Integrated pollution prevention and control in large industrial installations on the basis of best available techniques – The Sevilla Process

With respect to emissions from industry, the IPPC Directive is one of the key instruments of the environmental legislation of the European Union. The purpose of this Directive is to achieve integrated pollution prevention and control from large industrial installations. The conditions of required permits have to be based on Best Available Techniques (BAT). In 1997, the so-called Sevilla Process was established to develop these BAT. Since then, 33 Best Available Techniques REFerence Documents (BREFs) were drafted, adopted and published. This Sevilla Process with its actors is described. The BREFs are unique documents containing ambitious consumption and emission levels which cannot be found anywhere else.     

Adapting the European approach of Best Available Techniques: case studies from Chile and China

Best Available Techniques (BAT) are an essential element in European environmental legislation as required by the Directive on Integrated Pollution Prevention and Control (IPPC 96/61/EG). The technology transfer to industrialising countries, however, requires the adaptation of the underlying criteria, due to differences in economic, legal and technical conditions. Additionally, their prevailing technology standards and different priorities concerning the affected environmental media (air, soil, water) must also be considered. At hand of case studies for VOC emission reduction and prevention for coating applications in Chile, China and Germany, the use of a metric for country-specific determination of BAT is proposed.     

Evaluation of the implementation of best available techniques in IPPC context: an environmental performance indicators approach

In this paper an integrated methodological approach is presented for the evaluation of the implementation of the Best Available Techniques (BAT) in facilities operated under Integrated Prevention Pollution and Control (IPPC) Directive, based on the development and application of a set of sub-indices. An aggregated form of sub-indices that could be used as a composite IPPC facility index is proposed. A sector specific index can be derived from facilities composite indices.This approach uses environmental performance data from European Polluting Emissions Register (EPER) reports, environmental permits and BAT Reference Documents, and gives a coherent and interesting picture of the degree of BAT implementation and an indication of IPPC obligations fulfilment.A specific application is demonstrated concerning the paper manufacturing sector in Greece. It is concluded for this sector that there is a measurable discrepancy from the BAT fulfilment obligations and that the most problematic sub-indices are the “Releases to Water” and “Releases to Air”.     

Environmental profile of textile wet processing in Finland

This study was carried out in major Finnish textile companies in order to create an environmental impact profile for wet processing in Finland as a part of drafting the Best Available Technique (BAT) Reference documents for the European IPPC Bureau. System boundaries were defined for alternative process technologies to be used in BAT definitions. The use of resources and process emissions is, however, monitored for the whole wet processing only in the companies under study. No remarkable differences in energy and water consumption between continuous and batch wet processing could be measured; the lowest dyeing liquor ratios were reported on jet machines and the highest on winch dyeing machines. Dyestuff consumption depends on the colour shade required; some dyes have, however, low fixation rates, such as reactive and sulphur dyes, only 60% on average. About 20% of the process liquor containing unfixed dyestuffs and auxiliaries end up in sewage treatment plants. These chemicals are not recovered and reused in the companies under study. All industrial plants in Finland discharge their wastewater to municipal sewage treatment plants, which carry out wastewater analysis and control. All textile plants, which use more than 50 tonnes of organic solvents per year, are under official off-gas control in Finland.

Techno-economic assessment of recycling practices of municipal solid wastes in Cyprus

In this study, the application of modern recycling technologies in accordance with the European and Cyprus legislation, aiming at the recovery of paper, glass, plastics, aluminium and non-ferrous metals from municipal solid waste (MSW) is presented. The international situation was reviewed, the general trends are marked and the main recycling practices treatments are reported. The paper presents also an overview of the current practices and their environmental implications in Cyprus, and discusses the design and feasibility of a recycling plant located in Pafos area. Three recycling practices for recyclables that were separated at source, varied by their level of automation (0%, 50%, 100%), have been studied from the technical and economic aspect. It was considered that source segregation of organic part from the MSW takes place and no organic matter reaches the recycling plant. A sensitivity analysis was carried out in order to define the most significant parameters affecting the viability of a recycling scheme. It is proved that a fully automated recycling plant with a capacity of 6 tn/h of recyclables located in the industrial area of Pafos, seems to be conditionally feasible and economically profitable solution.     

