Final answer:
Decay, filtration, and incineration are processes used to process and recycle waste.
Step-by-step explanation:
Decay, filtration, and incineration are all processes whereby waste is processed and recycled. These processes are commonly used in waste management systems to reduce the amount of waste that goes to landfills and to minimize the negative impact of waste on the environment. Decay refers to the natural breakdown of organic matter by microorganisms, while filtration involves passing waste through filters to remove contaminants. Incineration is the burning of waste at high temperatures to convert it into ash and gas.
