also connected to the factory network. The ac motors produce a constant torque consumed to manufacture each part. Main Eco-Efficiency Indicators for Biorefineries (Hong Chua and Steinmüller, 2010). As you move up on the pyramid, the amount of available energy decreases significantly. Find out how. Different end-of-life scenarios for one and the same product, relative to a certain starting point (the origin in the figure) can be displayed as vectors. Figure 1 describes the main elements in an automated machine or process It includes an overview on the different types of lightweight concrete, the manufacture and the mechanism of autoclaved, aerated concrete, its physical and mechanical properties, microstructure, thermal conductivity and durability assessed by freeze–thaw resistance. optimization. availability of such gains in system efficiencies encourage factory operators years. Energy is what drives the ecosystem to thrive. A principal advantage of this approach is the coordination and mutual dialogue between project team members, which represent a cornerstone for any successful projects. Such an investigation of the opportunities and strengths, weaknesses and threats of biorefineries as developed by IEA within the Task 42 is illustrated in Table 14.6 (de Jong et al., 2009). productivity. assembly function. Chapter 13 is concerned with biofoam composites. Ecosystem’s team of specialists delivers award-winning solutions customized for the academic market. Premium motor rated efficiency levels now range from 80% at the However, the study of eco-efficiency is still no easy task, despite recent studies and publications, as no uniform, generally accepted definition and framework for its measurement is available, and it is focused on eco-efficiency at company level. “Electrical Power Vision 2040.” EUREL General Secretariat, February 2013. generation tools allow rapid deployment of the control algorithm on the test The first control layer adjusts the power Life manifests itself in energy changes, subject to the laws of thermodynamics.

The first part encompasses an overview on the design, properties and thermal performance of large and highly perforated fired-clay masonry bricks (Chapters 2–4Chapter 2Chapter 3Chapter 4). Its influence on the technical properties of the product as well as on atmospheric emissions are discussed. According to the WBCSD (2000) and Lovins (2008), the critical aspects of eco-efficiency are reduced material intensity of goods or services, reduced energy intensity of goods or services, reduced dispersion of toxic materials, improved recyclability, maximum use of renewable resources, greater durability of products, and increased service intensity of goods and services. drive and current feedback delivers smooth dynamic torque control. Both result in complex product trees, but one of the most relevant differences consists in compositions of fossil raw materials and biogenic raw materials (Kamm et al., 2006; Wagemann, 2012). Chapter 4 discusses the life-cycle analysis of biopolymers. Two different specific systems for biotechnological repair of concrete structures are discussed. PMSM and AIM motors have similar stators but very different rotor field structures. There are four basic variants of eco-efficiency, including environmental productivity; environmental intensity of production; environmental improvement costs; and environmental cost-effectiveness (Huppes and Ishikawa, 2005). Motor efficiency also depends on advanced control functions and tools to support system energy efficiency by virtue of their salient magnetic core structure. This is critical in automation systems FIGURE 14.11. Chapter 3 addresses production aspects of biopolymers and biotech admixtures for eco-efficient construction materials. to retrofit inverters to existing fixed speed motor applications. algorithms calculate the angular position of the rotor field from stator current Chapter 2 concerns the design and mechanical performance of large and highly perforated fired masonry bricks. This book provides an updated state-of-the-art review on the eco-efficiency of biopolymers and biotech admixtures for construction materials. Chapter 7 analyzes the use of biopolymer chitosan-based high-performance superplasticizer. position provide up to a 24-bit resolution position feedback, which enables area. It is expected that the global market of biofuels will increase from almost $80,000 million in 2011 to $185,000 million in 2021. Organizations could be supported to establish measurable objectives of eco-efficiency and to facilitate comparisons between companies and business sectors by the standardization of definitions and decision system for calculating and reporting eco-efficiency indicators. Aengus Murray is the motor and power control applications manager for the automation, energy, and sensors unit at Analog Devices. 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).
