Greenvale, the potato supplier with 700 staff at sites in Norfolk, Cambridgeshire, Shropshire and Berwickshire, has been acquired by Produce Investment for about £11m. The new shareholder is a holding company called Produce Investment, which belongs to businessman Barrie Clapham. He already has interests in property and tyre recycling and was described by Greenvale's chief executive Alan Owen as a partner for developing the company. "He is not in it for the short term and certainly doesn't need the money," said Mr Owen. "He is a good, practical businessman interested in developing Greenvale. It is business as usual." Greenvale handles about 680,000t a year for processors, caterers and retailers, including Sainsbury's, Tesco and Aldi.
