Re-Use of Borrow Pits: The Dutch Approach to Storing (Contaminated) Dredged Material
Re-Use of Borrow Pits: The Dutch Approach to Storing (Contaminated) Dredged Material

As a result of complex legislation, lack of space and public resistance, cost effective solutions for dredged material, are becoming more and more difficult to find. Re-use of former borrow pits is an attractive option, particularly when it offers opportunities for environmental enhancement.

Dredged Material as a Resource
Dredged Material as a Resource

Contrary to conventional wisdom, most dredged material is clean, natural product and, far from being a waste, can be an important environmental and economic resource, as shown in two case studies: the rehabilitation of a brownfield at Fasiver, Belgium and the creation of a wetland in Wallasea, UK.

Contrary to conventional wisdom, most dredged material should be regarded as a resource, not a waste, and finding new uses for clean dredged material should be a priority.

Mechanical Treatment of Dredged Material. The Malcontenta Plant in the Lagoon of Venic
Mechanical Treatment of Dredged Material. The Malcontenta Plant in the Lagoon of Venice

In an extensive pilot study, contaminated sediment dredged from an industrial channel in Venice has been mechanically treated by dehydration at a purpose-built plant near the harbour.

The Need for Harmonisation in European Practices on the Disposal and Reuse of Dredged Material
The Need for Harmonisation in European Practices on the Disposal and Reuse of Dredged Material

To encourage the beneficial use of dredged material, a harmonised approach - especially for land disposal - is urgently needed.
