There are about 260 thousand tons of waste glass fibers each year in the world. If they were re-melted and reeled off again, not only it doesn’t conform to the economic cost, but also the quality of these glass fibers is poor as they are easy to be pulled apart, which will bring more waste glass fibers. If these waste glass fibers were recycled, it will save 2 million US dollars of energy expense and 5 million US dollars of wastes cleaning fees, and reduce 70 thousand tons of CO2 and a considerable amount of NOx each year. In this plan, after recycling waste glass fiber yarns, we have proceeded with washing, surface modification, cutting, drying, and sieving to produce recycled chopped strands. Then we have compounded these strands with the nylon and tested for its effectiveness. The result shows that the physical properties of the reinforced nylon generated from recycled chopped strands have reached over 80% level of commercial products. It provides another source to the fiber reinforced materials industrial circles. Via this plan, we can not only carry out the zero wasting policy of the government, but also reduce the raw material cost of the fiber reinforced plastics industry.
