The purpose of this report was to find out if grocery stores in Örnsköldsvik and Kramfors municipality recycle their producer responsibility package waste, hazardous waste and their food waste and in what way they get rid of their waste. Are there any differences in how these two municipalities does it? Are there any variance between different stores depending on size, location and finally come up with suggestions for improvements. To find out the answer to this questions phone interviews with 25 grocery stores in these two municipalities were conducted. The results from the survey shows that grocery stores in both municipalities sort out their producer responsibility package waste and hazardous waste to a great extent. Only four stores indicated that they sorted out food waste. Responses were varied regarding in what way the grocery stores get rid of their waste. Some stores get their waste picked-up by the municipality and others by different entrepreneurs. One of the big food chains have a contract with an entrepreneur to pick up their waste at all the stores in this part of the country. Some of the suggested improvements are to minimize the amount of food waste that gets thrown away and clarify the laws on what waste that the municipality have monopoly on. The conclusion of this report is that grocery stores in these two municipalities are good at sorting out their waste except food waste.

This dissertation investigates informal waste recycling practices in the modern urban centre of Buenos Aires, Argentina. My research sets a baseline for the living and working conditions of the approximately 9,000 informal recyclers (cartoneros) in the city, focusing on their health, socio-economic status, and access to social and material resources. The research methods included a survey (n = 397) and interviews (n = 30) with cartoneros, as well as key informant interviews and an analysis of newspaper articles addressing informal recycling in the city. My findings indicate that Buenos Aires’ cartoneros, while not the poorest of the poor, are of a relatively low socio-economic status. Their health outcomes and determinants of health are poor compared to others in the Greater Buenos Aires region, and these workers are often stigmatized and discriminated against because of their associations with waste. Cartoneros’ experiences of the city are characterized by a series of social, political, and physical exclusions, revealing a state of urban inequality in Buenos Aires. I argue that municipal agendas of neoliberal urban development are implicated in both the symbolic and physical marginalization of these workers. Cartoneros draw upon many resources in coping with the multiple vulnerabilities that they face (particularly social resources and assets derived from their labour). They also occasionally engage with urban processes of exclusion through collective action and rhetorical redefinitions of their role in society. These workers are therefore active agents in their own destinies, and potential actors for social change. The municipal government of Buenos Aires has recently implemented a formalization plan for some of the city’s cartoneros; the dissertation includes an assessment of these plans, as well as recommendations for other policy-based interventions to informal recycling practices.

Social entrepreneurship, which can be described as the application of market-based approaches to societal and/or environmental problems, represents a collision between good intentions and the pursuit of profitability. Nearly two decades ago, the democratically elected African National Congress inherited a country in crisis. Neoliberal policies have since promoted the role of the private sector in economic and social development in South Africa. Entrepreneurship is seen as a tool to stimulate poverty alleviation, address staggering unemployment rates and integrate blacks into the mainstream economy. Municipalities are increasingly turning to alternative service delivery, privatization and public-private partnerships to address service delivery crises. Moving beyond traditional methodological approaches of individual case studies, this research adopts a holistic analysis of the recycling sector, which allows reflections on the state and implications of (social) entrepreneurial approaches. Particularly, this research is concerned with the opportunities and limitations afforded by entrepreneurial approaches, including the extent to which contextual variables are acknowledged and unequal power dynamics are challenged or further entrenched. Grounded in entrepreneurship and business theory, this research also pulls from waste management literature, global development, critical and gender studies. Various methodological inquires are undertaken, including structured and semi-structured interviews of participants of recycling initiatives and management of sector organizations, content analysis, and the facilitation of a Recycling Forum. Findings suggest that while there are some opportunities, (social) entrepreneurial approaches are significantly hindered by a lack of acknowledgement of contextual variables and critical investigation into the institutional structures and biases that create particular gendered entrepreneurial spaces. Initiatives risk entrenching apartheid-era inequalities and further disadvantaging the most vulnerable through the creation of competition. The emphasis on recycling deflects efforts from more immediate or hazardous challenges and is insufficient to challenge market inequalities. Moving beyond a guise of good intentions, social entrepreneurship is suggested as a reflective and iterative process that promotes greater self-awareness of one’s impact on the existing value chain, power dynamics and social justice. / Thesis (Master, Environmental Studies) -- Queen's University, 2013-09-20 21:17:33.868

