We are continually making progress with regards to improving our waste management. Last year we recycled more than 190 tonnes of material, including steel, aluminium and paper.
At the end of the year, all site personnel participate in a site wide clean up prior to the Christmas break.
In terms of the production process, hydrocarbons removed during the treatment process are recycled for use in the refining process. Water is currently not recycled for use on site.
Discharges to Water
All of the wastewater from process units, storm water, the effluent water treatment plant and the groundwater recovery system is collected in the refinery’s storm water basin prior to discharge.
The wastewater is monitored on a daily basis for a range of contaminants such as oil, sulphide, phenol, ammonia etc. Conditions of our resource consent to discharge wastewater into the Whangarei Harbour contain strict limits on the quality of the discharge.
