Peter Moon

Peter Moon is President and Principal Engineer of PME / O2Compost, and is a licensed Professional Engineer in the State of Washington. Peter has as Bachelor's Degree in Geology and a Masters of Science in Geotechnical Engineering from U.C. Berkeley. He has 25 years of consulting (i.e. problem solving) experience. Prior to 1989, Peter had never even heard the word composting, let alone study the subject school. However, during the past 15 yaers, Peter has learned a great deal about composting and everything he knows he has learned by doing it. Having studied, tested and resolved nearly every mistake imaginable, he understands what works and more importantly, what does not work. His hands-on experience has led to a career in training others the How-To's of on-farm composting.

Peter's passion for composting coincided with the implementation of federal water quality regulations and an increased awareness that organic waste materials need to be properly managed to better protect the environment. At this point, Peter works with nearly every variety of organic by-product, however, his principal areas of interest are composting horse manure, grape pumace, golf course green wastes, and exotic wastes such as zoo manure, mink wastes and farm mortalities. As an adjunct to teaching the composting process, Peter also works closely with vermi-composters and compost tea users.

He recently designed and constructed a 4-bay aerated compost system for a 12-horse stable in Snohomish (Liberty Bell Farm) as a way to further gain experience and to "Learn by Doing". Harold is very practical in his approach, with an emphasis on efficiently using both available space and construction materials.

His background includes 25 years in the paper industry as an environmental engineer and 4 years working as a consultant in the compost industry. At home, Harold manages an abundance of nitrogen-rich farm animal residuals from 5 horses and other small animals.
