I wanted to issue a warning about using plastic bins as part of your worm composting system. In short, I no longer recommend doing it. Instead, build your own worm bin out of wood or other recycled materials.
I see many other sites and books recommending the use of a Rubbermaid compost bin for your worms, heck, I even used to recommend it, but not any more. The video below helps demonstrate why I’ve had a change of heart…
Note – The Rubbermaid compost bin in the above video did not have any holes drilled in it for drainage, so it exaggerated the disadvantages of using plastic. However, I’ve spoken with several professional worm farmers, all of which said, “AVOID using plastic worm bins!” These guys make a living off of composting worms, so I don’t take their warning lightly.
On that note, I want to be clear about the underlying message in this article – I am NOT saying the use of a plastic worm bins does not work. They do “work”, but they’re not ideal and there are more effective and cheaper options.
To build a successful worm composting system, you want to consider several key factors, including oxygen, moisture, food, bedding, pH, temperature, etc. The disadvantages of using a plastic worm bin primarily affect three of these factors – oxygen, moisture, and temperature.
Our landfills already have enough plastic in them, let’s not add to the problem. Instead, be a true Compost Junkie and build your own worm composting system by upcycling material that you have lying around your house. Or visit a thrift store (the Habitat for Humanity Restore is a great place to start) and purchase some gently used construction materials (e.g. wood planks, cupboard doors, shelving units, drawers) and then start building!
