2021.10.01 EASYJET Jr.
Waste shiitake mushroom bed composting factory (Introduced to: Shiitake Production Facility Company K)
By recycling all waste mushroom beds after cultivation, they were able to achieve zero emissions and reduce processing costs.
| Place | Wakayama Prefecture |
| Processed Material and Amount | Shiitake waste mushroom bed 3 tons/day |
| Overview | By recycling all waste mushroom beds after cultivation, they were able to achieve zero emissions and reduce processing costs. |
Measures and Effects
| Increase processing amount by expanding facility/equipment | They built a new facility and started a composting business. |
| Increase processing amount by improving aeration | By adopting a high-pressure aeration system and efficiently composting in a limited space, they were able to increase the amount of processing compared to typical systems. |
| Reduce costs by saving labor | By eliminating the turn over work, it became possible to operate the facility with a small number of staff, do low-cost processing. |
| Improve compost quality by improving aeration | Difficult to decompose woody materials are composted in a short period of time using high-pressure aeration. It achieves high quality composting without odors. |
Company K has the capacity to make about 1,300 mushroom bed blocks per day, and culture them to use in cultivating shiitake mushrooms.
Before, they simply discarded waste mushroom bed blocks after cultivation, but by introducing our technology, they became able to recycle all blocks they produced, and supply high quality compost.
First, waste mushroom bed blocks from the shiitake factory are shredded with a shredder and packed in flexible container bags.
Flexible container bags filled with waste mushroom beds are stacked on pallets and lined up.
Insert one EasyJet Jr. into one flexible container bag.
After a while, fermentation starts and the temperature rises.
It is not necessary to do turn over during the fermentation period. Rather, it is enough to just change the position where EasyJet Jr. is inserted once a week.
Composting with this method does not require a dedicated building, so it can be installed even in the dead space of a factory.
This setup can be expanded or relocated, making it possible to build the optimal composting plant for the scale.
In preparation for introduction, we did preliminary composting tests at our in-house test facility, and made a proposal for a plant based on the test data.
