  1. 1. Phosphorus recovery for fertilisers from dairy wastewater – Sustainability assessment at early stages of technology development

    Författare :Marta Behjat; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impacts; LCA; screening; phosphorus recovery; sustainability; indicator; meta-analysis; wastewater treatment; dairy wastewater;

    Sammanfattning : A reduction in the availability of phosphate rock resources for fertiliser production coincides with an increase in phosphorus-rich dairy wastewater in Europe. This confluence of events has led to the development of technologies for phosphorus recovery from dairy wastewater and the use of the products as fertilisers in agriculture. LÄS MER
