Fast reaction is a must if there is a machine breakdown in the Association’s mechanical-biological treatment system. Every day 750 to 800 tonnes of residual waste are unloaded at the site east of Hannover, and every day it all needs to be worked through before the next delivery comes. The plant only has room for two days’ worth of waste. Eberhard Lütge, who is in charge of residual waste treatment at AHA, explains: “If one of the four processing lines goes down we get busy. I call Komptech, sometimes with an energetic tone of voice.”
Service technician Dennis Hahne totally understands. He’s taken care of the Association for seven years, and just switched to Komptech Mobile Machine Sales. “That’s how it has to be with volumes like theirs. If need be, we move our other appointments around so we can get them up and running immediately.” AHA works closely with the Komptech Service team. With two double lines, just the necessary maintenance means a visit about every four weeks. “Right now I’m happy. The machines are running,” says Lütge.
Through the window of the meeting room under the roof of the multi-storey hall, Lütge shows visitors how the two mechanical processing lines run from the entry doors on both sides towards each other at a right angle. Each of the lines starts with a Terminator 3400 EF, followed by big drum screens. In total four shredders and two screeners from Komptech work here on residual waste. In the adjacent organic and green waste composting line there are two stationary star screens and one each mobile drum and star screen. The screen drums in the hall were also replaced by Komptech, working through the roof with two truck-mounted cranes. “Like an open-heart operation,” says Hahne. As he says that, down in hall garbage trucks dump their loads right on the concrete floor inside the open doors. It’s a confusion of plastic bags and everything else imaginable, including things that have no business being in residual waste, like devices with lithium batteries. Residual waste from some 566 thousand households and a good 41 thousand area companies is processed here. The scale is impressive.
