Sugarcane bioplastic is the first plastic ever made from a fully renewable origin, and, even better than this, to make it they actually reduce the worlds carbon in the process. PCR plastic reuses single-use plastics (such as drinks bottles and packaging) which would otherwise be disposed of in landfill sites, greatly reducing landfill waste and plastic pollution. It also uses less energy and fossil fuels, protecting the environment from excess pollution, greenhouse gas emissions, and overuse of resources.
