Full textAbstract:
It is, clearly, a Government responsibility to enact laws and promulgate regulations for control of industrial pollution. The main techniques for soil industrial wastes disposal, namely, landfarming and landfilling, profit from the extensive knowledge acquired, in past decades, in the field of water and air pollution control and must be analysed within a comprehensive system for hazardous waste management, with its legal and administrative aspects. This paper presents some general principles of a Hazardous Waste Management System, which are broadly applicable, regardless differences between States or Countries. Finally, it discusses the specific case of Hazardous Wastes Management in the State of Bahia, Brazil and makes some suggestions for its improvement.

Full textAbstract:
Hazardous wastes management in Brazil is a particularly difficult task to accomplish. The country's enormous area, the lack of tradition on dealing with this subject, few trained people, the high investment costs and the sophisticated technology involved make the regional management of hazardous wastes a mandatory approach to reduce costs and maximize benefits. In order to achieve this goal, a synoptic approach over an entire geographical region on all aspects of hazardous wastes management is proposed. On the other hand, several difficulties are foreseen, some of them in the socio-political arena, requiring a lot of an. environmental diplomacy and competent social communication in order to succeed. Despite the difficulties, there seem to be no options to deal with this problem when simultaneously considering its environmental, technical, and economic aspects.

Full textAbstract:
From an environmental viewpoint, the prevailing health problems must be a “first priority” in all major development projects. Public water supply provides only 36% of domestic water. Disinfection of public water supply from the south well field is essential to avoid health problems. About 60% of the drinking water sold by ‘hygienic’ stations is of questionable quality. Expansion and upgrading in hospitals, pharmacies and industries (waste producers) will have an immediate impact on the amount of hazardous waste that will have to be disposed of. To achieve a sustainable urban development and to avoid environment/resources degradation, care should be taken now to monitor and improve handling and management of hazardous waste. Initiating management programs for reducing or preventing the generation of waste during production processes or other operations would be the first step to an economically and environmentally sound way of dealing with hazardous wastes. As complete elimination cannot be realized, ways to recycle the wastes should be sought. Major air pollutants in Sana’a include dust and SPM, carbon monoxide, photochemical oxidants, hydrogen sulfide and ammonia, sulfur oxides and hydrocarbons. The main sources of pollution in the cities are the mobile sources. The emissions of gases from oil consumption are exceeding the permissible level and it is essential that the gases be monitored, at least in the congested areas of the cities. Integration of environmental concerns with economic growth in Yemen should occur at the planning stage, adopting a positive approach and focusing on improvement in the health and welfare of the residents of the program area. Mitigating measures relating to the protection of the urban environment and improving public health must be primary objectives of EIA investigation for any upgrading project within urban areas and any other projects impacting on an urban environment.

Full textAbstract:
This paper presents the current scenario of solid waste management aspects and its challenges in India, which will benefit developing and low-income countries. The leading cause of waste generation is the growing population and the new lifestyle due to the increased per capita income. Consequently, the magnitude of solid waste is continuously growing along with its compositional diversity. In earlier days, the wastes were organic and could be disposed of in low-lying areas conveniently without causing any adverse impact on the environment. But today, the organic fraction of waste has steeply declined while the inorganic portion has increased manifold. Moreover, wastes from industries, hospitals, construction sites, households, and many other sources severely affect the environment and public health. Also, the chemicals generated from the improper disposal of these wastes enter the air, soil, and water resources, causing hazardous and toxic effects in countries that could not implement the adopted policy framework strictly. A state-of-the-art review is conducted in this paper to further search other primary and prevalent reasons behind the inability of proper waste management and to find a real solution.

Full textAbstract:
The purpose of this paper is to review the existing waste management practices, regulatory and institutional framework and technologies that are being employed currently for waste management in Sri Lanka in order to understand the magnitude of non-hazardous and hazardous waste problems and how to avoid these problems. This study is mainly based on information collected from literature review covering both municipal solid waste management and hazardous waste management. Sri Lanka has well-developed legislative and well-organized institutional framework with environmental related policies, strategies and guidelines on waste management. Technologies and methods used for waste management are well accepted, but innovative technologies and strategies have to be introduced to streamline and uplift the existing waste management practices. This study also revealed that there is a high potential in private sector involvement in waste management. Considering all these aspects, a detailed comprehensive technical review and potential technology development are necessary to deal with all categories of wastes generated in Sri Lanka.

