it's been interesting to note that materials which were hitherto considered as 'wastes' are now becoming major construction materials; rice husk, empty bottles, and many others. Take rice husk for instance, when burnt, the ash can be used as material for achieving concrete that has the quality of being less permeable to moisture. What do you think out there?

tree tops used to be left in the woods
Now they are on roof tops and walls (OSB) or oriented strand board.

Anyone ever see plywood that was sewed together? I think I can remember seeing some in an old house. This before glues were introduced that were stronger.

Once they found out how to make glue 10 times better
it became possible to glue wood chips together.
