Abstract

Hydroxyapatite (HAp) powder was produced by utilizing food waste bovine bones through alkaline treatment and calcination. The biodegradable coatings on paper-based food packaging that contained synthesized HAp were subsequently prepared and characterized. The slurry of 5 wt% of bovine bones synthesized HAp, 2 wt% of polyvinyl alcohol, and glycerol was coated on a grey back duplex board (GB) by dipping and spraying. The morphology, color, penetration strength, water and oil absorption, and biodegradability of the coated GB were observed. The color of the spray-coated GB was still slightly brighter (L*) than others due to its good coating ability before and after being heated at 800 W in a microwave oven for 1 minute. The penetration strength of coated GB was higher than that of noncoated GB after containing hot water. The coated GB had 8% water absorption, which was lower than that of the noncoated GB (10%), while oil absorption was nearly the same (3%). Moreover, the biodegradable properties of both coated GBs were not significantly different compared to the non-coated samples.
