Disposing of or land-filling concrete residues is expensive and wastes valuable resources. One of the low-cost options for reusing this concrete is to proc-ess it to concrete blocks suitable for a wide variety of structures, including walls, retaining elements or bulk-material boxes. Betonblock/Legoblock BV, a company based in Stompeto-ren, Netherlands, offers concrete block molds developed specifically for this purpose.

These molds are produced at the company’s own factory. They are made from high-quality, low-alloy structural steel that is exceedingly durable thanks to its powder coating....
