It is easy to see how plant and animal/ fish resources can be regenerated. But what about metals?
The iron ore that is mined from the earth was typically formed millions of years ago – the exception being where recent volcanic eruptions release iron-containing magma. So rather than talking about regenerating metals, we should talk about recycling metals.
Do we recycle as much – indeed all – the metal we discard?
The FT reports “The UK produces 10mn-11mn tonnes of scrap steel each year of which less than 3mn is recycled. The rest is exported as there is not enough demand from domestic steelmakers.” https://www.ft.com/content/1e273a6d-2683-419c-9567-91281df3c648 However as the UK switches from coal burning blast furnaces to green electric furnaces, which smelt 100% recycled steel, that demand will grow.
What about newer metals such as lithium, which we have only recently begun to exploit? Even if we did recycle all that we discard, growing demand for lithium still means more raw ore will be mined. Can this be sustained – and sustained in a way that does it exploit people nor damage their land and ecosystems?
“Q. How can I recycle my lithium-ion batteries?
- You can take your used batteries to designated collection points such as local authorities, civic amenity sites, retailers, and waste electrical and electronic equipment (WEEE) recycling sites that hold an ABTO license.” https://www.cellcycle.co.uk/a-guide-to-lithium-ion-battery-recycling-in-the-uk/
