Energy Circulation CityIntroduce

The Energy circulation city is located in Patong Beach, Phuket Island. The city converts collected
plastic waste into hydrogen energy and food waste into thermal energy, which can be used forvarious city functions. The sludge obtained as a by-product is used as fertilizer to grow forests. As aresult, forests and oceans will become cleaner, and the number of tourists will increase. The increasein the number of tourists will have an economic eﬀect, and at the same time, the amount of waste will
increase, and more energy can be produced. In this way, this city will create a cycle of waste andenergy, enhancing both environmental issues and the economy.

Energy circulation

Desing concept

Trash circulation

The city is designed so that energy ﬂow and waste ﬂow appear. This design implies that the energy
ﬂow and the waste ﬂow are connected by a single line, thus creating a cycle.
