Composting Council has explained the value of composting by scientifically analyzing why it is important for organics to stay out of landfills. First and foremost, landfills are harmful to the environment due to their tendency to produce methane gas. According to one study, methane gas is “25 times more harmful as a greenhouse gas than carbon dioxide” (“Keep Organics Out”). Though newer landfills have built systems to collect methane gas, older landfills still lack the technology necessary to capture these emissions. Even landfills that are equipped for methane capture fail to solve the problem entirely, because “25% of the methane generated in a landfill with gas collection will escape” (“Keep Organics Out”). On the other hand, composting is an environmentally conscious alternative to landfills. Composting does not produce methane in the same way as landfills, because organic waste only generates methane gas when placed in an anaerobic environment. Thus, the same piece of organic waste which generates a significant amount of methane in a landfill can generate a virtually insignificant amount of methane when placed in a compost pile. In fact, the only greenhouse gas emissions generated in the composting process are a result of managing operations and facilities. In addition, compost is beneficial because it saves valuable space. As a versatile substance for landscaping, erosion, and stormwater management, compost is not destined to sit in a pile for eternity. Thus, it can save valuable space in city and urban areas. Composting’s versatility is likewise important for the process of nutrient cycling. Less than one third of leaf and branch materials placed in a landfill actually biodegrades. The compost made from this same material can produce biological energy to fuel nutrient cycling (“Keep Organics Out”). In all, composting’s ability to limit methane emissions, liberate miles of land, and fuel important biological processes illustrates its advantages to
