Implementation of the European IPPC Directive—BAT guidelines for the cement industry in Cyprus

The European Integrated Pollution Prevention and Control (IPPC) Directive 96/61/EC aims to introduce a European-wide system of integrated prevention and control of pollution in order to secure a high level of protection to the environment as a whole. It places obligations on the Member States (MS) to introduce controls that ensure operators comply with the Directive. In this framework, as a part of the implementation process leading to formal accession of Cyprus to the European Union, the National Technical University of Athens has examined all documents related to the Best Available Techniques (BATs) published by Institutes and Organisations, such as the Institute for Prospective Technological Studies in Spain, the Environmental Protection Agency in Ireland, the World Bank Group and the Ministry for the Environment, Planning and Public Works in Greece. A series of guidelines were developed for the application of BATs for 14 categories of the Cypriot industry that fall into the IPPC Directive. The concept of BATs plays a central role in the Directive because it provides a basis for setting Emission Limit Values (ELVs) as well as the principal benchmark for determining the obligations of industrial operators in respect of pollution prevention and control. This paper presents the guidelines for cement manufacture in Cyprus.     

Ghana's salt industry: A neglected sector for economic development?

The case of poverty in the abundance of plenty mostly extant in resource rich countries is also evident along the coast of Ghana. Despite the huge salt production potential of the country’s coast, the renewable resource remains highly untapped as output levels are less than 10% of potential output. Meanwhile many of the indigenes of coastal communities wallow in poverty amidst high levels of unemployment. Findings of this study reveal that key obstacles inhibiting the growth of the sector relates to land acquisition, lack of investment, and low level of technology adoption. The study therefore recommends a mix of strategies aimed at rejuvenating the sector to achieve optimum harnessing of salt deposits. This would help diversify the export markets of Ghana and help her industrialization drive towards achieving an upper-middle income country status in the short-to-medium-term.     

Appreciating the biodiversity of remnant bushland: an ‘architectural’ approach

Tutor in the Department of Geography at the University of Western Australia. In response to the fragmentation and loss of indigenous vegetation caused by the expansion of metropolitan Perth, all levels of government in Western Australia have made some commitment to the preservation of biodiversity. A case for seeing and using vegetation structure as a possible surrogate for biodiversity is presented. The concept and a simple methodology which may be applied without any specialist ecological knowledge or expertise is outlined for the urban developer, engineer, planner, decision maker and educator. The notion that the degree of diversity of the vegetation structure of a banksia woodland remnant may indicate and give a substitute or preliminary measure of biodiversity assists the popular understanding of biodiversity. Such a non-technical yet objective appreciation and measure may prove satisfactory for some conservation purposes, until a detailed professional assessment is made of the plant and animal species in a remnant of native vegetation. It is currently being used by state planning staff in Western Australia for the preliminary assessment of native woodland in areas zoned for urban growth at the metropolitan fringe.     

Rising to the Kyoto challenge: is the response of Canadian industry adequate?

A major weapon in Canada's CO2-emissions reduction arsenal is reliance on moral suasion and voluntary action. In this regard, the Voluntary Challenge and Registry (VCR) program constitutes a major effort to encourage industrial firms to reduce their greenhouse gas emissions. In this paper, we begin by providing a critical review of Canadian climate change policy and Canada's international commitments. We then investigate the effectiveness of Canadian policies by analyzing a survey of industrial firms, examining factors that determine firms' familiarity with, participation in and commitment to the VCR program, and their stated potential to reduce emissions by 2008-2012 (Kyoto's commitment period). Results indicate that voluntary programs are unlikely to make a significant contribution to emissions reduction, with industrial firms indicating that, on average, they plan to reduce emissions by some 1-2% below their 1990 level under the current policy approach, much lower than Canada's 6% reduction target.     

Environmental Impacts of the Emerging Digital Economy: The E-for-Environment E-Commerce?

