The recent COP29 conference has spotlighted the critical issue of methane emissions in waste management, highlighting the urgent need for effective strategies to address this challenge. Methane is primarily generated through anaerobic decomposition processes, where organic waste—such as food waste, agricultural residues, and sewage sludge—undergoes microbial breakdown in oxygen-deprived environments. Landfills, in particular, are significant sources of methane emissions, as organic waste buried underground continues to release methane over time in the absence of oxygen.
As a flammable and explosive gas, when the methane concentration reaches 5%-15%, it may cause an explosion when encountering a fire source, posing a serious safety threat to waste treatment facilities and surrounding communities. In addition, methane emissions can affect air quality by reacting with other volatile organic compounds to form ozone, which can negatively impact human health nearby.
In response to these risks, governments worldwide are implementing measures to curb methane emissions from waste. For instance, the United States plans to propose updated Clean Air Act emissions standards in 2025, targeting methane and other hazardous landfill gases from new and existing municipal solid waste landfills. Similarly, the European Union has tightened its waste management regulations, aiming for significant reductions in methane emissions across member states. Meanwhile, Canada released draft regulations in 2024 that mandate limits on surface methane concentrations and landfill emissions, as well as requirements for methane capture, destruction, regular monitoring, and leak repair.
Cubic, a leading manufacturer of gas sensors and gas analyzers, is dedicated to the provision of efficient methane emissions solutions in diverse sectors, including the waste sector. Based on its mature TDLAS technology, Cubic has developed a high-precision methane sensor, Gasboard-2502, that is capable of achieving a minimum detection limit of 1ppm and a resolution of 0.1ppm, particularly suitable for low-concentration methane leakage background.
Gasboard-2502 features rapid response time with a warm-up time of less than 10 seconds. It guarantees consistent performance in complex environments and severe working conditions by applying the temperature compensation algorithm and self-diagnosis function. It also features an intelligent power consumption design and a lifespan of over 10 years.
Furthermore, Cubic has also developed Continuous Methane Monitoring System that is a state-of-the-art solution for methane emissions monitoring in the waste sector. It is capable of achieving ultra-high resolution and superior methane selectivity, with the integration of high-precision methane sensors. The detection unit is capable of adapting to the impact of variable outdoor environmental factors, such as condensation, pollen, and adverse weather, relying on its intelligent algorithm mechanism that enables flexible temperature and humidity compensation. Concurrently, it acquires real-time comprehensive meteorological data for breach traceability by incorporating a wind direction and speed sensor. It is ideal for field methane sensing scenarios due to the self-sustaining nature of the integrated solar panel with built-in battery, intelligent power consumption management, and scalable wireless communication module.
With superior reliable and credible real-time methane emissions monitoring solutions, Cubic could help operators in waste sector to reduce methane emissions and improve the reliability and credibility of methane emissions management.
