Background/Objective: Waste management poses a notable environmental hurdle for developing countries, chiefly revolving around the collection and disposal practices varied across societies. This study aims to investigate the determinants of knowledge, attitude, and practices of refuse disposal methods among residents of Port Harcourt.Methods: A cross-sectional survey involving 422 adult residents of Port Harcourt Metropolis was conducted. Participants completed a questionnaire assessing their knowledge, attitude, and practices regarding refuse disposal methods. Statistical analysis, including descriptive and correlation analysis, were employed to assess levels of knowledge, attitude, practices, and factors influencing refuse disposal, as well as the relationships between these variables.Results: Findings indicate a high level of knowledge (85%), positive attitude (81%), and moderate practices (63%) regarding refuse disposal methods among residents of Port Harcourt Metropolis. Factors influencing refuse disposal in the area include access to waste disposal facilities (88%), cost of waste disposal (55%), peer influence (23%), lack of awareness (48%), and government policies (72%). Chi-Square test indicates a significant relationship between knowledge and practice, as well as attitude and practice of refuse disposal methods among residents of Port Harcourt, at the significance level (p < 0.05).Conclusion: The research indicates that Port Harcourt residents generally possess a high level of knowledge and a positive attitude towards refuse disposal, coupled with moderate practices. Nevertheless, significant factors such as access to waste disposal facilities and governmental policies influence these practices, highlighting the necessity for focused interventions and policy improvements to enhance waste management efforts in the region.

Growing environmental pressures and escalating intake water costs are causing an increasing number of industrialists to reappraise their effluent treatment facilities with a view to effluent recycle and/or resource recovery. In certain instances industrialists have opted for treated sewage effluent as a water source for their process. Water Management Schemes are being, or have been, implemented at a number of industrial concerns in order to rationalise overall water intake and effluent disposal costs.

Full textAbstract:
Solid Refuse Fuel (SRF) manufacturing facilities process 4.72 million tons of waste annually. The residues generated after manufacturing SRF products account for 35–40% of the input waste, and most of them are finally disposed of in landfills. The process flow and management status of SRF manufacturing facilities were investigated, and the residues generated from SRF manufacturing facilities using municipaland industrial waste, respectively, were separated by particle size. The appropriate separation conditions for the residues according to the characteristics of the input raw materials were presented through the analysis of loss on ignition (LOI), organic foreign substance content, heating value, and carbon content. Based on this, the appropriate management criteria (draft) for the subsequent treatment of final residues were derived to improve recyclability. Residues generated in the SRF manufacturing process need to be additionally separated into combustibles and incombustibles through cylindrical rotary separating devices before subsequent the final disposal process.

Full textAbstract:
Legal regulations on waste disposal require waste producers to limit landfilling and to find different ways of waste management, the preferred methods being recycling of material and energy potential. Currently, in Poland, the only consumers of refuse-derived fuels (RDF) are cement plants. However, their ability to utilize alternative fuel is far from the estimated potential. One solution would be to redirect the excess fuel to power and heat production facilities. Unfortunately, these sectors are facing a number of problems related to the thermal treatment of waste, mainly formal nature. Co-combustion of waste in power plants raises a lot of concern among their employees and local communities. Especially significant is the harmfulness of usage of fuel from waste for the people’s lives or health, or the environment. The article compares the environmental footprints of the combustion process of: waste - based fuel (RDF) and lignite. The analysis was performed for a standard pulverized coal fired boiler. Comparative assessment was made by analyzing the total environmental impact of all combustion products of the two fuels. Final results have shown, that the environmental footprint of waste-based fuels can be similar or even smaller than traditional coal-based fuels

In recent years, managing solid waste has become one of Nigeria’s biggest problems, especially in metropolitan and semi-urban areas. The problem of waste generation, handling and disposal has reached a disturbing level in Nigerian urban centers. The study analyzed solid waste management practices in Jalingo, Taraba State, Nigeria. These were achieved through characterizing the types of solid wastes generated and ascertain the solid waste storage facilities of the study area. The majority of the information used in this study came from the distribution of a questionnaire, with additional information coming from oral interviews, direct field observations, and photographs of the subject area. Tables of frequencies and percentages were used to provide answers to the study questions. Tests of the relationship’s Pearson product moment correlation coefficient were conducted. The findings demonstrated that the majority of the solid waste generated in the study area was organic waste (53%). The storage facilities in the study area were dustbins, poly bags, refuse carts, and nearby refuse heaps. The Pearson product moment correlation coefficient analysis showed strong and significant differences between the solid wastes generated and sold waste storage facilities in the study area, with an alpha value of 0.05. The findings of this study showed that the characteristics of the solid waste generated are not in line with the storage facilities. This implies that not much attention has been given to solid waste management in the study area. The study also recommends public awareness to promote waste management practices; more government approved waste collection centers, awareness campaign on waste reduce, reuse, recycle and waste separation method in the study area.

