The processing of PFAS to convert them into safer substances comprises introducing gaseous or vapour phase PFAS into a treatment zone where microwave radiation of predetermined frequency and power level creates a plasma which at least partially dissociates the PFAS. There is also a system for remediating particulate solids, particularly soil, contaminated with PFAS, the method including directing microwave radiation to a body of particulate solids in the closed vessel so as to promote vaporization of PFAS which are then treated by exposure to the microwave produced plasma. Continuous and batch processing apparatus are disclosed. A preheating stage can dry the particulate solids to a pre-determined moisture content, and then a higher energy microwave heating promotes vaporization of PFAS. A partial vacuum created where particulate solids heated by the microwave radiation are yielding up PFAS promotes the vaporization of PFAS. Alternating cycles of high pressure during microwave irradiation and low pressure or partial vacuum can avoid plasma generation in the heating stage while optimizing vaporization of PFAS from the particulate solids.

Embodiments provide methods of disassembling an apparel product. The methods include exposing an adhesive of the apparel product to heat or electromagnetic energy. The adhesive is disposed at least partially disposed between a major component and a minor component of the apparel product. The adhesive includes a shape memory material. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.

Present invention relates to a non-combustion machine or system for waste destruction or decomposition and exhaust clean and non-harm fill gas to atmosphere. The present invention uses plasma heat generated by the exothermic reaction taking place between the organic substances of the solid waste and ionised air contained in the solid waste machine. After this reaction, generated flue gas is filtered; cleaned and then exhausted to make the atmosphere healthier to the lives.
