“…Besides, the circular economy is a sustainable development strategy that tackles the problems of environmental degradation and natural resource shortages through three principles: reduction, reuse and recycling of materials [5][6][7]. These principles define a circular system where all the materials are recycled, and all the energy comes from renewable sources that support activities and rebuild the ecosystem as well as support human health, society and healthy resources that generate value [8][9][10][11].…”

The Sustainability of Romanian SMEs and Their Involvement in the Circular Economy

Sustainability involves extending the relational framework of SMEs outside the sphere of economic activity by justifying and legitimizing actions with a social impact on the environment. Links with the circular economy are achieved through the economic and environmental dimensions and through corporate social responsibility as a component of sustainable development. The main purpose of the paper was to determine the level of involvement of Romanian SMEs in activities related to the circular economy. The sample survey conducted among SME managers offered the advantage of collecting a large amount of direct information on the activities undertaken, the size of the investments and the nature of the funding sources used over the last five years. In this descriptive research, the process of setting up a representative sample of 384 enterprises was carried out by random sampling. The major contributions of the research project are to outline the contribution of Romanian SMEs to the development of a sustainable economy through their involvement in specific activities, the size of the investments made, and the level of participation of representatives of the enterprises in courses in order to identify new sources of financing and positive solutions in order to implement the principles of the circular economy.

“…Several indicators of circular economy that allow to determine the efficiency of the use of resources, the minimization of waste generation and the conversion of pig manure into a technological nutrient are defined hereafter [5,6]. These indicators are considered within the circular economy model applied to the process of pig manure treatment.…”

“…In the circular economy model, waste is turned into resources, which are also called technological nutrients [5,6] and reintroduced into the production processes [7,8]. In this time of great transformations, the objective is to go from lineal economy, where society is based on waste production, consumption, and disposal, to the new model provided by circular economy, which is focused on the principles of the "3 Rs": reduction, reutilization, and recycling of as much waste as possible.…”

Circular economy intends to turn waste into resources that can be reintroduced into the production process, eliminating the negative externalities from it. The impact of pig manure on the environment is one of the main challenges in agriculture. The high amount of pig manure coming from the pig farming industry complicates the management of this type of effluents, leading to a serious impact on the environment, as it pollutes the soil, the water, and the air. The concept of the indicator of circular economy was introduced to evaluate the degree of approximation of the pig manure treatment process to the circular economy model. In light of this, these indicators showed the possibility of obtaining 0.97 m 3 water h −1 , 49.40 kg biofertilizer h −1 , and 5.33 m 3 biogas h −1 per 1 m 3 pig manure h −1 treated, allowing us to assess the minimization of waste generation and the efficiency of the use of resources. By applying an anaerobic digestion process to treat pig manure, reductions of water and natural gas consumptions were 47.01% and 5.33%, respectively, which leads to a reduction in emissions of 171.98 kg CO 2 h −1 . Consequently, pig manure can be considered as a technological nutrient that is reintroduced into the productive system, enabling the recovery of energy, water, and biofertilizer contained therein.

“…It understands the world as a complex interaction between economic, social, environmental and political systems. Management of the environment has been viewed as a determinant of business success [3][4][5][6][7][8][9]. Family business researchers must take environmental issues into consideration as they are increasingly important, especially since the development of theories such as functionality, ecology and development, which incorporate the lens of sustainability [10].…”

Family Businesses Transitioning to a Circular Economy Model: The Case of “Mercadona”

Sustainability addresses environmental and social issues affecting this and future generations. When family businesses perceive that the community is disrupted, recognize an environmental problem and respond by implementing new environmental policies or regulations, the family business's socio-emotional values press to transition to a more sustainable production system, such as the 'Circular Economy.' Drawing on the Dubin (1978) methodology-a paradigm for building models through deduction-we design a sustainable model, which shows family businesses' responses to changes in the environment. It explains the reasons why family firms transition to the Circular Economy, based on the theory of Socio-Emotional Wealth (SEW). We check the model through the case study of the food retail leader in the Spanish market-Mercadona-which applies policies about energy, resources and waste to become a Circular Economy business model. Because of the strong family character of Mercadona, this case can be useful for the decision-making of other family businesses.
