Human activities have significantly intensified natural phosphorus cycles, which has resulted in some serious environmental problems that modern societies face today. This article attempts to quantify the global phosphorus flows associated with present day mining, farming, animal feeding, and household consumption. Various physical characteristics of the related phosphorus fluxes as well as their environmental impacts
in different economies, including the United States, European
countries, and China, are examined.

This article explores the potential of RFID (radio frequency identification device) for improving the current waste and resource management system in Switzerland. It presents the following three possible options for utilizing RFID tags to support waste management processes:

At the heart of the original vision for extended producer responsibility (EPR) was the desire for a policy strategy that could provide ongoing incentives for the incorporation of environmental concerns into the design of products. If producers were made responsible for end-of-life management (i.e., reuse, recycling, energy recovery, treatment, and/or final disposal) of products, they would find it in their self-interest to anticipate end-of-life costs and obligations and design their products to minimize those costs.

The

Carbon accounting is now firmly on the agenda of science, politics, and business. Individuals are estimating their

The challenge in working with environmental improvements is to select the action offering the most substantial progress. However, not all actions are open to all actors in a product chain. This study demonstrates how life cycle assessment (LCA) may be used with an actor perspective in the Swedish postfarm milk chain.

The forestry sector is experiencing an increasing demand for documentation about its environmental performance. Previous studies have revealed large differences in environmental impact caused by forestry operations, mainly due to differences in location and forestry practice. Reliable information on environmental performance for forestry operations in different regions is thus important.

In this article the authors have elaborated a consistent framework for the quantification and evaluation of eco-efficiency for scenarios for waste treatment of construction and demolition (C&D) waste. Such waste systems will play an increasingly important role in the future, as there has been for many years, and still is, a significant net increase in stock in the built environment.

Industrial symbiosis (IS) has been used to describe the physical exchange and shared management of input and output materials by geographically proximate firms. Firms that engage in IS are said to belong to an industrial ecosystem.

In North America, consideration of life cycle environmental, economic and social aspects of buildings is in vogue. This trend is clear in part from the booming memberships of the U.S. and Canadian Green Building Councils and Sustainable Buildings Canada and the growing number of buildings and communities using environmental rating systems.
