Attitudes and actions towards recycling behaviours in the Limerick,Ireland region

Recycling across Ireland has increased incrementally since the introduction and implementation of the Landfill Directive 1999/31/EC, the WEEE directive 2002/96/EC, and the Waste Framework Directive 2008/98/EC. As a result of the implementation of the aforementioned directives, the volume of waste sent to landfill has fallen, household composting increased and recovery of municipal waste recyclables continues to improve. The improvements witnessed, are in part achieved as a result of the introduction of the 2-bin and 3-bin collection service. The improvement of facilities at recycling centres and bring banks have been instrumental in the gains achieved in recycling rates.NIMBYism, however, remains a constant impediment to procuring suitable sites for the recycling receptacles. It is not unusual for people to seek convenience whilst not wanting the associated problems on their doorstep. NIMBYism is something that most individuals are guilty of and it is considered to be quite normal. The structural difficulties associated with recycling rates are the first that need to be confronted. By altering the landscape, behaviours can be changed and improved. In the instance of bring banks and the social problems that are associated with them such as fly-tipping, changing the visual aspect of the receptacles and their positioning may improve recycling rates and reduce the number of instances of fly-tipping and littering.This paper presents the results of 509 questionnaires distributed to nine schools in the Limerick City and County environs. The questionnaires, distributed to primary schools actively participating in the Green School Programme, were analysed so as to get an understanding of the motivations and the deterrents surrounding household recycling of waste. From the analysis recommendations are made to reduce the social problems associated with bring banks and to increase the percentage of householders availing of waste collection services.

Present status of the recycling of waste electrical and electronic equipment in Korea

In Korea due to rapid economical growth followed by urbanisation, breakage of large traditional families into small nuclear families, continuous changes in equipment features and capabilities causes tremendous increase in sale of new electrical and electronic equipment (EEE) and decrease in sale of used EEE. Subsequently, the ever-increasing quantity of waste electrical and electronic equipment (WEEE) has become a serious social problem and threat to the environment. Therefore, the gradual increase in the generation of WEEE intensifies the interest for recycling to conserve the resources and protect the environment. In view of the above, a review has been made related to the present status of the recycling of waste electrical and electronic equipment in Korea. This paper describes the present status of generation and recycling of waste electrical and electronic equipment, namely TVs, refrigerators, washing machines, air conditioners, personal computers and mobile phones in Korea. The commercial processes and the status of developing new technologies for the recycling of metallic values from waste printed circuit boards (PCBs) is also described briefly. Since 1998, three recycling centers are in full operation to recycle WEEE such as refrigerators, washing machines and air conditioners, having the total capacity of 880,000 units/year. All waste TVs are recently recycled on commission basis by several private recycling plants. The recycling of waste personal computers and mobile phones is insignificant in comparison with the amount of estimated obsolete those. Korea has adopted and enforced the extended producer responsibility (EPR) system. Korea is making consistent efforts to improve the recycling rate to the standards indicated in the EU directives for WEEE. Especially environmentally friendly and energy-saving technologies are being developed to recycle metal values from PCBs of WEEE.

Determination of toxic metals in discarded Liquid Crystal Displays (LCDs)

This study focused on the determination of the toxic metal content of Liquid Crystal Displays (LCDs) present in various Waste Electrical and Electronic Equipment (WEEE). The main objective was the identification and quantification of toxic metals detected in LCD panels. An experimental procedure which involved dismantling, shredding, pulverization, digestion and chemical analysis was followed for the sorting, separation and analysis of LCD monitors from various electronic devices that are currently on the market. Nine selected devices were examined, originated from four different types of e-waste (WEEE); TVs, computers, mobile phones and tablets. Eleven metals were measured in all examined samples. In addition, concentration values of chromium (Cr), cadmium (Cd), lead (Pb) and mercury (Hg) were compared with the respective limits set by the RoHS 2002/95/EC Directive that was recently renewed by the 2012/19/EU recast. The comparison revealed that the examined toxic metals on LCD panels did not exceed the limits set by the European Union (EU). Furthermore, when results were compared to the TTLC regulatory limits it was revealed that in three samples As concentrations were higher than the limit. Finally, when the TCLP test was implemented the aforementioned samples did not exhibit proportionally elevated values in their leachates.

