Explaining the Growth in Municipal Recycling Programs: The Role of Market and Non-Market Factors

The implementation of thousands of municipal recycling programs in the United States has increased recycling’s portion of solid waste from 10% to 30% over the past decade. But the lack of accurate data has spurred a debate over whether the growth in recycling can be attributed to market or nonmarket factors. To address this issue, this article conducts a benefit-cost analysis of a municipal recycling program. Results suggest recycling is costly. So why, then, does it remain popular? This article suggests that local governments could be responding to households that perceive a benefit from recycling services. These benefits are estimated with a contingent valuation survey.

The Costs of Municipal Curbside Recycling and Waste Collection

This paper estimates cost functions for both municipal solid waste collection and disposal services and curbside recycling programs. Cost data are obtained from a national survey of randomly selected municipalities. Results suggest, perhaps unsurprisingly, that both marginal and average costs of recycling systems exceed those of waste collection and disposal systems. Economies of scale are estimated for all observed quantities of waste collection and disposal. Economies of scale for recycling disappear at high levels of recycling - marginal and average cost curves for recycling take on the usual U-shape. Waste and recycling costs are also estimated as functions of factor costs and program attributes.

Municipal Self-Government in the Ukrainian Lands: 14th-16th Centuries

This project considered the development of municipal self-government (particularly the Magdeburg-law type) in Ukraine through the late Middle Ages in the context of central and eastern European history, using a comparative analysis of different forms of self-government. The Magdeburg Law was brought to the lands of old Rus by German colonists in the period of the Galician-Volhynian State (in the late 13th-early 14th centuries). Municipal self-government based on this law in Ukraine was now however an external artificial phenomenon, but rather an intrinsic need that emerged during the historical development of the society. The Magdeburg Law reached Ukraine through Poland and acquired certain features which were different from the form used in German towns, and Ukrainian towns further adapted the Magdeburg model to their own circumstances. It was "purest" in the western part of the region, while further to the east Magdeburg-Law-type municipal government appeared later, was further removed from its original form, and had a weaker influence on the historical development of the towns. The Magdeburg Law came to be a legalisation of a historically determined process of the emergence of an urban estate.

Twelve factors influencing sustainable recycling of municipal solid waste in developing countries

Sustainable management of solid waste is a global concern, as exemplified by the United Nations Millennium Development Goals (MDG) that 191 member states support. The seventh MDG indirectly advocates for municipal solid waste management (MSWM) by aiming to ensure environmental sustainability into countries’ policies and programs and reverse negative environmental impact. Proper MSWM will likely result in relieving poverty, reducing child mortality, improving maternal health, and preventing disease, which are MDG goals one, four, five, and six, respectively (UNMDG, 2005). Solid waste production is increasing worldwide as the global society strives to obtain a decent quality of life. Several means exist in which the amount of solid waste going to a landfill can be reduced, such as incineration with energy production, composting of organic wastes, and material recovery through recycling, which are all considered sustainable methods by which to manage MSW. In the developing world, composting is already a widely-accepted method to reduce waste fated for the landfill, and incineration for energy recovery can be a costly capital investment for most communities. Therefore, this research focuses on recycling as a solution to the municipal solid waste production problem while considering the three dimensions of sustainability environment, society, and economy. First, twenty-three developing country case studies were quantitatively and qualitatively examined for aspects of municipal solid waste management. The municipal solid waste (MSW) generation and recovery rates, as well as the composition were compiled and assessed. The average MSW generation rate was 0.77 kg/person/day, with recovery rates varying from 5 – 40%. The waste streams of nineteen of these case studies consisted of 0 – 70% recyclable material and 17 – 80% organic material. All twenty-three case studies were analyzed qualitatively by identifying any barriers or incentives to recycling, which justified the creation of twelve factors influencing sustainable municipal solid waste management (MSWM) in developing countries. The presence of regulations, enforcement of laws, and use of incentive schemes constitutes the first factor, Government Policy. Cost of MSWM operations, the budget allocated to MSWM by local to national governments, as well as the stability and reliability of funds comprise the Government Finances factor influencing recycling in the third world. Many case studies indicated that understanding features of a waste stream such as the generation and recovery rates and composition is the first measure in determining proper management solutions, which forms the third factor Waste Characterization. The presence and efficiency of waste collection and segregation by scavengers, municipalities, or private contractors was commonly addressed by the case studies, which justified Waste Collection and Segregation as the fourth factor. Having knowledge of MSWM and an understanding of the linkages between human behavior, waste handling, and health/sanitation/environment comprise the Household Education factor. Individuals’ income influencing waste handling behavior (e.g., reuse, recycling, and illegal dumping), presence of waste collection/disposal fees, and willingness to pay by residents were seen as one of the biggest incentives to recycling, which justified them being combined into the Household Economics factor. The MSWM Administration factor was formed following several references to the presence and effectiveness of private and/or public management of waste through collection, recovery, and disposal influencing recycling activity. Although the MSWM Personnel Education factor was only recognized by six of the twenty-two case studies, the lack of trained laborers and skilled professionals in MSWM positions was a barrier to sustainable MSWM in every case but one. The presence and effectiveness of a comprehensive, integrative, long-term MSWM strategy was highly encouraged by every case study that addressed the tenth factor, MSWM Plan. Although seemingly a subset of private MSWM administration, the existence and profitability of market systems relying on recycled-material throughput, involvement of small businesses, middlemen, and large industries/exporters is deserving of the factor Local Recycled-Material Market. Availability and effective use of technology and/or human workforce and the safety considerations of each were recurrent barriers and incentives to recycling to warrant the Technological and Human Resources factor. The Land Availability factor takes into consideration land attributes such as terrain, ownership, and development which can often times dictate MSWM. Understanding the relationships among the twelve factors influencing recycling in developing countries, made apparent the collaborative nature required of sustainable MSWM. Factors requiring the greatest collaborative inputs include waste collection and segregation, MSWM plan, and local recycled-material market. Aligning each factor to the societal, environmental, and economic dimensions of sustainability revealed the motives behind the institutions contributing to each factor. A correlation between stakeholder involvement and sustainability existed, as supported by the fact that the only three factors driven by all three dimensions of sustainability were the same three that required the greatest collaboration with other factors. With increasing urbanization, advocating for improved health for all through the MDG, and changing consumption patterns resulting in increasing and more complex waste streams, the utilization of the collaboration web offered by this research is ever needed in the developing world. Through its use, the institutions associated with each of the twelve factors can achieve a better understanding of the collaboration necessary and beneficial for more sustainable MSWM.

