“…9b, it can be seen that with the increase of discharge power, the metal fixing efficiencies of four target heavy metals all show a trend of a first increase and then a decrease. It has been confirmed that the input power of the plasma has a great influence on the temperature field distribution of the reactor [39][40][41]. The temperature plays a decisive role in the volatilization of heavy metals [42,43] because the saturated vapor pressure is closely related to the temperature.…”

Soil pollution (heavy metals and organic matter) is becoming more and more serious, phytoremediation has rapidly become a highly important method to deal with this problem. Therefore, the treatment and disposal of hyperaccumulators have been a topic of concern. In this paper, carambola leaves are selected as feedstock considering that carambola is a potential hyperaccumulator. A series of tests were performed to discuss 6 main influencing factors on total gas yield and metal fixing using a non-thermal arc plasma setup, to investigate the feasibility of plasma treatment of hyperaccumulator and provide a new method to utilize the harvested hyperaccumulator. The maximum total gas yield reached approximately 85% at an airflow rate of 3 L/min, the processing time of 7 min, discharge power of 29.95 W with the addition of water (water: sample = 1:1). A reducing or inert carrier gas or the addition of some specific inorganic additives at optimal conditions were in favor of increasing metal fixing efficiency. However, the effects of these factors usually have two sides, and some factors may have conflicting effects between gas yield and metal fixing, and. It is necessary to optimize these factors for achieving the desired goal. The obtained solid products exhibit the potential to fix metals and act as activated carbon.

“…The relevant reactions of hydrocarbons and tars are as follows: Gasification generally occurs in the presence of partial oxygen or other oxidants at a higher temperature. According to previous studies, the gasification of solid waste includes pyrolysis, combustion, and gasification stages. , The basic sludge gasification process includes the following simplified chemical conversion equations: ,− Owing to the existence of the oxidant, the oxidation reactions are given as follows: The oxidation reactions are irreversible, while other gasification reactions mentioned above reach chemical equilibrium states between the reactants . Mountouris et al , have used the Gasifeq thermodynamic equilibrium model to predict the products and optimize the process parameters in the plasma gasification of solid waste.…”

“…When modifiers, such as ZnO and the like, increase in the product, the packed structure will be damaged and decreased; thus, the immobilization quality suffers . For the case of insufficient SiO 2 , the crystalline solid residue appears with a lot of void spaces . Sufficient SO 2 is beneficial for vitrification, but it may be problematic for total organic carbon (TOC) reduction. , As a consequence, the addition of the SO 2 content is only applied to the sludge solidification processes, which work in an inert atmosphere and do not aim to obtain fuel gas.…”

Thermal plasma treatment of sludge has a significant benefit in converting hazardous waste into renewable combustible gas and inert solid product, which is a workable solution for energy and material recovery. The advantages of this approach also lie in its flexibility, smaller installation, greater compactness, fewer contaminant emissions, and minimization of mass and volume. The present review focuses on various thermal plasma processes for sludge treatment and co-processing. The review starts with fundamental aspects of plasma and mechanisms of thermal plasma sludge treatment and then four basic thermal plasma systems used in previous studies. Five main thermal plasma conversion processes of sludge are classified and discussed, namely, plasma combustion, plasma pyrolysis and vitrification, plasma gasification and vitrification, plasma co-processing, and pre-processing combined with thermal plasma unit. Specifically, key parameters influencing thermal plasma treatment of sludge are distinguished and discussed as well as energy and material recovery. On these bases, the challenges and future research perspectives are addressed.
