Therefore, a few assumptions were made to determine future adoption: biogas represents around 20 percent of total electricity generation from bioenergy worldwide, and biogas from landfills covered within this solution represents 30 percent of total biogas. Ideally, those wastes would be recycled, composted, or digested. The total addressable market for landfill methane capture is based on projected global electricity generation from 2020-2050. Landfill methane can be tapped, captured, and used as a fairly clean energy source for generating electricity or heat, rather than leaking into the air or being dispersed as waste. Our staff and fellows are actively involved in climate solutions outreach, as shown here at the Keeling Curve Prize event in Colorado, 2019.

Inputs were determined from the variable meta-analysis done, and account for the extra costs of flaring systems. [3] To learn more about Project Drawdown’s two adoption scenarios, click the Scenarios link below. Over the course of a century, methane has 34 times the greenhouse effect of carbon dioxide. Current adoption[2] is considered to be 33.1 terawatt-hours, or 0.13 percent of total electricity generated worldwide. Sustainable Intensification for Smallholders. Total adoption estimates vary widely between different future adoption prognostications, due to the fact that different sources place a different value on biomass and waste for energy adoption. EPA Regulations The EPA’s Landfill Methane Outreach Program is entirely voluntary, but the EPA does have the authority to regulate landfills and LFG through the Resource Conservation and Recovery Act (RCRA) and the Clean Air Act. The Scenario 1 adoption of landfill methane would require an estimated US$34.7 billion in cumulative first costs. Through the process of integrating landfill methane capture with other solutions, the total addressable market for electricity generation technologies was adjusted to account for reduced demand resulting from the growth of more energy-efficient technologies,[5] as well as increased electrification from other solutions like electric cars and high-speed rail. Therefore, as landfills move globally from open dumps or basic landfills to engineered sanitary landfills, the percentage of landfills which use landfill methane capture can and should be expected to increase. The climate benefit is twofold: prevent landfill emissions and displace coal, oil, or natural gas that might otherwise be used. Dispersed, perforated tubes are sent down into a landfill’s depths to collect gas, which is piped to a central collection area where it can be vented or flared. For landfill methane, the two scenarios developed are: Landfill methane emission rates are estimated using the first-order decay method recommended by the Intergovernmental Panel on Climate Change (IPCC), in order to estimate both total emissions reductions for landfill gas-to-electricity generation and an increase in landfill gas flaring. This solution sits at the bottom of the waste hierarchy. Two total addressable markets were developed for this sector solutions, supported on lower and higher climate emissions mitigation targets linked to different levels of electricity demand and renewable energy sources integration. Combusting landfill methane for electricity generation can result in emissions reductions equivalent to 2.2 gigatons greenhouse gases emissions over a thirty-year period. The Landfill Methane Capture Strategy includes three core components: Install new methane control systems at landfills currently without control systems. And according to the EPA, municipal solid waste landfills account for 14% of all human-related methane emissions in the U.S. each year—the third largest source behind the gas and petroleum industry, and agriculture. Sustainable Intensification for Smallholders. Maximize landfill methane capture efficiencies by optimizing landfill design, operation, and closure/post closure practices. Due to integration and waste feedstock availability, the Scenario 2 depicts negative impacts on greenhouse gas emission reductions over 2020-2050 of -1.6 gigatons of carbon dioxide-equivalent when compared to a Reference scenario, since the adoption and consequent share of the solution on the total addressable market decrease significantly through the period of analysis. What cannot, or should not, be combusted in waste-to-energy facilities will reach landfills as a last resort. All rights reserved. The sources used do not clearly depict landfill methane and biogas technologies for electricity generation adoption pathways; instead, their results combine biomass and waste for electricity generation. These solutions will not be adopted globally overnight, so we assume landfill methane capture will continue to play a role. An average capacity factor of 80 percent was used for the solution, compared to 55 percent for conventional technologies. Landfills are a top source of methane emissions, releasing 12 percent of the world’s total. Landfill waste will decline as diets change, waste is reduced, and recycling and composting grow. Michigan Attorney General Dana Nessel filed a lawsuit against the operator of the Arbor Hills Landfill in Salem Township for failing to comply with state and federal regulations. At the same time, methane emissions from landfills represent a lost opportunity to capture and use a significant energy resource.When MSW is first deposited in a landfill, it undergoes an aerobic (with oxygen) decomposition stage when little methane is generated. The climate benefit is twofold: prevent landfill emissions and displace coal, oil, or natural gas that might otherwise be used.
