6 European Policies for Waste Management Ingo F. W. Romey and Marc Obladen University of Essen, Essen, Germany 1 INTRODUCTION With the treaty establishing the European Community and with the ratification of the Treaty of Amsterdam, the European Community receives wide legislative rights. The following states are members of the European Community: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxem- bourg, Netherlands, Portugal, Spain, Sweden, and the United Kingdom of Great Britain and Northern Ireland. In order to carry out their tasks and in accordance with the provisions of this treaty, the European Parliament, acting jointly with the Council and the Commission, make regulations and issue directives, take decisions, and make recommendations or deliver opinions. A regulation shall have general application. It shall be binding in its entirety and directly applicable in all Member States. Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. A directive shall be binding, as to the result to be achieved, upon each Member State to which it is addressed, but shall leave to the national authorities the choice of form and methods. A decision shall be binding in its entirety upon those to whom it is addressed. Recommendations and opinions shall have no binding force. By the Treaty of Amsterdam the members of the European Community are obligated to pursue a common environmental policy. Community policy on the environment shall contribute to pursuit of the following objectives: Preserving, protecting, and improving the quality of the environment Protecting human health Prudent and rational utilization of natural resources Promoting measures at the international level to deal with regional or worldwide environmental problems Further Community policy on the environment shall aim at a high level of protection, taking into account the diversity of situations in the various regions of the Community. It shall be based on the precautionary principle and on the principles that preventive action should be taken, that environmental damage should as a priority be rectified at the source, and that the polluter should pay. In this context, harmonization measures answering environmental protection re- quirements shall include, where appropriate, a safeguard clause allowing Member States to take provisional measures, for noneconomic environmental reasons, subject to a Community inspection procedure. Without prejudice to certain measures of a Community nature, the Member States shall finance and implement the environment policy. Without prejudice to the principle that the polluter should pay, if a measure based on the provisions of paragraph 1 involves costs deemed disproportionate for the public authorities of a Member State, the Council shall, in the act adopting that measure, lay down appropriate provisions in the form of temporary derogation, and/or financial support from the Cohesion Fund of the European Community. Exemplary discussed should be the newest and most important decisions dealing with the universal treatment of wastes and the waste management strategy. 2 EUROPEAN DIRECTIVES ON WASTE MANAGEMENT 2.1 European Parliament and Council Directive on Packaging and Packaging Waste The Directive on packaging and packaging waste aims to harmonize national measures concerning the management of packaging and packaging waste in order, Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. on the one hand, to prevent any impact thereof on the environment of all Member States as well as of third countries or to reduce such impact, thus providing a high level of environmental protection, and, on the other hand, to ensure the function- ing of the internal market and to avoid obstacles to trade and distortion and restriction of competition within the Community. This Directive lays down measures aimed, as a first priority, at preventing the production of packaging waste and, as additional fundamental principles, at reusing packaging, at recycl- ing and other forms of recovering packaging waste and, hence, at reducing the final disposal of such waste. It covers all packaging placed on the market in the Community and all packaging waste, whether it is used or released at industrial, commercial, office, shop, service, household, or any other level, regardless of the material used. This Directive shall apply without prejudice to existing quality requirements for packaging such as those regarding safety, the protection of health and the hygiene of the packed products or to existing transport requirements. In this context, “packaging” shall mean all products made of any materials of any nature to be used for the containment, protection, handling, delivery, and presentation of goods, from raw materials to processed goods, from the producer to the user or the consumer. “Nonreturnable” items used for the same purposes shall also be considered to constitute packaging. Generally recommendable is the prevention of packaging. Therefore it shall be ensured that preventive measures are implemented. Such other measures may consist of national programs or similar actions adopted, if appropriate in consultation with economic operators, and designed to collect and take advantage of the many initiatives taken within Member States as regards prevention. Furthermore, all Member States should encourage reuse systems of packaging, which can be reused in an environmen- tally sound manner, in conformity with the Treaty. In order to comply with the objectives of this Directive, Member States shall take the necessary measures to attain the following targets covering the whole of their