This week the solid waste industry is celebrating 25 years of valuable research, inspiration, and support of solid waste professionals provided by the Environmental Research & Education Foundation. On Tuesday, industry leaders met to recognize EREF’s impact on the solid waste industry and acknowledge the role stakeholders play supporting the Foundation and sharing the resulting research.
EREF is a trusted source of data-driven, empirical science for the betterment of solid waste management and policy informing industry, federal and state agencies, academics, and the public. The foundation is also a resource for students and young professionals in the solid waste industry, by providing scholarships, internships, and MSW eTextbook programs. These programs inspire young professionals and ultimately add to EREF’s research and the industry as a whole.
EREF receives funding and participation from companies such as SCS Engineers to continue new research and scholarship programs such as the Robert P. Stearns Master’s Scholarship. The foundation is remarkably successful in producing unbiased reports, which translate ideas and data into action for sustainable waste management practices.
Thank you and congratulations from your colleagues at SCS Engineers for 25 years of scientific research and educational initiatives for the benefit of our industry and the communities we serve.

The Solid Waste Association of North America (SWANA) Applied Research Foundation released a report concluding that: a significant amount of additional food waste processing capacity will be required to achieve national, state, provincial, and local food waste diversion goals. The report also emphasizes the need for local decision-making in selecting and implementing those food waste diversion programs.
…a significant amount of additional food waste processing capacity will be required to achieve national, state, provincial, and local food waste diversion goals. The report also emphasizes the need for local decision-making in selecting and implementing those food waste diversion programs.
The report goes on to say that interest in recovering food waste from municipal solid waste is growing to meet goals established by the U.S. Environmental Protection Agency and U.S. Department of Agriculture, but many major metropolitan areas lack the infrastructure to manage the ability to meet the established goals. Two examples were cited:
Several states, including Massachusetts and Connecticut, condition their food waste diversion requirements on the ability of generators to access adequate capacity within a certain distance.
Speaking as SWANA’s Executive Director and CEO David Biderman stated:
We believe that Americans need to rethink how food is handled before it is considered waste, to divert it into programs to feed people, and to find other productive uses for food as food. Once it becomes waste, however, municipal decision-makers, working with their processing partners, need to determine how to best manage the material.
The SWANA report focuses on the effects of food recovery at the two lowest tiers of the hierarchy – composting and landfilling/incineration. The report concludes that food waste diverted from landfill operations has the potential to be processed at composting facilities. Then, going on to say that anaerobic digestion (AD) and co-digestion at wastewater treatment facilities are also likely destinations for diverted food waste.
Jeremy O’Brien, Director of the Applied Research Foundation, noted:
The food recovery hierarchy does not apply universally; an analysis of greenhouse gas impacts based on local data and conditions is needed to identify the best food scraps management options for a specific community.
The report encourages solid waste managers to perform a life cycle analysis of economic and environmental costs and benefits based on local needs, system capabilities, and data to identify the most effective ways to manage food waste at the local level.
SCS Engineers and SWANA are both long-time advocates for local decision-making in establishing programs to collect and manage municipal solid waste.
Infrastructure Week (May 16–23) is a national week of events, media coverage, education, and advocacy efforts to bring the state of the nation’s infrastructure to the attention of all Americans. Forester Media, the publisher of MSW Management magazine, is an Infrastructure Week affiliate. John Trotti, MSW Managing Editor recently surveyed Jim Walsh, P.E., BCEE, President and CEO of SCS Engineers and long-time friend of the magazine on the topic. Jim is first out of the blocks to answer the four questions John asked of respondents from MSW and Forester’s other publications, Business Energy, Erosion Control, Grading & Excavation Contractor, Stormwater, and Water Efficiency.
MSW Management (MSW): Which infrastructure projects should be given priority? Roads and bridges? Dams and levees? Water supply? Electrical grid? Waste management?
James Walsh (JW): Typically public safety, cost, and benefit determine the priority for infrastructure projects, and different political jurisdictions have different priorities. Where highways and bridges are new but waste management facilities are old, the priority might be waste management facilities, and vice-versa. Some types of infrastructure are more amenable to private sector solutions, which can allow the government to focus on other types of infrastructure. The trend in waste management, for example, has been to rely on the private sector in the last decade
Each segment faces difficult challenges; the most significant is funding. Waste management does not necessarily have priority over other projects, but has progressed by regionally identifying the infrastructure necessary. Thus, each region avoids the pitfalls of competing for funding with other regions and other projects.
