In most countries in the world, organic materials and paper are the main contributors to municipal waste. In developing countries, large cities generate most of the municipal waste. Data are rarely available for rural areas, but factors like the type of energy source used for cooking and heating and seasonal differences play a part in the composition of waste (for example in rural communities in Mongolia there is a large difference between the volume of wood ash produced in summer and winter).
