  4. 2. The Story of Phosphorus : Sustainability implications of global phosphorus scarcity for food security

    Author : Dana Cordell; Stuart White; Jan-Olof Drangert; Julie Wilk; Johan Rockström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; global phosphorus scarcity; peak phosphorus; global food security; sustainable resource use; food production and consumption system; transdisciplinary; systems thinking; global fosforbrist; peak fosfor; global matsäkerhet; hållbar resursanvändning; system för produktion och konsumtion av mat; transdisciplinaritet; systemtänkande; Water in nature and society; Vatten i natur och samhälle;

    Abstract : The story of phosphorus began with the search for the philosopher’s stone, and centuries later the critical role of phosphorus in soil fertility and crop growth was highlighted. Eventually, phosphorus was implicated in the global environmental challenge of eutrophication. READ MORE

  5. 3. Ash transformation in thermochemical conversion of different biomass resources with special focus on phosphorus

    Author : Ali Hedayati; Marcus Öhman; Christoffer Boman; Kentaro Umeki; Anita Pettersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural biomass; forest residues; sewage sludge; ash transformation; release; potassium; phosphorus; combustion; gasification; bio charcoal; phosphorus recovery; Energy Engineering; Energiteknik;

    Abstract : A great potential exists for increasing the use of bioenergy in thermochemical processes by utilizing agricultural biomass, forest residues, and sewage sludge that have high availability. Many of these biomass assortments have high ash contents with relatively high concentrations of ash-forming elements such as potassium (K), calcium (Ca), silicon (Si), and phosphorus (P). READ MORE

  6. 4. Studies of ash transformation processes in thermochemical co-conversion of phosphorus-rich manure and sludge with biomass residues

    Author : Gustav Häggström; Marcus Öhman; Anders Lagerkvist; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sewage sludge; agricultural residues; forest residues; ash transformation; potassium; phosphorus; combustion; gasification; phosphorus recovery; Energy Engineering; Energiteknik;

    Abstract : Efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus (P) present in manure and sewage sludge. READ MORE
