Abstract:
Effective water and waste management strategies enable us to decrease water consumption and pollution load of wastewaters. Typical examples of low-waste technologies are lanolin recovery in wool scouring, hydroxide recovery in cotton mercerizing, recovery of synthetic sizes and reuse of dye baths. Wastewaters are treated by a sequence of physical–chemical and biological processes. Traditionally, coagulation/flocculation(c/F) has been favored as the first treatment step followed by biological treatment as the second step. More recently a reverse sequence of treatment has been utilized in several cases with success. Novel technologies have been developed such as catalytic oxidation, decoloration by ozone, adsorption/desorption. Their practical use is, however, still rare. Joint treatment with municipal wastewaters has been favored wherever possible.

Abstract:
The effects of ultrasonication on the precipitation of precipitated calcium carbonate (PCC) based on mineral carbonation are investigated in a CaCl2-NH4Cl-NH3-H2O system. The experimental results show that high ultrasonic power can delay the induction period of the reaction, and that the pH and conductivity change little as the ultrasonic power changes. The structure of PCC changes from mature, large and spherical particles into aggregates composed of a large number of loose crystals, and a larger proportion of vaterite transforms into calcite under an ultrasonic power of 0% to 30%, which leads to the ultrasonic scouring action. When the ultrasonic power is increased to 60% and 90%, the particle size of PCC decreases, and the proportion of vaterite increases as the ultrasonic power increased further as a result of the high saturation during the prolonged induction period induced by ultrasonication and of the high-power ultrasonic waves shattering the agglomerates rather than scouring the crystal surface.

Abstract:
In the EU, sheep bred for dairy and meat purposes are of low quality, their economic value is not even enough to cover shearing costs, and their wool is generally seen as a useless by-product of sheep farming, resulting in large illegal disposal or landfilling. In order to minimize environmental and health-related problems considering elemental compositions of discarded materials such as waste wool, there is a need to recycle and reuse waste materials to develop sustainable innovative technologies and transformation processes to achieve sustainable manufacturing. This study aims to examine the application of waste wool in biocomposite production with the help of a sustainable hydrolysis process without any chemicals and binding material. The impact of superheated water hydrolysis and mixing hydrolyzed wool fibers with kraft pulp on the performance of biocomposite was investigated and characterized using SEM, FTIR, tensile strength, DSC, TGA, and soil burial testing in comparison with 100% kraft pulp biocomposite. The superheated water hydrolysis process increases the hydrophilicity and homogeneity and contributes to increasing the speed of biodegradation. The biocomposite is entirely self-supporting, provides primary nutrients for soil nourishment, and is observed to be completely biodegradable when buried in the soil within 90 days. Among temperatures tested for superheated water hydrolysis of raw wool, 150 °C seems to be the most appropriate for the biocomposite preparation regarding physicochemical properties of wool and suitability for wool mixing with cellulose. The combination of a sustainable hydrolysis process and the use of waste wool in manufacturing an eco-friendly, biodegradable paper/biocomposite will open new potential opportunities for the utilization of waste wool in agricultural and packaging applications and minimize environmental impact.

Abstract:
The environmental situation in Russia is characterized by a high level of anthropogenic impact on the environment, significant environmental consequences of past economic activity. Their disposal and storage costs 8-10 % of the cost of products, so the disposal of such waste is of paramount importance.Due to the involvement of multi-tonnage waste in the production of ceramic materials of mass consumption, which include wall materials, it is possible to radically change the parameters of the raw material base of Russia, which also helps to reduce environmental tensions in the regions. The reduction of reserves of traditional natural raw materials makes us look for new ways to replace it with different types of waste. The experience of advanced foreign countries has shown the technical feasibility of this area and the use of more as a tool to protect the environment from pollution. However, almost all basic building materials can be made from waste or from waste in combination with natural raw materials. On the basis of fusible clay and waste basalt-gabbro-norite charge, which is formed in the production of mineral wool obtained ceramic brick with high physical and mechanical properties, brick grade M150 and above. The absolute advantage of the use of multi-tonnage waste is the unloading of the environmental situation, which contributes to the solution of industrial waste disposal and environmental protection. Innovative proposals for the use of waste from the production of mineral wool in the production of wall materials - ceramic bricks based on fusible clay, the novelty of which is confirmed by patents of the Russian Federation.

