Resource Recycling Technologies (RRT) received this award for excellent collaboration and adaptation to achieve best practice in treating contaminated stormwater at their Woolston metal recycling facility.

Winning actions for stormwater protection:

• The collection, treatment and recycling of used metals is critical for an environmentally sustainable future.
• This business commenced over 50 years ago and is meeting the challenge of increasingly stringent environmental regulation.
• Putting in place an innovative advanced stormwater treatment system designed by e2Environmental and supplied by e2silt0 that achieves a high level of wastewater treatment before discharge into the stormwater network.
• Good systems to test and maintain the performance of the treatment train, including use of external contractors.
• Has made plans and some initial actions to expand this stormwater treatment facility to cover all uncovered areas at the metal recycling facility.

Terry McDonald, Director of Resource Recycling Technologies, said it’s important work. “Metals can produce toxic chemicals and other dangerous substances in the recycling process.”

“At RRT, all products are handled to ensure there are no spillages, leaching or pollution of any kind. We believe this is important in protecting our waterways for future generations,” said Terry.

The panel chose IAG NZ Repairhub Ltd as an award winner for its exemplary use and recycling of stormwater, as well as good stormwater treatment at its carwash in the Hornby car repair facility.
