Legioblock concrete blocks are made from secondary raw materials. This makes our Legioblocks environmentally friendly, sustainable and contributes to a ‘Blue Economy’. Where do we get these secondary raw materials and what exactly does a ‘Blue economy’ entail?
Secondary raw materials
Our lego concrete blocks are made from secondary raw materials. Secondary raw materials are substances that are released after the recycling of waste and which, after processing, can be used again as (certified) additives in, for example, the concrete products industry. By using secondary raw materials in concrete, the extraction of natural sand and gravel is avoided. For example, for the legioblocks we use mineral waste materials such as (concrete) rubble, this is certified and meets all quality requirements. Secondary raw materials fall under the principle of ‘urban mining’: instead of extracting new raw materials, we make use of many materials that become available when demolishing old buildings. We no longer see used raw materials as ‘waste’ but as valuable sources for new, secondary raw materials. So our legioblocks are made of environmentally friendly concrete and are incredibly sustainable.