Abstract:
Organic polymeric flocculants have been used in water purification for several decades as coagulant aids or floc builders, after the addition of inorganic coagulants like alum, iron salts or lime. The increased use of cationic polyelectrolytes as primary coagulants instead of inorganic salts, which has occurred in recent times, arises from their significant inherent advantages. The main ones are faster processing, a lower content of insoluble solids to handle, whether by sedimentation, filtration, flotation or in biological conversion, and a much smaller sludge volume. Polymers have often been used in chemically assisted sedimentation of sewage solids to enhance the removal of suspended matter. The concept is applicable as well to the primary coagulation of industrial wastewaters where the separation may be based on flotation, as in examples from the leather, steel, wool scouring, cosmetic, detergent, plastics, dyehouse, paper, food processing and brewing industries. A cationic polymer of particular charge density is optimal, and hydrophobically modified polymers have relevance in the case of oil and grease removal. The burden of solids which must be floated is much reduced relative to systems utilising inorganic coagulants, and the dosage of chemicals overall is lower. In some cases the addition of some inorganic coagulant is unavoidable, as in the case of highly coloured effluents; in others, an anionic surfactant is needed to facilitate flotation.

Abstract:
Greasy sheep wool is currently considered a special waste for its high bacterial load, with expensive disposal costs for sheep breeders. For this reason, wool is often burned or buried, with serious consequences for the environment. On the other hand, sheep wool is well regarded as one of the most performative insulating natural fibers due to its thermo-hygrometric and acoustic properties. In the building sector, sheep wool meets the requirements of green building components because it is an eco-friendly material, there is a surplus of it, it is annually renewable, and totally recyclable. If used instead of common insulation materials (e.g., fiberglass, rock wool, polyurethane foam, polystyrene), sheep wool offers significant benefits for sustainability such as a reduction in the production costs for new insulating materials and in environmental pollution. Mechanical and physical properties of sheep wool investigated in previous studies were assessed and discussed with the aim of providing an organized framework of possible applications of wool fibers in building components. This paper highlights in detail aspects that have not yet been investigated enough to detect new potential uses of sheep wool fibers in rural buildings and the reuse of traditional ones.

Abstract:
Wood fiberboards are used extensively, mainly in the fields of furniture production, interior fittings, construction, etc. Mineral stone wool materials are used for heat and sound insulation in the construction industry. This study aimed to produce a new hybrid-based composite material by mixing fibers obtained from wood and mineral stone wool. For this purpose, hybrid fiberboards with 50, 40, 30, and 20% stone wool addition and a fiberboard group consisting of 100% pine and beech fibers (control sample) were produced in a hot press using thermoset-based urea formaldehyde and phenol formaldehyde resins. Statistical comparisons of the results were made for values of density, thickness swelling, and water absorption extents after 24 h immersion, bending strength and modulus of elasticity in bending, tensile strength perpendicular to the board surface (internal bond strength), and time to ignition (TTI) analysis. Additionally, percentage of mass loss (PML), average heat release rate (A-HRR), average effective heat of combustion (A-EHC), and mass loss rate (MLR) were studied. The results showed that as the stone wool content in the produced boards increased, the mechanical properties and thickness swelling decreased. The combustion results showed that the combustion resistance of the boards increased with increasing stone wool ratio.

Abstract:
The problem of the formation and processing of waste in the production of crushing stone for road construction is considered. An integrated approach is proposed, which implies both a reduction in the amount of waste generated and its subsequent processing to obtain products in demand on the market. The technologies based on the use of vibration equipment and allowing to obtain qualified products from crushing screenings are described: cubical crushed aggregates, high-quality fractionated artificial sand and vibro pressed products based on it. The possible options for recycling the dust-like component of the waste with the production of lightweight aggregate for concrete and mineral wool are given. An estimate of the predicted environmental effect of preventing the disposal of waste from the production of crushing stone for road construction, subject to the application of the proposed technologies, is given.

