Quick Answer
The Jenkins Method is a sustainable approach to humanure composting that utilizes a series of aeration and turning cycles to break down human waste, resulting in a nutrient-rich compost that can be safely used in agriculture. This method minimizes pathogen risk and maximizes nutrient recovery.
Aeration and Turning
The Jenkins Method involves a series of 30-60 day cycles of aeration and turning. During each cycle, the compost pile is turned 10-15 times to introduce oxygen and speed up the decomposition process. This is typically done using a mechanical turner or by hand with a shovel. The aeration process helps to eliminate pathogens and odors, while the turning process ensures uniform decomposition and prevents matting.
Pathogen Reduction
The Jenkins Method has been shown to effectively reduce pathogens in human waste to safe levels. Studies have demonstrated that this method can reduce E. coli counts by 99.99% within 30 days. This is achieved through a combination of aeration, turning, and the addition of bulking agents such as straw or coconut coir. The use of bulking agents helps to introduce carbon-rich materials that provide a food source for beneficial microorganisms, which in turn break down the pathogens.
Nutrient Recovery
The resulting compost from the Jenkins Method is a nutrient-rich soil amendment that can be safely used in agriculture. The compost typically contains 10-20% nitrogen, 2-5% phosphorus, and 2-5% potassium. This makes it an ideal fertilizer for fruits, vegetables, and other crops. The Jenkins Method can recover up to 90% of the nutrients present in human waste, reducing the need for synthetic fertilizers and minimizing waste disposal problems.
