The present method applies Pulsed electric fields adding additional control variables for the extraction of target organic compounds from plant material. A current method of extraction of target Cannabaceae plants during processing provides methods to accelerate drying and extraction of these oil rich plants where the pre-removal of water is beneficial aiding in decreased process times. The methods include applying electric fields to the plant material to accelerate the dehydration, and the extraction of target organic compounds.

Disclosed herein is a method of remediating chromated copper arsenate (CCA) treated timber. Particularly, the method comprises contacting the CCA timber with an oxidative solvent and an acidic solvent which provides remediated timber and a variety of extracts containing amongst other things the metals of concern. One or more of the steps is conducted using continuous counter current extraction (CCE).

An apparatus and method for high pressure treatment of bulk material by extraction and/or impregnation may involve high pressure treating bulk material in a high pressure treatment volume of a pressure vessel apparatus at a high pressure level, especially high pressure in the range from 40 to 1000 bar. The method comprises at least the three following step sequences that are each controllable individually: pressurization, high pressure treatment, and depressurization. The high pressure treatment is performed in a continuous manner in the high pressure treatment volume. The high pressure treatment volume or the entire pressure vessel apparatus is in a fixed arrangement during the high pressure treatment. The continuity of the high pressure treatment is ensured solely by means of the high pressure treatment volume. This especially enables engineering optimization of high pressure treatment processes, for example extraction.