Abstract:
Valorising biomass waste and producing renewable energy or materials is the aim of several conversion technologies. In this work, we consider two residues from different production chains: lignocellulosic residues from agriculture and wool residues from sheep husbandry. These materials are produced in large quantities, and their disposal is often costly and challenging for farmers. For their valorisation, we focus on slow pyrolysis for the former and water hydrolysis for the latter, concisely presenting the main literature related to these two processes. Pyrolysis produces the C-rich biochar, suitable for soil amending. Hydrolysis produces a N-rich fertiliser. We demonstrate how these two processes could be fruitfully integrated, as their products can be flexibly mixed to produce fertilisers. This solution would allow the achievement of balanced and tuneable ratios between C and N and the enhancement of the mechanical properties. We propose scenarios for this combined valorisation and for its coupling with other industries. As a result, biomass waste would be returned to the field, following the principles of circular economy.

Abstract:
Ceramic fibers are characterized by their light weight, high degree of purity, low heat storage, low thermal conductivity, thermal shock resistance and superior corrosion resistance in high-temperature environments. In addition, they can be produced extensively in substitution to all materials used in the coating of almost all heating equipment as well as contributing to the reduction of energy consumption. Such characteristics make them ideal in the coating of distributors, mufflers, heating ovens, among others, as highly demanded by the mining and metallurgical industries, among others. After use in the process of industrial production, generated waste will lose their insulation capacity and thus require safe disposal. The present work focuses specifically on ceramic and glass wools aiming at an evaluation of their recycling prospect of incorporation into cement mortars and concrete. This residues were pulverized and displayed ~30µm average particle size. The scan electronic microscopy (SEM) presented elongated, thin and straight particles, which is very different than flocular structure of cement. The X-rays diffraction revealed amorphous structure for glass wool and crystalline structure for ceramics wool. The chemical analysis showed high concentrations of Al2O3 and silica in both residues, with higher percentage of calcium oxide in glass wool.

Abstract:
It has been estimated that over 50% of whey production world wide constitutes a pollution problem to the environment. A proportion of the work carried out to make use of whey nutrients has not been commercially viable. A simple process has been developed, at the laboratory and pilot plant scales, resulting in a complete recovery of nutrients from whole whey or whey fractions for animal feeding and no further waste or effluent is generated. The economics of the proposed process rely on efficient use of inexpensive ingredients (or waste materials, from other agricultural sources) to overcome the high cost of dewatering and drying. Using this approach a number of products are possible. In the first product bentonite is used to precipitate whey protein which can be processed into a dry protein concentrate for use in intensive animal, poultry or fish production. This product compares favourably with conventional protein supplements such as meat and bone, soybean, or fish meal. The deproteinised whey, (mainly lactose and minerals) arising from this process, is concentrated and mixed with a carrier to produce a second product for ruminants that can compete with hay or grains. Further, whole whey may be used in a similar process. Animal feeding trials with sheep and dairy cattle have demonstrated advantages of the developed whey products over conventional feed supplements for wool growth, live sheep export or milk production.

Abstract:
Recently, many scientists have been struggling to identify natural dyestuff sources from different plants, especially for dyeing of textile materials such as wool and cotton. One of these struggles was carried out in this paper. The aim of this study was made to reveal R. iconiensis (hub.-mor.) M.V.Agab. & Greuter plant used as a source of natural dyes. In this study, both plant’s flowers and stems have been used separately for the dyeing of wool fabrics. These parts of plants were collected in the summer and separately dried, then milled and powdered and then used as a dyeing material in the dyeing of woollen fabrics via five (Fe, Cu, Al, Cr, Sn) different metal salts. All the dyeing processes were carried out for one hour at boiling temperature. Subsequently, CIE L*a*b* and K/S values of dyed wool fabrics were examined for colour strength. Various colour fastness tests, such as rubbing, washing and light fastness of dyed fabrics, have also been made. In the light of the obtained data, it was seen that R. iconiensis plant could be a natural dyestuff for wool materials.

