Sentence examples for material cycles and from inspiring English sources

The sustainable utilisation of natural resources requires a new focus on optimal material cycles and material efficiency.

Understanding the relationship between material cycles and economic growth is essential for relieving environmental pressures associated with material extraction, production, and consumption.

This method compares anthropogenic and natural flows according to the following sustainability criteria [17]: Principle 1: Anthropogenic mass flows must not alter global material cycles and; Principle 2: Anthropogenic mass flows must not alter the quality of local environmental compartments.

Product design selects materials from primary metal and material cycles and combines them into multi-material designs, in which the various materials (metals and non-metals) are complexly integrated (e.g. welded, glued, alloyed, layered).

Thus, the overturning can contribute to the material cycle and subsequent biological productivity through the supply of nutrients such as iron.

Soil ecological process is an important part in the material cycle and energy flow of terrestrial ecosystem and is closely related with vegetation development and succession (Wardle et al. 2004; Noah and Robert 2006).

An international collaborative study is examining the back-end of the fusion materials cycle and the different options for the management of irradiated material.

CO2 total emissions are estimated for both fuel life cycle and cradle-to-grave materials cycle and, based on the electricity consumption, the impact of these vehicles on the electric grid and the cost assessment on production and use such as maintenance and fuel price is estimated.

Eugene Odum, a founder of ecology, defined an ecosystem as: "Any unit that includes all of the organisms...in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity and material cycles (ie: exchange of materials between living and nonliving parts) within the system".

Eugene Odum, a founder of ecology, stated: "Any unit that includes all of the organisms (ie: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e.: exchange of materials between living and nonliving parts) within the system is an ecosystem".

Having outlined briefly the core arguments of sustainability, the hierarchy of end-of-life disposal and open and closed material cycles, it then posits the central argument of the book that the design function is responsible for improving sustainability in an engineered product or machine.
