Bio Based Building Materials
overall review score: 4
⭐⭐⭐⭐
score is between 0 and 5
Bio-based building materials are construction products derived from renewable biological resources, such as plants, fungi, and other organic matter. They are designed to serve as sustainable alternatives to traditional non-renewable materials like concrete, steel, and synthetic insulations, aiming to reduce environmental impact and improve the sustainability of the construction industry. Examples include bamboo, hempcrete, mycelium composites, cork, and cellulose-based insulations.
