The Bio Gas Unit, which was ceremoniously opened by the College officials, including the Principal, Mr. Upali Gunasekera, has been of great use in terms of helping reach the goal of desired energy consumption, thereby leading to an improved level of sustainability.

The Bio Gas Unit has been instrumental in decreasing the cos of L.P gas of the Royal College Hostel, by a massive 50%, which is a large amount not only in monetary terms, but also in terms of the amount of energy and gas saved. The Bio Gas unit is currently in the forefront of Energy conservation and sustainable contributions, along with the Rain Water Harvesting Mechanism.
