Abstract:

According to current estimates, industrial effluent discharge has contaminated around one-third of INDIA’s water, solid waste, and other hazardous waste.The bulk of these defaulting industries are petrochemicals, sugar mills, distilleries, leather processing industries, paper mills, agrochemical and pesticide manufacturing sectors, and pharmaceutical businesses.For these industries, surface water is the major waste disposal method.Untreated or ostensibly treated effluents have raised the quantity of surface water pollution by up to 20 times the acceptable limit in 22 seriously polluted locations throughout the world. Almost all water bodies in INDIAwas found to be contaminated by industrial activity. Although the strict guidelines of the Central Pollution Control Board(CPCB) apply to all industries in India, the current state of the environment is far from ideal.

Abstract:

To ensure competitiveness in world markets in the context of deepening globalization processes, Ukraine needs to adjust its own raw material base, which will qualitatively change the structure of Ukrainian exports from raw materials to goods with a high share of value added. The purpose of the article is to assess the development capacity of chemical, textile, agro-processing, and woodworking industries of Ukraine on the basis of import substitution and export orientation and substantiation of organizational and economic forms of its practical implementation. The author’s interpretation of the term “capacity of industrial system development” is offered. Based on the results of the technological profile analysis, the level of capacity utilization and performance indicators of the largest chemical enterprises of Ukraine, and strategic guidelines for the development of promising chemical industries are substantiated and organizational and economic forms of realizing their capacity are suggested, in particular in the Western region. Proposals for ensuring competitive conditions for participants in the domestic market of light industry products are provided, the need for simplified regulatory procedures and investment incentives to ensure the development of domestic light industry enterprises is substantiated. An organizational mechanism for restoring the raw material base of textile and other industries is developed. The regions of Ukraine are grouped according to the capacity of timber harvesting and industrial processing. The perspective directions of development of the woodworking industry in the Western region (in the context of productions) are defined and the basic strategies of their realization focused on the internal and external markets of production are outlined. The organizational forms of realization of the development capacity of agro-processing productions in Ukraine and mechanisms of their institutional support are offered.

Abstract:

Indonesia is rich in diversity of agroindustrial products. Yet the tropical climate causes agroindustrial products being easily damaged. Techniques for food preservation have been widely known such as drying, cooling or freezing, canning, chemical use and others. To complement these techniques, a promising unconservative technique using ionizing radiation can be safely used to preserve food, without leaving residual radiation or hazardous chemical residues. Unfortunately in Indonesia, the irradiation technique was still not common since few industries have used this technique. Compared to the neighbouring countries, only Indonesia as a big country had no interest in developing irradiator technology. To introduce this technique to the public, especially investors, BATAN in 2017 built a pilot project named as Iradiator Gamma Merah Putih (IGMP). It was designed with maximum activity up to 2 MCi using Cobalt-60 as radioactive sources and can serve from low to high dose. By the time, the number of agroindustrial customers, as well as their quantity to be processed, are increasing. The irradiation technique becomes an appropriate technology for Indonesian agroindustries. It is then necessary to build gamma irradiation facilities in areas that have large agricultural yields. This way can minimalize crop losses and increase the quality of the agricultural products.

AbstractThe objective of the research presented in this Research Communication was to access the environmental impact of the Latvian dairy industries. Site visits and interviews at Latvian dairy processing companies were done in order to collect site-specific data. This includes the turnover of the dairy industries, production, quality of water in various industrial processes, the flow and capacity of the sewage including their characteristic, existing practices and measures for wastewater management. The results showed that dairy industries in Latvia generated in total approximately 2263 × 103 m3 wastewater in the year 2019. The Latvian dairy effluents were characterized with high chemical oxygen demand (COD), biological oxygen demand (BOD) and total solids (TS). Few dairy plants had pre-treatment facilities for removal of contaminants, and many lacked onsite treatment technologies. Most facilities discharged dairy wastewater to municipal wastewater treatment plants. The current study gives insight into the Latvian dairy industries, their effluent management and pollution at Gulf of Riga due to wastewater discharge.

