Disposal Center

AWG Bassum reference object 

Perfect protection throughout the entire recycling process

Part of the AWG Bassum waste disposal center is the RABA residual waste treatment system. Approximately (110,230 US tons) of residual materials are sorted and pre-treated here in a professional manner every year. When being delivered to the plant, the waste can pratically contain anything. In order to minimise the risk of fire, Rosenbauer has developed a complete stationary solution for the disposal center.

Impresses with

  • Perfect protection around the clock
  • Targeted detection and cooling
  • Reduced soaking of recycled material
  • Real early fire detection through surface temperature measurement
  • Possibility of switching from automatic to manual operation of the system
  • Emergency generator for additional operational safety

Initial Situation

Waste bears a high fire load

Waste is unpredictable from a fire protection perspective. Since one never knows exactly what is in the residual waste, hot spots or smoldering fires can form at any time.There is a risk of fire at all times!

A (preventive) fire protection system that is as efficient as it is effective and reliable is thus important, especially for the highly sensitive areas of delivery, secondary shredding, and supply.

Customized Extinguishing System

Upgrading the existing fire protection system

The existing fire protection system was upgraded with nine Rosenbauer turrets to protect the delivery hall, the shredding plant, and the supply warehouse. The 13 extinguishing areas are also equipped with a comprehensive infrared camera detection system. In the sensitive delivery area alone, two IR cameras constantly monitor the temperature. If necessary, two turrets start the cooling process preventively before a
fire breaks out. The shredder and the conveyor belt in the processing plant are also monitored in order to avoid the transfer of hot and flammable materials to other plant areas. An extinguishing turret and conveyor
belt fire protection system are used to protect the secondary shredding hall for waste fractions with a size of more than 300 mm. In the supply storage, high heat value fractions are stored until they are transported to the Blumenthal combined heat and power plant (CHP), where they are used as refuse derived fuel. Three IR cameras with six extinguishing turrets ensure optimum fire protection. They are installed at an approximate height of four meters (13 feet). The control center and the pumps for the fire protection system are compactly installed in a separate container. The use of pipe trace heating in the above-ground area ensures that the system functions even in winter when it is very cold. Pipes with a dimension of DN 150 provide the necessary extinguishing water for the turrets in all areas.

Technical details of the turret extinguishing system

  • 13 extinguishing areas – with IR camera detection
  • 9 extinguishing areas with RM 65 turrets with 2,400 l/min at 7.5 bar (630 gpm at 110 psi)
  • 4 extinguishing areas with nozzles for conveyor belt protection
  • 1 plant room with main pump, foam proportioning system and extinguishing water distributor
  • 3 sub control areas (for the delivery hall, secondary shredding and supply storage) with section valves
  • Operating time: 60 min.
  • Extinguishing water tank: 150,000 l (39,625 US gal)
  • Optimum extinguishing power due to fluorine-free foaming agent (foam proportioning rate: 1 %, class A)
  • Foaming agent tank: 2,000 l (528 US gal)
  • State-of-the-art system technology complying with VdS 2108 and VdS 3189

AWG Bassum

AWG Bassum is a 100 % subsidiary of the Diepholz administrative district and stands for environmentally friendly waste disposal and climate protection. The company's area of expertise includes the treatment
and recycling of municipal and industrial waste. Much of this takes place in the technical facilities of the Bassum waste disposal center (RABA residual waste treatment plant, composting plant, etc.).
In the residual waste treatment plant alone, the AWG team mechanically or biologically treats around 100,000 tons of residual waste for landfilling or further recycling. Some of the processed residual
waste is used to generate power in the company's own power plant (HKW Blumenthal).

The disposal area comprises the district of Diepholz in central Lower Saxony, where around 217,000 people reside. 140 waste experts look after a total of around 67,000 households and 3,000 commercial customers in 15 cities and numerous municipalities.
