Material flow analysis for management of waste TVs from households in urban areas of Vietnam

In the context of rapid urbanization across Sub-Saharan Africa there is a critical need for more robust decision-making between different ways of providing sanitation services in existing and new peri-urban areas. In several countries, authorities tried to find solutions by developing strategies to address sanitation problems in the form of Strategic Sanitation Plans. In Burkina, Strategic Sanitation Plans have been elaborated and implemented since the 1990s. Fada N'Gourma, a secondary city in Burkina, also adopted a Strategic Plan for wastewater and excreta management in 2006. In this study we use material flow analysis as a decision making tool to verify technology options of the Plan. A model was developed and data was collected in order to assess material and nitrogen flows. The status quo situation was compared to scenario based on the proposals made in the Sanitation Plan. Results show that the technology options which were recommended improved human health in the short term. However, the options led to groundwater pollution in the medium term. Compared to the current situation, matter and nitrogen flows would increase by 7% and 7.4% respectively in groundwater. It is thus concluded that the proposed options will not achieve the Plan's stated objectives of environmental protection.

Organic Waste Management

Kegiatan komposting sampah kota umumnya tidak berjalan sinambung karena kegagalan pasar, lemahnya dukungan pemerintah, lemahnya manajemen dan ketidaklayakan teknik yang digunakan. Penelitian ini bertujuan menyusun konsep metabolisme pengelolaan sampah organik melalui teknologi komposting di wilayah internal perkotaan. Metodologi penelitian ini dilakukan dengan metode kuntitatif dan eksploratif deskriptif melalui analisis matematis, analisis multikriteria pengambilan keputusan, analisis aliran material, dan analisis finansial. Penelitian menyimpulkan bahwa metabolisme pengelolaan sampah organik melalui teknologi komposting di wilayah internal perkotaan adalah metabolism sistem fisik, sosial, dan ekonomi dari kegiatan pengelolaan sampah organik yang bercirikan metabolisme antropogenik untuk keberlanjutan kota sedang. Kata kunci: Pengelolaan sampah organik, metabolisme, aliran material, komposting, analisis multikriteria. AbstractComposting of municipal solid waste activities generally do not run continuously because of market failure, lack of government support, poor management and inability of the techniques used. This study aims to develop the concept of the metabolism of organic waste management through composting technology in internal urban areas. Theresearch methodology was conducted by the method of quantitative and descriptive explorative through mathematical analysis, multicriteria decision analysis, material flow analysis, and financial analysis. The study concluded that the metabolism of organic waste management through composting technology in internal urban areas is themetabolism system of physical, social, economic and environmental of organic waste management activities characterized by anthropogenic metabolism to the sustainability of medium cities. Key words: Organic waste management, metabolism, material flow, composting, analysis of multicriteria

Horizon 2020

The main sources of waste generation are: industry, municipal sector, and agriculture. Municipal waste is solid and liquid waste that arise in households, public utilities (trade, services, handicrafts) and municipal services (e.g. street cleaning and maintenance of green areas). The main aim of this paper are the analysis of the flow of municipal solid waste in Łódź Metropolitan Area, its composition, presentation of the process towards a more selective waste system, and the extraction of biodegradable waste from the MSW. The article is based on a report prepared within the Horizon 2020 project REPAiR “Resource Management in Peri-urban Areas: Going Beyond Urban Metabolism”.

Depth Analysis

The unprecedented technological development and economic growth over the past two decades has resulted in streams of rapidly growing electronic waste (e-waste) around the world. As the potential source of secondary raw materials including precious and critical materials, e-waste has recently gained significant attention across the board, ranging from governments and industry, to academia and civil society organizations. This paper aims to provide a comprehensive review of the last decade of e-waste literature followed by an in-depth analysis of the application of material flow analysis (MFA) and life cycle assessment (LCA), i.e., two less commonly used strategic tools to guide the relevant stakeholders in efficient management of e-waste. Through a keyword search on two main online search databases, Scopus and Web of Science, 1835 peer-reviewed publications were selected and subjected to a bibliographic network analysis to identify and visualize major research themes across the selected literature. The selected 1835 studies were classified into ten different categories based on research area, such as environmental and human health impacts, recycling and recovery technologies, associated social aspects, etc. With this selected literature in mind, the review process revealed the two least explored research areas over the past decade: MFA and LCA with 33 and 31 studies, respectively. A further in-depth analysis was conducted for these two areas regarding their application to various systems with numerous scopes and different stages of e-waste life cycle. The study provides a detailed discussion regarding their applicability, and highlights challenges and opportunities for further research.

Inputs And Outputs

In order to study the development of regional recycling economy, the material inputs and outputs of the eco-economic system in Shandong Province during the period from 1996 to 2009 were systematically analyzed by the material flow analysis(MFA). The results show that, (1)excluding water, material inputs and outputs rose persistently, but both were lower than the rate of GDP growth. (2)Water supply had a turning point in 2003, from 25.239 billion tons down to 21.934 billion tons, followed by the total annual water supply has been maintained at 220 million tons. At the same time the amount of wastewater emissions is increasing, especially domestic wastewater emissions had faster growth and that increased pressure on the regional water environment;(3) Steady increase in material input intensity, material output intensity presented a first increased and then decreased trend, that showed since Shandong Province proposed the strategic planning to develop circular economy, the development of regional circular economy have improved the material utilization efficiency and made a material reduction in output in the case of material input growth achieved. The rapid increase of material input and output efficiency further illustrated the efficiency of resource comprehensive utilization and waste output have been significantly improved.
