Vulcanised rubber as a complex system is made from the basic component being virgin rubber and various components amounting to 10-15 per cent or even more. The material gains its most valuable properties in the final phase of processing i.e. vulcanisation. In mechanical as well as automotive engineering it is important for vulcanised rubber to be resistant to grease, oil and fuel in high operating temperatures. Being one of the very valuable isolation materials, vulcanised rubber is also characterised by dielectric and elastic properties as well as distinguished resistance to operating conditions (high/low temperature, weather conditions). All the above mentioned applications of vulcanised rubbers are also found in the shipyard industry. Their use is also very much predicated on the properties such as: ability to attenuate mechanical vibrations, high elasticity, considerable elastic deformability under static and dynamic loads, low permeability of water and gas, resistance to various chemicals, and other. The purpose of this article was to determine the hardness of vulcanised rubber samples obtained from various places on the "Izabel" inland barge. The scope of the study covered sampling and preparing the samples for testing (i.e. cleaning and degreasing the samples). Then, the hardness of the samples was measured using the Shore hardness test. The first part of the article presents the general concept of vulcanised rubber, its main components, properties, applications, and ageing. The second part focuses on the research scope and measuring the hardness of vulcanised rubber samples obtained from the "Izabel" inland barge. (original abstract)

The paper concerns research and improvement of production processes in one of the European companies in the rubber industry. The main goal is to improve the production process of the thermo-plastics obtained from polymer materials on the company's production line. Improvement is defined as a reduction of the setup time of a key machine in the tested production process. The research method includes the analysis of the literature, observation of the studied process, and the accomplished computer simulation experiments. The proposed activities relate to the reinforcement of the key part of the machine, the change of the machine setup method, and the preliminary staff assignment to the specific tasks. The results of the simulation experiments confirm the implementation of the proposed improvements. The theoretical contribution to the research field development is the proposal of the simulation modeling methodology to improve production processes of continuous materials. Practical conclusions lead to recommendations for the implementation of improvements in the enterprise, with direct application of the proposed actions. (original abstract)

The issue of rubber waste management, among others, due to the intensively developing branch of road transport, and hence a large number of manufactured car tyres, is particularly important for the sustainable development paradigm. Tyres are used not only in internal combustion cars, but also in electric cars, which are considered more ecological. Worn car tyres are not the only type of rubber waste; however, due to the scale of production, they occur most often. The article discusses laws related to this group of waste and methods of its recovery and recycling. All discussed methods of disposal of rubber waste have been characterised in terms of their advantages and disadvantages. An innovative, newly designed pyrolytic installation has also been discussed.(original abstract)

The automotive industry is one of the fastest growing sectors and therefore places demand on many other sectors and increases the need for cooperation. With the development of the automotive industry, tires have become an integral part of society and the everyday life of the individual. As a result of the company's development as a connection of transport, the demand for tires is increasing and the production of waste tires is also related to this. The use of end-of-life tires is almost endless and that is why tires are good to use in the circular economy. The circular economy is an economic system that aims to keep products and materials in use for longer, thus increas-ing their productivity and reducing waste. The paper presents a methodical concept of the plan for the extension of production capacities of rubber-based pressed products with the intention to produce noise reduction panels. The investment consists of the acquisition of the pressing machine and respective mould in the amount of € 180,000. Based on the selected assessment methods it can be stated that the NPV reaches + 69,360 €, Profitability index is 1.38, Internal Rate of Return is 23.8% and the payback period is estimated for 4 years and 4 months, at the considered production capacity of 14,000 m2/year.

Purpose: The primary aim of the article is to present, examine and discuss an alternative approach to the eco-innovation measurement of enterprises, based on the methodology of life cycle assessment (LCA). Design/methodology/approach: The simplified three-step approach, based on the LCA methodology, was applied to perform the analysis. It consists of the following subsequent stages: environmental assessment, environmental profile of an enterprise and contribution analysis. The environmental profile of the enterprise was calculated using the ReCiPe Midpoint (H) method. Findings: A medium size enterprise manufacturing rubber granulates (ethylene-propylene- diene monomer, EPDM and styrene-butadiene rubber, SBR) was covered by the research. The research proved that the analysed enterprise has the most detrimental impact on the environment in the following impact categories: marine ecotoxicity, natural land transformation and freshwater ecotoxicity. These result predominantly from SBR rubber granulate production. Consequently, due to the specificity of the manufacturing process to be more eco-innovative, the enterprise needs to apply more energy-efficient technologies. Originality/value: This is a fully original research paper that validates an alternative approach to measure and stimulate the implementation of eco-innovation at the micro-level. It complements the currently existing methodologies by taking life cycle and the supply chain perspective into consideration, and thus supports decision-makers in the implementation of the principles of circular economy.

Łączna sprzedaż wyrobów gumowych różnorodnych zastosowań przekracza w Polsce 400 mln USD, jednakże udział krajowych producentów na tym rynku spadł do ok. 35 procent w roku 2000. Tracąc krajowych odbiorców polscy wytwórcy z coraz większym powodzeniem zdobywają rynki zagraniczne. W roku 2001 wartość eksportu wzrosła o 38 procent a przez ostatnich 6 lat aż czterokrotnie. Tak w kraju, jak i za granicą branża gumowa zależna jest od ogólnej koniunktury gospodarczej.
