english: They extract what they can, which is mostly the metals -- circuit boards and so forth -- and they leave behind mostly what they can't recover, which is, again, mostly the plastics.
non_english: Získavajú, čo sa dá, ale predovšetkým kovy -- obvodové dosky a podobne -- a čo nevedia získať, nechávajú tak, čo je zasa prípad plastov.