Stakeholder participation and the water framework directive: The case of the Ribble Pilot

The Water Framework Directive is the most significant piece of European water legislation to date. This paper looks at the Directive's stakeholder participation requirements, which are crucial to its successful implementation, and represent one of its most novel and potentially far-reaching elements. The Ribble catchment in northwest England is part of a European pilot river basin network tasked by the European Commission with testing the Directive's common implementation strategy guidance, which is designed to aid member states in meeting its requirements. The Ribble pilot, managed by the Environment Agency, is responsible for testing the stakeholder participation element of this guidance. This paper provides an overview of the early stages of the Ribble pilot'sapproach, and discusses stakeholder participation in the context of the Water Framework Directive more broadly.     

Sound management of brominated flame retarded (BFR) plastics from electronic wastes: State of the art and options in Nigeria

Management of flame retarded plastics from waste electrical and electronic equipment (WEEE) has been posing a major challenge to waste management experts because of the potential environmental contamination issues especially the formation of polybrominated-dioxins and -furans (PBDD/F) during processing. In Nigeria, large quantities of electronic waste (e-waste) are currently being managed—a significant quantity of which is imported illegally as secondhand electronics. As much as 75% of these illegal imports are never reused but are rather discarded. These waste electronic devices are mostly older equipment that contains brominated flame retardants (BFRs) such as penta-brominated diphenyl ethers (PBDEs), and polybrominated biphenyls (PBBs) which are presently banned in Europe under the EU WEEE and RoHS Directives. Risk assessment studies found both to be persistent, bio-accumulative and toxic. The present management practices for waste plastics from WEEE in Nigeria, such as open burning and disposal at open dumps, creates potential for serious environmental pollution. This paper reviews the options in the environmentally sound management of waste plastics from electronic wastes. Options available include mechanical recycling, reprocessing into chemicals (chemical feedstock recycling) and energy recovery. The Creasolv^® and Centrevap^® processes, which are the outcome of the extensive research at achieving sound management of waste plastics from WEEE in Europe, are also reviewed. These are solvent-based methods of removing BFRs and they presently offer the best commercial and environmental option in the sound management of waste BFR-containing plastics. Because these developments have not been commercialized, WEEE and WEEE plastics are still being exported to developing countries. The industrial application of these processes and the development of eco-friendlier alternative flame retardants will help assure sound management of WEEE plastics.     

Cause,catalyst or conjunction? The influence of the Habitats Directive on policy instrument choice in Member States

In the process of implementing EU policy, Member States sometimes introduce new policy instruments in cases where this is not obligatory. To better understand this phenomenon, this paper reviews three cases in which new instruments emerged and develops a methodology to trace back the influence of EU Directives on instrument choice. The method is illustrated by a narrative of the emergence of new management planning instruments during the implementation of the EU Habitats Directive in three EU Member States: Finland, Hungary and the Netherlands. Three key features of a policy instrument are defined, namely, its authoritative force, action content and governance design. These are used to measure the contribution of the Habitats Directive compared to other potential explanatory causes for the emergence of the new policy instrument. In all three reviewed countries a nested causal relationship between the Habitats Directive and the introduction of the new policy instrument is identified. Based on the relative contribution of the Habitats Directive to the emergence of the new instrument a distinction is made whether the Directive acted as a cause, catalyst or if conjunction occurred.     

