I would consider ceramic tile flooring with minimal grout lines. You can find many options with recycled content.
You may want to consider Crossville Ceramics that are:
- made in the USA,
- Floorscore certified and
- have an innovative "tile take-back" program.
The best part is that ceramic tiles are non-absorptive and easy to maintain.
