Human performance principles, indicators, their metrics and information sharing techniques are applied to nanotech sustainability assessment and risk communication in this paper. The purpose is to optimize the nano-risk performance in sustainable nanotech development. The method takes human physical and cognitive capabilities, limitations into consideration during nanotech sustainability modeling...
The existing efforts on carbon footprint studies of manufacturing processes are focused largely on emissions assessment for product compliance reporting. Relatively little attention has been given to analyzing how process properties affect these emissions for carbon footprint reduction. Going beyond assessment calculation into carbon footprint improvement, this paper presents a method for modeling...
Brought into focus by sustainable development along with related issues of resource efficiency and health hazard reduction, sustainability in industrial waste recycling is becoming an emerging area with potentials to contribute to environmental protection, economic development and social benefit. This paper examines a sustainability management approach to the development of sustainable recycling technologies...
This paper reports a double-stage coupled heat pumps (DSCHP) heating system, which couples air source heat pump (ASHP) and water source heat pump (WSHP) together. The system is presented for the first time in open literature with the objective to improve the working condition and heating performance of the ASHP under cold environment. A practical project in Beijing firstly installed this system and...