A method to improve the international comparability of emission data from industrial installations

Emissions from industrial installations are regulated under several international conventions and directives to prevent harmful impacts on environment and human health. Stricter limitations often exist in national legislations, or due to regional and local conditions, than in the international conventions. The international comparability of emission data from industrial installations is currently poor. Comparability is an essential element when the environmental performance of different installations or techniques is studied, as well as in reviewing data presented in emission registers. The availability of reliable and comparable data is an important requirement for the emissions trading market. Comparable emission data ought to be used when reviewing compliance with the national emission reduction targets established under international conventions, as well as in reviewing the compliance of industrial installations with the requirements set in the environmental permit conditions. There are currently no internationally agreed principles or a comprehensive strategy for production of emission data at the level of an industrial installation.The data production chain principle presented in this paper provides a tool for identifying elements that are essential in comparing emission data correctly and that need to be taken into consideration to ensure emission data reliability. The method was originally developed and applied in Finland for emission and impact monitoring of wastewaters from industrial installations and fisheries. Due to the implementation of the Integrated Pollution Prevention and Control (IPPC) directive the methodology was reconstructed for integrated emissions monitoring purposes. The data production principle was introduced for European use when preparing the BREF document on monitoring of emissions. It will also be relevant when the industrial installations report their emissions data to the Pollutant Release and Transfer Registers (PRTRs).     

Possible steps to follow for filling the gap between requirements and the real condition in tanneries

The tannery industry, as one of most important industrial activities, faced more dilemmas at the fall of communistic era:

• -Can the branch keep a leading position for the exported products at the national level, under a de-centralized system?
• -Can the industry comply with the new, more stringent environmental legislation?
• -How far is this industrial branch from the European BAT/BATNEC?

Facing a completely new perspective for their development, many industrial units had a limited margin for manoeuvre and those not enough flexible had to shut down.“Economic survival whatever the price” has been the mantra for some good years. The newly presented EU legislation has been raising many difficult and complex problems for the units that managed to survive that they need to prioritize their improvement actions.Combining Cleaner Production (CP) measures with laboratory research for technology upgrades can have a synergistic effect for improving environmental performance and decrease resource consumption. The effects were evaluated for more experimented measures, such as better process control, toxics use reduction, and source separation of wastes. The results demonstrate that real improvements of environmental performance can be achieved and the indicators that were utilized have values that are comparable with those published for “advanced” processes practiced in EU.     

Mapping of environmental and technological performance of food and beverage sector in Bosnia and Herzegovina

The objective of this paper is to discuss the mapping methodology implemented in the selection of BAT candidates and to present the results of the mapping of B&H food and beverage sector, prepared as a baseline for the development of national reference documents on Best Available Techniques. The subsectors subject to analysis were: dairy, fish farming, fish processing, fruit and vegetable processing, meat processing, breweries, and slaughterhouses.The sector was mapped from several aspects, including socio-economic, legal, and environmental point of view. The socio-economic aspect focused on understanding the sector’s structure and financial capabilities, pricing for water, energy, and solid waste consumption, as well as employee profiles, in order to better assess the sustainability of decisions taken. Legal mapping focused on relevant regulations, including policies from the following sectors: environment, water use and protection, food safety, agriculture, and veterinary, in order to determine legal requirements from an environmental protection aspect set in the various sector policies. Environmental performance indicators were calculated in order to assess present resource efficiencies and relevant environmental impacts. In addition, the mapping process also addressed the existing level of BAT implementation in the subsectors under consideration.The paper presents a rationale for methodology selection, offers a review of the mapping methodology used, discusses mapping results and provides conclusions in regards to that methodology used and discusses issues that need to be considered in the selection of BAT candidates.     

Emergy,nutrients balance,and economic assessment of soybean production and industrialization in Brazil

The aim of this paper is to evaluate the soybean production and industrial processing stages in Brazil using the emergy accounting methodology and economic cost and revenue estimation in order to assess the environmental and economic inputs to the soybean chain and to evaluate the amount of emergy and nutrients exported to European countries. The main findings of this work were that the agricultural stage uses the highest amount of resources. The emergy exchange ratio shows that farmers are delivering around six times more emergy in the soybean that is being sold than the emergy they are receiving with the money paid for it. Results demonstrate that producing raw soybean and soy meal for international markets makes Brazil lose a great amount of emergy and nutrients. Besides that, soybean production is nowadays providing low profitability to farmers because of low prices for soybean products and high prices for the chemicals used in soybean farming. Therefore, at present conditions, exporting soybean as a commodity results in low profit per unit of area.     

