In times when raw materials are running low and the demand for consumer goods is increasing, the topic of recycling becomes more and more important. Products made out of wood, metal, paper, plastic, rubber and other materials are already recycled on a large scale and made available again for the processing industries as secondary raw material. However, the almost exclusively mechanical recycling processes hold a high risk of fire. Sparks, glowing embers or particles can be generated which can cause serious fire and explosions. A GreCon spark detection and extinguishment system significantly increases the safety and protection of the production facilities. It detects sparks in time and automatically extinguishes them – and has done so successfully for more than 40 years.
