Plastics are ubiquitous, but problematic from a whole life cycle perspective. Nature Sustainability asked four experts to present their views about the ongoing plastics crisis.
Policy making is entering a phase of more transformative strategies targeting the full life cycle of plastics, argues Patrick Schröder.
When strategizing the design of sustainable polymers, the timescale must be an essential dimension, that is, even for bio-based and/or biodegradable plastics their resource utilization should not outpace resource regeneration, argues Eugene Chen.
End-of-life plastics conversion is crucial to reduce plastic pollution and realize a circular economy, argues Ding Ma.
The rapid increase in plastics waste is worrying, but approaching sufficiency in a broader sense can tackle much more than plastic waste streams only, argues Sylvia Lorek.
Principles underpinning the 2030 Agenda — indivisibility, integration and universality — can safeguard against inaction or unsustainable practices but have not yet come into effect. We propose measures to strengthen alignment with them as the world gears up to accelerate implementation at the...
Many coral reefs suffer from the effects of overfishing, which threatens biodiversity and erodes human livelihoods. A study now reveals where fished reefs boost their total productivity, providing a means of resilience.
The upcycling of plastic wastes to realize plastics circularity is obstructed by the presence of chlorine impurities. Now a conversion strategy addresses this problem and paves the way to upcycle chlorine-contaminated plastic wastes.
Changes in driving behaviour could offer solutions to reducing transport emissions. Classification of driver aggressiveness based on vehicle trajectory data is used to estimate transport emissions associated with differences in car-following behaviour in China from 2013 to 2050. This analysis...
Nitrogen requirements and usage vary across maize, wheat and rice systems in Ethiopia, Malawi and India. Analysis of these systems indicates that targeted nutrient management strategies could increase the efficiency of nitrogen usage, helping to address fertilizer shortages and reduce the...
