20.500.12556/RUL-172912 Možnosti ponovne uporabe kamene volne v hidroponskih sistemih Re-use options for rock wool in hydroponic systems Kamena volna je eden najpogosteje uporabljenih rastnih substratov v hidroponski pridelavi, saj je zračna in dobro zadržuje vodo, kar zagotavlja optimalno rast rastlin, kot so paradižniki, paprike, kumare, jajčevci in jagode. Uporablja se v različnih hidroponskih sistemih (pridelava na kameni volni, aeroponskih sistemih, tankoplastnem gojenju). Pridobiva se s taljenjem naravnih kamnin pri visokih temperaturah, kar pomeni, da ni biološko razgradljiva. Kljub številnim prednostim kamene volne se pojavlja pomemben okoljski problem – njeno prekomerno odlaganje v naravi. Po uporabi v hidroponiki postane odpadek, ki se pogosto ne reciklira ali ponovno uporabi, kar prispeva k onesnaževanju okolja. Čeprav kamena volna ni biološko razgradljiva, jo je mogoče reciklirati in ponovno uporabiti, vendar je ozaveščenost o tem še vedno nizka. Raziskave so pokazale, da je recikliranje kamene volne mogoče izvesti z več metodami, nekatere so že uspešno uporabljene. Eden od pristopov vključuje ločevanje kamene volne od ovoja in nato mešanje z organskimi materiali, uporaba kot zastirka ali kompostiranje, kar omogoči nastanek sterilnega rastnega substrata za sejanje. Ponovna uporaba kamene volne je možna zato, ker kljub večkratni uporabi, rastni substrat ohrani dobre fizikalne lastnosti. Takšna ponovna uporaba ohranja lastnosti rastnega substrata in bistveno ne vpliva na pridelek. Poleg recikliranja so okolju prijaznejši nadomestki kompostirana šota in lubje, ki dosegata primerljive rezultate. Rockwool is one of the most commonly used growing substrates in hydroponics due to its aeration and excellent water retention, which ensures optimal plant growth for crops such as tomatoes, peppers, cucumbers, eggplants, and strawberries. It is used in drip irrigation systems, aeroponics, and thin-layer vegetable cultivation. Rockwool is produced by melting natural rocks at high temperatures, making it non-biodegradable. Despite its many advantages, rockwool poses an environmental issue—its excessive disposal in nature. After use in hydroponics, it becomes waste that is often neither recycled nor reused, contributing to environmental pollution. Although rockwool is not biodegradable, it can be recycled and reused, but awareness of this is still low. Research has shown that rockwool recycling is possible through various methods, some of which are already successfully applied. One approach involves separating the rockwool from its wrapping, then mixing it with organic materials for use as mulch or composting, resulting in a sterile substrate suitable for seedling growth. Reusing rockwool is feasible because the substrate retains good physical properties even after multiple uses. Such reuse preserves the substrate’s growing qualities and does not significantly affect crop yield. Besides recycling, environmentally friendly alternatives such as composted peat and bark show promising results and can achieve comparable results. hidroponska pridelava kamena volna ponovna uporaba kamene volne trajnostno vrtnarstvo hydroponics rockwool roskwool reuse sustainable agriculture true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-12 07:18:25 2025-09-12 07:18:27 2025-10-28 03:34:08 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 263652 249279747 51383.pdf 51383.pdf 1 685493A5092ECAD735D1E5572DBFFCA5 7e2a430c2c215cb03e428e5a3edd8deee14b87712d65fc857e666f1e7c7a3fda c171ff9f-8f97-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=217045 Biotehniška fakulteta 0 0 0
