With a rapidly growing world population and the need to address the issue of consumption of global resource and its associated environmental impacts and other social and economic issues, the demand for a responsible consumption, production and prevention of waste generation become increasingly crucial. With this broad characterization of Sustainable Consumption and Production (SCP), businesses based on circular economy should become the norm. With this goal in mind, an online questionnaire survey was performed on a nationwide scale, to explore consumers’ behaviors and attitudes. It was distributed in all four of Romania’s macro-regions and reached 642 respondents. The purpose of the study has been to better understand consumers’ behavior regarding sustainable consumption and production and examine whether generations play a role in responsible consumer attitudes toward the products. Three generations (X, Y, and Z) have been examined and compared. The results show that what extent those three generation agree with the environment and the benefits of reducing resource consumption, also waste generation, selective collection, recycling and reuse. However, most of them have not adopted and do not intend to adopt consumer patterns based on the circular economy. The findings provide empirical evidence and directions that could help marketers identify their consumer’s characteristics and market segments and develop consumer empowerment strategies on the Romanian market.

The objective of this paper is to analyze the extent to which the system of indicators that is used in the Monitoring Framework for the transition to the circular economy (CE) is efficient and relevant in their contribution to the sustainable development of European communities. The fundaments of the transition framework and the main characteristics of the circularity indicators are presented. A critical review was performed in order to fulfill the objective of analyzing the current indicators. It is concluded that the indicators in the current framework are (as a selection from a very broad range of indicators theoretically proposed and with estimated practical applicability) limited from the perspective of circularity only to waste generation and recycling processes containing recyclable materials, without including important circularity indicators related to the prolonging and extending the life cycle of products and materials. This paper proposes and defines such an indicator, based on the consideration of the fundamental scalars describing economy, mass, energy, time, and value, respectively. The indicator is described and its applicability in all the phases of the economy is estimated.

According to the United Nations, the consumption of materials is expected to double between 2020 and 2050. At the same time, annual waste generation is forecast to increase by 70% by 2050. The circular economy (CE) addresses this problem. However, many barriers to the further development of the CE exist. This article analyses the situation of public procurement in supporting a sustainable CE for tyres in Germany based on 18 interviews with public procurement professionals directly responsible for the purchase of tyres and four additional expert interviews. Based on the dimensions ‘current circular public procurement (CPP) intensity’ and ‘current CPP opportunities’, a classification of tyre procurement situations and barriers to sustainable circular tyre procurement is presented. Strategies to overcome these supply-side and demand-side barriers are specified, resulting in nine recommendations for German policymakers. As a way forward, a detailed concept for a pilot project on tyre CPP is provided. The article also shows how the circular public procurement classification can be used to support sustainability measures in a broader context. Finally, the article’s outlook focuses on implications to promote sustainable circular tyre procurement in other countries. It explains different framework conditions and elaborates to what extent additional research is necessary to develop appropriate recommendations for those conditions.

This chapter examines the structures and principles of waste management law, using several jurisdictions including China, Japan, Australia, New Zealand, the European Union, and the United States for comparison. It first provides an overview of the so-called macrostructures of waste management laws, focusing on three ways in which the broad structure of waste laws can be contrasted: centralized systems versus delegated systems, unified systems versus fragmented systems, and integrated versus specific systems. It then considers the principles of waste management law, with emphasis on approaches taken to define ‘waste’, waste hierarchy, waste streams, and waste classifications. It also describes management principles such as reduction of waste generation, treatment near the source, standards of waste treatment, prohibitions and restrictions of movement, and extended producer responsibility. Finally, it explores the emerging trend of circular economy approaches to waste management.

In this paper, material flows and resource potentials for plastics at a national level in Denmark are mapped using an Environmentally Extended Multiregional Input-Output (EE-MRIO) database. EE-MRIO offers an operative improvement to current and prevalent methods for assessing the industrial and societal metabolism of resources, including plastics. The Exiobase is applied to map (1) the major sources, (2) calculate the total supply, (3) uses of plastics and waste generation, and (4) end of life pathways in order to indicate the potentials of plastics in the circular economy in Denmark with a focus on recycling. Furthermore, it elaborates how and why this method for performing Mass Flow Analysis (MFA) differs from mainstream assessments of material flows and from default uses of national statistical data. Overall, the results are that Denmark has a total supply of ≈551 kilotonnes (Kt) of plastics, out of which ≈522 Kt are used domestically and ≈168 Kt of plastic waste are generated annually. Out of the yearly amount of plastic waste, ≈50% is incinerated and 26% is recycled. These results indicate significant potentials for applying circular economy strategies and identify relevant sectors for closing the plastic loops. However, other initiatives are necessary, such as improvements in product design strategies, in the collection and sorting systems as well as in cross-sectoral collaboration.

