where biomass or waste can decay or decompose over a longer period of time. However, this method is generally unsatisfactory when the rate of accumulation of biomass and waste materials is greater than the rate of decay. Therefore, NPK fertilizer granulator manufacturers recommend to compost palm waste into organic fertilizer products.
The compost fermentation of palm waste can not only solve the waste, but also realize the economic benefits of two times recovery. Fertilizer granulator can make the rotten waste into organic fertilizer products suitable for different crops to achieve ecological balance.
