Approximately 300 million tons of plastic waste is generated per year. The major portion of this plastic waste is landfilled, while part of it leaks into the environment. When plastic waste enters the terrestrial or aqueous environment, it can have negative impacts on ecosystems, human health, and wildlife. Increasing the amount of plastic waste that is recycled will correspondingly reduce the amount of plastic waste that enters the environment. By educating the public and industry on plastic recycling, current recycling programs can be used more efficiently, and new programs can be created. Education material on plastic recycling is available through professional and industry associations, foundations with an environmental focus, university courses, and short courses offered with private companies. This review assembles and analyzes the current education material on plastic recycling that is available from these providers. The material compiled here can be used to gain insight into specific plastic recycling-related topics, to identify areas of recycling education that can be improved, and as a resource to help build university level courses. There is currently a dearth of plastic recycling courses offered at the university level. Educating more students on plastic recycling will equip them with the knowledge and skills to make informed decisions as consumers, and to implement plastic recycling systems at the professional level.

Plastic waste is a type of inorganic waste that is difficult to decompose in soil and water. Plastic waste is usually only piled up and disposed of, causing various kinds of negative impacts. One of the efforts to tackle plastic waste in Bontang City is to create a tool that can convert plastic waste into fuel oil. The purpose of this community service is to provide an understanding to the community (students) regarding the dangers of plastic waste to the environment and to provide knowledge to the public about how to process plastic waste into fuel oil using practical and inexpensive pyrolysis technology. The method of implementing this community service activity is in the form of counseling and training. The results of this community service received a very good response from students and teachers. This response can be seen from the enthusiasm of the participants when carrying out the practice of processing plastic waste into fuel oil. The conclusion of this community service has a very positive impact on the processing of plastic waste into fuel oil and changes the habits of the Bontang people, which initially only disposed of plastic waste, then utilized it so that it had economic value.

Plastic Pellets

The high use of plastic products is currently causing uncontrolled accumulation of plastic waste so that an effort is needed to minimize the negative impacts caused to the environment. One of the appropriate efforts in processing plastic waste is recycling to produce a variety of useful products. Each stage of the process in managing plastic waste recycling starts from collecting raw materials to producing a new product for consumers requiring energy that can be calculated and analyzed for their impact on the environment using the LCA method. From this study can be concluded that the plastic recycling industry as one of the efforts in reducing the generation of plastic waste to the environment consists of 3 (three) main stages, namely the stages of enumeration, the distribution of raw materials and the stages of production of plastic pellets. The environmental burden analyzed includes the production process of recycling plastic waste to produce an output in the form of 1 ton of plastic where the total GHG emissions generated are 2.36E + 03 kg CO2 eq, with details of the potential contribution to global warming of 1.30E + 02 kg CO2 eq at the stage enumeration, 3.52E + 01 kg CO2 eq at the distribution stage and 2.15E + 00 kg CO2 eq at the plastic pellets production stage. The efficiency of plastic seed products in this study showed a good result, where the NEV and NER values of the recycled plastic pellets products were 39664.1 MJ and 2.11 MJ.

Technological advances due to the rapid flow of globalization, change the pattern of teaching in the world of education. The philosophy of education shows a vertical relationship, up or down with the branches of education. It is hoped that the public can better understand the importance of globalization so that the negative impacts that have an impact can be minimized and it is also hoped that the realization of positive activities towards education will be even better. Education contributing to the success of development in the agricultural sector is not solely determined by development in the technology sector but is determined by the development of the quality of human resources, aspects of human personality, which include knowledge, values, attitudes and skills. The influence of globalization encourages education in the agricultural sector to be increasingly encouraged by stakeholders to always be improved so that the agricultural sector becomes more productive.

This paper aimed to point out the determinants of the effectiveness of Municipal Management in Brazil. It was a quantitative, descriptive research, with secondary data from 2015 to 2017, available at the Rui Barbosa Institute web site – 11 variables correlated with the effectiveness of management. The sample was comprised of Brazilian municipalities. The results were estimated by logistic regression with balanced panel data and interpreted by the odds ratio criterion. The results showed that population size and the mayor’s reelection have a positive and statistically significant relationship to explain the effectiveness of management. On the other hand, the number of candidates for mayors, and disapproved expenses showed a negative and statistically significant relationship to explain the effectiveness. By addressing the effectiveness of municipal management, this article fills a gap in the literature because it brings to the debate the relevance of the evaluation phase of the public management to improve its quality and/or mitigate negative impacts on the population.