territory. No later than five years between 50% as a minimum and 65% as a maximum by weight of the packaging waste will be recovered. Moreover, within this general target, and with the same time limit, between 25% as a minimum and 45% as a maximum by weight of the totality of packaging materials contained in packaging waste will be recycled, with a minimum of 15% by weight for each packaging material. At least no later than 10 years from the date by which this Directive must be implemented in national law, a percentage of packaging waste will be recovered and recycled, which will have to be determined by the Council. Member States shall, where appropriate, encourage the use of materials obtained from recycled packaging waste for the manufacturing of packaging and other products. Member States which have, or will, set programs going beyond the above- mentioned targets and which provide to this effect appropriate capacities for Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. recycling and recovery, are permitted to pursue those targets in the interest of a high level of environmental protection, on condition that these measures avoid distortions of the internal market and do not hinder compliance by other Member States with the Directive. Member States shall take the necessary measures to ensure that systems are set up to provide on the one hand the collection and return of used packaging and packaging waste from the consumer, other final user, or from the waste stream in order to channel it to the most appropriate waste management alternatives. On the other hand, the reuse or recovery including recycling of the packaging and/or packaging waste collected, in order to meet the objectives laid down in this Directive, should be ensured. These systems shall be open to the participation of the economic operators of the sectors concerned and to the participation of the competent public authorities. For waste management, a marking and identification system of waste packaging is essential. Therefore, the Council shall decide no later than two years after the entry into force of this Directive on the marking of packaging. To facilitate collection, reuse, and recovery (including recycling), packaging shall indicate for purposes of its identification and classification by the industry concerned the nature of the packaging material(s) used. To that end, the Commis- sion will specify the numbering and abbreviations on which the identification system is based and shall specify which materials shall be subject to the identification system in accordance with the same procedure. Packaging shall bear the appropriate marking either on the packaging itself or on the label. It shall be clearly visible and easily legible. The marking shall be appropriately durable and lasting, even when the packaging is opened. In addition, the Commission will promote, as appropriate, the preparation of European standards relating to the essential requirements, in particular, the preparation of European standards relating to: Criteria and methodologies for life-cycle analysis of packaging The methods for measuring and verifying the presence of heavy metals and other dangerous substances in the packaging and their release into the environment from packaging and packaging waste Criteria for a minimum content of recycled material in packaging for appropriate types of packaging Criteria for recycling methods Criteria for composting methods compost produced Criteria for the marking of packaging With this Directive it will be ensured that the sum of concentration levels of lead, cadmium, mercury, and hexavalent chromium present in packaging or packaging components shall not exceed the following: Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. 600 ppm by weight in 1998 250 ppm by weight in 1999 100 ppm by weight in 2001 Regarding effective packaging management, European information system should be introduced. Thus, Member States shall take the necessary measures to ensure that databases on packaging and packaging waste are established, where not already in place, on a harmonized basis in order to help Member States and the Commission to monitor the implementation of the objectives set out in this Directive. To this effect, the databases shall provide in particular information on the magnitude, characteristics, and evolution of the packaging and packaging waste flows (including information on the toxicity or danger of packaging materials and components used for their manufacture) at the level of individual Member States. In order to harmonize the characteristics and presentation of the data produced and to make the data of the Member States compatible, Member States shall provide the Commission with their available data in standard formats which shall be adopted by the Commission. Member States shall require all economic operators involved to provide competent authorities with reliable data on their sector. Regarding an information system for users of packaging, Member States shall take measures to ensure that users of packaging, including in particular consumers, obtain the necessary information about: The return, collection, and recovery systems available to them Their role in contributing to reuse, recovery, and recycling of packaging and packaging waste The meaning of markings on packaging existing on the market In pursuance of the objectives and measures referred to in this Directive, Member States shall include in the waste management plans a specific chapter on the management of packaging and packaging waste. Acting on the basis of the relevant provisions of