    Effects of waste quality and landfill technology on the long-term behaviour of municipal landfills1999In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 17, no 6, p. 413-423Article in journal (Refereed)
    Abstract [en]

    The pollution potential of old municipal landfills of the former German Democratic Republic (GDR) is not as bad as expected, even taking into consideration that most lack environmental protection systems. Compared with specific conditions in the former GDR (such as production and consumption), the disposal of waste and the long-term behaviour of landfills clearly differs from that in the old German federal states. Low quantities of deposited waste created slowly growing landfills, and therefore led to rapid degradation processes still in the aerobic milieu. As a result of the increasing similarity of waste quantities and composition in the new and old federal states after 1990, waste deposited today can be expected to have similar long- term behaviour and emissions as existing old Federal Republic of Germany (FRG) landfills which were operating during the 1970s and 1980s.

    Technology-neutral green procurement in practice: an example from Swedish waste management2012In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 30, no 5, p. 519-523Article in journal (Refereed)
    Abstract [en]

    Green public procurement has been criticized for its excessive reliance on detailed technology specifications, which can distort incentives in the short term and discourage innovation in the longer term. Economists therefore tend to prefer technology-neutral procurement, which rewards outcomes rather than technologies. However, technology-neutral procurement can also be problematic in practice. The present study investigated green public procurement of waste management, a rapidly growing field. In one of the most sophisticated models for technology-neutral procurement applied in Sweden in recent years, different environmental impacts were assigned weights, but no weight was given to the particular technology employed. Even here, however, potential inefficiencies were found where the scoring rule could have led to arbitrary, and presumably unwanted, outcomes. Explicitly assigning monetary surcharges to desirable and undesirable environmental effects may be a better way to reach environmental targets.

    Landfill site selection using geographic information system and analytical hierarchy process: A case study Al-Hillah Qadhaa, Babylon, Iraq2016In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 34, no 5, p. 427-437Article in journal (Refereed)
    Abstract [en]

    Al-Hillah Qadhaa is located in the central part of Iraq. It covers an area of 908 km2 with a total population of 856,804 inhabitants. This Qadhaa is the capital of Babylon Governorate. Presently, no landfill site exists in that area based on scientific site selection criteria. For this reason, an attempt has been carried out to find the best locations for landfills. A total of 15 variables were considered in this process (groundwater depth, rivers, soil types, agricultural land use, land use, elevation, slope, gas pipelines, oil pipelines, power lines, roads, railways, urban centres, villages and archaeological sites) using a geographic information system. In addition, an analytical hierarchy process was used to identify the weight for each variable. Two suitable candidate landfill sites were determined that fulfil the requirements with an area of 9.153 km2 and 8.204 km2. These sites can accommodate solid waste till 2030

    Evaluation of recycling programmes in household waste collection systems2010In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 28, no 7, p. 577-586Article in journal (Refereed)
    Abstract [en]

    A case study and a literature review have been carried out to address the two questions: how can waste flow data from collection systems be interpreted and compared? and which factors are decisive in the results of recycling programmes in household waste collection systems? The aim is to contribute to the understanding of how recycling programmes affect the quantity of waste and sorting activities. It is shown how the results from various waste sorting systems can be interpreted and made comparable. A set of waste flow indicators is proposed, which together with generic system descriptions can facilitate comparisons of different collections systems. The evaluation of collection systems depends on the system boundaries and will always be site-specific to some degree. Various factors are relevant, e.g. environmental objectives, technical function, operating costs, types of recyclable materials collected separately, property-close collection or drop-off systems, economic incentives, information strategies, residential structure, social codes, etc. Kerbside collection of recyclables and weight-based billing led to increased waste sorting activities in the case study. Forty-three decisive factors are listed and discussed.

