DREDGING operations could provide the materials of the future for brick production, according to a Belgian sediment and treatment firm Silt NV.
The company has signed an agreement with German brickmaker Hanseaten Stein Ziegelei, which is already producing up to 70,000, bricks a day from dredged materials.
Jef de Brabandere, Silt's technical commercial manager, said: 'The economics of brick production look promising for dredged materials with a low organic matter content. Treatment anddisposal options are relatively expensive and brick production represents an interesting alternative.'
He claimed that in laboratory tests, bricks made from dredged material performed as well as conventional ones.
