Abstract: The present disclosure provides methods for the conversion of a solution or suspension of polymers, plastics, and other carbon-containing waste materials in the presence of a metal containing catalyst into carbon nanotubes. The method includes steps of mixing the polymer and metallic catalyst in a suitable solvent and injecting the mixture into a heated zone of a chemical vapor deposition (CVD) reactor to produce carbon nanotubes (CNTs). Advantages of the present disclosure include ease of use, the potential use of a wide range of plastics that cannot be recycled or upcycled by traditional methods, and the ability to use waste hydrocarbon solvents to dissolve the plastic, or to use as a carbon source.

Abstract: Heating and processing a polymeric material is achieved using a microwave absorbing structure that defines a processing chamber to receive the polymeric material (e.g., one or more precursors to form a polymer). A microwave radiation source directs microwave radiation to the microwave absorbing structure, which absorbs the radiation and can process the material.

Abstract: High surface area 3D mesoporous carbon nanocomposites can be derived from Zn dust and PET bottle mixed waste with a high surface area. Simultaneous transformation of Zn metal into ZnO nanoparticles and PET bottle waste to porous carbon materials can be achieved by thermal treatment at preferably 600 to 800° C., and reaction times of from 15 to 60 minutes, after optionally de-aerating the reaction mixtures with N2 gas. The waste-based carbon materials can have surface areas of 650 to 725 m2/g, e.g., 684.5 m2/g and pore size distributions of 12 to 18 nm. The carbon materials may have 3D porous dense layers with a gradient pore structure, which may have enhanced photocatalytic performance for degrading, e.g., organic dyes, such as methylene blue and malachite green. Sustainable methods make ZnO-mesoporous carbon materials from waste for applications including photocatalysis, upcycling mixed waste materials.
