The aim of this degree project was to study the use and presence of plastic in municipal large-scale catering establishments from preschool to high school and in geriatric care. It was also to get a deeper knowledge about the substance BPA and the plastic PVC and their connection with food. The third aim was to lay forward some suggestions for Eskilstuna about continued work and substitution in their municipal large-scale kitchens. The means for data gathering was databases, websites, scientific reports, on site visits, interviews, online survey and communication by phone and email. The result from the case study was that plastic articles as containers, disposable materials, utensils and food packages for storing food were used in hot, ambient, cold and freezing temperatures. Nine types of plastic were found: PP, PE, PC, PVC, PA, PS, PET, melanin and SAN. All large-scale kitchens had disposable gloves, plastic films and plastic bags. In the first two examples, some brands were made of PVC-plastic. PC-plastic was found in some drinking glasses, plastic food pans, utensils, bowls and jugs. BPA is a common additive in production of PC-plastic and therefore these articles may contain BPA. Between all ten municipal large-scale kitchens, there are some differences and similarities. Of all the kitchens, no one had exactly the same articles or methods, and some had also special routines that differed from the others. The suggestions to Eskilstuna municipality were to remove those articles that contained BPA or chlorinated plastics (especially those products that already had an alternative on the procurement contract), contact the suppliers and wholesalers and ask which products that both are made of PC and contain BPA or other bisphenols, develop a exchange plan for products that do not fulfil the future regulations of KRAV and finally demand in procurement that the product do not contain BPA, PVC or other chlorinated plastics. / KRAV-certifiering av kommunala storkök inom Eskilstuna kommun
