Palm Fruit Bundle Regeneration: Empty Fruit Bundles as Organic Fertilizer for Soil Improvement

Empty palm fruit bunches are the fibrous fruit clusters remaining after the palm fruits have been steamed and threshed during the palm oil extraction process. Approximately 0.2 to 0.25 tons of empty fruit bunches are produced for every ton of palm oil produced. These materials have a moisture content of about 60% to 70%, a cellulose content as high as 40% to 50%, a hemicellulose content of 20% to 25%, and a lignin content of 15% to 20%, with a carbon-to-nitrogen ratio as high as 70:1 to 100:1, making them extremely slow to decompose naturally. If left untreated, accumulation or incineration will cause serious environmental problems. However, through mechanical processing and microbial fermentation, empty fruit bunches can be transformed into high-quality organic soil conditioners.
