<p>We apply systems engineering principals and life cycle analysis (LCA) to municipal waste supply chains to elucidate sustainability incentives. Environmental impacts are quantified using LCA for waste management technologies available in the supply chain, and included as products. The supply chain is modeled as a coordinated market and resolved using mathematical optimization techniques. Incorporating impacts as products allows us to analyze the influence of tax policy on optimal waste management strategies.</p>

Landfilling of organic waste is still the predominant waste management method in Canada. Data collection and analysis of the waste were done for the case study city of Montréal in Canada. A life cycle assessment was carried out for the current and proposed waste management system using the IWM-2 software. Using life cycle assessment results, a non-dominated sorting genetic algorithm was used to optimize the waste flows. The optimization showed that the current recovery ratio of organic waste of 23% in 2017 could be increased to 100% recovery of food waste. Also, recycling could be doubled, and landfilling halved. The objective functions were minimizing the total energy consumption and CO2eq emissions as well as the total cost in the waste management system. By using a three-objective optimization algorithm, the optimized waste flow for Montréal results in 2% of waste (14.7 kt) to anaerobic digestion (AD), 7% (66.3 kt) to compost, 32% (295 kt) to recycling, 1% (8.5 kt) to incineration, and 58% (543 kt) to landfill.

Pengelolaan sampah rumah tangga masih menjadi salah satu masalah serius yang terjadi di kota besar. Pertambahan jumlah penduduk setiap tahunnya akan mempengaruhi volume, jenis dan karakteristik sampah yang dihasilkan setiap harinya. Dari hasil penelitian lapangan yang dilakukan di Kecamatan Semarang Tengah pada Tahun 2017 menunjukkan bahwa sampah yang dihasilkan mencapai hampir 0,98 kg  per orang setiap harinya. Adapun sampah yang dihasilkan terdiri dari  77,5 % sampah organik, 13,5 % sampah plastik, 5,5 % sampah kardus dan kertas, 2,2 %  logam / kaleng dan sisanya adalah kaca dan lainnya. Dari komposisi tersebut, sampah plastik merupakan sampah non organik yang memiliki prosentase tertinggi.  Subjek dalam penelitian ini adalah pelaku dalam rantai pasok pengelolaan sampah plastik. Dari subjek penelitian juga didapatkan faktor internal dan eksternal yang akan digunakan untuk menganalisis  kekuatan (strengths), kelemahan (weaknesses), peluang (opportunities), dan ancaman (threats) dalam meningkatkan dan menjaga keberlanjutan pengelolaan sampah plastik di Kecamatan Semarang Tengah.  Suatu sistem penyediaan bahan baku, proses produksi hingga proses pemasaran sampai ke tangan konsumen, dibutuhkan dukungan teknologi baik berupa aplikasi sederhana yang memberikan informasi tentang ketersediaan jenis dan jumlah bahan baku yang terupdate, sehingga dapat mempersingkat waktu produksi. Selain itu juga perlu dukungan sistem informasi untuk membantu pemasaran produk daur ulang, sehingga jangkauan pengguna / konsumen akan lebih banyak dan lebih luas. Keberadaan teknologi informasi memegang peranan penting sebagai media untuk mempercepat terpenuhinya supply dan demand serta menjamin keberlangsungan dan keberlanjutan usaha.STRATEGY FOR DEVELOPING SUPPLY CHAIN MANAGEMENT IN PLASTIC WASTE PROCESSING  ABSTRACT Household waste management is still one of the serious problems that occur in big cities. The increase of population each year will affect the volume, type and characteristics of waste produced every day. From the results of field research conducted in the District of Central Semarang in 2017 showed that the waste generated reached almost 0.98 kg per person every day. The waste generated consists of 77.5% organic waste, 13.5% plastic waste, 5.5% cardboard and paper waste, 2.2% metal / can and the rest is glass and others. From the results showed that plastic waste is non-organic waste which has the highest percentage. The subjects in this study were actors in the supply chain of plastic waste management.  The research subjects also obtained internal and external factors that will be used to analyze strengths, weaknesses, opportunities and threats in improving and maintaining the sustainability of plastic waste management in Central Semarang District. A system of supplying raw materials, the production process to the marketing process up to the hands of consumers, technology support is needed in the form of a simple application that provides information about the availability of types and quantities of updated raw materials, so as to shorten the production time. It also needs the support of information systems to help marketing recycled products, so that the coverage area of users / consumers will be more and wider. The existence of information technology plays an important role as a medium to accelerate the fulfillment of supply and demand and to ensure the sustainability of the business.

Community-based  waste  management  is a form  of  waste  management  recommended  by  the government because  it  is  very  effective  in  creating  a  zero-waste  society.  In  Indonesia,  community-based  waste management can be realized through the development of waste banks at the neighbourhoodlevels. In 2019, the City of Semarang has 48 units of active waste banks. Waste that is managed by the wastebank is plastic, paper and metal. However, there is organic waste which is also managed by several wastebanks. The purpose of this study is to identify and analyze the flow of waste through community-basedwaste management, in this  case of the  waste  bank,  in  the  city  of  Semarang.  The  method  used  is  in-depth  surveys  and  interviews related to the waste bank management system in the city of Semarang. The results showed that the activity of the existing garbagebank was able to reduce waste in the city of Semarang by 0.07% of the total garbage generation  in  the  city  of  Semarang.  This  research  can  be  used  as  a  reference  for  developing  better community-based waste management strategies, especially in Semarang City
