LOGISTICS giant Walon UK has turned to wind power to help improve the efficiency of its computer barcoding system.

Antennae at the company's Royal Portbury Docks depots, near Bristol, which relay information from barcode-reading handsets, are powered by the wind, eliminating the need for miles of cables. The company, which provides vehicle preparation and delivery services, uses the handsets to locate and process vehicles.

Walon business systems manager Tim Wiseman said: 'Running power cables all over the compound would have been very disruptive and horrendously expensive.'

The first of five wind-powered aerials has been put up to complement other 'mains-powered' aerials around the site.
