@kinsale42@mstdn.games @pikesley@mastodon.me.uk Most metals are recyclable. Gold and silver are the most obvious example. Iron, copper, aluminium, lead, tin and their alloys are recycled at industrial level. Glass production requires recycled glass as one of the inputs. Pieces of old concrete can be used in new concrete. Bricks can be recycled whole or crushed. Gold is recycled because it is not cheap. Make plastic very expensive and people will find ways to recycle it.
