Inert waste is waste which is neither chemically nor biologically reactive and will not decompose. Examples of this are sand and concrete. This has particular relevance to landfills as inert waste typically requires lower disposal fees than biodegradable waste or hazardous waste. This type of waste coagulates in the environment and can cause serious problem, much like filling up of areas, but they are also relatively less harmful than plastics as they don't give out harmful residues after hundreds of years.
