The Company intends to use majority of proceeds raised to secure more sludge treatment projects and Al water management projects. The sludge treatment projects are expected to generate one-off engineering, procurement and construction (EPC) income during the construction of the projects, and upon completion, generate recurring income for the Group over the lifespan of the projects, which is generally between 25 to 30 years.