The Internet-led digital economy is changing both the production and consumption patterns at the global scale. Although great potential exists to harness information technology in general and the Internet in particular and improve the environment, possible negative impacts of e-commerce on the environment should also be considered and dealt with. In this forum, we discuss both the potential positive and negative impacts of e-commerce. Drawing from insights gained from the complexity theory, we also delineate some broad contours for environmental policies in the information age. Given the paradoxical nature of technological innovations, we want to caution the scientific community and policymakers not to treat the Internet as the Holy Grail for environmental salvation.     

Managing Birds and Controlling Aircraft in the Kennedy Airport–Jamaica Bay Wildlife Refuge Complex: The Need for Hard Data and Soft Opinions

During the 1980s, the exponential growth of laughing gull (Larus atricilla) colonies, from 15 to about 7600 nests in 1990, in the Jamaica Bay Wildlife Refuge and a correlated increase in the bird-strike rate at nearby John F. Kennedy International Airport (New York City) led to a controversy between wildlife and airport managers over the elimination of the colonies. In this paper, we review data to evaluate if: (1) the colonies have increased the level of risk to the flying public; (2) on-colony population control would reduce the presence of gulls, and subsequently bird strikes, at the airport; and (3) all on-airport management alternatives have been adequately implemented. Since 1979, most (2987, 87%) of the 3444 bird strikes (number of aircraft struck) were actually bird carcasses found near runways (cause of death unknown but assumed to be bird strikes by definition). Of the 457 pilot-reported strikes (mean = 23 ± 6 aircraft/yr, N= 20 years), 78 (17%) involved laughing gulls. Since a gull-shooting program was initiated on airport property in 1991, over 50,000 adult laughing gulls have been killed and the number of reported bird strikes involving laughing gulls has declined from 6.9 ± 2.9 (1983–1990) to 2.6 ± 1.3 (1991–1998) aircraft/yr; nongull reported bird strikes, however, have more than doubled (6.4 ± 2.6, 1983–1990; 14.9 ± 5.1, 1991–1998). We found no evidence to indicate that on-colony management would yield a reduction of bird strikes at Kennedy Airport. Dietary and mark–recapture studies suggest that 60%–90% of the laughing gulls collected on-airport were either failed breeders and/or nonbreeding birds. We argue that the Jamaica Bay laughing gull colonies, the only ones in New York State, should not be managed at least until all on-airport management alternatives have been properly implemented and demonstrated to be ineffective at reducing bird strikes, including habitat alterations and increasing the capability of the bird control unit to eliminate bird flocks on-airport using nonlethal bird dispersal techniques. Because the gull-shooting program may be resulting in a nonsustainable regional population of laughing gulls (>30% decline), we also recommend that attempts be made to initiate an experimental colony elsewhere on Long Island to determine if colony relocation is a feasible management option.     

Produced natures through the lens of biodiversity conservation and tourism: the Ponta Negra Caiçara in the Atlantic Forest Coast of Brazil

Understanding nature as an outcome of organising discourses generated through relative experiences of our surroundings has been the groundwork of a political ecology that deals with the distribution of environmental justice among people with different degrees of power. In this paper, we examine how the environmental legislation and the tourism industry have constructed the term Caiçara as a way to categorise the inhabitants of the Atlantic Forest Coast of Brazil, in ways that meet their goals, but in turn occludes the discourse of the Caiçara themselves. Ethnographic research conducted in Ponta Negra, a small coastal community located at the heart of the Juatinga Ecological Reserve (Paraty, Rio de Janeiro State), as well as a review of key legislation, management plans and tourism materials form the empirical basis of this research. First, we offer a critical examination of the historical origin of the term Caiçara. We then compare contradictory ideas of Caiçara produced by Brazilian environmental legislation and the tourism industry. While the environmental legislation has characterised the Caiçara as fallen angels who are no longer conservation allies, the tourism industry has profited by selling them as ecologically noble savages who still live in harmony with the environment. Our analysis shows how Ponta Negra people have become objects of powerful discourses of nature that hinder the recognition of their collective rights and weaken their position to negotiate for their own desires and aspirations related to their identity and livelihoods.     