The activity of sewage treatment plants for the treatment of domestic wastewater is not limited only to wastewater treatment. The main problem in this activity is the treatment and disposal of the resulting sediments at sewage treatment plants, where the main task is to reduce the volume of sediment and then transform it into a useful product that does not cause environmental pollution. Currently, representatives of landfills refuse to accept this type of precipitation, explaining that this type of precipitation does not belong to the category of solid municipal waste. The issue of using sediments from sewage treatment plants as raw materials for manufacturing remains open, but in our opinion this type of sediment can be recycled in wastewater treatment technology. The practical value lies in conducting industrial tests of the converter of sewage sludge into liquid effluents, including all waste generated during the operation of sewage treatment plants with subsequent post-treatment of liquid effluents at wastewater treatment plants. These tests will reduce the amount of sediment by up to 90%, which will minimize the intensive accumulation of precipitation from sewage treatment plants and improve the state of the environment.

Full textAbstract:
Thermochemical conversion of raw municipal solid waste (MSW) is continuously growing in the context of contemporary technology. The quality of MSW needs an improved analysis to enhance the choice of energy exploitation and environmental assessment of fly and bottom ashes associated with thermochemical conversion. MSW was collected from solid waste disposal facilities (SWDF) in Cape Town in order to investigate heavy metal distributions in MSW obtained from SWDF. The MSW was pre-treated to improve its quality. The 7700 Series quadrupole ICP-MS solution method was used to determine the concentrations and distributions of some heavy metals from SWDF in Cape Town. This study assessed and quantified the distributions of heavy metal in MSW in the city of Cape Town. The accumulation of high concentrations of heavy metals in bottom ash residue from thermochemical conversion could be a good remedy for heavy metals control. High transfer coefficients of heavy metals were observed, and the heavy metals were mainly transferred to the bottom ash. Heavy metals such as Cd, Cu, Pb, and Zn in bottom ash are regarded as relatively unstable with the highest concentrations of Cu and Zn 1295 mg/Kg and 3347 mg/Kg, respectively. The heavy metals (especially Pb, Zn and Hg) emissions were technically monitored and controlled from escaping into the urban air-sheds atmosphere and prevented from their consequential secondary environmental and health implications.

The aim of the study is to assess faecal sludge management (FSM) in Nguru town, Nguru Local Government area of Yobe State. Random sampling method was used in the selection of respondents in six political wards of the study area. A total of 399 questionnaires were administered to respondents in the study area with the view to identify the types and current practices of faecal sludge management in the study area. The result of the study indicates that majority of the respondents 68% used pit latrine, 24% used water closet while 8% used other type of toilet facilities. However, on the excreta defecation, the finding indicated that 84% had access to household toilets, 8.0% used public toilets, and 6.0% practiced open defecation with the remaining 2% practicing defecation in polythene bags after which they discard it into the bush or on a refuse dump. The study further revealed that majority (54%) of the respondents disposed their toilet sludge by land fill, 31% participants were using any available land for faecal sludge final disposal while 10 % and 5% disposed their toilet by nearby river and composting respectively. The finding indicated that, the faecal sludge management of the study area is unsatisfactory and may pose a risk of environmental and adverse human health. The current practices of faecal sludge management were found below international standard requirement set by WHO. It is therefore recommend that Government should come up with proper orientation and environmental laws should be put in place for the general public and also to provide necessary facilities and arrange for better methods of faecal sludge management.

Improper sewage and solid waste disposal lead to environmental pollution and increased risk of communicable diseases. This study compared the sanitation and solid waste disposal facilities utilized in selected rural and urban local government areas of Anambra State, Nigeria. This cross-sectional study was conducted among 1310 households and data was collected from household heads or a designated adult representative using of quantitative (questionnaire) and qualitative (KII) data collection methods. The independent variables in this study are the sociodemographic variables and the geographical location of the respondents while the dependent variables are the toilet facilities and solid waste disposal methods. Data from the questionnaire was analyzed using the SPSS version 23 and the hypotheses were tested with the inferential statistics of Chi square at 0.05 level of significance. Most respondents lie between the age group of 31-50 years. Most of the respondents in both the urban (84.4%) and rural(65.0%) areas had secondary education and above but a higher proportion in the urban compared to rural have tertiary education(41.9% versus 22.1%). The difference in educational status was statistically significant (p = 0.0001). There were more business men (46.6%) and civil servants (38.8%) in the urban area than the rural area. Most rural respondents were farmers(41.5%). Many urban household use toilet with sewer connection 152(11.7%) while pit latrine with slab is the most commonly used toilet facility 242 (18.6%). Burning was more commonly used by the rural households (n = 266, 20.5%). Open dumping of refuse and disposal into gullies and water ways were commonly done by the urban households. The gaps that exist between rural and urban areas of Anambra state may present serious health risk and environmental degradation .This issues can be addressed through health education, building more sanitary infrastructure to include the rural areas and enforcing sanitation laws.

