OPEN ACCESS: WM&R COP28 Waste & Climate Virtual Issue

Waste Management & Research (WM&R) is offering a selection of papers published in WM&R covering a range of relevant state of the art developments in emission reductions. They supplement  recent developments with important publications that elaborate on related matters and contribute to making the case for a sound waste management that expressly and substantially supports reduction and control of GHG emissions. We hope that academic researchers and practitioners alike will benefit from this offer. 

 

COP28 Waste & Climate Virtual Issue is offered for a limited period of time free access to papers as fundamental points and to support decision makers on the importance of sound waste management and circular economy practices for controlling humanly-induced climate forcing.

 

The first paper in the line-up,  The impact of landfill management approaches on methane emissions is co-authored by Heijo Scharff, Hun-Yang Soon, Sam Rwabwehare  Taremwa, Dennis Zegers, Bob Dick, Thiago Villas Bôas Zanon, and Jonathan Shamrock.

ABSTRACT: This article reports on how management approaches influence methane emissions from landfills. The project team created various landfill operational scenarios for different regions of the planet with respect to waste composition, organic waste reduction and landfill gas recovery timing. These scenarios were modelled by applying a basic gas generation model according to the United Nations Intergovernmental Panel on Climate Change (IPCC) recommendations. In general, the IPCC’s recommended modelling parameters and default values were used. Based on the modelling undertaken, two options stand out as being the most effective methane mitigation measures in a wide range of conditions throughout the world: (a) early gas recovery and (b) reduction of the amount of biodegradable organic waste accepted in a landfill. It is noted that reduction of organic input to any given landfill can take many years to realize. Moreover, suitable alternative processing or disposal options for the organic waste can be unaffordable for a significant percentage of the planet’s population. Although effective, organic waste reduction cannot therefore be the only landfill methane mitigation measure. Early landfill gas recovery can be very effective by applying basic technologies that can be deployed relatively quickly, and at modest cost. Policymakers and regulators from around the globe can significantly reduce adverse environmental impacts from landfill gas emissions by stimulating both the early capture and flaring and/or energy recovery of landfill gas and programs to reduce the inflow of organic waste into landfills.

Robert DickMeet Co-Author Bob Dick: Bob is a Senior Vice President and the Business Unit Director of SCS Engineer’s Mid-Atlantic operations, stretching from Maine to South Carolina. He is also one of our National Experts on Elevated Temperature Landfills. He has over three decades of experience on civil and environmental engineering projects related to solid waste management, and has performed landfill and landfill gas engineering projects (design, permitting, construction, and operations) in more than 15 states and several foreign countries. He is a licensed Professional Engineer in Virginia and North Carolina, a Board Certified Environmental Engineer (BCEE), and a member of the American Academy of Environmental Engineers and Scientists.

Bob has also directed and completed numerous project assignments related to solid waste planning and facility projects which have involved residential and commercial collection and recycling programs, as well as convenience centers, composting facilities, and material recovery facility design, permitting, construction, and operations consulting. He has authored several publications and made numerous presentations on air quality, solid waste management, landfill engineering and LFG management/control, design/operations, GHG emissions, composting, and regulatory compliance.
