Palm Oil Extraction does not end at the final product of edible palm oil. In the process of extracting and refining palm oil, by-products (which are what remains from the palm kernel after most of the oil is removed from it) are also produced. Although most Palm Oil Business are ultimately interested in the quality of the final oil product, these by-products can also be recycled and profited from. Unfortunately, despite the overall surplus of by-products, the utilization rate of these by-products is low. With the vast experience we have in palm oil processing, we are happy to share information about the use of the by-products from Palm Oil Processing Plant.

By-products in Palm Oil Processing Plant
Palm nuts are very valuable because they can be used to create three raw products -- palm kernel oil (Palm Kernel Oil Extraction Machine), dry cakes made of mesocarp fibre, and palm kernel shells. The three main by-products from the process of extracting oil from palm kernels are the Empty Fruit Bunches (EFB), the Palm Kernel Shell (PKS), and the Mesocarp Fibre (MF). The valuable uses of these products are described below.
- Empty Fruit Bunches (EFB)
As its name suggests, these are the fibres that hold the fruits when they grow on the palm tree. These are useful biomasses formed during extraction process of palm oil. When the moisture is removed from these bunches, the EFB can serve as an efficient form of fuel with sufficient combustion temperature. These bunches can be recycled to power steam boilers to produce steam that can in turn run turbines to produce electricity. With technical and social development in our societies, as well as an increase in awareness in environmental sustainability, EFBs have increasingly been used as a valuable source of renewable energy.

- Palm Kernel Shell (PKS)
After the seed is removed from its kernel for oil extraction, the remaining fractions of shell that are removed after they are crushed become a useful by-product known as the palm kernel shells. These shells will either be large, fibrous and bulky, or small and dust-like. All of these are mixed together to create a good quality biomass fuel that is easily handled and stored due to its low moisture content. These fibres can usually be pressed to form solid fuels to power steam boilers, just like the EFB, to generate electricity. With these sources of fuel (from the EFB and the PKS), palm oil production mills are often self-sufficient and able to produce the energy they require to power the machines using only these by-product biomass fuels from their own production chain. These fuels are also cleaner and preferred over coal because it emits less dark smoke that exacerbate the issue of global climate change.

- Mesocarp Fibres (MF)
After the palm oil fruits are pressed, the remaining dry "cake" that is formed is made up of mesocarp fibres. These "cakes" have several uses ranging from being turned into soil fertiliser, being used to make fibre boards and blackboards, to making fatty-acid based animal feed.

- Palm Oil
Palm oil is often the main product that producers are aiming to extract and sell. However, for businesses looking for diversification, the final product of palm oil can also be further used as a raw material to manufacture soaps.
