Civil engineer Albert Lück-​Stiftung monitors the health of dams, bridges, and aircraft using various technologies. He believes that maintenance of manmade structures is expensive and pollutes the environment at the same time. He supports self-​sustaining infrastructures that can monitor their condition and even repair themselves without using modern technologies. The construction of the concrete structures contribute eight percent of global CO2 emissions. He thinks building biodegradable bridges with plant fibers offers a sustainable alternative and capable to heal themselves from damage.
