George,

I concur. The answer is genuine recycled plastic lumber - with no 
wood content. It's easy enough to find although DIYs generally don't 
yet carry it (because the wood composites have taken over the market, 
spurred on by the big timber companies). But for 'real' RPL, go to 
recycledplastic.org for the Plastic Lumber Trade Association to check 
for a manufacturer of 'true' RPL in your area.

Trex and other wood-composite lumbers are not considered recycled 
plastic lumber by the ASTM.
