Roper's comments in the paragraph above are either misquoted or wrong concerning wood flooring, structural wood and bricks needing to be crushed. Brick, wood and stone are among the oldest truly recyclable materials used in construction. A historic review of old buildings, barns and bridges clearly shows that brick, stones and timber are reused from older buildings. Some of the oldest structures on the planet are built with materials that were recycled from previous structures. One recent example is the Mayflower Barn at Jordans just north of High Wycombe, UK. The barn is clearly built of reused timbers, possibly sourced from the salvage of the Mayflower ship. It is simply a fact of life that historically materials that could be reused were reused.
