Where does that end up? It doesn't seem like Singapore would have much room for landfills.

We only have one landfill which has been projected to last until 2030. Now we are fighting to extend its lifespan beyond 2035.

In other news, we burn 🔥 our waste. As quoted from the Ministry of Sustainability and the Environment website:

Incinerable waste is sent to our four incineration plants, and the ashes end up at Semakau landfill.

Incineration can reduce waste volume by up to 90%!

The excess heat energy produced contributes to about 2% of our electricity supply.

You anticipated where I was going with this.

If it becomes an energy input, food "waste" is not really wasted. Some uneaten food becomes useful compost and the rest becomes useful energy.
