I have to agree with you here. Decomposing organics in a landfill produces methane which is worse than CO2 for trapping heat in the atmosphere. Lots of places in Europe use incineration as a method of garbage disposal and pipe the waste heat, left over from making electricity, to neighboring buildings for home heating.But a lot of the carbon in rubbish is from plants (carbon neutral) and that the energy would have only been produced from fossil fuels anyway. I'm not proposing this as an alternative to greener technologies such as wind, hydroelectric and solar but as a replacement for coal, oil and gas fired power stations.