The effect of demand, tank parameters, and pumping stations on energy use in municipal drinking water distribution systems

Two of the indicators of the UN Millennium Development Goals ensuring environmental sustainability are energy use and per capita carbon dioxide emissions. The increasing urbanization and increasing world population may require increased energy use in order to transport enough safe drinking water to communities. In addition, the increase in water use would result in increased energy consumption, thereby resulting in increased green-house gas emissions that promote global climate change. The study of multiple Municipal Drinking Water Distribution Systems (MDWDSs) that relates various MDWDS aspects--system components and properties--to energy use is strongly desirable. The understanding of the relationship between system aspects and energy use aids in energy-efficient design. In this study, components of a MDWDS, and/or the characteristics associated with the component are termed as MDWDS aspects (hereafter--system aspects). There are many aspects of MDWDSs that affect the energy usage. Three system aspects (1) system-wide water demand, (2) storage tank parameters, and (3) pumping stations were analyzed in this study. The study involved seven MDWDSs to understand the relationship between the above-mentioned system aspects in relation with energy use. A MDWDSs model, EPANET 2.0, was utilized to analyze the seven systems. Six of the systems were real and one was a hypothetical system. The study presented here is unique in its statistical approach using seven municipal water distribution systems. The first system aspect studied was system-wide water demand. The analysis involved analyzing seven systems for the variation of water demand and its impact on energy use. To quantify the effects of water use reduction on energy use in a municipal water distribution system, the seven systems were modeled and the energy usage quantified for various amounts of water conservation. It was found that the effect of water conservation on energy use was linear for all seven systems and that all the average values of all the systems' energy use plotted on the same line with a high R 2 value. From this relationship, it can be ascertained that a 20% reduction in water demand results in approximately a 13% savings in energy use for all seven systems analyzed. This figure might hold true for many similar systems that are dominated by pumping and not gravity driven. The second system aspect analyzed was storage tank(s) parameters. Various tank parameters: (1) tank maximum water levels, (2) tank elevation, and (3) tank diameter were considered in this part of the study. MDWDSs use a significant amount of electrical energy for the pumping of water from low elevations (usually a source) to higher ones (usually storage tanks). The use of electrical energy has an effect on pollution emissions and, therefore, potential global climate change as well. Various values of these tank parameters were modeled on seven MDWDSs of various sizes using a network solver and the energy usage recorded. It was found that when averaged over all seven analyzed systems (1) the reduction of maximum tank water level by 50% results in a 2% energy reduction, (2) energy use for a change in tank elevation is system specific, and (2) a reduction of tank diameter of 50% results in approximately a 7% energy savings. The third system aspect analyzed in this study was pumping station parameters. A pumping station consists of one or more pumps. The seven systems were analyzed to understand the effect of the variation of pump horsepower and the number of booster stations on energy use. It was found that adding booster stations could save energy depending upon the system characteristics. For systems with flat topography, a single main pumping station was found to use less energy. In systems with a higher-elevation neighborhood, however, one or more booster pumps with a reduced main pumping station capacity used less energy. The energy savings for the seven systems was dependent on the number of boosters and ranged from 5% to 66% for the analyzed five systems with higher elevation neighborhoods (S3, S4, S5, S6, and S7). No energy savings was realized for the remaining two flat topography systems, S1, and S2. The present study analyzed and established the relationship between various system aspects and energy use in seven MDWDSs. This aids in estimating the amount of energy savings in MDWDSs. This energy savings would ultimately help reduce Greenhouse gases (GHGs) emissions including per capita CO 2 emissions thereby potentially lowering the global climate change effect. This will in turn contribute to meeting the MDG of ensuring environmental sustainability.

