SReS (Scholz Recycling System) is an efficient recycling-system for used surgical instruments. Through SReS, recycling of used surgical instruments becomes part of the daily routines in clinics. Compared to existing procedures, SReS saves time and reduces the costs of waste disposal while retaining the full material value. The specially designed and engineered collecting bag is lightweight, flexible, and ensures total working safety and hygiene. Because it uses language-independent icons and graphic design for the entire system, SReS is self-explanatory.
