Study overview<\/h2> \n \n

A recent study examines the effectiveness of environmental bacteria for biocementation<\/strong> in the production of biocement<\/strong>. The study\u2019s lead author, Dimitrios Terzis, is an EPFL senior scientist and a co-founder of Medusoil<\/strong>, a company that produces mineral binders<\/a><\/strong> and that opened a biocement production plant<\/strong> in Vaud in 2024<\/a>.<\/p> \n\r\n

\n

\u201cFor me, it\u2019s essential to keep conducting fundamental research,\u201d<\/p> \n<\/blockquote>\r\n \n

says Terzis, a civil engineer at EPFL\u2019s Soil Mechanics Laboratory<\/strong><\/a>. <\/p> \n \n

His company Medusoil<\/a> produces bio-mineral binders<\/a><\/strong> that are similar to biocement<\/strong>. <\/p> \n \n

For the study he published recently in Scientific Reports, Terzis worked with scientists from the University of Applied Sciences and Arts of Southern Switzerland<\/a> to analyze 50 bacteria strains sourced from farmland in Ticino canton. <\/p> \n \n

This land is used for grazing dairy cattle and has shown to be particularly well suited for the production of Medusoil<\/strong>\u2019s biocement<\/strong> due to the widely available presence of calcium.<\/p> \n \n

\n Biocementation<\/strong> relies on stimulating a natural process: the secretion by microorganisms of an \n enzyme that triggers the formation of carbonate, which then binds with the calcium largely present in the soil \n to form calcite, a natural cement. \n<\/p> \n \n

The study identified which naturally occurring strains fabricate the enzyme required for carbonate formation and can be fermented \u2013 two factors that make them prime candidates for biocement<\/strong> production. <\/p> \n \n

The scientists created a culture of the most promising strain, which was inoculated in a 1.5-meter-high column of sand. <\/p> \n \n

After 24 hours of infiltration, the column was strong enough to sustain its weight and to be used in a variety of geotechnical engineering<\/strong> and geoenvironmental applications<\/strong>, like erosion control<\/strong>. The scientists also found that using this strain could cut production costs by 40%.<\/p> \n \n

A paradigm shift in sustainable construction<\/h2> \n \n

Medusoil<\/a><\/strong>, founded seven years ago, supplies organic binders<\/strong> whose carbon impact is at least 55% lower than that of standard cement, which is made by heating an 80% limestone \/ 20% clay mixture to high temperatures. Biocement<\/strong> can be used in a number of geotechnical<\/strong> and building applications<\/strong>, such as to reinforce dams<\/strong>, prevent soil erosion<\/strong> by wind and help protect areas subject to landslides<\/strong>, earthquakes<\/strong> or cyclic loads induced by road and railway traffic.<\/p> \n \n

To test yet another application, the company\u2019s biocement<\/strong> was used in a project in Geneva to recover concrete aggregates from demolished buildings. And because biocement<\/strong> can be employed several times, it supports the circular economy<\/strong>. <\/p> \n \n

In the Scientific Reports study, the authors note that this naturally occurring biocementation<\/strong> process can be applied at a large scale and can help drive a paradigm shift towards greater sustainability in the construction industry.<\/p> \n \n

New biocement production plant in Vaud<\/h2> \n \n

Medusoil<\/strong> reached a new milestone in 2024 with the opening of a production plant in Molondin<\/strong>, near Yverdon-les-Bains. \u201cThe plant can generate 400,000 liters of biocement<\/strong> per year, which is enough to stabilize five kilometers of riverbank against erosion<\/strong>,\u201d says Vincent Lauren\u00e7on, Medusoil<\/strong>\u2019s head of manufacturing.<\/p> \n \n

The company also has a mobile biocementation plant<\/strong> designed to make use of local raw materials. It was recently transported by truck to Romania, for example, where it was employed to reinforce roads<\/strong>. The firm intends to pursue its cutting-edge R&D and has projects lined up this year in France, the Middle East and the Netherlands.<\/p> \n \n
