The room temperature BEC is formed from Polaritons. DGT has said that their BEC was a Polariton BEC. DGT (also assume Rossi) uses micro-particles to create their Polariton BEC, and IBM uses plastic.
Details from the expanded article as follows: Polariton BEC within the polymer-filled micro-resonator consisting of the luminescent polymer layer (yellow) and the two mirrors each consisting of many pairs of different transparent oxide layers (red and blue). The polaritons are created by excitation of the polymer layer from below with a laser beam (white). The polaritons (green), which are bosons composed of photons and electron-hole pairs, are formed through interactions of the polymer with the microcavity. Once a critical density is reached, the polaritons undergo Bose-Einstein condensation, emitting green laser-like light through the top mirror.
