AbstractSafe water is fundamental for positive health and well-being. Much of the ill-health in society, especially in the developing countries, can be attributed to lack of harmless water. Each country elaborates its own drinking water standards based on healthbased targets.To ensure reliable consistent water-treatment and supply, drinking water standards have been prescribed both for drinking water supply and packaged/bottled water. Different countries prescribe standards that vary significant...

The need for ensuring safety of energy supply, as well as the tendency to reduce greenhouse gas emissions has led to greater use of energy efficient technologies and renewable energy sources. Cogeneration (combined production of heat and electricity) is one of high-efficiency technologies, because the losses of primary energy are less than losses from the separate generation of heat and power. Consequently, in 27 EU member-states 70% of the district heating is based on cogeneration plants. Us...

The goal 12 of the 2030 Agenda for Sustainable Development takes into consideration the responsible consumption and production in the perspective of circular economy. The agri-food sector is more actively involved in these initiatives, because it offers the possibility to exploit waste and by-products, by adopting suitable biotechnologies. Such processes can be carried out either under aerobic conditions, for the production of compost, or anaerobically, for the production of biogas. In this work...
