At my company, TerraCycle, we wanted to know if it could also motivate people to reduce packaging waste. For years, we have used social media as a tool to help shift commonly held perceptions about product and packaging waste. Whether that means sharing pictures of “upcycled” art made with product packaging, promoting the sustainability efforts of a recent partner or sharing with our users intriguing “Eco-Facts” about their waste, social media sites like Facebook and Twitter have given us a variety of platforms (and access to different audiences) to inspire change and motivate people to recycle traditionally difficult-to-recycle waste streams.
