EnviroWaste Ltd owns and operates the Hampton Downs Landfill –  in the North Waikato area  –  a state of the art  modern landfill that will serve the Auckland and Waikato areas for 25+  years.

The design philosophy, site selection process, and landfill management systems aim to ensure that the landfill will cause no adverse effects beyond the site boundary. Hampton Downs also uses landfill gas to  generate 4MW of baseload electricity, sufficient to power several thousand homes.

Stevenson supplies leachate drainage aggregates for the landfill drainage blankets.

This no fines aggregate is a ‘made to order’ product specifically designed to comply with the Envirowaste specification.
GAP65 is also supplied for site roading uses.
