MSM Malaysia Holdings Berhad Annual Report 2020

SUSTAINABILITY REPORT WATER USAGE GRI-303:Water & Effluents Vast water quantities are used in the sugar refining process. Sustained water management measures have been adopted to ensure the efficiency of water usage within our operations. The amount of water used and reused in our daily operations are constantly measured and monitored. Water consumption in MSM Johor was lower for FY2020 due to a process improvement activity. Meanwhile in MSM Prai, higher water consumption was recorded due to the plant’s lowest ever melting efficiency in April and May 2020 as a result of the significant drop in demand during the MCO period. ENERGY OPTIMISATION GRI-302: Energy We have invested heavily in back pressure turbines to generate approximately half of our energy requirements by channeling exhaust steam back to the heating process. We also recycle our process condensate for boiler steam generation. Where necessary, we use clean natural gas as an energy source at both refineries to reduce production of carbon soot and sulphur emissions. In addition, we employ an innovative system that combines functionalities of our Mechanical Vapour ReCompressor (MVR) evaporator and Vertical Crystallisation Tower (VKT) to dramatically reduce the amount of steam required during the sugar-boiling processes.

In FY2020, MSM used more of our own generated electricity compared to electricity purchased from TNB. TNB supply is only required when the generator trips or during plant shutdowns. We continue to pave the way for further reduction in electricity consumption.