Full textAbstract:
The siting of municipal solid waste disposal facilities is often unsuccessful or delayed because of host community opposition. Physical, economic, social and political impacts of landfill and an incinerator site are identified, assessed and combined in a rational model to explain the cause of opposition.
Residents' beliefs about facility impacts correspond well with the assessed physical impacts at the landfill in identifying odor, birds, traffic, water emissions and explosion risks as negative impacts and convenient disposal as a benefit. At the incinerator, common resident beliefs comprise odors, noise, traffic and air emissions as negative impacts and energy recovery as a benefit. Underlying these obvious physical impacts, however is a group of non-physical beliefs about the harm to community image, loss of control, unfairness, and property value losses in the host community. These non-physical impacts influence the attitude about the facility as strongly as the physical impacts.
Finally, exposure to obvious physical impacts is shown to negatively influence the beliefs about physical and non-physical (economic, social and political) impacts. Thus, by screening the host community from obvious physical impacts (nuisances), the beliefs about community image, control, fairness and property values can be enhanced.
Since negative attitude and opposition action are strongest prior to facility construction, the siting efforts need to be focused on this period. After construction, the host community adapts to the new situation.
The facility impacts are combined into a model to define a criterion for acceptance. The net value of facility impacts and benefits must reach or exceed in value the narrow tolerance range at the original host community reference point to avoid significant host community opposition. Impact reduction rather than compensation is theoretically shown to be the more effective approach to fulfilling the acceptance criterion. This approach is empirically tested at typical waste facility sites.
Despite higher costs for prevention and emission control methods to reduce physical and non-physical impacts, these methods are shown to be superior to mitigation and compensation in gaining community acceptance.
Based on the conclusions, the policy statement on waste facility sitings recommends first, defining entitlements and rules for the siting process, establishing increasing waste reduction and separation in a waste management plan, and using participative community planning as long-term, preventive facility siting measures. Short term siting measures comprise, the negotiation of siting agreements, the use of best available technical emission controls and continued monitoring by an overview committee. The focused use of prevention and control measures to address host community concerns can substantially enhance community acceptance of municipal solid waste facilities.Applied Science, Faculty of

Submitted in fulfillment of the requirements for the Master of Information and Communications Technology, Durban University of Technology, Durban, South Africa, 2017.The future of modern cities largely depends on how well they can tackle intrinsic problems that confront them by embracing the next era of digital revolution. A vital element of such revolution is the creation of smart cities and associated technology infrastructures. Smart city is an emerging phenomenon that involves the deployment of information communication technology wares into public or private infrastructure to provide intelligent data gathering and analysis. Key areas that have been considered for smart city initiatives include monitoring of weather, energy consumption, environmental conditions, water usage and host of others. To align with the smart city revolution in the area of environmental cleanliness, this study involves the development of a web based smart city infrastructure for refuse disposal management using the design science research approach. The Jalali smart city reference architecture provided a template to develop the proposed architecture in this study. The proposed architecture contains four layers, which are signal sensing and processing, network, intelligent user application and Internet of Things (IoT) web application layers. A proof of concept prototype was designed and implemented based on the proposed architecture. The signal sensing and processing layer was implemented to produce a smart refuse bin, which is a bin that contains the Arduino microcontroller board, Wi-Fi transceiver, proximity sensor, gas sensor, temperature sensor and other relevant electronic components. The network layer provides interconnectivity among the layers via the internet. The intelligent user application layer was realized with non browser client application, statistical feature extraction and pattern classifiers. Whereas the IoT web application layer was realised with ThingSpeak, which is an online web application for IoT based projects. The sensors in the smart refuse bin, generates multivariate dataset that corresponds to the status of refuse in the bin. Training and testing features were extracted from the dataset using first order statistical feature extraction method. Afterward, Multilayer Perceptron Artificial Neural Network (MLP-ANN) and support vector machine were trained and compared experimentally. The MLP-ANN gave the overall best accuracy of 98.0%, and the least mean square error of 0.0036. The ThingSpeak web application connects seamlessly at all times via the internet to receive data from the smart refuse bin. Refuse disposal management agents can therefore query ThingSpeak for refuse status data via the non browser client application. The client application, then uses the trained MLP-ANN to appositely classify such data in order to determine the status of the bin.

