   Abstract : There is growing demand for a more efficient use of polymers that originate from renewable feedstocks due to the depleting supply of fossil fuels, based on economic and environmental reasons. As a result, lignin has attracted renewed interest as a resource for various bioproducts. READ MORE

6. 4. Agro-industry feedstock and side stream materials for wood panel manufacturing

   Author : Nicolas Neitzel; Stergios Adamopoulos; Reza Hosseinpourpia; Thomas Walter; Heiko Thömen; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Wood-based panels are indispensable in many areas, such as the construction industry and furniture production. The intensified demand for renewable materials, rising wood prices and increasing protection zones of forest areas make the wood panel industry consider alternative raw materials. READ MORE

7. 5. Spectroscopic and Microscopic X-ray Fluorescence Analysis for Environmental and Industrial Applications

   Author : Siwen An; Börje Norlin; Göran Thungström; David Krapohl; Yuying Huang; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Heavy metals are well-known environmental pollutants due to its potential impact on associated ecosystems and human health. Thus, it is important to monitor the levels of heavy metals in the environment. X-ray fluorescence (XRF) analysis is a powerful and effective screening tool in measuring the concentration of multi-elements simultaneously. READ MORE