Cutting is the process in which goods or garment material are cut and converted into pattern shapes of the goods or garment components. There are two methods of Leather cutting, which are hand cutting and machine cutting. Hand cutting is done with the use of hand knife, cutting board and cutting patterns. Machine cutting can be done using semi-automatic cutting machines or fully-automatic cutting machines. Currently, in Ethiopia, different local and foreign investors are participating in leather products manufacturing. Most of the leather product manufacturing industry and some Small and Medium enterprise’s (SME’s) in the country are using leather cutting machines in order to cut leather goods or garment parts. Most of the industry and SMEs are using imported cutting board made of plastics and rubbers. However, these cutting boards are expensive.   This research aimed at developing a cutting board made from HDPE (High-Density Polyethylene) plastic waste as main material, calcium carbonate as a filler and glass fiber as a reinforcing material. Primary and secondary data gathering techniques were applied simultaneously. Primary data were collected through interview and field observation. Secondary data was gathered by reviewing different literature. The cutting board developed through collecting HDPE plastic waste, washing, shredding and melting the shredded plastic with filler and reinforcing material. The melted plastic poured in to cutting board mold and cooled. The developed cutting board was compared with HDPE cutting board available in the local market. The developed board showed relative compression and hardness properties with the HDPE cutting board available in the market. In the cost analysis, the developed cutting board is cheaper than the cutting board which available in the market. However, the cutting board in the market has better surface texture and quality than the developed cutting board. Melting HDPE plastic waste using metal or clay cooking pots and charcoal fire is a tedious task and smoke from the fire will cause human health problem and will affect environment. Consequently, manual plastic melting method is not feasible for mass production, because it is difficult to control the amount of heat (charcoal fire) during melting process. Based on this the authors recommend using machine based plastic melting and molding during HDPE and related plastic recycling.

This chapter discusses the rise, largely in the nineteenth century, of a new form of populist authority that expanded the scope of Islamic activity beyond the reach of ever more marginalized courts. Indonesian Islam, supported in some instances by a growing native economy, moves away from court-mandated orthodoxy towards a closer connection with Mecca and the Middle East mediated by independent teachers. In some instances, these independent religious masters were able to prosper and to adapt to new modes of Sufi organization that saw the adoption of the tariqas in favor in the Ottoman Empire. By the century's end, the Naqshbandis in particular were exploring new ways of broadening their constituencies. These included somewhat controversial short-courses of instruction and the dissemination of printed materials that were increasingly available to a pesantren-schooled section of the public.

The increasing global waste plastic pollution is urging people to take immediate actions on effective plastic recycling and processing. In this work, we report the results of processing reclaimed plastic wastes from unsanitary landfill site in Kuwait by using a bench scale continuous auger pyrolysis system. The plastic feedstock was characterised. After a simple thermal densification process, the material was fed to the pyrolysis system at 500 °C. The pyro-oil and wax products were collected and characterised. The process mass balance was developed on dry basis, and the yields of pyro-oil, light wax, heavy wax and gases were 5.5, 23.8, 69.4 and 1.3 wt%, respectively. The findings have indicated that the reclamation of plastic waste from landfill was feasible in terms of the product distribution and characteristics. Further liquid analysis confirmed that the liquid products contained fractions that are comparable to petrol and diesel fuels. The wax products are viable and have potential application as coating, covering and lubrication.

Outsourcing the hazardous materials (HazMat) transportation is an effective way for manufacturing enterprises to avoid risks and accidents as well as to retain sustainable development in economic growth and social inclusion while not bringing negative impacts on the public and the environment. It is imperative to develop viable and effective approaches to selecting the most appropriate HazMat transportation alternatives. This paper aims at proposing an integrated multi-criteria group decision making approach that combines proportional hesitant fuzzy linguistic term set (PHFLTS) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to address the problem of HazMat transportation alternative evaluation and selection. PHFLTSs are adopted to represent the congregated individual evaluations in a bid to avoid information loss and increase the reliability of results. Two weight assignment models are then proposed to determine the comprehensive weights of experts and criteria. Furthermore, several novel manipulations of PHFLTS are also defined to enrich its applicability. The TOPSIS method is subsequently extended to the context of PHFLTSs to rank alternatives and choose the best one. Eventually, the feasibility and validity of the proposed approach are verified by a practical case study of a HazMat transportation alternative evaluation and selection decision and further comparison analyses.
