The cash will go fund three upgrades including a second-generation machine for packaging cans in Snap Pack, reducing water usage by around 10% annually as well as a new laser can encoder and an improved can filler and seamer.
CMBC has ambitious targets for sustainability as part of its Together Towards ZERO and Beyond ESG programme.
These include halving its use of virgin fossil-based plastics by 2030 and achieving water usage efficiency of 2.0hl per hl of beer at every brewery also by 2030.
CMBC CEO Paul Davies said: “We take our responsibility as a brewer very seriously and ensuring we reduce our impact on the planet is a hugely important part of this.
“This major investment of more than £10m in Northampton demonstrates our clear commitments to eliminating packaging waste, reducing water waste and improving efficiency at our breweries.
“By taking ambitious action now, we can deliver on our sustainability goals and enable even more of our Snap Pack multipacks to make their way to consumers.”
CMBC has closed a number of breweries within the past 18 months including Jennings Brewery in Cockermouth, Cumbria.
This was following by the news it had sold Eagle Brewery in Bedford to Spanish brewer SA Damm (Damm) for an undisclosed sum.
Meanwhile, less than a month ago (17 October), CMBC announced it had secured a new 10-year partnership with Stonegate.
Starting next spring, it will mean an increased presence of CMBC’s brands including Brooklyn Pilsner and Birrificio Angelo Poretti, across the UK’s largest pub company’s portfolio.
