The second chapter, on the basis of the Vilnius City Municipality Administration material issue in the processing of secondary raw material situation in the city of Vilnius, municipal waste management systems in the context of an overview of the city of Vilnius secondary materials system. Analyzing the collection of secondary raw materials and processing situation in Lithuania and Vilnius, evaluates the recycled material clean-up costs. The third chapter, on the basis of the survey results and interviews with municipal waste-management companies and experts in data analysis of secondary raw materials handling system, the system management and efficiency. The analysis showed that the city of Vilnius secondary raw materials handling system is not sufficiently effective. The main chains, which organizes its own territory due to municipal waste and secondary raw materials processing is the municipality. Municipality responsible for the waste management system development and management - regulation, development and... [to full text]

This master´s thesis focuses on prediction of presence of reusable material components in municipal waste with special focus on packaging materials. This prediction is based on analysis of financial costs of individual products according to the so-called market basket. Research of packaging´s life cycle and involving legislature is also a part of this thesis.

<p>U okviru disertacije, kori&scaron;ćenjem ve&scaron;tačkih neuronskih mreža razvijeni su modeli za predviđanje količina ambalažnog i biorazgradivog komunalnog otpada u Republici Srbiji do kraja 2030. godine. Razvoj modela baziran je na zavisnosti između ukupne potro&scaron;nje domaćinstva i generisane količine dva posmatrana toka otpada. Pored toga, na bazi zavisnosti sa bruto domaćim proizvodom (BDP), definisan je i model za projekciju zastupljenosti osnovnih opcija tretmana komunalnog otpada u Republici Srbiji za isti period. Na osnovu dobijenih rezultata, stvorene su polazne osnove za procenu potencijala za reciklažu ambalažnog otpada, kao i za procenu u kojoj meri se može očekivati da određene količine biorazgradivog otpada u narednom periodu ne budu odložene na deponije, &scaron;to je u skladu sa savremenim principima upravljanja otpadom i postojećim zahtevima EU u ovoj oblasti.</p> / <p>By using artificial neural networks, models for prediction of the quantity of<br />packaging and biodegradable municipal waste in the Republic of Serbia by<br />the end of 2030, were developed. Models were based on dependence<br />between total household consumption and generated quantities of two<br />observed waste streams. In addition, based on dependence with the Gross<br />Domestic Product (GDP), a model for the projection of share of different<br />municipal solid waste treatment options in the Republic of Serbia for the same<br />period, was created. Obtained results represent a starting point for assessing<br />the potential for recycling of packaging waste, and determination of<br />biodegradable municipal waste quantities which expected that in the future<br />period will not be disposed at landfills, in accordance with modern principles<br />of waste management and existing EU requirements in this area.</p>

Purpose The purpose of this thesis is to set up a closed-loop supply chain model for B2C online subscription box retailers and to develop a business case evaluating the model’s sustainability. Method This explorative thesis has an abductive research approach. Multiple-case studies are conducted and data from four cases and an expert are collected by conducting interviews. The research contains both qualitative and quantitative data. Findings A closed-loop SC model is created with regards to transport packaging. The model suggests that once the package is received by the consumer it can be returned in an empty state. After being cleaned it should be reused by the 3PL. The model’s sustainability is evaluated by developing a business case. Sustainable performance measures with regards to economic, social and environmental practice are assembled. The model enhances general social performance and environmental performance. Economic performance is mostly positively influenced. Options for cost savings in order to improve the economic performance of the model are suggested by the researchers. Practical implications The work provides businesses within the online B2C subscription box retail with a model for a possible closed-loop supply chain with regards to transport packaging. The business case for sustainability can be applied as a guideline to evaluate the model or similar ones. Researchers give suggestions on adapting packaging to enhance economic performance. Societal implications This thesis points out possible environmental and social benefits that may be achieved by a closedloop supply chain model. Besides waste and emission reduction, social performance such as employee motivation is positively influenced. Theoretical implications The thesis provides a model developed from theory and empirical data. The model does not only have practical implementations but also complements theory where a gap has earlier been identified. Through the business case for sustainability researchers contribute to theory since literature is scarce.

Notre recherche porte sur l’influence du cadre institutionnel sur les comportements des organisations. D'une manière particulière, elle s'intéresse à la manière dont les acteurs s'adaptent au cadre institutionnel du champ organisationnel dans lequel ils opèrent. Ces acteurs peuvent même être amenés à tenter de modifier ce cadre pour qu'il corresponde à leurs intérêts. La RSE est appréhendée dans notre réflexion comme un phénomène institutionnel, susceptible d'être mis en œuvre par le biais des pressions normatives, coercitives et mimétiques. Le champ d’observation de cette recherche porte sur les déchets d’emballages ménagers et les véhicules hors d’usage. Les résultats obtenus indiquent que le type de déchet, la taille des producteurs, le degré d’institutionnalisation et les caractéristiques du champ organisationnel influencent fortement l’action des institutions et des organisations encastrées dans le champ étudié. Les résultats se traduisent par les apports théoriques suivants : contribution aux études sur la formation des champs organisationnels ; contribution à l’étude du changement institutionnel à travers la confrontation institutionnelle ; contribution au courant théorique qui définit la RSE comme stratégie de business case ; mise en lumière du principe REP comme extension particulière de la RSE. / Our research concerns the influence of the institutional framework on the behavior of organizations. In a particular way, she is interested in the way the actors adapt themselves to the institutional framework of the organizational field in which they operate. These actors can be even brought to try to modify this framework so that he corresponds to their interests. The RSE is arrested in our reflection as an institutional phenomenon, susceptible to be implemented by means of the normative, coercive and mimetic pressures. The field of observation of this research concerns the waste of domestic packagings and end-of-life vehicles. The obtained results indicate that the type of waste, the size of the producers, the degree of institutionalization and the characteristics of the organizational field strongly influence the action of the institutions and organizations embedded in the studied field. The results are reflected in the following theoretical contributions: contribution to studies on the formation of organizational fields; contribution to the study of institutional change through institutional confrontation; contribution to the theoretical current that defines CSR as a business case strategy; the REP principle as a particular extension of CSR.
