Cooling Agents: An Analysis of Climate Change Mitigatin by the Informal Recycling Sector in India

Rising levels of gases in the Earth’s atmosphere are affecting the stability of the climate. Warming of the climate system is now unequivocal, evidenced by increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea levels. Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the increase in anthropogenic (human-induced) concentrations of six greenhouse gases (GHGs).

Anaerobic Digestion of Food Waste

Food waste is the single largest category of municipal solid waste (MSW) in California at 5.9 million tons or 16% of total MSW as of 1999 (CIWMB, 1999). Diverting a portion of food waste from landfills can provide a significant contribution toward achieving EPA, state, and local mandated solid waste diversion goals. In addition, diverting food waste from landfills prevents uncontrolled emissions of its breakdown products, including methane—a potent greenhouse gas.

Validation Tests for PCDD/PCDF Long-Term Monitoring Systems: Short Comings of Short Term Sampling and Other Lessons Learned

Over the past 10 years it was discovered that especially during start-up periods of (even state of art) incinerators the dioxin emissions in the flue-gas can increase compared to normal operation up to factors of 1000 in raw gas and after bagfilter. Another study quantified that around 40 % of the yearly dioxin emissions of a plant are produced and emitted during the 4 start-ups in one year.
