reduction in waste disposal in 2017 vs 2016
Our updated Environmental Policy and accompanying operational manual provides operational manual provides guidance on water management.
Water stewardship is the primary responsibility of the Management team, particularly the Supply Chain it comes to managing permits for water extraction and discharge.
Together, we will work to implement and refine our ZERO water waste roadmap that includes the continued roll-out of existing wastewater recycling technologies and the search for new technologies, since the most waste occurs while cleaning our equipment during the brewing process.
Water Efficiency and Waste Water
The key to further improving performance in this area lies in driving concerted efficiency by everyone in the organisation.
In 2017, our water efficiency improved by 11.07% to 3.66 hl/hl from 3.69 hl/hl in 2016.
Some of the key initiatives implemented included refurbishment of the filtration system with nozzles and filter media replacement; optimised backwash frequency with increased in backwash cycle time; optimised RO system with increased in recovery to maximum possible which in turn reduced the discharge to waste; and recycling some small portion of backwash discharge water and reusing for second backwashing cycle before being discharged to drain.
As a result, our water treatment losses were reduced to 26% of total water intake in 2017 versus 34% a year earlier.