INTRODUCTION All waste generated at health care facilities in the past was regarded as hazardous and needed to be incinerated first before it was disposed. The purpose of this study was to investigate health care waste (HCW) management practices employed in public health clinics in the iLembe District, with a view of developing a HCW management intervention strategy. METHODOLOGY The study design was observational, descriptive, and cross-sectional. Data was collected using a structured individual questionnaire, which was administered to key informants from 31 rural and urban government fixed public clinics in the iLembe District Municipality. RESULT Thirty public clinics in iLembe district participated in the study. A total of 210 kg/day (0.06 kg/patient/day) of HCW was estimated to be generated in public clinics, 69% was health care general waste (HCGW) and 31 % was health care risk waste (HCRW). The district's generation rate was 0.04 kg/patient/day and 0.018 kg/patient/day, for HCGW and HCRW, respectively. The study found that HCW was improperly managed in the district. DISCUSSION The findings are different when compared to World Health Organisation norms and this was attributed to improper segregation of waste categories other than sharp waste, which was given special treatment. Factors such as the number of patients, size of the clinic, types of health care services rendered, and socio-economics status of the patient played a pivotal role in the waste volume generated. It is evident that no proper HCW management plan was being implemented in the district public clinics. CONCLUSION The management of health care risk waste is of great concern. There is a need for development of a health care waste management intervention strategy that must be implemented consistently and universally in the district. RECOMMENDATIONS It is recommended that a proper health care waste management intervention strategy be developed and implemented in the whole district. This strategy must incorporate training programmes and a waste management plan.Thesis (MPH)-University of KwaZulu-Natal, 2007.

Full textAbstract:
In response to government and public pressures, the healthcare industry has in the past few years directed a significant effort toward the proper and safe management of its medical waste streams. Medical waste is classified as a biohazardous waste, which according to a study published by the United States Agency for Toxic Substances and Disease Registry (1990), may result in human infection and transfer of disease. This includes injury and infection with the Hepatitis B Virus (HVB) and the Human Immunodeficiency Virus (HIV), by janitorial and laundry workers, nurses, emergency medical personnel, and refuse workers who may come into contact with medical waste. In a recent survey conducted in the United States and Japan, and reported by the World Heath Organization (WHO) (1994), it was found that injuries by sharps constitute about 1% to 2% per annum for nurses and maintenance workers and 18% per annum for outside waste management workers. In Japan, the survey indicated that injuries by sharps constitute about 67% for in-hospital waste handlers and 44% for outside waste management workers. In order to reduce the risks associated with medical waste, proper management mechanisms should be adopted by healthcare facilities to protect the health of the staff within the medical facility, waste collectors/workers, and the public once the waste has left the facility for final disposal. These mechanisms include waste identification, segregation, storage, and treatment. However, and as a first step in the implementation of a waste management system, the management of a medical facility should conduct an audit of the generated waste streams.

The Authority has proactively planned and implemented its current integrated solid waste management program to ensure disposal capacity through 2021. However, even in consideration of the current economic climate, the Authority anticipates continued population growth and associated new development patterns that will significantly increase demands on its solid waste system, requiring it to reevaluate and update its planning to accommodate future growth. The NCRRF, the Authority’s refuse derived fuel waste-to-energy facility, has performed very well since its start up in 1989 processing over 13 million tons of MSW, saving valuable landfill space and efficiently producing clean renewable energy. As the NCRRF has reached the end of its first 20 year operating term, it became necessary to complete a comprehensive refurbishment to ensure its continued reliable service for a second 20 year term and beyond providing for continued disposal capacity and energy production for the Authority’s customers. Separately, the Authority also recognized that the refurbishment alone will not provide any additional disposal capacity for the County. The County’s anticipated growth necessitated that the Authority evaluate several options for long-term processing and disposal capacity, resulting in a decision to expand its WTE capacity with a new mass burn facility, the first facility of its kind to be constructed in Florida in more than a decade, reaffirming its commitment to waste-to-energy. The planned 3,000 TPD expansion will provide a total disposal capacity of 5,000 TPD generating approximately 150MW of renewable energy. The decision to proceed with the expansion was approved by the Authority’s Board in October 2008. The Authority, with its Consulting Engineer, Malcolm Pirnie, Inc., has since made significant progress in the facility’s implementation including the completion of the preliminary design, submittal of environmental permit applications, ongoing procurement of a full service vendor, issuance of revenue bonds for project financing, and commencing extensive public outreach. This paper will focus on the development of the new mass burn facility and an update of the status of activities conducted to date including, permitting, financing, vendor procurement, design, and public outreach, as well as will highlight several innovative design, procurement, permitting, and financing features of this landmark project for the Authority, such as: • Utilization of SCR technology for control of NOx emission; • Incorporation of rainwater harvesting and water reuse; • Utilization of iterative procurement process designed to obtain vendor input in a competitive environment; and • Financing approach designed to preserve alternative minimum tax benefits.

