Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising an aqueous alkaline copper-containing solution comprising copper tetraammine carbonate; and exposing the cellulosic material provided thereby to carbon dioxide to provide treated cellulosic material.

A system and its use for treatment of freight in a vacuum, having a chamber 1 for receiving a loaded container 9 having an external length CLa, an external width CBa and an external height CHa, wherein the chamber 1 has two side walls 11, 12 arranged opposite to a bottom 13 and top 14 and arranged opposite to a front wall 15 and back wall 16, and wherein a direction system XYZ is at right angles; and a conveying element 2 for parking and moving a container 9 relative to chamber 1 from a first position P1 outside the chamber 1 into a second position P2 inside the chamber 1; and a driving device 8 for moving between the first position P1 and the second position P2.

A protectant and sealant solution and method of use thereof, configured to protect wood from premature decay when disposed in contact with the earth. The solution is composed of processed hemp oil which is mixed with bio-diesel and other oils to form the protectant solution. The wood is then impregnated with the solution via pressure treatment within a retort cylinder. The solution is configured to protect utility poles and other wooden construction members which are known for prolonged contact with soil. The solution is designed as a safe replacement for pentachlorophenol solutions which have been found to be harmful to the soil and water table.

A process for the thermal-chemical modification treatment of wood is described, in which such a modification is obtained through multiple chemical reactions of the substances comprising the wood structure generated by exposing the wood to temperatures at which the pyrolysis phenomenon begins, i.e., in the range of 180 C.-240 C., in a vacuum autoclave-cell while always maintaining the internal pressure lower than the atmospheric pressure, in a range of values of 70-350 mBar of absolute pressure, consisting in the steps of pre-heating, actual heat treatment, and cooling of a wood mass.

Toothpicks infused with additives and methods for infusing those toothpicks are described.
