In order to explore the methods of recycling waste paper, reduce environment pollution, and develop a circular economy, the application of waste corrugated paper to the strengthening of polylactic acid (PLA) was studied. Plant fiber from waste corrugated paper (WCPF) was used to prepare WCPF/PLA composite via co-extrusion. The WCPF was extracted from the waste corrugated paper by beating in a Valli beating machine and grinding in a disc grinder. KH-550 coupling agent was used to modify the surface of WCPF to improve the interface adhesive strength between the WCPF and PLA matrix. The effects of the contents of WCPF and KH-550 coupling agent on the mechanical properties, microstructure, crystallization properties, and thermostability of the WCPF/PLA composite were studied. The results show that the WCPF can be well separated from each other. The WCPF can be uniformly dispersed in the PLA matrix through a co-extrusion process. WCPF can increase the mechanical strength and deformation resistance ability of WCPF/PLA composite, and KH-550 coupling agent can further improve that of the WCPF/PLA composite. This study is of obvious significance to the recycling of waste paper and the development of a circular economy.

Mesoporous activated carbon was generated from the spent disposable papercups and explored as an air‐breathing electrode for rechargeable Li‐air battery. The carbon was synthesized through chemical activation using KOH at different temperatures 400°C, 600°C, and 800°C. The crystal structure and mesoporous nature of the activated carbon were characterized by X‐ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FT‐IR), scanning electron microscope (SEM) techniques, and the elemental composition was analyzed by X‐ray photoelectron spectroscopy (XPS). The activated carbon obtained at 800°C had the surface area of 752 m2 g−1. The oxygen reduction reaction/oxygen evolution reaction (ORR/OER) kinetics conducted in rotating ring disk electrode (RRDE) under Ar and O2 atmosphere with 0.1 M KOH confirmed that the carbon electrode obtained at 800°C achieved inherent catalyst activity. The high surface area, effective O2 adsorption and the more active sites provided on the surface of the C800 electrode lead to high ORR and OER catalytic activity. A CR‐2032 coin cell was fabricated to demonstrate Li‐air battery using the C800 electrocatalyst as an air‐breathing electrode that showed stable OCV and the high discharge capacity of 1035 mAh g−1 at a current density of 50 Ag−1. The fabricated cell was applied for practical implementation by glowing 2.8 V commercial LED bulb for about 18 hours continuously.
