Active Landfill Gas Interception

The initial scope involved a detailed review of the quarry extent, gas migration potential, gas generation and feasible interception methods. Several rehabilitation and management options were considered during the conceptual design, including biofiltration systems, in-situ bio-enhancement and flaring technologies. Importantly, the system needed to demonstrate immediate compliance and acceptable gas risks to off-site land users to facilitate endorsement by the Auditor and regulator.

Construction was completed in May 2023.
