The global trade in plastic waste reveals stark inequalities. For decades, high-income countries like the UK, US, Germany and Japan exported much of their plastic waste to lower-income nationals, often with weak waste infrastructures (OECD 2022, Plastics Treaty Briefing 2023). This practice, often referred to as “waste colonialism,” offloads the environmental burden of consumption onto those least able to manage it. As recently as 2018, Asia imported 70-80% of the world’s traded plastic...

The UK’s recycling rates are around 70% lower than in leading Deposit Return Scheme (DRS) countries with return rates exceeding 90% such as Germany, Finland and Norway. Financially incentivising recycling and reducing waste is important, but our end goal must be a reuse, not throwaway, economy. A DRS that includes glass is key. Glass is infinitely recyclable (although currently energy intensive). Inclusion of glass, as seen in Wales’ proposed model, helps improve resource recovery and reduce...

The idea that plastic will outweigh fish in the ocean by 2050 has become one of the most widely-quoted statistics in environmental discussions. But this disguises the real nature of the problem. Fish make up around 29% of animal biomass on this planet (Ritchie 2024) but calculating their mass in oceans is very difficult. We can estimate algae concentrations from satellite imagery - a proxy for fish food - but actual marine biomass remains uncertain and rather variable. Estimating ocean...
