From Barry Cash
Anthony Castaldo says we need a “cheap solar-powered device that can produce neat carbon pellets by the megaton” (Letters, 1 August). The machines are called trees and they store carbon in chipboard and paper. Instead of recycling or burning these products, I suggest we bale them up and cover them in thick recycled plastic – there seems to be quite a bit around that we don’t reuse. Then all we need to do is store the bales somewhere where they won’t be damaged.
I suggest old mines or quarries in the UK, deserts elsewhere, Antarctica – or, as he suggests, the bottom of the sea.
