Measures to conserve water in response to water stress
Reducing the amount of water we use in our plants is a major issue. The Kirin Group has pursued water conservation through recycling and other means, in addition to initiatives based on using water only when and as much as needed.
Focusing on water stress in the basin regions around our plants, we are installing and operating water-saving equipment according to the level of water stress.
Cascading industrial water
In plants, much of our water usage is for washing and sterilizing processes for equipment and pipes. In addition to establishing frameworks and mechanisms to confirm and assure the washing, from a quality perspective, we also strictly control water flow rate and velocity to ensure that we do not waste water. We also actively pursue the re-use of water, depending on the purpose.
For example, the rinsing water that we use in the final step of the pipe and equipment washing process is still relatively clear, so we can use it again for the initial process of pipe washing. In this way, we have implemented a cascading system of water use in which we repeatedly use water that we have previously used in washing, according to the quality of the water. In actuality, considerable knowledge on how to use equipments is necessary to guarantee that we are properly washing the equipment and pipes, such as achieving the right balance of the amount of water we can recover and the amount of water we can use, as well as the timing of recovery and use.
The Kirin Group is achieving a high level of water conservation by sharing and accumulating various different types of expertise.
Advanced water treatment equipment
Lion is committed to exploring innovative ways to improve water management within the communities it operates. In 2009, Lion commissioned a water recycling plant for its Castlemaine Perkins Brewery – setting out to halve the water used in brewing their classic brand, XXXX Gold.
The two main uses for water in brewing are water used in making the beer itself – plus water used in the brewing process, which is used in non-product related processes, such as cleaning, cooling, and pasteurizing. In 2009, Lion partnered with the Queensland Government to install a reverse osmosis plant, to recover waste water and minimize our reliance on mains-fed town water. In 2019, the plant generated more than 240 million liters, the equivalent of 96 Olympic-sized swimming pools. On average the brewery recycled approximately 4.7 million liters of water per week in 2019. Vitally, the plant enables Lion to produce XXXX Gold at a ratio of 2.5 liters of water for every liter of beer produced – which is approaching world class levels of water efficiency.
Lion is sharing this technology within the Kirin Group, and we are now using it at Kirin Brewery’s Kobe Plant.
