Insulation materials based on recycled feather waste: a review

Abstract

Recently, the world has been moving towards reusing wastes in many industrial applications, such as buildings and automotive, to eliminate the environmental pollution impact due to increasing waste worldwide. Besides, waste reuse also leads to cost savings and improves sustainability. Therefore, this short review aims to present and discuss the recently used methods of utilizing feather waste as sustainable and renewable insulation instead of traditional petroleum-derived materials. The father's low thermal conductivity ranges from 0.024 W/(m. K) to 0.034 W/(m. K), and it's chemical composition and microstructure effectively trap air and produce a good barrier. So, feather waste fibers can be used as an effective thermal and acoustic insulation material with the same or better performance than commercially available products. However, several significant barriers and limitations associated with the manufacturing process of feathers insulations were identified in this review. These limitations make the commercial development of insulation materials based on feather waste a challenge. They need to be appropriately addressed to realize the potential of feather waste as a reliable insulation material.
