Birla Cellulose's Grasim Cellulosic Division, Vilayat, India has successfully commissioned the Carbon-disulphide Adsorption Plant (CAP) and has achieved the stringent level of sulphur-to-air emission norms stipulated in the EU BAT references (EU Best Available Technologies BREFs) for the viscose manufacturing process.
This initiative is in line with Birla Cellulose's aim to apply the best available technologies (EU BAT) at all of its fibre locations and investments of $170 million are in progress in order to achieve this by the end of 2022.
Grasim Vilayat has installed state-of-the-art closed-loop technologies to recover and recycle CS2, which is the key raw material for viscose manufacturing process. With these technologies, the site is able to significantly reduce its emissions and achieve 90-95% recovery in terms of sulphur and recycle it back to the process. In addition to this, the site also meets all other EU BAT parameters.
