Thermal Conversion of Solid Waste Fuels
Summary
Thermal conversion of solid waste fuels encompasses a suite of high-temperature processes—incineration, gasification and pyrolysis—aimed at transforming heterogeneous waste streams into energy, syngas, biochar and inert residues. Driven by mounting municipal and industrial waste volumes, these technologies offer integrated solutions for waste management, resource recovery and greenhouse-gas mitigation. Incineration relies on excess oxygen to oxidise organic matter, yielding heat and flue gases that can be harnessed for power generation. Gasification operates under sub-stoichiometric oxygen or steam conditions to produce a combustible synthesis gas rich in carbon monoxide and hydrogen. Pyrolysis, conducted in the absence of oxygen, decomposes biomass and polymeric wastes into liquid tars, non-condensable gases and a solid carbonaceous char. Key challenges include feedstock variability, emissions control, reactor design and process optimisation to maximise energy efficiency while minimising pollutant release. Advances in feedstock pretreatment and catalyst development have enhanced conversion rates and selectivity, enabling co-processing of mixed municipal solids, agricultural residues and polymeric wastes. Globally, thermal conversion plants have been deployed to reduce landfill dependence, recover energy in urban centres and valorise industrial by-products. Ongoing research integrates numerical simulation, advanced monitoring and hybrid process schemes to deliver modular, low-emission systems that align with circular-economy objectives and net-zero targets.
