This thesis examines costing systems adopted within Turkish and British paper industries and assesses the appropriateness of Activity Based Costing for this area. It includes two case studies, one of which was performed in a Turkish paper mill and the other in a British one, that describe and examine product costing methods adopted and cost drivers employed within the costing system. The study also contains the results of two questionnaire surveys, one of which was applied to the Turkish and the other to British paper industry. All paper mills in the two industries were included within the survey response rates of which are 65.2% and 40.25% of the Turkish and British mills respectively. The questionnaire survey was designed to shed light into the costing practices adopted within the two paper industries. The results of the case studies and surveys indicated that the existing costing methods adopted and cost drivers employed within the two industries were appropriate for their manufacturing environments. Almost all the mills surveyed were found using traditional methods for their product costing and decision-making needs. Although ABC was implemented by a small number of factories, it was found inappropriate by two mills (one Turkish and one British) and hence abandoned. Different production processes and product types were identified as the main reason of this unsuitability. Also, most non-volume-related activities that may produce cost distortion in electronic and machinery-parts industries either do not exist or the effect of which over products is not important in the paper industry. Machine hour and production tonne cost drivers were found as being employed generally in both paper industries studied.

Abstract Production of pulp and paper from raw wood involves the washing of substantial quantities of highly coloured material from the wood pulp. Although most of this colour is trapped within the mill and the mills wastewater treatment system, discharge of coloured wastewater remains a problem of public concern. Lake Rotorua, New Zealand is filled with sediment consisting almost exclusively of diatoms. The most abundant species, Aulacoseira, has been shown to have very small pores, less than 200 nm, that could be very useful for the capture and holding of large organic molecules. Lake Rotorua is situated close to the two largest pulp and paper mills in New Zealand and may have to be dredged to solve a problem of eutrophication. Wastewaters generated at the Kinleith (Tokoroa) and Tasman (Kawerau) mills in the North island of New Zealand have been used to assess the characteristics of colour removal by Lake Rotorua diatoms. Vacuum filtration through the diatoms succeeded in removing colour but proved to be impractically slow as an industrial process. Addition of diatoms to wastewater streams in stirred experiments showed that significant adsorption took place. The majority of the colour was removed within 30 seconds of mixing. The efficiency of colour removal was found to vary between wastewater streams within the mills. The pH dependency of this removal was tested and found to be most effective in a pH range of 3.6 to 5. Attempts to reuse the diatoms showed that chemical backwash regimes were more effective than calcination. This study concluded that surface silanols were likely to be the principle agent in forming coagulants with the colour material and were subsequently trapped on the diatom surfaces, but more importantly within the pores.
