    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 method for operating at least two floating offshore wind turbines (1) is disclosed. The wind turbines (1) are operated at respective first operating positions (7), and a previous and/or a future expected wear impact on each wind turbine (1) is estimated. At least one wind turbine (1) to be relocated to a respective second operating position (9) is identified, based on the estimated wear impact. The identified wind turbines (1) are moved to respective second operating position (9) and operated there.
