This paper introduces three typical biogas systems which regard anaerobic fermentation of human and animal “wastes” as a key technology, and which link sanitation and biogas production with agricultural use of digested effluents.

This study has evaluated eleven precipitated phosphates as sources of phosphorus (P) or plant growth by comparing their effectiveness with that of monocalcium phosphate (MCP), a source of water-soluble P that is generally considered to be fully plant available. The precipitated phosphates comprised Struvites recovered from wastewater discharges (mainly magnesium ammonium phosphate), laboratory synthesised Struvites, a synthetic iron phosphate and a recovered calcium phosphate. The grass dry-matter yields and P offtakes given by the synthetic and recovered Struvites were not significantly different statistically either between themselves or to MCP applied at the same rate. On this basis these Struvites could be used to recycle P to similar soils and the effect of the P on crop yield should be similar to that of MCP.

In 1991, the first subsurface flow constructed wetland for treatment of domestic wastewater was built in Norway. Today, this method is rapidly becoming a popular method for wastewater treatment in rural Norway. This is due to excellent performance even during winter and low maintenance. The systems can be constructed regardless of site conditions.
