Carlsberg Britvic wanted to decrease its water use. “As a beverage company, water’s obviously critical to us. It is part of everything we do,” says Calvin Winch, Head of Supply Chain Sustainability at Carlsberg Britvic.
At the company’s bottling plant in Beckton, East London, the company saw a potential of reducing water in its bottle rinsing – a high water-use area.
It partnered with Grundfos to develop a closed-loop system that filters, cleans and treats used process water to a super-high-quality water for reuse at the bottle rinse carousels. It saves the company about 60 million litres of water a year – the amount that 500 UK households use in a year.
The method is significantly more economical and environmentally friendly than traditional wastewater treatment, requiring considerably less energy, chemicals, water and labour. “There’s a lot of electricity, chemicals, time and effort gone into making that water in the first place, so we want to reuse it as much as possible before it goes down the drain,” says Calvin Winch.
