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.

ABSTRAKKota Cimahi merupakan salah satu kota di Jawa Barat yang masih menghadapi permasalahan persampahan, seperti terbatasnya penerapan kegiatan pemilahan sampah, terbatasnya jumlah Tempat Penampungan Sementara (TPS), terjadi pembuangan sampah secara sembarangan ke sungai, terdapat penanganan sampah dengan cara dibakar dan ditimbun, dan lain-lain. Dalam menindaklanjuti berbagai permasalahan sampah tersebut serta mencapai target 30% pengurangan sampah yang ditentukan oleh Kebijakan Strategis Nasional (Jakstranas), maka diperlukan suatu instrumen yang mampu menganalisis area berisiko berdasarkan tingkat risiko persampahan per kelurahan di Kota Cimahi. Area berisiko tersebut digambarkan dalam bentuk peta dengan mengacu pada pedoman Strategi Sanitasi Kabupanen/Kota (SSK) 2018. Area berisiko dinilai melalui skor 1 s.d. 4 secara berturut-turut untuk risiko sangat rendah, rendah, tinggi, dan sangat tinggi. Skor tersebut diperoleh dengan mengalikan parameter Impact dan parameter Exposure. Hasil penelitian ini menunjukkan terdapat tiga kelurahan dengan risiko persampahan sangat tinggi, yaitu Kelurahan Cibeureum, Setiamanah, dan Padasuka serta satu kelurahan dengan risiko persampahan tinggi, yaitu Kelurahan Melong. Penambahan jumlah unit pengolahan direkomendasikan di beberapa kelurahan sehingga terjadi perubahan skor area berisiko.Kata Kunci: Kota Cimahi, Peta Area Berisiko, Persampahan ABSTRACTCimahi City is one of the cities in West Java that still faces solid waste problems, such as the limited implementation of waste sorting activities, the limited number of temporary shelter sites, the indiscriminate waste disposal on river, open burning of solid waste, etc. In following up on these various waste problems and achieving the target of 30% waste reduction determined by the National Strategic Policy, an instrument is needed to analyze risk areas based on the level of risk of solid waste per village in Cimahi City. These risk areas are depicted in the form of maps by referring to the 2018 District/City Sanitation Strategy Guidelines. Risk areas are assessed through a score of 1 s.d. 4 for very low, low, high and very high risks. The score is obtained by multiplying the Impact parameters and Exposure parameters. The results of this study indicate that there are three villages with very high risk of solid waste, namely Kelurahan Cibeureum, Setiamanah, and Padasuka and one village with high risk of solid waste, namely Kelurahan Melong. The addition of the number of processing units was recommended in several villages so that changes in the score of risk areas occurred. Keyword: Cimahi City, Map of Risk Areas, Waste Solid

Estimation of construction and demolition (C&D) waste amount is crucial for implementing waste minimization program. Estimation of C&D waste amount generated is a mean in assessing the potential for waste reduction. Thus, a better understanding of C&D waste generation in terms of causes and sources can be achieved. The aim of this paper is to conduct a review on available construction waste quantification methods from previous studies, which have been utilized in certain countries, while attempting to choose the most suitable and applicable method, and to direct future studies for better quantification methods. This review is applicable only for building construction projects and did not include civil/infrastructure, demolition, renovation, and excavation projects. Six quantification methods and/or waste audit tool available from literatures are discussed, which include their limitation and future direction for this study. It is believed that some combination of these quantification methods could make a good impact in accurate numerical estimation of construction waste amount generated in building construction projects. A strong and accurate database as presented by Soliz-Guzman, combined with effective, vital, and resourceful estimation suggested by Jalali’s Global Index (GI), also with the aid of user-friendly software tool like the SMARTAudit could provide an effective and reliable waste quantification.

Currently, the problem of waste reduction is a permanent concern for all countries of the world, given the need to ensure the sustainability development. In this context, the research aims to highlight the impact of education and demographic factors by residence areas on the long-term behavior of the amount of waste generated in 29 European countries during 2013–2017. The study is based on statistical and econometric modeling aimed at identifying, testing and analyzing the existence of long-term correlation between the amount of waste per capita recorded in each country and four factors of influence considered significant for waste reduction: Pupils and students by education level and Classroom teachers and academic staff by education level, representing exogenous variables which quantify the educational outcomes, as well as The population by degree of urbanization (cities, rural areas), as demographic factors. As a result of an analysis based on correlation and regression method, a cointegration relationship between the analyzed variables was identified. Considering the amount of waste as an important component of the environmental pressure, the obtained results show the significant long-term effect that education and the demographic factor can have on its long-lasting behavior, as well as the ways through which these factors can act to strengthen sustainability.

The Impact

After the airport is put into operation, a large amount of wastes generated every day will bring waste disposal pressure and ecological environment pressure to the airport and surrounding areas. This article expounds the current methods of airport waste disposal. According to the principle of waste reduction, harmless and reclamation, a set of solid waste gasification methods suitable for airports are proposed, which can reduce waste transportation and landfill costs, effectively control the impact of environmental pollution. At the same time, it can use waste heat to generate electricity to turn wastes into treasure and promote green airport construction.
