A pervaporation apparatus and method for liquid mixture separation are disclosed. The pervaporation disclosed utilizes an interfacial-heating membrane utilizing induction heating to provide temperature differences across the membrane for driving liquid mixture separation. The pervaporation system may include an electromagnetic induction heating device that is placed close to or encapsulated in a membrane module wherein one or more membranes with surfaces containing ferromagnetic or other induction-responsive materials. The membrane surface generates localized heat owing to the presence of a ferromagnetic composition that converts electric energy from an induction source to thermal energy. The ferromagnetic composition could include, without limitation, metals, metal alloys, composite materials, nanocomposite materials, nanoparticles, meshes, and combinations thereof.

A process to transform spent cannabis biomass into activated carbon via a treatment involving a chemical activation process. The spent cannabis biomass is mixed with an activating agent and then subjected to a heat treatment. The spent cannabis biomass is heated in stages, the first to remove water and volatile components, and the second to reclaim leftover cannabinoids. During a third, higher temperature stage, the biomass is converted to activated carbon.
