The paradox of packaging optimization – a characterization of packaging source reduction in the Netherlands

The European Council Directive 94/62/EC for Packaging and Packaging Waste requires that Member States implement packaging waste prevention measures. However, consumption and subsequently packaging waste figures are still growing annually. It suggests that policies to accomplish packaging waste prevention do not suffice, especially since developments are less insightful as these are part of a self-declaring compliance system. This study is aimed at expanding the understanding of packaging source reduction. We collected and evaluated 131 available options implemented in the Netherlands in the period 2005–2010. Lightweighting has been identified as the most frequently applied packaging source reduction method, indicating that the packaging industry prioritizes low-effort and familiar concepts, despite the dichotomy in efficacy.     

Modes of governing Canadian waste management: a case study of Metro Vancouver’s energy-from-waste controversy

Managing municipal solid waste is a pressing environmental and political concern for Canadian municipalities who bear the primary responsibility for waste management (WM). In 2015, Metro Vancouver’s (MV’s) plans to expand their capacity to expand their WM capacity with energy-from-waste technology was abandoned, despite shrinking landfill space and persistent public opposition to new landfills. Using Bulkeley et al.’s [(2005). Governing municipal waste: towards a new analytical framework. Journal of Environmental Policy and Planning, 7(1), 1–23. doi:10.1080/15239080500251700] ‘modes of governing framework’, we analyse MV’s failed attempt to expand their energy-from-waste capacity to better understand the challenges associated with governing WM in Canada. We argue that a history of downloading responsibility for WM to municipalities, regional districts, and industry has fragmented WM governance, posing a challenge for developing new waste infrastructure. We find that this localization of responsibility is incompatible with contemporary WM challenges. The scalar mismatch between waste’s material impacts and the scale at which waste is managed has resulted in co-dependence and conflict between putatively independent municipalities, regional districts, and private companies. This inhibits higher-level WM coordination while the autonomy of individual municipalities is simultaneously undermined.     

The evolution of municipal waste management in Europe: how different are national regimes?

The 1994 European Directive on Packaging and Packaging Waste allowed a diversity of conceptions of waste management to be developed and tested in various countries. Such a diversity may raise drawbacks related to the achievement of the single market and the European law of competition. The paper describes the main differences in waste management regimes in five countries: France, Germany, the Netherlands, Italy and Greece. This comparative approach allows us, first, to identify four main variables in order to characterize policy regimes, explaining the degree of orientation of waste regimes to cost-effectiveness. Second, we will show that implementation has resulted, in each country, in learning, correction and self-regulation, thus reducing the initial divergences between national regimes. Hence, efficient harmonization of waste management regimes may be achieved unexpectedly in a soft way without passing stringent European directives. Moreover, if policy-makers were to adopt explicitly the option of experimenting with competing organizational and policy concepts, as an approach to European harmonization, it would reveal, by 2004, the cost-effectiveness of alternative solutions at a time when European policy has to be reconsidered.

A multi-criteria decision analysis of solid waste treatment options in Pakistan: Lahore City—a case in point

Population of the world is increasing day by day, resulting in enormous amount of waste production. In the modern age of great technological advancements, there needs to be a systematic method to keep the environment clean. The waste management activities, i.e., collection, transport and disposal, pose a great challenge to the waste managers as they have to factor in various eclectic factors such as land availability, facilities available, budget, time required and the impact it would have on the environment, while tackling this problem. Lahore, despite being the most developed city of Pakistan, does not have a suitable solid waste management system. An increasing population leads to more waste generation, and in Lahore the situation is no different. Several waste management companies are working in the city, but as of yet they have not been able to make significant inroads to completely eradicate the problem. The aim of this paper is to suggest a suitable way for dealing with the waste. To accomplish this aim, a hierarchy-based model is used, considering six criteria and five alternatives. We used multi-criteria decision analysis to decide among different waste management alternatives. Forecasting has been used to find the population and waste produced over the years. Analytical hierarchy process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) are used to rank the feasible alternative. The results show that the population and waste were increasing drastically. Aerobic digestion was ranked as the best alternative for waste management according to AHP and TOPSIS, but there is great variation among the rank of other alternatives.     

