Abstract: Methods and systems for recycling a printed circuit board (PCB). The printed circuit board is exposed to a swelling agent that causes an epoxy matrix of the printed circuit board to swell and disintegrate into particles. The particles of epoxy are then separated from the printed circuit board, leaving behind reinforcing fiber and metal containing components thereof. These remaining components are separated from each other and recycled separately using suitable processes. The epoxy particles are also recovered, and may be reduced to a monomer for use in synthesizing new epoxy. The swelling agent includes a carboxylic acid, preferably formic acid, as an active ingredient.

Abstract: A device may receive historical operational data for a mechanical system, such as a rotor blade of a wind turbine. The device may determine one or more quality grades for each of one or more materials of the system, e.g., the rotor blade. The one or more quality grades may be determined by using a data model to process the historical operational data. The data model may be trained using machine learning based on one or both of historical operational data for similar systems, e.g., other rotor blades, and end-of-life (EOL) testing data for the same. The device may determine a recycling recommendation based on the one or more quality grades. The recycling recommendation may include instructions relating to recycling the one or more materials. The device may deliver the recycling recommendation to another device or recipient.
