Integrated pollution prevention and control for heavy ceramic industry in Galicia (NW Spain)

The heavy ceramic industry (building materials and refractory products manufacture) is an important source of pollutants to the environment. For this reason these industrial sub-sectors are included in prevention and control pollution policies, specifically those of the European Union. The IPPC Directive pays particular attention to the mineral industries, not least to the ceramic industry (epigraph 3.5, Annex I). In this paper, a methodology which is being applied to support IPPC installations and the competent administrative authority in Galicia (NW Spain) is presented. For that, the Galician heavy ceramic industry is analysed, as also are the ways to study the Best Available Techniques (BAT) with a view to establishing the emission limit values (ELV) for each specific case. Hence, a technological state of the art has been carried out for both sub-sectors, from the point of view of implementation of the IPPC in Galicia. Following this, the processes are described briefly and an analysis of the consumption and emission levels of the main pollutants is made. An inventory that includes the best environmental practices and the preventive and abatement candidate techniques as BAT was elaborated for both considered sub-sectors. An information data sheet for each candidate BAT is presented as a method to help both the industries and the competent authority to identify a candidate technique of the inventory as BAT. Three illustrative examples of the application of this procedure are presented for different emissions to environmental media for Galician installations.     

Landfill design: need for improvement of water and soil protection requirements in EU Landfill Directive

This paper deals with environmental policy issues related to a landfill design. The final product of numerous waste treatments should be placed on a landfill. Before waste disposal, the ground should be protected by a mineral layer with properties required by the related regulation. In order to prevent environment pollution, EU adopted the Landfill Directive 1999/31/EC. The most important technical requirements related to the characteristics of the layer material are water permeability and thickness. The performed comparative national regulatory analysis raised the question of the need for more uniform elaboration of the directive requirements over the whole European Union area (including EU candidates). The choice of the material for the impermeable mineral layer, which should be made during landfill design, is a very important decision. Methods for the determination of the permeability coefficient were analysed, showing that the Directive should define hydraulic gradient as a physical quantity and define its value through measurement of the permeability coefficient. The paper analyses whether some parts of the Directive, as landfill design BAT and base for national legislative acts, require further elaboration in order to provide sufficient information about proper protection of soil and water. Using integrated approach, seven amendments on the directive annex I were suggested related to (a) the meaning of the term artificially established geological barrier, (b) layer thickness, (c) water permeability coefficient determination, (d) mineral layer lifecycle, (e) the meaning of the term sealing and (f) leaching control of material joints.     

The revision of the air quality legislation in the european union related to ground-level ozone

Complying with the obligation in the current ozone directive, the European Commission came forward in 1999 with a strategy to combat tropospheric ozone together with a proposed revision of the air quality legislation for this pollutant. As a daughter legislation under the 1996 Framework Directive on Air Quality, the proposed ozone daughter directive defines for the first time (interim) air quality targets for ozone to be attained by 2010, complemented by long-term objectives for ozone based on the guideline values of the World Health Organisation. It also sets out enhanced requirements for monitoring and assessment of ozone concentrations, as well as minimum criteria for appropriate information of the public about the measured air pollution.In the past, abatement strategies against air pollution consisted of concrete obligations for controlling emissions derived solely on the basis of technical and economic aspects, covering specific types of installations or activities, thus with no direct quantitative relationship to the level of air pollution let alone to its effects.In compensating this deficit, the Commission presented, as a complement to the existing sectoral legislation, a proposal for a directive on national emission ceilings (NEC) which quantifies emission targets for every Member State to bring its total precursor emissions by 2010 down to levels being considered as necessary to achieve everywhere on a regional scale the air quality targets set in the ozone daughter directive.As the core element of the ozone abatement strategy, the national ceilings for emissions of sulfur dioxide (SO(2)), nitrogen oxides (NO(x)), ammonia (NH(3)) and volatile organic compounds (VOC) were derived from a cost-effectiveness analysis integrating information on economic, technical, physical and biological aspects of ozone pollution and abatement. This integrated assessment considers the potential and costs for further emission control in the various economic sectors in the Member States and combines this with information on ozone formation and transport processes in the atmosphere and with indicators for the impact of ozone on human health and environmental. Reflecting the discussions with Member States and stakeholders, a number of decisive steps in the process of deriving the national emission ceilings are presented here: the way of framing interim objectives, how to choose an appropriate ambition level, aspects of how to cope with uncertainties in the model and the input data and how to treat extreme meteorological situations and resolve problems in the spatial distribution of the interim objectives given the different size of countries. Finally, the paper explains the scenario underpinning the proposed national emission ceilings, its environmental gains and the distribution of cost incurring for emission control measures in Member States.     

