Due to its high content of methane, landfill gas can be regarded on the one hand as a useful alternative source of energy, when collected and utilized, whilst on the other hand, when released unused and untreated into the atmosphere, it causes considerable harm to the environment, contributing substantially to …

This article discusses the trace gases likely to be present in the landfill gas from a typical United Kingdom Landfill, and provides some pointers to sources of further information available on this subject.

Let us begin with a fact. There is abundant evidence from geology, archaeology, history and meteorology, that climate changes from time to time and there is abundant evidence that changes can be rapid and extreme. For example about 100,000 years ago the climate of British Isles, like the rest of …
