In Scandinavia, the garbage is sorted into several categories at the source i.e. by the people and then thrown into the garbage collectors nearby their residences. Thus biogas and leachate are produced from the putrescible or biodegradable waste, they also produce biofuel or ethanol which is used especially in public transport within the cities i.e. metro
Metals, plastics, glass are recycled while dry waste is burnt to produce electricity and district heating i.e. heating for the whole community by warming up water in a boiler and thus recirculating through a residential, commercial and office areas thus they receive hot water the year round and used for shower, radiators for heating, washing machines, dish machines, or just manual washing of dishes etc.. though the warm water is not recommended for drinking, used cold water instead for drinking.
