  We investigate the emergent universe scenario in the presence of interacting
fluids. The non-linear equation of state (EoS) considered in the general theory
of relativity for obtaining emergent universe is effectively a cosmological
model with a composition of three fluids. In this paper we consider two models
to realize viable cosmological scenarios, {\it viz.}, (i) a two-fluid model
with interaction of a pressureless fluid with the fluid having the non-linear
EoS needed for the emergent universe, and (ii) a three-fluid model with
interaction among the three fluids which originate from the EoS of the emergent
universe. It is found that realistic cosmological models in accordance with
observations are not ruled out for both the above cases. We further show that
the generalized second law of thermodynamics is found to hold good in the
emergent universe with interacting fluids.
