Synergistic effects of biomass and polyurethane co-pyrolysis on the yield, reactivity, and heating value of biochar at high temperatures

Valorization of disposable COVID-19 mask through the thermo-chemical process

“…Among the thermo-chemical processes, incinerating PPE is commonly practiced [18] , but it suffers from technical incompleteness in terms of air pollution controls (APCs) [19] . At the temperature regimes over the transition state, plastics are melted and volatized [20] . Radical pools created from the thermolysis of polymer, such as polyvinyl chloride (PVC), offer a favorable condition for forming toxic chemicals, such as dioxins [21] .…”

Thermal Analysis of Nigerian Oil Palm Biomass with Sachet-Water Plastic Wastes for Sustainable Production of Biofuel

“…Among the blends, the char residues decreased in mass loss with increasing portions of OPEFB with OPEFB80+SWP20 showing the highest degradation rate. These variations further suggest a synergetic effect among the biomass and plastic mixtures in that the chemical components of the plastic are acting as catalyst [38,45]. This gives new insights into the behavior of co-adding plastics in the co-pyrolysis of biomass which have not been widely discussed in previous studies.…”

Application of poly(amidoxime)/scrap facemasks in extraction of uranium from seawater: from dangerous waste to nuclear power

“…Among the above methods, incinerating is commonly used to dispose of FMs [ 16 ], which suffer from technical incompleteness in air pollution controls. The plastics in FMs melt, are volatile, and form toxic chemicals at high temperature [ 17 – 20 ]. To reduce environmental impacts of scrap FMs, the finding of new uses for FMs is a very urgent and esstential topic.…”
