Electromagnetic mixed-waste processing system for asbestos decontamination

Construction waste is the most important source for reducing raw material resources. In this regard, many countries conduct large-scale research in developing progressive construction waste utilization technologies and creating highly efficient production equipment. Current experience in this field views the construction waste processing system as a number of interconnected subsystems: organizational and technical preparatory measures; waste collection and sorting; waste containerization, packaging and transportation; waste processing and manufacturing of recyclable resources. Each sub-system consists of a set of measures which characterize the change in material quality and properties. Modeling of the construction waste processing system addresses the task of assessing the actual level of the system and subsystems and determining the condition of the same within certain forecasted time perspectives. For this purpose, the cost vs. revenue comparison tools are used. To develop the construction waste processing system and maintain it in working condition it is important that, early on in the project, a waste classification catalogue and a relevant glossary of terms be compiled with all waste processing contractors having to agree to it and observe it. Also, a data bank containing all the relevant engineering and process documentation shall be drafted and maintained

Hierarchy Process

AbstrakBerbagai macam upaya dilakukan oleh pemerintah untuk menciptakan lingkungan suatu kota yang bersih, diantaranya melalui penyediaan fasilitas sistem pemrosesan sampah sebagai tahapan akhir dalam pengelolaan sampah. Saat ini, Kabupaten Klungkung, Provinsi Bali memiliki 3 alternatif sistem pemrosesan sampah yang dapat diaplikasikan, yaitu: menggunakan tempat pemrosesan akhir sampah (TPA) eksisting Regional Bangli, membangun TPA baru tersendiri untuk Klungkung, dan pemrosesan akhir di Tempat Olah Sampah Setempat (TOSS). Penelitian ini bertujuan untuk memilih sistem pemrosesan sampah yang paling optimal dengan mempertimbangkan 4 kriteria, yaitu lingkungan, ekonomi, sosial dan teknis (analisis multikriteria) dengan menggunakan pendekatan Analytical Hierarchy Process (AHP). Setiap kriteria memiliki beberapa sub kriteria yang dimintakan kepada 35 orang responden yang mewakili 5 institusi pemerintahan daerah terkait untuk dilakukan penilaian perbandingan berpasangan. Penilaian juga dilakukan untuk mengevaluasi setiap alternatif terhadap semua sub kriteria dan kriteria. Secara global, responden lebih memilih pencegahan pencemaran lingkungan (nilai bobot 0,16) sebagai sub kriteria terpenting dari total 13 sub kriteria yang tersedia. Urutan kriteria yang dianggap lebih penting adalah lingkungan (nilai bobot 0,543), sosial (0,181), ekonomi (0,146) dan teknis (0,130). Untuk alternatif pengolahan sampah di fasilitas TOSS dianggap yang paling optimal (total nilai 0,47) disusul TPA Regional Bangli (0,28), terakhir TPA baru (0,25). Suatu alternatif sistem pemrosesan sampah dengan kelebihan dan kekurangan masing-masing harus dipilih yang paling dapat diterima oleh berbagai stakeholder terkait sehingga diharapkan dapat menjadi bagian dari suatu sistem pengelolaan sampah yang berkelanjutan dari suatu kota.AbstractIn order to create a city clean, efforts are taken by government including provision of waste processing system facility as part of waste management system. Recently, Klungkung Regency, Bali Province has 3 alternatives of waste processing system to be applied, namely: utilizing the existing regional final disposal site (TPA) of Bangli, building a new TPA facility dedicated for Klungkung area only, and on-site waste processing facility (TOSS). The study aims to determine the most optimal of waste processing system by considering 4 criteria, namely environment, economic, social and technical (multicriteria analysis) with the help of Analytical Hierarchy Process (AHP). Each criterion having several sub criterions were assessed by 35 respondents representing 5 local government’s institutions by applying pair wise comparison. The asessement were also performed to evaluate the alternatives to the given criteria and sub criterion. In global, respondents preferred to put environmental pollution prevention (weight of 0.16) as the most important among total 13 sub criterions available. Among the criteria, environment (weight of 0.543) was more prioritized than social (0.181), economic (0.146) and technical (0.130) aspects. Other result showed that TOSS (total value of 0.47) was more preferred than existing TPA of Bangli (0.28), and new TPA of Klungkung (0.25). An alternative of waste processing with its advantages and disadvantages should be chosen and acceptable by the related stakeholders, thus the facility becomes part of sustainable waste management system in a city.
