Lifespan is an essential parameter for the accounting and analysis of material stocks and flows, one of the main research topics in industrial ecology. Lifespan is also important as a parameter that portrays the current and historical situation of industrial metabolism, which is an area of interest to industrial ecologists. 

Prospective Models of Society’s Future Metabolism: What Industrial Ecology Has to Contribute

A new family of prospective models is available to study the potential effect of sustainable development strategies at full scale through forward-looking or prospective computer models of society’s metabolism and the natural environment.

Dynamic Modelling of Material Flows and Sustainable Resource Use: Case Studies in Regional Metabolism and Space Life Support Systems

Sustainable resource use is one of the most important environmental issues of our times. It is closely related to discussions on the 'peaking' of various natural resources serving as energy sources,

A general data model for socioeconomic metabolism and its implementation in an industrial ecology data commons prototype

A general data model can be used to structure all data that can be located in the industrial system, including process descriptions, product descriptions, stocks, flows, and coefficients of all kind, which can be implemented by individual researchers, groups, institutions, or the entire community.

Role of Forest Products in the Global Carbon Cycle: From the Forest to Final Disposal

This chapter reviews the role of the production, use and end-of-life management of harvested wood products (HWPs) in the global carbon cycle. Harvested wood products can be long term reservoirs of

Long-Term Sustainability of Copper and Iron Based on a System Dynamics Model

: Copper and iron are critical to the economic growth of modern society. Nations depend on these metals for the development of infrastructure, transportation, and other industries. However, concerns

Anthropogenic Carbon Stock Dynamics of Pulp and Paper Products in Germany

Carbon‐based materials (CBMs) for energetic and material purposes combine biogenic and anthropogenic carbon cycles. In the latter, numerous manufactured products with various in‐use lifespans

Rapid growth of industrial nitrogen fluxes in China: Driving forces and consequences

Human activities are strongly modifying the global nitrogen (N) cycle through increasing input, N species diversity, and pool size of industrial reactive N (Nr). However, the fluxes, fates and

Metal life cycles define and quantify the rates of supply and demand for metals currently used in modern society. Each metal life cycle stage is potentially influenced by material transformation



Lifespan of Commodities, Part II

Any of the four methodologies are theoretically applicable and provide the same value of a lifespan; however unless accurate data such as census statistics are available, lifespan data can vary, and therefore the authors must be very cautious about the representativeness of sample data.

In-use stocks of metals: status and implications.

Comparison of the per capita stocks in more-developed countries with those in less- Developed countries suggests that if the total world population were to enjoy the same per capita metal stock levels as the more- developed countries, using a similar suite of technologies, the amount of global in-use metal stocks required would be 3-9 times those existing at present.

Metals in society

These two volumes provide an authoritative overview of all the major environmental topics. Focusing on the current 'state of the art' as well as the examination of future perspectives. The first

Urban Metal Management The Example of Lead

The metal metabolism of an urban region, the City ofVienna, was investigated to discuss urban metal management strategies in view of environmental protection and resource conservation. About 90% of

Does Soil Acidification Affect Spruce Needle Chemical Composition and Tree Growth?

In 1994, a large survey of soil chemistry was undertaken in thecounty of Värmland in central Sweden (Lundström et al., 1998).The southern part of the county was affected by soilacidification whereas

Accounting for Steel Stock in Japan

During the last two decades, the total material input in Japan has been about 2 billion tons per year, and approximately 50%, i.e., about 1 billion tons, has accumulated as the net addition to stock
