Abstract With the increasing use of polylactic acid (PLA), more attention is turning to its post‐treatment. Current methods such as natural decomposition, composting, and incineration are limited by significant carbon dioxide emissions resource waste. Here, an efficient electrocatalytic conversion approach presented transform PLA waste into high‐value chemicals, particularly potassium acetate (AA‐K). By combining experimental theoretical calculation, a high‐performance catalyst Ni(Co)OOH developed, which exhibits current density 403 mA cm⁻ 2 at 1.40 V (vs RHE) with 96% Faraday efficiency for AA‐K in electrooxidation lactate (LA‐K, product degradation KOH). Through situ spectroscopy techniques functional theory calculations, structural regulation catalyst, reaction pathways elucidated. Further experiments demonstrate superior catalytic performance industrial‐scale tandem system. In h electrolysis, 320 g produces 232 L H₂, yielding 1200 97% purity after neutralization drying. The system demonstrates high (approaching 97%) diverse real forms, including powder, cups, fibers, cloth. This research provides scalable sustainable upcycling.
