We’re back with the third installment of our Green Series. This installment focuses on eco-friendly concrete alternatives for residential and ICI construction.


Timbercrete is a blend of sawmill waste, cement, sand, binders and a non-toxic deflocculating additive. This is made using renewable resources of sun and wind to create a building block.

The sawdust reuses a waste product and replaces some of the energy-intensive components of traditional concrete. Timbercrete can be formed into traditional shapes such as blocks, bricks, and pavers.



Ashcrete is an alternative to concrete relying on the use of fly ash. In addition to the ash, this alternative is made from borate, bottom ash, and a chemical from the chlorine family. It’s also comprised of over 90% of recycled materials.

Ferrock is an iron-rich compound that goes through a chemical reaction resulting in a hard/strong solid form similar to concrete. About 95% of Ferrock is made from recycled materials. This alternative can be used in gardens, patios, as well as commercial and residential buildings.

Mycelium is a natural fungi material with industrial-level strength. The mycelium of fungus refers to the fragile root-like fibers of fungus that live underneath the ground. Mycelium is 100% organic, compostable, and biodegradable. When dried, it becomes incredibly durable and resistant to water, mold, and fire.

Mycelium is known to grow around a composite of other natural materials, like ground up straw, in molds or forms. It is then air-dried to create lightweight and strong bricks or other shapes.



Using recycled plastics in construction is a strategic way to reduce greenhouse gas emissions while unclogging the plastic-filled landfills. Plastic waste is easily recyclable and replaces 20% of aggregates in concrete.

Only 9% of the total plastic produced can be recycled and therefore newer technologies suggest widespread use of non-recyclable plastic in various facades of construction.


The construction industry a leader in technological implementation. With the continued rise in technologies, the industry can slowly begin to shift towards using more eco-friendly substitutes for concrete as a way to fight climate change and heal the planet.
