A Norfolk wastewater company which works with one of the UK’s oldest whisky distilleries has grown more than 40 pc in the past year.

Norwich-based Alpheus Environmental said it has had “an exceptional year”, growing its turnover by 44pc in the last 12 months. 

The firm, which earlier this year signed a five year contract with the medieval Glenmorangie Distillery in Tain, Scotland, has also expanded its team by 29pc in the same period.

Declan Maguire, managing director at Alpheus, said he believes the recent growth has been down to the unique anaerobic digestion technology at the centre of the business.

It works by using microorganisms to break down organic material in the waste liquid, creating renewable fuel and helping to treat the water.

Mr Maguire said: “Anaerobic digestion has been around for a very long time but has seen a surge in recent years to reduce operating costs and achieve increasingly tough sustainability goals.

"Despite some government backtracking on net zero targets, the continued growth in engagement from certain sectors proves that UK businesses will lead the charge to net zero by 2050."
