This year's World Cup in Qatar is one of the most expensive World Cups ever. Except for the stadium, the budget was spent on Hamad International Airport, the city subway, and other infrastructures that would remain after the World Cup. The most important of these is Lusail, a high-tech smart city that has cost about $45 billion. Lusail is a new city built with the goal of forcibly eliminating fossil fuels and sustainable development in Qatar.

As a country in the desert area, Qatar relies heavily on indoor air conditioning units with high temperatures approaching 50 degrees Celsius in the midsummer. However, in Lusail you can’t find any outdoor air conditioning units. This is due to the world's largest adoption of district cooling, a centralized cooling system, by the entire city. District cooling uses water as a refrigerant instead of freon gas, so there are no carbon emissions and the electricity consumption is low.

Another high-tech infrastructure for Lusail is a pneumatic waste collection system. Lusail chose PWC like London, England, to reduce fuel consumption and emissions from the process of collecting garbage. In addition, waste collection pipes have been laid throughout the city which are connected to public bins throughout Lusail.

The vacuum suction device sucks up the garbage at 22 meters per second and delivers it to the collection site in a one-stop manner. The collected garbage is divided into four containers, and they are well managed. The garbage is not visible nor does it emit a foul smell. This is because all waste is only moved in steel pipes, and odor removal and carbon capture treatment are also carried out during the process. Like this, Qatar is showing enthusiasm to build an eco-friendly national power grid such as establishing the garbage collection system in the wake of the World Cup.
