LGI is founder lead business that recently IPO in October 2022. LGI is a renewable energy and carbon abatement company which specialises in the engineering of, and delivery of, solutions in the management, capture and beneficial use of biogas from landfills.

In Australia there are more than 1,100 operating landfills. Of Australia’s large-sized landfills, LGI understands that more than 60% currently recover biogas. There are currently 117 landfill projects registered under the ERF recovering biogas, of which 58 are understood to have biogas-to-energy generation plants installed. LGI's estimates, some 200 landfill sites where biogas recovery systems may be commercially feasible and have not yet been installed, and around another 100 that are yet to be assessed as to their size.
Overview Landfill Gas
Landfills are highly engineered, excavated pits designed to store the waste produced from consumption that isn’t easily reused, recycled or recovered. Landfills are regulated and designed to limit the risk of pollution into the surrounding environment.
Biogas is a natural by-product of the decomposition of organic waste in landfills. Once buried, organic material, such as food, garden, paper, cardboard and wood residues, begin to decompose. The anaerobic (oxygen- depleted) conditions in a landfill lead to digestion of this organic waste by methane-producing bacteria. The resulting ‘biogas’ is composed of approximately 50% methane (CH4), 50% carbon dioxide and a small number of other trace gases and organic compounds. Landfills contribute around 11% of global methane emissions. Methane is a potent greenhouse gas that is 28 to 36 times more effective than carbon dioxide at trapping heat in the atmosphere, over a 100-year timescale. Even after being closed, landfills can generate harmful methane Gas for decades.
A landfill will generate biogas for a prolonged period of time, even after waste has stopped being deposited, depending on various factors such as local climate and site operational practices. Biogas can be produced from waste deposits for more than 30 years. A biogas extraction system can be installed in both closed and active (operating) landfills.
Today LGI has 46 employees and support 26 Bio gas projects on the East Coast of Australia. The majority of LGI customers are Australian local councils. These contracts are long-term contacts usually 20 years plus.
