Are there any environmental concerns as a result of cremation?
Wikipedia states: There is a growing body of research that indicates cremation has a significant impact on the environment: The major emissions from crematories are: nitrogen oxides, carbon monoxide, sulfur dioxide, particulate matter, mercury, hydrogen fluoride (HF), hydrogen chloride (HCl), NMVOCs [non-methane volatile organic compounds], and other heavy metals, in addition to Persistent Organic Pollutants (POP). According to the United Nations Environment Programme report on POP Emission Inventory Guidebook, emissions from crematoria, although comparatively small on an international scale, are still statistically significant. The POP inventory indicates that crematoria contribute 0.2% of the global emission of dioxins and furans.
