Life Cycle Assessment, included in company environmental management methods, has particular importance in marketing management. Analysis of dangers to the environment through tools such as the LCA method allows for comparisons of alternative company management strategies. LCA is characterised as a technique for environmental management that enables environmental impact assessment of the product, process, industry, and even the comprehensive economic sector. LCA also influences decisions regarding environmental policy modification, but most importantly, it influences a company's marketing activities. The LCA technique is applied the world over with great effectiveness in studying specific phases of a product's life cycles – from 'birth to death'; however, Poland's experience in this domain constitutes continuously developing research areas. The experience of foreign research centres confirms the possibility of applying LCA techniques in supporting environmental risk assessment of innovative technologies where LCA is used to study the environmental impact of a new generation product, i.e. flocculants from polymer wastes. This article presents the results of a study of the effectiveness of applying a new generation of polyelectrolyte (gained from polystyrene waste) in treating industrial wastewater and the LCA environmental impact assessment, which was carried out using SimaPro software. Based on the analysis of the results of the application of sodium salts of sulfone derivatives of polystyrene in the treatment of mine water, it was found that these products significantly reduced the pollution indicators of mine water from KWK1. Accordingly, they provided the basis for the development of technical-scale technology.

Due to the high level of losses and food waste nowadays, the problem become global. The main causes of food loss in households are: exceeding shelf life, excessive purchases, damage and low quality, additionally excessive portions of meals, wrong food storage, the bad taste of the product, lack of idea on how to use available ingredients, as well as reckless purchases, too large packaging. Negative effects of food loss can be grouped into three areas: environmental, economic and social, consistent with sustainable development's basic goals. The aim of this article is to present an original proposal for an approach to Lean Society philosophy with respect to the problem of food loss. The authors reviewed conventional and unconventional methods of food preservation, identified available and innovative solutions in terms of reducing food loss and indicated directions and opportunities for reducing food loss on the basis of Lean Society philosophy.

Ze względu na wysoki poziom strat i marnowania żywności w dzisiejszych czasach, problem stał się globalny. Głównymi przyczynami strat żywności w gospodarstwach domowych są: przekroczenie terminu przydatności do spożycia, nadmierne zakupy, zniszczenia i niska jakość, dodatkowo nadmierne porcje posiłków, niewłaściwe przechowywanie żywności, zły smak produktu, brak pomysłu na wykorzystanie dostępnych składników, jak również a także lekkomyślne zakupy, zbyt duże opakowanie. Negatywne skutki utraty żywności można pogrupować w trzy obszary: środowiskowy, ekonomiczny i społeczny, zgodny z podstawowymi celami zrównoważonego rozwoju. Celem artykułu jest przedstawienie oryginalnej propozycji podejścia do filozofii Lean Society w odniesieniu do problemu utraty żywności. Autorzy dokonali przeglądu konwencjonalnych i niekonwencjonalnych metod utrwalania żywności.

In practice, reverse logistics in Poland refers to a narrow approach within the framework of the waste management problem. The voivodships have been obliged to implement reverse logistics processes more effectively through waste management. The article aims to diagnose the implementation level of waste management processes (part of reverse logistics) in Polish voivodships. The research used a multivariate comparative analysis that ranks voivodships according to waste management indicators. The research will result in preparing the ranking of voivodships listing the leaders and those unsuccessful in the implementation of waste management. Based on the research, Śląskie and Podlaskie voivodships were selected as the ones presenting the highest level of waste management implementation, whereas the lowest level was recorded for Lubuskie voivodship.

W praktyce logistyka zwrotna w Polsce, odnosi się do wąskiego podejścia poprzez zagadnienie gospodarowania odpadami. Województwa, zostały zobligowane do efektywniejszej realizacji procesów logistyki zwrotnej, jakim jest gospodarowanie odpadami. Celem artykułu jest zdiagnozowanie poziomu wdrażania procesów gospodarowania odpadami (część logistyki zwrotnej) w województwach Polski. W badaniach wykorzystano wielowymiarową analizę porównawczą, która porządkuje województwa według wskaźników gospodarowania odpadami.
