Mr. Kelley has over 25 years of engineering design experience both as a consultant and in the private sector. In recent years, having led multiple waste characterization studies and developed a training program for the US EPA, he has become GBB’s subject matter expert on waste composition studies.

As part of his background for equipment manufacturers, he has worked on the concept and design of a multitude of processing systems for Municipal Solid Waste (MSW), single stream, construction waste and demolition debris (C&D), biomass, and waste-to-energy projects. He is the concept designer of two facilities, one for single stream processing and one for C&D processing, that were presented Gold Excellence Awards by the Solid Waste Association of North America (SWANA) recognizing outstanding solid waste facilities that demonstrate the highest practices through their commitment to using effective technologies and processes in system design and operations.

Prior to joining GBB, he was Sales Design Engineer at Bulk Handling Systems, a firm that designs, engineers, manufactures, and installs sorting and handling systems throughout the world for the recycling, solid waste, demolition, and power generation industries. Previously, he was Senior Mechanical Engineer at West Salem Machinery, Inc., a manufacturer of grinding, screening, and conveying equipment for the biomass and lumber industry. Before that, he was Mechanical Drafter and Project Engineer for various manufacturers of machinery, where he designed a range of high-end automated equipment.
