Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

The prudent management of hazardous materials, from their procurement to their proper disposal, is a critical element of a departmental laboratory safety program. However, it is known that the management of chemical residues involves a high cost and few studies are carried out aiming at assisting in the implementation of this system of management mainly about educational and research institutions. This work therefore presents the economic feasibility analysis in the implementation of the chemical waste management system in laboratories of a Brazilian University. The data were obtained through a questionnaire applied to the technicians of the laboratories generating chemical residues, these being, teaching, research and clinics of the university. The economic-financial analysis has shown that the internal treatment of waste with the construction of a laboratory in the university is an unfeasible project. However, the project is feasible using the already existing structure, such as the chemistry laboratory in the idle periods. In this way, waste treatment on the university campus is feasible, in relation to the costs involved with outsourcing. However, it is necessary to ensure that the chemical standards for sewage disposal, as stipulated by the responsible bodies, are achieved.
