L'uso del biopolimero MetaFLO ha permesso di ottenere notevoli risparmi sui costi, aumenti di produttivit\u00e0 e benefici ambientali per un progetto ferroviario su larga scala, accelerando il processo di stabilizzazione e riducendo l'uso di acqua.<\/strong><\/h4>\n

Location<\/span><\/strong><\/h3>\n

Alto Horizonte, GO, Brazil<\/p>\n

Challenge<\/span><\/strong><\/h3>\n

Conventional methods for regularizing railway backfill layers are resource-heavy, even when dealing with soils like silt that contain high levels of iron oxide. These techniques often rely on substantial water usage, leading to high operational costs and extended project timelines. To overcome these issues, there was a need for a more sustainable and cost-effective solution that could rapidly stabilize the soil while staying within budget and meeting project deadlines.<\/p>\n

Solution<\/span><\/strong><\/h3>\n

In this study, MetaFLO applied 0.01% of SoilTech biopolymer to a 280x12x0.35 m3 track, to demonstrate the technology\u2019s potential for road stabilization. When diluted directly in a water truck and applied to the track, SoilTech binds with the soil, forming a hydrogel while improving the soil\u2019s mechanical properties after it cures. The treated soil exhibited increased mass density, better compaction, enhanced layer stabilization, and improved impermeability.<\/p>\n

 <\/p>\n

Outcome<\/strong><\/span><\/h3>\n

\u2713 COST SAVINGS<\/h4>\n

Besides being much more environmentally friendly than traditional backfill regularization methods, SoilTech reduced fuel consumption and emissions of polluting gases by 35%, and workforce labor time by 2 hours\u2014resulting in total cost savings of 43%.<\/p>\n

\u2713 WATER SAVINGS<\/h4>\n

The use of SoilTech made it possible to reduce water consumption by 50%, saving a total of 60,000 litres of water throughout this project.<\/p>\n

\u2713 ROAD QUALITY<\/h4>\n

24 hours after curing, the soil displayed enhanced particle cohesion, improved compaction, and increased impermeability, leading to a more durable and resilient road surface.
