Cycling and recycling
Technology has long been an essential consideration in public discussions of the environment, with the focus overwhelmingly on creating new tools and techniques. In more recent years, however, activists, researchers, and policymakers have increasingly turned to mobilizing older technologies in their pursuit of sustainability. In fascinating case studies ranging from the Early Modern secondhand trade to utopian visions of human-powered vehicles, the contributions gathered here explore the historical fortunes of two such technologies—bicycling and waste recycling—tracing their development over time and providing valuable context for the policy successes and failures of today.

Challenges in Metal Recycling
Metals are infinitely recyclable in principle, but in practice, recycling is often inefficient or essentially nonexistent because of limits imposed by social behavior, product design, recycling technologies, and the thermodynamics of separation. We review these topics, distinguishing among common, specialty, and precious metals. The most beneficial actions that could improve recycling rates are increased collection rates of discarded products, improved design for recycling, and the enhanced deployment of modern recycling methodology. As a global society, we are currently far away from a closed-loop material system. Much improvement is possible, but limitations of many kinds—not all of them technological—will preclude complete closure of the materials cycle.

Designing a circular carbon and plastics economy for a sustainable future
The linear production and consumption of plastics today is unsustainable. It creates large amounts of unnecessary and mismanaged waste, pollution and carbon dioxide emissions, undermining global climate targets and the Sustainable Development Goals. This Perspective provides an integrated technological, economic and legal view on how to deliver a circular carbon and plastics economy that minimizes carbon dioxide emissions. Different pathways that maximize recirculation of carbon (dioxide) between plastics waste and feedstocks are outlined, including mechanical, chemical and biological recycling, and those involving the use of biomass and carbon dioxide. Four future scenarios are described, only one of which achieves sufficient greenhouse gas savings in line with global climate targets. Such a bold system change requires 50% reduction in future plastic demand, complete phase-out of fossil-derived plastics, 95% recycling rates of retrievable plastics and use of renewable energy. It is hard to overstate the challenge of achieving this goal. We therefore present a roadmap outlining the scale and timing of the economic and legal interventions that could possibly support this. Assessing the service lifespan and recoverability of plastic products, along with considerations of sufficiency and smart design, can moreover provide design principles to guide future manufacturing, use and disposal of plastics.
Four future greenhouse gas emission scenarios for the global plastics system are investigated, with the lead scenario achieving net-zero emissions, and a series of technical, legal and economic interventions recommended.
