Humanity knows three ways to deal with waste: incineration, burial (landfills) and recycling. All the methods, except reuse recycle, destroy nature are dangerous for ecology human health exactly. Each year Russians produce about 50 million tons solid waste, most part of which goes landfills. National green projects aimed create visible eco-friendly system by awarding greenwashing grants: landfi...
This study was conducted to investigate thermal aspects of municipal solid waste landfills as a function of operational conditions and climatic region. Spatial and temporal distributions of waste temperatures were determined at four landfills located in North America �Michigan, New Mexico, Alaska, and British Columbia�. Temperatures of wastes at shallow depths �extending to 6 to 8 m depth� and ...
Hydrogen sulfide (H2S), a major odorous component emitted from construction and demolition debris landfills, has received increasing attention. Although cover materials such as soil and compost are recommended to be used routinely to control an odor problem from the landfills, the problem still remains. Autotrophic denitrification may have environmental applications including treatment of water...
Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extr...
this study at first level focused on definitions and descriptions of some landfills and landfills sites all around the world and survey on how important they are for regional governments and responsible in duty as a very important responsibility for locals and their health. at the second level we had a look on heavy metals concentration which are by many definitions as follows: lead, nickel,...

There is considerable interest today in the so-called “biocell” approach toward municipal solid waste (MSW) landfilling in which leachate is introduced back into the landfill. This approach reduces the cost of leachate management and is said to reduce/eliminate the potential for long term landfill gas production and groundwater pollution. However, a critical review of the typical approach being...
