Dielectric heating technologies (microwave and radio-frequency, RF) bring unique capabilities to the processing of hazardous wastes. Potential opportunities for using these techniques can be described by classifying and matching waste streams to the particular features of dielectric heating. Microwave and RF applications for processing hazardous waste are at various stages of development and include: solvent recovery, regeneration of activated carbon, pyrolysis of rubber tires, soil remediation, and disinfection of hospital wastes. Other solutions to environmental problems can include the replacement of conventional fossil-fired processes (eg, RF-assisted post-baking of biscuits) and microwave heating of catalyst substrate materil for automotive emission control. Examples of dielectric heating systems that are processing hazardous waste are used to illustrate the benefits of these technologies and to characterize future opportunities.

Increasing industrialization and globalization has spawned the unprecedented generation of environmental toxic and hazardous wastes. The existence of publicly known hazardous waste problems such as toxic spills, and river pollution that pose serious and very real threats to human health puts extensive pressure on the government to take an aggressive role in hazardous waste control and transportation. The main objective of hazardous waste transportation is public safety. Each government has the responsibility to ensure that hazardous materials should be transported safely for the social and economic good of the country. Hazardous waste management is now a major and urgent global concern. Various techniques, models, and guidelines for the perception of risks associated with the transport of the hazardous materials are developed. Database of the accident data are developed by transportation agencies to be used for the development of models to improve safety of hazardous waste transportation. Based on the available risk perception models, accident models, the type of hazardous material, origin/destination, and the availability of emergency response routes for their transport are properly designed. Advanced technologies, automated vehicle location system (AVL) and geographical information system (GIS) are also used for the analysis and modeling for the safe transport of hazardous materials. The purpose of this project is to present a literature review of hazardous waste materials and their impact on human health, regulations to control the movement of hazardous materials, Basel Convention and its effectiveness, treatment and disposal of hazardous materials, model developments for risk perception and management and the use of advanced technologies for safe transportation of hazardous wastes. Based on the literature review, the conclusions and future recommendations for possible improvement of the models and techniques used for safe transportation of hazardous wastes are presented.

The Ministry of Environment, South Korea, is involved in efforts to reduce safety-related accidents that could occur during hazardous waste disposal and minimise the environmental impacts of waste disposal. To reach such goals, new factors have been added that contribute to the hazardous characteristics of hazardous waste. The Ministry is also expanding regulations on inorganic and organic components present in hazardous waste for these factors and continues to correct the classification system to establish standards for waste components. Metallic dust, for example, is mostly generated during the operation of melting furnaces or precipitators and dangerous materials contained in this dust may cause accidents, such as explosions or fires. South Korean accident cases have confirmed that waste containing hazardous materials, such as Mg, Al and Mg–Al alloys, can cause such events. Therefore, this study analysed 28 dust samples collected from the dust accumulated in precipitators in 28 metal manufacturing facilities in South Korea. Nine samples were flammable and four samples were reactive to water. Two samples also exhibited leaching toxicities. The results applied to relevant laws in South Korea showed that the proportion of waste containing hazardous characteristics increased from 7.14% in the previous management category to 39.29% in the extended category, an overall increase of 32.15 percentage points.

A general picture of waste management in Argentina is presented, taking into consideration the obligations of the state to guarantee the collection of household waste and to dispose of it in authorized sites and the generator's responsibility on the management of hazardous waste. Separate boxes are presented to present the activities performed by organized waste pickers and by CEAMSE, a state-owned company responsible for waste disposition in the metropolitan area of Buenos Aires. Waste management is essential for a sustainable development agenda. As witnessed in Argentina, this requires (1) closing open dumpsites, (2) a reliable and complete waste collection service, and (3) proper treatment of all waste streams. It is thus clear the need to (1) promote a circular economy; (2) tackle the management of organic waste; (3) ensure the adequate control and treatment of hazardous waste; (4) promote a suitable set of policies, regulations, and economic instruments; (5) select the best available technologies; and (6) formalize the informal phase of recycling.
