At the P3 Rakietowa development in Wrocław, general contractor Atlas Ward Polska demonstrated circular construction by reusing 81.7% of all excavated soil directly on site. The project generated 7,659 m³ of material from building and road excavations. Instead of treating this as waste, 6,259 m³ was cleaned, conditioned and stabilised to meet structural requirements, then reused for 4,405 m³ of backfilling and 1,854 m³ of embankments.
Only 18.3% of material required external handling. This approach significantly reduced the need for virgin aggregates and avoided over 620 truck movements, cutting transport emissions and local disruption.
The project shows how excavated soil can become a load-bearing construction resource, proving that circular earthworks are both technically viable and environmentally impactful when embedded through strong contractor collaboration.
