The iron casting process in the Mapello oven
Brembo is active in its approach to the circular economy with projects that involve both the product and the production process. As far as the production process is concerned, the areas for intervention aim to reduce the quantity of waste generated, as well as the possibility of re-using self-produced or third-party waste material.
Noteworthy is the start in 2020 of the pilot project in which the used alkaline batteries are utilised within the cast iron melting process in the Mapello oven. One of the main elements of the cast iron alloy is manganese, normally obtained by adding the iron-manganese alloy of primary origin to the compound; the same result is obtained using the manganese contained inside the used alkaline batteries.
This process results in an advantage for the environment, allowing safe and total disposal of waste that would otherwise be difficult to reuse, whilst at the same time reducing the environmental impact arising from the substitution of melting additives originally of primary origin.
Some of the main benefits obtained were:
• the disposal of used alkaline batteries;
• no change in the quality of the cast iron produced;
• no change in the plant’s environmental impact;
• a reduction in the product’s environmental impact throughout the entire life cycle.
