Innovative Eco-Technologies to Reduce Emissions in the Manufacturing Processes of Special Wood Products

Abstract

In the processes of surface treatment of specific wood products, a variety of coatings are used, which even in small-scale production represent the presence of certain hazardous chemicals. Risk substances from the group of volatile organic compounds (VOC) in surface treatment processes of wood products constitute a large number of contaminants that negatively affect both the working and the environment. These are, in particular, still used solvent-based coatings (CN, PUR, PES). The presence of solvents, thinners for consistency and viscosity treatment in coating processes and curing of these coatings a serious environmental risk even in small surface treatment operations in the production of special wood products (sporting goods, musical instruments, artistic and solitary wood articles). To solve the suggested problem, it is necessary to analysed all aspects that could reduce the production of these hazardous chemical substances. We have proposed a variety of eco-technical separation devices: using adsorption technologies with (or without) regeneration of adsorbent for effective capturing of pollutant emissions. Our research has been comparing the effectiveness of capture of pollutants (VOC) in small scale model plant surface treatments of special wood products.
