this is my current project. building my compost bins. i purchased these bins a few years before we moved from the last house. it is made of recycled plastic - extruded into plank like lengths. this was pre-trex days - and cost me about $250 for the 2 bins (only one is shown the pic).
its unrottable (new word i invented) and did a decent job at the last house.
so by the end of this weekend - i am betting i will have 2 bins ready to go. its important i get this done - as my sons first scout merit badge task is to build a compost pile and get compost in 90 days.