Shaped by race: why “race” still matters in the challenges facing biodiversity conservation in Africa

This article uses experiences from South Africa to argue that, despite progress made in making biodiversity conservation compatible with social, political and economic changes, progress could still be limited by reluctance of social actors to acknowledge and engage with the issue of race. The article argues that acknowledging the history of conservation in Africa, including close ties to racially charged colonialism, could be a positive impetus in the transformation of conservation to make it more socially, economically and politically justifiable.     

Nature as an arena for the quality of life: psycho-spiritual values—the next main focus in nature conservation?

The purpose of this article is to discuss the concept of the psycho-spiritual values of nature, to call for increased research and concern, and to address these values as important among the third generation of environmental problems. The loss of biodiversity and the quality of nature harms the basic psychological interests of man: nature contains beauty and wonders, offers a variety of experiences and challenges, acts as a mental anchor, generates insight and wisdom, and represents a part of the identity of every country. To preserve the quality of nature for the benefit of the human mind and spirit, challenges psychologists, biologists, land-use planners and politicians. Nature as an arena for the quality of life is a topic of utmost concern, for it will impact on future generations.     

The toxic release inventory: Fact or fiction? A case study of the primary aluminum industry

Since 1989 manufacturing facilities across the USA must report toxic chemical emissions to the EPA's toxic release inventory (TRI). Public release of this information and increased public scrutiny are believed to significantly contribute to the over 45% reduction in toxic chemical releases since inception of the program and to growing support for this type of informational regulation instead of traditional command-and-control. However, prior research indicates a tendency to under-report emissions. We find specific evidence of under-reporting of polycyclic aromatic hydrocarbons (PAH) to the TRI by primary aluminum facilities after promulgation of the industry's maximum available control technology (MACT) standard in 1997. We also find evidence of dislocation of emission overseas due to these regulatory requirements. Additionally, changes in energy prices affected aluminum production and further distort reported PAH emissions levels. This suggests the possibility of more widespread under-reporting that is modulated by various factors, including market conditions and new regulations, and which may partially explain the downward trend in TRI emissions. It also suggests that the quality of TRI data may improve once facilities are subject to monitoring of emissions of a TRI listed pollutant due to command-and-control regulation.     

Amsterdam: planning and policy for the ideal city?

Is Amsterdam the “ideal city?” Many of the social, economic, and environmental problems facing Amsterdam are considerably less than those in cities in the USA, and in most cases, Western Europe. Amsterdam, at this moment in history, might be the world's greatest city because of its ability to ensure basic necessities, freedom, and creativity. Tolerance of drugs, sexual freedom, along with the integration of different races helps reduce many of the “social problems” faced by most cities. We have compared, on a per capita basis, differences between Amsterdam/Holland and the USA. The Netherlands is a tiny country, and comparisons are made on a city and per capita numbers at the national level. Our data show that Amsterdam has lower crime, murder, rape, drug usage (cocaine, marijuana), teenage pregnancy, diabetes, obesity, suicide, abortion rates, infant mortality, dependence on fossil fuels, and homelessness, and racial segregation is considerably less. People live longer because of Amsterdam's walkability and bike usage and access to parks. Indeed, the Netherlands leads both Western European and the USA in the proportion of trips made walking and bicycling, with significantly reduced car dependency. Ghettos are nearly non-existent compared with the segregation in the 1940s/1950s. Quality housing is supplied to everyone that gives pride of place compared with the stark, cold, and institutional “projects” provided by the US federal government. Amsterdam leads Western Europe by 35% in social housing, compared with runner-up UK, which has significantly less. The modernism of the 1960s where the poor were warehoused is nearly all gone. People living in Amsterdam seem more tolerant, secure, happier, and healthier compared with citizens in the USA. Great cities provide opportunities for all citizens to enhance their lives and ensure an unrivalled level of freedom. We demonstrate that social and environmental justice are tied together. Amsterdam is by no means perfect, but in comparison with many other democratic industrial cities, it is a far better place for citizens of all races, religions, and incomes.     

