Plastic Recycling

Plastic waste can be handled with several traditional waste management strategies, including landfilling, incineration, and recycling. Several novel strategies for recycling plastic waste have been proposed and researched for practical use, however the sustainability of the novel processes have not been analyzed in detail. This paper outlines a strategy for recycling polyethylene terephthalate (PET) waste through pyrolysis. A sustainability assessment of the process is conducted to analyze the environmental, economic, and social performance of recycling PET waste into crude oil. Environmental performance is evaluated using life cycle assessment, and the ReCiPe, cumulative energy demand (CED), and cumulative exergy demand (CExD) impact assessment methods. Net present value analysis is used to assess the economic impacts of the process. To complete a holistic sustainability assessment, social benefits and impacts are presented through a qualitative review of the process. In addition, an environmental impact analysis of the production of virgin PET using the recovered crude oil is presented and compared with traditional virgin PET production in terms of sustainability performance metrics. CED and CExD impact results emphasize the conceivable evidence of plastic waste as an energy source. The research highlights the use of standardized impact assessment methods to realize the environmental, economic, and social benefits of recycling PET into crude oil. Furthermore, a review of various process improvements broadens the potential for optimization of the novel process to further elucidate the benefits of plastic recycling.

Brownfield Redevelopment ◽

Twenty First Century

Brownfield redevelopment has become increasingly popular in the first part of the twenty-first century (Hollander, Kirkwood & Gold, 2010) because of the environmental, economic and social benefits realized from remediating and redeveloping brownfields. There has been little research conducted regarding the redevelopment of brownfields in smaller cities that do not have the strong market forces that have spurred brownfield redevelopment in locales such as Toronto and other large population centres. Municipalities with mid to low markets may need to take different approaches to redeveloping their brownfields and the current Provincial policies may not meet their needs. The purpose of this study is to investigate brownfield case studies in the cities of Sault Ste. Marie and Brantford, Ontario and offer explanations as to why some redevelopment plans have failed to occur in these communities and yet nearby sites have had success.

With the increasing scrutiny on tailings management and requirements of the ground subsidence control, both the academia and industry are highly advocating the utilization of cemented paste backfill (CPB) in the mining industry. Literature review has shown that there are some studies conducted to evaluate the ecological environment, economic development, and social impact of mining. However, a comprehensive study about the economic benefits, resource benefits, environmental benefits, and social benefits of CPB is still lacking. This study aims to present a comprehensive benefit index system for CPB from four aspects, i.e., economy, resource, environment, and society. Questionnaires from experts and the mining industry using CPB technology were collected, and structural equation modeling (SEM) was used for data analysis. The relationships between economy, resource, environment, and society were analyzed. The results show that resource benefits have the greatest impact on the comprehensive benefit of CPB in the mining industry, followed by environmental, economic, and social benefits. According to relevance ranking, resource benefits are positively correlated with social, environmental, and economic benefits, whereas environmental, resource, and social benefits have correlation with economic benefits in turn. Therefore, resource, environmental, economic, and social benefits in order directly affect the comprehensive benefit of CPB on the basis of the influencing degree. Moreover, resource, environmental, and social benefits indirectly affect the comprehensive benefit of CPB. The research findings of this study would help the mining industry popularize the CPB technology and promote the sustainability and cleaner production of the mining industry.
