Made in Germany where composters need to withstand harsh winters year after year, the Thermo King 900 Jumbo Composter is not only built to last but is also the largest composter in its price class.  Made of an industrial grade copolymer, withstanding years of severe winters is not a problem and the 4mm thick walls help insulate the material breaking down inside.   

The revolutionary copolymer plastic walls and top have infused air bubbles which work in a similar way to a double paned window where cold outside air and warm indoor air do not pass easily through the middle air space. The air bubbles in our composter are locked in a vacuum within the walls, thus making it difficult for the composting heat to escape, and to some degree, reducing cold winter air from entering the composter.
Developed for anyone with a larger yard or unusual volumes of leaves, the 240 gallon capacity is one of the largest in its class. The hinge on the lid allows quick access for adding less material, but removing the top is simple when needing to add large amounts of leaves or grass.  The lid when open stands up on its own.  When closed, the lid can be locked into place.  

The neutral green color fits well into any back yard setting and the modified octagonal shape (8 sides/panels) are a visual improvement over a standard square shape and also add considerable strength & stability.  The 2 compost removal doors allow easy access for work with a shovel.  They are 12” tall and nearly 30” wide.  

Assembly Note:
Assembly is simple taking under 30 minutes and requires no tools whatsoever.  Make sure to place on level ground for best results.
