This study evaluates the mechanical energy consumption involved in producing wood-plastic composites (WPC) using Scots pine () and a acrylonitrile-butadiene-styrene terpolymer (ABS) thermoplastic. The research examines the effects of Hot Water Extraction (HWE) on the properties of biomass and its application in biocomposite production. Two fractions, (0-1 mm) and (1-4 mm), were analyzed with and without HWE during compaction. The energy requirements and material performance were assessed through moisture content control, ash content determination, and compaction testing. The results show that HWE significantly improves the physical and chemical properties of , increasing its suitability for WPC production. The HWE-treated samples consumed less energy and exhibited a higher density compared to the untreated materials. Statistical analysis validated the reliability of the methodology and revealed significant differences in the energy efficiency and material compatibility between treated and untreated samples. This study highlights the potential use of and ABS for renewable bio-composite production, underlining the critical role of HWE in enhancing the properties of lignocellulosic materials. The findings contribute to developing energy-efficient industrial processes aligning with circular economy objectives.
本研究评估了使用苏格兰松（Pinus sylvestris）和丙烯腈-丁二烯-苯乙烯三元共聚物（ABS）热塑性塑料生产木塑复合材料（WPC）所涉及的机械能消耗。该研究考察了热水萃取（HWE）对生物质性能的影响及其在生物复合材料生产中的应用。在压实过程中，对两个粒径级分，即0-1毫米和1-4毫米的生物质，分别在有无热水萃取处理的情况下进行了分析。通过控制水分含量、测定灰分含量和进行压实测试来评估能量需求和材料性能。结果表明，热水萃取显著改善了生物质的物理和化学性质，提高了其用于生产木塑复合材料的适用性。与未处理材料相比，经热水萃取处理的样品消耗的能量更少，且表现出更高的密度。统计分析验证了该方法的可靠性，并揭示了处理和未处理样品在能源效率和材料相容性方面的显著差异。本研究强调了使用苏格兰松和ABS生产可再生生物复合材料的潜力，突显了热水萃取在增强木质纤维素材料性能方面的关键作用。这些发现有助于开发符合循环经济目标的节能工业工艺。
