Rich Flammer


Rich began working in the composting industry nearly three decades ago, managing municipal leaf composting facilities for a Rockland County, New York-based company. Beginning as a site technician, taking windrow temperature readings and throwing lime on leachate and anaerobic leaves, he advanced to project manager and had a dozen sites under his management in New York, New Jersey and Connecticut. 

It was this hands-on experience that formed the basis of his composting expertise, and led to him being transferred to the Midwest, and then San Diego, California, to manage high-volume compost facilities and conduct remediation work on sites with capacity and odor issues. Working on and managing composting facilities laid the foundation for his consulting business and formation of Hidden Resources, which has expanded into a skilled team of professional technicians with experience in multidisciplinary resource conversation and management project development, education, vermicomposting, engineering, marketing, data analysis, community-scale composting, and sustainable landscaping and farming. 

When he's not working, which isn't often, Rich enjoys playing pinball, reading, writing, cooking, gardening and brewing beer.
