In an increasingly urbanized world, construction industry is called upon to serve the needs of human society, such as environmental protection and safety in terms of infrastructure. In this context, a sustainable and ethical development means a close connection between buildings and environment. This connection can be achieved through, for example, the concept of ecological concrete or green concrete, as it is often called. The conventional process of obtaining cement and mineral aggregates from the concrete composition generates pollution, especially through (...) greenhouse gas emissions. Also, one should not ignore the fact that extraction of the raw materials affects the habitats of the sites and of the neighboring areas. When construction materials are questioned, the ethical issues lay not in the means of expression, but mainly in the means of production. More to the point, the present contribution aimed to find solutions for enhancing the adhesion of vegetal aggregates with the cement matrix, in order to obtain a material with optimal mechanical properties, which is valued as an ethical approach of building industry. Results showed that plant aggregates can be used to obtain a building material which can be improved by using partial substitution of cement by silica fume, fly ash, or by using additives and that green concrete as an environmentally friendly material offers the alternative for lower energy use and fewer CO2 emissions. Marketers must understand not only the advantages of these green materials, but also that they have an ethical commitment to provide consumers with environmentally friendly materials. (shrink)

The present study aimed at investigating the heavy metals concentrations in the soils around “Larga de Sus” abandoned mine, evaluating the potential ecological risk of heavy metal pollution and highlighting ethical aspects related to risk assessment, ecological restoration, and soil remediation. The results of the chemical analysis showed that the soil in the study area is highly polluted with heavy metals since the average concentrations of Pb, and Ni in soil exceed their corresponding threshold established by the Romanian legislation. The (...) potential ecological risk index method developed by Hakanson was used to assess the potential risk of heavy-metal pollution. The results indicated that Pb and Ni showed severe and considerable potential ecological risk, while Cr had lightly ecological risk. In this case, remediation should be focused only on Pb or on all heavy metals even if they have lightly ecological risk? A scientific management technique cannot logically prescribe which choices should be selected. The interaction between human activity and the environment is complicated and difficult to quantify and risk management cannot and should not be based simply on risk assessment results. What is needed to make the right choice of the most appropriate alternative that fits our personality, culture, religion, and desires? The moral and ethical implications of ecological restoration and soil remediation have to be incorporated within the decision-making process in order to make optimum sustainable decisions and to achieve real environmental protection.

The ongoing conflict between the economic imperative of stimulating consumption as part of the proliferation of neoliberal ideals of consumer supremacy and growing concern to increase environmental protection presents an opportunity to focus on consumption with respect to ethical behavior. Ethical concerns regarding purchasing and consumption behavior are addressed here in relation to the adoption of principles associated with temperance as applied to self-restraint in food purchase and consumption. The paper outlines theological links to the concept of temperance as applied (...) to environmental and health concerns. Employing a virtue ethics perspective, it examines people’s proactive attitudes that value the environment by adopting waste reduction behaviors. Within the context of normative ethics, it is asked: “Is temperance able to fulfill the role of a lever in consumers’ hands and thereby contribute to minimizing negative environmental impacts associated with food waste?” The research bears witness to the role that consumer behavior may play in promotion and application of temperance in daily life. Study results from a survey conducted in Romania extend the scant information on people’s food waste behavior in relation to religion, underscoring the relationship between religion, temperance-oriented behavior and environmental concerns.

The study uncovers the drama of Stei Baita (Romania), a former uranium mine, which experienced during the communism period, an intensive industrialization. This shaped the territorial pattern, cultural, economic and social relationships, with a tremendous impact on the quality of the environment which was sacrificed against a rapid of a so-called economic growth. Stei Baita is a classic example of legacy mine land and the authors aim is to capture and assess all important aspects of sustainable development within this study-case (...) of disadvantaged community living in a radon prone area. More specifically, authors introduce their responses to several questions: (1) What do we know about social, economic and environmental capital of the selected settlement?; (2) Is the legacy of a uranium mine the platform of debate for negotiating for sustainable development?; and (3) What is the role of ethics in the current context of Stei Baita? Within the framework of analysis, equity, seen as part of ethics, is valued both as the premise of the debate and mandatory requirement for human development that should target sustainability. Authors have not discussed truths, but positions on identified problems by investigating community members’ perceptions. Thus, peculiarities of this community are dealt within a thematic context (e.g., resources and environment, individual development, social system). Finally, ethics is valued as social construct built by negotiating interpretations of morally desirable situations and behaviors accepted in a particular society at a certain historical moment. This view is consistent with ethical relativism which denies the existence of a unique moral truth and which sets the understanding of Stei Baita context on the path of the “new ethics”. The “new ethics” depicts the world in nuances, allowing society to surpass obstacles to the progress of understanding. (shrink)