River Restoration in Spain: Theoretical and Practical Approach in the Context of the European Water Framework Directive

River restoration is becoming a priority in many countries because of increasing the awareness of environmental degradation. In Europe, the EU Water Framework Directive (WFD) has significantly reinforced river restoration, encouraging the improvement of ecological status for water bodies. To fulfill the WFD requirements, the Spanish Ministry of the Environment developed in 2006 a National Strategy for River Restoration whose design and implementation are described in this paper. At the same time many restoration projects have been conducted, and sixty of them have been evaluated in terms of stated objectives and pressures and implemented restoration measures. Riparian vegetation enhancement, weir removal and fish passes were the most frequently implemented restoration measures, although the greatest pressures came from hydrologic alteration caused by flow regulation for irrigation purposes. Water deficits in quantity and quality associated with uncontrolled water demands seriously affect Mediterranean rivers and represent the main constraint to achieving good ecological status of Spanish rivers, most of them intensively regulated. Proper environmental allocation of in-stream flows would need deep restrictions in agricultural water use which seem to be of very difficult social acceptance. This situation highlights the need to integrate land-use and rural development policies with water resources and river management, and identifies additional difficulties in achieving the WFD objectives and good ecological status of rivers in Mediterranean countries.     

The impact of the European landfill directive on waste management in the United Kingdom

The European Union Landfill Directive calls on member states to reduce the amount of biodegradable municipal solid waste disposed of to landfill. In addition, national waste strategies will require the constituent parts of the United Kingdom to achieve increased household waste recycling and recovery rates. Both these measures will require the development of the infrastructure to support national high-intensity recycling and composting schemes and the construction of at least 35 new municipal waste to energy incinerators. Before plans can be developed for meeting the targets several areas relating to municipal solid waste need to be clarified. Depending on the definition of municipal solid waste, its composition and likely future growth rates the number of incinerators required could be up to 170.     

Policy And Practice Environmental Assessmentand Planning: A Chronology of Development in England and Wales

The development of regulations to implement Environmental Impact Assessment (EIA) in England and Wales occurred initially as a response to European Community Directive obligations. Since then, a proliferation of regulations has resulted from the need to meet those obligations which were not covered successfully by the first tranche of legislation; the desire to extend the range of project types requiring EIA beyond those specified in the Directive; and the need to respond to changes brought about by privatization.As a result, current regulations relating to EIA are extremely complex and are in a constant state of flux. This inevitably causes problems for those responsible for their implementation. Ten years after the 1985 Environmental Impact Assessment Directive was notified to the Member States, it has undergone a review and the European Commissionhas reached a common position on the proposedamendments.The implementation date for Member States to meet the requirements of the amended Directive is 31 December 1997 (ENDS, 1996). However, the 1985 Directive has yet to be fully implemented in the UK.

Value from shredder waste: Ongoing limitations in the UK

Shredder residue is the residue from the shredding of end-of-life vehicles and white goods, after removal of the main metals. Approximately 850,000 tonnes of shredder waste is produced in the UK each year, and historically sent to landfill. Due to European legislation such as the End-of-Life Vehicle (ELV) Directive and the Landfill Directive there is pressure to minimise this waste through recycling and recovery.In this paper, primary data are presented showing that 40% of materials are potentially recoverable in the coarser fraction of UK automotive shredder residue (>30 mm). Barriers to such recycling are discussed in the context of several recent drivers, including this waste's possible reclassification as hazardous.The lack of full and timely implementation of the ELV Directive in the UK has made it an ineffective driver, and it is now unlikely that its 2006 recycling targets will be met as intended.     

A comparison of biodegradable municipal waste (BMW) management strategies in Ireland and the Czech Republic and the lessons learned

In order to meet the recycling and recovery targets set forth by the European Union's (EU) Waste and Landfill Directives, both the Irish and Czech governments’ policy on waste management is changing to meet these pressures, with major emphasis being placed upon the management of biodegradable municipal waste (BMW). In particular, the EU Landfill Directive requires reductions in the rate of BMW going to landfill to 35% of 1995 values by 2016 and 2020 for Ireland and the Czech Republic, respectively. In this paper, the strategies of how Ireland and the Czech Republic plan to meet this challenge are compared. Ireland either landfills or exports its waste for recovery, while the Czech Republic has a relatively new waste management infrastructure. While Ireland met the first target of 75% diversion of BMW from landfill by 2010 and preliminary 2012 data indicate that Ireland is on track to meet the 2013 target, the achievement of the 2016 target remains at risk. Indicators that were developed to monitor the Czech Republic's path to meeting the targets demonstrate that it did not meet the first target that was set for 2010 and will probably not meet its 2013 target either. The evaluation reports on the implementation of Waste Management Plan of Czech Republic suggest that the currently applied strategy to divert biodegradable waste from landfill is not effective enough. For both countries, the EU Waste Framework and Landfill Directives will be a significant influence and driver of change in waste management practices and governance over the coming decade. This means that both countries will not only have to invest in infrastructure to achieve the targets, but will also have to increase awareness among the public in diverting this waste at the household level. Improving environmental education is part of increased awareness as it is imperative for citizens to understand the consequences of their actions as affluence continues to grow producing increased levels of waste.     

