A method of producing a thermally modified and impregnated wooden product is described herein. One or more pieces of wood are thermally modified. The thermally modified wood is formed into a wooden object by hand, tool, machine, a computer numerical controlled machine, or combinations thereof. The wooden object is then impregnated with one or more treatment agents to produce the thermally modified and impregnated wooden product. The wooden object is impregnated by applying pressure or heat while the object is in the presence of the one or more treatment agents. Minimal, if any, deformation of the thermally modified wooden object occurs during impregnation.

The present invention relates to the manufacturing a wood-polymer composite. It is directed to a method for manufacturing such a composite, including the provision of a wood element (1), the impregnation of the wood element with a lactic acid water-based solution (2), and then the thermal treatment of the impregnated wood element (3) at a heating temperature higher than a nominal temperature where the in-situ polymerization of the lactic acid is initiated, in order both to induce the diffusion of the lactic water-based solution acid water-based solution within the impregnated wood element and to initiate the in-situ polymerization of the lactic acid. According to the invention, the thermal treatment (3) includes the acceleration of the increase of the heating temperature and/or the decreasing of the nominal temperature.

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.
