Measuring the eco-efficiency of cement use - ScienceDirect

01/09/2010  In this study, two indicators are proposed which allow measuring the eco-efficiency of cement use, binder intensity and CO 2 intensity. Both indicators have performance, e.g. mechanical strength, as a functional unit, an innovation which might allow the development of an entire family of new indicators. Both indicators were tested using two sets of data from literature, one Brazilian and the ...

01/06/2020  Increases in the eco-efficiency indicator CI were observed with the reduction in cement consumption for the concretes and sand-concretes produced with the ERMA BOFS-C. This trend was observed for all mixtures and represented an interesting finding in this research. The increase in CI indicator is commonly related to increases in the compressive strength, i.e., good binder efficiency is ...

01/10/2016  Under this measurement scale, the final eco-efficiency scores will be blurry and little conclusion and discussion could be made. To make the eco-efficiency scores comparable, a normalization technique could transform the measurement scale of economic indicators into the same range that the environmental indicator is measured in, from 0 to 120.

Eco-Efficiency - an overview ScienceDirect Topics

Eco-efficiency is a management strategy of doing more with less (Glavič et al., 2012). It is based on the concept of creating more goods and services while using fewer resources and creating less waste and pollution (Glavič et al., 2012). Eco-efficiency is a sustainability measure combining environmental and economic performances.

Measuring the eco-efficiency of cement use Semantic Scholar

This paper proposes indicators for measuring cement use efficiency, presents a benchmark based on literature data and discusses potential gains in efficiency. The binder intensity (bi) index measures the amount of binder (kg m−3) necessary to deliver 1 MPa of mechanical strength, and consequently express the efficiency of using binder materials. The CO2 intensity index (ci) allows estimating ...

Eco-efficiency of the world cement industry: A data ...

Chemical reactions and the combustion of dirty fuels, such as coal and petroleum coke (petcoke), that are used in cement production processes generate a significant amount of CO2 emissions. In this paper, we provide an eco-efficiency measure for 21 prototypes of cement industries operating in many countries by applying both a data envelopment analysis (DEA) and a directional distance function ...

[PDF] Measuring and Improving Eco‐Efficiency Using Data ...

The concept of eco-efficiency can be defined with the “product value/environmental influence” ratio. Different models have been proposed to measure eco-efficiency. The main difference among them is the weighting system used to aggregate the environmental results. Data envelopment analysis (DEA) permits this aggregation without requiring a subjective judgment about the weights.

Convergence analysis of eco-efficiency of China’s cement ...

China has become the largest producer and consumer of cement worldwide. In 2011, carbon emissions of China’s cement industries accounted for 60.6% of cement carbon emissions worldwide. In this context, this paper mainly investigates whether eco-efficiency of China’s cement manufacturers has converging tendency or not. First, we evaluated eco-efficiency under directional distance function ...
