Optimization and mechanical characterization of casein and seaweed resin with hemp reinforcement: A review

Abstract

Plastic is a versatile material used in many products, but its production with petroleum-based materials has harmful environmental consequences. To address this issue, sustainable and biodegradable alternatives like hemp plastic are needed. Hemp plastic is made solely from hemp plants, which absorb four times more atmospheric carbon dioxide than other plants, making it an ideal solution. Additionally, hemp fiber is more durable than the standard fiber used in conventional plastic production. Casein, a naturally occurring protein in milk, can also be used to create biodegradable polymers for small items. Seaweed produces polysaccharides that can be used as a biomaterial or binding agent for creating bioplastics. In this project, hemp composites reinforced with casein and seaweed are created and characterized to evaluate their mechanical and chemical properties. These sustainable and biodegradable materials can replace petroleum-based plastics, minimizing their negative environmental impact.
