Sardinia-2025-International-Symposium-on-Waste-Management-Landfill - Session 2

This extended slide deck, presented during the 2025 Sardinia Symposium Focus Sessions, explores how landfills continue to play a vital strategic role in the circular economy.

Co-authored by Egniol’s Michelle Moran, together with Marcus Holden – Holden Environmental, Stewart Davies – Principal Consultant WRC and Robert Gregory – Retired Landfill gas consultant, the presentation charts the evolution from early disposal practices to today’s engineered containment facilities, and explains why modern treatment processes are producing more reactive residuals than ever before.

The slides highlight the challenges of fines, treatment rejects and mixed residual streams, and outline what “responsible future landfill” may look like – including improved monofilling, better monitoring and long-term environmental planning. A valuable resource for anyone shaping landfill strategy, compliance or investment decisions.