Currently, there are 86 communities in the U.S. which employ waste-to-energy (WTE) facilities as a means of high quality solid waste disposal. The WTE process beneficially produces electricity while reducing the volume of landfill waste by up to 90 percent, thereby extending the remaining life of a community’s landfill more than ten-fold. However, the traditional WTE process requires a significant volume of water. This interdependency is often referred to as the “water-energy nexus.” An innovative approach was needed to optimize water conservation for a new 3,000-ton-per-day (TPD) mass burn WTE facility in Palm Beach County (PBREF2). With this in mind, a cascading water management system (CWMS) was developed that uses alternative water supply sources and a cascading hierarchy of water systems that maximize reuse to meet the new facility’s water needs. The selection of an air-cooled condenser to be used for cooling purposes, instead of the wet cooling systems traditionally in place at these facilities will also significantly reduce the amount of water needed in the overall process. The WTE facility will be constructed adjacent to an existing 2,000-TPD refuse-derived fuel facility (PBREF1), allowing beneficial reuse of some of the cooling tower blowdown from the RDF facility as a source of supply water in the new facility. The reuse of this process wastewater will conserve clean water sources that otherwise would have to be used as a source of makeup to the new facility, as well as reduce the amount of wastewater disposed through deep-well injection from the RDF facility. Harvested rainwater and industrial supply well water will also be used as alternative sources of supply to the new facility. The innovative CWMS will maximize reuse and reduce the amount of makeup water needed to the system. As water conservation continues to be of high concern in all areas of the globe, this concept can be applied to other WTE and industrial facilities. This paper will provide an overview of the innovative CWMS that has been designed for the PBREF2 facility.

Abstract Vitrification of the residues from thermal processes into a dense, grainless, amorphous, glasslike material may provide an opportunity to permanently relieve our concerns regarding aquifer contamination and ... if the vitrified products are utilized, conserves those land areas which are suitable for disposal for those discards for which we have not as yet found a practical use. This discussion briefly describes and illustrates the implementation of the $1.2 million ASME/U.S. Bureau of Mines (BuMines) investigative program. The discussion will cover the scope and methods followed, equipment systems employed, and areas of investigation, as well as findings and conclusions in determining the potential effectiveness of sequentially vitrifying significant quantities of ash/residue from (a) three different types of mass burning municipal solid waste energy recovery facilities, (b) a regional wastewater treatment plant sludge combustor, and (c) air quality control products from a large energy recovery facility that burned refuse-derived-fuel while utilizing a fraction of the electric energy recovered. The project also identified potential beneficial applications for the resulting products, the environmental implications and projected overall economics.

