Background: Accurate and realistic data regarding hazardous waste generation is required to make improvements in the effective management of hazardous wastes. Battery and accumulator manufacturing industry is one of the priority industries which was investigated in this study under the project named “Hazardous Waste Management in Compliance with European Union Environmental Regulations in Turkey”. The project investigated a number of different industries for the development of an internet-based system named as “The Hazardous Waste Declaration System” in order to meet the requirements of Turkey for hazardous waste management. Objective: In this paper, hazardous waste generation factors were asserted by means of the type and quantity of the hazardous waste originated from the battery and accumulator manufacturing sectors. Method: For this purpose, field studies were conducted in an industrial plant operating in the sector, in order to determine all inputs and outputs of the current manufacturing process utilized. Concurrently, hazardous waste generation declarations made by the industries in the years 2009 and 2010 to the Hazardous Waste Declaration System were evaluated and a range of hazardous waste generation factors were created using the possible minimum and maximum quantities for each waste and the results were compared with the data given in the literature. Results: This paper presents the waste lists and the hazardous waste generation factors for the battery and accumulator manufacturing sectors. Conclusion: It is believed that the study will provide invaluable information for other battery and accumulator manufacturing industries from the point of types and quantities and the management of hazardous wastes generated.

In this article, the estimated amount of hazardous waste generation factors (HWGFs) was investigated by the types and quantities of hazardous wastes originating from the plastic product production sector using the data obtained from the field studies. The amount of hazardous waste in the similar plastic product production industry in Turkey were estimated by using HWGFs calculated in this works the production along with capacity information belonging to the sector. The best available techniques (BAT) were proposed to the industry to reduce hazardous waste It is believed that this article will provide benefit regarding the reduction and the management of hazardous wastes generated by similar plastic product manufacturing industries in the world. Plastic product manufacturing industry is also the one of the priority industries that investigated in the project titled "Hazardous Waste Management in Compliance with European Union Environmental Regulations in Turkey" by the support of TUBITAK (The Scientific and Technological Research Council of Turkey). Current production processes were investigated to cover all inputs and outputs and hazardous waste lists and hazardous waste generation quantities per unit manufacturing (hazardous waste generation factors, HWGFs) were calculated for the mentioned industry. At the same time, hazardous waste generation quantity declarations made by industries in 2009 and 2010 to an internet based system called "Hazardous Waste Declaration System (HWDS)were evaluated and the range of HWGFs were created using possible minimum and maximum quantities for each waste using in this study and the literature data.
