The main objective of the article is to assess the impact of the variable, which is the level of energy efficiency and the financial aspect of the acquisition and operation of zero-emission electric motor boats against the background of their market substitutes in the form of conventionally powered boats in the face of the phenomenon of development and further market expansion of producers of electric motor boats in Poland in conditions for meeting contemporary environmental demands for sustainable development. This goal was achieved taking into account the results of the study carried out taking into account the descriptive and comparative analysis of energy, environmental and economic conditions for the development of a research and development project conducted in 2018–2019 by VT-Sport, concerning the development of a new model of a motorboat along with preparation for implementation into production. The result of the study was an indication of market needs in the scope of further development and expansion of domestic producers of electric drives for motor boats in Poland. The results of the research may constitute a significant contribution to in-depth research and discussions in the field of meeting the conditions and postulates of ecological, economic and social sustainable development in the considered sector of the economy.

Streszczenie: Głównym celem artykułu jest ocena wpływu zmiennej, jaką jest poziom efektywności energetycznej oraz aspektu finansowego nabycia i eksploatacji łodzi motorowych o zeroemisyjnym napędzie elektrycznym na tle ich substytutów rynkowych w postaci łodzi o napędzie konwencjonalnym wobec zjawiska rozwoju i dalszej ekspansji rynkowej producentów łodzi motorowych w Polsce w warunkach spełnienia współczesnych postulatów środowiskowych zrównoważonego rozwoju. Cel ten został osiągnięty z uwzględnieniem efektów badania opartego na analizie deskryptywnej i komparatywnej uwarunkowań energetycznych, środowiskowych i ekonomicznych rozwoju projektu badawczo-rozwojowego prowadzonego w latach 2018–2019 przez firmę VT-Sport dotyczącego opracowania nowego modelu łodzi motorowej wraz z przygotowaniem do wdrożenia do produkcji. Wskazano potrzeby rynkowe w zakresie dalszego rozwoju i ekspansji krajowych producentów łodzi motorowych w Polsce. Efekty badania mogą stanowić istotny przyczynek pogłębionych badań i dyskusji na temat spełniania warunków i postulatów ekologicznych, ekonomicznych oraz społecznych zrównoważonego rozwoju w rozważanym sektorze gospodarki.

Nowadays, achieving of sustainable development became impossible without effective, both from an environmental and from an economic view, solution of the problem of recycling of solid waste. The paper gives an overview of the ecological and economic efficiency of the main existing methods for utilization of solid domestic waste, namely, incineration in combustion plants, biothermal composting, pyrolysis, plasma gasification, use of combined methods. The essence of the widespread methods of utilization of solid domestic waste, their scope. The main drawbacks of the existing methods of solid domestic waste utilization were also outlined: such incineration in combustion plants is the most appropriate from the economic point of view, but poorly solves the problem of environmental pollution, because a significant part of harmful substances do not burn at temperatures used in incineration plants and the process is accompanied by a significant amount of emissions of harmful substances and carbon dioxide into the atmosphere; when using a biothermal composting, debris, with all heavy metal impurities, radioactive and other possible harmful substances, is just applied to the fields as a fertilizer or in a greenhouse as a biofuel; when pyrolysis is used, the unit's capacity for the process to dispose of household waste cannot be large; to carry out the process of pyrolysis of such low-calorific fuel as solid household waste, considerable additional energy resources are required, which causes high operating costs; the process of plasma combustion to neutralize domestic waste is quite energy intensive, which is why it is not currently self-supporting at the moment.
