This study was carried out to investigate the distribution characteristics of persistent organic pollutants in incineration residues at industrial waste incinerators and municipal solid waste incinerators, which were analyzed by the official analytical method for the endocrine disrupting chemicals and the waste. Seven of 12 persistent organic pollutants were quantitatively analyzed by GC-MSD (SIM-mode). Hexachlorobenzene was detected in 21 samples among 44 incineration residues. The level of hexachlorobenzene was 0.132-8.138 ng/g in incineration residues, 0.195-5.765 ng/g in fly ash at industrial waste incinerators, 0.270-1.828 ng/g in bottom ash and 0.154-50.643 ng/g in fly ash at municipal solid waste incinerators, respectively.

The purpose of this study is to examine the effect of stabilization disposal and recycling on incinerated paper mill sludge ash as cement additives. It was investigated chemical(pH, ICP, TGA XRD) and physical(PDA, SEM) characteristics of the incineration ash. And the pozzolanic characteristics of incineration ash was applied to cement as additive to increase the compressive strength. The results were that the pH characteristic of incineration ash was strong alkalinity, the content of silica and alumina as a pozzolanic material was 50.97%, and the average particle size was $5.03{\mu}m$ respectively. When the ash contents as cement additive were varied in 0~15%(wt) of cement weight to explore the effect of the compressive strength on the solidified cement mortar, the proper amount of the incineration ash substituted was about 5~l0%(wt). Therefore we found that using the incineration ash as cement additive obtains the recycling of waste material, the stabilization disposal, the reduction of waste disposal expense, and the protection of environmental problem, too.

The encironmental consequences of airborne mercury (Hg) release from waste incineration system are wellperceived. To provide some insights into those phenomena, we have assessed annual emission rates of Hg for several major incineration systems in Korea following the procedures developed abroad. The results of our computation, derived on the basis of dividing the whole amounts of annually incinerated wastes into municipal solid Wastes (MSW), and medical solid wastes (MDW), indicate that the extent of Hg release may be significant nationwide, possibly approaching a few tonnes of Hg per year basis. Knowing that the airborne transport and the resulting deposition of Hg can exert serious pollutions to the aquatic ecosystems, of particular fisheries, we are obliged to establish a stringent measure to confine the amount of Hg released via incineration.

Animal waste is a major agricultural waste or wastewater that requires appropriate treatment to prevent environmental pollution. In this presentation, it is examined if incineration of manure compost is an alternative to treatment of animal waste. Heating values of selected biomass including manure compost were obtained using a bomb calorimeter. Based on heating values of manure and manure compost, ranging from 1200 - 1500 kcal/kg on wet base, incineration could be an alternative for animal waste treatment if available land is limited for land application and sufficient reduction of water content in manure compost.

An equilibrium analysis was carried out to determine principal species of heavy metals in waste incineration and their behaviors with variation of temperature, chlorine concentration, excess air ratio, and C/H ratio. The waste was assumed as a compound of hydrocarbon fuel, chlorine, and metals. Calculated results showed that the most important parameter to determine the principal species was temperature. Chlorine concentration also affected on mole fractions of the principal species. Generally principal species at high temperature were chlorides while there were some metals of which principal species were oxides. At low temperature mole fractions of the principal species increased, but at high temperature mole fractions of some metal species decreased. C/H ratio of the hydrocarbon fuel and excess air ratio had little effect on mole fractions of the metal species, compared to the temperature and chlorine concentration.

Due to separate discharge of food waste, large incinerating facilities for municipal waste show the phase change that combustible contents have been increasing while the concentrations of water have been decreasing when wastes are brought in. This phase change of wastes leads to the increase of exothermic value when wastes are carried in, which causes the problems to make the durability of incinerating facilities weak and lower the capacities of them. In accordance with these problems, this study was carried out to present effective plans to operate incinerating facilities as the quantities of municipal wastes of Incheon have been gradually increasing. We examined the problems caused by the phase change of municipal waste in Incheon and managing plans to control the amounts of heat output when intermixed incineration of food waste is conducted. It is concluded that we could carry out the optimized operation of incinerating facilities as well as produce economic effect to reduce processing costs when we conduct the intermixed incineration of food waste and municipal waste, in the trend that the amounts of heat output generated by wastes are gradually increasing. This is because this operation of intermixing incineration contributes to reducing the amount of exothermic heat.

Waste paint, one of the specified wastes in Korea, is currently treated entirely by incineration treatment method, and is hardly recycled compared to other wastes. Incineration treatment method also causes environmental problems such as air pollution. Thus, this study breaks away from the existing incineration treatment method of waste paint and switch to a method of pretreatment operation through evaporation, condensation, and thermal decomposition by temperature control. and then proposes a sustainable waste paint treatment process that can be recycled as an alternative energy heat source. If a new method of disposing of waste paint and technology for recycling are developed and disseminated, it is expected that the effect will be large from an economic and environmental point of view.

This study analyzed concentrations of volatile organic compounds (VOCs) produced from incineration of plastic wastes at $600^{\circ}C$. The plastic wastes used in this study included polyethyleneterephthlate (PETE), high density polyethylene (HOPE), polyvinyl chloride (PVC), low density polyethylene (LOPE), polypropylene (PP), polystyrene (PS) and other. Plastic wastes were heated from room temperature upto $600^{\circ}C$ providing the compressed air inside of a small-scale electric furnace for 90 minutes and then they were oxidized (incinerated) for 60 minutes at $600^{\circ}C$ maintaining the same air supply. VOCs emitted from the incineration process were sampled using an air sampling pump and Tedlar air bags for 150 minutes and then the components and concentrations of the VOCs were analyzed by a GC-MS. The most prominent chemical structure of the VOCs obtained from the incineration process of the HOPE, LOPE and PP, which include ethylene groups in their main chains, was identified as aliphatic hydrocarbons such as 1-hexene. However, aromatics such as benzene were major chemical structure from the incineration of PETE, PVC and PS which include benzene rings in their main chains. This study estimated the total VOC production from the incineration of the plastic wastes based on the real plastic waste production and the emission factors. 64% and 27% of the total VOC emissions consisted of aliphatic hydrocarbons and aromatics, respectively, which have double bonds within their molecular structure and thus a high ground level ozone formation potential.
