derived fuel (RDF) in WTE co-incineration plants (Sarc and Lorber, 2013). RDF has been broadly applied in cement kilns or co-firing with coal in power plants (Chol et al., 2018). Recent years have seen an increasing number of RDF power plants in Thailand. RDF is used in the mechanical process of MSW treatment, resulting in a high heating

Bull, noticing that kilns' appetite for fuel was denuding the Indian landscape of trees, designed the BTK to take advantage of waste heat from newly fired bricks and fuel combustion. 13 The kiln consists of a circular or oval trench in which green bricks are stacked in a lattice pattern. Workers create a continuous firing zone—they shift ...

Plastic waste has good calorific value, ranging between 15 and 45 GJ/tonne, according to the kind of plastic and can be used as solid-recovered fuel [12]. Plastic waste present in landfills or dumpsites is a heterogeneous mixture of different forms of plastic, which is mainly composed of single-use plastic.

Currently, there are three types of plastic waste recycling: mechanical recycling, incineration, and chemical recycling. Mechanical recycling is the most widely used recycling option, and it involves mechanically grinding or compounding plastic waste for re-use in similar products. However, this process will result in poorer plastic quality ...
