3D printing can help fight coastal erosion
The main reasons for this natural phenomenon are the depletion of soil organic matter (sand, rocks), as well as the deterioration of the soil structure or problems with salinization and acidification.
And it's a huge global problem that's only getting bigger because of climate change.
In fact, according to the US Climate Resilience Toolkit, in the US alone, coastal erosion is responsible for about $500 million a year in coastal property loss, with average shoreline recession rates of between 25 and 50 feet per year not uncommon in some parts of the country.
To combat coastal erosion, there are a number of different initiatives that have been put in place.
One of them integrates the 3D printing process to produce biodegradable structures.
In collaboration with BESE, Australian researchers from the Blue Carbon Lab at Deakin University are using this technology to support the growth of species in wetlands and thereby combat coastal erosion.
The idea is to place mangrove seeds in 3D printed mesh frames in Port Phillip and Western Port Bay, Australia.
Enhancing coastal ecosystems through 3D printing
Called BESE-elements®, the 3D printed structures are made from compostable potato starch obtained from industrial waste. And although no information was given on the technology used, with this type of material FDM 3D printing certainly seems like a possibility. These mesh frames are manufactured by BESE, a company that specializes in designing products to restore natural habitats. They degrade naturally after 2 to 10 years, depending on the ecosystem in which it is used. The structures are designed to encourage the growth of mangrove seed roots. Due to their lattice shape, they slow down the movement of water, which allows the soil to recover better and accumulate water. In addition, the structures stabilize the plant to prevent it from detaching from the soil.
The choice to plant mangroves is calculated. These plants are known to protect the coast from erosion and extreme weather events. They also contribute to water quality by filtering nutrients and sediments. With this project to combat coastal erosion, Blue Carbon Lab researchers also want to educate the public, industry and stakeholders about how restoration techniques can benefit local communities. According to BESE, BESE-elements® can even help re-vegetate ecosystems in Europe and North America. To learn more about this project, watch this video explaining how these structures work.
