What is.....
A S R ?
Answer Everything left after the metal is
removed from a shredded car- about
25. Around 400,000 tonnes
landfilled in UK/yr.
It is usually separated into different sized
fractions, and at the beginning of the project it
was not known what materials were in each, or the
relative volumes.
