Yes, black fiberglass tissue can be recycled into new products. The recycling process involves shredding and grinding the material to separate the glass fibers from the resin. The fibers can then be used as a reinforcing material in composites, while the resin can be processed for other applications. However, the recycling of black fiberglass is less common due to the difficulty in separating the fibers from the dark resin, which can affect the color of new products. Despite this, advancements in recycling technology are making it more feasible to recycle black fiberglass and incorporate it into new manufacturing processes.