IPPC, BAT, and voluntary agreements

It is argued that the current discussion on Best Available Techniques (BAT) may not foster true sustainable production. Other instruments from the Integrated Pollution Prevention and Control (IPPC) Directive, such as reporting, may be more effective in this respect. The Irish Integrated Pollution Control (IPC) system has operated for more than 5 years. Its emphasis is on prevention, environmental management systems (EMS), and reporting. Initial results are encouraging. In this paper, the system is used as a case study to illustrate the potential power of the Directive.EMS, if solely voluntary, may be less than effective. It is thus argued that the regulator can become involved in the process - so that EMS can be 'guided'.     

Some aspects on radiation protection in conventional and digital radiology in Romania

Since 1965, medical radiation exposure in the population of Romania has been evaluated by the Network of Radiation Hygiene Laboratories of the Ministry of Public Health, including 23 laboratories throughout the whole country; the network is co-ordinated by the Institute of Public Health Bucharest. In Romania, for a population of 22.5 million inhabitants, 465 X-ray examinations were reported during the last survey, the most frequent being chest examination. There was no specific reference to digital radiology. Digital radiology has been introduced only recently in Romania, and only some rough data on the situation can be presented. Siemens AG is now present in Romania with 23 installations, type SIEREGRAPH CF and AXIOM ICONOS. A digital image intensifier technique is used only for fluoroscopy, and radiography is performed using a conventional film/screen combination. The company Philips has nine installations for angiography, model INTEGRIS, and uses a computed radiography technique. Several direct digital radiography MULTISYSTEM SWISSRAY installations (about 40 units) are also available for adult and paediatric examinations. The Council Directive 97/43/EURATOM on health protection of individuals against dangers of ionising radiation in relation to medical exposure was fully transformed into Romanian legislation in 2002.     

The special severity of occupational accidents in the afternoon: "the lunch effect"

The severity of occupational accidents suffered by construction workers at different hours of the day is analyzed in this study. It may be seen that the interval of time between 13:00 and 17:00 has incomprehensibly high rates of severe and fatal accidents in comparison with any other. We associate this higher accident rate with what we have termed the “lunch effect”. We studied 10,239,303 labor accidents in Spain over the period 1990–2002. The relationships between potential risk factors for occupational accidents around lunch in Spain, especially alcohol consumption are studied, using two methods: analysis of national archival data of 2,155,954 occupational accidents suffered by workers in the construction sector over the period 1990–2002 and a survey study. This study also seeks to contribute the opinions of the workers themselves regarding the causes that might explain this situation.     

Selection and implementation of pollution prevention techniques in small and medium enterprises in countries in transition