Mondi Ltd. operates a deinking plant at its Merebank mill. The plant recycles 85 000 tons per annum of flat news and magazine to produce a furnish for its newsprint papermachines. A review of the relevant pulping and flotation chemistry literature revealed that the role played by sodium silicate appears to be multi-faceted and in some dispute. Sodium silicate has an undisputed role in pH buffering, hydrogen peroxide stabilisation and the prevention of fibre yellowing. However, its role in deinking is said to be that of an ink collector or alternatively an ink dispersant. The mill's own experience has shown that the sodium silicate plays a vital role in the deinking process. Sodium silicate's ability to disperse ink, both alone and in the presence of calcium ions and fatty acid soaps, was investigated using a model ink system. A representative newsprint ink base was dispersed in the laboratory under conditions similar to those encountered in a deinking pulper. The resultant dispersions were studied using turbidity and particle size analysis. The morphology of the ink particles was determined using a scanning electron microscope. Sodium silicate proved to be a poor disperser of ink particles, but nevertheless appeared to greatly influence the dispersing properties of the soap in the presence of calcium ions. The nature of the interactions between sodium silicate, calcium ions and the collector soap were studied in an attempt to elucidate the role of sodium silicate. A model system consisting of the sodium salt of collector soap, calcium ions and sodium silicate was studied under the conditions that prevail in a typical newsprint deinking pulper. It was found that the soap and the sodium silicate compete for the calcium ions, and sodium silicate showed a measurable chelating e:ffect on calcium ions. Thus, increasing levels of sodium silicate lead to an increase in the concentration of sodium soap in solution. It was hypothesised that this effect would lead to better dispersion of ink particles and improved deinking performance. This chelating effect was evaluated in laboratory deinking studies. Samples of newsprint were pulped in a 251 Lamort laboratory pulper under a variety of conditions, viz. with fresh water, with an excess of soap, with an excess of calcium, with and without sodium silicate. The pulps were floated in a 201 flotation cell. The brightness and colour of the unfloated and floated pulps were measured. The level of the final brightness after flotation was taken as a measure of deinking efficiency. The highest final brightness was achieved when there was an excess of sodium soap and a low Ca hardness in the pulper. Softening the water used in pulping without adding excess sodium soap did not significantly improve pulp brightness. The lowest final brightness occurred in the presence of an excess of calcium in the pulper. Calcium in the pulper in the presence of sodium silicate did not result in a significantly lower final brightness. The results support the hypothesis that sodium silicate sequesters the soluble calcium in a pulping system, thereby increasing the sodium soap concentration and the resultant deinking performance. Apart from sodium silicate's chief role as a peroxide stabiliser, the sequestering action on calcium appears to be its main mechanism of action in a deinking system. An appreciation of this role will facilitate the optimisation of deinking systems with respect to calcium hardness and silicate concentration. To this end it was recommended that the Merebank deinking plant should evaluate the use of water with a low calcium ion concentration and the addition of some soap into the pulper to improve their deinking plant performance. / Thesis (M.Sc.)-University of Natal, Durban, 2003.

