Fabrication of biodegradable chicken feathers into ecofriendly-functionalized biomaterials: characterization and bio-assessment study

Abstract

This study aims to investigate novel applications for chicken feather waste hydrolysate through a green, sustainable process. Accordingly, an enzymatically degraded chicken feather (EDCFs) product was used as a dual carbon and nitrogen source in the production medium of bacterial cellulose (BC). The yield maximization was attained through applying experimental designs where the optimal level of each significant variable was recorded and the yield rose 2 times. The produced BC was successfully characterized by FT-IR, XRD and SEM. On the other hand, sludge from EDCFs was used as a paper coating agent. The mechanical features of the coated papers were evaluated by bulk densities, maximum load, breaking length, tensile index, Young’s modulus, work to break and coating layer. The results showed a decrease in tensile index and an increase in elongation at break. These indicate more flexibility of the coated paper. The coated paper exhibits higher resistance to water vapor permeability and remarkable oil resistance compared to the uncoated one. Furthermore, the effectiveness of sludge residue in removing heavy metals was evaluated, and the sorption capacities were ordered as Cu ++ > Fe ++ > Cr ++ > Co ++ with high affinity (3.29 mg/g) toward Cu ++ and low (0.42 mg/g) towards Co ++ in the tested metal solution.

Uso De Plumas De Pollo Como Medio Filtrante Para La Remoción De Metales Pesados en Aguas Ácidas

“…La adsorción de metales pesados ha emergido como una estrategia rentable, sencilla y confiable en diversas aplicaciones comerciales. La eliminación de estos metales no solo constituye una solución eficaz para reducir costos, sino que también promueve prácticas sostenibles y eco amigables generando beneficios, tanto en el ámbito económico como en el ambiental (Goda et al, 2022).…”

Improvement of Bacillus subtilis PI agarase production, hydrolysate scavenging capability assessment, and saccharification of algal biomass for green ethanol generation

“…The design matrix with 12 trials along with two core trials to identify human error, the response that was observed (agarase production), and three levels for the chosen parameters, denoted as high (+ 1), medium (0), and low (− 1) all are displayed in Table 3 . The model was implemented using the coefficient outcomes of each factor 48 , 49 .…”

Recycling of chicken feathers

“…The global production of chicken feathers has been estimated to reach millions of tons annually. [ 8 ] Traditional treatment approaches fail to enable the high‐value utilization of chicken feather waste, with only a small fraction of feathers currently being recycled. [ 9 ] For instance, some feathers are employed in the production of down jackets owing to their exceptional thermal insulation properties, while others are converted into feather meal or fertilizers for animal husbandry and agriculture owing to their rich protein content.…”
