*4.1.2 Industrial waste composting*

Industrial waste composting or commercial composting is a large-scale recycling of organic, biodegradable waste materials in order to produce natural soil enhancers or fertilizers used in farming [24]. The composts formed in this waste disposal method (the process is shown in **Figure 8**) are then sold to agricultural centers, farms, or plant nurseries. Typically composting industrial wastes is achieved by first, collecting waste from food processing industries, grocery stores, large restaurants, and other commercial facilities and processing them at a compost processing plant (compost machine) where foreign materials are initially removed and the food wastes mixed with sludge [24].