Abstract:

Raw wool fibers contain fat, suint, plant material and minerals. It is necessary to remove these from wool by scouring with a combination of detergents, wetting agents and emulsifiers before further processing. Dyeing and finishing of wool fibers is necessary for their application in apparel and also in interior, automotive, smart and technical textiles. Some of the detergents and auxiliaries used in scouring are eco-toxic and some of them are endocrine disruptors. In many countries, wool scouring and dyeing effluents cannot be discharged to watercourses without further treatment by removing color and toxic components. Wool fibers can be given chemical treatments to make them stain-resistant, flame retardant, shrink-resistant, photo-stable and resistant to insect attack. Some of the chemicals under current practice to achieve these functionalities in wool are not eco-friendly and their discharge to water course is limited to the consent limit set by environment agencies. Environmental impact assessment of raw wool production is well studied but to our knowledge no comprehensive study has been carried out around the environmental impact of chemical processing of wool. Like those of other fiber types, the wool textile industries are under intense consumer as well as stakeholder scrutiny. Accreditation schemes now exist to provide reassurance to modern consumers, who want to see that not only are the marketed products safe but also that they are processed sustainably under ethically and environmentally acceptable conditions. Several alternatives to improve the environmental credentials of various chemical processes used for wool will be discussed.

Abstract:

This article addresses a number of challenges related to the complexity of industry research. The points of view in solving these problems were studied, and methodological bases for the development of the industrial sector were developed. It is proposed to create in the lower reaches of the Amu Darya large centers of the oil and gas chemical industry, mining industry with non-ferrous metallurgy, industrial bases for the agro-drainage cycle of production, light and processing industries. The first priority should be the formation of the foundations of the market environment in industries. This process is currently taking place in two directions: the creation of new private, joint-stock and other forms of enterprises, as well as through the modernization of industries, the second priority area of economic reforms in industry should be the creation of enterprises that are technologically advanced and have the ability to produce innovative products; the third priority area is the development of infrastructure industries that produce life support products for the population and the service sector, as well as the creation of quickly recouped industrial enterprises that provide deep processing of agricultural raw materials and mineral resources.

Abstract:

Lignocellulosic biomass feedstocks are promising alternatives to fossil fuels for meeting raw material needs of processing industries and helping transit from a linear to a circular economy and thereby meet the global sustainability criteria. The sugar platform route in the biochemical conversion process is one of the promising and extensively studied methods, which consists of four major conversion steps: pretreatment, hydrolysis, fermentation, and product purification. Each of these conversion steps has multiple challenges. Among them, the challenges associated with the pretreatment are the most significant for the overall process because this is the most expensive step in the sugar platform route and it significantly affects the efficiency of all subsequent steps on the sustainable valorization of each biomass component. However, the development of a universal pretreatment method to cater to all types of feedstock is nearly impossible due to the substantial variations in compositions and structures of biopolymers among these feedstocks. In this review, we have discussed some promising pretreatment methods, their processing and chemicals requirements, and the effect of biomass composition on deconstruction efficiencies. In addition, the global biomass resources availability and process intensification ideas for the lignocellulosic-based chemical industry have been discussed from a circularity and sustainability standpoint.

Abstract:

Citrus is the largest grown fruit crop on the globe with an annual production of ~110–124 million tons. Approximately, 45–55% of the whole fruit post-processing is generally discarded as waste by the food processing industries. The waste is a huge problem to the environment in terms of land and water pollution along with displeasure from aesthetic viewpoint and spread of diseases owing to its huge content of fermentable sugars. The waste can be utilized as a raw material feedstock for producing a number of valuable chemicals and products, such as bioethanol, biogas, bio-oil, organic acids, enzymes, and so on. The production of these chemicals from waste biomass gives an inexpensive alternative to the harsh chemicals used during industrial synthesis processes as well as the possibility of controlling pollution from the waste discarded to the environment. The derived chemicals can be further utilized in the production of industrially important chemicals, as solvents and building blocks of newer chemicals. Furthermore, organic acids, pectin, enzymes, prebiotics, etc., derived from citrus wastes have an edge over their synthetic counterparts in practical applications in the food processing and pharmaceutical industries.

