Abstract:
Designing modern waste recycling systems is an urgent problem. The experience of attracting masters from two leading Russian universities in organizing interaction and cooperation in the development and implementation of waste sorting complexes is considered. Faculties of Russian Academy of National Economy and Public Administration and Moscow Institute of Physics and Technology held a project session for developing and launching innovative technological projects on the market called "Techno marketing". The developed methodological base made it possible to combine educational and entrepreneurial tasks and ensure the promotion of student technological projects. As a result of the conducted project session, a project on the use of computer vision systems for sorting waste was developed, the competitive differences of the project and its technical and economic indicators were presented. The mechanisms for the implementation of an innovative waste sorting project have been determined. Despite being twice as expensive, the waste sorting machine is able to fully pay off 3 times faster than manual sorting, justifying further investment in the project.

Abstract:
A review of foreign and native publications on the use of man-made raw materials, which is formed during the extraction and processing of rocks, in the silicate materials production was presented. It was shown that, the disposal of large-scale industrial waste from mining and ore processing industrial complexes is promising for solving environmental problems and expanding the raw material base of silicate industries. An increase in the waste consumption degree will contribute to the integrated use of mineral raw materials, as well as a decrease in the volume of their accumulation and an improvement in the environmental situation. A literature review has shown the obvious potential of waste as an alternative raw material for partial or complete replacement of traditional raw materials in various silicate industries. On the example of artificial stone, stone casting, cement, concrete, ceramic bricks and tiles production, the technologies of silicate materials and products were considered, where waste disposal is technologically sound and economically feasible. It was shown that, mineral technogenic raw materials (wastes from mining, mechanical processing and enrichment of rocks) are used as a concrete, artificial stone and other composite binder’s filler, as non-plastic and fluxing components of ceramics bodies, and even as the main raw material in the production of stone casting. On specific examples, it was considered how a reasonable rocks waste use in the silicate materials production can improve the products properties. Requirements were formulated and criteria for the applicability of stone mining and stone processing waste in the silicate materials production were determined, consideration of which will reduce the hazards and risks associated with the possible presence of technologically harmful and potentially hazardous substances in waste. Knowledge of the using peculiarities wastes from the extraction and processing of the different rocks will allow to optimize technological processes when replacing natural raw materials with technogenic materials. Providing scientific and technical information on the advantages of using waste in the ceramic, glass-crystalline, binders and composite materials production will contribute to the development of resource-saving environmentally friendly technologies, natural resources rational use and increase of industrial enterprises responsibility to society and nature.

Abstract:
The article describes the experience of the Compressor holding company in the creation of compressor equipment for various industries. The use of compressors as part of complexes for the processing of organic waste in the framework of solving urgent environmental problems has been demonstrated. The process of compression of synthesis gas to increase the efficiency of the processing process has been investigated. To ensure stable parameters, reliable operation of syngas reciprocating compressors is required in wide ranges of operating parameters. Ensuring the operability of the compressor in wide ranges of parameter variation requires multivariate calculations in order to find the best design parameters of the compressor. A compressor is proposed for the most efficient implementation of the task and its characteristics are calculated.

Abstract:
One serious consequence of the current consumer society is the transformation of the environment into a waste receptacle arising from human activities. Because of the potential toxic effects of chromium solid waste containing this metal there are grounds for serious concern for the tanning and leather processing industry. The application of tannery waste as organic fertilizer has led to extensive contamination by chromium in agricultural areas and may cause the accumulation of this metal in soils and plants. This work evaluated the extraction of Cr+3and Cr+6contained in solid waste from the leather industry through density functional theory (DFT) calculations. The Gibbs free energy calculations reveal that the chelator ethylenediaminetetraacetic acid (EDTA) forms more stable complexes with metal ions of chromium compared with the structures of the complexes [Cr(NTA)(H2O)2] and [Cr-collagen], the latter used to simulate the protein bound chrome leather.

