Abstract To evaluate the environmental safety issues in the use of non-metallic recycled products from waste circuit boards, an environmental safety assessment model of recycled wood-plastic products was constructed with reference to the characteristics of recycled wood-plastic products, the environmental hazard evaluation methods, and human health risk evaluation. Also, two kinds of recycled products were collected for the evaluation test, using the model to evaluate whether there were potential risks and hazards to the environment and human health. The results showed that both the two types of recycled products might cause extreme or severe pollution to the surface water of class I. For other types of surface water, the environmental risk is low, and the recycled products should be avoided when used in the primary area of the source water. For groundwater, the pollution index of product B is greater than 1, which has a certain environmental risk; When considering dilution effects (5% of the original concentration), the pollution indexes of two recycled products for groundwater are less than 1. The hazard indexes of two kinds of recycled products are 0.03 and 0.41respectively, both of which are less than 1, with no obvious harm to human health. The evaluation model provides evaluation criteria and references for large-scale production and promotion of non-metallic material recycling. Further, it promotes the development of waste electrical and electronic products recycling and harmless technology.