Legislative Legacy: Big Changes in Legislative Article of 1972 Constitution -- Jerry Loendorf, Arlyne Reichert & Rich Bechtel “In the Crucible of Change”

The fulcrum upon which were leveraged many of the dramatic progressive changes in Montana that are documented "In the Crucible of Change" series was the lead up to, preparation, writing and adoption of the 1972 Montana Constitution. As Montana citizens exhibited their concern over the dysfunctional state government in MT under its 1889 Constitution, one of the areas that stood out as needing serious change was the Montana Legislature. Meeting for only sixty calendar days every two years, the Legislature regularly tried to carry off the subterfuge of stopping the wall clock at 11:59 PM on the sixtieth day and placing a shroud over it so they could continue to conduct business as if it were still the 60th day. Lawyers hired by the Anaconda Company drafted most bills that legislators wanted to have introduced. Malapportionment, especially in the State Senate where each county had one Senator regardless of their population, created a situation where Petroleum County with 800 residents had one senator while neighboring Yellowstone County with 80,000 people also had one senator -- a 100-1 differential in representation. Reapportionment imposed by rulings of the US Supreme Court in the mid-1960s created great furor in rural Montana to go along with the previous dissatisfaction of the urban centers. Stories of Anaconda Company “thumbs up – thumbs down” control of the votes were prevalent. Committee meeting and votes were done behind closed doors and recorded votes were non-existent except for the nearly meaningless final tally. People were in the dark about the creation of laws that affected their daily lives. It was clear that change in the Legislature had to take the form of change in the Constitution and, because it was not likely that the Legislature would advance Constitutional amendments on the subject, a convention seemed the only remedy. Once that Convention was called and went to work, it became apparent that the Legislative Article provided both opportunity for change and danger that too dramatic a change might sink the whole new document. The activities of the Legislative Committee and the whole Convention when acting upon Legislative issues provides one of the more compelling stories of change. The story of the Legislative Article of the Montana Constitution is discussed in this episode by three major players who were directly involved in the effort: Jerry Loendorf, Arlyne Reichert and Rich Bechtel. Their recollections of the activities surrounding the entire Constitutional Convention and specifically the Legislative Article provide an insider’s perspective of the development of the entire Constitution and the Legislative portion which was of such a high degree of interest to the people of Montana during the important period of progressive change documented “In the Crucible of Change.” Jerry Loendorf, who served as Chair of the Legislative Committee at the 1972 Montana Constitutional Convention, received a BA from Carroll College in 1961 and a JD from the University of Montana Law School in 1964. Upon graduation he served two years as a law clerk for the Montana Supreme Court after which he was for 34 years a partner in the law firm of Harrison, Loendorf & Posten, Duncan. In addition to being a delegate to the Constitutional Convention, Jerry served on the Board of Labor Appeals from 2000 to 2004. He was designated a Montana Special Assistant Attorney General to represent the state in federal court on the challenge to the results of the ratification election of Montana's Constitution in 1972. Jerry served on the Carroll College Board of Directors in the late 1960s and then again as a member of the Board of Trustees of Carroll College from 2001 to 2009. He has served on the Board of Directors of the Rocky Mountain Development Council since 1970 and was on the board of the Helena YMCA from 1981 to 1987. He also served on the board of the Good Samaritan Ministries from 2009 to 2014. On the business side, Jerry was on the Board of Directors of Valley Bank to Helena from 1980 to 2005. He is a member of the American Bar Association, State Bar of Montana, the First Judicial District Bar Association, and the Montana Trial Lawyers Association. Carroll College awarded Jerry the Warren Nelson Award 1994 and the Insignias Award in 2007. At Carroll College, Jerry has funded the following three scholarship endowments: George C and Helen T Loendorf, Gary Turcott, and Fr. William Greytek. Arlyne Reichert, Great Falls Delegate to the Constitutional Convention and former State Legislator, was born in Buffalo, NY in 1926 and attended University of Buffalo in conjunction with Cadet Nurses Training during WWII. She married a Montanan in Great Falls in 1945 and was widowed in 1968. She is mother of five, grandmother of seven, great-grandmother of four. Arlyne was employed by McLaughlin Research Institute in Great Falls for 23 years, serving as Technical Editor of Transplantation Journal in 1967, retiring as Assistant Director in 1989. In addition to being a state legislator (1979 Session) and a delegate to the 1972 Montana Constitutional Convention, she has filled many public roles, including Cascade County Study Commissioner (1974), MT Comprehensive Health Council, US Civil Rights Commission MT Advisory Committee, MT Capitol Restoration Committee, and Great Falls Public Library Trustee. Arlyne has engaged in many non-profit activities including League of Women Voters (State & Local Board Officer – from where her interest in the MT Constitutional change developed), Great Falls Public Radio Association (President & Founder), American Cancer Society (President Great Falls Chapter), Chair of MT Rhodes Scholarship Committee, and Council Member of the National Civic League. She also served a while as a Television Legislative Reporter. Arlyne has been recipient of numerous awards, the National Distinguished Citizens Award from the National Municipal League, two Women of Achievement Awards from Business & Professional Women, the Salute to Women Award by YWCA, Heritage Preservation Award from Cascade County Historical Society and the State of Montana, and the Heroes Award from Humanities Montana. She remains active, serving as Secretary-Treasurer of Preservation Cascade, Inc., and as Board Member of the McLaughlin Research Institute. Her current passion is applied to the preservation/saving of the historic 10th Street Bridge that crosses the Missouri River in Great Falls. Rich Bechtel of Helena was born in Napa, California in 1945 and grew up as an Air Force brat living in such places as Bitberg, Germany, Tripoli, Libya, and Sevilla, Spain. He graduated from Glasgow High School and the University of Montana. Rich was a graduate assistant for noted Montana History professor Professor K. Ross Toole, but dropped out of graduate school to pursue a real life in Montana politics and government. Rich has had a long, varied and colorful career in the public arena. He currently is the Director of the Office of Taxpayer Assistance & Public Outreach for MT’s Department of Revenue. He previously held two positions with the National Wildlife Federation in Washington, DC (Sr. Legislative Representative [1989-91] and Sr. Legislative Representative for Wildlife Policy [2004-2006]). While in Washington DC, he also was Assistant for Senator Lee Metcalf (D-MT), 1974-1976; Federal-State Coordinator for State of Montana, 1976-1989; Director of the Western Governors’ Association Washington Office, 1991-2000; and Director of Federal Affairs for Governor Kitzhaber of Oregon, 2001- 2003. Earlier in Montana Government, between 1971 and 1974, Rich was Research Analyst for MT Blue Ribbon Commission on Postsecondary Education, Legislative Consultant and Bill Drafter for MT Legislative Council, Research Analyst for the MT Constitutional Convention Commission where he provided original research on legislatures, as well as Researcher/Staff for the MT Constitutional Convention Legislative Committee, from where he drafted the various provisions of the Legislative Article and the majority and minority reports on behalf of the Committee members. Rich has represented Montana’s Governor on a trade and cultural mission to Republic of China and participated in US-German Acid Rain Committee sessions in Germany and with European Economic Community environmental officials in Belgium. He is married to Yvonne Seng (Ph.D.) - T’ai Chi apprentice; author and birder.

