It’s almost 50 years since the first Earth Day, and the introduction of the universal recycling symbol. Designed by Gary Anderson, this now famous logo came out of a contest to create an identity which represented the paper recycling process. It has since gone on to become one of the most visible symbols of the recycling movement. As recycling has evolved, so too has the number of signs and symbols on our packaging. Today, there are Green Dots, plastic resin codes, the Tidy Man symbol, and in the UK, the OPRL (on-pack recycling label). While all of these have helped raise consumer awareness and encourage people to take responsibility for their own recycling, we’re still a long way from a perfect world.
