Waste incinerator residue treatment: Variability implications.

Air pollution control residues are a hazardous waste, collected when controlling the flue gas emissions created within modern energy from waste incinerators. They are inherently variable with regards to mineralogy and morphology. However, this variability is frequently neglected throughout the scientific literature concerned with their management. This work characterises residues collected from five different UK facilities and highlights the implications of their compositional variability for the performance of products resulting from a stabilisation/solidification treatment. It is demonstrated that the variability is of significance for the mineralogy and several key engineering properties of the products, and links between the properties of the residues and the behaviour of the products are shown. Residue variability should be considered when researching technical management options. Treatments are likely to require modification in order to satisfy performance envelopes for individual batches of residue

Composite MOF Foams: The Example of UiO-66/Polyurethane

Composite MOF foams were prepared using a direct synthesis of UiO-66 over a polyurethane foam template. Under optimized conditions, the composite materials maintained the macrostructure and flexibility of the polyurethane foam, and exhibited the microporosity, high surface area, and adsorption properties of the UiO-66. The composite MOF foam has hierarchical porosity and high adsorption capacity for benzene and n-hexane, maintaining more than 70% of the adsorption capacity of the UiO-66
