This version of Warm, released in August 2010, incorporates several updates and enhancements from the previous Warm Version 10. In This Internet page newest version of Warm, EPA modified the interface to display ends in metric tons of carbon dioxide equal (MTCO2E) as the default unit for GHG emissions, however results are nonetheless available in units of metric tons of carbon equivalent (MTCE). For info on the key adjustments to the up to date Aluminum Cans and new Aluminum Ingot materials GHG emission and power Factors for Warm version 12, please see the Aluminum FAQ doc. Additionally, new emission factors were developed for polylactide (PLA) and aluminum ingot. State electricity grid emission factors had been up to date based mostly on the 2015 update to the eGRID database. U.S. Department of Energy, Energy Information Agency's 2015 Monthly Energy Review. U.S. Department of Energy (DOE) Energy Information Administration's (EIA's) 2017 Monthly Energy Review whereas state electricity grid emission factors have been updated based mostly on the 2018 replace to the eGRID database. Warm Version 14 (xls) was released in March 2016 and incorporates the new material administration pathway, anaerobic digestion, and common updates to various components within the mannequin utilizing present information sources. This version was launched in November 2001 and mirrored a number of enhancements made to the earlier version of Warm (version 2). For contributors in the U.S.

Waste Reduction Model (Warm) Version 12 (zip) (282.26 KB) , released in February 2012, contains several updates and enhancements from the earlier Warm Version 11. On this newest version of Warm, the interface shows results in metric tons of carbon dioxide equivalent (MTCO2E) because the default unit for GHG emissions, however outcomes are still out there in items of metric tons of carbon equivalent (MTCE). Greenhouse Gas (GHG) Emissions and Sinks: 1990-2014. The non-biogenic carbon content material of combined municipal strong waste (MSW) was updated utilizing annual waste disposal knowledge from EPA's Advancing Sustainable Materials Management: Facts and Figures Fact Sheet. Greenhouse Gas (GHG) Emissions and Sinks: 1990-2016. The non-biogenic carbon content of mixed municipal solid waste (MSW) was updated utilizing annual waste disposal information from EPA's Advancing Sustainable Materials Management: Facts and Figures Fact Sheet. Greenhouse Gas Emissions and Sinks: 1990-2008. The non-biogenic carbon content material of combined MSW was up to date utilizing annual waste disposal information from EPA’s "Municipal Solid Waste in the United States, 2008 Facts and Figures" and BioCycle’s "State of Garbage in America" 2008 report. Statistics on the carbon content of fuels, landfill methane technology distribution (by sort of landfill), and landfill fuel recovery and flaring rates have been included from EPA’s Inventory of U.S.

The newest 2012 statistics on the carbon content of fuels, landfill methane technology distribution (by kind of landfill), and landfill fuel restoration and flaring charges have been included from EPA's Inventory of U.S. Various facets of the U.S. The latest 2014 statistics on the carbon content of fuels, landfill methane era distribution (by type of landfill), and landfill gas recovery and flaring rates have been included from EPA's Inventory of U.S. The most recent 2010 statistics on the carbon content of fuels, landfill methane era distribution (by kind of landfill), and landfill gas restoration and flaring charges have been included from EPA's Inventory of U.S. Also added were updates on the carbon content material of fuels, landfill methane generation distribution (by type of landfill), landfill fuel recovery and flaring rates, and waste generation and restoration rates. Additionally, the Excel version of Warm now incorporates area-specific electricity grid components to extra precisely model emissions associated with averted technology of electricity because of landfill gas restoration in the landfilling pathway and waste-to-vitality within the combustion pathway. Component-specific decay charges had been added for all organic materials to extra accurately mannequin the rate at which every material decays inside a landfill beneath given landfill moisture situations.

The up to date analysis from Dr. Morton Barlaz on component-particular decay charges and landfill fuel collection efficiency, upon which these new factors are primarily based, is described further within the memorandum to EPA entitled "WARM part-specific decay fee strategies," obtainable among the Warm background paperwork. EPA corrected errors that had applied incorrect landfilling emission components when users chosen certain landfill management options or situations in the device. As well as, the Excel version of Warm now permits customers the choice of deciding on and reviewing results based mostly on California regulatory gasoline collection scenario as one of 4 landfill gas collection situations. The part-specific decay charges modeled in Warm are additionally obtainable as a user-defined input within the Excel version of Warm and are based on choosing one of 4 landfill climate/moisture characteristics: dry, average, wet, or bioreactor. New emission components had been added for 4 plastics, linear low-density polyethylene (LLDPE), polypropylene (PP), polystyrene (PS) and polyvinyl Chloride (PVC).
