The relation between education, knowledge and action for better waste management in Poland.

In recent years a significant increase in municipal solid waste (MSW) amount has been noted in Poland, and yet there is no fully efficient system for its treatment. Undertaking projects for rational MSW management requires considering both technical facilities and social barriers (waste reduction, re-use and segregation in households). In Poland, attempts to educate and mobilise society to segregate recyclables have not yet produced satisfactory results. Society's awareness in this field needs to be raised. The purpose of this study was to determine the level of knowledge and understanding about MSW management and the relationship between knowledge possessed and actions undertaken for various residential age groups in two Polish provinces. In all groups, 30% of the respondents showed a satisfactory level of knowledge, whilst an equally small number of individuals had undertaken actions for MSW management at home; people with a higher level of knowledge undertook such actions slightly more often. No significant differences between the provinces were found, but residents of town, where waste segregation has been introduced simultaneously with an information campaign, showed a higher level of knowledge. The study points to the need to further educate people about MSW, and to encourage the teaching of pro-environmental attitudes.

Assessment of medical wastes management practice: a case study of the northern part of Jordan.

This study includes a survey of the procedures available, techniques, and methods of handling and disposing of medical waste at medium (between 100 and 200 beds) to large (over 200 beds) size healthcare facilities located in Irbid city (a major city in the northern part of Jordan). A total of 14 healthcare facilities, including four hospitals and 10 clinical laboratories, serving a total population of about 1.5 million, were surveyed during the course of this research. This study took into consideration both the quantity and quality of the generated wastes to determine generation rates and physical properties. Results of the survey showed that healthcare facilities in Irbid city have less appropriate practices when it comes to the handling, storage, and disposal of wastes generated in comparison to the developed world. There are no defined methods for handling and disposal of these wastes, starting from the personnel responsible for collection through those who transport the wastes to the disposal site. Moreover, there are no specific regulations or guidelines for segregation or classification of these wastes. This means that wastes are mixed, for example, wastes coming from the kitchen with those generated by different departments. Also, more importantly, none of the sites surveyed could provide estimated quantities of waste generated by each department, based upon the known variables within the departments. Average generation rates of total medical wastes in the hospitals were estimated to be 6.10 kg/patient/day (3.49 kg/bed/day), 5.62 kg/patient/day (3.14 kg/bed/day), and 4.02 kg/patient/day (1.88 kg/bed/day) for public, maternity, and private hospitals, respectively. For medical laboratories, rates were found to be in the range of 0.053-0.065 kg/test-day for governmental laboratories, and 0.034-0.102 kg/test-day for private laboratories. Although, based on the type of waste, domestic or general waste makes up a large proportion of the waste volume, so that if such waste is not mixed with patient derived waste, it can be easily handled. However, based on infections, it is important for healthcare staff to take precautions in handling sharps and pathological wastes, which comprises only about 26% of the total infectious wastes. Statistical analysis was conducted to develop mathematical models to aid in the prediction of waste quantities generated by the hospitals studied, or similar sites in the city that are not included in this study. In these models, the number of patients, number of beds, and hospital type were determined to be significant factors on waste generation. Such models provide decision makers with tools to better manage their medical waste, given the dynamic conditions of their healthcare facilities.

Waste management for Space Station Freedom.

Because of the tremendous task of designing, testing, building and maintaining the waste systems for Space Station Freedom, different methods of managing these systems are now being developed. This paper summarizes some of those methods. The first task for the design engineer is to develop systems and hardware to handle waste in the special conditions of the space station. Different closed and open loop systems, along with the development of new hardware in these loops, are being tested to meet this task. Some of the new hardware to be discussed are water and air monitors, hazardous material handling, and plumbing hardware such as commodes, showers and clothes washers. The second task is to develop methods to manage the process of developing these systems. Some of the areas to manage are testing information, materials, facilities, people, budgets, time, safety, legal responsibilities and testing standards. The last task is to incorporate the new technologies for other areas besides space stations. Other areas would include long-duration space missions, lunar stations and other non-space applications.

Infectious medical waste management. A home care responsibility.

With the proliferation of bloodborne diseases in the United States, more attention is being focused on the issues of infectious medical waste and its disposal. Home care organizations must be aware of the potential risks involved in handling infectious wastes, and adhere to industry standards of disposal and transport. Education of staff, patients, and community about the management of infectious waste is crucial in today's healthcare arena.

Ion exchangers in radioactive waste management: natural Iranian zeolites.

Five samples of natural zeolites from different parts of Iran were chosen for this study. In order to characterize and determine their structures, X-ray diffraction and infrared spectrometry were carried out for each sample. The selective absorption properties of each zeolite were found by calculating the distribution coefficient (K(d)) of various simulated wastes which were prepared by spiking the radionuclides with (131)I, (99)Mo, (153)Sm, (140)La and (147)Nd. All the zeolite samples used in this study had extremely high absorption value towards (140)La; clinoptolite from Mianeh and analsite from Ghalehkhargoshi showed good absorption for (147)Nd; clinoptolite from Semnan and clinoptolite from Firozkoh showed high absorption for (153)Sm; mesolite from Arababad Tabas showed good absorption for (99)Mo; and finally mesolite from Arababad Tabas, clinoptolite from Semnan and clinoptolite from Firozkoh could be used to selectively absorb (131)I from the stimulated waste which was prepared. The natural zeolites chosen for these studies show a similar pattern to those synthetic ion exchangers in the literature and in some cases an extremely high selectivity towards certain radioactive elements. Hence the binary separation of radioactive elements could easily be carried out. Furthermore, these zeolites, which are naturally occurring ion exchangers, are viable economically and extremely useful alternatives in this industry.

Report: transboundary hazardous waste management. part II: performance auditing of treatment facilities in importing countries.

Before implementing the self-monitoring model programme of the Basel Convention in the Asia, Taiwan has conducted a comprehensive 4-year follow-up project to visit the governmental authorities and waste-disposal facilities in the countries that import waste from Taiwan. A total of nine treatment facilities, six of which are reported in this paper, and the five countries where the plants are located were visited in 2001-2002. France, Belgium and Finland primarily handled polychlorinated biphenyl capacitors, steel mill dust and metal waste. The United States accepted metal sludge, mainly electroplating sludge, from Taiwan. Waste printed circuit boards, waste wires and cables, and a mixture of waste metals and electronics were the major items exported to China. Relatively speaking, most treatment plants for hazardous waste paid close attention to environmental management, such as pollution control and monitoring, site zoning, system management regarding occupational safety and hygiene, data management, permits application, and image promotion. Under the tight restrictions formulated by the central environment agency, waste treatment plants in China managed the environmental issues seriously. For example, one of the treatment plants had ISO 14001 certification. It is believed that with continuous implementation of regulations, more improvement is foreseeable. Meanwhile, Taiwan and China should also continuously enhance their collaboration regarding the transboundary management of hazardous waste.
