b. Recycled Plastic:

Plastic waste can be recycled into wood composite, insulation and roofing tile and other building materials. The use of recycled plastics helps reduce waste disposal and the demand for raw plastics, which are energy-intensive and non- polluting.

c. Reclaimed Wood

Reclaimed wood is sourced from old buildings, bridges and other structures. It adds a unique aesthetic to new construction and reduces the need for new trees, preserving forests and reducing carbon footprints associated with harvesting and processing trees.

3. Innovative Eco-Friendly Materials:

a. Hempcrete:

Hempcrete is a bio-composite blended with a powder-based binder derived from the fibers of the hemp plant. It’s lightweight, protective, and carbon-negative, because the hemp plant absorbs carbon dioxide as it grows. The walls are made of hempcrete, which provides heat and sound insulation.

b. Ferrock:

Ferrock is a durable concrete alternative made from recycled materials, including metal dust and silica. It is stronger than traditional concrete and absorbs carbon dioxide as it is produced, making it carbon negative. Ferroc is used in building products, reducing the carbon footprint of the construction industry.

c. Mycelium:

Mycelium, the root component of fungi, can be grown in pots to make lightweight, biodegradable building materials. Mycelium-based products are used for insulation, wall panels and even furniture. They are renewable, compostable and require little energy to produce.
