Research Interests and Expertise

Leaching assessment and methods (including waste form performance), environmental performance of cementitious materials, (contaminated) soil, sludge and waste, nuclear and chemical waste, environmental remediation, management of residuals from energy production and waste to energy facilities, multi-element geochemical modeling of cementitious products, soil, sludge and waste systems. Relationship between laboratory, lysimeter and field scale testing in combination with geochemical modeling as basis for long term prediction of release.

Brief Biography

Dr. van der Sloot held different positions in the Netherlands Energy Research Foundation (ECN, Petten, The Netherlands) until December 2009. After retiring from ECN he started his private consultancy.

He has been involved in standardization of leaching tests for waste, soil and construction products at national and international level (CEN, ISO, US EPA). He is Associate editor for Waste Management. He is a board member of the International Waste Working Group (IWWG) and active in developing a decision support tool for environmental impact assessment (LeachXS) in cooperation with ECN (Petten, The Netherlands), Vanderbilt University (Nashville, USA) and DHI (Hørsholm, Denmark)

In cooperation with partners in the Cement Barriers Partnership under the sponsorship of the Consortium for Risk Evaluation with Stakeholder Participation (CRESP) and coordination by Vanderbilt University, he has been involved in nuclear waste studies with the emphasis on testing and modeling of the source term for contaminant release from disposal facilities to soil and groundwater.

His research and his standardization activities in collaboration with Vanderbilt University on leaching of contaminants from wastes and construction materials has been providing the foundation for environmental regulation of these materials by the Netherlands Ministry of Environment , at USEPA and the European Union’s Directorate General for the Environment.
