The Application of Sheep Wool in the Building Industry and in the Removal of Pollutants from the Environment

The study investigates the genetic architecture of fibre diameter (FD) and staple length (SL) in Middle Anatolian Merino sheep using multi-locus genome-wide association study (GWAS) approaches. Heritability and variability analyses revealed contrasting patterns: FD showed moderate heritability (h² = 0.461) with low variability (CV = 7.570%), while SL exhibited low heritability (h² = 0.191) but high variability (CV = 24.437%). Genetic correlations indicated moderate positive relationships between FD and certain growth traits (rG = 0.385–0.455, p < 0.001), whereas SL showed weak, non-significant correlations with these traits. The correlation between FD and SL was also weak and non-significant (rG = -0.043, p = 0.383). Using four multi-locus GWAS methods (mrMLM, FASTmrMLM, FASTmrEMMA, and ISIS EM-BLASSO), which can detect polygenic effects on complex traits like wool quality, 18 SNPs for FD (7 co-detected) and 14 SNPs for SL (5 co-detected) were identified across multiple chromosomes. Post-hoc power analysis demonstrated strong statistical power for both traits (FD: 0.95, SL: 0.91). These results could guide future breeding strategies aimed at optimising both wool quality and growth performance. Further research is needed to validate these findings in other populations and to explore the biological relevance of the identified genomic regions.

In this current research, various amino acids (lysine, betaine, and cysteine) and peptides (oxidised or reduced glutathione) were considered as potential environmentally friendly alternatives to wool bleaching. A greener methodology was also applied to dyeing. Different agro-wastes (red cabbage, peppercorns, and red and yellow onion peels) served as raw pigment materials. The process’s efficiency was characterised by the whiteness degree, colour strength, and fastness to accelerated washing and perspiration. A higher whiteness index value was observed in the cysteine-based formulations. The onion peel exhibited significant tinctorial properties due to the presence of some natural mordants. All the proposed treatments were designed with a primary focus on environmental sustainability. These treatments offer a sustainable and environmentally friendly alternative to traditional bleaching and dyeing methods for wool. They reduce costs and energy consumption while creating added value by valorising waste.