Revenue Management in Make-To-Order Manufacturing: Case Study of Capacity Control at ThyssenKrupp VDM

While revenue management (RM) is traditionally considered a tool of service operations, RM shows considerable potential for application in manufacturing operations. The typical challenges in make-to-order manufacturing are fixed manufacturing capacities and a great variety in offered products, going along with pronounced fluctuations in demand and profitability. Since Harris and Pinder in the mid-90s, numerous papers have furthered the understanding of RM theory in this environment. Nevertheless, results to be expected from applying the developed methods to a practical industry setting have yet to be reported. To this end, this paper investigates a possible application of RM at ThyssenKrupp VDM, leading to considerable improvements in several areas.

Using Dynamic Programming Decomposition for Revenue Management with Opaque Products

Opaque products enable service providers to hide specific characteristics of their service fulfillment from the customer until after purchase. Prominent examples include internet-based service providers selling airline tickets without defining details, such as departure time or operating airline, until the booking has been made. Owing to the resulting flexibility in resource utilization, the traditional revenue management process needs to be modified. In this paper, we extend dynamic programming decomposition techniques widely used for traditional revenue management to develop an intuitive capacity control approach that allows for the incorporation of opaque products. In a simulation study, we show that the developed approach significantly outperforms other well-known capacity control approaches adapted to the opaque product setting. Based on the approach, we also provide computational examples of how the share of opaque products as well as the degree of opacity can influence the results.