Abstract:
Chitosan has been proposed as a "natural" coagulating agent to solve wastewater problems. The main hindrance in this commercial chitosan application has been its low cost effectiveness. The hypothesis in our research is that chitosan complexes with natural polyanions is more effective than chitosan alone, particularly in recovering low concentration proteins from food processing wastewater. Chitosan (Chi) was reacted with alginate (Alg), pectin (Pec) and carrageenan (Car) ex-situ to obtain chitosan-polyanion complexes (Chi-Pol). Analysis by Fourier Transform Infrared (FTER) spectroscopy confirmed electrostatic interactions as the mechanism for complex formation. Scanning electron microscopy revealed a tight, non-porous structure except for the porous Chi-Car complex. Tests with a bovine serum albumin solution revealed low adsorption rates with slightly higher values for Chi-Car suggesting the need for an improved complexation method. Chi-Pol complexes prepared in-situ at different monomeric weight ratios (MR) were evaluated using pH 6 adjusted Cheddar cheese whey and surimi wastewater (SWW). Complexes used at 30 mg complex/L whey showed higher turbidity reductions than at 10 mg/L. MR had no significant effect on turbidity reduction except for Chi-Alg at 30 mg/L; the value (72 %) at MR = 0.2 was higher than for MR = 0.8. UV-Vis spectroscopy confirmed in-situ complex formation with a preference for the adsorption of specific whey protein fractions. Complexes formed at 0.2 and 0.8 MR were evaluated at two concentrations for the treatment of SWW. Tests at 50 mg/L showed a turbidity reduction of up to 97 % at 24 h with a 81-90 % recovery of SWW proteins. At 150 mg/L, similar efficacy was achieved in only 1 h with turbidity reductions ranging 94-99 % and 78-94 % protein recovery. FTIR analyses confirmed the adsorption of proteins as indicated by similarities in the three amide bands for Chi-Alg recovered solids and untreated SWW. Differential scanning calorimetry (DSC) was employed to study interactions of SWW proteins and Chi-Alg complexes. Untreated and complex bound SWW proteins revealed single exothermic peaks at 23.3 and 38.0°C, respectively. This suggested Chi-Alg and SWW protein interactions increased the thermal stability of SWW proteins. However, further thermal analysis studies are needed to confirm this finding.

Abstract:
Currently, wood waste in the form of a dissected crown on the ground and the root fraction of the tree's biomass in the ground remain in felling areas, becoming potentially dangerous combustible materials in the event of forest fires, as well as obstacles to reforestation activities, and possible foci of infections. Shredding wood waste into wood chips will solve the problem of their disposal by using fuel chips as an additional source of heat energy. In the present work, the influence of design and operational parameters of milling machines with a modernized hydraulic system and equipped with active working bodies on the process of shredding wood waste is established. The annual economic effect from the introduction of the developed complex of wood waste shredding machines and economic indicators from the use of fuel chips are given.

Full text
Abstract:
The last substantive chapter examines a third case study which differs in important ways from the first two. Unlike Baocun and Qiancun, Guiyu town is a well-known, indeed a notorious environmental health hotspot. Pollution is caused by a vast and complex cottage industry processing electronic waste. Chapter 5 explores how such “e-waste work” became closely embedded within the local community, family and social relations, as domestic and work spaces were inextricably blurred. It disaggregates the black box of “e-waste work” to show how it evolved over time, the great diversity that composes the sector, how the government attempted to regulate particular activities within it and why their efforts were not fully effective. It shows that, as in Baocun and Qiancun, the economic benefits and environmental costs of these activities are unevenly distributed. By describing a range of diverse e-waste workers engaged in a spectrum of more or less polluting work, the chapter illustrates how locals fashion counter-discourses of relative harm to excuse their practices and avoid blame. In these circumstances, as in Baocun, toxicity is naturalised and parameters of health are adjusted to normalise and accept widespread pollution-induced ailments.

Abstract:
Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a byproduct of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical precipitation, sedimentation, and other primary processes, whereas secondary sludge is the activated waste biomass resulting from biological treatments. Quite often the sludges are combined together for further treatment and disposal. Sludge from biological treatment operations is sometimes referred to as wastewater biosolids. Of the constituents removed by the treatment, solids and biosolids are by far the largest in volume, and their processing, reuse, and disposal present perhaps the most challenging environmental problem and complex problem in wastewater treatment processes. Therefore, the chapter is devoted to the discussion of the sources, characteristics, quantities, disposal, digestion, and stabilization of sludge so as to present background data and information on these topics that will serve as a basis for the designing of sludge processing, treatment, and disposal facilities.

