I was told by my very close neighbour, who used to work in a very large scrap metal yard, that the wastage from the Lotus factory would make you cry.
They had to put all sorts of stuff into the metal fragmentation machine, and take photos of it all being shredded.
The scrap yard is only about a 15 minute drive from my house. It uses various techniques to separate the aluminium, steel etc. I wonder what it does with the fibreglass. I tried burning some badly damaged fibreglass clams, and the black smoke was horrendous. All the fibres were left with all the resin burning ferociously.
