dc.description.abstractABSTRACT: The focus of the research was to evaluate the use of lignin from different sources as an agent for the removal of diverse types of microplastics when present in wastewater. Organosolv lignin was obtained from three different sources (Miscanthus sp., pine bark and solid anaerobic digestates from Organic Fraction of Municipal Solid Wastes) by an ethanol-based organosolv treatment carried out in a pressurized stirred-tank reactor. The lignins obtained were evaluated as an adsorbent for diverse types of microplastics: High-density polyethylene (HDPE), Polystyrene (PS), Expanded Polystyrene (EPS), and Polypropylene (PP). All lignins used had the capacity to capture plastic particles from all plastic types, but a differential absorbance potential was found both for plastic types and lignin samples. EPS was the least adsorb type for all lignin sources, with the remaining plastics presenting equivalent results. Pine bark lignin was the best adsorbent among the tested feedstocks, always presenting the best performance for all plastic types. The direct utilization of organosolv hydrolysates, avoiding lignin recovery presented a similar behaviour. These results open the possibility to develop new natural, plant-based, adsorbents for microplastic removal from contaminated wastewater.pt_PT
dc.description.abstractREZUMAT: Scopul cercetării a fost evaluarea utilizării ligninei din diferite surse ca agent pentru îndepărtarea diferitelor tipuri de microplastic atunci când sunt prezente în apele uzate. Lignina a fost obținută prin metoda organosolv din trei surse diferite (Miscanthus sp., scoarță de pin și digestat anaerob solid din fracțiunea organică a deșeurilor solide municipale) printr-un tratament pe bază de etanol, realizat într-un reactor sub presiune cu agitare. Lignina obținută a fost evaluată ca adsorbant pentru diverse tipuri de microplastic: polietilenă de înaltă densitate (HDPE), polistiren (PS), polistiren expandat (EPS) și polipropilenă (PP). Toate tipurile de lignină au avut capacitatea de a capta particule de plastic din toate tipurile de plastic, dar a fost observant un potențial de absorbție diferențiat atât pentru tipurile de plastic, cât și pentru mostrele de lignină. EPS a fost tipul cel mai puțin captat pentru toate sursele de lignină, materialele plastice rămase prezentând rezultate echivalente. Lignina din scoarța de pin a fost cel mai bun adsorbant dintre materiile prime testate, prezentând cea mai bună performanță pentru toate tipurile de plastic. Utilizarea directă a hidrolizatelor de organosolv, evitând recuperarea ligninei a prezentat un comportament similar. Aceste rezultate deschid posibilitatea de a dezvolta noi absorbanți naturali, pe bază de plante, pentru îndepărtarea microplasticului din apele uzate contaminate.pt_PT
