20.500.12556/DiRROS-18065 Bio-solution for global sand crisis and sustainable organic agriculture in desert states Sand is an important component of many everyday items, and currently sand is the second most extracted resource on earth after water, but it is not sustainable: we are running out of sand! The black market is booming, and the sand mafia is mining sand at any price. Desert sand is unusable, even Dubai must import it. The smooth surface and iron impurities prevent its industrial use. In this study, bacteria in the bioleaching test attacked the surface of the mineral grains and dissolved impurities including iron through organic acids. Furthermore, the liquid residue containing dissolved iron, organic acids and bacteria stimulated the growth plant what can be a valuable biofertilizer and biostimulant for organic agriculture. Desert states have fertility problems. Despite this, Qatar, for example, is aiming for self-sufficiency in vegetables “in five years”. Results showed that bioleaching combined with magnetic separation resulted in iron removal of 73.23%. The sand after treatment can be suitable to produce clear flat glass, coloured container glass, insulating glass fibres or ceramics. The integrated technology based ecological study revealed overall as utilization potential of the desert sand and the liquid residue could support glass and food production in desert states. materials sand bioleaching sustainable organic agriculture desert states materiali pesek bioluženje trajnostno ekološko kmetijstvo puščavske države true false true Taylor & Francis, imprint CRC Press Angleški jezik Slovenski jezik © 2022 Copyright the Author(s) Neznano 2024-01-31 12:26:11 2024-01-31 12:30:27 2024-02-01 03:40:50 0000-00-00 00:00:00 2022 0 0 Str. 93-101 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-03-03 620.1/.2 10.1201/9781003259954-10 101861635 101848579 https://library.oapen.org/handle/20.500.12657/53229 1 8adac540-c02b-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24511 RAZ_Styriakova_Darina_2022.pdf RAZ_Styriakova_Darina_2022.pdf 1 B5CF554948E077699B729315BC153EA4 2cfaea84e59e1d9787fbb92b405571e99e4fbd3e60de78cbc26cf3fe293318ed 1deb50db-c02c-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24513 http://dx.doi.org/10.1201/9781003259954-10 0 fad3a0f3-c02b-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24512 Zavod za gradbeništvo Slovenije 0 0 0
