A social dilemma perspective on socially responsible consumption

Lee, Ada Lai Yung 29 August 2016 (has links)
Recent research on corporate social responsibility has focused on the corporate level, whereas limited research has been conducted at the individual level most commonly referred to as socially responsible consumption. Recycling is a kind of socially responsible consumer behaviour because it benefits the society as a whole in the long term but involves a personal cost and does not benefit the individual consumer directly. Previous studies on recycling have used theories such as the theory of interpersonal behaviour, means-end chain theory, theory of planned behaviour or norm activation model. However, these theories have only explained part of recycling behaviour and are inadequate because they have not explained it from a social dilemma perspective. A social dilemma is a situation in which there is conflict between an individual's self-interest and the collective interest of the group. Will consumers pursue their own interests or will they act for the good of the entire society? This study takes an innovative approach to explain recycling behaviour through the lens of social dilemma theory. It uses a mixed methods approach that combines both qualitative and quantitative elements in the research design. A phenomenological approach is used to gain a deeper understanding of the recycling experiences of individuals, and survey data is used for quantitative analyses. In the qualitative study, 142 significant statements and eight themes were identified from 20 in-depth interviews. In the quantitative study, data were collected from 332 respondents. Based on the data analysis, the central relationships in the model are supported. There is a positive relationship between the expectation that others will participate in recycling and the likelihood of personal participation in recycling, and there is also a positive relationship between the likelihood of personal participation and recycling behaviour. Of the four moderators considered, only social value orientation is significant. In the latter part of this thesis, the theoretical and methodological contributions and practical implications of the study are discussed.

A process for the detanning of chrome leather wastes utilising tannery effluents

Glaum, Deanne Melanie January 1994 (has links)
The considerable volume of chromium-bearing wastes generated during the process of leather tanning, exacerbated by the potential for trivalent chromium in the wastes to be oxidised to the toxic hexavalent state, has created a major waste disposal dilemma for the tanning industry. While methods are available for the safe and effective treatment of residual chrome-tanning liquors, little has been done to address the issue of the chrome-bearing solid wastes. Given the increasingly stringent environmental compliance standards facing tanneries, unless an appropriate treatment process is developed in the immediate future, the continued use of chromium as a tanning agent could be compromised. Recent investigations have demonstrated the potential of heated alkaline conditions for dechroming these solid wastes. This study expanded upon these considerations and examined the feasibility of utilising the highly alkaline tannery waste effluents as cost-effective, substitute alkaline media. The three effluents considered in this study, classed as lime sulphide liquors, were shown to be capable of dechroming wet blue shavings, with resultant separation of the solid wastes into a protein and a concentrated chromium product. The solubilised protein product contained low chromium concentrations which comply with legal discharge limits. The precipitated chromium product offers opportunity for reutilisation in the tannery. A novel industrial-scale treatment process, based on these investigations, indicated the process to be capable of treating the quantity of shavings produced on a daily basis by a medium to large scale tannery. Application of this method for the dechroming of other chrome-tanned solid wastes was also shown to be feasible.