the Treaty, the Council shall adopt economic instruments to promote the implementation of the objectives set by this Directive. In the absence of such measures, the Member States may, in accordance with the principles governing Community environmental policy, inter alia, the polluter pays principle, and the obligations arising out of the Treaty, adopt measures to implement those objectives. At least, this Directive specifies essential requirements on the composition and the reusable and recoverable, including recyclable nature of packaging. Packaging shall be so manufactured that the packaging volume and weight be limited to the minimum adequate amount to maintain the necessary level of safety, hygiene, and acceptance for the packed product and for the consumer. Furthermore, they shall be designed, produced, and commercialized in such a Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. way as to permit reuse or recovery, including recycling, and to minimize im- pact on the environment when packaging waste or residues from packaging waste management operations are disposed of. The manufacturing has to avoid the presence of noxious and other hazardous substances and materials as constit- uents of the packaging material or of any of the packaging components or minimized with regard to their presence in emissions, ash, or leachate when packaging or residues from management operations or packaging waste are incinerated or landfilled. The physical properties and characteristics of the packaging shall enable a number of trips or rotations in normally predictable conditions of use and offer the possibility of processing the used packaging in order to meet health and safety requirements for the workforce. At least, the properties should fulfil the require- ments specific to recoverable packaging when the packaging is no longer reused and thus becomes waste. Furthermore, packaging must be manufactured in such a way as to enable the recycling of a certain percentage by weight of the materials used in the manufacture of marketable products, in compliance with current standards in the Community. The establishment of this percentage may vary, depending on the type of material of which the packaging is composed. Packaging waste processed for the purpose of energy recovery shall have a minimum inferior calorific value to allow optimization of energy recovery. Packaging waste processed for the purpose of composting shall be of such a biodegradable nature that it should not hinder the separate collection and the composting process or activity into which it is introduced, whereas biodegradable packaging waste shall be of such a nature that it is capable of undergoing physical, chemical, thermal, or biological decom- position such that most of the finished compost ultimately decomposes into carbon dioxide, biomass, and water. 2.2 Council Directive on Landfill of Waste The aim of the Directive on landfill of waste is, by way of stringent operational and technical requirements on the waste and landfills, to provide for measures, procedures, and guidance to prevent or reduce as far as possible negative effects on the environment, in particular the pollution of surface water, groundwater, soil, and air, and on the global environment, including the greenhouse effect, as well as any resulting risk to human health, from landfilling of waste, during the whole life cycle of the landfill. In principle, each landfill shall be classified in one of the following classes: Landfill for hazardous waste Landfill for nonhazardous waste Landfill for inert waste Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. Member States shall set up a national strategy for the implementation of the reduction of biodegradable waste going to landfills. This strategy should include measures to achieve the following targets by means of, in particular, recycling, composting, biogas production, or materials/energy recovery. It ensures that long-term biodegradable municipal waste going to landfills must be reduced to 35% of the total amount (by weight) of biodegradable municipal waste produced in 1995. Furthermore, the Directive shall take measures in order that liquid waste, waste which, in the conditions of landfill, is explosive, corrosive, oxidizing, highly flammable, or flammable, as well as hospital and other clini- cal wastes arising from medical or veterinary establishments, are not accepted in a landfill. The landfill permit shall state at least the class of the landfill and the list of defined types and the total quantity of waste which are authorized to be deposited in the landfill. Member States shall take measures to ensure that all of the costs involved in the setting up and operation of a landfill site, including as far as possible the cost of the financial security and the estimated costs of the closure and after-care of the site for a period of at least 30 years shall be covered by the price to be charged by the operator for the disposal of any type of waste in that site. Regarding existing landfill sites, it should be ensured that landfills which have been granted a permit may not continue to operate unless the landfill sites will fulfil the standard of state of the art landfill sites within eight years. The directive sets up general requirements for all classes of landfills. The landfill can be authorized only if the characteristics of the site indicate that the landfill does not pose a serious environmental risk. The location of a landfill must take into consideration the existence of groundwater, coastal water, or nature protection zones in the area, the geological