Euro-trash: searching Europe for a more sustainable approach to waste management

How an economically affordable, environmentally effective and socially acceptable municipal solid waste management system can be developed is currently unclear. Considerable research has been carried out on the practical aspects of municipal waste management (i.e. transport, treatment and disposal) and how citizens feel about source separation, recycling, incineration and landfill but the perspective of the waste manager within the context of long term planning is often ignored. In this study, waste managers from 11 different leading-edge European municipal solid waste programs in nine different countries were interviewed. The economic, social, political, environmental, legal and technical factors of their specific programs were explored and analyzed. The transition of municipal solid waste management to urban resources management was observed and key ‘system drivers’ for more sustainable waste management practices were identified. Programs visited were: Brescia (I), Copenhagen (DK), Hampshire (UK), Helsinki (FI), Lahn-Dill-Kreis (D), Malmö (SE), Pamplona (E), Prato (I), Saarbrücken (D), Vienna (A), and Zürich (CH).     

Solid waste management in European countries: a review of systems analysis techniques

In the past few decades, solid waste management systems in Europe have involved complex and multi-faceted trade-offs among a plethora of technological alternatives, economic instruments, and regulatory frameworks. These changes resulted in various environmental, economic, social, and regulatory impacts in waste management practices which not only complicate regional policy analysis, but also reshape the paradigm of global sustainable development. Systems analysis, a discipline that harmonizes these integrated solid waste management strategies, has been uniquely providing interdisciplinary support for decision making in this area. Systems engineering models and system assessment tools, both of which enrich the analytical framework of waste management, were designed specifically to handle particular types of problems. Though how to smooth out the barriers toward achieving appropriate systems synthesis and integration of these models and tools to aid in the solid waste management schemes prevalent in European countries still remains somewhat uncertain. This paper conducts a thorough literature review of models and tools illuminating possible overlapped boundaries in waste management practices in European countries and encompassing the pros and cons of waste management practices in each member state of the European Union. Whereas the Southern European Union (EU) countries need to develop further measures to implement more integrated solid waste management and reach EU directives, the Central EU countries need models and tools with which to rationalize their technological choices and management strategies. Nevertheless, considering systems analysis models and tools in a synergistic way would certainly provide opportunities to develop better solid waste management strategies leading to conformity with current standards and foster future perspectives for both the waste management industry and government agencies in European Union.     

MANAGEMENT AND POLICY EFFECTS ON POTENTIAL GROUNDWATER CONTAMINATION FROM DAIRY WASTE1

ABSTRACT: A combined economic and water quality modeling framework was used to evaluate impacts of alternative policies and management practices on reducing nitrate movement to groundwater for dairy farms in Rockingham County, Virginia. The analysis considers three on-farm manure storage options, cost-sharing programs for purchasing manure storage facilities, restrictions on nitrogen application rates, and a tax on commercial fertilizer. The CREAMS model was used to estimate nitrate leaching from the crop root zone for various nutrient (and manure) management practices, based on timing and rate of manure and fertilizer applications. The mixed-integer programming economic model considers water quality, policy, and economic constraints in comparing the profitability of alternative cropping and nutrient management systems that reduce groundwater contamination potential. The study provides both the environmental and economic effects of better management of dairy waste.     

生活垃圾强制分类形势下的多源废荧光灯管回收管理机制建议

Assessing instruments for mixed household solid waste collection services in the Flemish region of Belgium

Instruments to reduce waste can be divided into three groups: first, pecuniary incentives; second, service level; finally, measurements stimulating prevention and waste reduction. Also specific characteristics of the community determine the amount of waste generated. We evaluate whether findings in literature on effectiveness of policy measures are valid for Belgium, specifically for the Flemish region. The policy mix instituted by the Flemish authorities in the ‘implementation plan household waste 2003–2007’ and implemented by local authorities, is assessed. Multiple regression analysis identifies those measurements having the greatest impact on household solid waste.We found an income elasticity of 0.326. Also the provided service level has a significant impact. Pecuniary incentives are effective instruments in reducing waste, with a price elasticity of −0.139. Furthermore, a higher percentage of direct costs, directly attributable to waste services, borne by households, reduces waste. A consequent implementation of the ‘polluter pays’ principle proves to be effective.

Spatial and temporal distribution of illegal dumping sites in the nature protected area: the Ojców National Park,Poland

The existence of illegal dumping continues to be a worldwide problem, even in nature protected areas, and its distribution is not random. An understanding of the distribution of illegal dumping sites is crucial for the enhancement of effective waste management systems. Therefore, this study aims at a better understanding of spatial and temporal changes to illegal dumping sites in a nature protected area (the Ojców National Park) from 1994 to 2016. The most important spatial factors that control the distribution of illegal dumping sites were the distance from roads and from the field-forest edge. In the last two decades, the number of small dumping sites has increased, whereas the number of large illegal dumping sites has decreased. Moreover, this study presents a model of the potential occurrence of illegal dumping sites, which indicates places that should be under the control of the national park and of local authorities.     

‘The biggest challenge is that we have to tell people how to sort.’ Waste management and the processes of negotiation of environmental citizenship in Slovenia

ABSTRACT

This article departs from the concept of environmental citizenship. Focus is on the experiences of representatives for Slovenian municipal waste management companies and business sector service companies engaged in the collection and recycling of electronic waste, and their attempts to increase the amount of separately collected municipal waste. They do so by engaging the Slovenian citizens to undertake separate sorting. Theoretically, the focus is on the processes of negotiating citizen engagement and, more specifically, attempts to incentivise the separate sorting of municipal waste which, it is argued, also helps foster the image of a particular kind of citizen. This article understands the informants’ experiences as being intimately linked to, and constitutive of, contemporary waste management discourses where attention is increasingly paid to the activities and behaviours of individual citizens. Noteworthy, while the concept of environmental citizenship can be said to allow citizens to practise sustainability (a concept that is otherwise seemingly quite abstract), the waste management policies of today seem to be increasingly relying on this active citizenship. It is at the intersection of these phenomenon that the negotiation practices of Slovenian waste management authorities happen.

Issues for small businesses with waste management

Participation by small and medium enterprise (SME) in corporate social responsibility issues has been found to be lacking. This is a critical issue, as individually SMEs may have little impact on the environment but their collective footprint is significant. The management style and ethical stance of the owner-manager affects business decision making and therefore has a direct impact on the environmental actions of the business. Although adoption of environmental practices to create competitive advantage has been advocated, many businesses see implementation as a cost which cannot be transferred to their customers. After a brief review of pertinent literature this paper reports on an exploratory investigation into the issue. Results show that whereas owner-managers of small enterprises express concern regarding the environment, this does not then translate into better waste management practices.