Full textAbstract:
In the summer of 2009, Governor John P. DeJongh, Jr. announced that the Virgin Islands Water and Power Authority (WAPA) had just signed two 20-year Power Purchase Agreements, and the Virgin Islands Waste Management Authority (VIWMA) had signed two 20-year Solid Waste Management Services Agreements with affiliates of Denver-based Alpine Energy Group, LLC (AEG) to build, own, and operate two alternative energy facilities that will serve the residents of St. Croix, St. John, and St. Thomas. The alternative energy facilities, to be built on St. Croix and St. Thomas, have a projected cost of $440 million and will convert an estimated 146,000 tons per year of municipal solid waste into refuse-derived fuel (RDF) using WastAway Services® technology, which will be combined with petroleum coke as fuel in fluidized bed combustion facilities to generate steam and electric power. These sustainable projects will provide 33 MW of electric power to St. Thomas and St. John and 16 MW of electric power to St. Croix, and will help to provide long-term cost stability for electric power and solid waste management in the Territory. Construction is expected to start in spring 2010 with an anticipated completion date during the fourth quarter of 2012. This procurement is a significant achievement for the U.S. Virgin Islands. When the projects are fully implemented, they will allow the Territory to reduce its dependence on oil, recover the energy value and certain recyclable materials from its municipal solid waste, and divert this waste from landfill. Since VIWMA has the responsibility to collect and/or dispose of solid waste year-round, having a system incorporating multiple solid waste processing lines and an adequate supply of spare parts on hand at all times is crucial to meeting the daily demands of waste receiving and processing, and RDF production. Also, with the location of the US Virgin Islands in a hurricane zone, and with only one or two combustion units available in each Project, the ability to both stockpile waste pre-RDF processing and store the produced RDF is very important. Gershman, Brickner & Bratton, Inc. (GBB)’s work has included a due diligence review of the Projects and providing professional support in VIWMA’s negotiations with AEG. GBB’s initial primary assignment centered on reviewing the design and operations of the RDF processing systems that will be built and operated under the respective Service Contracts. VIWMA needed to undertake a detailed technical review of the proposed RDF processing system, since this was the integration point of the waste collection system and waste processing/disposal services. GBB, in association with Maguire, was requested to provide this review and present the findings and opinions to VIWMA. In the completion of this effort, which included both a technical review and participation in negotiations to advance the Service Contracts for the Projects, GBB made direct contact with the key equipment suppliers for the Projects proposed by AEG. This included Bouldin Corporation, the primary RDF processing system supplier, with its patented WastAway technology, and Energy Products of Idaho, the main thermal processing equipment supplier, with its fluidized bed combustion technology and air pollution control equipment. Additionally, since the combustion systems for both Projects will generate an ash product that will require marketing for use and/or disposal over the term of the Service Contracts, GBB made contact with LA Ash, one of the potential subcontractors identified by AEG for these ash management services. Due to the nature of the contract guarantees of VIWMA to provide 73,000 tons per year of Acceptable Waste to each Project for processing, VIWMA authorized GBB to perform a current waste stream characterization study. Part of this effort included waste sorts for one week each in February 2009 on St. Croix and March 2009 on St. Thomas, with the results shared with VIWMA and AEG, as compiled. The 2009 GBB waste stream characterization study incorporated historical monthly waste weigh data from both the Bovoni and Anguilla Landfills that were received from VIWMA staff. The study has formed a basis for continuing to augment the waste quantity information from the two landfills with the additional current monthly results compiled by VIWMA staff going forward following the waste sorts. The final GBB report was published in December 2009 and includes actual USVI landfill receipt data through August 31, 2009. The information contained in this document provides the underpinnings to allow for better tracking and analysis of daily, weekly and monthly waste quantities received for recycling, processing and disposal, which are important to the overall waste processing system operations, guarantees and cost projections. GBB’s annual projections are that the total waste on St. Croix is currently over 104,000 tons per year and over 76,000 tons per year on St. Thomas. The thermal processing technology selected for both Projects is a fluidized bed process, employing a heated bed of sand material “fluidized” in a column of air to burn the fuel — RDF and/or Pet Coke. As such, the solid waste to be used in these combustion units must be size-reduced from the myriad of sizes of waste set out at the curb or discharged into the large roll-off boxes or bins at the many drop-off sites in the US Virgin Islands. While traditional RDF would typically have several days of storage life, the characteristics of the pelletized RDF should allow several weeks of storage. This will be important to having a sound and realistic operating plan, given the unique circumstances associated with the climate, waste moisture content, island location, lack of back-up disposal options and downtime associated with the Power Generation Facility. During the negotiations between AEG and VIWMA, in which GBB staff participated, in addition to RDF and pelletized RDF as the waste fuel sources, other potential fuels have been discussed for use in the Projects and are included as “Opportunity Fuels” in the Service Contracts. These Opportunity Fuels include ground woody waste, dried sludges, and shredded tires, for example. Therefore, the flexibility of the EPI fluidized bed combustion boilers to handle multi-fuels is viewed as an asset over the long term, especially for an island location where disposal options are limited and shipping materials onto and off of each island is expensive. This presentation will provide a unique behind-the-scenes review of the process that led to this historic agreement, from the due diligence of the proposed technologies, to implementation planning, to the negotiations with the contractor. Also discussed will be the waste characterization and quantity analysis performed in 2009 and the fast-track procurement planning and procurement of construction and operating services for a new transfer station to be sited on St. Croix.

Full textAbstract:
According to the waste management hierarchy published by the U.S. EPA, waste reduction and reuse are the most preferred modes of waste management, followed by recycling, energy recovery and lastly disposal. As many communities in the U.S. work towards sustainable waste management practices, recycling tends to be a cost-effective and common solution for handling municipal solid waste. With the introduction of single-stream recycling and automated materials recovery facilities (MRFs), where commingled recyclables are sorted into various commodity streams for sale to recycling facilities, recycling rates have steadily climbed in recent years. Despite increasing total recycling rates, contamination and diminishing returns for higher recovery ratios causes MRFs to landfill 5–25% of the incoming recycling stream as residue. This residue stream is composed primarily of plastics and fiber, both of which have high energy content that could be recovered instead of buried in a landfill. Plastics in particular are reported to have heat contents similar to fossil fuels, making energy recovery a viable end-of-life pathway. Sorting, shredding and densifying the residue stream to form solid recovered fuel (SRF) pellets for use as an alternative fuel yields energy recovery, displaced fossil fuels and landfill avoidance, moving more disposed refuse up the waste management hierarchy. Previous studies have shown that plastic, paper, and plastic-paper mixes are well suited for conversion to SRF and combustion for energy production. However, these studies focused on relatively homogenous and predictable material streams. MRF residue is not homogenous and has only a moderate degree of predictability, and thus poses several technical challenges for conversion to SRF and for straightforward energy and emissions analysis. This research seeks to understand the energetic and environmental tradeoffs associated with converting MRF residue into SRF for co-firing in pulverized coal power plants. A technical analysis is presented that compares a residue-to-SRF scenario to a residue-to-landfill scenario to estimate non-obvious energy and emissions tradeoffs associated with this alternative end-of-life scenario for MRF residue. Sensitivity to key assumptions was analyzed by considering facility proximity, landfill gas capture efficiency, conversion ratio of residue to SRF and the mass of residue used. The results of this study indicate that the use of MRF residue derived SRF in coal fired steam-electricity power plants realizes meaningful reductions of emissions, primary energy consumption, coal use and landfill deposition.

