Unfortunately, the container had a 6 inch split, which might have still held soil but I wanted to make sure. The previous owner of the container regarded a broken plastic container as finished, threw it outside his house and probably bought another.
All too often, plastic items are thrown away just because they have a split in them. This is common amongst containers that are meant to carry water; buckets and watering cans.
When recycled these items will be shredded into pellets and melted into new plastic items, a waste of energy.
A far better way of recycling split plastic items is to renew them through plastic welding.

After 10 seconds or so in a flame the metal will be hot enough to weld with.
(Sorry for the paucity of photographs in this instructable but I only got the idea for the instrucatable just after I completed the task.)
After you have performed your tack welds you can then seal up the split with broader strokes up and down the split. Imagine buttering a piece of bread and move the plastic from both sides of the split, over and along. Don't let the metal sink into the plastic otherwise you will thin and weaken the plastic. You just want to get the surfaces of both sides to fuse together.
Reduce, Reuse, Recycle.
Have a Green Day!
