Content available remote Zielona chemia - zrównoważona chemia: perspektywy rozwoju
100%
PL
Omówiono filozofię zielonej i zrównoważonej chemii, wpisujących się w paradygmat zrównoważonego rozwoju cywilizacji. Podano definicje pojęć: „zielona chemia”, „zielona inżynieria”, „zrównoważona chemia” oraz podkreślono ważność zawartych w nich propozycji dla dalszego rozwoju przemysłu chemicznego. Zwrócono uwagę na próby określenia miar ilościowych zrównoważonego procesu chemicznego oraz na aspekty społeczne z nim związane.

Heterogeneous catalysis is one of the fastest developing branches of chemistry. Moreover, it is strongly connected to popular environment-related applications. Owing to the very fast changes in this field, for example, numerous discoveries in nanoscience and nanotechnologies, it is believed that an update of the literature on heterogeneous catalysis could be beneficial. This review not only covers the new developments of heterogeneous catalysis in environmental sciences but also touches its historical aspects. A short introduction to the mechanism of heterogeneous catalysis with a small section on advances in this field has also been elaborated. In the first part, recent innovations in the field of catalytic air, water, wastewater and soil treatment are presented, whereas in the second part, innovations in the use of heterogeneous catalysis for obtaining sustainable energy and chemicals are discussed. Catalytic processes are ubiquitous in all branches of chemistry and there are still many unsolved issues concerning them.

Since the beginning of the 1990s, environmental protection has played an increasingly important role both in the chemical industry and in the scientific work of chemists in the academic world. A noteworthy feature of the so-called green chemistry and sustainable chemistry is the emphasis that practitioners of both disciplines lay on codifying the principles, rules, and characteristics that environmentally friendly chemical reactions and processes should meet. These codifications have a complicated epistemological status: they aim to set the criteria of ‘greenness’, indicate the direction of scientific development, and build the foundations for new research programs. While the most famous of these codifications are the twelve principles of green chemistry developed in the United States in 1998, successive attempts to codify a new type of environmentally friendly chemistry have been regularly made over the last twenty years – not only in the United States but also in Germany. Starting with American green chemistry, through German ‘soft chemistry’ (sanfte Chemie) and chemistry for sustainable development, and ending with circular chemistry, this article is an attempt to familiarize the Polish reader with this new tool in the work of researchers and engineers. Its purpose is to pay particular attention to the context of the creation and interpretation of consecutive sets of rules of a new type of chemistry and the challenges related to their application.
