Capturing the arsenic fraction of CCA treated waste wood in the solid instead of in the gas phase during pyrolysis

Article publication date: 1 October 2004
Recycling of preservative‐treated waste wood can be an environmental problem due to toxic elements being emitted into the environment. Pyrolyzing CCA‐treated wood at low temperature without any oxidizing agent is applied to capture the arsenic fraction in the solid residue. The influence of well‐defined process parameters such as pyrolysis temperature, time and heating rate are studied. Arsenic contents in the gas phase were measured by a wet chemical method while structural analysis of the arsenic reaction products was determined with Transmission Electron Microscopy.
