The space debris related aspects can be summarized in terms of: prevention, protection, mitigation and regulation. To tackle these issues, the project called Revolutionary Design of Spacecraft through Holistic Integration of Future Technologies (ReDSHIFT) was funded by the European Union in the framework of the PROTEC Call of Horizon 2020 (see [[http://redshift-h2020.eu/](http://redshift-h2020.eu/)]([http://redshift-h2020.eu/](http://redshift-h2020.eu/))). With 13 European partners, ReDSHIFT is a very large project gathering results on a wide range of open problems in the realm of the space debris related studies. It is grounded on two main pillars, a theoretical and an experimental one. While these two pillars appear to belong to different areas of interest, it is important to approach both fields in a single project with the goal of finding links and synergies that can enhance the effectiveness of the solutions found in the study. The main purpose of this paper is to briefly describe the main results of the project achieved so far trying, where possible, to highlight the connections between the theoretical findings and the experimental achievements. The theoretical part of ReDSHIFT is mainly based on a complete mapping of the Low Earth Orbit (LEO) to Geostationary Orbit (GEO) space looking for \"dynamical\" disposal strategies for any orbital regime, exploiting natural perturbations to spacecraft orbits. Some preferential deorbiting routes, dubbed \"deorbiting highways\", result from specific resonances populating the different orbital regimes involving gravitational and non-gravitational perturbations.
