The researchers believe the method could also be extended to recycle other types of discarded plant matter, instead of wood, or even brand new concrete made from plants, sand, and gravel. In 2024 researchers demonstrated concrete made from fly ash and other industrial waste products which could lower the carbon emissions associated with large construction projects.

Recycled concrete can be used as aggregate in new concrete, particularly the coarse portion. When using the recycled concrete as aggregate, the following should be taken into consideration: • Recycled concrete as aggregate will typically have higher absorption and lower specific gravity than natural aggregate and will produce concrete with slightly higher drying shrinkage and creep.