Abstract:
This book chapter presents the integration of widely available technologies to bridge the gap between mobile devices and their computational rich surrounding environments. Taking as common glue Cloud Storage systems, new interaction between devices becomes more natural. The processing of files can be transparently executed on nearby computers, taking advantage of better hardware and saving mobile devices power. In this chapter, the authors present a novel resource evaluation mechanism, which allows a finer evaluation and more precise comparison of remote resources, leading to fewer wasted resources and better use of those resources. The use of remote resources can be performed by means of processing offloading, executing complete application on remote devices or by relocation of mobile classes. Both methods resort to the presented resource evaluation mechanism. Monolithic applications are transformed (with information from a configuration file) into distributed application, where some components execute on remote devices: nearby computers (to take advantage of existing human-computer interaction devices) or on the cloud (to speed processing). Processing offloading is accomplished by executing on nearby computers applications compatible with the one on the mobile device. This speeds that processing task (better CPU, better interaction devices), reducing the mobile device’s power consumption.

Full text
Abstract:
A novel technology was developed for treatment of evaporator concentrates produced as a result of operation of evaporation devices comprising the main component of special water purification systems of nuclear power plants (NPP). The developed technology includes a hydrothermal (T = 250–300°C and P = 80–120 bar) processing of evaporator concentrates in oxidation medium in order to destruct stable organic complexes of cobalt radionuclides and remove these radionuclides by oxide materials formed during such a processing. The cesium radionuclides contained in evaporator concentrates are removed by a conventional method — through application of one of the developed composite sorbents with ferrocyanides of transition metals used as active agents. Extensive laboratory studies of the processes occurring in evaporator concentrates under hydrothermal conditions were performed. It was shown that hydrothermal oxidation of evaporator concentrates has a number of advantages as compared to traditional oxidation methods (ozonation, photocatalytic, electrochemical and plasma oxidation). A laboratory installation was built for the flow-type hydrothermal oxidation of NPP evaporator concentrates. The obtained experimental results showed good prospects for the developed method application. On the basis of the results obtained, a pilot installation of productivity up to 15 l/hour was developed and built in order to work out the technology of evaporator concentrates hydrothermal treatment. The pilot tests of the hydrothermal technology for evaporator concentrates hydrothermal treatment were performed for 6 months in 2006 at the 1st reactor unit of the Novovoronezhskaya NPP (Voronezh Region, Russia). Optimal technological regimes were determined, and estimations of the economic soundness of the technology were made. The advantages of the presented technology in terms of management of concentrated liquid radioactive wastes (LRW) at nuclear cycle facilities, as compared to other methods applicable for this type of LRW, were demonstrated. Application of the hydrothermal technology in the system of NPP LRW management enables one to reduce substantially the volume of solid radioactive waste sent for final disposal.

Abstract:
Humic substances represent the most extensive and reactive class of natural compounds. A more nature-saving way is to obtain humus substances from solid combustible minerals and waste from their processing. The ability of these compounds to form stable complexes with heavy metals, which increases with their directed chemical modification, has been experimentally confirmed. The effectiveness of the phenol-formaldehyde condensation method for the modification of initial humus substances has been confirmed. The interaction of humic and himatomelanic acids with formaldehyde leads to an increase in sorption activity in comparison with the initial humic acids with respect to heavy metals. This aspect has been studied and confirmed in model experiments with copper ions. Key words: humic substances, brown coal, humic and himatomelanic acids, directed chemical modification, hydroxymethyl (methyl) derivatives, heavy metals, copper ions, complex formation.

