Wood Waste Turned Into Value Added Products: Thermal Plasticization by Benzylation Process
Sawdust is usually considered as waste in wood-using industries. These materials can be converted into value added thermoplastics by means of benzylation. Products can be utilized in different applications where plastics are used. Thermoplasticization process was carried out with benzyl chloride und...