Full textAbstract:
AbstractSince the early 1980s different organisations have tried to enact international instruments to control international waste trade. The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal was adopted in 1989 under the auspices of UNEP in order to protect human health and the environment against the adverse effects which may result from the management of waste involved in transboundary movements of hazardous waste and its disposal. The Basel Convention has evolved significantly in eight years-whereas only 35 states and the EC signed the Convention at the time of its adoption, more than 113 states have ratified it as to August 1997. Several other instruments have been developed under the Basel Convention influence. Among those treaties that have been adopted, two deserve special attention. First, the Bamako Convention on the Ban of the Import into Africa and the Control of Transboundary Movement and Management of Hazardous Wastes within Africa adopted in 1991 under the auspices of OAU. Second, the Fourth Lomé Convention adopted by the EC and its member states and 69 African, Caribbean and Pacific (ACP) states. The first part of this article is devoted to a comparative analysis of those three Conventions. The second part of this article gives an objective analysis of the substantive regulation of the Izmir Protocol while criticising diverse aspects and proposing alternatives in view of the conventions treated in the preceding part.

In the current context, significant changes are taking place in the structure of Ukrainian industry. Powerful productions of some spheres of activity lose their urgency and, on the contrary, acquire the development of power of other branches, namely, craft productions, to the composition of which the company belongs. The result of the activity of the businesses complex is the formation of significant volumes of food waste (about 160 thousand ton), discharges of concentrated wastewater, wastewater discharges. The wastes of the restaurant industry have a wide nomenclature and a specific composition, under the conditions of their placement in the components of the environment form the ecological aspects of the negative effects. Food wastes of facility in this branch contain a significant amount of nutrients, organic substances and require complex processes of their processing. Meanwhile, according to their composition, production wastes can be involved in the transfer process with the removal of secondary raw materials and energy sources. Thus, there is a need to improve existing and new technologies for the transfer of hazardous waste in order to reduce the load on the environment. The results of the analysis of world and domestic developments in the field of technologies for the utilization of food waste allowed to determine the main methodological approaches to the transition. In the case of the utilization of food waste, biotechnological methods represent a significant interest. Thus, the work is devoted to the connection of the actual scientific-practical task, which consists in the scientific substantiation and improvement of the technology of the transfer of the population's needs.

AbstractThe development of technology has been increasing rapidly thus almost all aspects of humans are supported by technology and electronic equipment. More electronic wastes are produced, but those could not be managed similar to the conventional wastes and do not have the same characteristics as hazardous wastes as regulated in the Basel Convention 1989 so that the Convention cannot be applied to electronic wastes management optimally. In this present time, there are still no instruments in international law regarding the management of electronic wastes, but the international community has begun to discuss this issue and argue that it is necessary to develop regulations in international and regional levels, especially in the ASEAN region. The analysis and conclusions of this research shows that the Basel Convention cannot optimally accommodate the regulation of electronic wastes management and it is necessary to establish a regulation in the form of a mechanism under the Basel Convention 1989 with regard to environmental aspects. Arrangements at the ASEAN regional level should be made by referring to the principles regulated in the mechanism and formed in a coordinative and non-coercive guideline.

AbstrakTeknologi semakin berkembang hampir semua aspek kehidupan manusia telah didukung oleh teknologi dengan peralatan elektronik. Produksi sampah elektronik semakin banyak, namun mereka tidak dapat dikelola seperti sampah konvensional dan juga tidak sepenuhnya memiliki karakteristik yang sama seperti sampah B3 yang telah diatur dalam Konvensi Basel 1989 sehingga Konvensi tidak dapat diterapkan pada pengelolaan sampah elektronik secara optimal. Saat ini, belum ada instrumen dalam hukum internasional mengenai pengelolaan sampah elektronik, namun masyarakat internasional sudah mulai membahas isu ini dan perlu adanya untuk mengembangkan peraturan di tingkat internasional dan regional, khususnya di ASEAN. Analisis dan kesimpulan penelitian ini memperlihatkan pengaturan dalam Konvensi Basel 1989 tidak dapat mengakomodasi secara optimal mengenai pemanfaatan sampah elektronik sehingga perlu dibuat suatu peraturan berupa mekanisme di bawah Konvensi Basel 1989 dengan memperhatikan aspek-aspek lingkungan. Pengaturan di tingkat regional ASEAN dapat dibuat dengan mengacu pada prinsip-prinsip yang diatur dalam mekanisme tersebut namun dibentuk berupa panduan yang lebih koordinatif dan tidak memaksa.