Co-pyrolysis of paper waste and mustard press cake in a semi-batch pyrolyzer—optimization and bio-oil characterization

Under the present research study, the co-pyrolysis of paper waste and mustard press cake was conducted in a 50 mm diameter and 640 mm long semi-batch pyrolyzer in the temperature range of 673 to 1173 K in nitrogen atmosphere and synergistic relationship between the pyrolysis of two feed stocks has been observed. The paper wastes were composed of local packing paper, newspaper-based food packets of grocery, and printing paper in the ratio of 6:3:1. During co-pyrolysis, response surface methodology (RSM) technique has been employed using Design Expert Version 7.0.0 to determine the collective effects of factors, namely, A: ratio of paper waste to mustard press cake and B: pyrolysis temperature, on the yield of bio-oil, energy yield, and oxygen content of bio-oil. Optimization has been done by using RSM to identify the individual sets of values of independent parameters corresponding to maximum bio-oil yield (A: 9.0:1, B: 874.75 K), energy yield (A: 8.80:1, B: 812 K), and minimum oxygen content of bio-oil (A: 2.75:1, B: 883.06 K). Bio-oil obtained at maximum energy yield condition has been characterized using the Gas chromatography–mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (FTIR) spectroscopic analyses. The array of compounds present in the bio-oil compounds has been compared with literature data available on pyro-oil obtained from similar feed stocks.     

Multi-objective optimization of waste and resource management in industrial networks – Part I: Model description

This article presents a general multi-objective mixed-integer linear programming (MILP) optimization model aimed at providing decision support for waste and resources management in industrial networks. The MILP model combines material flow analysis, process models of waste treatments and other industrial processes, life cycle assessment, and mathematical optimization techniques within a unified framework. The optimization is based on a simplified representation of industrial networks that makes use of linear process models to describe the flows of mass and energy. Waste-specific characteristics, e.g. heating value or heavy metal contamination, are considered explicitly along with potential technologies or process configurations. The systems perspective, including both provision of waste treatment and industrial production, enables constraints imposed upon the systems, e.g. available treatment capacities, to be explicitly considered in the model. The model output is a set of alternative system configurations in terms of distribution of waste and resources that optimize environmental and economic performance. The MILP also enables quantification of the improvement potential compared to a given reference state. Trade-offs between conflicting objectives are identified through the generation of a set of Pareto-efficient solutions. This information supports the decision making process by revealing the quantified performance of the efficient trade-offs without relying on weighting being expressed prior to the analysis. Key features of the modeling approach are illustrated in a hypothetical case. The optimization model described in this article is applied in a subsequent paper (Part II) to assess and optimize the thermal treatment of sewage sludge in a region in Switzerland.     

Can area managers connect policy and tenants? Implementation and diffusion of a new waste management system in Linköping,Sweden

Recycling and reducing household waste are political goals internationally, nationally and locally. In Sweden, households in apartment buildings seem to sort their waste to a lesser extent than households in single-family houses. This paper analyses the challenges of the diffusion of a new waste management system in apartment buildings, and focuses on a municipal housing company and the actions of its area managers. It is argued that area managers can be regarded as street-level bureaucrats who act as ‘collectors’ of tenants’ everyday practices in the studied implementation process. The study is based on interviews, document analysis and observations.     

Abatement cost curves: a viable management tool for enabling the achievement of win-win waste reduction strategies?

Environmental regulation of industrial activity is generally believed to have a negative impact on the industry. Recent literature has suggested, however, that reducing industrial waste outputs can, in some circumstances, result in a 'win-win', or at least 'win-draw', scenario for industry and the environment. The viability of using the abatement cost curve method as a management tool to enable the achievement of a 'win-win' state is investigated here. Copper pollution in the Humber Estuary is used as a case-study, and the abatement cost curve methodology proves to be a valuable tool in identifying barriers to achieving the win-win state, and also in providing future direction for the waste management strategy. Abatement cost curves are concluded to be powerful management tools which greatly improve the transparency of waste reduction information.     

Multi-objective optimization of waste and resource management in industrial networks – Part II: Model application to the treatment of sewage sludge

In the present article, the thermal treatment of digested sewage sludge generated in the Swiss region of Zürich is modeled and optimized from an environmental perspective. The optimization problem is solved using a multi-objective mixed-integer linear program that combines material flow analysis, process models, life cycle assessment (LCA), and mathematical optimization techniques. The treatment options include co-incineration in municipal solid waste incineration, co-processing in cement production, and mono-incineration with the prospect of phosphorus recovery. The model is optimized according to six environmental objectives. Five of the six single-objective optimal solutions involve splits over the treatment options. The results reflect the available treatment capacities and other constraints, aspects rarely considered in conventional LCA studies. Co-processing in cement production is used to the maximum extent possible when minimizing impacts on climate change, human toxicity, fossil resource depletion, and fully aggregated impacts (ReCiPe H/A), whereas mono-incineration with phosphorus recovery receives the bulk of the sludge when optimizing for ecotoxicity and mineral resource depletion. Four of the single-objective optimal solutions (minimization of fossil energy resource depletion and contribution to climate change, human toxicity, and fully aggregated impacts) outperform the reference case over the six impact categories considered, showing that the current situation can be improved in some environmental categories without compromising others. The results of the sensitivity analysis indicate that assumptions regarding the product systems displaced by recovered by-products are critical for the outcome of the optimization. Our approach identifies in all of the cases solutions in which significant environmental improvements can be attained.     

