  The breakdown of SU(6) global symmetry down to its SU(5) subgroup near the
scale f > 10 TeV in the strongly interacting sector within the E_6 inspired
composite Higgs model (E6CHM) gives rise to a set of pseudo-Nambu-Goldstone
bosons (pNGBs) that involves one Standard Model (SM) singlet scalar, a SM-like
Higgs doublet and an SU(3)_C triplet of scalar fields, $T$. We argue that the
baryon number violation in the E6CHM can induce the observed matter-antimatter
asymmetry if CP is violated. The coloured triplet of scalar fields with mass in
the few TeV range plays a key role in this process and may lead to a distinct
new physics signal that can be detected at the LHC in the near future.
