Old Concrete Gets New Life as Ocean Reefs
25 Jul
Summary
- North Carolina recycles concrete for artificial reefs, saving landfill space.
- The program has created about 1,100 acres of fish habitat since the 1970s.
- Recycled concrete offers a cost-effective way to support marine ecosystems.
In North Carolina, discarded concrete from bridges and public works projects is being given a new purpose as the foundation for artificial reefs. This practice, ongoing since the 1970s, diverts substantial waste from landfills.
The state's Artificial Reef Program has utilized recycled concrete to establish around 1,100 acres of fish habitat and feeding areas across 47 sites. Marine fisheries officials confirm that new materials are added annually to maintain these crucial underwater ecosystems.
This reuse strategy not only conserves landfill space but also significantly reduces the costs associated with sourcing new materials for reef construction. Such initiatives bolster coastal ecosystems, enhancing local seafood viability and recreational opportunities.
Other regions are adopting similar practices, including Sydney Harbour's use of 3D-printed panels with recycled materials. Coordinated efforts among transportation, marine, and government agencies can redirect demolition debris into valuable resources.
