Palm Kernel Expeller (PKE) is a high-quality byproduct derived from the mechanical extraction of oil from palm kernels, the seeds of the oil palm fruit. Rich in fiber and protein, PKE is widely utilized in animal feed, particularly for ruminants such as cattle and goats, due to its nutritional benefits. Additionally, it serves as an organic fertilizer, enhancing soil quality, and is increasingly being used in the production of biofuels because of its energy-rich properties. Sourced from Indonesia's robust palm oil industry, PKE is a sustainable and eco-friendly option that aligns with global efforts to promote circular economy practices, making it an attractive choice for both agricultural and industrial applications.