    State-of-the-art treatment processes for municipal solid waste incineration residues in Japan2000In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 18, no 1, p. 41-51Article in journal (Refereed)
    Abstract [en]

    Solid residues from municipal solid waste incineration (MSWI) can be categorized as air pollution control residues (AR) and bottom ash (BA). Both categories pose a particular environmental threat on account of the risk of the release of dioxins and metals. In Japan, handling of MSWI residues is of major concern and the treatment of AR prior to landfilling is stipulated. Accepted treatment: techniques are melting, cementitious S/S (stabilization and solidification), stabilization with a chemical agent and acid extraction. These methods are reviewed and evaluated in this paper with respect to: quality; quantity and utilization of end products; treatment costs; energy demand and process reliability. Thermal processes are superior regarding dioxin removal as well as material recovery and reuse, but treatment costs can be as high as 60 000 Y t(-1), i.e. one order of magnitude higher than for other processes. Cementitious SIS and chemical stabilization are characterized by the ease of operation, but the solid waste mass is increased by up to 40 and 10 wt.-%, respectively. Acid extraction is a proven and reliable technique and is inexpensive: nevertheless, it has the smallest share of the market.

    Steel slag used in landfill cover liners: laboratory and field tests2010In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 28, no 12, p. 1114-1121Article in journal (Refereed)
    Abstract [en]

    Stricter rules for landfilling within the EU have led to the closure of many landfills and a need for large amounts of cover liner materials. Therefore, the potential utilization of mixtures of electric arc furnace slag (EAFS) and ladle slag (LS), which are currently deposited in landfills, as a material for use as landfill liner was investigated. Laboratory analyses showed the mixtures to have similar compression strength to that of high-strength concrete and low hydraulic conductivity (<10-11 m s-1 in some cases). However, both their hydraulic conductivity and compaction properties were strongly affected by the time between adding water to the mixtures and compacting them (tests showed that a delay of 24 h can lead to an increase in hydraulic conductivity, so it should be compacted as soon as possible after mixing the material with water). In addition, the performance of a cover liner constructed using EAFS and LS was studied in a 2-year field trial on a landfill for municipal solid waste, in which the average amount of leachate collected from ten lysimeters was only 27 L m-2 year-1, easily meeting Swedish criteria for the permeability of covers on non-hazardous waste landfills (≤50 L m-2 year-1). Thus, the material seems to have promising potential for use in barrier constructions.

    Changes in the phosphorus availability of a chemically precipitated urban sewage sludge as a result of different dewatering processes2000In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 18, no 3, p. 249-258Article in journal (Refereed)
    Abstract [en]

    The objective of this study was to compare the effects of different dewatering processes on the phosphorus (P) availability of an FeCl3precipitated and limeconditioned sludge having an initial dry matter content (DMC) of 4%. The sludge was dewatered by either drying (D), freezing/thawing (FT) or centrifugation (C) until a DMC of about 15% was reached. Thereafter the FT and D sludges were gently dried to obtain a DMC increasing up to 50 to 60%. The plantavailable sludge P was assessed by the change in the isotopic dilution of P taken up by ryegrass (Lolium perenne[L]) after sludge amendments to one soil. After the plant experiment, the soiltosolution transfer of P ions and bicarbonateand ammonium lactate extractable P were determined in selected soil samples. The amount of plantavailable P (Lvalue) and the contribution of sludge P to plant nutrition (%Pdfsl) in soil amended with nondewatered sludge (ND) were not significantly different from the L and percentage Pdfsl values of soils amended with FT, D and C sludges. Nor did the subsequent drying of D and FT sludges significantly change the L and percentage Pdfsl values. Hence, the dewatering processes did not significantly alter the initial sludge P availability. The soiltosolution transfer of P ions and the chemically extracted P did not significantly differ between the different sludgeamended soil samples. The percentage Pdfsl values can be predicted by percentage ΔE1, since the overall average relative increase (%ΔE1) in the immediate soiltosolution transfer of P ions did not significantly differ from the percentage Pdfsl values.

