关键词： e-Waste   Management   Methodology   Sustainability   Waste electric and electronic equipment   WEEE MANAGEMENT   CIRCULAR ECONOMY   BENEFITS  

摘要： Waste electric and electronic equipment (WEEE) became an important waste stream due to its recycling potential and negative effects on the social, economic and environmental aspects. Currently, the eval-uation of WEEE management systems focus on specific parts of their lifecycle (mostly on recycling op-tions), providing information on environmental impacts and/or economic benefits. Therefore, a methodology that would address the entire WEEE lifecycle and the 3 pillars of sustainable development (environmental, economic, social) is necessary. The proposed SUSTWEEE methodology dedicated exclusively to the WEEE stream comprises a 4 level methodology, with indicators to be addressed on background information, WEEE generation, WEEE technical performance and sustainability. The tech-nical performance and sustainability aspects are evaluated on 7 main categories of indicators, both quantitative and qualitative, assessed according to 44 criteria. All the indicators went through a score allocation and a normalization step where a percentage, qualitative score and color coding were assigned, resulting in a WEEE evaluation matrix. In the validation step, the methodology was tested successfully at national level to evaluate the sustainability of WEEE management system in Romania in reference year 2014. The results obtained in this case show a rather mixed performance, with indicators in extreme situations. The main hot spots were the very low collection rates and the non-existent reuse rate, at least in official data, while the other indicators indicated at least medium performances. The best performances are in the area of WEEE collected that undergoes suitable treatment, the existence of WEEE facilities in Romania capable to perform the treatment, high recycling rate and the overall environmental performance indicator.

关键词： ROI   Isomorphism   Business network contract   Holon   SPATIAL PROXIMITY   FORMS   FIRM   INSTITUTIONALIZATION   ORGANIZATIONS   COORDINATION   REPUTATION   LEGITIMACY  

摘要： Purpose Paper aim is to analyse and consider the business network contract (BNC) as a model of voluntary holarchy in which the holons are isomorphically linked between them by means managerial chooses and laws to reach a communal and individual survival condition. Design/methodology/approach The Italian SME manufacturing firms signing a BNC are seen as holonic elements in an adaptive system. Data drawn from the Italian business register are analyzed to understand the driving factors of the firms' adaptation and survival, by using descriptive, causality and analysis of variance (ANOVA) statistical techniques. Findings The main findings of the paper support the holonic approach by demonstrating that BNC are alliances based on strategic relations able to create synergies and increase performance. Empirical results suggest that "internal and external efficiency," given by knowledge sharing practices and firms' geographical proximity will positively influence BN firms' productivity, although without resorting to investments (tangible or intangible). Practical implications BNC is an instrument able to introduce common rules and finalized isomorphic behaviors making firms acting as a holon with positive effects on performance. Originality/value This work enriches the existing literature by joining the systemic approach with the network theories and providing evidence of the suitability of the "holon" construct as the basis for a multi-level framework for the study of organizational networking.