Education for sustainability: Are we flunking the future?

When New Jersey's Office of Sustainability was originally established in 1997, it was at first quizzically referred to as the “Office of What?” Now, good people, high purpose, and new name (Sustainable Business Division of the Commerce Commission) have steadily gained respect as skeptics reflected on what the term sustainability can mean to life on earth as we know it in New Jersey and elsewhere. Current rates of growth in population, industrial production, consumerism, and environmental degradation cannot be supported indefinitely by Earth's finite carrying capacity. New ways of thinking, working, and living will be required to change our course of unsustainable human activity both locally and globally. Such a transformation is achievable only through major changes in education. This article contends that the rate, content, and scope of learning required to take a sustainable path in America are not happening. Some ideas for what needs to be done are suggested.© 1999 John Wiley & Sons, Inc.     

Environmental management system vs green specifications: How do they complement each other in the construction industry?

Environmental Management System (EMS) has been one of the important tools for sustainable construction for around two decades. However, many issues concerning sustainable development have not been properly addressed, and there is a need for the introduction of green specifications to advance green performance in construction through contract management. This paper defines green specifications, identifies the reasons for adopting green specifications and highlights the environmental issues that may not be addressed by solely adopting EMS. It also presents the results of a recent survey of practitioners concerning their opinions towards green specifications and possible impacts arising from their adoption. From the results of the survey, a framework for developing green specifications is deemed valuable for the cities striving for sustainability. Interestingly, the level of acceptable changes brought about by green specifications as perceived by different industry stakeholders is found to be unrelated to whether they were from organizations implementing EMS or not.     

A value proposition: Resource recovery from faecal sludge—Can it be the driver for improved sanitation?

There is currently a lack of access to affordable sanitation in urban areas of Sub-Saharan Africa. This study evaluated the potential for resource recovery from innovative faecal sludge treatment processes to generate a profit that could help sustain the sanitation service chain. A total of 242 interviews were conducted in Accra, Ghana; Dakar, Senegal; and Kampala, Uganda to compare markets in different cultural and regional contexts. Products identified to have potential market value include dry sludge as a fuel for combustion, biogas from anaerobic digestion, protein derived from sludge processing as animal feed, sludge as a component in building materials, and sludge as a soil conditioner. The market demand and potential revenue varied from city to city based on factors such as sludge characteristics, existing markets, local and regional industrial sectors, subsidies, and locally available materials. Use as a soil conditioner, which has been the most common end use of treated sludge, was not as profitable as other end uses. These findings should help policy and decision makers of sanitation service provision to design financially viable management systems based on resource recovery options.     

Earthworms: nature’s chemical managers and detoxifying agents in the environment: an innovative study on treatment of toxic wastewaters from the petroleum industry by vermifiltration technology

