Client’s Requirements:
Grimm’s Fuel has been composting green waste from the Portland metropolitan area for over 30 years. The facility was using a static pile method, but as volumes grew and neighbors encroached upon the site, odor complaints became a serious operational issue. GMT was hired by Portland Metro in 2018 to perform an odor study and make recommendations on how to upgrade the facility to reduce odor emissions. After proposing the changes to the city, GMT was hired by Grimm’s Fuel to further assist with these modifications.
