ELIMINATING BREWERY EMISSIONS
Our Supply Chain Director and senior management team are responsible for the implementation of our improvement roadmap towards a ZERO carbon footprint.
We are always on the lookout for ideas and new ways to reduce energy use, packaging efficiency and carbon emissions at our brewery, which is ISO-certified to 14001:2015 benchmarks.
In 2018, our brewery’s heat energy consumption stood at 23.17 kwh/hl, an improvement from the previous year’s 23.23 kwh/hl. The reduction in energy usage is partly due to improvement in hot insulation, which was mainly on heat supply piping and boiler stations. We will continue this initiative in 2019 with more focus on packaging equipment, including bottle washers and pasteuriser body insulation. This can potentially result in energy savings of between 10 to 15%.
We have also installed energy meters for all levels of production to enable more detailed consumption monitoring, while prioritising on focus areas. Other measures include setting up flue gas online monitoring systems to have better boiler efficiency control, as well as upgrading all steam traps and high temperature water purging system, which were aging and inefficient, to a new system to reduce thermal losses.
Our use of natural gas reduced to 18.86 kwh/hl from 19.40 kwh/hl a year ago, while use of renewable energy in the form of biogas increased to 4.31 kwh/hl versus 3.83 kwh/hl previously. The higher use of biogas is due to our upgrading of the anaerobic-stage settlers and biogas blower system, which reduced gas losses at the reactor and recovered more gas for boiler usage.
