The main aim of the paper is to analyse and evaluate the possible relation between circular behaviours undertaken by the households and the socio-economic features describing them. The paper presents the results of the author’s research conducted among Polish households on the territory of two voivodeships: Podkarpackie and Małopolskie. In the article, the author presents the concept of circular behaviours (understood as an element of pro-ecological behaviours), as well as the result of the preliminary analysis of the frequency of exhibiting those behaviours in the households. This analysis is based on evidence regarding the possible differences between the households due to their distinct features. To indicate the possible differences the Chi2 Test of Independence was used. Obtained results indicate that some socio-economic features may have an influence on the frequency of conducting circular behaviours. It could be important due to the establishment of supporting activities aiming at increasing the overall level of circularity among households (as an economic sector). This article is the fourth one in the publication series devoted to circular economy and sustainable development matters.

Aquaculture Production

Following the growth of the global population and the subsequent rapid increase in urbanization and industrialization, the fisheries and aquaculture production has seen a massive increase driven mainly by the development of fishing technologies. Accordingly, a remarkable increase in the amount of fish waste has been produced around the world; it has been estimated that about two-thirds of the total amount of fish is discarded as waste, creating huge economic and environmental concerns. For this reason, the disposal and recycling of these wastes has become a key issue to be resolved. With the growing attention of the circular economy, the exploitation of underused or discarded marine material can represent a sustainable strategy for the realization of a circular bioeconomy, with the production of materials with high added value. In this study, we underline the enormous role that fish waste can have in the socio-economic sector. This review presents the different compounds with high commercial value obtained by fish byproducts, including collagen, enzymes, and bioactive peptides, and lists their possible applications in different fields.

First Time

For the first time in the scientific literature, this research shows an analysis of the implementation of circular economy techniques under sustainable development framework in six municipalities with a depressed economy in Colombia. The analysis is based on solid waste data production at a local scale, the valuation of the waste for subsequent recycling, and the identification and quantification of the variables associated with the treatment and final disposal of waste, in accordance with the Colombian regulatory framework. Waste generation data are obtained considering three different scenarios, in which a comparison between the simulated values and those established in the management plans are compared. Important differences have been identified between the waste management programs of each municipality, specifically regarding the components of waste collection, transportation and disposal, participation of environmental reclaimers, and potential use of materials. These differences are fundamentally associated with the different administrative processes considered for each individual municipality. This research is a good starting point for the development of waste management models based on circular economy techniques, through the subsequent implementation of an office tool in depressed regions such as those studied.

AbstractThe implementation of circular economy in wood industries is an effective way for future sustainable development. The wood industries in China are not in the direction of circular economy approach due to less availability of assessment/calculation data of pollutants as per life cycle assessment (LCA) criteria. The present study focuses on the calculation of emission and pollutants from wood industries as per LCA; the emission and pollution data were collected from fiberboard Medium-density fiberboard (MDF), plywood and particleboard (PB) production. The comparative analysis of dust emissions, industrial waste gases and chemical oxygen demand (COD) were performed among three wood industries. The results revealed that the fiberboard industry was the highest emitter of dust, industrial waste gas and COD; and particleboard industry was the least emitter. Further, results indicated that pollutant index of wood industries were significantly changed between 2015 and 2017; the industrial waste water discharge increased five folds and the COD, dust and industrial gases increased two times. This study provides with the emission and pollutants data of wood industries as per LCA to promote the sustainable development for circular and low carbon economics.

Sustainable Future

The increasingly stellar attraction of the digital technologies and the growing, though not universal, consensus of the need to build a sustainable future, are two powerful trends within society. The aim of this article is to offer an exploratory review of how the leading companies within the digital transformation market have addressed sustainable development. As such, the article’s originality and value lie in offering a review of current corporate thinking within that market. The study adopts an inductive, qualitative approach based on an examination of published company reports, and identifies six major sustainability themes being actively promoted and supported. The article concludes that the current sustainability objectives of the technology companies are driven as much by commercial reality as any altruistic motives, and that support and promotion of the circular economy may offer the best opportunity for digital technologies to meaningfully impact sustainable development.

Beginning with the increasingly serious situation facing human society, it describes the origin and meaning of ecological circular economy; after that, it focuses on the three main principles of the eco-circular economy, they are reduction, reuse and recycle principles. Then, it analyzes the eco-circular economy further from the angle of industrial technology and economic dimensions, summarizes the barriers to the development of eco-circular economy. Finally, the paper elaborates a number of measures in the establishment of eco-circular economy.

Circular Design

Food, the basic connecting unit of all the UN's Sustainable Development Goals, plays a crucial role in the ecological transition towards a circular economic paradigm. This paper takes scientific considerations as a starting point in order to contribute to the definition of a theoretical-operational framework in which to grow the Circular Economy for Food. This is a still-open question in a sector of the circular economy that is emerging as vital to sustainable development. The 3 C's of Capital, Cyclicality and Co-evolution offer a systemic, holistic vision of the food system's role. Within this conceptual framework, the designers can find the main boundaries of the system, within which to express their creativity. The aim must be to avoid damaging relationships with the best supplier of raw material known to humanity (Nature), respecting planetary boundaries and at the same time offering a fair space to civil society.
