Cognitive and institutional perspectives of eco-efficiency 2 Wuppertal Papers are scientific working papers of a preliminary character aimed at promoting scientific discourse. Comments and contributions to the discussion are expressly desired by the authors. As a report from a research process not yet concluded, the contents do not necessarily reflect the opinions of the Wuppertal Institute. Sl...

Design of products permits to yield goods and services to produce satisfaction on customers, which is measured as value. However, it is at this stage in which most of the environmental impact, from a lifecycle perspective, is added to the product. Eco-design aims at increasing value of products while reducing the burdens on the environment by means conscious design towards efficient use of reso...

Since the eco-efficiencies of all industrial processes/plants have become more and more important, engineers need to find a way to integrate control loop configuration and measurements of eco-efficiency. A new measure of ecoefficiency for control loop configuration was developed, the exergy efficiency factor. The exergy efficiency factor is based on the thermodynamic concept of exergy which can...

Deamination of cytosines results in accumulation of uracil residues in DNA, which unless repaired lead to GC-->AT transition mutations. Uracil DNA glyco-sylase excises uracil residues from DNA and initiates the base excision repair pathway to safeguard the genomic integrity. In this study, we have investigated the effect of single-stranded DNA binding proteins (SSBs) from Escherichia coli (Eco ...

In this paper, we will establish an Eco-efficiency evaluation index system which is based on the characteristics of the steel industry. Using the principal component analysis to eliminate the impact of the evaluation, reduce the workload of the selection of indicators, and establish the DEA model of the iron and steel industry Eco-efficiency. Finally, we test and verify the effectiveness of thi...

The level of sustainable development can be measured by eco-efficiency, which is a combination of economic and ecological performance. Utilizing the weighted sum of the improved proportions of the indicators as the objective function, this paper develops a proportional slacks-based measure model to assess eco-efficiency, in which the conventional inputs, and desirable and undesirable outputs ar...

* 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...

Purpose: Sustainability and the search for solutions that are both efficient and ecologically sound (eco-efficient) have become topics of great interest. However, companies seeking to develop supply chain solutions that are eco-efficient are often hampered by their ability to control the wider supply chain and they may need to draw upon external support from logistics service providers (LSPs). ...
