Paper for recycling (PfR) goes through various unit operations before foreign bodies and impurities such as trash, rivets, sand, printing ink, dirt and stickies are removed. This can altogether result in 15%‒25% rejection of input. From all reject fractions generated, fine screen rejects are perhaps the most interesting as their long fiber content is high and they are usually reasonably pure from foreign bodies. However, the high content of macro stickies and dirt speck prevents the utilization of this fraction.
