♻️ What if stone waste could become part of the next generation of buildings?
That is exactly what entrepreneur Bassem Okasha is working on in Egypt.
His company B-stone developed ProTile: façade panels made from recycled granite and marble waste, combining a natural look with thermal, moisture and sound insulation.
In collaboration with PUM expert Henri van Muijden, B-stone worked on the next phase of growth. Together, they strengthened the business plan, market approach and organisational structure needed to bring ProTile successfully to market.
The progress is already visible. ProTile is fully tested and ready for market entry, B-stone is building its first commercial pipeline, and in June 2026 the product won first place in the MVP Track of the 7th Tatweer Misr Innovation Competition.
By combining practical expertise with entrepreneurship, B-stone is creating new business opportunities from an environmental challenge.
