Due to the increasing pressure from the European Union, in the last decade the waste management landscape in Greece has been going through drastic changes, especially regarding policies and legislation. Shifts in management practices, however, have been considerably slower. A major component of this shift is the requirement by the Landfill Directive (LD) to divert increasing quantities of biodegradable municipal waste (BMW) from landfilling. Making use of the four-year extension allowed to countries heavily reliant on landfills, Greece will have to achieve the LD diversion targets in the period 2010–2020. In this paper the main aspects of the LD are outlined and critically placed in the context of the EU waste policy and the priorities of the new Waste Directive. The current state of waste management in Greece is presented with the main planning for new BMW treatment infrastructure. The complex and multifaceted barriers to successful implementation of waste policies in Greece are discussed using the case study of the LD, in an effort to draw lessons for the New Member States.  相似文献

Abstract

The transport phase is an often neglected element in the risk assessment of non-nuclear hazardous waste life cycles. Data on special and hazardous waste movements are difficult to acquire, but information collected by the London Waste Regulation Authority during the 1980s gives details of waste consignments from cradle to grave, including U.K. grid references for waste producer and disposal sites. A GIS was used to model the routing of aqueous waste cargoes and assess the potential impacts of such movements. Deficiencies in the consignment records required many assumptions to be made and various scenarios were explored. Roads predicted to see passage of these wastes, together with the estimated levels of tanker traffic, were integrated with the distribution of population, groundwater vulnerability and accident probabilities to evaluate the transportation risks for different localities. Comparisons and evaluations of the implications of different routing scenarios across the study region were made.  相似文献

In this article I consider the initial period of solid waste management planning in the US state of Hawaii. The State encountered a number of economic and ecological controversies during its solid waste management planning, a process that was prompted by the US Environmental Protection Agency. Some issues, like project financing, were common across the US, while others, such as the potential of waste materials to reduce reliance on imported food and materials, were more unique to Hawaii. The controversies from this initial planning period were never quite fully resolved; as they lingered, they were interpreted differently across the Islands. Based on a close reading of government, advocacy group, waste industry and news media documents, I examine the controversies over solid waste management of the time and consider how the ‘dual nature’ of waste in Hawaii—simultaneously an ecological threat and (potential) economic input—shaped the adoption of solid waste management systems there. This article adds to an expanding literature examining infrastructure in environmental and technology histories.  相似文献

State environmental protection agencies are being forced to assume more responsibility for solid waste management. Ohio took the lead in mandating the state control of waste by implementing a statewide, integrated solid waste management plan. This paper discusses the shift in management responsibility and key factors affecting variations in the amounts of waste managed by Ohio's 48 solid waste management districts. Accessibility, population characteristics, location, and open landfill availability are factors that influence managed volumes of solid waste.  相似文献

浙江省经济增长与环境质量演进关系的实证研究   总被引:4,自引:0,他引:4  
基于浙江省1981-2006年的环境与经济数据,运用三次环境库兹涅茨模型对工业"三废"排放量与经济发展的关系进行模拟,研究发现浙江省工业"三废"排放与经济发展之间的关系不完全符合典型的"倒U"型的库兹涅茨特征,而是呈N型波动或同步关系。其中,工业废水排放量的EKC呈"U+倒U"型曲线组合得到的"倒N"型,工业固体废弃物产生量的EKC呈"倒U+U"型曲线组合得到的N型,工业废气排放量的EKC与经济发展关系呈同步关系,目前这些曲线尚未达到转折点,仍处于上升期,表明浙江省目前还未进入工业化后期,仍处于由中期向后期转变的过程中,并据此提出了浙江省实现经济发展与环境保护双赢目标的政策建议。  相似文献

根据环境库兹涅茨曲线假说,选取1991—2007年宁夏经济与环境数据,建立经济发展与工业"三废"排放量以及生活污水排放量的计量模型,分析它们的环境库兹涅茨曲线特征及其成因。研究发现,宁夏工业废水排放量的环境库兹涅茨曲线呈"U"形曲线,工业废气和固体废弃物排放量的环境库兹涅茨曲线均呈倒"N"形曲线,第一次下降的拐点分别出现在2015年和2007年,生活污水排放量的环境库兹涅茨曲线呈正"N"型。结果表明,宁夏工业废水、废气以及生活污水排放量随着经济的发展仍处于上升期,环境污染物排放量EKC的转折点尚未达到。参照发达国家经验,同时结合宁夏"十二五"规划,预计到2020年宁夏人均GDP达到10 000美元时,工业废气和固体废弃物将出现EKC的拐点,工业废水排放量和生活废水排放量不能出现拐点。同时,根据污染物和经济发展的分析结果,提出了不同污染物的防治措施及建议。  相似文献

Waste disposal constitutes an acute problem in numerous African cities. One solution could lie in the recycling of the nutrient-rich waste into agriculture taking place in and around cities. Farmers involved in vegetable production around Jos, Nigeria, have developed a sophisticated soil fertility management strategy combining inorganic fertilizers, manure and urban waste ash. This paper: (1) investigates the socio-economic constraints linked to obtaining scarce organic inputs, particularly urban waste ash and the health hazards (particularly heavy metal contamination of soil and crops) caused by using this ash and (2) suggests ways to improve use of this important resource.  相似文献

