The Group's activities are characterised by the circularity of the products used: all steel and rockwool waste is recovered to create new raw material. Manni Group purchases materials that meet precise standards in terms of the percentage of recycled content. The products are suitable for international sustainable construction certifications, which state that the origin of the material used must be tracked and disclosed, something which is also required in public procurement under the European Union's Green Public Procurement plan. Minimum percentage of recycled content in steel purchased by the Group in 2023*
*recycled content is the percentage by weight of secondary raw material used in the production of a product. The recycled content is estimated on the basis of ISO 14021 compliant declarations and EPD certificates from only those suppliers who have provided this information.
Environmental Product Declarations (EPDs): documents that describe the environmental impacts of a product or service throughout its life cycle. EPDs allows credits to be earned for sustainable construction certifications, such as LEED or BREEAM, or for demonstrating the environmental parameters required by public procurement programmes, such as Minimum Environmental Criteria.
In 2019, Manni Group produced and published the first EPDs for Isopan SpA sandwich panels. Thanks to the experience gained by Isopan's Italian sites, the project was extended to other solutions and production plants in Europe (Isopan Est, Isopan Deutschland, Isopan Ibérica) and Mexico (Isocindu). Complying with the principles and requirements of the Product Category Rules (PCR), Life Cycle Assessment (LCA) studies were conducted and the subsidiaries obtained EPD certificates in 2023.
Isopan solutions are the first in Europe to be awarded the Declare label, a nutritional label for construction products, which lists all of the component parts of a product and shows the possible presence of Red List chemicals. The ILFI (International Living Future Institute) database helps designers identify materials that meet the green building requirements of certifications such as LEED and WELL, LBC and Core Green Building.
The Declare labels for Isopan Leaf and GreenROOF solutions are constantly updated.