Abstract:

Austenitic stainless steels with their very good corrosion resistance are used in industrial applications nuclear and petrochemical industries, pulp and paper chemical, food and chemical processing, biomedical industries and others. But poor tribological and mechanical properties of austenitic stainless steels limit their applications in engineering fields. AISI 316L steel was subjected to transient treatment using high intensity pulsed plasma beams HIPPB. The plasma pulses contained both ions/atoms of electrodes material: Ce, La or (Ce+La) and those of working gas. The pulse energy densities (3.0 J/cm2) were sufficient to melt the near surface layer of steel and introduce REE to the melted material. Heating and cooling processes were of non-equilibrium type.

Abstract:

This paper presents the development of environmental monitoring mechanism based on Arduino Sensor Technology for Industrial Internet of Things (Industrial IoT) Critical Infrastructure (CI) Protection in an Access Control role. Access control of hazardous substances is one of the most vulnerable aspects of Industrial IoT CI. The idea behind this study is to harden environmental security through live ecological monitoring of Temperature, Humidity and emitted hazardous substances or gases due to Industrial activities and processes in Smart CI places such as Nuclear Processing Plant, Thermal Generation Power Industries, Fossil Processing Plant, Military Chemical warfare plant, food processing factory, Agriculture Chemical Manufacturing Plant and many other CI industries. Live monitoring is one of the most important security requirements for any cyber-Access Control Mechanism. The literature revealed that similar systems were developed and implemented in different organizations and with different System Requirements and specifications. However, most CI industries have not automated environmental monitoring requirements and integrated the requirement into a broad institution security continuum. The consequence of neglecting environmental security is climate change. Furthermore, Toxic gas pollution affects millions of people around the world and contributes to about 5.4 percent of deaths worldwide. Pollution kills more people than the combination of malaria, AIDS, and tuberculosis hence the development of security mechanisms to monitor pollutants in the atmosphere. The main objective of this study was to develop a computer-based application for monitoring environmental hazardous substances such as extreme temperature, humidity, carbon dioxide (CO2), carbon monoxide (CO), and Smoke in the atmosphere surrounding Industrial IoT CI Industries. The system development approach employed was the Arduino engineering process model. To achieve this objective, cheaper ecological sensor Networks that include MQ2 and DHT11 Arduino Sensors are connected to Arduino Uno Microcontroller through a solderless breadboard Arduino component. The backend database was MySQL Relational database management system. The developed prototype application produced a number of results including live monitoring of temperature, humidity, CO2, CO, Smoke, and many others. A system evaluation process was conducted and the result indicated 99.999% accuracy levels. The results, it evidence that the developed prototype application can improve environmental security in Industrial IoT CI institutions.

Abstract:

The review is devoted to the problem of corrosion in the chemical processing of wood. Corrosion processes of technological equipment at enterprises of the pulp and paper, hydrolysis and wood chemical industries are considered. The influence of the main chemical substances involved in the technological process or formed during the chemical processing of wood is discussed. The importance of using alloyed, corrosion-resistant steels of grades 10Kh17N13M2T, 10Kh17N13M3T, 08Kh17N15M3T in the processes of chemical transformation is shown. The information on methods of protection of structural materials from corrosion at enterprises in recent years is presented. The prospects of industrial use of the method of anodic protection, which consists in creating a passivating film on the surface of the protected structure by anodic polarization from an external source of direct current, is noted. The importance of using inhibitors in the composition of technological media is discussed, as one of the most effective ways to combat metal corrosion in aggressive media. It is noted that in addition to the well-known inhibitors of acid corrosion KI-1, PB-5, PKU-3, KhOSP-10, urotropin, KPI-3, I-1-V, BA-6, the use of green chemistry advances is promising, in particular, the use of as anticorrosive agents for waste processing of both wood itself and corrosion inhibitors based on plant extracts.

Abstract:

The main objective of this research was to investigate the waste characteristics and management activities in the Savojbolagh industrial zone, Iran, in order to rank the active industries from environmental perspectives using an innovative index. First, the industrial categories with over 50 employees were identified and classified according to their production process. Then, 54 industries were selected and all industrial processes, the types and quantities of products, per capita industrial waste generation, physical analysis and management activities in terms of minimisation, storage, processing, recycling and disposal were evaluated. The required data were obtained through questioners, interviews and field observations. A scoring system was prepared for evaluation of environmental status of waste management practices. Results indicated that the total industrial waste generation rate was 67,258 kg d-1, in which 4528 belonged to hazardous waste. Furthermore, the per capita waste generation rate was 5.51 kg d-1. Plastic, paper and cardboard and metals constituted the most fractions of wastes, respectively. Food and beverage, metallic and chemical/plastic industries were the biggest waste generators. Metallic industries with total score of 502.5 and non-metalic-mineral industries with the total score of 114 were categorised as the best and worst industries in terms of waste management practices.

