Purpose: to develop a proprietary typology of a business network based on a systematic literature review. Design/methodology/approach: the typology method facilitates the analysis and understanding of the essence of business networks by identifying and characterizing their different types. The systematic literature review (SLR) methodology was used to develop the typology, enriched with the snowball method. Findings: analysis of the content of publications selected during the SLR procedure made it possible to indicate various criteria for the division and types of business networks from widely quoted literature. On this basis, a typology of business networks was proposed, divided into four main types: networks originating from industrial districts, strategic networks, cooperation networks, and global business networks. Practical implications: the possibility of using the proposed concept in assessing various business network models will enable the formulation of diagnostic findings and comparative and dynamic research. Originality/value: at the current stage of scientific reflection, the developed typology enriches the theory of organizational networks by systematizing and comprehensively addressing business network models, which may lead to identifying trends in their development. It is addressed to both researchers dealing with network issues and practitioners.

Łupiny orzechów laskowych, produkt uboczny przemysłu spożywczego, mają znaczny potencjał jako prekursor do produkcji węgla aktywnego ze względu na ich dużą dostępność i dużą zawartość węgla. Przedstawiono badania możliwości przekształcenia łupin orzechów laskowych w węgiel aktywny, wykorzystany do oczyszczania ścieków z zanieczyszczeń organicznych. Porównano procesy aktywacji fizycznej i chemicznej otrzymanego węgla. Otrzymano wysoce porowaty materiał o powierzchni właściwej 1211 m²/g. Ponadto przedstawiono izotermy adsorpcji i oznaczono pojemność adsorpcyjną biowęgla względem rodaminy B.

Hazelnut shells were pyrolyzed at 500°C for 1 h. The obtained biochar was activated phys. with CO₂ at 800°C or chem. with KOH at 850°C. A porous material with a sp. surface area of 1211 m²/g was obtained. The adsorption properties of activated C were tested in relation to the adsorption of rhodamine B. The adsorption capacity was 64.4 mg/g. The Langmuir, Freundlich, Sips and Toth adsorption equil. models were used to describe the rhodamine adsorption isotherm. The best fit to the exptl. data was observed for the Sips isotherm.

Purpose: Technological changes determined by the development of Industry 4.0 significantly change the business models of modern organizations. The Covid-19 pandemic is also influencing changing organizational systems and dynamic progress in technological transformation. The main purpose of the paper is to present the impact of digital transformation on changes in business models and to answer the question if Covid-19 will accelerate change. Design/methodology/approach: The paper contains the literature review on business model concept, Industry 4.0, Digital Transformation and Covid-19. In this paper the empirical study is also presented. The main research problem was to determine the impact of the digital transformation (technological progress) following the Covid-19 pandemic on changes in the business models of Polish enterprises and public sector institutions. Findings: A research confirmed that the digital transformation (processes connected with digitization, automation, robotization and artificial intelligence) resulting from the Covid-19 pandemic has had an impact on the business models of both Polish enterprises and public sector institutions. The research also confirmed a discrepancy between the opinions of experts and management when it came to assessing the impact of technological progress associated with Covid-19 on the business models of the surveyed organizations. Originality/value: The presented work is an important contribution when it comes to the post pandemic economic reality. Paper assesses the impact of technological progress induced by Covid-19 on changes in the functioning of individual processes, which can be an important guide for management practitioners, helpful in implementing modern technological solutions in organizations.
