In the tendering procedure for the disposal of controlled goods in Northern and Central Hessen, the ZT was able to win the contract only because its fixed costs for maintaining reserve capacity were already covered by the annual contribution and it was therefore able to offer lower rates of charges.
ZT võitis pakkumismenetluse 1. ja 2. kategooria materjali kõrvaldamiseks Põhja- ja Kesk-Hessenis üksnes seetõttu, et tema tootmisvõimsuse hoidmise püsikulud olid juba kaetud iga-aastastest tasudest ja ta sai seega pakkuda madalamaid teenustasumäärasid.
