The goal of this study is to find out if quality assessment by normothermic machine perfusion can be used to safely increase the number of usable donor livers, helping more people get transplants faster and with better results. This process keeps a donated liver working outside the body before transplantation, allowing surgeons to assess whether livers previously considered unsuitable can still be used. The main questions this study aims to answer are: * Does this method help patients get a transplant sooner? * Can this method make more livers available for transplant? * Does it improve survival and health after transplant? Participants in this study must be on the waiting list for a liver transplant with a ReMELD-Na-Score of 21 or less (equivalent to MELD ≤25) and must not qualify for certain special exceptions. Participants will be randomly placed into one of two groups: * Experimental group: In addition to regular organ offers, these participants may receive a liver that was initially not considered for transplantation but meets quality standards after at least four hours of machine perfusion. * Control group: These participants will receive a liver through the usual transplant process. The main measure of success is how quickly participants receive a transplant. Researchers will also look at other important factors, such as survival rates, quality of life, hospital stay, and complications after transplant. This study may help improve liver transplantation by making better use of available donor livers, reducing waiting times, and improving patient outcomes.
