04/22/2013 <br /> Emissions from waste result from organic materials decomposing in the anaerobic environment <br /> of a landfill that produces methane—a GHG 21 times more potent than carbon dioxide. Organic <br /> materials (e.g., paper, plant debris, food waste, and so forth) generate methane within the <br /> anaerobic environment of a landfill while non-organic materials do not (e.g., metal, glass, and so <br /> on).

Materials that do not release GHGs as they decompose <br /> are included in the "All Other Waste" category. <br /> Table 3: Assumed Waste Composition9 <br /> Waste Type Waste Share <br /> Paper Products 21.0 % <br /> Food Waste 14.6% <br /> Plant Debris 6.9% <br /> Wood/Textiles 21.8% <br /> All Other Waste 35.7% <br /> Total 100 % <br /> 2.4 Wastewater Treatment <br /> Emissions from the wastewater treatment plant located in Redwood City are approximately <br /> 1,523 MTCO2e/year, which is less than one-half of one percent of total emissions in 2005. There <br /> are three types of GHG emissions included: 1) stationary methane from incomplete combustion <br /> of digester gas, 2) process emissions from the wastewater treatment without <br /> nitrification/denitrification, and 3) process emissions from effluent discharge to rivers and <br /> estuaries. Emissions were calculated using LGOP's methodology for Wastewater Treatment <br /> Facilities. <br /> 2.5 Agriculture <br /> Agriculture emissions totaled 594 MTCOZe/year, which is 0.1 percent of total emissions in 2005, <br /> and are based on the total amount of agricultural land in Redwood City. Agriculture emissions <br /> are due to four categories of activities: Agricultural equipment, animal waste, soil management, <br /> and biomass burning. <br /> 2.6 Municipal Operations <br /> In 2005, Redwood City's municipal operations generated 8,059 MTCO2e, accounting for slightly <br /> over 1 percent of the city's total emissions.