SCS Engineers focuses on waste management, but there are opportunities to interact with other segments in sustainable ways. For instance, we have energy clients who supply coal ash to specialty cement companies who use it to make “green” cements that last longer in applications such as road construction. We design and construct facilities that take the byproduct gases from the decomposition in landfills to generate electricity reducing their dependence on fossil fuels, or directly use the gas for energy to power wastewater plants simultaneously cleaning and conserving water. We find ways to safely redevelop contaminated property supported by existing infrastructure, thus reducing the need to build new infrastructure.
In short, we work toward helping clients find sustainable solutions to infrastructure projects.
MSW: Is there a solution to long-term infrastructure funding?
JW: With respect to the waste management infrastructure, waste systems require significant capital investment in land, equipment, facilities, and infrastructure. While many governments have decided to rely on private industry instead of financing new governmental facilities, others have become much more sophisticated in adopting private sector approaches to financing. Pro-Forma Economic Life-Cycle Models can assist governmental entities to identify the critical variables that can impact the success of an infrastructure project. Moreover, economic models evaluate how various components of a waste system and variable assumptions integrate together into a sensible approach. Pro Forma Economic Models allow for a careful analysis of the life-cycle costs and potential revenue sources and identify factors that will influence the waste system costs and demonstrate how to adequately and equitably fund the system. These Models provide different scenarios and eliminate options that are not financially feasible or do not fit a region’s short- and long-term needs or priorities. Sensitivity analysis can be conducted to understand better the impact these variables have on capital costs, operating expense, and the overall system economics. By assessing the economic and regional benefits first, we can focus on designing and building infrastructure solutions that are safer, longer lasting, and affordable. Other benefits include adjusting the Model if there is a major change in the commodity market, such as plastics’ recycling is experiencing now and when considering the use of new technologies.
Every industry segment and every region have a different blend of socio-political conditions, geography, and monetary resources—we assess and design to their particular needs. Adopting new waste management technologies, such as anaerobic digestion or waste diversion, as part of an overall waste management program can be integrated into the Model to study how, and if, they sensibly integrate within the existing program. New technologies are typically more expensive than mature technologies such as recycling facilities and landfills, but that condition alone is not why they are considered valuable to a region. The framework considers elements key to integrating anaerobic digestion for example into a long-term program. Capital investment, a significant centralized source of high-quality organic waste, power costs and economic utility incentives, limited land suitable for composting, lack of conventional waste-to-energy facilities, or a ban on organics disposal in landfills are some of the considerations.
Many states are developing organics diversion initiatives, discouraging or banning organics from landfills; they will want to develop separate capacity for diversion within their overall program to build a sustainable plan for the long-term. In some states there is plenty of environmentally sound landfill capacity, recycling facilities have adequate capacity, and the socio-political climate has different ideals. What works in Iowa might not be suitable for California.
MSW: What kind of harm is the current state of our infrastructure doing to the economy and the community?
JW: Every four years, the American Society of Civil Engineers releases a “Report Card for America’s Infrastructure” depicting our nation’s infrastructure condition and performance. In a traditional school report card format, individual infrastructure segments are assigned letter grades—solid waste has the highest grade of B- in the most recent report published in 2013. The waste management infrastructure in the United States is robust, diverse, and significantly supports our economy and communities by providing safe and cost-effective management of the materials that we discard on a daily basis.
MSW: What can various government entities—from local to Federal—do to attract private sector support and investment?
JW: In the United States, private solid waste facilities manage 75% of the municipal wastestream. The waste management industry has many examples of public/private partnerships and significant investment by the private sector. Just look at firms like Waste Management Inc., Republic Services Inc., Waste Industries, Waste Connections, WCA Waste Corporation, Covanta, and Wheelabrator, which own and operate numerous landfills, compost facilities, waste-to-energy facilities, transfer stations, processing facilities, alternative technologies, and hauling companies. These facilities require significant private investment. Allowing private industry to participate in the management of waste management infrastructure brings needed fiscal discipline and accountability to the overall waste system infrastructure.
The private sector is attracted to markets that are predictable and that provide an appropriate return on investment. Jurisdictions with a reputation for making sudden unpredicted changes in regulations that adversely affect the return on investment will find it difficult or impossible to attract private sector support.
The waste management sector and SCS Engineers have seen our share of magic technologies that are literally too-good-to-be-true, yet somehow attract governmental support both financial and otherwise. It is fine for government agencies to provide grant support for research related to promising new technologies, but adopting an unproven technology as the sole means of waste management is inviting a public health crisis. Private sector investment is not attracted to jurisdictions that have unrealistic expectations.