Abstract:

Carotenoid is a group of pigments naturally present in vegetal raw materials that have biological properties. These pigments have been used mainly in food, pharmaceutical, and cosmetic industries. Currently, the industrial production is executed through chemical synthesis, but natural alternatives of carotenoid production/attainment are in development. The carotenoid extraction occurs generally with vegetal oil and organic solvents, but supercritical technology is an alternative technique to the recovery of these compounds, presenting many advantages when compared to conventional process. Brazil has an ample diversity of vegetal sources inadequately investigated and, then, a major development of optimization and validation of carotenoid production/attainment methods is necessary, so that the benefits of these pigments can be delivered to the consumer.

Abstract:

Present analysis elucidates the steady free convective flow of nanofluid over a stretching sheet embedded in a porous medium. Mass transfer analysis with chemical reaction acts a great role in this study. The consideration of viscous dissipation makes the heat transfer analysis more interesting. The governing equations are remodelled as a system of ordinary differential equation adopting similarity transformation and treated numerically by 4th order Runge-Kutta method along with Shooting technique. The present results are compared with the earlier results which gives a good agreement. Some important findings are; porosity acts as aiding force whereas magnetic parameter as resistive force for fluid velocity, larger values of chemical reaction parameter result lower velocity and concentration. The study is relevant in polymer processing, food processing industries and chemical industries.

Abstract:

Even with the high costs of environmental exposure controls, as well as the chance of control failures, options for industries wanting to implement sustainability through frameworks such as green chemistry are not yet cost-effective. We foresee a “green” industrial revolution through the use of transformative technologies that provide cost-effective and sustainable products which could lead to new business opportunities. Through example, we promote the use of natural and abundant biopolymers such as chitin, combined with the solvating power of ionic liquids (ILs), as a transformative technology to develop industries that are overall better and more cost-effective than current practices. The use of shellfish waste as a source of chitin for a variety of applications, including high-value medical applications, represents a total byproduct utilization concept with realistic implications in crustacean processing industries.

Abstract:

Various industries throughout the world require Standard methods for trade of products and referee analysis. Over the past 20-30 years, a number of wet-chemical Standard methods have been developed and are in use. Due to the large number of elements required for analysis in most products, XRF methods have become attractive as techniques to handle many elements simultaneously with a simple single sample preparation. Despite XRF being in daily use in many industries as an ‘in-house’ method, there are relatively few National or International Standard XRF methods.

Abstract:

The article offers a solution to the problem of legal regulation of industrial waste concept and its separation from the general concept of waste and industrial waste management due to delegated competences on national, regional, and local levels of the current administrative-territorial structure of Ukraine. The main sources of generation/accumulation of large industrial waste volumes are outlined. The article reveals that they include the mining and career development enterprises in the Donetsk-Dnipro area and Lviv-Volyn coal basin, as well as processing industry enterprises, and to a lesser extent, energy, gas, steam, conditioned air, and water supply and sewerage enterprises. In sectoral breakdown, the enterprises are from mining, mining-chemical industry, ferrous and non-ferrous metallurgy, chemical, petrochemical, and allied industries, machinery and metal processing, forestry and wood processing, food and light industries, and energy. Based on the results of the research, the ranges of areas of industrial waste accumulation in organized storages/landfills and the territory of enterprises are outlined, divided into classification groups, and mapped. The article reveals that the shares of industrial waste accumulation by economic entities in mining and career development within the Donetsk coal basin and Dnipro brown coal basins and extraction of manganese and iron ores in their total volumes in Ukraine are the highest. The share in Poltavska oblast amounts to 99.16 %, Kirovohradska – 97.04 %, Dnipropetrovska – 90.16, and Donetska – 62.23 %. The article of the regional operator of industrial waste management system selected by competition regardless of ownership form is substantiated. Currently, the regional strategies of responsible natural resources management by introduction of innovative environmental technologies in production and minimization of the industrial waste generation and environmental threats risk reduction are the top priority.

