There was a takeaway in Bristol on the TV last night, with an article about their new tiffin boxes for the takeaways. You either buy one for £10 or get charged £10 for it which is credited when you bring it back.
The idea is to cut down on the amount of plastic waste - very admirable. But it left me wondering just how much CO2 is produced and how much environmental damage is done by making a reasonably complex steel box, as opposed to a bit of extruded plastic. The mining of the iron ore, shipping the iron ore, smelting, making the steel, fabricating the steel etc. Huge amounts of energy, CO2, and waste goes into making 1 metal tiffin box.
Clearly the metal tins are re-usable but just how many times do they have to get re-used before it's a "win"? And then they looked at alternative plastic boxes, made from fully biodegradable plastic made from vegetables! Which I would imagine are a million times better, and yet the dungaree wearers were all there in force with their precious tins.
