Current Processing Status of Empty Fruit Bunches in Malaysian Palm Oil Mills: Drying Fiber to Produce Fuel

Malaysia, as one of the major producers of oil palm trees, boasts vast acres of oil palm plantations that occupy a significant share of global oil palm distribution. This fertile land not only supplies abundant raw materials for the palm oil industry but also generates substantial by-products—empty fruit bunches (EFB) from palm fruits. These EFBs, once considered waste, are now being transformed into valuable green energy under the modern concepts of environmental protection and resource recycling.

Exploration of Drying and Incineration Process

With the acceleration of urbanization and the continuous development of industrial production, the generation of sludge has been increasing steadily. Sludge contains a large amount of organic matter, heavy metals, and other harmful components, which pose a potential threat to the environment if not properly treated. Therefore, sludge treatment and disposal have become crucial tasks in urban construction and environmental protection. Currently, sludge drying and incineration, as an effective sludge treatment method, have been widely applied both domestically and internationally.

Approaches to Sludge Disposal and Management

Sludge is a byproduct produced during the sewage treatment process of a sewage treatment plant. It is an aggregate formed by suspended matter, microorganisms, organic matter adsorbed by microorganisms, and products of microbial metabolic activities in sewage. It may also contain a large amount of heavy metals, pathogens, and viruses.
