O2Compost SOQ Comprehensive

Puyallup Research and Extension Center 18 May 2015 To Whom It May Concern I have worked with the WSU, WORC, and Ecology Compost Operator Training class for over 15 years. This program provides training in proper operation of compost facilities. As part of this program we discuss proper composting techniques. We also discuss all types of feed stock from onfarm manure materials through fish carcasses as compost feed stocks. The class covers several sections on odor management including the biology of odors and managing composting for odor control. One method of odor control covered in the composting class discusses the use of an aerated static pile for odor control. The aerated static pile composting method, when managed properly, can be a very effective method of composting. During the class we emphasize the need to monitor and manage fish carcasses quite closely to avoid odor issues when composting these types of feed stocks. The use of bio-filters is also emphasized as a method of odor management. These can be either in place as a covering in aerated static piles or as a standalone process. Peter Moon has been a core instructor for the class for over 15 years. Jerry Katt has taken the class and continues to participate in the class by providing his insight into proper management of composting fish carcasses. The Compost Operator training class spends a fair amount of time discussing odor management and its importance. If you have any questions about the content of the class or of Peter Moon and Jerry Katt’s ability to properly compost fish carcasses, please don’t hesitate to contact me.
