Many solutions to plastic pollution work as pilots. The harder question is how to scale them.

This case study from UNDP's Global Plastics Innovation Programme (GPIP) looks for answers in China. It documents 13 solutions across the plastics value chain, from bamboo alternatives and reusable courier packaging to smart recycling and blockchain traceability.

Each case sets out the problem, the innovation, what drove it and the lessons learned. It offers policymakers, entrepreneurs and practitioners tackling plastic pollution a source of inspiration, a practical guide and a call to work together towards a circular future.