Full textAbstract:
[Integrative executive summary] NCP Chlorchem (Pty) Ltd manufactures and distributes Chlor alkali products such as chlorine, hydrochloric acid, caustic soda flakes, etc. and in the process generates both hazardous and general waste. Following changes in South African waste management legislation in 2011, the organisation’s waste service provider had to increase the costs associated with the handling of site’s hazardous waste. Top management of NCP Chlorchem (Pty) Ltd requested a meeting with the waste service provider in order to establish the reasons behind the price increase. In that meeting, which the researcher attended, the waste service provider explained the changes in waste legislation and how it was going to impact on their business. Top management understood the reasons behind the price increase; however, they requested the waste service provider to review the price increase. The waste service provider gave the top management of NCP Chlorchem (Pty) Ltd assurance that they were going to discuss the price reduction request with their own senior management and would provide feedback. The researcher did not participate in the feedback meetings; however, to this day, NCP Chlorchem (Pty) Ltd still uses the services of the same waste service provider. The effect the escalating annual waste handling costs has had on NCP Chlorchem (Pty) Ltd’s management team led to the study. Environmental impacts have costs that directly impact on company’s bottom line, such as the costs associated with the generation of waste. Although environmental costs are only one of the many costs incurred by businesses, they deserve management’s attention. According to Jasch (2003), there is an apparent lack of awareness and understanding of the magnitude of the environmental costs generated by organisations, and many opportunities for cost savings through good environmental management are lost. However, using a relatively new tool in environmental management, that is, environmental management accounting (EMA), management would ensure that relevant and significant environmental costs are considered when making business decisions (Jasch, 2003). The main purpose of the thesis is to explore the level of awareness of environmental costs associated with hazardous waste within NCP Chlorchem (Pty) Ltd. In order to carry out the study, literature about environmental and cost accounting as well as literature on waste management was reviewed. Questionnaires were distributed to staff members, and meetings were held with different senior personnel. This case study seeks to answer the following questions: What is NCP Chlorchem (Pty) Ltd’s staff members’ level of understanding of waste management? What is the level of awareness of NCP Chlorchem (Pty) Ltd’s staff of environmental costs with regard to the generation, handling, transportation and disposal of hazardous waste? How can the current traditional accounting within the organisation be integrated with environmental management accounting? The findings of the first research objective revealed that staff members knew the site’s waste streams as per the South African legal definition of waste and as identified in the site’s environmental management system documentation. The conceptual approach to waste management is underpinned by the waste hierarchy. The respondents support the waste hierarchy in its approach to waste management, which is prevention of waste, reduction, reuse, recycle and safe disposal of waste as the last resort. Lack of awareness of environmental management, among other things, was cited as the cause of waste. In addition to that, the respondents believe the waste hierarchy can be achieved by employing recycling facilities, following procedures and by carrying out environmental awareness campaigns. Improving process design and control and including changes in raw material was cited, among other things, as the respondents’ perception on how waste can be reduced. The findings of the respondents’ understanding of waste hierarchy revealed that staff members understood waste management. The respondents cited the impacts of waste on the business as financial impact on the business, impact on their bonuses, and possible loss of business. In relation to the second research objective, it was found that staff members knew the hazardous waste streams and identified amongst other waste, sludge and chlorine emissions as NCP Chlorchem (Pty) Ltd’s hazardous waste. However, with regard to environmental management accounting data, an average of 55.1% of respondents were not familiar with the physical and monetary components of EMA. An average of 19.6% of respondents who were aware of EMA might have been senior personnel. It could further be established that those who were familiar with EMA information were actually working with the data, either for reporting purposes, or for employing waste minimisation strategies, as well as awareness purposes, to their juniors. On average, 80% of the respondents perceived the production department as the area within site that has the EMA information.