Municipal Solid Waste (MSW) landfills world-wide are experiencing the consequences of conventional landfilling techniques, whereby anaerobic conditions are created within the landfill waste. Under anaerobic conditions, slow stabilization of the waste mass occurs, producing methane, (an explosive, 'greenhouse' gas) and toxic leachate over long periods of time. As a potential solution, it was demonstrated that the aerobic degradation of MSW within a landfill can significantly increase the rate of waste decomposition and settlement, decrease the production of methane gas, reduce the level of toxic organics in the leachate and decrease quantities of landfill leachate that need treatment. This paper summarizes the successful results of two separate aerobic landfill projects located in Georgia (USA) and discusses the potential economic and environmental impacts to world-wide solid waste management.  相似文献

Hazardous waste is generated in the production of almost all consumer goods, especially those that contain plastic. The United States is the world leader in generating hazardous waste with 214 million tons produced in 1995. The majority of this waste was wastewater generated by the fifty largest generating facilities, disproportionately concentrated along the western Gulf Coast. The largest facilities also treat most of their waste on site, particularly wastewater. Most smaller generators send waste an average of 200 miles for treatment or disposal. Among both citizens and state governments there is resistance to local siting of waste facilties. Local resistance has convinced businesses or government agencies to look elsewhere to site a proposed facility. State efforts to directly control the flow of hazardous waste have not been successful due to court challenges from industry and subsequent decisions that state restrictions violate the Commerce Clause of the U.S. Constitution. Taxes on both in‐state and out‐of‐state waste have proven effective at reducing in‐state waste disposal.  相似文献

上海城市废弃物增长的环境库兹涅茨特征研究   总被引:83,自引:5,他引:78

对上海1978~2000年人均GDP与城市废弃物增长数据的拟合计算表明,上海城区废弃物增长与人均GDP之间存在比较明显的环境库兹涅茨二次曲线特征。理论计算显示:上海城市废弃物环境库兹涅茨曲线的转折点为人均GDP约33441元,对应的城市废弃物达到相应的理论计算峰值约779万吨。上海的人均GDP在2000年已经达到34547元,相应的城市废弃物清运量为741万吨,略为低于理论拟合计算峰值;说明上海城市废弃物增长的演变在2000年前后的一段时期,总体已经处于环境库兹涅茨曲线的理论峰值转折点附近。可以认为,随着上海人均GDP的持续增长,今后一段时期内上海城市废弃物的总量增长会逐步减缓,而建立体现生产者责任的市场调控废弃物管理公共政策,将有利于加快这一趋势。  相似文献

The advantages of centralized environmental policy-making are widely assumed, but a corrective may be overdue. Central government environmental policy limits local policy options in at least three ways: (1) through federal pre-emption imposing solutions on local government; (2) through federal mandating of policy for implementation by subnational government; or (3) through federal disincentives to local adoption of innovative solutions. These constraints are illustrated by policy controlling the disposal of high-level radioactive waste, hazardous waste, and solid waste, respectively. The constraining effect of central environmental policy is felt regardless of whether the formal structure of environmental rule-making and implementation is centralized or decentralized. The analysis suggests the need for greater flexibility and coordination in the geographic structuring of environmental policy-making.  相似文献

ABSTRACT. From the perspective of a human lifetime, the hazards of some nuclear wastes are permanent, so the warnings we place at contaminated nuclear sites must be permanent too. I address questions of how best to provide one hundred centuries of public warning at the first facility for permanent disposal, the Waste Isolation Pilot Plant in New Mexico. Scenarios of intrusion developed to guide the design of warning markers predicted that most of the changes in the area will be social and cultural. Because blatant and permanent markers will increase, not reduce, the probability of inadvertent intrusion, the most appropriate warning is a “landscape of illusion.” Such a landscape needs not permanent surface markers but underground warning devices beneath a soft surface marker. No warning can guarantee deterrence for 10,000 years, however.  相似文献

山东省经济增长与环境污染水平关系的计量研究   总被引:1,自引:0,他引:1  
以经济增长与环境污染水平计量模型——环境库兹涅茨曲线(EKC)为理论基础,选取山东省1981年以来经济与环境数据,建立经济增长与环境污染水平的计量模型,通过分析经济因子与环境因子的相互关系,探究山东省经济增长与环境质量的演替轨迹。结果表明:山东省工业废水与工业固体废弃物的EKC呈"倒U形右侧"曲线特征,SO2与烟尘的EKC呈"N形"曲线特征;研究时段内,污染物排放量均已渡过峰值,其后随人均GDP的增长呈下降趋势,但是2002年以来,下降趋势停止并产生波动。分析表明,山东省EKC特征与工业结构变化、环境保护投资、环境政策取向有显著关系。  相似文献

As citizens take on expanded roles in gathering and reporting environmental data, their potential impact may relate to organizational traits. This study sought to understand the relationship through a survey that identified traits and impacts of U.S. volunteer water monitoring programs on natural resource policy and management. A multiple regression model tested the influence of nine traits on an index of impact, addressing eight a priori hypotheses related to natural resource management outcomes. Seven traits were significantly related to impacts. Significant positive relationships included: the objective to address an environmental crisis; an EPA and/or state-approved quality assurance plan; support of external decision makers who may use or benefit from data; larger budget; volunteers playing more roles in the research process. Fewer impacts were expected from programs operating within schools. Understanding these relationships can help guide citizen science programs or other types of citizen engagement efforts.  相似文献
