Recycling System

Increasing public awareness about low emission and stricter standards has a significant impact on the industry. The use of catalytic converters provides one of the solutions to the problem of lowering the amount of exhaust fumes. As most catalytic converters contain a combination of the three metals Pt, Pd and Rh, the manufacture of catalysts for automobiles is the largest sector of demand for and consumption of PGMs (platinum group metals). In Poland, the recycling system for catalysts is still in the development stage, but there is a significant trend of increase mainly due to EU policy on the circular economy. Due to frequent legal changes, the market is not fully transparent and the price for used catalysts can vary significantly. Therefore, apart from the recycling technology itself, it is important for the company to have a transparent method of testing the catalysts. The aim of this article was to identify the key opportunities and challenges to improving the catalyst recycling system in Poland. The organisational solutions have been analysed to show that an effective system could be implemented by creating a network between suppliers and customers with the use of good laboratory equipment and IT applications. The article defines the key opportunities and challenges such as the need to invest in an innovative laboratory and software for assessment of chemical composition and economic value of waste. A great opportunity for the development of this sector is the high demand for critical raw materials such as PGMs, which can be supported by research and development (R&D) projects.

The small and medium-sized food industry (SMFI) has a great opportunity to meet domestic market demand during the Covid-19 pandemic but there are various obstacles. This paper aims to present the constraints faced by SMFIs, especially concerning raw materials and marketing, in taking advantage of domestic market opportunities, and proposes alternative solutions. The study was conducted on four SMFIs that produce functional food in Malang Regency. Data were collected through in-depth interviews. The results showed that the demand for functional foods such as garlic, ginger, turmeric and fruits increased during the Covid-19 pandemic, which seemed to be related to public awareness about increasing immunity. However, the obstacles faced by SMFIs were the high price of raw materials due to limited supply, and limited marketing because they did not have distribution licenses from BPOM. Information about the process and BPOM’s distribution permit requirements was very limited for SMFI managers, and large capital was needed to fulfill the requirements of Good Manufacturing Practices. Therefore, SMFIs should have long-term cooperation with farmers to ensure the availability of raw materials; build networks and maintain cooperation with customers; and utilize credit for MSMEs in the economic recovery program provided by the government to meet the GMP requirements in BPOM’s distribution permit. The government should conduct intensive outreach to SMFI managers about the process and requirements for distribution permits from BPOM, credit facilities, and other policies related to economic recovery during the Covid-19 pandemic.

This study concerns the technology and the consumer properties formation improvement of cold appetizers from silver carp in the form of a roll. Unlike traditional the developed products consist of fillet of a bighead silver carp on a skin and an original stuff from egg, vegetables and mushrooms. The researchers conducted study using conventional and special methods. They recommended to introduce gelatin in a dry powdered at the stage of roll forming form in a recipe of the developed fish rolls. A man tested fish gelatin as anew consistency regulator of the developed products. The traditional and fish gelatin use allows to increase the yield of fish cold appetizers in the form of a roll by 8.0 %. When adding gelatin, there was an improvement in consistency and sensory perception of the product as a whole. The analysis results of biological value showed that the developed dishes, being an important additional source of protein and essential amino acids such as threonine, lysine, valine, may well improve the ration balance. The fatty acids ratio in fish rolls prepared according to new recipes is close to the ideal fat in the ratio of saturated, monounsaturated and polyunsaturated fatty acids (35:45:20) and is determined mainly by the composition of fatty acids in silver carp fat. The developed production will allow to expand the range of the food industry enterprises by cold fish appetizers of high quality and food value from available fish raw materials.

AbstractThe increase in the world population leads to rising demand and consumption of plastic raw materials; only a small percentage of plastics is recovered and recycled, increasing the quantity of waste released into the environment and losing its economic value. The plastics represent a great opportunity in the circular perspective of their reuse and recycling. Research is moving, on the one hand, to implement sustainable systems for plastic waste management and on the other to find new non-fossil-based plastics such as polyhydroxyalkanoates (PHAs). In this review, we focus our attention on Tenebrio molitor (TM) as a valuable solution for plastic biodegradation and biological recovery of new biopolymers (e.g. PHA) from plastic-producing microorganisms, exploiting its highly diversified gut microbiota. TM’s use for plastic pollution management is controversial. However, TM microbiota is recognised as a source of plastic-degrading microorganisms. TM-based plastic degradation is improved by co-feeding with food loss and waste as a dietary energy source, thus valorising these low-value substrates in a circular economy perspective. TM as a bioreactor is a valid alternative to traditional PHA recovery systems with the advantage of obtaining, in addition to highly pure PHA, protein biomass and rearing waste from which to produce fertilisers, chitin/chitosan, biochar and biodiesel. Finally, we describe the critical aspects of these TM-based approaches, mainly related to TM mass production, eventual food safety problems, possible release of microplastics and lack of dedicated legislation.