The Authority renegotiated and extended its operating agreement with the Palm Beach Resource Recovery Corporation (PBRRC), a Babcock & Wilcox Company, for an additional 20-year term. The Authority selected BE&K Construction Company (BE&K) and entered into an Engineering, Procurement, and Construction contract (EPC Contract) to perform the refurbishment. The Authority, with assistance from its Consulting Engineer, Malcolm Pirnie, Inc., developed the minimum technical requirements and negotiated the EPC Contract with BE&K. The design and procurement efforts were completed in early 2009 and on-site construction refurbishment activities commenced in November 2009. The refurbishment has a total estimated cost of $205 million. The refurbishment work is sequenced with the intent that one boiler train will remain operational to reduce the impact to the Authority’s landfill and maximize electrical production and revenues during the refurbishment period. This presentation will focus on the improvements to operations as a result of the refurbishment and its positive effects on the Authority’s integrated solid waste management system.

Full textAbstract:
The Mojave Desert and Mountain Recycling Authority is a California Joint Powers Authority (the JPA), consisting of nine communities in California’s San Bernardino County high desert and mountain region. In August 2008 the JPA contracted with Gershman, Brickner & Bratton, Inc. (GBB) to prepare the Victor Valley Resource Management Strategy (Resource Management Strategy). Working with RRT Design and Construction, Inc. (RRT), GBB prepared a coordinated forward-looking strategy to guide the JPA’s future program and facilities decisions. The Resource Management Strategy focused on the Town of Apple Valley, population 70,092, and the City of Victorville, population 107,408, the two largest JPA member communities, which have a combined total of more than 130,000 tons per year of material entering the JPA’s recycling system and the Victorville Landfill. The Resource Management Strategy is underpinned by a characterization of waste loads delivered to the Victorville Landfill. A visual characterization was carried out by RRT in September/October 2008. RRT engineers identified proportions of materials recoverable for recycling and composting among all loads collected from residential and non-residential generators for a full week, nearly 300 loads total. The JPA financed and manages the operations contract for the highly automated Victor Valley Material Recovery Facility (MRF). The MRF today receives and processes an average of 130 tons per day (tpd), five days per week, of single stream paper and containers and recyclable-rich commercial waste loads. The waste characterization indicated that as much as 80 percent of loads of residential and commercial waste currently landfilled could be processed for recycling and composting in a combination manual and automated sorting facility. Residue from the MRF, which is predominated by paper, would provide potential feedstock for an energy recovery project; however, the JPA has two strategies regarding process residue. The first strategy is to reduce residue rates from existing deliveries, to optimize MRF operations. An assessment of the MRF conducted by RRT indicated that residue rates could be reduced, although this material would continue to be rich in combustible materials. The second strategy is to increase recovery for recycling by expanding the recyclable-rich and organics-dense waste load deliveries to the MRF and/or a composting facility. The Resource Management Strategy provided a conceptual design and cost that identified projected capital and operations costs that would be incurred to expand the MRF processing system for the program expansion. Based on the waste composition analysis, residue from a proposed system was estimated. This residue also would be rich in combustible materials. The December 2008 California Scoping Plan is the roadmap for statewide greenhouse gas emission reduction efforts. The Scoping Plan specifically calls out mandatory commercial recycling, expanded organics composting (particularly food residue), and inclusion of anaerobic digestion as renewable energy. The Resource Management Strategy sets the stage for JPA programs to address Scoping Plan mandates and priorities. California Public Resources Code Section 40051(b) requires that communities: Maximize the use of all feasible source reduction, recycling, and composting options in order to reduce the amount of solid waste that must be disposed of by transformation and land disposal. For wastes that cannot feasibly be reduced at their source, recycled, or composted, the local agency may use environmentally safe transformation or environmentally safe land disposal, or both of those practices. Moreover, Section 41783(b) only allows transformation diversion credit (10 percent of the 50 percent required) if: The transformation project uses front-end methods or programs to remove all recyclable materials from the waste stream prior to transformation to the maximum extent feasible. Finally, prior to permitting a new transformation facility the California Integrated Waste Management Board is governed by Section 41783(d), which requires that CIWMB: “Hold a public hearing in the city, county, or regional agency jurisdiction within which the transformation project is proposed, and, after the public hearing, the board makes both of the following findings, based upon substantial evidence on the record: (1) The city, county, or regional agency is, and will continue to be, effectively implementing all feasible source reduction, recycling, and composting measures. (2) The transformation project will not adversely affect public health and safety or the environment.” The Resource Management Strategy assessed two cement manufacturers located in the high desert region for their potential to replace coal fuel with residue from the MRF and potentially from other waste quantities generated in the region. Cement kilns are large consumers of fossil fuels, operate on a continuous basis, and collectively are California’s largest source of greenhouse gas emissions. The Resource Management Strategy also identified further processing requirements for size reduction and screening to remove non-combustible materials and produce a feasible refuse derived fuel (RDF). A conceptual design system to process residue and supply RDF to a cement kiln was developed, as were estimated capital and operating costs to implement the RDF production system. The Resource Management Strategy addressed the PRC requirement that “all feasible source reduction, recycling and composting measures” are implemented prior to approving any new “transformation” facility. This planning effort also provided a basis for greenhouse gas reduction analysis, consistent with statewide initiatives to reduce landfill disposal. This paper will report on the results of this planning and the decisions made by the JPA, brought current to the time of the conference.