Sustainability assessment of national rural water supply program in Tanzania

Sustainability of rural water supply programs in developing countries is still an elusive goal. It is widely accepted that, as a rule, they have failed to deliver benefits to society in the long run. Emphasis has frequently been placed on the short‐term activities. Fast production of new schemes is thus a common strategy, prioritizing the engineering component, while sidestepping social and participatory issues and community empowerment. In 2006, the Government of Tanzania launched a national program to meet water sector targets set out in the Millennium Development Goals by the year 2015. In this study we evaluate key features of the program on a sustained basis. There is evidence that the Government is promoting more sustained facilities, focusing on cost recovery and on ‘decentralization by devolution’. Nevertheless, there are several shortcomings which threaten the long‐term functionality of the infrastructure that has to be built. In light of the implementation of the program, and based on the outputs of its pilot phase, we review the factors that can determine its sustainability.     

Ten Years On: An Empirical Analysis of UK Environmental Statement Submissions since the Implementation of Directive 85/337/EEC

Regulations to implement Directive 85/337/EEC have been in operation in the UK for over 10 years. Implementation of the amended Directive (97/11/EC) in March 1999 marked the start of a new phase in environmental impact assessment (EIA), and so a review of the impact of the original Directive upon EIA activity is timely. This paper examines the implementation of the Directive in the UK through an empirical analysis of the publication of environmental statements (ESs) between July 1988 and April 1998. ES submissions are analysed under Annexes I and II of the Directive and under the main UK regulations, and then development control decision outcomes are considered. The implications of selected legislation and policy initiatives for ES submissions are then investigated in detail for four types of project. The Directive has been a major force in stimulating the development and growth of EIA in the UK, although the interaction of policies and legislation (environmental and otherwise) can exert an important influence upon trends in ES submissions.     

Valuing environmental damage remediation and liability using value estimates for ecosystem services

The European Environmental Liability Directive aims to ensure that damaged habitats are restored where possible, but allows for complementary remediation with replacement habitat where restoration is not possible within a reasonable time. It also allows for compensatory remediation of the resource based on an assessment of environmental values in cases where there are interim social losses. This paper concurs with the argument that physical remediation without consideration of social values can fail to be equivalent to the resource that has been lost. Using, as a case study, a river in Ireland, it demonstrates that estimating social value can be challenging in practice, noting also differences between the value of environmental gains and losses. The paper argues that estimates of final ecosystem service values, including wastewater treatment costs, can provide a measure of social value and makes a case for the systematic collection of these data to inform decision-making.     

Monetary assessment of the recreational benefits of improved water quality – description of a new model and a case study

The European Union Water Framework Directive (WFD) has created a demand for comparing the benefits and costs of the remedial measures. A major part of the benefits from improved water quality relate to the increased recreational value. However, there is a lack of easily operative and widely applicable quantitative methods to assess the benefits of improved water quality for recreational use. We present a new model to link physical indicators of water quality, water feasibility indicators for different recreational uses, individuals’ perceptions concerning the current feasibility of water for recreational purposes and monetary measures of water-related recreation benefits. The model has been applied to nine lakes, three rivers and one large coastal area in Finland. In this paper, we present the principles of the method and the results from one case study. In Finland, the method has been applied for the economic analysis required in the WFD.