The South Korean government’s renewable energy deployment plan aims to increase the share of electricity generated from renewables to 20% by 2030. To reach this goal, the rate of photovoltaic (PV) installation will accelerate in the coming years. This energy transition creates a new challenge: PV wastes. This study estimates the amount of PV waste generated, the material composition of PV waste, and the amount of recyclable metals in South Korea by 2080 under four different scenarios (combining shape parameters of 5.3759 [regular-loss] and 3.5 [early-loss] with PV module lifespans of 25 and 30 years) using the Weibull distribution function. The annual waste generated will fluctuate over time depending on the scenario, but between 4299 and 5764 thousand tons of PV waste will have been generated by 2080. Under the early-loss/25-year lifespan scenario, annual PV waste generation will increase to exceed 130,000 tons in 2045, then decrease through 2063 before increasing once again. The fluctuation in annual PV waste generation appears stronger under regular-loss scenarios. An appropriate system for the monitoring, collection, and storage of PV waste needs to be arranged even before the volume becomes high enough for recycling to be economically viable. International cooperation could be a way to maintain the PV waste stream at an economically feasible scale. It would also be a good idea if the PV module could be designed in a way that would enable easier recycling or reuse.

Circular Economy is a sustainable transition from the current linear thinking to a circular approach. The construction industry is criticized as the first responsible of waste generation and resources consumption, thus, it will be the sector which has potential of adopting the Circular economy approach. Oman construction industry is not an exception, it also negatively suffers from high waste and therefore adopting CE approach will be crucial to enhance the industry reputation and sustainability aspects. According to previous research, the critical challenges facing the adoption of circular economy concept in Oman built environment were introduced firstly with absence of clear vision and legislation supporting CE, as well as, lack of government funding of research, innovation, and investment as governmental barriers, followed by a technical barrier which is absence of qualified professionals in CE in construction industry. The aim of this study is to explore the drivers supporting the adoption CE in Oman Built Environment. An exploratory study was conducted to explore the main drivers of CE in Oman built environment through 10 interviews of the built environment professionals and 80 questionnaire survey responses of built environment stakeholders. The results revealed that the key findings of the critical drivers of adopting CE in Oman built environment are: governmental responsibility through establishment of a clear vision and regulations of CE, upgrade public awareness, being a role model of CE implementation, as well as, establishing of supportive infrastructure for recovery process through collaboration with the private sector. Finally, gaining momentum in CE in Oman built environment shall be initiated by governmental effort to benefit economically, socially and environmentally.

The paper aims to highlight the status of the circular economy implementation in the EU and Ukraine, as well as to determine the advantages, challenges, opportunities and barriers to transition to circular supply chains. The main problems of waste management in Ukraine are explored, including faulty legislation, underinvestment, state policies and enlightenment regarding the circular economy, formal approach to the implementation of programs and strategies that should improve economic conditions, dominance of most waste-generative – extractive – industries in the economic structure of Ukraine. It is found out that the legislative framework for circular- and bio-economics in Ukraine does not meet the global challenges and requirements of the Association Agreement between Ukraine and the EU and needs urgent improvement measures. Studying the EU experience allowed describing the advantages and challenges of a circular economy that emerge in Ukraine. The article presents a mathematical model aimed at describing the peculiarities of a circular economy in the countries with low and high levels of industrial ecologization as well as understanding conditions for resource conservation during production processes. An econometrical model of the correlation between the solid waste generation, GDP and capital investment into environmental protection in Ukraine is used to demonstrate the absence of the latter’s influence on the waste generation at the current technological level of the national industries. The research results allow developing recommendations for state policy for the industrial sector and environmental protection that may be implemented at the current stage to achieve Sustainable Development Goals 2030.
