Overview

Managing landfill gas at Kimbriki: The path to best practice. Belinda Lau, Kimbriki Environmental Enterprises


Details

The Kimbriki Resource Recovery Centre is located on Sydney’s Northern Beaches and incorporates a range of resource recovery facilities and a non-putrescible waste landfill. Approximately 3.5 million tonnes of waste has been landfilled at the site since operations commenced in 1974. In 2012 an action plan was developed and steps taken to aggressively reduce landfill gas emissions at the site, which, in addition to a conventional gas extraction and flaring system, included progressive installation of horizontal gas collection trenches (during landfilling) and the strategic application of biocovers. These measures have led to a >55% reduction in landfill gas emissions at the site.
