The Tuas Marine Transfer Station (TMTS) is an intermediate collection point for ash from waste-to-energy plants and non-incinerable waste before these are transported to Semakau Landfill. Constructed at the same time as Semakau Landfill, it is located next to the Tuas South Incineration Plant.
All incoming licensed collection vehicles carrying non-incinerable waste are first weighed at the weighbridges before they enter the transfer building. Vehicles carrying incinerated ash to TMTS are also weighed.
The reception hall is designed for a quick turn-around time with 20 overhanging discharge bays for the vehicles to unload waste directly into the barges. The tipping platform is designed to overhang into the barge so that refuse is tipped into the centre of the barge. Excavators are used to spread the refuse in the barge to ensure that it is optimally loaded.
The empty vehicles that carried non-incinerable waste to TMTS are weighed again. This allows the weight of waste delivered to be determined. At the end of the day, the hatch covers of the fully loaded barges are closed to shield the load from the wind and water during the 33.3km sea journey to Semakau.
