THE IMPACT OF POLYMER RAW MATERIALS FROM THE RECYCLING PROCESS ON THE STRENGTH OF CONNECTORS IN NON STRUCTURAL APPLICATIONS

Waste materials have become a serious problem in many branches of industry, including also civil engineering. The amount of waste generated in civil engineering is still growing, and therefore, the application of recycling in the construction industry is highly justified. In the present paper we demonstrate the effects resulting from the application of polymer raw materials from the recycling process. It particularly involves the recycling of raw materials from polypropylene applied in the

RECYCLING OF POLYMER WASTE IN THE CONTEXT OF DEVELOPING CIRCULAR ECONOMY

return to production through the allocation of useful fractions and disposal of irretrievable waste. Thus, waste recycling, as a component of a waste management system, can be considered as the most important, necessary, essential, inalienable property of the fourth industrial revolution. According to the Antimonopoly Committee of Ukraine in 2016–2017 no more than 5.8% (2.8 million m3 or 638 thousand tons) of garbage was received for recycling, of which 2.7% was utilized by thermal processing, and

RECOVERY OF TANTALUM FROM DIFFERENT RESOURCES

RECYCLING Tantalum can be extracted as a by-product of tin smelter waste. Tantalum produced in this way is around 14 percentage of total tantalum production [7]. Tantalum is extracted from cassiterite placer middling using shaking tables, and magnetic and electrostatic separation methods [8, 9]. Tin smelter waste typically contains 8 to 10 per cent tantalum oxide, although exceptionally this may rise to 30 per cent [10]. Low grade smelter waste can be upgraded by electro thermic reduction yielding a

FEATURES OF MUNICIPAL WASTE MANAGEMENT IN THE CONTEXT OF SUSTAINABLE DEVELOPMENT IN THE COUNTRIES WITH HIGH GNI PER CAPITA AND LOWER MIDDLE GNI PER CAPITA ON THE EXAMPLE OF FINLAND AND UKRAINE

. Solving the problem of waste reduction, recycling and disposal of accumulated waste has become vital for the world’s population. These factors have forced humanity to make decisions on changing the paradigm of its development for the transition from the “consumer society” to the “sustainable society”. The concept of sustainable development was adopted at the UN Conference on Development and Environment in Rio de Janeiro in 1992 [2]. Sustainable development (SD) “meets the needs of the present without

Design of Pellet Recycle Scraper System in Sand-Blasting Chamber

In the process of industrial sand-blasting, it is necessary to recycle the pellet. In order to solve the existing problems such as high cost, vulnerability, maintenance difficulty and low recycle efficiency in pneumatic recycling system and mechanical recycling system of pellet, we designed a trapezoidal scraper recycle system of pellet which powered by the cylinder and controlled by PLC to realize the pellet collection. The core component of the system is the scraper mechanical structure which

must ensure a certain degree of reduction of the amount of municipal waste in relation to the level of production in 1995. The levels of reduction of biodegradable waste should be ensured in such a way that no later than 15 years after the introduction of the provisions of the Directive, municipal biodegradable waste intended for landfills is reduced to 35% of the total weight of waste produced in 1995 [4–7]. 2. ORGANIC WASTE SOURCES AND RECYCLING According to the Central Statistical Office, in

ASSESSMENT OF THE WASTE MANAGEMENT SYSTEM IN KRAKOW AS AN ELEMENT OF CIRCULAR ECONOMY

1. INTRODUCTION On 2 December 2016, the European Commission adopted an ambitious new circular economy package to help European businesses and consumers transition to a stronger, more circular economy, where resources are used more sustainably. The actions proposed by the Commission will help to “close the loop” of the life cycle of products by increasing recycling and reuse, and bring benefits to both the environment and the economy. These actions will maximize value and ensure the use of all

RARE EARTH ELEMENTS IN RAILWAY INFRASTRUCTURE – POTENTIALS FOR AN INFORMATION SYSTEM AS A TOOL FOR OPERATORS AND OTHER STAKEHOLDERS

which can be life threatening or harmful. This contribution presents a new systematic approach for analysis of rare earths in the field of railway infrastructure. This fills the gap of studies in the sector of railway infrastructure regarding identification, substitution, recycling and innovation to replace these elements, which are well performed in other fields of technology and industry. This paper first provides the basics of rare earths and analyses their relevance in the sector. Furthermore

The mass from the separate collection increased for three municipalities from 2014, showing a positive impact of the new regulations considering secondary raw materials for recycling. In the five years of the study, the variable purchase prices of recyclable materials adversely affected the economic efficiency of the

A resource-conserving serologic and high-throughput molecular approach to screen for blood donors with an IN:−5 phenotype

resource-conserving Nirantara approach, as reported earlier, by recycling the antibody.9 In brief, the test was initially performed as usual by mixing equal volumes of antiserum, LISS, and the donor’s RBC suspension and incubating for 15 minutes at 37°C; the results were read after centrifugation. The test was centrifuged, and the TS was saved. In a separate procedure, the sensitized RBCs from the test were pooled, and an eluate was prepared by the ether elution method. The eluate antibody was mixed
