Due to the constantly developing road network, a large number of new Motor Rest Area facilities are being built. The aim of the work is a critical assessment of the current wastewater management in the MRA and the proposal of appropriate solutions capable of purifying wastewater. The analysis of the current state of the MRA facilities was carried out on the basis of maps, own observations and an assessment of interest in the subject recently by reviewing publication resources. For this purpose, analyzes of the frequency of occurrence of keywords describing the issue were used. The solutions used so far are ineffective. This is mainly due to the perception of wastewater produced in MRA facilities as domestic wastewater. This assumption leads to the selection of inappropriate solutions, which in the long run can lead to an ecological disaster by introducing untreated sewage into the environment. The authors point to the possibility of introducing a circular economy in these places to relieve their environmental impact. Since, wastewater generated in MRA facilities, due to its specificity, is very difficult to treat. They are characterized by uneven inflow, a lack of organic matter, a low C:N ratio and very high concentration of ammonium nitrogen. Conventional activated sludge methods cannot cope with this. The need for changes and the use of solutions suitable for the treatment of wastewater with a high content of ammonium nitrogen has been demonstrated. The authors presented solutions that have the potential to be used in MRA facilities. The application of the proposed solutions from that moment will undoubtedly change the impact of MRA facilities on the environment and solve the problem of wastewater management on a large scale. There is still a lack of research on this thematic scope, which is a challenge authors have taken up.
