Waste Management Practices

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 aim of the present study was to create a source separation and waste reduction culture in Ardabil city in a randomized systematic way. The present semi-experimental study was conducted in two regions of Ardabil city. The number of sample in each region was 100 (50 as control, 50 as case population). In order to determine the effect of the profile of households in regions 1 and 2 and the effect of training on the amount of produced waste and the increase of awareness on source waste separation, two-step sampling, before and after training, was conducted in both groups. Beside a questionnaire also was completed before and after training. The results showed the statistically significant relationship between the income and reduction of produced waste in region 1 and 2. In the case group, level of awareness in regions 1 and 2 was changed from low-medium (first step) to medium-high (second step). Also, amount of produced waste was reduced in second steps in the case group. This result indicates the effect of training as an intervention factor, on waste management. Therefore, the desirable education system should be selected according to the status of society and the cultural, social, and economic conditions of each region and it is advisable to use specialized staff with health and environmental views to train citizens in order to source waste separation and waste management.

Eco-efficient rehabilitation of buildings and neighbourhoods should include strategies to reduce the potential environmental impact of buildings under consideration for demolishment. In this case, good construction and demolition (C&D) waste management can represent a doubly eco-efficient approach: advantage is taken of much of the building and the volume of waste is reduced during construction and demolition work. Construction and demolition waste management in emergency situations is a subject yet to be studied in the construction sector. This kind of work, although not very common, involves major building damages and the need for punctual, partial or total demolitions. The amount of C&D waste can be a major problem to deal with, and its management during the critical first phases can determinate the progress of the rehabilitation. Conditioned by a greater number of factors than normal construction works, the lack of time for the identification, quantification, and evaluation of C&D waste renders this type of extremely useful study. In this work, from the case study of the emergency repair of a residential building of 40 dwellings in Seville (Spain) seriously affected by a soil displacement, Generated C&D waste are identified and the waste reduction techniques used are shown. These techniques contributed to achieve the planned objectives and to control in advance the cost. Finally, the most important data, C&D waste quantification and the managing cost are presented in order to serve as reference for similar circumstances in the future because there areno clear references to be used.
