Application Of Eco-efficiency Research Articles

Research Methods and Application of Ecological Efficiency

In recent years, the frequent occurrence of extreme weather is a global problem facing all countries. With the excessive consumption of energy and the massive emission of carbon dioxide represented by energy-intensive industries, it has caused serious negative impacts on social and economic development and ecological environment, and it has caused serious negative impacts on social and economic development and ecological environment. Therefore, it is very important to deal with the relationship among economic development, resource input and ecological environment. Eco-efficiency is an important tool for quantitative analysis of the ratio between economic output and resource input, which is closely related to the sustainable development of economy, environment and resources. By reviewing domestic and foreign literature, this paper summarizes the concept, evaluation method and application of ecological efficiency, and concludes that (1) The core concept of ecological efficiency is to obtain more economic benefits with less resource input; (2) Evaluation methods of ecological efficiency: Mainly include data envelopment analysis (DEA), index evaluation method, ecological footprint method, single ratio method and SBM method in the measurement of ecological efficiency, among which DEA model is widely used; (3) The application of eco-efficiency mainly involves enterprises, industries and regions, among which there are few researches on enterprise eco-efficiency.

Eco-Efficiency Assessment Utilizing Recycled Glass Aggregate in Concrete

This paper reviews specific technical and eco-efficiency performance issues in using glass waste as an aggregate in the production of concrete. Eco-efficiency is a relatively modern tool in the pursuit of sustainability. Eco-efficiency is the concept of maximising the benefits from the use of non-renewable resources while minimising the use of non-renewable resources. The paper details a life cycle assessment and eco-efficiency review of a potentially sustainable alternative to traditional concrete, made from ordinary Portland cement. The study follows the ISO framework, which includes goal and scope, a life cycle inventory, life cycle impact assessment, life cycle costing, normalising of data and the creation of an eco-efficiency portfolio. SimaPro life cycle assessment software has been used to further analyse the use of recycled glass aggregate as a replacement for naturally occurring stone aggregate in geopolymer concrete. The study found that the use of geopolymer concrete as a non-cement based alternative concrete was a viable way to reduce emissions with a high global warming potential but faced challenges in other environmental impact areas. There is a need for ongoing research and study on the application of eco-efficiency as a tool in the pursuit of sustainable practices in society.

Application of eco-efficiency in the assessment of raw materials consumed by university restaurants in Brazil: A case study

The production of meals for collectivity is an important activity of the services segment. The concept of eco-efficiency prioritizes more efficient use of materials and energy, thus combining economic and environmental performance. The objective of this study was to propose and apply a procedure to measure and evaluate environmental performance under the eco-efficiency approach for the food production segment. The procedure was applied in five university restaurants of a Brazilian federal public university that served more than 1.5 million meals in 2012. Calculations for assessing eco-efficiency contemplated the inputs used considering the supply of energy in kilocalories and the financial figures for the environmental impacts in which the variables were selected from the water footprint and the amount of waste generated from food used. So far the concept of eco-efficiency was not applied to the food production segment to collectivities. Thus, this study is to contribute and fill that gap.

Application of eco-efficiency in a coal-burning power plant benefitting both the environment and citizens: Design of a ‘city water heating’ system

In this work, the concept ‘city water heating’ is introduced. It consists in bringing a significant amount of residual thermal energy (waste heat) from a power plant to a city by means of heating the potable water supplied to this city. For this purpose (i) a great amount of the city water has to be supplied through a single aqueduct, (ii) the aqueduct has to pass near the power station, and (iii) the water supplied to the city has to be colder than the cooling circuit water in the power plant.The hot water generated in the power plant cooling circuit (which is usually dissipated in the cooling tower) is conducted through a pipe to a place near the aqueduct and, by means of a heat exchanger, part of the cooling water heat is then transferred to the colder potable water supplied to the city. This has the great advantage of using the existing city water network itself to transport the heat to the houses.Based on data from a coal power plant located in Asturias (Northern Spain), two city water heating systems of different sizes are described and analysed. The following advantages were found: (i) energy saving and cost reduction for inhabitants, (ii) reduction in global warming and (iii) CO2 emissions reduction.

A Framework for the Application of Eco-efficiency to the Technology Development Process

The use of technology development process (TDP) models by the enterprises can contribute to the usage control of natural resources of technologies before or after its integration on products, services or processes. Although the choice of a technology can consider the use of some performance metrics to identify their eco-efficiency, the literature about technology development models neglects this element. Based on a qualitative analysis of existing models, this paper proposes a conceptual model for the adoption of eco-efficiency indicators in the TDP by the innovation managers, distributed in three different stages: the initial stage, during the planning of a technology, the intermediate stage, at the technology development, and the final stage, at the technology transfer. Future research, such as prioritizing the indicators and the extent of the present analysis to other sustainability dimensions are suggested for structuring a sustainable model of TDP.

Development of Eco-efficiency as an indicator of sustainable activities of company

Eco-efficiency was prompted by WBCSD (World Business Council for Sustainable Development) as a major concept for company to make in enabling corporate progress towards sustainability. The purpose of this research is to show applicability of eco-efficiency as an evaluation indicator of company's activity to achieve sustainable society. Through investigation of several case studies collected by WBCSD showed that application of Eco-efficiency is still primitive stage. The following issues were pointed out.(1) Most of case studies just calculated limited aspects of environmental loading and various environmental influences were not fully considered.(2) To establish the different quantification method for each users of Eco-efficiency is important. In order to use Eco-efficiency as concept or tool to achieve sustainable society, it showed be more universal. Eco-efficiency with transparent data and calculation method should be used by various stakeholders. Key data to calculate Eco-efficiency depend on the purpose of each stakeholder. The stakeholders are categorized and possible definitions of Eco-efficiency for each stakeholder is discussed in this study.
