Yes, the scraps are minimal for the energy saved using the GO.....I use mine as often as I can....as far as scraps, threads for bird nests..heard the same about the danger of dampness,but also strangulation/ choking from the thread bits....I personally save mine in a pillow case?..old or purchased from local goodwill or make one from a WHY? Piece of fabric, when full sew shut and take a ride to local vets office......