Full text

Abstract:

Peppers are grown all around the world, usually for fresh consumption, as well as for the industrial production of different products. Pepper (Capsicum annuum L.) seeds are mostly considered a by-product. Recent investigations have shown that pepper seeds have the potential to be a valuable source of edible oil and fiber-rich flour and protein after processing. Pepper seed oil is a high-quality edible oil according to quality analysis (nutritional, chemical, sensory and antioxidant characteristics) and is suitable as an ingredient for use in the food and nonfood industries (pharmaceutical, chemical, cosmetic industries). The literature review presented in this paper revealed the high quality of two pepper seed by-products (pepper seed oil and pepper seed flour (Capsicum annuum L.)), which could guide the food industry toward new product development based on the circular bioeconomy.

Abstract:

Nowadays, there is a requirement for industries to eliminate carbon from their energy mix and substitute it with greener options. This calls for investment in efforts to facilitate the scaling up of technical advancements. Because of the huge amount of waste, a life cycle strategy has been used by industries, especially the food industry, to lessen the environmental impact of their products. One of the sectors that burdens the environment with a significant amount of waste is the potato processing industrial sector. The current study focuses on the valorisation of all the potato processing waste streams (potato peels, potato tubers and slices, starch and low-quality chips) towards bioethanol production at a pilot level. After their physico-chemical characterisations, several experimental trials were performed in order to determine the optimum pretreatment and hydrolysis conditions for each waste stream. Acid hydrolysis, alkaline hydrolysis and hydrothermal pretreatment were examined when no pretreatment resulted in low ethanol yields (below 60%). The optimum results that were obtained were applied in a pilot plant of 200L to examine the upscaling factor. It was verified that upscaling by 1000 times generates comparable and, in some cases, greater results. From the integration of the results and the mass balances of a typical potato processing company, a full-scale implementation plan was also set up, where it was calculated that around 2 m3 bioethanol per week could be produced.

Abstract:

The article is devoted to the study of the role of the professional competence which is to be mastered by the specialists of food production and processing industries under modern socio-economic conditions as well as to identify promising ways to increase the efficiency of the process of competence development by means of distance learning. The relevance of the study related to professional competence of the specialists in the sphere of food production and processing industries is explained by the fact that the production of quality food that does not pose a threat to human health and life (to health and life of future generations either) and does not cause negative consequences for the environment depends more on responsible and professional actions of personnel in the process of technological production. Some approaches to the definition of professional competence have been analysed. The key components of the professional competence of the specialists in the sphere of food production and processing industries have been identified. The phenomenon of social responsibility as a specific professional competence of the specialists in the sphere of food production and processing industries is highlighted. The characteristics of the competence-based approach to the training of the future specialists in the sphere of food production and processing industries are given. The principles facilitating the development of innovative professional competence of a specialist in the sphere of food production and processing industries in a modern educational institution have been investigated. The phenomenon of distance learning and its main advantages in the educational process have been described. The positive influence of distance learning tools on the formation of professional competence which is to be mastered by specialists in chemical and processing industries has been proved. Some recommendations for improving the efficiency of the process aimed at developing the competence under study in terms of distance learning have been given.

Abstract:

The elevated increase of CO2 emissions related to activities of the extractive industry is becoming a challenging issue gradually affecting climate change and global warming. In this frame, the effective utilisation of CO2 through the techniques of Carbon Capture and Storage (CCS) as well as Carbon Capture and Utilisation (CCU) can alleviate the greenhouse effect. Converting CO2 into a value-added chemical or liquid fuel (e.g., methanol, hydrocarbons, propylene, dimethyl ether, ethylene, etc.) is a promising approach in this regard. Methanol (MeOH) synthesis offers a key feedstock for industries, being both an industrial commodity for several chemical products and an efficient transportation fuel. This article presents a review of the CCS and CCU technologies for the production of MeOH in extractive industries. The CCS technologies investigated in this framework are the amine-based absorption and the WGS-enhanced CCS. The CCU technologies are CO2 hydrogenation and enhanced CO2 transformation by the Fischer-Tropsch reaction. Incorporating these systems for the processing of the flue-gases of the extractive industries significantly reduces the CO2 emissions, while creating new revenues by the production of valuable MeOH.

