In the US, almost everything sent there. Household waste should be separated into categorized bins; Compost, Glass, Aluminum, Steel, Burnable waste, Non-burnable waste, and E-waste. Unfortunately there is no incentive for consumers to do this and this results in a particularly putrid communal dumpster situation for a first world country. Even if household consumers separate their waste the garbage collection would throw it all in the landfill anyway because recycling in the US doesn't exsist. It was a scam to decrease the guilt in consumers and increase single use plastic consumption. The only thing that should go to landfills is ash, and in some cases non-burnable waste.
