  Tidal Disruption Events (TDEs) are processes where stars are torn apart by
the strong gravitational force near to a massive or supermassive black hole. If
a jet is launched in such a process, particle acceleration may take place in
internal shocks. We demonstrate that jetted TDEs can simultaneously describe
the observed neutrino and cosmic ray fluxes at the highest energies if stars
with heavier compositions, such as carbon-oxygen white dwarfs, are tidally
disrupted and these events are sufficiently abundant. We simulate the
photo-hadronic interactions both in the TDE jet and in the propagation through
the extragalactic space and we show that the simultaneous description of
Ultra-High Energy Cosmic Ray (UHECR) and PeV neutrino data implies that a
nuclear cascade in the jet develops by photo-hadronic interactions.
