Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods

With crude oil reserves dwindling, the hunt for a sustainable alternative feedstock for fuels and materials for our society continues to expand. The biorefinery concept has enjoyed both a surge in popularity and also vocal opposition to the idea of diverting food-grade land and crops for this purpose. The idea of using the inevitable wastes arising from biomass processing, particularly farming and food production, is, therefore, gaining more attention as the feedstock for the biorefinery. For the three main components of biomass—carbohydrates, lipids, and proteins—there are long-established processes for using some of these by-products. However, the recent advances in chemical technologies are expanding both the feedstocks available for processing and the products that be obtained. Herein, this review presents some of the more recent developments in processing these molecules for green materials, as well as case studies that bring these technologies and materials together into final products for applied usage

Application of Green Building Technologies in Urals Region

A tendency to build high-rise buildings is common for all developing Russian cities. Sustainability and energy efficiency of such buildings are issues of foremost importance besides the strength and reliability of building structures. Nowadays, both of these terms are united in the concept of "green building". The green building concept includes design, construction, and service of buildings aimed at creating comfortable microclimate, increasing energy efficiency, and reducing the environmental impact. In this work the analysis of distinctive features of designing green buildings in Ural region is given on the example of high-rise buildings constructed in Ekaterinburg. The influence of green building technologies on architectural, planning, and design solutions and selection of construction materials is explored as well as aspects of aerodynamics inside and outside the building. The influence of air flows on air permeability of building structures is assessed. The article also describes innovative solutions for creating required microclimate inside the building. © Published under licence by IOP Publishing Ltd

Computer simulation-based analysis of wind load effect on structural capacity of skywalk between Hyatt Regency hotel and multipurpose building complex Iset Tower in Ekaterinburg

This article contains a computer - aided analysis of bearing capacity under wind load for a standard attachment fixture which one is most frequently used for mounting transparent structures. The analysis results of peak positive and negative wind loads acting on the enveloping structure are presented. The stress-strain state of the skywalk facade fixture unit in the elastic strain stage is analyzed. Maximal values of force influence on the plastic deformation of the fixture unit components arise. They are determined on the basis of a nonlinear analysis. The object of the research is a skywalk between the Hyatt Regency hotel building and the Iset Tower high-rise building in Ekaterinburg that is being designed currently. Simulation models and computational experiments were made in ANSYS CFX software complex. © Published under licence by IOP Publishing Ltd.The work was supported by Act 211 Government of the Russian Federation, contract № 02.A03.21.0006