Full textAbstract:
Abstract All human activities generate negative externalities, in particular the use of radioactive material for electricity production and radioisotope applications. Both activities produce radioactive waste, which can, therefore, be considered as being specific externalities. The purpose of the paper is to investigate these externalities and to identify appropriate internalisation instruments. Analogue cases in environmental management are discussed. In general the nuclear externalities are not internalised in the management costs charged by Radioactive Waste agencies (RAWA). The paper explores the possibility of having an internalisation of all costs as requested by the strict application of the Polluter Pays Principle. In the case of electricity production a comparison is made between the externalities attributed to nuclear waste and those in relation with CO2-emissions from the combustion of fossil fuel. A brief overview is given on the evaluation approach in ExternE (“Externalities of Energy”). The evaluations are the basis for the design of a carbon tax applicable to fossil fuels for reducing CO2-emissions. A similar tax could be charged on radioactive waste management. Beyond the internalisation objective, the tax proceeds could finance the technological R&D for improving the conditions of storage and disposal, and provide compensations to local residents in the vicinity of nuclear waste management facilities. The management of spent radioisotope equipment in medicine, research, or industry is shown to have similar features to the management of packages, spent electrical appliances, and the disposal of batteries. In general the price of management of the spent material is not included in the purchase price. In case of spent radioisotope equipment, the externality mainly represents the risk of this material becoming a hazard for the public health. It is recommended to internalise the full costs of management to eliminate this risk. Moreover spent material should be registered and RAWA should maintain detailed inventories on their national territories. In order to induce the free return of spent material to the RAWA, deposit refund systems could be set in place as in the package or battery market. A surcharge is paid by purchase, which is refunded to the buyers when they return the product for recycling or proper disposal. The paper concludes by describing lessons and possible implications of the previously discussed environmental tax or surcharge systems on the way the Polluter-Pays Principle is applied in radioactive waste management.

Full textAbstract:
New Hanover County, NC, hired Gershman, Brickner & Bratton, Inc. (GBB) to help prepare a Request for Proposals (RFP) for the management and long-term operations of the County’s solid waste disposal facilities, which include a secure landfill with more than 40 years of remaining life, a 20+ year old waste-to-energy (WTE) plant, and seven recycling drop-off sites receiving over 200,000 tons per year. The RFP requested a single-service provider to provide all of the services currently being undertaken by the County under a single contract going forward. During the course of the procurement, GBB’s Project Manager made three presentations to the New Hanover County Board of Commissioners (County Board), advancing the RFP process from eight vendor proposals, to interviews of five firms and performing a technical and economic review of each, to short-listing two firms, to the final recommendation of going forward with high-tech start-up R3 Environmental LLC (R3). In September 2010, the County Board signed a landmark contract with R3 for the management of the County’s waste system that was intended to position the County as a world leader in innovative disposal, according to County officials. Under the agreement, R3 was to implement a modern Municipal Solid Waste (MSW) processing facility pulling out recyclables and making a low-ash, high-BTU Refused-Derived Fuel (RDF) biomass product, refurbishing the current mass-burn WTE facility into an RDF biomass-fired system, and implementing a new construction waste and demolition debris recycling (C&D) processing system. The new solid waste sorting facility, with advanced machinery, dubbed a “Smart MRF,” was expected to be in operation in two years, extracting recyclables and converting the organic waste stream into fuel. R3 guaranteed to divert over 80% of the incoming solid waste from the landfill. This paper provides a unique behind-the-scenes look at the procurement process used to select this “innovative technology proposal” from R3 as it pertained to recycling potential, carbon credits and renewable energy credits, and significant long-term cost benefits to the County. It will also provide a review of the vendor evaluation process that led to this landmark contract, from the RFP preparation, proposals evaluation, technical/economic reviews, short-listing, recommendations, and technical contract negotiation.