and hydrogeological conditions in the area, as well as the risk of flooding, subsidence, landslides, or avalanches on the site. Therefore the water control and leachate management must control water from precipitations entering into the landfill body, prevent surface water and/or groundwater from entering into the landfilled waste, and collect contaminated water and leachate. Where the geological barrier does not naturally meet the conditions of permeability and thickness, it has to be completed artificially and reinforced by other means giving equivalent protection. An artificially established geological barrier should be no less than 0.5 m thick. Recommended parameters for a check study are ph, TOC, phenols, heavy metals, fluoride, AS, and oil/hydrocarbons. In order to reduce global warming, the methane-containing landfill gas shall be collected from all landfills receiving biodegradable waste and the landfill gas must be treated and used. If the gas collected cannot be used to produce energy, it must be flared. Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. 2.3 European Parliament and Council Directive on Incineration of Waste Having regard to the Treaty establishing the European Community and a proposal of the Commission, the Council of the European Union and the European Parliament adopted a new directive on the incineration of waste in July 1999. In accordance with the principle of subsidiary, it was considered that the objective of reducing emissions from incineration and co-incineration plants cannot be achieved effectively by Member States acting individually. Un- concerted action offers no guarantee of achieving the desired objective, and regarding the need to reduce emissions across the Community, it is more effective to take action at the level of the Community. This Directive confines itself to minimum requirements for incineration and co-incineration plants. The Directive is a consequence of the fifth Environment Action Program: Towards Sustainability—a European Community program of policy and action in relation to the environment and sustainable development which sets as an objective “no exceedance ever of critical loads and levels” of certain pollutants such as nitrogen oxides (NO x ), sulfur dioxide (SO 2 ), heavy metals, and dioxins, while in terms of air quality the objective is that “all people should be effectively protected against recognized health risks from air pollution.” That program further sets as an objective a “90% reduction of dioxin emissions of identified sources by 2005 (1985 level)” and “at least 70% reduction from all pathways of cadmium (Cd), mercury (Hg), and lead (Pb) emissions in 1995.” The purpose of the incineration plants established and operated in accor- dance with this Directive is to reduce the pollution-related risks of waste through a process of thermal treatment, especially oxidation, to reduce the quantity and volume of the waste and to produce residues that can be recycled or disposed of safely. The co-incineration of waste in plants not primarily intended to incinerate waste should not be allowed to cause higher emissions of polluting substances in that part of the exhaust gas volume resulting from such co-incineration and should therefore be subject to appropriate limitations. The aim of this Directive is to prevent or, where that is not practicable, to reduce as far as possible negative effects on the environment, in particular the pollution of air, soil, surface water, and groundwater, and the resulting risks to human health, from the incineration and co-incineration of waste and, to that end, to set up and maintain appropriate operating conditions and emission limit values for waste incineration and co-incineration plants within the Community. Incineration plants shall be operated in order to achieve a level of inciner- ation such that the total organic carbon (TOC) of the slag and bottom ashes is less than 3% or their loss upon ignition is less than 5% of the dry weight of the material. If necessary, appropriate techniques of waste pretreatment shall be used. All incineration plants shall be designed, equipped, built, and operated in such a Copyright 2002 by Marcel Dekker, Inc. All Rights Reserved. way that the gas resulting from the process is raised, after the last injection of combustion air, in a controlled and homogeneous fashion and even under the most unfavorable conditions, to a temperature of at least 850˚C, as measured near the inner wall of the combustion chamber, for at least 2 s. If hazardous wastes with a content of more than 1% of halogenated organic substances, expressed as chlorine, are incinerated, the temperature has to be raised to at least 1100˚C. Any heat generated by the incineration or co-incineration process shall be recovered as far as possible. The directive determines following air emission limit values. 2.3.1 Air Emission Limit Values Daily average values: Total dust 10 mg/m 3 Gaseous and vaporous organic substances, expressed as total organic carbon 10 mg/m 3 Hydrogen chloride (HCl) 10 mg/m 3 Hydrogen fluoride (HF) 1 mg/m 3 Sulfur dioxide (SO 2 ) 50 mg/m 3 Nitrogen monoxide (NO) and nitrogen dioxide (NO 2 ), expressed as nitrogen dioxide for existing incineration plants with a capacity exceeding 3 tonnes per hour or new incineration plants 200 mg/m 3 Nitrogen monoxide (NO) and nitrogen dioxide (NO 2 ), expressed as nitrogen dioxide for existing incineration plants with a capacity of 3 tonnes per hour or less 400 mg/m 3 Until 1 January 2007, the emission limit value for NO x does not apply to plants incinerating hazardous waste only.
