This review includes a brief overview of human impacts on the global phosphorus cycle and a survey of existing ecological engineering techniques for phosphorus recovery and recycling discussed in the literature.
Concern over poor management of these vital resources and continued efforts to enhance soil fertility and food security have stimulated interest in phosphorus recovery and recycling.
For the more detailed recording of the potential of recycling phosphorus from aquatic freshwater plants and, in particular, of aquatic macrophytes in Germany, further investigation of the surface waters (regarding the littoral area) is required.
Using such a kind of systems solves the following tasks: receiving third-generation biofuels, disposing carbon dioxide, cleaning and disinfecting the wastewater, recycling phosphorus compounds, using solar radiation for heating.
Therefore, developing methods for removing and recycling phosphorus from wastewater would address both of these problems.
