**3.7 Use of reclaimed or bio-based materials**

This is a design strategy that involves the integration of recycled or reclaimed materials or components or the specification of bio-based or circular materials in a new building wholly or partly to enhance the closing and slowing of the resource cycles. Bio-based materials possess several advantages that dispose of them for use as circular materials [51]. In regions with a large stock of buildings for renovation, bio-based products can be deployed to contribute to circularity [52]. It has also been shown that agro-industrial wastes can be converted to building materials thereby contributing to sustainability and circular economy [53].