Климатические условия на большей части территории Российской Федерации не позволяют выращивать виноград в открытом грунте, поэтому его завозят из южных районов страны. Производство виноградных напитков обычно сосредоточено в местах выращивания винограда, так как доставка готовой продукции в северные регионы сопряжена со значительными финансовыми затратами. В Республике Дагестан выращивают около 30% винограда в масштабах всей страны, а площадь плодоносящих виноградников занимает более 20 тыс. га. Возникла необходимость переработать виноград таким образом, чтобы полуфабрикат для изготовления напитков выдерживал длительные сроки хранения и транспортировку, отличался высоким качеством и имел небольшую массу. Разработана технология получения виноградных криопорошков, которые можно использовать в качестве пищевых добавок, для изготовления восстановленных соков и напитков. Целью исследования было создание инновационной технологии производства криопорошков для получения безалкогольных напитков. Объектом исследования стал виноград дагестанских технических, столовых и изюмных сортов. Алгоритм получения криопорошков соответствовал предложенной автором схеме: доставка винограда, отделение гребней, инспекция, мойка, дробление, замораживание жидким азотом, обезвоживание в вакуумной СВЧ-установке, криоизмельчение и фасовка. При выполнении работы определяли качественный состав сырья и криопорошков с использованием аналитических приборов и лабораторного оборудования кафедры технологии продуктов питания и учреждений Дагестанского научного Центра РАН. Определен химический состав криопорошков, полученных из винограда, выращенного в горно-долинной зоне Дагестана. Приведены физико-химические показатели напитка из криопорошка винограда. Органолептические показатели изготовленных виноградных напитков подтвердили их высокие качественные показатели. Climatic conditions in most of the Russian Federation do not allow growing grapes in the open field, therefore they are imported from the southern regions of the country. The production of grape drinks is usually concentrated in places where grapes are grown, since the delivery of finished products to the northern regions is associated with significant financial costs. Winegrowers of the Republic of Dagestan grow about 30% of grapes throughout the country, and the area of fruit-bearing vineyards occupies more than 20 thousand hectares. There was a problem to process grapes in such a way that the semi-finished product for the production of drinks withstands long storage and transportation periods, is of high quality and has a small weight. A technology has been developed for producing grape cryopowders, which can be used as food additives, for the production of reconstituted juices and drinks. The aim of the study was to create an innovative technology for the production of cryopowders for the production of soft drinks. The objects of the study were Dagestan common and raisin grapes. The algorithm for obtaining cryopowders corresponded to the scheme proposed by the author: delivery of grapes, separation of ridges, inspection, washing, crushing, freezing with liquid nitrogen, dehydration in a vacuum microwave unit, cryo-grinding and packaging. When performing the work, the qualitative composition of raw materials and cryopowders was determined using analytical instruments and laboratory equipment of the Department of Food Technology and institutions of the Dagestan Scientific Center of the Russian Academy of Sciences. The chemical composition of cryopowders obtained from grapes grown in the mountain-valley zone of Dagestan has been determined. The physical and chemical parameters of a wine drink made from grape cryopowder are given. The organoleptic characteristics of the produced wine drinks confirmed their high quality indicators.

Currently, there is great demand to implement circular economy principles and motivate producers of building materials to integrate into a closed loop supply chain system and improve sustainability of their end-product. Therefore, it is of great interest to replace conventional raw materials with inorganic or organic waste-based and filler-type additives to promote sustainability and the close loop chain. This article investigates the possibility of bottom waste incineration ash (WA) particles to be used as a flame retardant replacement to increase fire safety and thermal stability under higher temperatures. From 10 wt.% to 50 wt.% WA particles do not significantly deteriorate performance characteristics, such as compressive strength, thermal conductivity, and water absorption after 28 days of immersion, and at 32 °C WA particles improve the thermal stability of resultant PU foams. Furthermore, 50 wt.% WA particles reduce average heat release by 69% and CO2 and CO yields during fire by 76% and 77%, respectively. Unfortunately, WA particles do not act as a smoke suppressant and do not reduce smoke release rate.

In recent years, a new market trading in cryptocurrencies and instruments based on them has been formed. The market of This paper The goal of the study is to analyze the degree of differentiation of the Arctic regions of Russia by the key indicators of socioeconomic development, dependence of their economic development on the raw materials industries, which should be accounted to shape an efficient regional policy by the state and achieve the strategic goals for the reclamation and development of the Russian Arctic zone. The methodology of the study is based on a systematic approach to assessing the socioeconomic and sectoral differentiation of the Arctic regions of Russia. A set of general scientific and special research methods was used. The conducted analysis indicates that all the Arctic regions under study have a narrow raw materials nature of the economy, the sectoral structure is poorly differentiated. The policy of equalizing the per capita income and the cost of living in the Arctic regions with other regions of Russia largely determined the outflow of population from the northern regions. The state regional policy in relation to the Arctic regions should take into account their heterogeneity in order to achieve the results outlined in the strategic documents.
