摘要：

Fiberglass-reinforced polyester wastes are at present landfilled, which is relatively expensive due to the low bulk density. Based on the experimental results reported here, alternative waste management methods may be proposed. The wastes can be densified before landfilling. This would consist of thermolyzing wastes in the presence of an oxidizing gas at 340-370 degree C. The weakened composite waste can be ground to powder to increase its bulk density by a factor of 4 or 5. The powder contains fillers and short glass fibers and the mixture could be recycled for low-grade uses. The glass fibers from the waste can be recycled. This is technically feasible, notably after liquid-solid thermolysis.