Critical analysis of the waste management performance of two uranium production units in Brazil--part I: Poços de Caldas production centre

Waste management strategies in mining projects will depend to a large extent on the characteristics of the operational process, the type of ore and prevailing socio-environmental conditions, amongst other issues. The expenditures required by the management scheme and the implementation of remediation programs will be determined by the extent that the above issues were considered in the planning phase of the project. Several works have been published in the literature concerning the analysis of waste management programs and environmental impacts associated with uranium projects around the world. However, the vast majority do not report a comprehensive assessment integrating the various relationships among operational process, environmental impact, remediation strategy and costs. This study, divided into two papers, presents a detailed critical analysis of the waste management strategies adopted in two uranium production centres in Brazil, i.e., the Poços de Caldas Project (Part I) and the Caetité Project (Part II). The operational processes are described and the environmental impacts of the generated wastes as well as the adopted management strategies and costs are examined. Also, in Part II, a comparison between both production centres is made emphasizing the impacts of environmental and social-economical issues on the overall assessment.     

Implementation of the European IPPC Directive—BAT guidelines for the cement industry in Cyprus

The European Integrated Pollution Prevention and Control (IPPC) Directive 96/61/EC aims to introduce a European-wide system of integrated prevention and control of pollution in order to secure a high level of protection to the environment as a whole. It places obligations on the Member States (MS) to introduce controls that ensure operators comply with the Directive. In this framework, as a part of the implementation process leading to formal accession of Cyprus to the European Union, the National Technical University of Athens has examined all documents related to the Best Available Techniques (BATs) published by Institutes and Organisations, such as the Institute for Prospective Technological Studies in Spain, the Environmental Protection Agency in Ireland, the World Bank Group and the Ministry for the Environment, Planning and Public Works in Greece. A series of guidelines were developed for the application of BATs for 14 categories of the Cypriot industry that fall into the IPPC Directive. The concept of BATs plays a central role in the Directive because it provides a basis for setting Emission Limit Values (ELVs) as well as the principal benchmark for determining the obligations of industrial operators in respect of pollution prevention and control. This paper presents the guidelines for cement manufacture in Cyprus.     

Drivers of local people’s participation in sustainable natural resource management: a case study in central Iran

The driving forces behind natural resource management (NRM) vary among countries. Most NRM programmes focus on biophysical drivers such as soil, water and vegetation, with little attention directed towards the nuanced sociocultural and religious drivers of sustainable natural resource management (SNRM) practices. This paper explores those understudied drivers that influence local people’s participation (LPP) in SNRM in Isfahan, Iran. Using a multi-stage stratified sampling method, we selected 200 natural resource experts and natural resource users to complete a questionnaire about their perceptions of SNRM. Results reveal that sociocultural and religious beliefs are the major drivers of SNRM. The results also indicate that subsidiary drivers include: a sense of responsibility towards SNRM; the conviction that natural resources belong to God and should therefore be preserved; participation to preserve natural resources because of training courses and media influence; a long-established custom of preserving natural resources; and the specific impact of environmental television programmes. Demographic analysis finds a significant relationship between educational level and LPP in SNRM. This study’s results therefore suggest that natural resource managers would benefit from a deeper understanding of the local sociocultural and religious contexts that motivate people to participate in SNRM.     

Is legislation a barrier to the sustainable management of game species? A case study of wild deer in Britain

Wild game management for hunting in Western society has become increasingly complex as stakeholders have multiplied and as ‘sustainability’ influences the contemporary debate. This paper questions whether the current legal framework for game management, which has evolved from early European civilisations to focus on ‘hunting rights’, is relevant to regulate the contemporary environmental, social and economic dimensions of wild game and their management. Employing a narrative analysis to focus on deer, the study identifies key legislative tenets and highlights the pertinence of historical laws to contemporary conflicts. The analysis suggests that current legislation is increasingly divergent from contemporary trends and has created inertia with respect to sustainable deer management. The paper offers four options to redress this: state intervention; voluntary collaboration; financial incentives; and establishing a legal responsibility for management. It is concluded that significant innovation is required in one or more of these four areas to facilitate the contemporary sustainable management of wild deer in Britain.     

Removal of chromium(VI) from electroplating industry wastewater using bagasse fly ash—a sugar industry waste material

A waste product generated in the sugar industry in India has been converted into a cheap potential adsorbent. This has been characterised and utilized for the removal of chromium (VI) from synthetic and actual wastewater. The sorption efficiency decreases with increase in pH. Adsorption of Cr (VI) on bagasse fly ash follows the Freundlich and Langmuir isotherms and these have been used to obtain the thermodynamic parameters of the process. The sorption capacity of this adsorbent for chromium removal is found to be comparable to other low cost adsorbents.     

