A Johnson-Su Bioreactor (JSB) is a passive composting system that produces high-quality compost in a short amount of time without turning or odors. It is named after its inventors, Paul Johnson and Alan Su, who developed it in the 1990s.
JSBs are typically made from wood or plastic and have a series of perforated pipes running through the center. Composting materials are layered around the pipes, and air and water are circulated through the system using a fan and pump. This creates a favorable environment for microorganisms to thrive, and the compost breaks down quickly.
JSBs have a number of advantages over traditional composting methods. They are faster, cleaner, and easier to maintain. They also produce a more consistent and nutrient-rich compost.
*Here are some of the benefits of using a Johnson-Su Bioreactor:*
* *Fast:* JSBs can produce finished compost in as little as 4-6 weeks, compared to several months for traditional composting methods.
* *Clean:* JSBs are enclosed, so there are no odors or pests.
* *Easy to maintain:* JSBs require very little maintenance. Simply add composting materials as needed and water the system occasionally.
* *Nutrient-rich compost:* JSBs produce a compost that is high in nutrients and beneficial microbes. This compost can be used to improve soil health and increase crop yields.

*How to build a Johnson-Su Bioreactor:*
There are many different ways to build a Johnson-Su Bioreactor. Here is a basic overview:
1. Choose a location for your bioreactor. It should be in a shady spot with good drainage.
2. Build a frame for your bioreactor. The frame can be made from wood, plastic, or metal.
3. Line the bottom of the frame with a mesh or perforated material to allow for drainage.
4. Insert a series of perforated pipes into the frame. The pipes should be spaced evenly and run from the bottom to the top of the frame.
5. Add composting materials to the bioreactor, layering them around the pipes.
6. Water the composting materials and cover the bioreactor with a lid.
7. Monitor the bioreactor and add water as needed. The compost should be moist but not soggy.
Once the compost is finished, you can remove it from the bioreactor and use it in your garden or on your lawn.