Abstract:
A Small-Scale Solution for a Big Energy Problem: Renewable Distributed Energy. Locally generated biomass, industrial and municipal wastes, coal and plastics have a significant part to play in providing a source of reliable and economic energy in the US. The ability to use these materials reliably and cleanly can be addressed with small-scale gasification technology to provide distributed generation. A technology that has improved on the historical success of gasification to provide these elements is TURNW2E™ Gasification. This technology is specifically designed to convert locally available energy resources into a clean fuel gas which is then subsequently used for heat and or power generation. This technology has the ability to operate cleanly and interchangeably using waste materials and /or coal. With the ability to produce power economically from 100 kW to 5 MW it can provide distributed generation at institutions, DOD facilities, and industrial complexes. This creates a reliable and economical energy source for the user, while disposing of wastes in an environmentally sound manner. This replaces landfill use with the energy transformation process of gasification, which provides enormous environmental benefits, including the elimination of carcinogens and reduction of greenhouse gas emissions caused by incineration processes. The use of renewable biomass and wastes provides a sustainable source of electricity that is unrestricted by grid access, providing tremendous potential to reduce US fuel imports. Using this approach, the user can create jobs and power in a sustainable scenario; without sending precious energy dollars overseas, using this process in a distributed manner will help strengthen our nation’s economy, and provide improvements to the quality of life wherever it is installed. By having the ability to use many different feedstocks, the technology can enable the avoidance of landfilling MSW and industrial wastes, including tires; it can use waste wood such as railroad ties, beetle-infested pine, and forestry wastes, farm wastes and natural disaster debris to generate renewable energy for local use or sale to the grid. Materials for processing are varied, and thus, the technology flexibility enables small-scale use in a wide range of installations, a landfill site, transfer station, farm, hospital, manufacturing facility, resort, DOD base, island community, university, and local municipal site. TURNW2E™ Gasification is available at commercial scale and is currently installed at two facilities overseas, with three US facilities planned for ’09. A training and continuing education /R&D facility is underway in the US.

Abstract:
Highly selective removal of Cesium and Strontium is critical for waste treatment and environmental remediation. Cesium-137 is a beta-gamma emitter and Strontium-90 is a beta emitter with respective half-lives of 30 and 29 years. Both elements are present at many nuclear sites. Cesium and Strontium can be found in wastewaters at Washington State’s Hanford Site, as well as in wastestreams of many Magnox reactor sites. Cesium and Strontium are found in the Reactor Coolant System of light water reactors at nuclear power plants. Both elements are also found in spent nuclear fuel and in high-level waste (HLW) at DOE sites. Cesium and Strontium are further major contributors to the activity and the heat load. Therefore, technologies to extract Cesium and Strontium are critical for environmental remediation waste treatment and dose minimization. Radionuclides such as Cesium-137 and Strontium-90 are key drivers of liquid waste classification at light water reactors and within the DOE tank farm complexes. The treatment, storage, and disposal of these wastes represents a major cost for nuclear power plant operators, and comprises one of the most challenging technology-driven projects for the DOE Environmental Management (EM) program. Extraction technologies to remove Cesium and Strontium have been an active field of research. Four notable extraction technologies have been developed so far for HLW: solvent extraction, prussian blue, crystalline silicotitanate (CST) and organic ion-exchangers (e.g., resorcinol formaldehyde and SuperLig). The use of one technology over another depends on the specific application. For example, the waste treatment plant (WTP) at Hanford is planning on using a highly-selective organic ion-exchange resin to remove Cesium and Strontium. Such organic ion-exchangers use molecular recognition to selectively bind to Cesium and Strontium. However, these organic ion-exchangers are synthesized using multi-step organic synthesis. The associated cost to synthesize organic ion-exchangers is prohibitive and seriously limits the scope of applications for organic ion-exchangers. Further issues include resin swelling, potential hydrogen generation and precluding final disposal by vitrification without further issues. An alternative to these issues of organic ion-exchangers is emerging. Inorganic ion-exchangers offer a superior chemical, thermal and radiation stability which is simply not achievable with organic compounds. They can be used to remove both Cesium as well as Strontium with a high level of selectivity under a broad pH range. Inorganic ion-exchangers can operate at acidic pH where protons inhibit ion exchange in alternative technologies such as CST. They can also be used at high pH which is typically found in conditions present in many nuclear waste types. For example, inorganic ion-exchangers have shown significant Strontium uptake from pH 1.9 to 14. In contrast to organic ion-exchangers, inorganic ion-exchangers are not synthesized via complex multi-step organic synthesis. Therefore, inorganic ion-exchangers are substantially more cost-effective when compared to organic ion-exchangers as well as CST. Selective removal of specified isotopes through ion exchange is a common and proven treatment method for liquid waste, yet various aspects of existing technologies leave room for improvement with respect to both cost and effectiveness. We demonstrate a novel class of inorganic ion-exchangers for the selective removal of cesium and strontium (with future work planned for uranium removal), the first of a growing family of patent-pending, potentially elutable, and paramagnetic ion-exchange materials [1]. These highly selective inorganic ion-exchangers display strong chemical, thermal and radiation stability, and can be readily synthesized from low-cost materials, making them a promising alternative to organic ion-exchange resins and crystalline silicotitanate (CST). By nature, these inorganic media lend themselves more readily to volume reduction (VR) by vitrification without the issues faced with organic resins. In fact, with a simple melting of the KMS-1 media at 650–670 deg. C (i.e., well below the volatilization temperature of Cs, Sr, Mn, Fe, Sb, etc.), a VR of 4:1 was achieved. With true pyrolysis at higher temperatures or by vitrification, this VR would be much higher. The introduction of this new family of highly specific ion-exchange agents has potential to both reduce the cost of waste processing, and enable improved waste-classification management in both nuclear power plants (for the separation of Class A from B/C wastes) and DOE tank farms [for the separation of low level waste (LLW) from high level waste (HLW)]. In conclusion, we demonstrate for the first time a novel inorganic ion-exchanger for the selective removal of Cesium and Strontium. These inorganic ion-exchangers are chemical, thermal and radiation stable. These inorganic ion-exchangers can be synthesized in a cost-effective way which makes them significantly more effective than organic ion-exchange resin and CST. Finally, new thermal options are afforded for their final volume reduction, storage and disposal.