The use of bio-waste to revegetate eroded land areas in Ylläs,Northern Finland: Toward a zero waste perspective of tourism in the Finnish Lapland

Lapland is one of the most attractive nature-tourism areas in Europe, and tourism is vital for local economy. However, recreational tourist activities such as skiing, hiking and horse riding deteriorate the unique and vulnerable nature of Northern Finland. Erosion and wearing of tourist areas negatively affects biodiversity and ecosystem services and reduce the attractiveness of the region. Tourism is also the source of other environmental disturbances such as wastes. Currently, in Lapland, the prevalent waste treatment method is disposal, and wastes are transported over long distances due to lack of recipient facilities for waste management. The suggestion for sustainable waste management Scenario presented in this paper is to find a synergistic solution to both of these problems, by local treatment of bio-waste in an anaerobic digestor and utilization of digestate to revegetate eroded land. It is proposed that bio-waste is co-digested with sewage sludge and offal from slaughterhouses in Ylläs in the municipality of Kolari. An estimated 500–1000 t of digestate could be produced and used in tourist areas annually. Experiences from existing seasonal bio-waste collection schemes and interviews of local tourist enterprises and tourists indicate that there is willingness to extend the source separation of wastes. Assessment of the digestion Scenario suggests that economic costs of investment could be offset by avoided costs and by additional environmental and social benefits. It is concluded that this zero waste approach could lead to an improved image of Lapland as a sustainable tourist destination.     

Realization of participation and spatiality in participatory forest management – a policy–practice analysis from Zanzibar,Tanzania

The efforts in sustainable natural resource management have given rise to decentralization of forest governance in the developing world with hopes for better solutions and effective implementation. In this paper, we examine how spatially sensitive participation is realized from policy to practice in the process of establishing participatory forest management in Zanzibar, Tanzania. Our policy–practice analysis shows that the policies in Zanzibar strongly support decentralization and local level participation has in practice been realized. However, the policy does not emphasize participatory process design nor address the possibilities of using spatial information and technologies to ensure wider participation. Thus, the practices fall short in innovativeness of using site-sensitive information with available technologies. Reflecting the Zanzibari Community Forest Management Agreements (CoFMA) context with examples of participatory use of spatial information and technologies in other parts of the world, we discuss ways to improve the Zanzibari CoFMA process towards increased participation, communication, local sense of ownership and more sustainable land management decisions, and argue for the future implementation of CoFMA as a spatially sensitive participatory process.     

An assessment of Spain's Programa AGUA and its implications for sustainable water management in the province of Almería, southeast Spain

Spain's Programa AGUA was proposed in 2004 as a replacement for the Spanish National Hydrological Plan and represented a fundamental policy shift in national water management from large inter-basin water transfers to a commitment to desalination. Twenty-one desalination facilities are planned for six provinces on the Spanish Mediterranean coast to supplement their water needs. These include the province of Almería that for the last 30 years has endured a net water abstraction overdraft leading to serious reservoir depletion and groundwater imbalances. Rising water use is a result of increasing demand to support irrigated agriculture (e.g. greenhouse horticulture) and for domestic needs (e.g. rapid urban growth and tourism development), which has led observers to question Almería's long-term water sustainability. Desalinated water alone is unlikely to be sufficient to make up these water deficits and water-users will have to accept a move to full-price water recovery by 2010 under the European Union (EU) Water Framework Directive of which Spain is a signatory. Anticipated water efficiencies resulting from higher water tariffs, increasing water reuse and water infrastructure improvements (including inter-basin transfers), in conjunction with increasing use of desalinated water, are expected to address the province's current water overdraft. However, Almería will need to balance its planned initiatives against long-term estimates of projected agricultural and domestic development and the environmental consequences of adopting a desalination-supported water future.     

Does Fair Trade Compete with Carbon Footprint and Organic Attributes in the Eyes of Consumers? Results from a Pilot Study in Scotland,The Netherlands and France

Several studies on ethical and social food attributes have shown that consumers, especially in developed countries, are willing to pay a price premium for fair trade foods products. However, there is a scant literature on how consumers’ preferences and willingness to pay (WTP) for fair trade products are affected by the presence of other ethical food attributes. To fill this gap, a choice experiment was conducted in Scotland, the Netherlands and France to assess consumers’ preferences and WTP for ethical attributes, i.e., fairtrade, organic, and lower carbon footprint, of bananas and to find out whether this ethical food attributes are competing in real markets. The results showed that in the three countries consumers are willing to pay a price premium for the three ethical food attributes. The results showed that in the current market situation these ethical foods are not generally competing against each other. Nonetheless, they are likely to become competing for consumer’s money at least when: (1) the price of organic foods is decreased significantly, (2) the price for fairtrade food products is set higher than consumers’ WTP, and (3) bananas labeled as having lower carbon footprint are made available in retail stores and sold at a price lower than consumers’ WTP.