Earthworms are justifying the beliefs of Great Russian scientist Dr. Anatoly Igonin who said they are????disinfecting, detoxifying, neutralizing, protective and productive??. Studies indicate that some species of earthworms can ??bio-accumulate, biodegrade or bio-transform?? any toxic chemicals including ??heavy metals??, ??organochlorine pesticide??, ??herbicides??, and the lipophilic organic micro-pollutants like ??polycyclic aromatic hydrocarbons?? (PAHs). Worm vermicasts, due to the presence of ??hydrophilic?? groups in the ??lignin contents?? and ??humus??, also provide wonderful sites for ??adsorption?? of heavy metals and chemical pollutants in wastewater. Vermifiltration of wastewater using waste-eater earthworms is a newly conceived novel technology with several economic and environmental advantages. The earthworm??s body and the their ??vermicast?? work as a ??biofilter?? removing BOD₅ by over 90?%, COD by 60?C80?%, TDSS by 90?C95?%, and toxic chemicals and pathogens from wastewater. This was a pioneering work done on an extremely ??toxic wastewater?? from the petroleum industry. It contained mixture of ??aliphatic?? and ??aromatic?? volatile petroleum hydrocarbons (C 10?CC 36) and ??organochlorines?? originating from the cooling liquids, waste engine and gear oil, waste transmission and brake fluid, grease, spilled petrol, and diesel oil. The aliphatic fraction contained cycloalkanes as well as a complex mixture of saturated toxic hydrocarbons. The aromatic fraction mainly consisted of PAHs, which are more toxic and persistent than the aliphatic part. The chemicals of concern were the total petroleum hydrocarbons (TPH), dichloromethane (DCM), dichloroethane (DCE), and t-butyl methyl ether (tBME). The tBME compound has raised global concern recently due to its high mobility and persistence in the environment and possible carcinogenicity. About 1,000 earthworms (species Eisenia fetida) were released in the soil of vermifilter bed. They not only tolerated and survived in the toxic petroleum environment but also bio-filtered and bio-remediated the dark-brown petroleum wastewater with a pungent smell into pale-yellow and odorless water indicating disappearance of all toxic hydrocarbons. The hydrocarbons C 10?CC 14 were reduced by 99.9?%, the C 15?CC 28 by 99.8?%, and the C 29?CC 36 by 99.7?% by earthworms.     

Consuming for the Sake of Others: Whose Interests Count on a Market for Animal-Friendly Products?

Many Europeans are concerned about the living conditions of farm animals because they view animals as beings that possess interests of their own. Against this background the introduction of an animal welfare label is being intensively discussed in Europe. In choosing a market-based instrument to take these concerns into account, normative judgments are made about the formation of preferences, the value system that is implicitly assumed, and the distribution of property rights. From the perspective of classical institutional economics it can be shown that the introduction of a label as an institutional change does not redefine institutions in a way that allows them to consider the interests of animals for their own sake. Rather, the label only redefines the property rights that humans have over animals. The market segregation into privileged and normal animals conflicts with the idea of equality between sentient animals. Within the group of humans only the interests of those who act on markets count. The commodification of their moral concerns assumes that people always decide based on their own interests, which can be traded off. The lexicographical ordering of preferences, which occurs when humans view animals as entities with rights, is not compatible with the normative assumptions of markets. Furthermore, interpreting animal suffering as market failure that can be corrected by labeling impedes a reasoned dialog within the society about the values and beliefs that serve as a basis for preference formation. Thus, an animal welfare label cannot replace a fundamental societal debate about legal standards on animal well-being.     

Managing Endangered Species Within the Use–Preservation Paradox: The Florida Manatee (Trichechus manatus latirostris) as a Tourism Attraction

A significant challenge to wildlife managers in tourism settings is to provide visitors with opportunities to observe rare and endangered wildlife while simultaneously protecting the target species from deleterious impacts. Nearly 100,000 people annually visit Crystal River, Florida, USA to observe and swim with the Florida manatee, an endangered species. This research aimed to investigate and describe human-manatee interactions in a tourism context, to understand the salient issues related to such interactions as identified by stakeholders, and to recommend a course of action to address multiple interests in the planning and management of human-manatee interactions. Five issues were identified by all stakeholder groups: water quality, harassment, density and crowding, education, and enforcement. Currently, the U.S. Fish and Wildlife Service, which is responsible for manatee management, does not have mechanisms in place to manage the tourism component of the manatee encounter. Although a regulatory approach can be taken, a better approach would be to create an organization of tour operators to establish "best practices" that reflect the goal of the managing agency to enhance manatee protection (and thus ensure their livelihood) and to enhance the visitor experience.     

Computer and Electronics Product Stewardship: Are We Ready for the Challenge?

The PC revolution continues to produce faster and smarter machines at a stunning pace. Almost forgotten in the rush are the millions of nearly new, but suddenly outdated, computers that are abandoned every year. Can product stewardship offer life‐after‐end‐of‐life for this growing mountain of “attic‐ware,” while averting a costly—and potentially toxic—waste disposal crisis? © 2001 by Cate Gable, Axioun Books.
