Beckenham Industrial Recycling
It's very hard to find any information associated with this Sevenoaks Street address in Beckenham, other than it was registered to A to Z Recycling, who now have an address listed in Neerabup.
These photos were taken in June 2020 and I have no idea how long this site has been disused for. The adjoining property has been completely demolished, with big piles of concrete and building rubble lying along the inside perimeter. Landgate shows it is a different property but perhaps it was used together with this waste treatment and disposal management facility.
