The efficiency and eco-efficiency of manufacturing

In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10, while conventional processes are of order 10. However, many of t...

Sustainable Agricultural Development – Concepts, Principles, Eco-efficiency, Eco-equity, Eco-conditioning

* E-mail: [email protected] ABSTRACT Starting with the reform of 1999 (named Agenda 2000), the Common Agricultural Policy has two main directions: market policy and sustainable development of rural zones. Since 2003, the environmental aspects were better integrated into the agricultural policy that included new measures or improvements of the existing ones, in order to promote the environment p...

Eco-Efficiency Evaluation Considering Environmental Stringency

This paper proposes an extended data envelopment analysis (DEA) model for deriving eco-efficiency. In order to derive eco-efficiency, the proposed model utilizes the concepts of operational efficiency and environmental efficiency. Since DEA can separately measure operational efficiency and environmental efficiency, the treatment for constructing the unified indicator is required to ultimately e...

Eco-Efficiency Indicators for Urban Transport

This paper focuses on urban passenger transport eco-efficiency, which can be defined as the production of maximum benefits to society while minimising environmental impacts from urban transport’s inputs of energy and materials. Researchers have intensively studied transport’s varied environmental impacts, particularly through Life Cycle Assessment; this paper argues that primary transport energ...
