UG-Mat MSW Combustor Ash | Recycled Materials

The data indicate that municipal solid waste combustor ash is a relatively lightweight material compared with natural sands and aggregate. The bulk specific gravities that were reported range from 1.5 to 2.2 for sand-size or fine particles and 1.9 to 2.4 for coarse particles, compared with approximately 2.6 to 2.8 for conventional aggregate materials.

Brominated dioxins and furans in a cement kiln co

Cement kiln co-processing is a promising approach for energy recovery and disposal of solid waste. However, co-processing of solid waste could increase emission of toxic and bioaccumulative POPs (Liu et al., 2015a, Pavlík et al., 2016). According to statistical data from 2012, 58% of global cement production occurs in China (Song et al., 2016
