Solvothermal liquefaction as a pro-ecological method of wood-like waste management

The main scientific goal of the project is to describe the influence of the liquefaction process parameters and the composition of the reaction mixture on the structure and properties of the obtained polyols. The project includes several systematic studies regarding the structure and properties of the obtained products. The work assumes the use of a variety of different homogeneous catalysts as well as modern heterogeneous catalysts which can be easily separated from polyols. This can eliminate the neutralization process, which is necessary in the case of using sulphuric acid. Moreover, searching for more efficient catalysts that can be recycled and used multiple times fits into the trend of “Green Chemistry”.The influence of the type, structure, amount of catalyst on the process, and properties of the obtained materials will be determined. Moreover, the impact of the regeneration process parameters of selected catalysts as well as the number of catalysis cycles on the process efficiency and product properties will be investigated. Another key aspect is determining the impact of the type and structure of the solvent/mixture of solvents on the catalyst activity, process parameters, and properties of polyol. In this project, it is planned to use solvents with different molecular weights and functionality. The impact of the waste type, the level of fragmentation, and the amount of waste on process parameters and material properties will be determined. The influence of reaction time, pressure, temperature, and inert gas flow on the process and properties of the obtained product will be determined. Determining the impact of the basic parameters of this process will allow us to fully define the studied process, as well as determine its ability to increase the scale of the project. The project aims to introduce the know-how which I gathered working in my previous scientific work and cooperation with the industry. This research project will be linked to the future application of wood-like post-use and post-production waste from the wood-like panels such as chipboard, OSB, and MDF panels. Moreover, this type of waste management is preferred by international restrictions and is also an alternative to the current energy recovery of wood waste.

Towards sustainable catalyst-free biomass-based polyurethane-wood composites (PU-WC): From valorization and liquefaction to future generation of biocomposites
Publication
- JOURNAL OF CLEANER PRODUCTION - Year 2024
A substantial aspect of materials engineering lies in the responsible process of designing polymer-based materials. Due to environmental pollution, excessive consumption of natural resources, and increasing environmental awareness of society, there is a massive need for polyurethane (PU) materials with reduced environmental impact. To date, research on catalyst-free polyurethane-wood composites (PU-WC) has demonstrated a huge potential...

A novel approach in wood waste utilization for manufacturing of catalyst-free polyurethane-wood composites (PU-WC)
Publication
- Sustainable Materials and Technologies - Year 2023
In recent decades, due to the increase in environmental awareness and noticeable environmental degradation, the area of wood waste management has attracted increasing attention. The purpose of this study is to develop a new type of highly filled polyurethane wood-composite (PU-WC) by the utilization of large amount of wood wastes without addition of a catalyst. Although wood-plastic composites (WPCs) are widely known, there is...

Polyurethane-wood composites (PU-WC) as a method of wood waste management
Publication
- Year 2023
In recent years, due to the progressive environmental degradation and increase of environmental awareness, the sustainability of production systems in wood processing, the wood industry, and wood waste management is a crucial issue for European industry and society. Consequently, the problem of generating wood-like waste and the associated risks has become an increasingly noticeable challenge for science. Although various methods...
