Wastewater treatment plants play a crucial role in water security and sanitation, ensuring ecosystems balance and avoiding significant negative effects on humans and environment. However, they determine also negative pressures, including greenhouse gas and odourous emissions, which should be minimized to mitigate climate changes besides avoiding complaints. The research has been focused on the validation… Continue reading Carbon neutrality in wastewater treatment plants: An integrated biotechnological-based solution for nutrients recovery, odour abatement and CO2 conversion in alternative energy drivers
This paper presents and discusses the life cycle assessment (LCA) of CO2 capture and of microalgae biomass production in an advanced membrane photobioreactor (mPBR) system for climate change mitigation and the generation of renewable energy carriers. The study aims to evaluate environment-relevant aspects and propose alternative solutions for optimization of the environmental sustainability of the biologically… Continue reading Advanced membrane photobioreactors in algal CO2 biofixation and valuable biomass production: Integrative life cycle assessment and sustainability analysis
Potato is the most popular non-grain food crop in the world, known for its high yield, water efficiency and nutritional value and consequently it can play a vital role in food security. Yet, the examination of the environmental impact associated with potato production represents a gap in the field of agricultural production. The purpose of… Continue reading Life cycle assessment of potato production in insular communities under subtropical climatic conditions
Hydrogen sulphide (H2S) removal from biogas is of high relevance as it damages combustion engines used for heat and power generation and causes adverse public health and environmental effects. Biological processes have been reported as a cost-effective and promising approach to desulfurize biogas. This review presents a detailed description of the biochemical foundations of the metabolic apparatus of H2S oxidizing… Continue reading Biological desulfurization of biogas: A comprehensive review on sulfide microbial metabolism and treatment biotechnologies
In the developed world, individuals spend most of their time indoors. Poor Indoor Air Quality (IAQ) has a wide range of effects on human health. The burden of disease associated with indoor air accounts for millions of premature deaths related to exposure to Indoor Air Pollutants (IAPs). Among them, CO2 is the most common one,… Continue reading CO2 in indoor environments: From environmental and health risk to potential renewable carbon source
