Research On Application

Manufacture is the pillar industry of national economy, yet its efficiency of the utilization of raw materials and energy needs increasing, and the consumption of environment needs improving urgently. From the perspective of material flow management, we introduce the material flow cost accounting (MFCA) to manufacturing enterprises and check computations according to two dimensions: value flow and material flow during the productive process. It can help achieve the goals of cutting the materials costs, saving the resources consumption and lowering environmental impact, thus the manufacturing enterprises can strengthen their competitive power and realize their own development.

Material Flow Management

Within Germany’s industry the issue of environmental protection has increased in importance within recent years. A distinct indicator to support this thesis is the voluntary participation in the implementation of the EMAS by more than 2000 company sites. One reason for this is a shift in the perception of industrial environmental protection over the past years. Previous environmental protection was mostly sensed as a bureaucratic burden. Today, the enterprises take an active part in using environmental protection successfully for achieving company business aims by setting-up environmental management systems. This chapter focuses on the issue of material flow management as an approach to optimise a company’s economical and environmental performance. Material flow management comprises the identification, analysis and optimisation of procurement, usage, handling, transformation and disposal of all physical goods within a company. A physical good in the context of material flow management does not only comprise raw materials and semi-finished products but especially all those materials that have not been dealt with in common management and information systems such as waste, energy, commodities, etc. This chapter describes contents and potentials of material flow management. It especially contains a description of the specification and introduction of an Environmental Management Information Systems (EMIS) which offers special support in the area of material flow management to a machine building company.

Optimum Balance

Corporate logistics a major tool used to facilitate corporate goals. By definition it is a set of tasks, arranged in a way that promotes optimum material, information and value flow during the transformation process. As the above definition implies, the corporate logistics provides visualization of material flow throughout the corporation. Whereas the planning defines what will be produced, the actual production defines the production means. In contrast, the logistics provides for means and measures to ensure production preparedness, providing not only for the actual production of goods but also for a timely and effective information flow in order to achieve optimum balance of all flows in support of corporate objectives.

Environmental threats are triggered by the overconsumption of raw materials. It is therefore necessary to move towards a society that both reduces extraction and keeps the majority of the extracted raw materials in the socio-economic system. Circular economy is a key strategy to reach these goals. To implement it effectively, it is necessary to understand and monitor material flows and to define hotspots, i.e. materials that need to be tackled with the highest priority. This paper is aimed at determining how to increase circularity in the Swiss economy by means of a Material Flow Analysis coupled with a simplified Life Cycle Assessment. After having characterized material flows, we analyzed two types of hotspots: i) Raw materials consumed and/or disposed at high level, and ii) Raw materials whose extraction and production generates high environmental impacts. The Material Flow Analysis shows that each year 119 Mt of raw materials enter the Swiss economy. Therefrom, 15 Mt are derived from recycled waste inside the country; 67 Mt leave the system yearly; 27 Mt towards disposal. Out of the disposed materials, 56% are recycled and re-enter the socio-economic system as secondary materials. Looking at hotspots; concrete, asphalt, gravel and sand are among materials that are consumed and disposed at high level. Yet, looking at greenhouse gas emissions generated during extraction and production, metals - including the ones in electrical and electronic equipment - as well as textiles are among the categories that carry the biggest burden on the environment per unit of material.

Zircon Sand

The radiation impact on the environment from naturally-occurring radioactive materials in zircon sand is an important issue for zirconium product manufacturing enterprises. In this paper, a typical oxychloride production enterprise has been taken as an example to study the radiation effect and environmental pollution during the whole production process. The transfer and enrichment of radionuclides in zircon sand was studied by analyzing their concentrations in samples, such as products and wastes, which were sampled from every studied workshop, so that the dose rate in the environment and typical facility surfaces of each workshop could be measured. The study results show that the transfer and enrichment of radionuclides occur mainly in workshops of acidification, dissolution, concentration and crystallization. Silicon slag adsorbed some radionuclides, but most of the radionuclides in raw materials are transferred and enriched in waste acid by the concentration and crystallization process. Sludge and wastewater still contain a large quantity of radionuclides after treatment by wastewater treatment plants. This results in a significant increase in U-238 and Th-232 concentrations in river water near the main outlet. The average effective dose of all employees in the studied enterprises was 0.94 mSv, and workers from the wastewater treatment plants had the largest annual effective dose at 11 mSv.
