TLDR
In this article, the main results of research work on chemical and thermal treatment techniques from a special programme, subsidised by the Dutch government, are described, where three processes were selected as potential remediation processes based on their clean-up results (> 99% removal of specific contaminants): solvent extraction, wet air oxidation and thermal desorption.About:

Journal ArticleDOI
An evaluation of technologies for the heavy metal remediation of dredged sediments.
TL;DR: Sediments dewatering is frequently necessary after dredging to remediate and treat contaminants and few remediation techniques have been commercially used for sediments, but there exists significant demand for further development.
Journal ArticleDOI
Aging and temperature effects on DOC and elemental release from a metal contaminated soil.
TL;DR: Total soluble metal release (ICP) paralleled the behavior of DOC, increasing with both time and temperature, and confirming the importance of soil organic matter (SOM) in metal retention, and variations in the relative molecular size fractions present within the DOC pool produced by increased time andTemperature may influence the element-DOC complexes present in solution and their behavior in soil environments.
Journal ArticleDOI
Immobilization of Heavy Metals by Co-pyrolysis of Contaminated Soil with Woody Biomass
TL;DR: In this article, the authors investigated the potential application of pyrolysis treatment to a mixture of woody biomass and a metal-contaminated soil as an alternative eco-friendly option to stabilize metals in soils.
Journal ArticleDOI
Synthesis of Zeolite From Thermally Treated Sediment
TL;DR: By fusion with sodium hydroxide followed by a hydrothermal reaction, a thermally treated sediment was successively converted into zeolites Na−P1, Na−X, hydroxysodalite, F Linde A, and faujasite as discussed by the authors.

TL;DR: Oxygen-free atmosphere can prevent formation of dioxin during thermal process thus generating clean solid residues and confirmed that some complex reactions do occur to form PCDD/Fs and PCBs from 800 to 400 degrees C in the presence of oxygen.
