Waste by country Waste by country Waste, unwanted or unusable material, varies in type and quantity in the different countries around the world. Developed countries produce more waste per capita because they have higher levels of consumption. There are higher proportions of plastics, metals, and paper in the municipal solid waste stream and there are higher labour costs. As countries continue developing, there is a reduction in biological solid waste and ash. Per capita waste generation in OECD countries has increased by 14% since 1990, and 35% since 1980. Waste generation generally grows at a rate slightly lower than GDP in these countries.
