Walkers is to launch a nationwide recycling scheme for crisp packets following calls for the company to introduce environmentally friendly packaging. The crisp packet recycling scheme - the first nationwide initiative of its kind in the UK - is due begin in December, Walkers has announced. A campaign that saw environmentalists sending empty crisp packets back to Walkers using its freepost address garnered attention last month and led Royal Mail to plead with activists to put the packs in envelopes as failure to do so would cause delays to the mail sorting system.
