Abstract
Paper deinking residue (DIR) is a composite waste material generated from paper deinking processes. It is currently underutilized, and its valorization represents both an environmental and economic burden for relative industries. Effective valorization of this low-value waste stream is crucial for paper recycling industries to improve their competitiveness and profitability. Pyrolysis is a promising thermochemical technology to convert biomass/wastes into value-added products. The integration of microwave irradiation as an alternative heating source allows pyrolysis processes to be carried out in a much more efficient and convenient manner. In this chapter, the thermochemical valorization of DIR through pyrolysis and potential applications of its pyrolysis products are demonstrated. Furthermore, the application of microwave-assisted pyrolysis at relatively low temperatures (< 200≥C) to exploit potential value of DIR is highlighted in a case study, which provides an example of how green and sustainable technologies could contribute to recover value from wastes and generate wealth.
