A critical review on solid waste treatment using plasma pyrolysis technology

Kangana P. Bhatt et al.

Summary: Solid waste management has become a significant global concern due to the increase in per capita waste generation. Improper waste management practices have had a significant negative impact on the environment. Plasma pyrolysis technology offers an environmentally safe approach to converting solid waste into energy, producing high-quality syngas/hydrogen, and minimizing solid residue. This review examines the current status of plasma pyrolysis technology and its application in treating various types of solid waste, including hazardous waste. It also explores the compositions and uses of the resulting solid residue and syngas, as well as the design and generation sources of plasma reactors. Additionally, the cost estimation and challenges of this technology are discussed, along with recommendations to make it a viable option on a larger scale.

Luminescence of MgF2-WO3 ceramics synthesized in the flux of 1.5 MeV electron beam

Liudmila A. Lisitsyna et al.

Summary: The comparative analysis of optical properties between MgF2 single crystals and MgF2 ceramics, both non-doped and doped with tungsten trioxide, was conducted. The results showed that the synthesized ceramics had a high degree of crystallinity and a composition close to stoichiometric. The initial defectiveness of the ceramics samples consisted of WO3 complexes and F-2- type radiation defects, similar to those observed in irradiated MgF2 single crystals.

PLASMA CHEMICAL CONVERSION OF SPENT LUBRICATING MATERIALS

V. E. Messerle et al.

Summary: A thermodynamic analysis was conducted to identify the optimum parameters for plasma chemical conversion of spent lubricants. A closed-cycle scheme was proposed to integrate plasma chemical treatment, allowing for the simultaneous production of synthesis gas and isolation of precious metals with minimal environmental impact.
