Characterization of pyrolysis products of high-ash excavated-waste and its char gasification reactivity and kinetics under a steam atmosphere

Pyrolysis of Solid Waste and Its Components in a Lab Scale Induction-Heating Reactor

“…In general, the results found in this study followed the same trends observed in RDF pyrolysis tests conducted by other researchers at 800°C (Blanco et al, 2012;Daouk et al, 2018). It is known that the sample used here presented small fractions of other fossil derived materials such as PS and rubber, known for generate high amounts of methane during their pyrolysis (Zaini et al, 2019).…”

Pyro-Oil and Wax Recovery from Reclaimed Plastic Waste in a Continuous Auger Pyrolysis Reactor

“…The increasing attention that excavation and waste reclamation received lately has led to an increase in research to valorise waste components with high ash and calorific content received from landfill sites using thermochemical conversion (TCC). Zaini et al [10] showed that refuse derived fuel (RDF) obtained from excavated waste combined with fine particles and treated using pyrolysis, produced modest oil and gas yields of 9-36 wt.% and 15-26 wt.%, respectively. This is in comparison to fresh waste samples which produces 53 and 24 wt.%, respectively, attributed to the high ash content of the landfill feedstock material.…”

Improving the efficiency of equipment and technology of waste briquetting

“…The complexity and versatility of the studied properties of recyclable materials favorably distinguish this study from alternative studies [5,[17][18][19][20][21][22] making its results more indicative and practically significant for implementation into real process flowsheets of waste processing. Thus, practical application of the information obtained about the above conclusions and the regularities of changes in technical properties of recyclables solves the identified scientific and practical problem of expanding the base of theoretical and practical data on technical parameters of various compositions of industrial and household SCW with an increase in efficiency of the process of fuel briquette manufacture.…”

“…Studies [4,5] are devoted to features of thermal recycling of carbon-containing waste, including small fractions of stored waste. Thermal recycling of waste was studied using the example of gasification and pyrolysis.…”

“…The study results have shown that the raw materials based on fine waste fractions have higher reactivity compared to other investigated mixtures due to the high content of catalytic metal elements (K, Ca, Na, Mg, and Fe) and high ash content. However, at a high scientific value [5] of the study including a detailed analysis of thermogravimetry of stored household waste, the authors practically did not take into consideration the effect of mechanical properties of the recycled material on this process efficiency.…”
