Article Synopsis
- The study highlights the urgent need for sustainable organic waste management due to rising waste generation globally.
- It investigates converting organic waste from the animal feed industry into biodiesel and syngas, finding that non-catalytic transesterification is more effective than acid-catalysed methods for biodiesel production.
- The research further demonstrates that using a nickel-impregnated catalyst in pyrolysis significantly increases gas yield, enhancing the renewable energy conversion process while also addressing carbon dioxide sustainability.
To address the challenges associated with medical plastic waste and to characterize its heterogeneity, non-recyclability, and potential biohazard risks, this study explored a carbon dioxide (CO)-assisted pyrolysis process as a sustainable disposal method. Medical plastic waste typically includes polypropylene, polystyrene, and polyvinyl chloride. To experimentally evaluate the functional reactivity of CO, we employed three pyrolysis setups (one-stage, two-stage, and catalytic processes).

We present a reusable and porous skin patch (RPS patch) capable of controlling adhesion force with a thermal-pneumatic method for repetitive use as well as improving moisture permeability for long-term use without skin troubles. Previous skin patches cause skin troubles due to high adhesion force (∼30 kPa) and low moisture permeability (∼382 g/m/day), hindering them from repeatable and long-term use. We control the skin adhesion force of the RPS patch using thermopneumatic pressure generated by an embedded heater on multiple chamber arrays.
