The Canadians are probably more organic than the EU, since plastic traps carbon for as long as it is around 
while wood does not. Wood rots, burns and generally adds to CO2 compared to plastic. Just look at where all your 
old wooden frames go.

If you look at the whole energy process to make either a plastic or wood frame, it is probably very close. The 
main cost for plastic is the mold for injection molding. But wood needs machines to mold frames. Material costs 
are different now but at one time plastic was much cheaper than wood. With the volatility of oil prices, it is 
probably more expensive.

Plastic lasts longer for the beekeeper and is recyclable or dump it in a landfill and get some carbon credits 
for removing it from the carbon chain and trapping all that CO2.
