Innovative and sustainable resource recovery and management
We all want our future generations to enjoy this incredibly beautiful country. So we need to work together to protect and preserve the one environment we all share, and this is at the very heart of what we do.
Whether it’s turning landfill gas to power, organic waste to compost or returning our beaches to pristine condition, we believe in rolling our sleeves up and doing what it takes to keep New Zealand beautiful.
We have a comprehensive range of proven solutions available to assist with optimising sustainability and are constantly innovating to develop new solutions to meet the individual needs of our customers. Good old kiwi ingenuity, a great team culture and a relentless commitment to preserve New Zealand’s natural beauty and resources, produces the best possible outcomes for our customers and the environment.
EnviroWaste’s facilities and operations have long been recognised as being amongst New Zealand’s most environmentally responsible. We dedicate substantial investment and resources to ensure that we are delivering the highest environmental standards and the most innovative and sustainable solutions.
A few examples of our innovative, first-in-New Zealand initiatives include:
1989: Landfill Gas-to-Electricity – we pioneered the process in NZ of converting landfill methane gas into electricity.Our Hampton Downs Landfill has 7 MW of generation installed, which is capable of supplying the electricity needs of approximately 5,600 households.
2006: Three stream Council kerbside collection - we implemented the first fully integrated ‘three stream’ kerbside collection system. This included the collection and processing of fully comingled recycling, mixed green waste and food waste.
2006: Composting - we installed the first state-of-the-art Gore Cover composting plant in Australasia. Composting has the potential to substantially reduce the amount of food waste going to landfill.
2009: Glass recycling - we developed a method to colour sort glass recycling and were the first in Australasia to use this technology. This method is now recognised as best practice for optimising the successful recovery of glass for recycling in NZ.
2016: We were the first in NZ to treat landfill leachate via reverse osmosis. At our Hampton Downs Landfill, the reverse osmosis leachate treatment plant removes contaminants and recovers up to 300,000 litres per day of high quality purity water fit for reuse or direct discharge back into the environment.
Our partnerships with our customers are an integral part of our DNA. It’s by working closely with our customers that we are able to find the most cost-effective, sustainable waste solutions – solutions that will maximise recycling and resource recovery, so that minimal waste goes to landfill. And by helping our customers to improve their environmental performance, we also help them to make significant cost savings through a reduction in unnecessary spend on waste!
EnviroWaste Services Limited was originally established in July 1995 by combining the waste disposal operations carried out in Auckland by Northern Disposal Systems Limited, a 100% owned subsidiary of Infrastructure Auckland, and the waste collection businesses operated in the South Island by Fulton Hogan Limited.
In November 2001, in a move designed to refocus on its core mission, Infrastructure Auckland sold its 50% shareholding in EnviroWaste to Fulton Hogan. In April 2007, Fulton Hogan sold the company to funds managed by Ironbridge Capital. Under Ironbridge ownership, EnviroWaste made a number of acquisitions that provided us with a new presence in most major locations in New Zealand.
In April 2013, EnviroWaste was acquired by Hong Kong based CK Infrastructure Holdings Limited.
CK Infrastructure Holdings is the largest publicly listed infrastructure company in Hong Kong with global diversified investments in Energy Infrastructure, Transportation Infrastructure, Water Infrastructure, Waste Management and Infrastructure Related Business. Operating in Hong Kong, Mainland China, the United Kingdom, the Netherlands, Australia, New Zealand and Canada, it is a leading player in the global infrastructure arena.
