Lecturer: Dr. Robert Nemeth PhD.
The market share of modified wood material is growing intensively. There are several applied industrial processes and even more newly developed technologies just before the industrial application.
In the frame of the subject the students get acquainted with the purposes of the modification of the wood material. In order to offer a better understanding of the processes applied in the industry the theoretical background is discussed as well. In the lectures and laboratory exercises the modification techniques with oil, heat, steam, external mechanical forces, irradiation and biological treatments will be discussed in detail. Furthermore the effects of the treatments on the wood properties will be discussed, with special attention to density, strength properties, sorption properties, dimensional stability, equilibrium moisture content, natural durability, colour and technological properties (glue ability, etc). The effect of the anatomical properties on the success of the modification treatment is included in the subject as well. Additionally the possible uses of the modified wood will be discussed considering the market developments: plastics gain market share at the expense of wood.
The study program involves lectures and exercises in the laboratory.

Controlling the wood dust hazards
Lecturer: Endre Magoss PhD.
Proper dust extraction systems and air filtering systems are important in every woodworking workshop. Repeated exposure to wood dust can cause different type of diseases.