Abstract:
Environmental problems of the textile industry of the Republic of Kazakhstan are mainly related to the disposal and regeneration of industrial waste, wastewater treatment, the creation of a circulating water supply system, dust removal of the air of the working area, etc.The production of yarn from low-grade cotton and production waste is one of the urgent problems of the industry affecting the economic efficiency of the functioning of textile enterprises.The use of spinning production waste and low-grade raw materials in the production of yarn of high linear density using the pneumomechanical spinning method allows to reduce the cost of a unit of production.Yarn produced with the investment of spinning production waste and low-grade raw materials is used in the manufacture of household, a number of technical, raincoat and clothing fabrics, where significant mechanical loads on the fabric are not required, as well as cotton wool and batting for the furniture and shoe industry. The paper considers issues related to the development of technology for the use of spinning production waste in the production of cotton yarn on the example of JSC «Makta».

Abstract:
Abstract To determine the Novotroitsk gold-arsenic deposit dumps influence on the ecological situation, soil samples were taken from 4 wells drilled in the tailing dump territory. The Southern Urals species plant material typical Samples were collected within a 2 m radius from the wells. Wool, muscle tissue, liver, and kidney samples were taken from the European moles caught on the dump. The comparison objects were plants and animal tissues samples from background areas at a distance of > 15 km from the tailing dump. In the samples, the elements’ contents were determined, incl. arsenic and heavy metals by inductively coupled plasma mass spectrometry. Heavy metals increased content in the soil was found, and the average content of arsenic exceeded the maximum permissible concentration in soils by 1256 times. As and Hg large amounts were also found in plant samples. In the mole wool and tissues, the As accumulation was noted 181.3 - 273.9 times higher than the background values, Hg - 9.9 - 70.8 times and somewhat less pronounced - copper, lead and zinc. The research results are recommended to be taken into account when organizing reclamation and reclamation measures, as well as mining waste storage and disposal.

Abstract:
AbstractUnder the alkaline conditions expected in an intermediate-level waste repository, cellulosic material will undergo chemical hydrolysis. This will produce hydrolysis products, some of which can form soluble complexes with some radionuclides. Analyses of samples containing autoclaved tissue and cotton wool incubated in a saturated solution of Ca(OH)2 ( pH > 12) confirmed previous reports that isosaccharinic acid (ISA) is produced from these cellulose polymers at high pH. However, when inoculated with a sediment sample from a hyperalkaline site contaminated with lime-kiln waste, microbial activity was implicated in the enzymatic hydrolysis of cellulose and the subsequent production of acetate. This in turn led to acidification of the microcosms and a marked decrease in ISA production from the abiotic alkali hydrolysis of cellulose. DNA analyses of microbial communities present in the microcosms further support the hypothesis that bacterial activities can have a controlling influence on the formation of organic acids, including ISA, via an interplay between direct and indirect mechanisms. These and previous results imply that microorganisms could have a role in attenuating the mobility of some radionuclides in and around a geological disposal facility, via either the direct biodegradation of ISA or by catalysing cellulose fermentation and therefore preventing the formation of ISA.

Abstract:
Due to the overall improvement of living standards and considering the priority to reduce the energy consumption, the adoption of efficient strategies, mainly in the building area is mandatory. In fact, the construction sector can be considered as one of the key field essential for the sustainability, due to the diversity of components and their life cycles. Reuse strategies may play an essential role in reducing the environmental impact of building processes. Within this framework, the reuse of textile waste to produce insulating materials represents one of the biggest opportunities for the promotion of a circular economy. It contributes significantly to improve the environmental sustainability reusing a waste as new raw matter involved to achieve high energy efficient buildings. This paper provides the results of an experimental campaign performed using wool waste derived from the industrial disposal of fabrics matched with phase change materials (PCMs) used in order to enhance the thermal mass of the final products. Physical and thermal parameters were measured in order to demonstrate the good performances of the textile materials and the essential role played by PCMs in shifting heat waves and reduce surface temperatures. Furthermore, DesignBuilder software was used to assess the energy consumption of a mobile shelter type structure under three different climatic scenarios. A comparison between the experimented materials and other solutions, currently available in the market, highlighted a significant reduction in energy consumption when adopting the materials under test.
