The production cycle of bricks is a virtuous and concrete application of the principles of the circular economy, as it is able to obtain many materials that can act as partial substitutes for clay or slimming aggregates.
The commitment and research we carry out every day have led us to select the best supplies of materials suitable for this purpose, both special waste and MPS, thus allowing us to offer our partner furnaces an important aid in the production of eco-sustainable bricks. , without sacrificing the quality of the finished product.
FOUNDRY WASTE MOULDS & CORES
- EER 100908 & EER 100912 – Foundry waste moulds and cores come from ferrous metal foundries, and represent the exhausted sands no longer usable for casting molds. These contain SiO2 in a percentage of 70% and have a high COT content, thus ensuring an excellent energy contribution in the firing phase and therefore making them suitable for use in raw materials for the production of bricks.
ASH FROM WOODY BIOMASS
- Wood biomass ashes EER 100101 from waste-to-energy plants with virgin woody biomass (wood chips) represent specifically the heavy grid ash, not dangerous, containing a percentage of silica, iron oxides and aluminum used as a corrective of raw materials for production of cement, contributing significantly to the reduction of the use of natural silica otherwise coming from mining activities.
PAPER MILL SLUDGE
- The sludge deriving from the purification of waste water from the paper industry is a very interesting material for recovery in the brick industry, as it is characterized by a content of organic substances of about 20% of the dry weight, with a calorific value of about 2000 kcal / kg which facilitates cooking of the product.
