LoCI's system is designed to increase methane gas extraction from landfills. The software and hardware provide remote monitoring and control, versus historical practices, which require twice-monthly on-site monitoring and manual adjustments to extract the methane.
In anaerobic conditions, as is typical of landfills, methane and CO 2 are produced in a ratio of 60:40. Methane (CH 4) is the important component of landfill gas as it has a calorific value of 33.95 MJ/Nm^3 which gives rise to energy generation benefits. [5] The amount of methane that is produced varies significantly based on composition of the ...
A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide.
The most important requirement is the prevention of the discharge of dissolved methane from untreated leachate into public sewers, and most sewage treatment authorities limit the permissible discharge concentration of dissolved methane to 0.14 mg/L, or 1/10 of the lower explosive limit. This entails methane stripping from the leachate.
Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
Landfill mining and reclamation (LFMR) is a process which excavates and processes solid wastes which have previously been landfilled. [1] The process aims to reduce the amount of landfill mass encapsulated within the closed landfill and/or temporarily remove hazardous material to allow protective measures to be taken before the landfill mass is replaced.

In August 2008, it was reported that after receiving complaints from and pollution from the dump, the Brihanmumbai Municipal Corporation (BMC) had decided to close down a section of the dumping ground and use it to generate 7 to 8 MW of power by methane extraction, adding ₹ 400 million (US$4.7 million) to BMC's revenue.
