This invention aims to provide a material to be used for the production of components used in the construction industry such as construction blocks, wall panels, floor and roof tiles, lintels. The material is a paper concrete made with 50% to 90% of recycled paper in the base mixture. This invention also aims to provide a process for making a construction block with the base mixture of paper concrete. The process for making the lightweight building blocks with this paper concrete has three main steps with two stages each. The two first steps of the process include the preparation of the raw material and the mixture, while the following step aims to achieve a construction block by forming and compressing the mixture. Thereafter, there are possibilities for producing these blocks with different colours by adding pigment to the paper pulp during its treatment and adding artistic moulds on the block making machine during the forming stage.

A building panel comprising a base panel (20) made of a material including a binding material and a recycled material. The base panel comprises a load-bearing core. The use of recycled materials in the manufacture of the building panels is advantageous, as it reduces environmental impact, while the provision of the load-bearing core in a building panel incorporating recycled materials allows the building panel to be used in a load-bearing of a building.
