    Opis:
    The current economy system is based in an intensive consumption of fossil fuels in a way that severely compromise future of the planet due to the severe consequences in climate change. In this scenario, the development of flexible and integrated biorefineries to produce biofuels and bioproducts from renewable biomass sources represent a key tool to perform the transition from a petroleum-based economy to a novel bioeconomy that looks for a more efficient and sustainable global development. This article analyses: the significance of biomass sources (such as agricultural and woody crops and residues, agro-food and wood processing industries residues and urban wastes) as feedstocks in the biorefinery, the most relevant biorefinering process technologies of the biochemical and thermochemical conversion pathways that are nowadays under development, and the need of further research and innovation effort to eventually achieve the commercialization and application in the market of the different biorefinery products.

    Opis:
    One of the key and simultaneously the most difficult issues within the methodology of the environmental life cycle assessment (as well as related life cycle-based techniques) is solving the problem of the multifunctionality of product systems, which includes the questions crucial for the circular economy: reuse, recycling, transforming by-products into valuable (in the market aspect) co-products, prolonging durability. The present paper aims at familiarizing the questions of multifunctionality and presenting the Circular Footprint Formula (CFF), which has been developed within the pilot stage of the European Commission project related to the common methods of measurement and communication the life cycle environmental performance of products and organisations. An example of PET bottles has been presented and two scenarios have been analysed: (1) a scenario with no recycling (a recycling content = 0 and a recycling rate = 0) and (2) a scenario with recycling (recycling content = 0.24 and recycling rate = 0.24). Calculations of life cycle emissions of CO2 have been made by using the CFF formula. An idea of division environmental burdens and credits between supplier and user of the recycled material has been shown and explained as well.

    Opis:
    Currently, within the European Union, the importance of resource efficiency is being highlighted. The issue has been well established within the Europe 2020 strategy and above all within the concept Towards a circular economy: zero waste for Europe'. Using the example of Poland, the authors show changes that have occurred in the management of packaging waste after Poland joined the EU. The data of the Central Statistical Office concerning both municipal and packaging waste allowed to determine changes in waste management and to address them, and the literature on the subject indicates gaps as well as barriers in this area. Building a circular economy (CE) for both packaging goods and waste from packaging in Poland not only requires increasing the involvement of enterprises but also the need for Polish society to be willing to embrace the objectives of the concept of "Zero Waste for Europe" in the European Union.

    Opis:
    Circular economy offers opportunities to boost jobs and tackle climate change. The article reflects aspects of the impact on the environment through sectoral policies to support the circular economy because current business as usual model, based on the linear economy principle leads to a staggering inefficiency in nature resources are managed, with increased pollution, loss of ecosystems and substantial losses of value with each product disposed. This requires a change not only in consumer behaviour but even more on the resource extraction and material production side. The purpose of the research paper is to develop a decision-making matrix providing a step-by-step approach for the policymakers.

    Opis:
    Fuels combustion, polluting the atmosphere is a side effect of an engines’ work. Increasing ecological awareness has led to constant pursuit of disposing harmful substances properly. Catalytic converters (car catalysts), containing precious metals from the platinum group, including palladium, platinum and rhodium, have been commonly adopted for this purpose. These critical elements can be found in many raw materials used frequently throughout the economy. Therefore, it is economically viable to retrieve these elements from, among the others, spent catalysts, so they can be reused to manufacture new converters. In order to determine a possible cost of spent car catalyst, it is essential to use the analytical techniques to determine elemental content in any given sample. X-ray fluorescence spectroscopy (XRF) is an example of such a technique. It is nevertheless advisable to use a complementary procedure to confirm any results obtained. A cross-verification technique was developed using inductively coupled plasma mass spectrometry (ICP-MS). This procedure was verified using comparative studies, which confirmed its usefulness and correctness.

    Opis:
    The concept of sustainability is attracting great attention as societies become increasingly aware of the environmental consequences of their actions. One of the most critical challenges that humankind is facing is the scarcity of resources, which are expected to reach their limits in the foreseeable future. Associated with this, there is increasing waste generated as a consequence of rapid growth in the world population (particularly inurban areas) and aparallel rise in global income. To cope with these problems, a linear strategy has been applied to increase efficiency by reducing the use of materials and energy in order to lessen environmental impacts. However, this cradle to grave approach has proven inadequate, due to a lack of attention to several economic and social aspects. A paradigm shift is thus required to re-think and innovate processes (as early as inthe design phase) in such a way that materials and energy are used more effectively within aclosed-loop system. This strategy, known as the cradle to cradle approach, relies on the assumption that everything is aresource for something else since no waste is ever generated in nature. In line with the cradle to cradle approach, the bio-inspired circular economy concept aims at eco-effectiveness, rather than eco-efficiency. While the circular economy has neither a confirmed definition nor a standardized methodology, it nonetheless carries significant importance, since it “is restorative and regenerative by design and aims to keep products, components, and materials at their highest utility and value at all times, distinguishing between technical and biological cycles,” in accordance with the goals of the 2030 Agenda for Sustainable Development. Despite some controversial opinions that “circles are not spirals, and for growth to occur, spirals with ever-increasing radii are required,” the circular economy concept is taking a central role in the sustainable development debate and, for this reason, deserves attention. The aim of this paper is to shed light on this debate, pointing out the main features of the emerging circular paradigm along with sustainability transition theories and circularity evaluation tools.

    Opis:
    An integrated system combining volumetric coagulation and nanofiltration (NF) was proposed as the high-efficiency wastewater treatment technology. In this study, biologically treated coke wastewater (after denitrification and nitrification processes) coming from a coke plant located in Silesia (southern Poland) was used. The results indicate that the use of integrated membrane processes allows to achieve high efficiency of wastewater treatment. The treated wastewater can be converted back and used as technical water in the coke plant, in accordance to ‘zero waste’ strategy.

    Opis:
    This paper explores the global dynamics of second-hand clothing (SHC) in light of the circular economy to identify gaps and suggest pathways to reduce negative impacts on the sector. The analysis identifies current global patterns of SHC international trade and the main hotspots, in order to build a framework for action. The framework incorporates the main stakeholders and a set of actions aimed at reducing the environmental and social issues associated with the international trade of SHC. The analysis suggests that the framework may reduce risks and facilitate the transition to a just circular economy in the SHC sector.