This paper aims to open the discussion about the possibility and economic feasibility of applying pollution prevention techniques in industrial enterprises with smaller production capacities than those specified in Directive 2010/75/EU. The work refers to countries with transition economies where low cost of environmental resources and pollution fees are present. The research is conducted on pilot sample of seven small- and medium-size enterprises belonging to the food and beverage sector. The enterprises have different characteristics in terms of company size, capacity levels, production processes employed, and status of the transition in terms of their ownership status. The selection of appropriate prevention techniques is done using newly developed Method for Identification of Prevention Techniques (“MIP”). The MIP method combines: (i) Minimization Opportunities Environmental Diagnosis methodology developed by Regional Activity Center for Sustainable Consumption and Production Barcelona and its approach to data collection, (ii) United Nation Industrial Development Organisation’s step-by-step approach to environmental diagnosis of industrial enterprises, (iii) Driving Forces, Pressure, State, Impact, Response Framework used by European Environmental Agency to facilitate problem–solution identification, (iv) Multicriteria ranking method for selection of best available techniques, and (v) Philosophy of Shewhart–Deming’s circle to introduce the system of planning, control, and correction and integrate prevention concept into business policy. This provided necessary flexibility corresponding to companies’ abilities to finance implementation. The results confirmed that the pollution prevention concept can be applied to small- and medium-sized companies of different production capacities and organization levels with both environmental and economic benefits.     

Application of the Seveso Directive in France.

First, the paper presents a brief summary of the French actual regulation on installations registered for the protection of the environment and covered by the Seveso I Directive. Then the paper discusses research and development needs for a sound implementation of the Directive, and for the new requirements on safety reports established by the Seveso II Directive. Further, it discusses issues connected with coverage of hazardous activities, learning from accidents, technical and organisational measures (safety management systems and emergency response) and human factors. The conclusions stress the need for networking and dissemination of accident investigations, development of safety management systems, and research on cognitive ergonomics and psychology related to the decision making and interventions of the operator.     

The new EIA Directive (2014/52/EU) and UK water impact assessment practice

This paper considers how impact assessment practice relating to all aspects of the water environment will be affected by the transposition of the amended environmental impact assessment (EIA) Directive (2014/52/EU) into UK legislation. Key elements of the new Directive are identified, such as requirements relating to monitoring, climate change (including adaptation), biodiversity, human health and coordination with Water Framework Directive (2000/60/EC) (WFD) Assessment. The extent to which existing guidance and practice already meet these new requirements is assessed, through a review of relevant guidance and selected environmental statements (ESs). Key areas where water impact assessment (WIA) practice needs to be adapted to take account of the new requirements are identified. Substantial changes in practice are likely to be required to incorporate human health assessment into WIA and to demonstrate that competent experts are used to conduct WIA. New guidance will be needed relating to competent experts and improved guidance will be required for WFD Assessment.     

Accreditation in radiation protection for cardiologists and interventionalists

Training in radiation protection is widely recognised as one of the basic components of optimisation programmes for medical exposures. Occupational and patient radiation risks in interventional radiology can be quite high and international bodies have shown concern on this item. Following recommendations of the International Commission on Radiological Protection and in accordance with the European Directive on medical exposures, some initiatives for training in radiation protection took place in Spain and Luxembourg. These provided practitioners of interventional radiology adequate theoretical and practical training in radiation protection. The main outcome of the pilot courses organised to this end is discussed, concluding its suitability to implement the European Directive in practice.     

Assessing the strategic benefits of distributed generation ownership for DNOs

The potential for distributed generation (DG) to act as an alternative distribution planning option is now well-recognised by academia and industry, and could play a significant role in electricity distribution utility operation and design. However, the unbundling requirements of European Directive 2003/54/EC, coupled with traditional network planning approaches adopted by European distribution network operators (DNOs), appear to be hindering development of DG and its deployment for distribution network ancillary services. The incentives - or otherwise - that arise from alternative models of DG ownership by bundled and unbundled distribution utilities are examined here. The preference for the siting and sizing of DG installations by DNOs is simulated using a multi-year multi-period optimal power flow. Broadly based on the recent UK regulatory framework, the DG ownership issue and its potential to influence DG penetration are explored.     

