Recently, polylactic acid (PLA) has replaced many plastics based on non-renewable resources. In this work, subcritical water was used for the chemical decomposition of virgin and waste PLA under different atmospheres. The main degradation product was lactic acid with very high yields. The highest yield of lactic acid was obtained under N<sub>2</sub> atmosphere, where the optimum conditions were 200 °C and 60 min and the yield was 88.96 ± 1.5 % for virgin PLA and 54.58 ± 1.3 % for waste PLA. In an air atmosphere, the maximum yields of lactic acid were obtained at 250 °C and 30 min and were slightly lower than in the N<sub>2</sub> atmosphere, i.e. 87.20 ± 0.9 % for virgin PLA and 49.29 ± 0.6 % for waste PLA. The lower yield of lactic acid from waste PLA is due to the impurities and additives in waste PLA. Other carboxylic acids were also formed in the aqueous phase, while the gas phase mainly contained CO<sub>2</sub>, N<sub>2</sub>/CO and C<sub>1</sub>-C<sub>5</sub> hydrocarbons. The hydrothermal degradation pathway was presented and the electricity costs for lab-scale PLA recycling were estimated.

However, the reversible adhesives developed so far often lack competitive adhesion strength in a bonding state. In this work, reversible epoxy adhesives based on Diels–Alder (DA) chemistry were developed and exhibited a competitive adhesion strength (e.g., 12–16 MPa of a lap shear strength) to commercial non-reversible epoxy adhesives. The reversible epoxy formulation showed superior thermal stability up to 110 °C, and transition to a debonding state in the order of 0.1 MPa at 140 °C, consequently, an on/off-type debonding behavior. The transition to a debonding state was attributed to crosslinking density control (e.g., decrease by 33 %–49 %) through the reversible DA chemistry and the proximity to the glass transition. Next, for debonding by light stimulus, photothermal refractory plasmonic titanium nitride (TiN) nanoparticles were incorporated in the reversible epoxy, which can generate the required heat for debonding upon exposure to visible light. Photothermal debonding allows for precise debonding at target areas and tunable adhesion strength by controlling the exposure area and light intensity. The DA adhesive formulations containing 0.5 wt% TiN nanoparticles presented a debonding state with zero adhesion under light exposure with intensity of 1670 mW/cm<sup>2</sup> (inducing 140 °C).
