IN-VESSEL COMPOSTING SYSTEMS
EARTH FLOW™
The award-winning Earth Flow™ automated mixing system shreds and aerates compost while gradually moving the material toward the discharge end of the vessel, requiring little labor beyond loading and unloading. The Earth Flow™ is guaranteed not to cause odor problems when operated according to specifications. The Earth Flow™ is America’s top-selling in-vessel composting system because it has been proven for over 20 years to be effective, long-lasting and easy to operate.
We have multiple finance partners for the Earth Flow, which enables qualified customers to get a system with $0 cash down-payment, financed over 3 to 7 years.

CONTAINERIZED COMPOST SYSTEM
As an operator, your challenge is to keep regulators, neighbors and compost users happy with your facility. The CCS is designed to help you succeed. Composting takes place in controlled batches with airtight vessels (CompTainers™) that can be moved and emptied by roll-off trucks. Each in-vessel composting system is closely controlled to optimize decomposition, meet regulatory requirements and minimize odors. The unique aeration system can integrate up to 50 CompTainers into a single system. Add a small building for receiving and mixing plus a biofilter to remove odors, and you have a completely enclosed composting system at a fraction of the cost of other in-vessel composting systems.

EARTH CUBE
As of May 15, 2023, the Earth Cube is no longer available due to supply chain and manufacturing challenges. We will honor any previous grant-funded proposals or outstanding orders, but we will no longer process new orders.
GMT developed the Earth Cube for small scale community composting organizations and educational institutions. As part of our commitment to community and educational organizations, in the summer of 2023 we will release a DIY video instruction resource to enable people to make their own Earth Cubes.
