FREE LIVE WEBINAR & Q/A – NOW ON-DEMAND IN THE SCS LEARNING CENTER
Landfills, Solid Waste Departments, municipalities, and agencies all work toward achieving waste diversion goals and lowering carbon footprints. Greg McCarron and Vidhya Viswanathan discuss managing tons of food scraps and other organic materials using different compost approaches in our February forum.
Greg and Vidhya answered your questions about these different systems as they covered the technology, best practices, permitting, odor management, business planning, and financing for sustainable operations.
Mr. McCarron, PE, is a Vice President of SCS Engineers and our National Expert on Organics Management. He has over 35 years of progressively responsible experience in solid waste management, including composting, solid waste planning, waste-to-energy systems, landfill design, and landfill gas systems. His expertise is in designing, permitting, constructing, and operating compost systems and facilities for public and private clients.
Ms. Viswanathan, PE, is a Vice President with over 15 years of experience in solid waste engineering and infrastructure design projects. She is the Director of Engineering of our Southwest Region, where she leads our solid waste engineering operations. Her comprehensive experience includes preparing feasibility studies and the permitting, design, construction, and CQA of composting operations, landfill gas systems, and liquids management.
This educational, non-commercial webinar with a Q&A forum throughout is free and open to all who want to learn more about composting. We recommend this month’s discussion for solid waste operators and facility supervisors, landfill owners, environmental engineers, agency staff, and municipal personnel interested in finding sustainable options for managing organic materials.
Organic materials management is of high interest in our industry. This interest is being driven by state and city regulations and other government policies for diversion of organics from disposal facilities. Five states have food waste disposal bans, including Massachusetts, California, Vermont, Connecticut and Rhode Island, which are in various stages of implementation. Some cities have food waste disposal bans, including San Francisco, Seattle, Portland (Oregon), and Austin. Many states and government agencies have organic diversion policies and goals; e.g., USEPA has a 50 percent reduction goal for food waste sent to landfills, nationwide, by 2030.
SCS is helping public and private entities evaluate their organic waste streams and the applicability of established and emerging technologies (e.g., composting, anaerobic digestion) to their specific communities and circumstances. Current and recent project examples include the following:
SCS is actively pursuing work in the organics materials management sector and has a staff devoted to staying current with the latest trends and technologies. SCS can evaluate, design, permit, construct and operate organics facilities, using varying technologies. Compost technologies that SCS is considering for implementation include:
Anaerobic digestion (AD) technologies that SCS is considering for implementation include high solids (dry) or low solids (wet) systems. High solids/dry systems are applicable for food and yard waste. Dry systems for food and yard waste generally use tunnels, which are gas-tight, concrete, garage-like chambers and are loaded using front-end loaders. Low solids/wet systems are applicable for manure, sludges, and liquid industrial waste. Wet systems generally use vessels, which are mixed and are fed using pumps.