Full textAbstract:
The most important thermal, chemical, physical, and biological methods for treating hazardous wastes and the fate of their land-disposed residues are reviewed and evaluated. Technologies are described as major, minor, and emerging according to their stage of development or application to hazardous waste; major ones include rotary kiln, liquid injection, and cement kiln incineration; neutralization, chemical oxidation-reduction, and ion exchange; filtration, distillation and settling techniques; and activated sludge, aerated lagoon, and landfarming treatment. Emerging technologies include molten salt and fluidized- bed combustion, liquid-ion extraction and other processes, none of which are considered to be outside the realm of current or future economic feasibility. In addition, waste reduction strategies and the land burial of stabilized/solidified wastes are discussed. Residues from these technologies vary widely according to waste type and composition, but a common component in many of them is heavy metals, which, as elements, cannot be further degraded to other products. The results of the available literature suggests that these metals will be retained in clay liners beneath a landfill through the mechanism of cation exchange, with the adsorption of metals favored by their smaller hydrated size, lower heat of hydration, and in some cases, higher valences than the naturally occurring alkali earth metals. Other important factors include ionic activity, the pH and ionic strength of the solution, the presence of complexing agents, and the possible surface heterogeneity of the clay. In soils, metal binding through cation exchange with clay is augmented by adsorption onto iron and manganese oxides and complexing with organic matter such as humic acids. Many field studies with landfarmed metal-bearing wastes show that these mechanisms are usually sufficient to retain metals to within several inches of their zone of application.M.S.

Full textAbstract:
The purpose of the project was to determine the effect of various petroleum amendments on the migration rate of Cu. The petroleum amendments used in this research are frequently added to the soil surface in petroleum landfarming. Such petroleum wastes often contain significant amounts of Cu and other metals.Soil columns were amended with citric acid, used crankcase oil and Illinois crude oil. Each amendment was spiked (treated) with three different concentrations of Cu and each treatment was replicated three times. The columns were leached once per week, for ten weeks, with distilled water acidified to pH 4.5 to simulate acid rain. Leachate from the soil columns was analyzed weekly for total Cu. At the end of the ten week period, the soil was analyzed for Cu and TOC content at 7 cm intervals to determine the amount of migration by Cu and the organic amendments, resectively. The soil (a Glynwood silt loam) and the organic amendments were each analyzed for total Cu to determine background levels. The soil was analyzed for pH, TOC, electrical conductivity and soil texture.Analysis of the leachate and soil showed differential migration of Cu through the soil columns. Significant levels of Cu leached in the columns amended with citric acid (as high as 85.3 mg/L) in the first 3 weeks of the study. The Cu content of the leachate from columns amended with crude petroleum were at approximately background levels (5.5 mg/L) as was the leachate from columns amended with crankcase oil (0.2 mg/L). In the later weeks of the research, as the petroleum amendments were broken down by microorganisms, some Cu was chelated to small fragments of the petroleum and leached through the soil columns. Most of the Cu appeared to remain on the surface of the columns, bound to the petroleum amendments. Analysis of the soil, for total Cu content with depth, showed very little Cu accumulation at any depth in the soil column, beyond the soil surface. In most cases Cu levels remained near the background levels found in the control columns.Moderate correlation was found (r2 = .59 for crude oil; r2 = - .54 for crankcase oil; r2 = .85 for citric acid) between Cu levels and TOC levels in the soil columns with depth.From the results of the current study it can be inferred that practices such as petroleum landfarming and land disposal of some hazardous materials may allow for the migration of both the applied petroleum wastes and any metals which may be contained within.Department of Natural Resources

Full textAbstract:
Water samples and macroinvertebrates were collected from three stations of Finley Creek, Indiana before and after a surface cleanup of an adjacent hazardous waste disposal site. Water quality parameters: iron, total dissolved solids, conductance, hardness, total suspended solids and pH were compared between stations and years. The water quality above the landfill was high but decreased downstream. The water below the disposal site contained high levels of chemicals in both studies. However, the concentrations of chemicals were lower in the water two years after the cleanup.Numbers of macroinvertebrates and the number of taxa were determined and species diversity indicies were established. The results showed a statistically significant increase in macroinvertebrate taxa and mean species diversity indicies below the waste disposal site after the cleanup. These results indicate an improvement of water quality.Department of Natural Resources

