Philip Wilson, founder of Wilgeo Ltd, has contributed to the landfill engineering sector by authoring the Landfill EA Guide, a key document providing expert guidance on landfill liner materials. Invited by the Environment Agency (EA) to join a committee of experts, Phillip played a central role in developing a framework aimed at resolving ongoing disputes regarding liner material specifications.
The guide offers clear, evidence-based recommendations for the use of landfill liners, which are critical for preventing contamination of surrounding soil and groundwater. It is informed by Wilson’s extensive experience, addressing the technical and regulatory aspects of liner design and implementation.
One of the core objectives of the Landfill EA Guide is to standardise material specifications, ensuring consistency across projects and avoiding future disagreements between contractors and regulators. The guide outlines performance requirements for liner materials, including factors such as permeability, durability, and chemical resistance. It also sets out testing protocols to verify compliance with regulatory standards.
The guide has already been recognised as an important step in improving the efficiency of landfill construction projects. By offering a structured and clear set of guidelines, it helps ensure that materials used in landfill containment systems meet the necessary safety and environmental criteria. Phillip’s involvement in its development reflects his technical expertise and commitment to enhancing landfill management practices.
This guide is now a reference for landfill engineers, regulators, and contractors, serving as a benchmark for best practices in liner specification and performance. Its practical application is expected to reduce conflicts and improve environmental outcomes across landfill projects.
