iHAUS explores the use of biomaterials and bioadditives in construction, emphasizing also on the exploitation of construction and demolition waste (CDW). These waste streams serve either as feedstock for new materials or supports biorefinery processes.
Specifically, iHAUS aims to develop bio-based construction materials, including low CO2 concrete from C&D waste and bio-cement using microbial induced calcite precipitation (MICP). It also intends to produce bio-based resins, foams, and bricks/tiles/boards from renewable resources like plants, seaweeds and paper pulp. The iHAUS proposal will promote a circular economy in construction by processing C&D waste, encouraging the reuse and recycling of construction materials to minimize landfill impact. Another objective is to enhance the functional properties of materials by developing components with improved performance, such as self-healing properties and enhanced durability, and creating bio-based products with benefits like air purification and fire retardancy. The project will also ensure that the novel materials are compatible with existing construction practices and comply with safety, health, and environmental regulations.
