Item Carbon footprint of public space furniture - Case picco / Kari(2011) Junnikkala, Hilppa; Linkosalmi, Lauri; Peitsalo, Anne-Maria; Puunjalostustekniikan laitos; Kemian tekniikan korkeakoulu; School of Chemical Engineering; Kairi, MattiCarbon footprint was calculated for two Martela Oyj's public space chairs and the results were compared with each other. Chair models that were selected for this study are Picco 316 and Kari 3. Picco chair consist of form pressed seat, which has an upholstery and steel base. Two different surface coatings were selected for Picco chair base: powder coating and chroming. Kari chair consist of form pressed seat and base. There is not upholstery in Kari chair. Carbon footprint of the chairs was determined according to life cycle assessment. Global warming potential (GWP 100) was chosen for the environmental impact category. The objective of the study was also to determine those processes and materials, which produce most of the carbon footprint during chair's bounded life cycle. Data collection for the life cycle inventory analyse phase was conducted at P.O. Korhonen factory and at the Metalli Piiroinen factory. Data collection was also made from different databases. All of the calculations that were acquired by life cycle assessment were done by GaBi 4 software, which is based on ISO 14044 standard. Picco chair with powder coated base had a carbon footprint of 32,83 kg and with chromed base 25,18 kg CO2 -equivalent. Kari chair's carbon footprint was 6,31 kg CO2 -equivalent. The carbon footprint of the Kari chair was remarkably lower than Picco chairs, 80 - 75 per cent. There was also difference between Picco chairs. Chrome base Picco's carbon footprint was 23 per cent lower than Picco with powder coating. Differences between the total carbon footprints of the studied chairs, is mainly due to differences between materials used. The carbon footprints of the chairs consist of three factors; materials, manufacturing processes and logistics. From these factors materials had the most impact on the total carbon footprint, 66 - 86 per cent. Manufacturing processes had the influence of 12 - 32 per cent and logistics affected only by 2 - 5 per cent. The highest emission among materials had the textile of the Picco chair, steel and wooden parts of both chairs. From the manufacturing processes surface treatments of the bases and the form pressed seats as well as processing of the Picco's steel base made the largest contributions to the total carbon footprints.Item Laatujärjestelmän kehittäminen ikkunatehtaalle(1992) Peitsalo, Anne-Maria; Prosessi- ja materiaalitekniikan osasto; Teknillinen korkeakoulu; Helsinki University of Technology; Sipi, Marketta
