Respyre, a Dutch start-up, has developed an innovative bioreceptive concrete designed to facilitate moss growth on vertical surfaces. This eco-friendly material is composed of recycled concrete aggregates and other residual streams, creating an ideal environment for moss proliferation.
The process begins by applying the bioreceptive concrete to a surface, followed by a specialised bio-gel that provides moss spores with necessary nutrients, water, and shelter. Initially, a temporary irrigation system supports the moss's early growth stages. Within approximately 12 weeks, the moss matures into a self-sustaining layer capable of withstanding various environmental conditions with minimal maintenance.
Unlike traditional plants, mosses anchor themselves using rhizoids—tiny hairs that do not damage the underlying structure—making this solution suitable for both new constructions and existing buildings. The presence of moss not only enhances aesthetic appeal but also improves air quality by absorbing carbon dioxide and nitrogen oxides, converting them into oxygen, and removing particulate matter. Additionally, moss acts as a natural insulator, trapping moisture and air to reduce heat transfer through walls.
By integrating this bioreceptive concrete into urban environments, Respyre aims to enrich cities with the power of nature, creating green facades that contribute to a healthier and more balanced ecosystem.
