material flow analysis

A new study of UK plastics flows co-authored by TransFIRe researchers Michał Drewniok and Jonathan Cullen shows that 1/3 of related green house gas (GHG) emissions could be reduced by increasing recycling capacity and reducing demand. Plastics are pervasive. We use them every day in our phones, laptops, clothes, and cars. Plastics have also been found in the most unlikely places, from the human bloodstream to the bottom of the Mariana Trench. Public concern about the use and disposal of plastic has soared in recent years, catalysed by David Attenborough’s documentary pleas and enduring images of seahorses grasping Q-tips circulating on social media. But alongside issues of marine and terrestrial pollution sits the less visible contribution of plastics to climate change. Greenhouse gas emissions are released when heat is generated for the chemical reactions required to manufacture plastics, and from those reactions themselves. Emissions also result from the management of waste [...]
