In order to decrease the environmental impact caused by the construction sector, biobased materials need to be further developed to allow better integration and acceptance in the market. Mycelium composites are innovative products, with intrinsic properties which rise the attention of architects, designers and industrial companies. Both mycelium foam and board material have the potential to substitute conventional toxic materials. The mechanical properties of these products are influenced by their production process. For example, bending and tensile strengths have shown to be higher in heat pressed samples (F. V.W. Appels, 2019). The heat press process related to mycelium boards, needs further development in terms of process timing and of parameters, as temperature, pressure and duration of pressing. It is the need to research mycelium boards which drove the partner companies to approach the Centre of Expertise BioBased Economy (CoEBBE). The project partners are the following: KNN Cellulose BV, Fungalogic and V8 Architects. The interest of each partner is focused on different aspects of mycelium boards, which can be summarised in the following questions:
• Is it possible to use cellulose to produce mycelium composites? (KNN Cellulose)
• What are the different production parameters and how can these be optimized? (V8 Architects, Fungalogic)
• What are the mechanical material properties and (how) can mycelium boards be used for interior or construction purposes? (V8 Architects, Fungalogic)
These questions merge together in the research question: is it possible to create a mycelium board with cellulose biomass that can be used as a substitution of conventional board materials? The developed research will bring specific knowledge to each involved partner. In particular, KNN Cellulose will have a new application for their product; Fungalogic will acquire knowledge on board materials and have a potential new product; V8 Architects will gain specific knowledge on mycelium products.
