Mechanical Properties of a Recycled Post-Consumer Product with Complex Construction

摘要

Many consumer products have a complex construction with multiple types of materials. This makes it difficult to recycle the products if the materials are not easily separated. A mixed recycling study was conducted for a particular multi-material product to determine the degree of material segregation required to obtain a recycled feedstock with useful properties. Toothbrushes were selected as the product for this study. These were collected from a commercial take-back program and were separated by material. Different formulations were compounded with virgin material at varying percentages and molded into ASTM test specimens for mechanical property testing.
