New Construction Methods Use Living Building Material

The world as we know it is rapidly declining and changing that is why with the rising environmental issues such as pollution, desertification, global warming, it is only natural that man will want a sustainable material. This article does cover one of these Sustainable materials which are being used in the construction of buildings. This new constriction method research is centered around the development of a new living material that combines biology, polymers, and cement chemistry to form a biometric material. The development of this material can help in the fight against climate change. Now, what are these living building materials?

Living building materials

They are known as biological building materials through which microorganisms join in the manufacturing of the material. The bacterias and microbes work hand in hand like mini-factories to develop the building material that can self regenerate, live, absorb harmful toxins. 

Can living building material eradicate pollution?

Study shows that among the widely used materials during the construction of a building, cement is the most widely used building material and is also the largest source of industrial pollution. Conventional buildings are also responsible for playing a part in pollution due to carbon emissions. Living building material can be able to reduce the environmental pollution caused by the cement industry if it replaces the use of cement.

The development of the material

Many factors contributed to the development of this material and one of them is nature. Inspired by the way natures works and how organisms live. One observation is that of the corals known to secrete limestone and the coral reefs which form due to colonies of corals polyps held strong by calcium carbonate. By paying attention, scientists learn how nature works and develops to achieve things efficiently and cleverly.

Producing living materials

A team led by Wil Scrubar experimented with cyanobacteria which belong to the genus Synechococcus to create a variety of shaped building blocks. These photosynthesis organisms use carbon dioxide, water, and sunlight to grow and manufacture the building material. This way this invention will play a key role in the absorption of carbon from the atmosphere and combat climate change. Now, colonies of cyanobacteria are then introduced into a solution containing gelatine and sand. Due to certain conditions, these microbes can absorb carbon dioxide helping them grow and produce limestone. Hard brick is attained from the chemical reaction when calcium carbonate mineralizes the gelatine and binds with sand to create the bio cement. To top it up, the most interesting part of the entire process is that these living bricks grow into new brink and reproduce in ideal conditions. Therefore, if these materials can grow biologically then they can be manufactured. But one of the major drawbacks is that the living building materials cannot survive or multiply in arid conditions they only survive in humid conditions.They can be the next modern advancement that’ll help solve not only polution from buildings but vast areas in time.