Abstract:
Activated carbon can be obtained in a variety of ways. The most promising in terms of resource conservation and economic benefits is the method of producing activated carbon from wood waste. The production of activated carbon by this method is based on the process of pyrolysis of wood waste. As a result of thermochemical processing, charcoal and pyrolysis gas are formed. Then the charcoal must undergo a high-temperature activation process, during which micropores are formed in the coal and it significantly increases its adsorption properties. The hardware design of these processes is a set of complex design and technological solutions. When designing the installation, it is necessary to carry out calculations designed to optimize the equipment and operating parameters of the processes of thermal decomposition and activation of coal, which make it possible to obtain a high-quality product. The paper describes a plant for processing wood waste into activated carbon. The processes occurring in each zone of the installation, as well as the principle of their operation, are considered in detail.

Abstract:
The intensive development of agriculture in the Voronezh Region has led to serious negative changes in the soil condition. There was a decrease in the content of humus and mineral substances. More than 350 thousand hectares of the region’s soils have a low content of humus and, as a result, organic matter (s) available for decomposition. Among the methods of soil restoration, soil improvers are gaining popularity. These are, as a rule, compost, various organic fillers, bio-coal. The latter are considered promising meliorants of natural origin. The processing of waste from the timber industry and sewage sludge into bio-coal is proposed. Its influence on the water permeability of leached chernozem is studied. The positive effect of biochar on the filtration properties of the soil has been established. The filtration rate after applying the biochar increased by 2.5-4 times compared to the control. The maximum water permeability was observed at a biochar concentration of 20 -30% to the soil mass. It is established that the amount of moisture that has passed through the soil depends on the dose of the introduced biochar. The addition of biochar in the amount of 5, 10, 20 and 30% led to a significant increase in the filtration qualities of the soil, compared with the control. The tendency of the ability of biochar to improve the water-physical properties of the soil is revealed.

