Developed under the SMEP-funded GIVO-Warwick project, lead by the University of Warwick, the below study is the first of its kind assessing Modified Basalt Fibre (MBF) bio-nests treating wastewater with exposure to nano plastic.

Biological nests made of MBF serve as effective carriers for enhancing wastewater treatment. However, little is known about their performance when exposed to nano-plastics. This study investigates the decontamination efficiency and microbial functionality of four types of MBF and tradition Basalt Fibres (BF) as carriers in contact oxidation reactors. 

Compared to BF, MBF demonstrated superior growth effects and biocompatibility within the bio-nest. The findings underscore the structural stability enhancement of Mn-MBF and Ca-MBF bio-nests in contact oxidation reactors, demonstrating their resilience against nano-plastic pollution.
