Mr. Bryan-Brown is a Civil/Environmental Engineer with experience in compost systems design, biosolids management and wastewater treatment design. He is president and founder of Green Mountain Technologies, a leading manufacturer of composting equipment in the U.S. Responsibilities include overall management of the company, product design and prototyping. He is holder of 3 U.S. patents in the field of composting and is the author of numerous papers. In addition to his work with Green Mountain Technologies, he has worked as consultant to the City of New York Department of Sanitation for food waste composting. Previously, he worked on EPA grants to investigate on-site composting systems for organic wastes.
Session Code: 4A
Session Name: Costs and Data
Session Time: Wednesday, January 26, 8:30 AM to 10:00 AM
Presentation Title: Minimizing Energy Inputs for Compost Manufacturing
Presentation Description: The cost of energy inputs in the form or diesel and electricity are significant factors in the overall cost of operating a composting facility. Finding strategies that minimize those inputs will reduce operating expenses as well as emissions of CO2 equivalents. The primary areas of energy use once the feedstocks are delivered to the facility are:
Preprocessing and grinding
Material handling to place on the compost pad
Method of aeration (either forced aeration, windrow turning or static pile)
Energy use for odor control and leachate management
Curing and screening
The presenter will provide typical energy use for each of these steps using manufacturers specifications and operational data. The presenter will review three operational scenarios for estimated energy consumption:
Windrow vs ASP for energy inputs for forced aeration vs turning
Processing in a building with biofiltration vs outside with biocover and leachate collection and treatment
Using a course grind which uses less fuel and provides a more porous mix which in turn requires less energy to aerate but yields less product
The intent of the presentation is to bring more awareness to the equipment selection and facility design to minimize energy use and CO2e emissions. The target audience are facility operators and system designers and regulators concerned with GHG and air pollution emissions from composting operations.
Workshop Time: Monday, January 24, 9:00 AM – 4:30 PM
Workshop Title: Adding Food Waste to your Compost Facility
Workshop Description: This intensive and interactive one-day training will cover the basic concepts, practices and “how to’s” of commercial compost production. The course will provide a broad foundation for novice compost operators, managers and regulators and will refresh veteran composters on the underlying scientific principles. Subjects will include: Basic principles of composting, process insights, facility design and management, feedstock properties, qualities of compost, odor control, major processing methods, and an overview of markets for compost.