Abstract:

The strong performance of Singapore's chemical industry in recent years has increased public awareness about the importance of this obscure sector in the Singapore economy. In the public rhetoric, much of this robust growth is attributed to the industrial policies implemented by the Singapore government. However, the ultimate decision to built a multibillion dollar chemical-processing plant in resource-scarce Singapore still depends very much on the global strategies of transnational chemical firms (CTNCs). The authors propose a firm-level perspective to aid in understanding the development of Singapore's chemical industry. They argue that the global strategies of CTNCs have a vital role to play in promoting growth within the Singapore chemical industry cluster. Conceived under the 1991 Strategic Economic Plan, the idea of clustering represents a radically different approach to the development of the petroleum-refining, petrochemicals, specialty chemicals, and pharmaceutical industries where previously each was deemed a separate activity. Based on field research into over forty subsidiaries and local suppliers of CTNCs in Singapore, the authors highlight the importance of two major contextual influences on the global strategies of CTNCs: rising global competition and the huge market potential offered by developing countries. Given these circumstances, CTNCs have relied on their established capabilities to formulate spatial strategies for increasing global competitiveness. In Singapore, subsidiaries of CTNCs have tapped into cluster-based advantages to enhance their capabilities, thereby contributing to the further growth of Singapore's chemical industry cluster.

Abstract:

The article provides an overview of the main existing methods for recycling rare earth metals from various types of waste. It was noted that the demand for rare-earth metals is increasing annually due to the growth of advanced technologies, mainly in the sectors of electronics, power engineering and photonics. It has been established that in countries producing final products of high processing, the chemical-technological processes of processing goods that have worked out their life cycle, and, first of all, fluorescent lamps, NdFeB magnets from electronic devices, and nickel-metal hydride (NiMeH) batteries containing rare earths are most quickly created. The most profitable and recycling option is the reuse of products containing rare-earth metals, however, such technologies are applicable for a narrow range of waste. Another important area of REM recycling is the processing of industrial waste. For countries with developed mining and chemical industries, mining processing technologies are attractive. It is shown that for Russia, more appropriate are schemes for the disposal of industrial waste, primarily waste from the production of apatite concentrate. The main problems of the development of REM recycling are identified: low content and dispersion of rare earths in waste; the presence of impurities that impede the extraction of valuable components and the toxicity of the used recycling schemes.

Abstract:

Thermoplastic polymers are extensively utilized in electronics, aerospace, automobile and additive manufacturing industries due to low cost, low temperature processing and reusability. Thermoplastics of different grades and chemical structures arereadily available in the market They can be reusedand reshaped, and also can be manufactured with less weight proportion as compared to the metals and ceramics by providing same strength of material. As a result, the plastics products in the market are getting popular day by day with high demand of customized products due to inception of additive manufacturing technologies. In any case, the issue of recycling these materials is challenge due to enormous energy requirements and varying chemical composition of different polymers. There are both mechanical and financial issues that restrict the advancements in this field. The recycling process of polymers can be done by the four different ways such as primary recycling process, secondary recycling process, tertiary recycling process and quaternary recycling process which can be discussed in this systematic review with practical examples. The modifications and implementation of these polymer waste recycling techniques could help to reduce wastage and save material cost which would directly affect the economy of contemporary industries.

<div><p><em>Robots have become a key technology in various fields. Robotic arms are mostly remote controlled by buttons or panels and sometimes in batch process they are autonomous. The usage of panel boards or control sticks includes a lot of hardwiring and subject to malfunction. It also induces some stress on the operators. Hence major chemical industries like cosmetic manufacturing, paint manufacturing and Biosynthesis laboratory etc., which deals with hazardous environment due to the chemicals and other bio substances, involve humans for the processing. The aim is to reduce the bulk of wiring in the robotic arms and reduce the effort and number of operators in controlling the robotic arm operations. To implement gestures into the process this would be a major breakthrough. This can also be used as pick & place robot, a cleaning robot in chemical industries where a human does not need to directly involved in the process of cleaning the chemicals and also for coating underground tanks.</em></p></div>
