BRANZ. Welcome to BRANZ



 Our Environmental Performance

BRANZ is proud of its Diamond Certification to the Enviro-Mark environmental programme administered by Landcare Research, and our on-going aspiration is to continue improving our environmental performance.

We received our Diamond Certification in November 2009, and at that time, only five other businesses in New Zealand held Diamond certification. There are now 40 businesses with Diamond Certification.

This certification is equivalent to achieving ISO 14001 - the International Environmental standard for good environmental management.

Energy-saving technologies were incorporated in the 2011/12 refurbishment of our site and are mentioned in this 6-minute You Tube clip. The refurbishment was also featured in the August 2012 issue of Trends magazine. (Wait a couple of seconds for page 8 to load and click through to page 15 to see the full story.)

We set ourselves some challenging environmental targets for 2014, and our performance against four of those targets is outlined below.


Electricity consumption to be 15% lower than our predicted usage - taking into account the outside temperature, the number of working days in the month and the number of staff.

Result: Not met. Our electricity consumption was down by 11% against predicted levels. We are looking at other opportunities for reductions.


Waste to landfill - from our gantry bins

80 tonnes.

Result: Met. The weight was 63 tonnes, due in part to the Fire Lab being offline for the first 3 months of the year.  We are on track to meeting this measure in 2015, based on four months data.


Water use 

A water leak caused a large spike in use during 2010. The leak was fixed, and the dramatic reduction in water use was a combination of fixing the leak and water-saving technologies provided by the refurbishments.

Target: 1,000 m3.

Result: Not met. Our usage was 1,541 m3. We had a water leak that was fixed, and our usage for 2015 is on track, based on 5 months of data.


On-site treatment plant

We are not connected to the city sewerage system - we have our own treatment plant on site.

Target: Coliform readings - 8 out of 12 samples less than 10,000 cfu/100 ml and yearly total to be less than 100,000 cfu/100 ml.

Result: Met.
