Natural Soil Improvement is the newest business unit within Triple E. In recent years, Natural Soil Improvement has developed a product called ‘Brickz®’. A European patent has been granted for this product. The organization has its own research and production facility in Huissen, called ‘Phytorefinery the Growing Place’ (Fytoraffinaderij de Groeiplaats), where also trees and biomass are grown. Brickz® are a combination of dredging (we prefer to speak of ‘river sediment’) and mycorrhiza, supplemented with other residual flows and life (seeds, tree seeds, worm eggs, etc.). This makes Brickz® an important new product within the circular economy, because river sediment is the largest waste stream in our country and we convert it into a product that can be used as a soil improver by means of Brickz®.