    Assessment of methane oxidation capacity of soils2004In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 22, no 1, p. 42-48Article in journal (Refereed)
    Abstract [en]

    Methane oxidation capacity of three soil matrices was assessed using a new method based on the pressure fall resulting from methane oxidation. The effects of incubation temperature, moisture and methane content on the oxidation capacity were studied. Parameters observed were non-methanotrophic oxygen consumption, methane assimilation, length of the lag period before steady pressure fall was reached, initial pressure fall and maximum pressure fall. Filling material taken from a biofilter was tested. The length of the lag period was an index of prior exposure of the soil to methane emissions. Incubation temperature of 30°C and soil moisture at the water-holding capacity were chosen to standardize the test. Oxygen depletion by non-methanotrophs varied between 40 and 60% of the total oxygen consumption while methane assimilation was at 40 to 50% of the total methane consumption.

    The use of by-products from metallurgical and mineral industries as filler in cement-based materials2003In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 21, no 1, p. 29-37Article in journal (Refereed)
    Abstract [en]

    This investigation has been made in order to make it possible to increase the use of by-products in cement-based materials. Use of by-products requires a screening procedure that will reliably determine their impact on concrete. A test procedure was developed. The most important properties were considered to be strength development, shrinkage, expansion and workability. The methods used were calorimetry, flow table tests, F-shape measurements, measurements of compressive and flexural strength and shrinkage/expansion measurements. Scanning electron microscopy was used to verify some results. Twelve byproducts were collected from Swedish metallurgical and mineral industries and classified according to the test procedure. The investigation showed that the test procedure clearly screened out the materials that can be used in the production of concrete from the unsuitable ones.

    Mobility and fractionation of arsenic, chromium and copper in thermally treated soil2011In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 29, no 1, p. 3-12Article in journal (Refereed)
    Abstract [en]

    Thermal treatment is used to remediate soil co-contaminated with organic and inorganic contaminants. It destroys organic contaminants, but the remaining inorganic contaminants require further treatment. In this study the effects of thermal treatment on the mobility, speciation and chemical fractionation of As, Cr and Cu in a CCA-polluted soil were evaluated by leaching tests, As speciation assays and a sequential extraction procedure. The soil was sieved into four size fractions (<0.125, 0.125—0.250, 0.250—0.500 and 0.500—1.0 mm), each of which was treated at 800°C and analysed in comparison with the untreated soil. The leaching of As and Cr increased by factors of 18—40 and 2—23, respectively, while the mobility of Cu decreased 12—14-fold after treatment. The concentration of As(V) in pore water of the finest soil fraction increased 19-fold, whereas that of As(III) remained constant. The treatment reduced As, Cr and Cu associated with the reducible soil fraction. In addition, it increased the proportions of As and Cr (slightly) associated with the exchangeable and acid-soluble soil fractions, and the proportions of Cu and Cr (substantially) associated with the residual fraction.

    Biological nitrogen removal from landfill leachate: A pilot-scale study1999In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 17, no 6, p. 493-497Article in journal (Refereed)
    Abstract [en]

    A pilot-scale two-stage process including an anaerobic pretreatment (up-flow anaerobic sludge blanket, UASB) unit and a pre-denitrification activated sludge process was studied for treating leachates from a municipal landfill (waste aged 4 to 5 years, area 2.5 ha) and from a windrow composting area (1 ha). A single-stage pilot process was used for nitrification studies. The leachate characteristics were as follows: COD 740 to 2400 mg l-1 (chemical oxygen demand), BOD7 (biochemical oxygen demand) approximately 1000 mg l-1, N(tot) 40 to 120 mg l-1 and the temperature was between 2 and 21°C. The results show that 45 to 50 COD removal could be achieved in the UASB reactor even at temperatures below 10°C. The activated sludge process was operated with a 1.1 to 2.2 d hydraulic retention time and at between 8 and 21°C. The removal efficiencies were 80 to 90 for COD, over 98 for BOD7, over 90 for NH4-N and over 70 for N(tot). The dependence of denitrification efficiency on leachate biodegradable COD fraction and COD to N ratio was evaluated. Overall treatment efficiencies were good and applicable for design purposes. The total costs were estimated for a full scale pre-denitrification process at FIM 10 to 20 m-3 and FIM 50 to 90 (kg N removed)-1 (3.5 to 7 DM m-3 and 17 to 30 DM [kg N removed]-1) for a landfill representing circumstances in Southern Finland with an annual average flow of 50 m3 d-1.

