The aim of this study was to assess the economic and environmental advantages of implementing reverse logistics to recycle solid waste from construction companies. The adopted research method was based on a systematic literature review and two case studies. For the economic assessment, the return on investment, the internal rate of return, and the discounted payback factors were considered, while the material intensity factor was used for the environmental impact assessment. This study shows that there are economic and environmental advantages associated with the use of reverse logistics for solid waste treatment and recycling. In 2016, the purchase of recycled blocks resulted in a profit of over US$45,000 for one company, and another company earned almost US$250,000 in the same year by recycling solid waste from manufacturing blocks and selling iron, wood, paper, and plastics. Furthermore, the environmental impact was reduced. This paper contributes to the dissemination of knowledge regarding the advantages of adopting reverse logistics for recycling construction and demolition waste, and creates new opportunities for companies.

With rapid industrialization, continuous economic development, increasing population and living standards, the amount of general industrial solid waste generated in Kunming has increased continuously from 2001 to 2011. In 2013, the total general industrial solid waste generation was 33.19 million tons, deceased by 9.59% over 2011. The disposal and comprehensive use amount of general industrial solid waste in Kunming has increased dramatically from 2001 to 2013, and the disposal and comprehensive use rate of industrial solid waste increased fast from 64.39% in 2002 to 97.68% in 2013,but the comprehensive use rate of general industrial solid waste has not increased largely. Kunming’s general industrial solid waste treatment capacity has obvious difference from generation capacity, the produced industrial solid waste each year has the utilization of nearly 40%, with about 60% of the solid waste we cannot use. The disposal and comprehensive use rate of general industrial solid waste is different in different region of Kunming. Although the resource utilization of general industrial solid waste has made some progress in Kunming, the technical level is still very low compared with developed region, specially, the comprehensive utilization rate of phosphogypsum and tailings was not beyond 17% in 2013. Thereafter, much still can be done to improve the treatment and disposal of industrial solid waste in Kunming.

Solid Waste Pollution Control is one of the main special courses offered to students whose major is Environmental Engineering. It aims to let students know basic knowledge and control technologies of solid waste pollution, so that they can solve problems on solid waste treatment and disposal. With increasing generation of solid waste (municipal solid waste and industrial solid waste) in China, solid waste control becomes one of the focus environmental problems facing our country, which depends on efforts of environmental professionals. Solid waste control technology has seen a fast development in recent years. In order to keep up with solid waste control nowadays, it is necessary to develop this course to improve teaching effects. Based on analysis of the current conditions of this course, the paper offers a construction plan for the course in the following aspects: adjustment of the course teaching content, enrichment of teaching methods and teaching mode, preparation of test database and exercise database and suggestion of ways to increasing teaching effect of this course.
