Background & Aims of the Study: Increasing hazardous INDUSTRIAL WASTES and lack of necessary regulations for management of them have led to serious problems in some parts of Iran. The aim of this study was to evaluate the situation of collection, transportation, recycling, and disposal of hazardous INDUSTRIAL WASTES in the Khazra INDUSTRIAL Park of Kerman, Iran.Materials & Methods: This study was a descriptive cross-sectional study that was done using questionnaires and local visits during year 2009. In this questionnaire, some information about the INDUSTRIAL WASTES, production, storage on site, collection, transformation, sorting, recycling, and disposal were recorded.Results: In the Khazra INDUSTRIAL Park, 71, 600 kg/day of different INDUSTRIAL waste is produced. The biggest proportion of waste includes metals, and construction and demolition waste which are about 16, 500 tons a year. The smallest proportion is non-iron metal waste, which is produced at a rate of 8 tons per year.88.7 percent of the active industries at the Khazra INDUSTRIAL Park produce solid INDUSTRIAL waste. Most of the INDUSTRIAL units do not use a united and coordinated system for storing waste and have no specific place for temporary storage inside the INDUSTRIAL park. The majority of INDUSTRIAL waste collection, which is about 59.8%, is done by private contractors. The INDUSTRIAL units transfer their waste separately, and just 9 INDUSTRIAL units recycle their waste. Disposal of these WASTES is mainly done by selling to trading agencies. Each day, 3 tons of hazardous INDUSTRIAL waste is produced in this park. The highest production belongs to the oil factory (Keyhan Motor).Conclusions: According to the results, the Khazra INDUSTRIAL Park needs a unified system for storing, transporting and collecting the sorted waste, and it also needs to have a transportation station with basic facilities. The WASTES of most INDUSTRIAL units at the Khazra INDUSTRIAL Park have the potential for recycling and re-usage in other industries. The best, most economic, and most environment-friendly waste management activity of the Khazra INDUSTRIAL Park is prevention of production, increase in the potential of recycling, and reuse of material with emphasis on sorting at the production site, increase of mechanical sorting, and decrease in production of disposable waste.

Background: Production of solid waste is the result of the human’s different activities that today has changed a lot in comparison to the past due to the changing life styles and pervasive expansion. In Isfahan province lots of WASTES are produced daily. Due to the importance of the waste and its recycling, the purpose is determining the production scopes of different WASTES in order to find a proper place for recycling.Methods: In order to analyze the zoning of INDUSTRIAL and urban waste, the waste production status in different groups were studied and evaluated in this province. According to the type of industry the WASTES can be divided into ten groups of metal, glass, construction and masonry WASTES, rubber and plastic, paper and card board, electronic waste, decayed automobile, textile, wood and so on.Findings: In this article the composed map of produced waste in different groups in the INDUSTRIAL towns, dispersed industries and the provinces were drown by Arc GIS software, so based on the WASTES distributions, a proper recovering place WASTES are considered by the related industries.Conclusion: The distribution of recyclables are shown on the maps prepared include organic metal material (i.e. glass), cellulosic material (wood), chemical (rubber and plastic) and textiles, electronic and electric WASTES and decayed automobile; in order that according to their accumulation, the proper places to recycle different WASTES are recognized.

In this study, environmental impacts of INDUSTRIAL waste disposal used lubricating oils and sulphur WASTES scenarios have been investigated and modeled. The life cycle assessment methodology was selected among the environmental impact assessment methods. In this method environmental issues and burdens were quantitated in order to facilitate the comparison. In this regard, options with the least adverse impacts were suggested. Functional unit of the study has also been defined as amount of used lubricating oils and sulphur WASTES in terms of kilogram base on capacity of transitional barrel. Accordingly the system boundaries were selected for life cycle of the WASTES produced in sulphur unit of Tehran Oil Refinery. Since the main disposal method applied in Tehran Oil Refinery was transference to the municipal landfill, two incineration and landfilling scenarios were modeled for used lubricating oils and sulphur WASTES by means of Simapro-7.1 software. Then, the outputs of these scenarios were compared in terms of the least environmental impacts by EDIP 2003 and Ecoindicator 99 methods. Finally, incineration scenarios were recommended as the most efficient ones.

he present research tries to study the different solid waste materials of the industries in Tehran. Among 918 INDUSTRIAL units of Tehran province who had morc thon 50 staff, 389 units were chosen. From these units 54 were selected with attention to production line, existing solid. WASTES, cooperation of health professionals and questionnaires. In this units the recycling methods, collection procedures, transportation and finally, the ultimate removal of the INDUSTRIAL waste materials have been analysed. Out of the 54 INDUSTRIAL units which were examined, 25.9 percent were governmental industries, 31.5 percent were under the semi-public management and 42.6 percent were the private factories. Industries were divided to seven categories based on ministry of industries classification, then selection rate of each group was mentioned as follows: 11.1 percem were the food industries, 16.7% chemical or drugs industries, 11.1% the electricalor electronic indu.stries and 7.4% wood or paper industries. The leather and textile industries covered 13 percent of the samples. The highest percentage belonged the metal industries with 24.1 percent rate followed by, the nin-ferrous mineral industries possessed 16.7 percem in this row. From the seven INDUSTRIAL groups mentioned above. the highest and lowest rate were obtaind from the metal industries and the wood and paper industries respectively.In 90 percent of the selected cases, certain personnels in charge of the collection of the INDUSTRIAL waste products, weresafety clothes. The last findings relate to the final removal of the waste products. In 55 percent of cases, this is done by the municipality and in 27.7 percent of cases, the private sector undertakes the job for the factories. In 16.8 percent remaining cases, the factories themselves take actions for the removal of their INDUSTRIAL waste materials

Purpose Agro-INDUSTRIAL WASTES are posing serious challenges for the agro-industries. Composting and co-composting of such WASTES will lead to converting such WASTES into a useful product that will serve as a soil conditioner. The present research investigated the kinetics of composting and co-composting of several agro-INDUSTRIAL WASTES.Methods Seven pilot scale composting and co-composting piles of substrates from grain dust (GD), coffee-processing waste (CPW) and olive mill waste (OMW) were tested. Temperature and moisture content of the piles were monitored during the composting process and adjusted whenever necessary.Results The biodegradation kinetics was found to be of first order for all composting and co-composting piles. As judged by the value of the reaction rate constant, and the temperature of the piles, the biodegradability of the grain dust was the highest among all composting piles, followed by the coffee-processing residue and finally the fresh olive mill waste. As for the co-composting, the highest degradability was noticed in the pile that was composed of grain dust and coffee-processing waste followed by that of grain dust mixed with dry olive mill waste, and then followed by coffee-processing waste and dry olive mill waste and finally by grain dust with fresh olive-processing waste.Conclusions Composting and co-composting of agro-INDUSTRIAL WASTES is a low cost and an environmentally friendly waste management option for solving the problem of the disposal of such waste. The study revealed that all piles followed first-order kinetics with different biodegradability rates.
