DESCTIPTION

Technological feasibility and economic benefits limit the degree of which companies are willing to reuse defective products and scrap materials. In this project, working with Transway inc, REnato lab aim to provide our client a solution grounded by principles of circular design. By utilizing the color coding of polyamide (PA) and thermoplastic polyurethane (TPU) components of our client’s product, we aim to maximize the purity of material recovery, allowing easy reintegration into the supply chain and reducing overheads.

Intention

Maximize efficiency parameters for crushing and sorting of two-color injection molding products

Assess the suitability of PA properties as a reused material

Evaluate the benefits of developing a two-color injection molding product recycling chain

 

Service


Current state of product:

This type of product uses black PA and colored TPU for injection molding. The resulting composite material waste accounts for the largest proportion in mass, but its lower price point underlies its need for interventions.

PA reuse modeL:

By adjusting the proportion of PA regrind for injection molding, we hope to find the perfect material ratio that maximizes recovery efficiency from color sorting while maintaining product qualities and reducing the cost of raw materials.
