wood chips components separation
HIGHER PRODUCTIVITY AND LOWER ENERGY CONSUMPTION
The processing of wood fibers is an important step in the production of paper or in the extraction of lignin, cellulose and hemicellulose. It is therefore crucial to make the process more sustainable, i.e. to reduce energy consumption and the use of chemicals.
Faster and more environmentally friendly
Wet grinding of wood chips with the DYNO-MILL MULTI LAB enables faster and more environmentally friendly extraction of cellulose, hemicellulose and lignin.
Cellulose can be used, for example, in paper production or for higher-quality products such as cellophane or rayon.
Hemicellulose can be used to produce biofuels such as bioethanol, while lignin-based products have proven their worth as fertilizers, sand stabilizers, bioactive compounds and adhesives.
Mechanical force
The separation of the wood into its main components results from the impact of the grinding media.
Faster response
The use of a mechanochemical solution offers numerous advantages, such as improved efficiency and selectivity by simultaneously reducing the use of solvents, process time and thermal energy.
Scalability
The use of a DYNO-MILL enables a continuous process compared to the discontinuous process of chemical depolymerization. The main advantage of a continuous flow is the ability to transfer this process to industrial scale.
Superior environmental performance
The process is less energy-intensive and more efficient than the chemical depolymerization process. Significant advantages have been identified in terms of climate change, land use and photochemical ozone formation.
