The development of a recycling awareness scale for prospective science teachers

The purpose of this study was to develop a scale for measuring prospective science teachers’ awareness of waste recycling. The study was conducted with the participation of 382 prospective teachers attending a university located in northern Turkey. The five-point Likert type scale that was developed contained 82 items relating to prospective science teachers’ awareness of waste recycling. The factor analysis conducted showed that five items had factor loadings below 0.30, and five were cross loading items. Factor analysis was repeated after removing these items. A further 24 items were removed from the list at the end of the factor analysis, and the remaining 48 items were grouped under ten dimensions. The reliability coefficient for the factors extracted varied between 0.717 and 0.805, and the internal reliability coefficient for the whole scale was 0.905.

친환경 배전급 전력케이블용 절연재료의 전기적 특성에 관한 연구 (I)

The cross-linked polyethylene(XLPE) has been most widely used for the power cable insulating layer because of its outstanding properties such as electrical and mechanical properties. However, XLPE is unrecyclable when disposed after replacement and demolishing because it becomes thermosetting through cross-linked process. Recently, because of growing social awareness of recycling and eco-friendly, there is growing need for the development of recyclable insulating materials that can replace XLPE. Therefore, the purpose of this study is to compare the electrical properties of XLPE and recyclable thermoplastic insulating materials. To this end, we compared and analyzed the electrical properties of XLPE and group N2 through AC breakdown test, accelerated water treeing test and accelerated life test(ALT).

FEN BİLGİSİ ÖĞRETMEN ADAYLARININ GERİ DÖNÜŞÜM KAVRAMI HAKKINDAKİ FARKINDALIKLARI

The aim of this research is to examine the awareness of science teacher candidates on recycling. Total 315 teacher candidates studying at first, second, third and fourth grade at the Department of Science Education have participated in the research. An awareness test that comprises of 5 open-ended questions has been implemented to the teacher candidates. It has been determined that the teacher candidates heard about the concept of recycling mostly through school, media and their families. It has also been determined that the teacher candidates are evaluating the recyclable material within the scope of packaging wastes. It has also been determined that despite almost all teacher candidates have the sufficient awareness concerning the meaning, necessity, purpose of recycling, they do not have the sufficient awareness about the recyclable materials. However, it is striking that the teacher candidates have not mentioned metal and composite packaging wastes. Yet, a few teacher candidate is aware of the meanings of the signs besides recycling and recovery signs that are on the packages. It is believed that the reasons behind the limited recycling awareness are lack of knowledge and interest and lack of importance about recycling on media and in education theoretically and practically.

Out of sight, out of mind: Issues and obstacles to recycling in Ontario's multi residential buildings

This study examines the obstacles, barriers and opportunities to household recycling in multi residential buildings in Ontario, Canada. Specifically, this study examines how increasing levels of recycling convenience and recycling awareness affect household recycling behavior and building recycling rates. This study was divided into three phases: Phase 1 was designed to assess the perceived barriers to recycling and household participation in source separation programs among 12 multi residential households in the Greater Toronto Area. Phase 2 involved retrofitting each building with floor level recycling chutes (accompanied by a comprehensive recycling promotion and education campaign) and measure how, if at all, recycling rates changed. Phase 3 of the study examined how an alternative promotion and education strategy (that involved putting a recycling bin in building lobbies) affected household recycling awareness and overall recycling rates. Using waste audit data collected over a 9 month period and semi structured surveys in each of the 12 buildings included in the study, it was found that the greatest increase in recycling rates were observed after putting a recycling cart/bin the building lobby entrance. The installation of recycling chutes alone did not increase household recycling awareness or participation in any meaningful way. This finding contravenes previous investigations into multi residential recycling, which found that convenience was the primary determinant to multi residential recycling participation. There is evidence to suggest that there is a complimentary effect between retrofitting units with recycling chutes and placing a Blue Bin in the lobby entrance—while the former provides the enabling conditions to make recycling easier for households, the latter provides the necessary reminder to residents to get them thinking about recycling initiatives in their buildings.

Level of Recycling Awareness and Responses to On-campus Recycling Facilities: Case Study-Universiti Kebangsaan Malaysia Students

A survey to find out the level of recycling awareness of 400 students at Universiti Kebangsaan Malaysia (UKM), Bangi was conducted. The written questionnaires were focused on evaluation of waste management in UKM, recycling awareness and effective recycling bins design in UKM. The recycling facility was generally well supported, with predominantly positive recycling attitudes and self-reported recycling behaviour indicated for students. As conclusion, the survey conducted shows that the students are ready for recycling activities if the recycling facilities are provided and accessible to them.

Importance of recycling education: a curriculum development at WSU

The use of recyclable materials has been continuously increasing worldwide due to economic, environmental, and technological developments. Not reusing recyclable materials means that they will be degraded or corroded, and then completely destroyed by nature, thus representing a waste of resources and much environmental damage. To increase both academic and public awareness of recycling, the authors have developed a three-credit-hour recycling course entitled “Recycling of Engineering Materials” at the College of Engineering at Wichita State University, which was taught in spring 2008 and 2010. The lectures focused on basic characterization and separation techniques of recyclable materials, recycled products, environmental concerns, and potential commercial applications. Throughout the lectures, students were expected to gain an understanding of recycling concepts, processing techniques, recent progress on recycling, as well as health issues relating to toxic and hazardous materials and their handling procedures. The survey results confirmed that the course is well established and understood by the undergraduate and graduate students.

Cross-cultural comparison of concrete recycling decision-making and implementation in construction industry

Waste management is pressing very hard with alarming signals in construction industry. Concrete waste constituents major proportions of construction and demolition waste of 81% in Australia. To minimize concrete waste generated from construction activities, recycling concrete waste is one of the best methods to conserve the environment. This paper investigates concrete recycling implementation in construction. Japan is a leading country in recycling concrete waste, which has been implementing 98% recycling and using it for structural concrete applications. Hong Kong is developing concrete recycling programs for high-grade applications. Australia is making relatively slow progress in implementing concrete recycling in construction. Therefore, empirical studies in Australia, Hong Kong, and Japan were selected in this paper. A questionnaire survey and structured interviews were conducted. Power spectrum was used for analysis. It was found that “increasing overall business competitiveness and strategic business opportunities” was considered as the major benefit for concrete recycling from Hong Kong and Japanese respondents, while “rising concrete recycling awareness such as selecting suitable resources, techniques and training and compliance with regulations” was considered as the major benefit from Australian respondents. However, “lack of clients’ support”, “increase in management cost” and “increase in documentation workload, such as working documents, procedures and tools” were the major difficulties encountered from Australian, Hong Kong, and Japanese respondents, respectively. To improve the existing implementation, “inclusion of concrete recycling evaluation in tender appraisal” and “defining clear legal evaluation of concrete recycling” were major recommendations for Australian and Hong Kong, and Japanese respondents, respectively.

Problems of Household Waste Disposal

The study was conducted in Palampur, Himachal Pradesh. Multi-stage stratified random sampling was used to draw a sample of 108 respondents. Based on sample survey, the study reveals that the garbage disposal outside the house was a major problem. Polythene was burnt along with other waste in both the communities. Waste recycling awareness was found to be higher in teaching community as compared to non-teaching community.