Sri Lanka faced many catastrophes in managing wastes because of human errors and climate change impacts. Consequently, government administrators with stakeholder participation drafted a comprehensive policy on all aspects of waste management and now requires planning processes in the national, provincial, and local authority levels. Evidenced-Based Interactive Database is under construction. It will be a platform for all actors to participate in managing all types of wastes, inclusive of quantity and quality of wastes. This chapter describes municipal solid waste management, including present status of technology applications with the emphasis on 3R to divert wastes from landfills. It contains reports on e-wastes collection programs and some processing, polythene recycling, hazardous wastes management, including healthcare wastes, disaster and construction and demolition wastes, informal sector and recyclers, economics of waste management, and case studies. Future directives are given with coupling of intended nationally determined contributions for sustainable waste management.

Thermal plasma torches convert electricity to high-temperature thermal energy by applying a high voltage across a flowing gas stream. Plasma torches are used extensively for producing metallic and ceramic coatings and also for vitrifying hazardous materials, such as asbestos-contaminated wastes. In the last decade, several thermal plasma processes have been proposed for treating municipal solid wastes (MSW). This research is based on a critical analysis of previous work by the Earth Engineering Center and on published reports and examines the possibilities for the proposed thermal plasma (TP) processes to be recover energy from MSW as an alternative to the conventional waste-to-energy (WTE) by grate combustion. In particular, this study will investigate two prominent thermal plasma technologies that are presently under development: The Alter NRG “Westinghouse” process in the U.S. and the Europlasma process in France. The environmental impacts and the technical economic aspects of plasma-assisted WTE processes will be compared to the traditional process of MSW combustion on a moving grate.

Full textAbstract:
The meaningful United States regulation of onshore oil and gas field waste/soil commenced in the mid 1980’s in response to a series of state, federal, industry and international initiatives. Most initiatives centered on the design, construction and operation of earthen pits used in the exploration and production of oil and gas (E&P). Prior to this time, earthen pits were constructed as needed by the operator and used in all phases of E&P activity. Chief concerns of the regulators were focused on what had gone into pits historically, what was going into them currently and was the E&P exemption excluding high volume E&P wastes from the Resource Conservation and Recovery Act (RCRA) regulations justified. Several investigations, including the comprehensive field study by the Environmental Protection Agency in 1987, determined E&P wastes are ostensibly non-hazardous. EPA concluded regulation of E&P wastes under RCRA Subtitle C was not necessary. To this day there is no U. S. federal regulatory program with exclusive jurisdiction over exempt E&P wastes. Other studies, primarily industry and academic, focusing on land limiting constituents, management practices and pit closure strategies revealed sodium salts and petroleum hydrocarbon in the form of diesel range organics were the primary limiting constituents. One state, Louisiana, adopted the technical aspects of these studies and developed a comprehensive regulation known as Statewide Order 29-B, which was based on the concept of limiting constituents and defined post closure performance standards. These standards limited salinity, sodicity, total metals and total petroleum hydrocarbon (oil & grease) with values varying with respect to landform, land use and closure technique. Other states have adopted some of the concepts and criteria advanced under 29-B but none are as comprehensive. Obviously there is a need to control what goes into pits and how pits should be closed. The industry would best be served by adopting the concepts and standards set forth in the Louisiana 29-B regulation. A few of the provisions could be changed to make it more palatable to industry without sacrificing the protection afforded human and animal health, safety and the environment. Internationally, particularly countries in South America embraced USEPA protocol for testing characteristically hazardous wastes, but 1) without the framework to handle the relatively large volume of non-hazardous E&P waste generated and 2) no regulations or protocols for on-site waste management. Several operators, although partners with state owned oil companies, on their own volition, applied the concepts and standards under Louisiana’s 29-B to rainforests in South America and rice paddies in Indonesia. Canada and European oil and gas producing countries have developed stringent standards not based on science, which favor costly treatment technologies. Generally, these countries prohibit cost effective on-site waste management and closure techniques. This paper traces the evolution of waste/soil remediation within the United States and internationally. We trace the progress as a function of time; the impetus for regulation; and probable future controls.
