Test the best!
At a Colorado garden the Earthmaker and the Bio Orb are selected as the best then put to test.
The test was conducted in 2009 (we've only just stumbled upon it!). CLICK HERE to check out the videos. The result is very favourable for the Earthmaker but the trialists shoudl have added much more material over time. The Erathmaker's continuous cycle composting process is designed to to suit our lifestayles - we create kitchen waste every day and need to add it to a pile in a way that does not mix it up with maturing copmost. The Bio Orb, like tumbling drum systems, makes one batch at a time so you need at least two.
