2. LEARNING OUTCOMES
The course is teaching a hazardous waste has the potential to cause an unacceptable risk to public health and the environment. The hazardous waste should be defined by international organizations like United Nations Environmental Programme (UNEP), US EPA (Environmental Protection Agency), European Waste Catalogue, etc.
The students would learn about hazardous waste lists, origin, forms, characteristics, and properties. Also, the kind of wastes that excluded from hazardous waste like:
The students will be informed about the Basel Convention.
Risk assessment is the process to evaluate the potential for adverse health or environmental effects from exposure to naturally occurring or synthetic agents (compounds). Risk assessment typically includes an estimation of the probability of harm or the effect that a chemical in the environment may have on wildlife. Risk assessment involves four components: hazard identification, dose-response assessment, exposure assessment, and risk characterization.
The students will learn about hazardous waste compatibility that is the ability of two or more materials to exist in close association with each other without the formation of harmful chemical or physical reaction. There are many undesirable reactions by mixing incompatible wastes.
The student will be informed about thermal treatment of hazardous waste that is the destruction of hazardous waste by thermal decomposition. Thermal treatment methods include:
The solid residues are consisted of bottom ash or slag, fly ash and air pollution control (APC) residues. Terms and regulations on treatment and disposal of solid residues differ between countries. Bottom ash may be landfilled or used as an aggregate substitute e.g. for road construction.
The students will emphasize on the physicochemical treatment of hazardous waste. The physical processes enable different waste components to be separated or isolated, for re-use or appropriate treatment or disposal. The chemical processes use chemical reactions to transform hazardous wastes into less hazardous substances (reduce risk potential). They often used in combination to optimise hazardous waste treatment.
The students will learn about hazardous waste landfilling. It requires secure landfill site dedicated to disposal of hazardous waste. The site must be: highly engineered, should have discrete cells for different waste types, separated by barriers and designed to resist leakage, segregate incompatible wastes, contain waste in a safe manner and prohibit contact between landfill contents and surrounding environment. The student will learn the basic principles of secure hazardous waste landfill and ‘ultimate’ landfill.
Lastly, the students will learn about special hazardous waste like Polychlorinated biphenyls (PCBs) and Dioxins / Furans. PCBs are persistent in the environment, travel very far away – Artic circle, build up in environment and affect human health, contaminate the marine food chain and NO ONE is PCB-free, stored in body fat, very slowly eliminated. The dioxins/furans are chlorinated organic chemicals with similar structures, the chlorine atoms can be attached in 8 different places on the molecule and the harmful effects of dioxin vary according to where the Cl atoms are located.
