The goal of this article is to present the problem of sustainable, self-sufficient and off-the-grid buildings in cold climates. Living off-the-grid is a part of the drive for sustainable living, in accordance with the principles of sustainable development. Buildings that are self-sufficient and which are not a part of the traditional power generation infrastructure have, on average, a much smaller environmental footprint and produce much less carbon dioxide, relying on renewable energy sources and environmentally ...

Removal of potentially harmful As compounds by adsorption onto biosorbents is a cost-effective alternative to the conventional treatment methods. Peatlands can accumulate arsenic originating from both natural and anthropogenic sources [1-3]. Wetland soils and sediments are subject to frequent changes in redox conditions, driven by fluctuations in the water table and shifts in biological activity. Under oxic conditions, natural organic matter (NOM) promotes arsenic release from metal-(hydr)oxides, thereby enhancing...
