The picture symbolizes a section view of AortaCity.

The blue area is the sky and the grey area the ground. The high brown rectangles symbolize apartment modules and the high yellow rectangle symbolize office modules. The small white squares symbolize the different underground systems of AortaCity.

Sewage and organic waste is distributed by those underground systems to stations where it is rot into methane gas.

Energy and materials are produced, processed and recycled to retain the balance in the ecosystem for the next 500 of years to come.

In the AortaCity structure these systems are located underground:

• Long distance automatic goods transport systems (rail).

• Short distance automatic goods delivery systems (conveyors).

• Long and medium semiautomatic person transport systems (rail).

• Water pipelines, electricity and IT cable systems

• Heating/cooling systems

• Other energy supply systems  like hydrogen, methane and alcohol pipelines.

• Recycling systems for sewage, organic waste and other waste

Sewage and organic waste is distributed by the underground systems to stations where they are rot into methane gas. The methane gas is used by vehicles outside the AortaCity structure. Inside the AortaCity structure only electricity is used for all transport systems. Other waste is by category dropped down to the underground recycling system, sorted at stations and recycled by the parallel industry AortaCity line.

Energy and materials are produced, processed and recycled in order to retain the balance in the ecosystem for the next 500 of years to come. The AortaCity is carbon dioxide neutral.