    Support for designing waste sorting systems: A mini review2017In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 35, no 11, p. 1099-1111Article in journal (Refereed)
    Abstract [en]

    This article presents a mini review of research aimed at understanding material recovery from municipal solid waste. It focuses on two areas, waste sorting behaviour and collection systems, so that research on the link between these areas could be identified and evaluated. The main results presented and the methods used in the articles are categorised and appraised. The mini review reveals that most of the work that offered design guidelines for waste management systems was based on optimising technical aspects only. In contrast, most of the work that focused on user involvement did not consider developing the technical aspects of the system, but was limited to studies of user behaviour. The only clear consensus among the articles that link user involvement with the technical system is that convenient waste collection infrastructure is crucial for supporting source separation. This mini review reveals that even though the connection between sorting behaviour and technical infrastructure has been explored and described in some articles, there is still a gap when using this knowledge to design waste sorting systems. Future research in this field would benefit from being multidisciplinary and from using complementary methods, so that holistic solutions for material recirculation can be identified. It would be beneficial to actively involve users when developing sorting infrastructures, to be sure to provide a waste management system that will be properly used by them.

    Leaching characteristics of fly ash from Chinese medical waste incineration2012In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 30, no 3, p. 285-294Article in journal (Refereed)
    Abstract [en]

    Many of the characteristics of typical medical waste ash can be found by using ash leaching experiments. The present study investigated the characteristics of fly ash derived from incineration of medical waste in China. The particle diameter of the fly ash was in the range 154-900 µm. Elemental analyses of the fly ash indicated that it contained calcium, aluminium, iron, sodium, potassium and magnesium, and that copper, lead, chromium and mercury were the dominant heavy metals it contained. As leaching time was increased the leaching concentrations of the heavy metals increased and the leaching toxicity was augmented. When the pH was neutral, the concentrations of most heavy metals in the leachate were minimum whereas when the pH was alkali or acid, the leaching toxicity was greatly enhanced. High temperature melting was found to be a good method of fixing heavy metals, and the main components of the sinter were Fe3O4, SiO2, CaSO4 and CaSiO3, etc.

    Cost-saving biological nitrogen removal from strong ammonia landfill leachate2011In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 29, no 8, p. 797-806Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to develop an improved management mode in Ammassuo landfill (Finland) for leachate ammonium-nitrogen removal, to minimize the leachate management costs and secure compliance with the uptrend requirements of regulations for on-site leachate management. With a single sequential batch simulation reactor, the minimum C/N ratio was detected as 1.7 (adjusted by external carbon addition), to achieve the acceptable removal efficiency of 99, 62 and 74% in NH(4)-N, total nitrogen and chemical oxygen demand, respectively. Both total nitrogen removal and efficiency of carbon use were correlated with an increasing NO(2)(-)/NO(x)(-) ratio indicating higher performance with denitrification via nitrite. It was estimated that the leachate management cost could be reduced by 28 to 38%.

