This study aimed to create a mapping-depended methodology in delineating the suitable territories for Industrial Symbiosis (IS) initiatives. The Geographic Information System (GIS)-integrated Fuzzy AHP (FAHP) was applied to the data of olive pomace (OP), marble processing wastes (MPW) and plastic wastes (PP/PET) generated in the whole country (Turkey). In the proposed methodology, factor identifications and their pairwise comparisons need to be made by experts. Factor weighting was implemented by FAHP method for each waste type. The highest FAHP weights were calculated as 0.57 for OP facility capacity, 0.64 for marble facility capacity and 0.41 for plastics industrial estate factors (high consistency: CR < 0.1). Potential region maps were prepared by integrating these factor weights into GIS. The second-stage FAHP was applied for determining the wastes transportation factor weights to be used in the delineation of intersecting regions. At this stage, OP and MPW have the equal and higher factor weights (0.41) than plastic wastes (0.18). The number of provinces having higher potential for establishing IS facility increased from 10 to 22 province as compared to the case with equal transportation weights. Southern Marmara, Aegean, Mediterranean and Central Anatolia were found as the regions with the higher potential for IS initiatives. The common features of the provinces in these regions are high waste generation capacities and spatially closeness to the provinces having high waste generation capacities. The proposed flexible methodology can be adapted to all types of wastes, to all number of factors (criteria) and to all countries. [ABSTRACT FROM AUTHOR]

Bacterial cellulose has superior physical and chemical properties, biocompatibility, and purity. However, the high production cost obstructs the common use of this polymer. This study investigated the efficiency of olive pomace, an important by-product of olive oil industry in Turkey, as a carbon source for Novacetimonas hansenii. Olive pomace pretreatment with 1% H3PO4 was followed by enzymatic hydrolysis. The maximal reducing sugar concentration upon enzymatic process was 9.3 g/L with 1 enzyme: 6 substrate (dry matter) ratio. After incubation in the growth media prepared with the obtained reducing sugar as carbon source, the highest bacterial cellulose production was 0.68 g/L. Structural analysis indicated that bacterial cellulose from the enzymatic media and the conventional Hestrin-Schramm medium possess similar characteristics. The present work provides a favourable method to reduce the cost of bacterial cellulose production. [ABSTRACT FROM AUTHOR]
