An Environmental Overview

The majority of our precious metal products are produced by recycled waste from Jewellers and industry along with local mines from within Australasia.

Alluvial gold from the South Island NZ is another source of gold. Our mined gold supply is sourced from miners whose operation complies with Department of Conservation protocols.

These products, being impure or of an unknown composition require refining. The refining process involves burning or melting the material and then chemically refining to a pure state in our Laboratory. The pure gold, silver, palladium and platinum is then recycled into fabricated product.

The precious metal recycling program is the foundation of 80 years of successful business and our edge in the market. We have fine tuned the refining processes into an environmental sustainable operation. For example: The melted and burnt exhaust is evacuated through afterburners and water spray scrubber systems. The laboratory air extraction system has automatic PH dosing system that is monitored and recorded daily. The Accelerate R & D Program grant from Tech NZ allowed Morris and Watson to investigate and conduct a pilot study to remove the heavy metals and recycle the wastewater generated within the treatment facility. The Water Treatment Plant is due for commission in 2014. At present the waste liquid is removed from the premises and disposed by an accredited company.

All waste water from other production areas are run through sediment traps before being discharged. The Lost Wax Casting process ensures the majority of the wax prior to the burnout stage is steamed out and not burnt into the environment.

MW have a comprehensive system of rain water usage via roof catchment and tank storage that is useful for melt machine cooling and recycling throughout the factory.

All our systems are documented with an Environment Management Plan (EMP) which was prepared by consultants under the guidance of the management team. The EMP is monitored and complies with Auckland Council protocols.

Due to spikes in our production there are times when we purchase pure metal from internationally accredited suppliers.