According to the Constitution of South Africa, the government is required to make all the infor-mation in the ten indigenous languages of South Africa (excluding English), available to the public. For this reason, the government made the information, that already existed for these ten languages, available to the public and an effort is also been made to increase the amount of resources available in these languages (Groenewald & Du Plooy, 2010). This release of infor-mation further helps to implement Krauwer‟s (2003) idea that there is an inventory for the mini-mal number of language-related resources required for a language to be competitive at the level of research and teaching. This inventory is known as the "Basic Language Resource Kit" (BLARK). Since most of the languages in South Africa are resource scarce, it is of the best in-terest for the cultural growth of the country, that each of the indigenous South African languages develops their own BLARK. In Chapter 1, the need for the development of an implementable named entity recogniser (NER) for Afrikaans is discussed by first referring to the Constitution of South Africa’s (Republic of South Africa, 2003) language policy. Secondly, the guidelines of BLARK (Krauwer, 2003) are discussed, which is followed by a discussion of an audit that focuses on the number of re-sources and the distribution of human language technology for all eleven South African languages (Sharma Grover, Van Huyssteen & Pretorius, 2010). In respect of an audit conducted by Sharma Grover et al. (2010), it was established that there is a shortage of text-based tools for Afrikaans. This study focuses on this need for text-based tools, by focusing on the develop-ment of a NER for Afrikaans. In Chapter 2 a description is given on what an entity and a named entity is. Later in the chapter the process of technology recycling is explained, by referring to other studies where the idea of technology recycling has been applied successfully (Rayner et al., 1997). Lastly, an analysis is done on the differences that may occur between Afrikaans and Dutch named entities. These differences are divided into three categories, namely: identical cognates, non-identical cognates and unrelated entities. Chapter 3 begins with a description of Frog (van den Bosch et al, 2007), the Dutch NER used in this study, and the functions and operation of its NER-component. This is followed by a description of the Afrikaans-to-Dutch-converter (A2DC) (Van Huyssteen & Pilon, 2009) and finally the various experiments that were completed, are explained. The study consists of six experiments, the first of which was to determine the results of Frog on Dutch data. The second experiment evaluated the effectiveness of Frog on unchanged (raw) Afrikaans data. The following two experiments evaluated the results of Frog on “Dutched” Afrikaans data. The last two experiments evaluated the effectiveness of Frog on raw and “Dutched” Afrikaans data with the addition of gazetteers as part of the pre-processing step. In conclusion, a summary is given with regards to the comparisons between the NER for Afri-kaans that was developed in this study, and the NER-component that Puttkammer (2006) used in his tokeniser. Finally a few suggestions for future research are proposed. / MA (Applied Language and Literary Studies), North-West University, Vaal Triangle Campus, 2013

This thesis analyze the impact on recycling from the increase in the deposit on metal cans that took place in Sweden, September 2010. This is done by using a fixed effects model, fixed on municipality, month, and year. Additionally, the thesis investigates the response of different socioeconomic groups to this change by investigating the interaction between deposit and variables for the socioeconomic factors of interest. Interactions for income, education, immigration, environmental awareness, and population density are investigated. The results show that, on avarage, the recycling in each of the Swedish municipalities have increased by 24.739 units per month, this represents an elasticity of recycling with respect to container deposit of 0.04. The results further indicate that there is strong negative interaction between deposit and income, suggesting that as income increases, the individual will be less responsive to a change in deposit. Contrary to theory, the results indicate positive interaction between deposit and education, indicating that, as education increases the individual becomes more responsive to a change in deposit.

This project was a case study with a Local Authority (Charnwood Borough Council, Leicestershire) to research the options in response to the challenges of managing household waste. This research focused on establishing and analysing methods of improving the sustainability of household waste management operation within a Waste Collection Authority, where the interaction with a variety of external and internal stakeholders meant a holistic approach was needed. Waste management practices and performances in Charnwood were evaluated and benchmarked against national standards and the demography of a semi-rural Borough. Waste management practices nationally were also reviewed. The performance of the LA was quantitatively compared with other UK LAs where higher recycling performances are achieved. Differences were separate food waste collection and treatment; a larger proportion of urban housing and the university with a transient population. Other differences included strategy and operational practices for garden waste, the storage, collection, transportation and treatment of waste. A time series statistical model was modified and applied to investigate long term waste generation trends from the Boroughs official waste data returns to Defra. These were used to assess the success of interventions undertaken. This statistical model was able to differentiate interventions that were able to achieve lasting improvements in either waste minimisation or recycling. The declaration of a Zero Waste Strategy was to capture the public imagination. A series of focus groups and public consultations were held to judge public reaction and develop and refine the strategy. These were used to adapt the Zero Waste idea to suit the local conditions. A major conclusion was that householder involvement would be crucial for successful implementation of the further separation of waste that would be required.
