Apstrakt
Sirovi fosfat se koristi kao sirovina za proizvodnju đubriva na bazi fosfora, a nedostatak njegove ponude mogao bi negativno uticati na globalno snabdevanje hranom. Kako je brzina kojom se eksploatišu ležišta fosfatne stene veća od brzine formiranja, sirovi fosfat se smatra neobnovljivim resursom. Evropska komisija je klasifikovala ovu sirovinu kao kritičnu sa aspekta procenjenih zaliha. Godinama unazad istražuju se novi resursi koji mogu biti zamena za fosfatnu stenu u proizvodnji đubriva i drugih supstanci koje sadrže fosfor. Kao alternativa javila se mogućnost primene pepela kanalizacionog mulja koji je bogat fosforom. Elixir Group kao jedan od regionalnih lidera u oblasti hemijske industrije, proizvodnji kompleksnih mineralnih đubriva, kao i ostalim segmentima agrobiznisa teži poslovanju po principima cirkularne ekonomije i hemije, te ostvaruje osnovnu misiju ovih principa - proizvodnja uz stvaranje nula otpada ima u planu izgradnju energane na otpad na lokaciji Elixir Prahovo koja će spaljivati i kanalizacioni mulj na terioriji Republike Srbije. Zbog visokog sadržaja P2O5 kanalizacioni mulj je obećavajuća alternativna sirovina, a kako je planirano da se u Republici Srbiji do 2041. godine izgradi preko 300 postrojenja za prečišćavanje otpadnih komunalnih voda, projekcije su da će ga biti generisano oko 135.000 t/god.
