Concepts to protect wood from factors like ultraviolet (UV) radiation, water and wood-decaying fungi with the help of fungi exist in different variants. The idea to treat wood with the help of linseed oil and the living fungus Aureobasidium pullulans originated in 1996 during an European project assessing sustainable protection systems (Sailer et al., 2010). At that time, wood impregnated with natural oils resulted surprisingly in an evenly dark colored surface. These color changes were usually associated with irregular discoloration and staining and were further investigated. It has been shown that the fungus Aureobasidium pullulans was growing on surfaces treated with linseed oil. The fact that Aureobasium pullulans reproducibly grows on water repellent linseed surfaces in many regions around the world makes it suitable for use in a wide range of applications. Research did show that Aureobasidium pullulans produces pigments and binders on its own. This contribution documents the investigation to, identify the possibilities of biological wood surface treatment with Aureobasidium. The combination of the hydrophobizing effect of linseed oil and the surface treatment with the so-called biofinish creates an aesthetically appealing dark living surface, which significantly prolongs the life of wood outdoors and reduces maintenance costs. Since the idea has been developed into an industrially applicable process (Xyhlo biofinish, 2018). Using this concept, building components e.g. façades can be protected with a biological and functional coating thereby contribution to lessen the environmental impact of buildings.

This article will discuss social, environmental, and ecological justice in education for sustainable development (ESD) and Education for Sustainable Development Goals (ESDG). The concept of sustainable development and, by extension, the ESD, places heavy emphasis on the economic and social aspects of sustainability. However, the ESD falls short of recognizing ecological justice, or recognition that nonhumans also have a right to exist and flourish. An intervention in the form of an undergraduate course titled Politics, Business, and Environment (PBE) will be discussed. As part of this course, students were asked to reflect on the three pillars of sustainable development: society, economy, and environment, linking these to the fourth concept, ecological justice or biospheric egalitarianism. Biospheric egalitarianism is characterized by the recognition of intrinsic value in the environment and is defined as concern about justice for the environment. Some of the resulting exam answers are analyzed, demonstrating students’ ability to recognize the moral and pragmatic limitations of the anthropocentric approach to justice. This analysis presents ways forward in thinking about the role of “ecological justice” as the ultimate bottom line upon which both society and economy are based. https://doi.org/10.3390/educsci10100261 LinkedIn: https://www.linkedin.com/in/helenkopnina/

Stormwaters, flowing into storm sewers, are known to significantly increase the annual pollutant loads entering urban receiving waters and this results in significant degradation of the receiving water quality. Knowledge of the characteristics of stormwater pollution enables urban planners to incorporate the most appropriate stormwater management strategies to mitigate the effects of stormwater pollution on downstream receiving waters. This requires detailed information on stormwater quality, such as pollutant types, sediment particle size distributions, and how soluble pollutants and heavy metals attach themselves to sediment particles. This study monitored stormwater pollution levels at over 150 locations throughout the Netherlands. The monitoring has been ongoing for nearly 15 years and a total of 7,652 individual events have been monitored to date. This makes the database the largest stormwater quality database in Europe. The study compared the results to those presented in contemporary international stormwater quality research literature. The study found that the pollution levels at many of the Dutch test sites did not meet the requirements of the European Water Framework Directive (WFD) and Dutch Water Quality Standards. Results of the study are presented and recommendations are made on how to improve water quality with the implementation of Sustainable Urban Drainage Systems (SUDS) devices.
