Environmental Sanity by Recycling of Waste Polypropylene Products and Waste Coir Fibre on the Mechanical Properties as Compared to Virgin Polypropylene: A Case Study of Kaduna Polytechnic Tudun Wada
Abstract
A study of the effects of waste coir and waste polypropylene on the mechanical properties of virgin polypropylene was investigated. The coir fibres (filler) were treated with NaOH to improve properties and enhance better adhesion between matrix (PP) and filler (coir fibre) before compounding it with waste PP which was washed and crushed. Virgin PP was obtained and blended with the waste PP to determine best ratio blends. The filler was weighed and combined with waste PP into a 100mm x 100 mm x 3mm composite. Mechanical tests such as tensile, flexural, impact and hardness Shore D were carried out to determine best possible blend ratios and end uses
