Beeswax is a valuable commodity.  There are various ways to increase the
harvest.  When uncapping do not just take off the caps but run your knife down
the side bars thus taking extra wax from each side as well as neatening up the
combs.  Try using top bar hives.  Cut out the best looking portions of honey
comb for sale as cut comb at a premium price.  Press the honey from the
trimmings.  You won't get it all out but you can put the pressed wax back in
the hive it came from for the bees to fill new combs.  When cleaned by the
bees you can remove the wax and turn it into candles, polish etc.