    Optimization of landfill leachate management in the aftercare period2012In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 30, no 8, p. 789-799Article in journal (Refereed)
    Abstract [en]

    The management of sanitary landfills after closure is an important engineering, economic and sustainability issue and is referred to as the greatest unresolved landfill challenge. Most sanitary landfills are operated according to the dry tomb principle, resulting in aftercare periods of hundreds of years. To study landfill body behaviour, long-term leachate emissions were studied with anaerobic landfill simulators, and a forecast model was developed targeting the behaviour of NH4-N, COD and chlorides as a function of temperature and the L/S-ratio (liquid-to-solid). It was found that NH4-N is the decisive factor in leachate management, requiring the highest L/S-ratio (around 6) to meet the direct discharge limit values. Various scenarios were constructed to find optimal leachate management strategies both in large (waste height H = 25 m) and medium-sized landfills (H = 10 m) with corresponding temperature ranges. The results show that by minimizing the aftercare period length with leachate pre-treatment and recirculation, both sustainability and economic benefits can be achieved. The results provide new views on how to manage the long-term leachate aftercare problem. In the case of large landfills, further efforts are needed to reach stabilization within a reasonable time frame.

    Mechanical recycling of electronics scrap: the current status and prospects1998In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 16, no 2, p. 119-128Article in journal (Refereed)
    Abstract [en]

    Of the various mechanical metal recycling techniques employed in electronic scrap processing, air table separation, magnetic separation and eddy current separation technolo gies have proved to be the most commercially successful. In addition, it is very important, even indispensable, that, prior to the physical processing of electronic scrap, selective dis mantling and identification (if necessary) be employed. It is, however, recognized that problems such as process optimiza tion and organics handling remain and that in-depth charac terization of electronic scrap will be essential in this context.

    End-of-life electric and electronic equipment management towards the 21st century2000In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 18, no 1, p. 73-85Article in journal (Refereed)
    Abstract [en]

    With the rapid growth of the electronics industry and an evergrowing environmental awareness worldwide, an environmentally sound and economically viable management system for endoflife (EOL) electric and electronic equipment (EEE) is of great importance for sustainable development. Traditional recycling and processing of EOL electronics directed towards the recovery of copper and precious metals, will be faced with many challenges in the future. It has been recognized by the EOL EEE recycling industry that a new strategy for EOL EEE must be developed. In this paper, current status and future trends in EOL EEE management are presented. Selective dismantling of valuable and hazardous components is evaluated in terms of a graderecovery (GR) concept. It is concluded that selective dismantling and mechanical processing must be coordinated in such a way as to produce suitable materials for subsequent handling at the lowest cost. Furthermore, new developments in mechanical and thermal processing of EOL EEE are also discussed, which involve water table and eddy current separation techniques and reduction of dioxins and furans during combustion of the plastics containing halogenated flame retardants. In addition, the challenges and perspectives associated with EOL management of plastics and cathode ray tubes (CRTs) encountered in EOL EEE are highlighted in this paper. It is predicted that EEE, being designed for recycling in the 21st century, will be processed and recycled economically and ecologically on becoming obsolete.

    ISO 14001 adoption and industrial waste generation: the case of Swedish manufacturing firms2015In: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 33, no 2, p. 107-113Article in journal (Refereed)
    Abstract [en]

    Adoption of environmental management systems (EMSs) based on ISO 14001 has constituted one of the most important developments in sustainable industry management in recent years. Previous research on the impact of EMSs has relied heavily on corporate representatives’ subjective perception of benefits. Moreover, studies tend to focus on the systems’ impact on firms’ overall environmental performance, not distinguishing between the differences in different environmental aspects. This study aims to contribute knowledge about the influence of certified EMSs on industrial waste generation based on objective industrial waste data derived from mandatory annual environmental reports. The study focuses on changes in waste generation over a period of 12 years and includes both ISO 14001-certified firms (66 firms) and non-certified firms (50 firms). Consideration is given to the improvement efforts in the firms before EMS adoption. Analysis has been carried out using statistical methods for three different industrial waste parameters: hazardous waste, waste to landfill and the total amounts of waste. The results indicate that the certified EMSs have no statistically significant effect on any of the three waste parameters.