Evolution of diagnostic reference levels in Spanish intraoral radiology

A total of 16 175 official reports of quality assurance on dental radiodiagnostic surgeries from 16 Spanish autonomous regions compiled during 2002-09 were studied to determine the evolution of diagnostic reference levels (DRLs) for obtaining a diagnostic image in the normal conditions of clinical practice in Spanish dental clinics. A DRL of 3.1 mGy was set in 2009, which represents a 35.4 % decrease compared with the dose determined in 2002 (4.8 mGy). During the same period, the mean dose fell by only 17.2 %. The DRL recommended by the European Union in 2004 for intraoral radiology is 4 mGy, and this study shows that 83.4 % of the installations used a dose below this. Of the installations using indirect or direct digital systems 1.1 and 1.2 %, respectively, used doses higher than those recommended, while 14.2 % of those using radiographic film exceeded this limit.     

Environmental capability: a Bradley–Terry model-based approach to examine the driving factors for sustainable coal-mining environment

Environmental pollution caused due to coal-mining activities distresses the natural biodiversity and hampers sustainable development of coal-mining environment. Based on the environmental impact analysis of coal-mining activities, this study develops a framework for computing the environmental capability considering air pollution reduction, water pollution reduction, noise pollution reduction and land pollution reduction. This study proposes a method for ranking the parameters and subsequently computing their sustainable environmental capability using Bradley–Terry model. The parameters have been ranked by assigning the weights, using attitudinal data collected by surveying the experts from industry and academics. Further, in order to compute the environmental capability of coal mining, these weights have been integrated with the real-life published data collected from environmental reports and journal publications of mining firms for the period 2010–2016 in Dhanbad. The results show that the environmental capability of coal mining has increased by 57–62% during the period under consideration, with the major contribution from air pollution reduction and water pollution reduction. However, in case of noise pollution reduction, it is fluctuating by?±?2–3%, and hence no significant contribution is found. Here, the increasing trend of the environmental capability of coal mining indicates the reduction in environmental pollution which subsequently leads to a sustainable coal-mining environment. This study contributes to this domain of the literature by building an integrated framework which can be used as a tool for environmental impact assessment of coal-mining industry and other industries as well.     

Evaluation of VOC recovery strategies

Many manufactured items receive surface coatings for decoration and/or protection against damage. In a number of places along the production line emissions of (VOC) Volatile Organic Compounds can occur. Because VOC are a major contributor to photochemical smog, control of VOC emissions is a major concern for the industries' commitment to the environment. Approaches for process optimisation have a long tradition within chemical and process engineering for the systematic identification of cost- and resource-efficient production options. The challenge in the context of supply chain management is the optimal recovery and reuse of materials not only for single substances or energy flows in large chemical installations, but also for smaller production processes and various mass and energy flows within and between enterprises. Based on a case study from the industrial coating of bicycle frames, an approach for Multi Objective Pinch Analysis (MOPA) for the evaluation of overall recovery potentials for energy, water and VOC is presented. Moreover, a metric for resource efficiency is introduced as a measure for the possible savings potential and for the savings ultimately realised. This integrated approach requires a tight coupling of mass, energy, economic and environmental assessment methods and demands a highly interdisciplinary approach.

Environmental meso-economics in university curriculum: new master program in environmental technology and management

A new Master Program in environmental technology and management has been developed in the framework of the Swiss-Jordanian cooperation, to ensure sustainable knowledge transfer in environmental management, technology, and economics. The areas represented in this program are cleaner production, hazardous substances management, and meso-economic analysis. All of these areas are under the theme of integrated resources management. The program implementation is carried out at Princess Sumaya University for Technology PSUT through cooperation with universities and environmental organizations in Switzerland, which was started in February 2008. The need for establishing this program in Jordan emerged from the practical experience of the Swiss partners who are working in environmental management. It was found that the concept of integrated resources management and the efficient utilization of resources were under estimated by practitioners. This leads to the urge of establishing a comprehensive program to upgrade the capacity of practitioners and new graduates to be able to handle environmental resources in a sustainable manner. For this purpose, the program includes and promotes the use of a number of tools. Meso-economic analysis is introduced in the program as a suitable tool to reflect the environmental values in monetary perspective, and to fill the gap at a meso (sector level) between the traditional micro (enterprise level) and macro (country level). Thus, meso-analysis comes out with integrated picture about the whole country’s sector and its related environmental damage and remediation options.     

