DusTech améliore la qualité de l'air et permet à un chantier de construction d'économiser 360 000 litres d'eau par jour

Alors que la suppression des poussières devient obligatoire en raison des préoccupations sanitaires et environnementales, le biopolymère à action rapide de MetaFLO offre une solution peu coûteuse et efficace pour améliorer la qualité de l'air sur les chantiers de construction.

Challenge

Excessive airborne dust particulate matter caused by civil works has increasingly become an environmental and health concern. Dust harms the environment, compromises human health, negatively affects communities and reduces overall business productivity. Traditional methods for dust suppression usually require large amounts of water—typically 5-9 water trucks per day—which is costly both logistically and environmentally.

Solution

MetaFLO first applied 3.0% of DusTech biopolymer, which was diluted directly in a water truck and applied with a lateritic gravel and silt soil characterization. By promoting greater agglutination between soil particles, DusTech significantly reduces dust suspended in the air. It creates a layer on the surface of the soil that minimizes the release of fine particles into the air through a clumping process. A second layer was applied after 17 hours, with a 2.0% dosage.

Outcome

✓ COST SAVINGS

By using DusTech, costs of labor and machinery were cut by 50%, as were fuel consumption and emissions of polluting gases.

✓ WATER SAVINGS

Water consumption on this project decreased by 50% with DusTech, saving 360,000 liters of water per day and reducing the need for additional surface moistening.

✓ ROAD QUALITY

MetaFLO’s biopolymer resulted in better agglutination of the soil, enhancing road safety, increasing traffic visibility and improving the air quality for employees, the environment and the surrounding communities.
