The Safe Enzyme Maker transforms certain types of kitchen waste into bio-enzymes that can be used as environmental cleaning products and plant nutrients. The simple bucket offers many features that transform this type of composting into an easy, neat system ideal for home use. The bucket is easy to refill and has minimal contact with the air. The materials are mixed when the bucket is sealed to avoid mold and fungus. An automatic gas outlet valve decreases pressure and prevents the bucket from exploding. Multiple buckets can be stacked to free up space.
