Manufacturer to collect and repurpose packaging after campaign against firm’s waste.  Walkers has agreed to offer a free national recycling scheme to stop millions of empty crisp packets ending up in landfill in the UK every year after consumers heaped pressure on it to change its plastic packaging. A social media campaign asking crisp manufacturers to make their packaging recyclable led to Royal Mail issuing a plea to members of the public last week to put empty crisp packets in an envelope before posting them back to the company.