我国燃煤电厂大气汞控制技术综合评估与对策探讨

采用模糊综合评价法与层次分析法或专家判定法相结合,对我国燃煤电厂非常规污染物大气汞控制技术进行了综合评估,以筛选出最佳控制技术.建立了环境、经济和技术为一级指标的三层指标体系,共22个评价指标;初步筛选出洗选煤+烟气净化协同脱除技术、烟气净化协同脱除技术、烟气净化协同脱除技术+活性炭吸附技术等七项技术及技术组合并对其开展评估.结果表明:强调环境因素的层次分析法综合评估结果表明,超低排放协同脱除技术+活性炭吸附技术得分最高（0.797 0）,为最佳控制技术.而专家判定法与强调经济因素的层次分析法的综合评估结果一致,洗选煤+烟气净化协同脱除技术最具经济优势,是专家认可的最佳可用技术（BAT）和最佳环境实践（BEP）.研究显示,我国现阶段可采用洗选煤+超低排放协同脱除技术对燃煤电厂的大气汞污染进行控制,但为达到发达国家的严格排放标准,必须采用超低排放协同脱除技术+活性炭吸附技术.      

农业文化遗产地“三产”融合度评价——以云南红河哈尼稻作梯田系统为例

工业化和城市化过程中,城乡经济差距日益拉大,农村衰落已成为城市化过程中各国面临的共同问题。2015年中央政府提出了“农村一二三产业融合发展”推动农村经济发展的政策,引起了众多学科研究者从不同角度开展研究,但相关研究多以理论探讨为主。农业文化遗产地作为一个以遗产保护为前提的特殊农村地区,如何推动一二三产业（下称“三产”）融合发展,如何量化“三产”融合度,研究尚待深入。基于对农业文化遗产特点、资源特征以及农业文化遗产保护要求等方面的分析,阐释了农业文化遗产地“三产”融合发展的概念和内涵,并构建了由产业融合度与劳动力融合度组成的农业文化遗产地“三产”融合度评价方法体系及具体核算方法。以云南红河哈尼稻作梯田系统十大片区所在的8个乡镇为对象进行评价,结果表明,产业融合度分项指数间越均衡则产业融合度越高;各乡镇分项指数和产业融合度的数值皆很小,有巨大的“三产”融合发展空间;新街镇一二三产业的劳动力融合度领先,其中第三产业贡献率最大;农业文化遗产地“三产”的产业融合与劳动力融合有较高的正相关性（r=0.67）,显著水平在10%以下（P=0.069<0.1）。推动“三产”融合发展可以有效促进农民在本地就业,对于保护农业文化遗产有着重要意义。     

EU COST Action 628: life cycle assessment (LCA) of textile products,eco-efficiency and definition of best available technology (BAT) of textile processing

The COST Action 628 was established to produce first hand, industrial environmental data of textiles in Europe, as well as to suggest tools for comparisons of present technologies and practices with cleaner applications, including the economic effects. The Action network also suggested criteria for ISO (Type III) Environmental Product Declaration (EPD) standards. It was concluded that new emerging cleaner technologies are in a key position when striving towards zero emissions in textile processing. It is also important to identify the most polluting stages of textile processing, with the help of life cycle assessment methodology, in order to focus the development of new technologies correctly. LCA was used to set up criteria for an Environmental Product Declaration for textile products. Unique, first hand industrial data were collected from five European textile industries.     

基于物质平衡模型的工业汞污染防治环境经济手段分析

我国以行政命令手段为主的环境管理措施并不能完全有效控制环境汞污染,因而有必要引入环境经济手段。本文基于汞在采掘、冶炼和产品生产三个生产环节中的利用、处置与排放特征,构建了经济系统及行业部门的汞物质平衡模型,并发现,单个污染源的汞污染物治理难以保证消除汞的环境危害。因而,采取环境经济手段控制工业汞污染,尽可能少的向环境中排放汞,在涉汞工业系统的层面上提高汞的利用效率和再资源化率。我国工业汞污染防治的环境经济手段包括环境污染价格、税费以及绿色金融两大类,但仅对生产环节高浓度汞排放发挥作用,对于堆存、再提取和处置环节的汞排放则作用不大。对此,应从扩大环境税(排污费)的征收范围,建立长效的绿色金融机制和推进第三方治理低含量含汞废物,这三个方面加以改进。     

