For ,example,, P may be recuperated and recycled from ,wastewater,, animal metabolism, and aquatic environments in order to maintain food production yields in agriculture (Schnug and De Kok 2016). Therefore, contrarily to predictions of phosphor scarcity it seems very unlikely that phosphor may become a limiting factor in food production (Scholz et al. 2013 ; Heckenmüller et al. 2014 ).

With balanced industrial and infrastructural growth and stability in many developing countries, metal reserves are fast depleting and some of the metals are predicted to be exhausted in a few decade. Metal recovery from waste (liquid) streams, for example - acid mine drainage, is one classical option to achieve sustainable resource utilization.