Abstract:
Abstract Slurries and sludges across the United States Department of Energy (DOE) complex rank among the most rheologically interesting. Their composition is heterogeneous, spanning a very broad range of particle sizes, densities, and interparticle forces. All exhibit shear thinning, some have yield stresses, and many are thixotropic. Despite the variety, these complex fluids are often represented using the historic Bingham fluid model, which fits higher shear rate data to a simple straight line. The intercept provides a yield stress, which has been a key design parameter in construction of large-scale waste processing facilities. However, many radioactive wastes are simply not Bingham fluids, and this representation extrapolates poorly across low to intermediate shear rates that are characteristic of typical processing conditions. Indeed, processing shear rates as high as 200 1/s, which has been a typical minimum shear rate used in fitting the Bingham fluid model, are seldom encountered in nuclear waste processing. Therefore, more realistic rheological models are necessary to accurately predict waste processing performance. Pacific Northwest National Laboratory (PNNL) recently re-evaluated the rheology of reconstituted Hanford REDOX (reduction-oxidation) process sludge waste against a wide variety of rheological models including the Bingham, Cross, Cross with yield stress, Carreau, biviscous, Herschel-Bulkley (which includes a power law dependence), Casson, and Gay models. They found that all of the models provided a closer fit than the Bingham model and that the biviscous model and Cross with yield stress model were convincing. However, reconstituted Hanford REDOX sludge waste is but one type of DOE waste and a direct contrast, and comparison of these three models against undiluted, unmixed tank waste (actual not simulant) has not been performed previously. Therefore, the purpose of this paper is to evaluate the rheology of actual tank waste with these more accurate rheological models. In this paper, we evaluate select rheological data for slurry samples from Hanford’s AZ-101, AZ-102, and SY-101 waste tanks. In each of these cases, we find that Cross’ model with yield stress and the biviscous model significantly outperform the Bingham fluid model. Furthermore, the AZ-101 data also shows that the shear stress peak at startup significantly exceeds the Bingham yield stress, which is commonly observed in the initial moments of rheological measurements on simulants. Remarkably, Cross’ model may empirically accommodate an initial spike in shear stress at modest shear rates. These are important observations because computational and analytical fluid dynamics simulations rely on rheological constitutive models for accurately and conservatively predicting waste processing performance. These findings suggest the need for better rheological modeling of and validation against radioactive waste.

Abstract:
The research provides assessment of current and longer-term consequences of iron ore open pit mining for land resources of adjacent areas. There are applied methods of analysis of fund materials; comparison of topographic sheets and special maps, visual observation, soil testing, laboratory analyses and statistic processing of data obtained. It is revealed that facilities of iron ore mining and concentration waste accumulation (dumps and tailing ponds) are destructive factors for the local lithosphere, dust chemical contamination being the basic one. The steps aimed at reducing negative impacts of technogenic objects of the mining and raw material complex on the environment are under study.

Abstract:
The World Summit on Sustainable Development in Johannesburg in 2002 set the goal of minimising the adverse impacts of chemicals and waste by 2020. This goal has not been achieved yet. Therefore, other approaches are needed to prevent, minimise, or replace harmful substances. One possible approach is this master thesis which deals with the challenges that the textile importer DELTEX is facing with regard to a transparent communication of chemicals used and contained in the product in its supply chain. DELTEX is bound by legal regulations and requirements of its customer and must ensure that there are no harmful substances in the garments. For each order, the customer requires a chemical inventory from DELTEX which contains the chemical substances and formulations used (so-called "order-wise chemical inventory"). Currently, the suppliers are not willing to pass this on to DELTEX. As a result, DELTEX is faced with the problem of having no knowledge of the materials used in the garments and is thus taking a high risk. The structure of this study is based on the transdisciplinary "delta analysis" of the Society for Institutional Analysis at the University of Applied Sciences Darmstadt. This compares the target state with the actual state and derives a delta from the difference. Based on this, suitable design options are to be developed to close the delta. The study defines the target state on the basis of normative requirements and derives three criteria from this, which can be used to measure design options. By means of guideline-based interviews with experts, an online survey and literature research, it examines the current state. The analysis shows that the relevant actors are in an unfavourable incentive and barrier situation. The textile supply chain can be seen as a complex construct in which a whole series of production sites (often in developing and emerging countries where corruption and low environmental standards exist) carry out many processing steps. Chemicals are used at almost all stages of processing, some of which have harmful effects on people and the environment. At the same time, factory workers in the production countries are under enormous price and time pressure and often have insufficient know-how about chemical processes. DELTEX is dependent on its main customer and therefore has little room for price negotiations. To close this delta, the study formulates design options on macro, meso and micro levels and measures them against the developed criteria. None of the measures completely meets all the criteria, which is why a residual delta remains. The study concludes that not one, but rather a combination of several design options at all levels can achieve the target state. For DELTEX, an alliance with other textile importers, membership in the Fair Wear Foundation, strengthening the relationship with its suppliers and cooperation with another customer are recommended. Furthermore, the use of material data tools that support proactive reporting approaches such as a Full Material Declaration is recommended. The study is carried out from the perspective of the textile importer DELTEX. The results can therefore only be applied to the entire textile supply chain to a limited extent.
