The materials and raw materials used during construction works have a direct and indirect impact on the environment. The consumption of materials and raw materials represents a significant share of our organisation’s overall carbon footprint. The consumption of materials and raw materials is therefore monitored, leading to an optimisation of their use and a reduction in the amount of waste produced.

Asphalt, concrete, cement, wood, plaster, aggregates, lime, paper and steel are important materials and raw materials used in Unibep Group companies.

In subsequent reporting periods, the Group plans to expand the scope of reported data on the consumption of materials and raw materials. This will be possible once the necessary analyses have been carried out, taking into account the diverse business profile of the Group’s various entities.

Unihouse S.A. obtains its most important raw material, wood, mainly from certified crops. The use of wood, OSB and plasterboard is minimised by optimising the use of these materials already at the design stage. Residual materials are used for purposes such as the construction of smaller buildings.

Unihouse S.A. participates in the Cleaner Production Academy, which promotes a modern environmental strategy and the practice of pollution- and waste-free production. Thanks to cleaner production designs, we use wood, OSB and fibre cement boards that are too small to be incorporated into modules to make cat houses, hedgehog houses, bird feeders and nesting boxes. Thanks to cooperation with local schools, kindergartens, animal shelters, community social homes and forest districts, animals find shelter in these houses.

We place great emphasis on the correct segregation of waste and its subsequent recycling.

Film, paper, cardboard, plasterboard and mineral wool are segregated and recovered from waste generated during plant operations. Waste generated on construction sites includes rubble, wood and steel.

Unihouse S.A.’s modular construction technology fits in perfectly with the trend towards energy-efficient and environmentally-friendly construction. Wood from planned forest management is a renewable and energy-efficient material. It acts as a climate regulator and its waste is a secondary raw material, especially for energy generation and CO2 storage.

Being aware of the impact of the materials and raw materials used, we attach great importance to the proper development of our construction portfolio and to the optimisation not only of the project itself, but also of the issue of material suppliers and subcontractors, which is our plan for the coming years.

Data on the consumption of materials and raw materials is based on accounting data recorded in Microsoft Dynamics AX 2012. The following principle is adopted: material purchased = material consumed. Based on their characteristics, the materials are classified into different material groups.
