Earthmaker 120-Gallon Three Stage Aerobic Composter

very large plastic compost bin

Among plastic compost bins, the Earthmaker 120-Gallon Three Stage Aerobic Composter is one of the biggest. In fact, it’s downright huge. In addition to its size, the manufacturer claims that you can make finished compost with their bin in as little as three months.

The Earthmaker Aerobic Composter is billed as the first continuous-cycle compost bin, which means that rather than having to spend loads of time aerating and mixing the material in the bin, this bin (it is actually a series of connected compost bins) should make it almost effortless.

The Earthmaker bin is comprised of three separate chambers. As the material begins to break down you can remove the floor panel from one chamber so it drops into the lower chamber which avoids the problem of adding fresh waste to partially finished compost. You just re-insert the floor panel and then you can add more fresh material to the top compartment without affecting the partially finished compost  below.

Pro’s & Cons of Earthmaker 120-Gallon Three Stage Aerobic Compost Bins:

  • The Earthmaker is a bit more expensive than most plastic compost bins but some people report that they feel it’s worth the extra cost knowing that one bin will meet all their composting needs.
  • There is a potential concern in not having the compost mixture in contact with the ground until the third stage of the composting process, potentially reducing the number and diversity of organisms that can enter the mixture to aid decomposition.
  • One problem some homeowners have with plastic compost bins is their smaller size. This bin is so large that it’s hard to imagine it not being big enough for a family of four.
  • The bin is fairly contained so flies and unwanted critters shouldn’t be much of a problem.
  • It is fairly easy to assemble
  • For those with very little space, this bin might be a bit too large and conspicuous.
  • This is a great compost bin for people who want a hands off, no fuss, no mess approach to composting. It’s easy, it’s self contained and it works.
