What are the 4 difference between refuse and sewage?

Refuse refers to solid waste materials discarded by households and businesses, including food scraps, packaging, and other non-liquid waste. Sewage, on the other hand, consists of liquid waste, primarily from bathrooms and kitchens, containing water and human or industrial waste. Refuse is typically collected for disposal or recycling, while sewage is treated at wastewater treatment facilities to remove harmful substances before being released into the environment. Additionally, refuse can often be sorted and recycled, whereas sewage requires specific treatment processes to ensure safety and environmental protection.