Safety,health or the environment--which comes first?

This paper describes the development and application of two integrated models which can be used for assessing the life cycle risk (to life) and environmental impact of a number of possible concept options for new offshore oil and gas developments. The two models can also be used for ranking the designs in terms of lowest human risk and environmental impact. The paper also gives values/criteria for both risks to safety, health and the environment by which the total safety, health and environmental assessment/impact may be balanced as a whole. The paper illustrates the use of the models and shows that the pragmatic or cosmetic improvement to safety, health or the environment may not be advantageous to the overall safety, health and environmental objectives. While the models were developed originally for offshore installations, the basic framework can be readily adapted for use on onshore petrochemical processes.     

Mechanical characterisation of heat resistant power plant materials by creep and fatigue testing in controlled gas atmospheres

The continuing increase of steam parameters of fossil fuelled high efficiency power plants and new combustion concepts for the capture and storage of carbon dioxide lead to harsher service conditions for the components and structural materials of such facilities. The present work introduces a test concept that allows testing of candidate materials under simultaneous mechanical and corrosive loading. The material's reaction can be directly investigated under simulated temperature, load and corrosion conditions of modern installations. First results obtained for different heat resistant steels suggest a strong influence of the environmental medium on the fatigue and creep behaviour. Such findings complement the data that is available from the classical qualification process of the materials and may support the material selection for new power plant installations.     

Nanotechnology,standards and tools benefit smart materials

US Small Business Innovation Research (SIBR) and Small Business Technology Transfer (STTR) proposals concerning advanced materials and manufacturing systems will be due in June 2002. This month sees the deadline for SBIR/STTR biotechnology and electronics proposals. The SBIR/STTR programme's main push is to transform scientific discovery into social benefits and to emphasize private sector commercialization, so proposals must identify the beneficiaries of the technology and its potential for commercialisation. Those who succeed will conduct R&D on projects that result in near term application of product, process or device concepts or enhance the ability of scientists and engineers to conduct fundamental or applied research.     

Retrospective dosimetry: dose evaluation using unheated and heated quartz from a radioactive waste storage building

In the assessment of dose received from a nuclear accident, considerable attention has been paid to retrospective dosimetry using heated materials such as household ceramics and bricks. However, unheated materials such as mortar and concrete are more commonly found in industrial sites and particularly in nuclear installations. These materials contain natural dosemeters such as quartz, which usually is less sensitive than its heated counterpart. The potential of quartz extracted from mortar in a wall of a low-level radioactive-waste storage facility containing distributed sources of 60Co and 137Cs has been investigated. Dose-depth proliles based on small aliquots and single grains from the quartz extracted from the mortar samples are reported here. These are compared with results from heated quartz and polymineral fine grains extracted from an adjacent brick, and the integrated dose recorded by environmental TLDs.     

Environmental licensing and energy policy regulating utility-scale solar photovoltaic installations in Brazil: status and future perspectives

ABSTRACT

Procurement auctions have been the main mechanism to ensure the deployment of utility-scale solar photovoltaic installations (USSPVI) in Brazil. To participate in the auction, investors must comply with all established requirements. In the solar case, the criteria incorporate State environmental licensing regulations (EL). The procurement auctions are a nationwide competition whereas the environmental licensing for those projects are under state jurisdiction. The lack of national guidance to licensing USSPVI might cause significant movement of projects to States whose EL procedures require fewer studies. This work examines the role of environmental licensing in the energy planning for USSPVI in Brazil. Analysing the 27 state regulations establishing the screening requirements that subject EIA to USSPVI, there are uneven threshold criteria to determine whether the plant will go through simplified licensing or regular process. There is also a need for studies tackling strategic environmental assessment for wind and solar expansion in Brazil. Specifically, incorporation of community concerns, public participation, and environmental constraints into the early stages of decision-making to prevent impacts and conflicts.
