  We use a combination of computer simulations and iso-flux tension propagation
(IFTP) theory to investigate translocation dynamics of a flexible linear
polymer through a nanopore into an environment composed of repulsive active
rods in 2D. We demonstrate that the rod activity induces a crowding effect on
the polymer, leading to a time-dependent net force that facilitates
translocation into the active environment. Incorporating this force into the
IFTP theory for pore-driven translocation allows us to characterise
translocation dynamics in detail and derive a scaling form for the average
translocation time as $\tilde{\tau} \sim \tilde{L}_{\textrm{r}}^{\nu} /
\tilde{F}_{\textrm{SP}} $, where $\tilde{L}_{\textrm{r}}$ and
$\tilde{F}_{\textrm{SP}}$ are the rod length and self-propelling force acting
on the rods, respectively, and $\nu$ is the Flory exponent.
