  • Concrete recyclingWikipedia

    Concrete recyclingWikipedia

    Concrete aggregate collected from demolition sites is put through a crushing machine. Crushing facilities accept only uncontaminated concrete which must be free of trash wood paper and other such materials. Metals such as rebar are accepted since they can be removed with magnets and other sorting devices and melted down for recycling elsewhere.
