    The objectives of this study was to investigate the cause of the local whiteness in AURAÒ blue cheese and to find the way which reduces the white cheeses. It was studied if white cheeses have a compact or open structure. White cheeses were classified as compact and open. Scanning electron microscopy was performed on compact, open and mouldy cheeses. Factors which cause compact cheese were also studied. At the beginning of blue cheese manufacturing, citrate was analysed at different time points in different vats. The aim was to make compact cheese in one of the trials. Cheese curd was broken before and after moulding. Alternative factors including the effect of addition of salt to the vat on reducing the amount of white cheeses was also studied. Other variables were the speed of the drying belt, heating of vat, the amount of vat whey and the different moulds were also studied. In addition it was studied how separation of whey affects to the amount of compact cheeses in the drying belt. Microbiological and chemical analyses as well as density and texture measurement were performed on the trials. Most of the white cheeses were compact and the small amount of white cheeses had an open structure. The compact cheeses had less mould and yeast than the mouldy cheeses. The pH was lower and the amount of free amino acids was less in the compact cheeses than the mouldy cheeses. The compact cheeses were more dense than the mouldy cheeses. Measurements from texture analyser showed that the hardness of compact cheese were greater and the fracturability of compact cheese was lower than the hardness or fracturability of mouldy cheese. There were no differences in the amount of citrates between days or vats. Broken cheese curd before moulding caused a more compact structure. The addition of salt in the vat did not affect the white cheeses. The compact cheeses decreased when the speed of the drying belt was reduced. With the use of the new mould, less compact cheeses were produced than with older mould. The removal of water from cheese curds is logarithmic the longer they are on an open drying belt. The compact cheese also decreased logarithmically when cheese curds were on drying belt from zero to ten seconds. There was a greater amount of compact cheeses after moulding in the vat.

    New environmental product policy measures (RoHS, WEEE and EuP directives), targeted to the products of electrical and electronics industry, are entering into force during 2005-2007. This report raises key questions that companies have confronted in anticipating and interpreting these new requirements in their operations, focusing especially on changes needed in product development and supply chain management. The report reveals that the work needed in companies to comply with the new requirements may begin years before the requirements enter into force, and it may take different forms. Depending on the resources companies possess, this work can vary from influencing the actual contents of the new regulation being developed to adjusting to new requirements and incorporating them into different company operations (product development, manufacturing, sourcing etc.). Two Finnish company cases are reported. The first describes how Vaisala Oyj is implementing RoHS requirements together with its key suppliers. The second case assesses the Commission’s Integrated Product Policy pilot exercise on mobile phones, which was lead by Nokia Oyj during 2005. The report provides companies with useful information about practical experiences of proactive companies in environmental policy implementation, and policy makers with information for the assessment and future steering of environmental product policy in the European Union. This report is the final report of the YPSE research project, which was carried out during 2004-2005. It was financed by the Finnish Environment Cluster Program by the Ministry of the Environment and Technology Industries of Finland. The aim of the project was to assess how companies in the electrical and electronics industry “interpret” and negotiate with each other (and with environmental authorities) the contents of these new requirements, which are still to some extent unclear. It has been of interest what kinds of changes the new requirements create in products and what kinds of operational practices evolve in the industry, for example in the area of material data management.
