Palm trees and their processing industries produce a lot of waste, of various types, such as old leaves, dead leaves, discarded palm trunks, empty branches of palm fruit bunches, and in addition, in the processing of palm oil, a lot of waste is also produced, such as palm shells and palm fiber after palm pulp is squeezed
In countries with abundant palm plantations, these palm wastes are rare renewable resources after being dried by palm waste dryers
These palm wastes generally have a high water content. After being dried by the
palm waste drying plant, they can be made into organic fertilizers. The potassium content of palm leaves after drying and crushing can reach 3-5%, which can be used as slow-release fertilizers. After the shells are carbonized, they can be made into biochar fertilizers and cultivation substrates. The water retention performance of palm fiber replacing peat soil reaches 20%, which is particularly suitable for blue river and edible fungus cultivation
In addition, it can also contribute to industrial raw materials. After palm waste is dried by the dryer, the environmentally friendly packaging materials produced can be decomposed in 180 days, and the decomposition rate reaches 80%. Nutshell activated carbon can help with wastewater treatment, and the efficiency of heavy metal adsorption can reach 85%. Currently, palm waste needs a successful business case to benefit mankind. Malaysia can process 500,000 tons of palm waste every year, and the power generation is enough for 100,000 households. Colombian agricultural cooperatives use palm leaf compost as a special fertilizer for coffee plantations, which can increase by 8-12%. From the perspective of economic benefits, investing in a small palm waste drying plant (5 tons/day) can pay back the investment in 2-3 years!
