The refining process also generates solid waste, including spent catalysts, sludge, and other byproducts. Proper disposal or recycling of these materials is crucial to minimize land pollution and resource wastage. Many refineries are exploring sustainable waste management practices, such as reusing spent catalysts and converting waste into energy or other useful products.
