The design of a steel structure factory is a complex process that requires careful consideration of material flow, workflow efficiency, structural integrity, and safety. Among the most critical elements in such a facility is the placement of overhead cranes, especially double girder overhead cranes, which are widely used for lifting heavy ...
The water budget of the Bangkok Metropolis system was analyzed using a material flow analysis model. Total imported flows into the system were 80,080 million m3 per year (Mm3 y–1) including inflows from the Chao Phraya and Mae Klong rivers and rainwater. Total exported flows out of the system were 78,528 Mm3 ...
It is more than just recycling While substituting secondary materials for primary materials can offer a part solution, recycling offers limited appeal as its processes are energy-intensive and generally downgrade materials, leading to continuing high demand for virgin materials. ...
They need input flows (such as energy, fuel, metal, wood, water, food, materials for building and infrastructure, space) to maintain their vital functions (Decker et al., 2000). After transformation and use, these 'metabolic inputs' are discharged to the environment (atmosphere, water and soils) as 'metabolic outputs' in the form of air emissions, liquid and ...
The proposed policies of the Postmodern Sanitation concept are: (1) to discuss a sanitation value chain that creates and adds value to human excreta, and products made from human excreta, and build a sanitation business model to drive this sanitation value chain; (2) to design a sanitation business model focusing on incentives for individual toilet users; (3) to analyze current users' ...
In the manuscript, MSW sorting options for the eight most populous cities in India are evaluated using simplified material flow analysis. The analysis highlights that ~45–97% of the total MSW can be diverted from landfills by using the proposed schemes. ...
The preliminary results of system screening (identification of problems and drivers) and material flow analysis (MFA) have shown that the reservoir is hypertrophic and the probable drivers are emissions from cattle breading, point sources and erosion from arable land. Apart from first measurements, soft factors and the problem of eutrophication ...
This contribution investigates the relationships between diet and agricultural production, the resulting mass flows of nitrogen and phosphorus, their impact on the aquatic environment, the agricultural area requirements and emissions of nitrogen to the atmosphere in a clearly defined region. The combination of material flow ...
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 ...
This study describes the evolution of sanitation arrangements in the Swedish town Linköping for the period 1870–2000. The flow of phosphorus from food consumption is estimated for the period and its output is divided into gainful reuse in agriculture and energy production and (harmful) losses to the hydrosphere and landfills. ...
More detailed investigations are required in this respect in order to arrive at more specific conclusions and have commenced by an interdisciplinary team led by the authors.Keywords: agricultural pollution, environmental protection, material flow analysis, ...
It aims to identify the most promising mixes of policy instruments for SC and to use Material Flow Analysis (MFA) to model prospective impacts of policies on selected sustainability indicators in Europe and internationally, and to determine best practices of such policies for the next decades.Keywords: sustainable consumption, MFA, ...
This is the main focus of this paper—the establishment of a transparent methodology that accurately measures flows of MSW in the country. The methodology is demonstrated using California as a test case. ...
Recent decades of economic and industrial development have accelerated the demand for and use of construction aggregates in Taiwan. Material Flows Analysis (MFA), the most common analysis tool of the scientific field of industrial ecology, was employed in this study. ...
This paper describes a modelling tool that integrates Material Flow Analysis, energy production and Greenhouse Gas (GHG) emissions accounting for biomass flows at a regional scale. This tool allows comprehensive analysis of alternative systems for management of biomass waste and bioenergy production in regional ...
Platinum group metals have become indispensable in modern industrial society and the demand for PGMs has greatly increased. An in-depth quantitative analysis of PGM applications, lifecycle structure, deficits and optimisation potential in Germany has been carried out by Umicore Precious Metals Refining and Oko-Institute. Besides detailed insights into one of the more opaque metal ...
Material and energy flows (together with human appropriation of land) are considered the key cause of environmental problems. This paper describes the application of economy-wide material flow accounting and analysis to the economy of the Czech Republic for 1990-2002. ...
The creative implementation of these strategies requires knowledge of potential sources of energy and flows of waste. Inventories of requisite data are sparse. Wood and paper are interesting cases in point, as they are significant contributors to waste and potential energy carriers. A better knowledge of all related flows is obtained by means of a ...
Comprehending how humans let toxic cadmium (Cd) loose in their environment demands analysing zinc (Zn) production, the source of most mined Cd. Analysis of unaccounted Cd with the ImPACT identity as a product of population, affluence, intensity of Zn use, and the used fraction of Cd in Zn ore shows that the used fraction exerted the most leverage. ...
At present, however, most of the waste unintentionally becomes dispersed in non-hazardous waste, making it difficult to control the outflows of hazardous substances from preservative-treated sawn timber.Keywords: preservatives, sawn timber, wood waste, waste management, hazardous substances, environmental pollution, material flow analysis, ...