SCS Engineers along with Waste Management, Republic Services, Advanced Disposal, National Waste & Recycling Association, Solid Waste Association of North America, The Sanitation Districts of the County of Los Angeles, and other consultants have submitted additional comments to the U.S. Environmental Protection Agency (USEPA), Fuels & Incineration Group, Sector Policies and Programs Division regarding the Supplemental Proposal for the New Standards of Performance (NSPS) for Municipal Solid Waste (MSW) Landfills and the Proposed Emission Guidelines (EG).
The USEPA solicits comments from industry, state officials and other organizations to clarify key points in proposed policy prior to enacting the policy. Although the Agency is not required to consider additional comments after the closing period for such comments, these solid waste industry participants wanted to provide additional findings supporting portions of the policies and guidelines and asking for clarification in areas where there appears to be inconsistency with other federal rules or a lack of data.
The eighteen-page letter was submitted on January 22, 2016, to Ms. Hillary Ward. Since last Friday inclement weather has forced a closing of Federal Agencies in the Washington, D.C. region.

John F. Hartwell, Ph.D., PE., CHMM, and Senior Consultant at SCS Engineers recently successfully defended his dissertation and earned his Ph.D. An abstract of Dr. Hartwell’s dissertation follows:
METHODOLOGY FOR ASSESSING MUNICIPAL SOLID WASTE USING A LARGE-DIAMETER BOREHOLE
LTC John F. Hartwell, Ph.D., P.E.
University of Nebraska, 2015
Municipal solid waste (MSW) landfills are permanent repositories of society’s non-hazardous wastes. Landfill facilities are becoming harder to site, resulting in increasing pressure to maximize the use of available airspace. Increasingly, this results in developing additional airspace by way of vertical expansion. This expansion imparts greater stress on the landfill mass and the containment infrastructure.
The engineer’s understanding of the geotechnical properties of MSW has been limited to sampling of relatively shallow test pits and reconstitution of disturbed MSW samples in the laboratory. Deeper assessment using small diameter borings is difficult and produces poor low volume samples for ex-situ testing. Some researchers have synthesized MSW with obvious limitations. Landfill failures have provided opportunities for back calculation of MSW properties including shear strength, but these estimates are based on limited understanding of unit weight and moisture content with depth.
The recent trend for the harvesting of methane produced by the anaerobic degradation of MSW has resulted in the need for nearly full-depth, large-diameter, landfill gas collection wells. Prior to completion, these boreholes provide excellent opportunities for directly observing and measuring the condition of MSW in its buried, variably degraded state at depths that are far greater than previously accessible.
The large diameter MSW gas well borehole assessment methodology presented in this paper is shown to be an efficient and valuable means for characterizing MSW. This means that the cost of the assessment is relatively low as the drilling costs are negligible and therefore limited to the cost of labor to sample and perform field observation and laboratory testing. The assessment methodology, which includes scaled full coverage photography and videography, allows precise analysis of a number of geotechnical properties such as wet and dry unit weight, moisture content, specific gravity, void ratio, % saturation of MSW and buried soil layers throughout the depth of the borehole. Further, MSW constituents and biologic degradation can be measured. The orientation / alignment of tensile reinforcement within the waste mass is readily observable. Zones of perched leachate and the effects of mechanical creep on borehole diameter can also be measured.

SCS Engineers and their clients appreciate the support. The National Waste & Recycling Association (NWRA) and the Solid Waste Association of North America (SWANA) sent the Environmental Protection Agency (EPA) supportive comments on the proposed revisions to the Research, Development and Demonstration (RD&D) Permits Rule for Municipal Solid Waste Landfills (80 FR70180, November 13, 2015).
EPA’s proposed extension to the RD&D Rule would afford landfill owners the opportunity to continue to operate and develop new data and information that would influence future decision-making by regulators and industry alike. The time extension will provide additional time to help landfill owners evaluate and realize the financial value of the RD&D projects, thus increasing landfill owners’ confidence in implementing related large scale projects. These investments would be for the design, construction, additional monitoring and data collection and reporting that accompany long-term research projects, such as those associated with bioreactor landfills.
The RD&D rule provides the ability to obtain data on best practices to address both the advantages and challenges associated with bioreactor landfills. Operating these types of landfills have many advantages, they are not without their challenges. A bioreactor landfill is much more complex than a typical landfill.
NWRA, SWANA, and SCS Engineers believe this proposed rule will promote new research demonstration projects and support the continued research at existing projects so that EPA will have the information necessary to consider changes to the MSW landfill operating criteria.