中国省域尺度下产业结构多维度特征及演化对碳排放的影响

在中国转向高质量发展及2030年前达到碳排放峰值的背景下,寻找保证经济增长的低碳减排途径是学界研究的热点。利用中国2005—2017年省域面板数据,建立SAR模型,并按八大经济区分别构建PECM模型,研究中国省域尺度下产业结构多维度特征及演化对碳排放的影响,主要结论如下：（1）中国省域碳排放具有显著的时滞性和空间溢出效应。（2）全国视角下,产业结构合理化水平提升对碳排放呈抑制作用,且存在负向空间溢出效应;而产业结构高度化对碳排放呈促进作用,且存在正向空间溢出效应,总体上处于“倒U型”曲线左侧。（3）八大经济区视角下,随着经济发展水平的提高,产业结构合理化水平提升总体上能够抑制碳排放,而产业结构高度化水平提升则呈现明显的“倒U型”趋势特征,具有两面性,发达地区呈现抑制效应,欠发达地区则相反;当前处于“倒U型”曲线右侧的区域多为发达地区。因此,由产业结构高度化提升导致碳排放量的增加依然属于中国多数省份当前发展的固有阶段性特征,而产业结构合理化提升在总体上能够拉动碳排放峰值前移,促使碳排放早日达峰。欠发达地区不应以增大三产份额为目标,盲目推动产业结构高度化水平提升,这将很有可能对区域经济发展产生负面影响;而产业结构合理化水平提升是既能够适应中国多数省份当前发展惯性,同时又能促进减排或排放降速的有效途径。     

The IPPC directive and technique qualification at offshore oil and gas installations

The Integrated Pollution Prevention and Control (IPPC 2008/1/EC) directive emphasises the use of a permit system to protect the environment as a whole from unwanted emissions in the specified industrial activities. The directive advocates the implementation of Best Available Techniques (BAT). Today, it is essential to select appropriate techniques, especially when an operating company is functioning in an environmentally sensitive area. On these grounds, companies encounter challenges to fulfill the IPPC guidelines as well as to qualify techniques for a specific purpose. The situation is challenging when applying new techniques or in the case of where a technique is considered new. However, technique qualification provides the evidence that BATs function within specific limits for an intended use whilst delivering an acceptable level of confidence. This paper explains how the concept of the Best Qualified Techniques (BQTs) is implemented using BAT approach. It also discusses a framework for broadening the BAT concept to include BQTs, drawing upon case studies of the offshore oil and gas industry.

Capturing market impacts of farm level policies: a statistical extrapolation approach using biophysical characteristics and farm resources

Technical change at the farm level or changes in input prices often have an impact on the firm's supply function, which in turn affect their economic and environmental performance. These changes can take place in numerous ways. This paper presents a methodology that increases the consistency of supply responses across various sets of agricultural products and most representative farm typologies in Europe, with a market model based on a statistical response function approach. Since most farm simulation models are limited to a subset of regions and farm types, the linkage to an aggregated model requires a procedure for expanding these results to non-sample regions to achieve full regional coverage. This paper addresses theoretical aspects related to the consistency between micro and market level models. The proposed approach is applied using a consistent set of simulation results from farm models in seven European regions. Our results show a fairly stable behaviour of the farm models considered for the analysis and quite good fit of the estimated response surface. As results are still preliminary we critically reflect on the applicability of this method in addressing further needs on up-scaling of other economic as well as environmental indicators.     

Modelling scenarios towards a sustainable use of natural resources in Europe

Issues related to the unsustainable use of natural resources are currently high on the policy agenda both in Europe and in other world regions. A large number of studies assessed past developments of material use and resource productivities. However, little effort has so far been devoted to forecasting future patterns of natural resource use and to provide ex-ante assessments of environmental and economic effects of different resource policies. This paper presents results from the international research project “MOSUS” (Modelling opportunities and limits for restructuring Europe towards sustainability), which was designed to fill some of these research gaps. In this project, a global economy–energy model system was extended by a worldwide database on material inputs, in order to run three scenarios for European development up to the year 2020: a baseline scenario without additional policy intervention and two so-called “sustainability scenarios”, simulating the implementation of six packages of policy measures geared towards decoupling economic activity from material and energy throughput. These measures included, amongst others, taxes on CO₂ emissions and transport, measures to increase metal recycling rates, and a consulting programme to raise material productivity of industrial production. This paper presents the evaluation of the three scenarios with regard to the extraction of natural resources on the European and global level. In the baseline scenario, used domestic extraction within the EU remains roughly constant until 2020, while unused domestic extraction decreases (particularly overburden from mining activities). The stabilisation of domestic extraction, however, is accompanied by growing imports of material intensive products. This indicates that the material requirements of the European economy will increasingly be met through imports from other world regions, causing shifts of environmental pressures related to material extraction and processing away from Europe towards resource-rich countries. The implementation of the six sustainability policy measures applied in the sustainability scenarios results in a slight absolute reduction of domestic extraction in all European countries and significantly increased resource productivities. The results suggest that policy instruments aimed at raising eco-efficiency on the micro level can be conducive to economic growth. To limit rebound effects on the macro level, these instruments must, however, be accompanied by other policies influencing the prices of energy and materials. With regard to global resource use trends, the baseline scenario forecasts a significant growth of resource extraction, particularly in developing countries, reflecting the growing demand for natural resources of emerging economies such as China and India.
