Wyke Farms is investing £4m in a new anaerobic digestion plant it hopes will transform the cheese maker into the UK’s first carbon neutral major Cheddar brand.

Wyke started work on the plant - which it hopes to be fully operational by autumn 2013 - after gaining planning permission earlier this month.

The company plans to promote its green energy on packs and is exploring carbon labelling with the Carbon Trust.

The move would make Wyke “one of the first national food brands to be self-sufficient in green energy,” the company said in a statement.

The plant will run on waste from Wyke’s Dairy and pig units, via a mile-long pipeline.
