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.

ABSTRAKSampah merupakan salah satu faktor kerusakan lingkungan terutama di area kampus yang memiliki banyak timbulan sampah. Salah satu upaya untuk menyelamatkan lingkungan kampus adalah dengan menjalankan program green campus. Untuk menilai kegiatan green campus, Indonesia telah memiliki sistem penilaian yang dikeluarkan oleh Universitas Indonesia yaitu UI GreenMetric, dengan salah satu kategori yang dinilai adalah sampah. Penelitian ini bertujuan untuk mengembangkan indikator pada kategori sampah pada kampus Itenas, Bandung. Data yang diperlukan diperoleh melalui observasi dan studi literatur dan selanjutnya diolah dan dianalisis dengan metode pengembangan atau research and development. Hasil yang didapatkan adalah berupa perkembangan indikator dan sub-indikator yang dapat diterapkan di kampus Itenas yang juga dapat diterapkan di kampus lain.Kata kunci: sampah, green campus, Itenas, pengembangan indikator ABSTRACTWaste is one of the environmental damage factor, especially in campus areas that have a lot of waste generation.

Networks of chemical reactions represent relationships between molecules within chemical supply chains and promise to enhance planning of multi-step synthesis routes from bio-renewable feedstocks. This study aims to identify <i>strategic molecules</i>in chemical reaction networks that may potentially play a significant role within the future circular economy. We mine a commercially available database in order to assemble a network of chemical reactions. We describe molecules within the network by a portfolio of graph theoretical features, and identify strategic molecules with an isolation forest search algorithm. In this work we have identified a list of potential strategic molecules and indicated possibilities for reaction planning using these. This is exemplified by a potential supply chain of functional molecules from bio-waste streams that could be used as feedstocks without being converted to syngas. This work extends the methodology of analysis of reaction networks to the generic problem of development of new reaction pathways based on novel feedstocks.

Cockle Shell

A conspectus based upon a compelling topic, namely, versatility of cockle shell use in concrete to replace partially the natural coarse aggregates and river sand, which is yet to be investigated, is covered in this chapter. An introduction to enlighten the reader with this promising waste material precedes a review of environmental issues with cockle shell which would reduce harm to environment and preserve natural materials for future generation. Cockle trade is an important subtitle that covers cockle shell waste generation, research, and development related to the deployment on the use of cockle shell, processing cockle shell for making construction material are discussed in detail. Experiments were conducted, and the test data revealed that the use of cockle shell as partial replacement of coarse aggregates enhanced the strength of concrete and as partial replacement of sand improved the performance of mortar bricks.
