Mutton fat is less common than beef or pork fat and usually more expensive due to limited supply. However, in regions with high sheep farming, it becomes a readily available byproduct of meat processing. It is cheaper than virgin plant oils like soybean or rapeseed but may require more pretreatment. The GlobeCore USB plant’s adaptability to various feedstocks makes it well-suited for localized production where mutton fat is abundant, helping convert regional waste into a valuable energy resource.
