Raising Awareness for Sustainable Development Goals Through Hands-On Experiments

With the aim of protecting our planet, the United Nations defined 17 Sustainable Development Goals (SDG), which requires the involvement of all countries to make an endeavour to achieve better living conditions. In this regard, stakeholders such as governments, regional and international organizations, and civil society need to work together to make efforts to meet these objectives. In addition, Higher Educatio...

Wastewater Electrolysis for Hydrogen Production

Due to its highest gravimetric energy density, H2 has been regarded as the preferred clean-energy carrier, with potentially environmentally-friendly production through the solar-assisted WS. Since human activities generate enormous amounts of WW, H2 production from this new resource has gained attention as an emergent technology. This paper addresses the most relevant and current aspects of H2 production from W...

Cultivation of Energy Crops in Constructed Wetlands for Wastewater Treatment: A...

The need for sustainable, clean, and secure energy sources is a current issue for all nations. All kinds of vegetal biomass can be used as energy-source or as raw material for biofuel production, but some species are commonly classified as energy crops. This work evaluates the energy potential of 35 species of energy crops when produced in constructed wetlands (CW). Producing energy crops in CW is a route to li...

Physics of Sound to Raise Awareness for Sustainable Development Goals in the Co...

This paper aims to present an interdisciplinary approach intended to raise awareness for Sustainable Development Goals in the context of STEM (Science, Technology, Engineering, and Mathematics) hands-on activities targeted to elementary and secondary school. In particular, contents related to the physics of sound are used to warn about the dangers of noise pollution and its consequences for health, well-being, ...

Remote Monitoring of Energy-autonomous Constructed Wetlands

Constructed Wetlands systems (CW) are nature-based and sustainable technology for treating wastewater, contributing to the management and protection of freshwater resources. Moreover, CW can contribute to valorizing waste materials, producing reclaimed water for diverse applications, and producing plant biomass that can be material and energetically valorized. Because CW efficiency depends on several mechanisms...

Bioenergy routes for valorizing constructed wetland vegetation: An overview

Valorizing constructed wetlands vegetation into biofuels can be a way to contribute to mitigating the increasing energy demand, avoiding the use of arable land, freshwater, and fertilizers consumption, while simultaneously treating wastewater with eco-friendly technology. This work shortly overviews the main genera of wetland plants and the main routes of vegetal biomass conversion into biofuels including bioch...

Isolation, Identification, and Characterization of Phosphate-Solubilizing Bacte...

Soil microorganisms play an important role in maintaining natural ecological balance through active participation in carbon, nitrogen, sulfur, and phosphorous cycles. Phosphate-solubilizing bacteria (PSB) are of high importance in the rhizosphere, enhancing the solubilization of inorganic phosphorus complexes into soluble forms available for plant nutrition. The investigation of this species of bacteria is of m...

Valorization of solid waste in subsurface flow constructed wetlands based on re...

In this chapter, a case study is used as a basis for discussion of the contribution of constructed wetlands (CWs) to circular economy and to sustainable development. Although CWs already represent a sustainable and green technology for wastewater treatment, this study aimed to enhance CW potential to fit the circular economy paradigm. The main purpose of the study was the use of renewable materials and solid wa...
