Earth Bin™ Frequently Asked Questions

• Modular and expandable design allows flexibility in application
• Bio-filter processes odors and accelerates the compost process
• High rate composting reduces volume and stabilizes material quickly
• Powered auger is thoroughly effective for mixing and shredding most foods
• Insulated design allows for operation under winter conditions

How much organic waste must an institution generate to use the Earth Bin™?

For on-site composting, the Earth Bin™ is capable of processing as little as 300 lbs (120 kg) per day or as much as 2000 lbs (250 kg) per day. The modular design of the system allows it to be adapted to a wide variety of applications and configurations simply by adding more Earth Bins.

What if your organic waste stream increases?

Expansion capability is one of the key features of the Earth Bin System™. By virtue of its modular design, the system is ideally suited to incremental capacity increases. This system is a perfect application for gradually introducing composting to the institutional organic waste generators.

What are acceptable Materials for Composting?

The system is designed to process Kitchen prep waste and plate scrapings. Green garden waste and manures will easily compost in the system. Meats, cheese, and other fatty foods should be kept below 15% of total waste input. Avoid adding large pieces of meat, fats or oils to the system.

How cold can it be and still maintain compost temperatures in the Earth Bin?

The Earth Bin has been installed in some very cold locations. It may need supplemental heat if the temperature remains below 10F for more than 7 days. The aeration system should be shut down during cold weather.

Do I need a shredder for the Earth Bin?

If you are composting organic waste that is collected with cardboard, biodegradable utensils or biodegradable bags then we recommend a high torque type shredder to prepare the waste for composting. If it is only food waste and pre ground wood chips, then a shredder is not required.
