Eco-design is one of the cornerstones of the modern economy, as reflected in the policies aimed at implementing the principles of design for the environment in the European Union legislation. A life cycle perspective is a feature of eco-design. The study aimed to determine whether and to what extent the selected companies operating in manufacturing sectors consider life cycle perspectives when designing and developing the products they offer. The main research area discussed in the following article focused on the question: What kind of activities related to the idea of life cycle thinking in product policy can be identified in the analysed enterprises? Qualitative research was conducted using the individual in-depth interview method with representatives of selected industries located in Poland. Eight manufacturer groups were invited to participate in the study. Based on the recruitment process, 24 companies were chosen for the interview. Individual in-depth interviews were conducted using Microsoft Teams, following the ICC/ESOMAR Code 2016 standards. Based on the results, most companies that participated in the study considered the life cycle perspective when designing or further developing products. However, their activities varied in scope. The activities of the ten interviewed companies could be regarded as advanced. For six companies, the advanced activities targeted the product’s use phase. Two companies undertook such activities at more than one life cycle stage. The study provides evidence that the surveyed companies are beginning to think beyond operational boundaries and changing their pro-environmental orientation, albeit unimpressively. The paper provides evidence that eco-design requirements are an unquestionable driver for activities from a life cycle perspective. All surveyed manufacturers of energy-powered products are taking measures to reduce energy intensity with less activity, for example, ensuring the durability/ reliability of products and finding solutions to facilitate disassembly and recycling.

Środowiskowa ocena cyklu życia (LCA) jest techniką zarządzania środowiskowego, która ze względu na swój potencjał może znaleźć wiele obszarów zastosowań. W literaturze przedmiotu podkreśla się jej istotną rolę w aspekcie zwiększenia efektywności gospodarki odpadami. Niniejszy artykuł stanowi głos w dyskusji na ten temat, a jego nadrzędnym celem jest przedstawienie LCA w kontekście realizacji gospodarki o obiegu zamkniętym oraz ocena szans popularyzacji tej koncepcji w Polsce. Na podstawie wyników własnych badań ankietowych wykazano, iż zdecydowana większość respondentów wprawdzie zapewniła o poczuciu swojej świadomości ekologicznej, niemniej jednak niewiele ponad 60% ankietowanych zadeklarowało systematyczną segregację odpadów komunalnych. Budowanie zatem gospodarki o obiegu zamkniętym w Polsce wymaga zwiększenia zaangażowania społecznego oraz odpowiedniej edukacji w tym zakresie.

Life Cycle Assessment (LCA) is an environmental management technique, which provides a whole range of possible fields of application. In literature, it is emphasized that LCA playes a significant role in terms of increasing the efficiency of waste management. This article joins the discussion. Its aims are to present LCA in context of the Circular Economy and to assess the chances to popularize this concept in Poland. The presented results of the survey show that the majority of respondents asserted their environmental awareness, however, a little over 60% of respondents declared that they systematically segregate waste. Creating the Circular Economy in Poland therefore requires the public's involvement and an adequate education in this field.

Environmental Life Cycle Assessment (LCA) is an environmental management technique which, because of its potential, can be applied in many different areas. Its key role in increasing the efficiency of waste management is emphasised in the literature on the subject. This paper intends to make a contribution to the discussion on this subject and its primary goals are to present LCA in the context of implementation of circular economy and to assess the chances of popularisation of this concept in Poland. Based on own survey results, it was demonstrated that while the vast majority of respondents assured of their sense of environmental awareness, a little over 60% of respondents stated that they systematically segregate municipal waste. Thus making the transition towards a circular economy in Poland requires the increase in public's involvement and adequate education in this field.

The present article touches upon the topic of LCA simplifications within the scope of data inventory for the purposes of life cycle analysis of selected products. The paper’s main objective was to define the features of products for which the calculation of the simplified environmental indicators may be recommended. The selected products differed in many aspects, and they could be generally classified into two separate groups: active products, which require energy to fulfil their function, and passive products, which do not need an energy supply. On the basis of the presented active products, it has been established that the key issue during their classification should be mass per unit and operational mode. The features of the analysed active use-intensive products include: low mass per unit, relatively short life cycle related to intensive use, possibility for fulfilment of functions without additional material flows and operation with constant AC power supply. A simplified LCA should be recommended at the first stage of project planning, when there are many versions/conceptions of a given product and when a full LCA is virtually impossible. In light of the above-mentioned, simplified environmental indicators would be the first filter for the versions of a new product being considered. Thanks to the proposed approach, the designer is able to categorise the tested product and will be aware of any potential critical points of its life cycle (hot spots).
