Water

Clean, drinkable water is not only the cornerstone to quality brewing – of which beer consists of more than 90% thereof – but is also essential to the wellbeing and economic development of urban centres such as the one our Shah Alam brewery is situated in.

Malaysia’s high water usage per capita and water disruption track record poses concerns and significant materiality towards water waste as a priority concern. To mitigate potential disruptions that can affect production, our water source relies partly on a groundwater tube well located in the brewery, on top of council water supply.

As with our ZERO Carbon Footprint ambitions, the Senior Supply Chain Director and management team oversees implementation of the ZERO Water Waste sustainability roadmap.

Targets

Globally, we aim to reduce water usage at our brewery by 25% in 2022 and 50% in 2030, benchmarked against 2016 performance which is now restated for the 2019 report to include wastewater treatment usage – a more holistic measurement of water utilisation in accordance to Carlsberg Group’s more stringent global measurements.

 

In 2019, water usage for production decreased 12.4% to 4.77 hl/hl as compared to 2018. This was driven by optimisation of water usage in our packaging lines, the replacement of older piping to prevent leaks and improve water losses, and better metering and regular leakage audits to identify and fix leaks immediately.

We have or will undertake the following measures to reduce water usage in 2020:

  • Improve water recovery from the reverse osmosis water treatment process to reduce losses.
  • Recycle and reuse water losses from the reverse osmosis and back-wash process in our water treatment plant.
  • Recycling of final discharge from wastewater treatment plant to be repurposed for non-production usage.
  • Improved shutdown procedure during idling or non-production time in packaging lines, similar to our efforts to reduce thermal energy waste.
  • Optimisation of water usage in packaging lines with a focus on bottle-washing machinery.
