Recycled Wood(再生木材)研究综述
Recycled Wood 再生木材 - Furthermore, in the event of scarcity involving timber in the European Union, recycled wood and post-harvest residues could replace conventional raw materials in wood-based composites such as particleboards and chipboards. [1] Finally, a life cycle assessment of particleboards made from recycled wood and bio-resins reveals that all scenarios for the production of particleboards in a CE approach are environmentally benign alternatives, reducing up to 95% of the environmental impacts to human toxicity, abiotic depletion and other impacts compared to the traditional and linear scenario. [2] Purpose Using the effective approaches for modifying the recycled wood as a novel bulky agent improves the quality of soil amendment. [3] However, current legislation and wood waste recycling processes need to be improved in order to maximize the volumes that can be reused and to upgrade the properties of the recycled wood. [4] This study is focused on investigating the use of recycled wood, paper, cardboard, metal, glass, mineral wool, gypsum, concrete, and ceramics as raw components for composite materials. [5] In this study, however, CLT fabricated using recycled wood was explored for possible utilization in wood structures. [6] Combustion of recycled fuels as well as incineration of waste are excellent means to generate heat and to convert redundant objects and spent items to a form that readily lends itself to sampling and characterization, Many harmful substances may be efficiently destroyed in the process and others, such as heavy metals, may become concentrated, Consequently, it is necessary that any decision on the future fate of an ash volume be based on the content (as checked by chemical analysis) as well as on the availability (as checked by leach tests) of possibly hazardous substances, However, in the case of heavy metals in ash, an assessment based on content and by direct application of the existing legislation is essentially impossible to carry out in practice, The reason is that the chemical form is very complex and cannot readily be associated with the substances appearing in the data bases on hazardousness of chemical substances, Another major concern is that the assessments need be valid for very long times while the time spans available for measurements and experiments is very short in comparison, A methodology to cope with these issues has been developed and applied in a project on utilization of ash in covers, including seals, for landfills, At present, four hectares of old domestic waste have been protected at Telge Atervinning AB (Telge Recycling Plant) in a full scale test and the plans for the subsequent step include another eleven hectares, The ash originates from recycled wood based fuel (also containing paper and plastics) combusted for district heating purposes at Soderenergi AB (lgelstaverket), It was found that it is possible to identify reference substances which appear in the data bases on hazardousness and which represent the actual chemical form of the various elements in a conservative manner, In order for such an approach to be valid and robust, it was found necessary that a knowledge base on chemical composition and speciation be developed and compiled, The knowledge base is also used for predictions of the future properties and behaviour of the ash in terms of content and availability of hazardous substances as well as and permeability, 135 https://doi. [7] The typical biofibre sources for bioplastics include cotton, flax or hemp, recycled wood, waste paper, crop processing byproducts, etc. [8] 07 hag/m2, largely due to the use of recycled wood. [9] recycled woods, combustible municipal solid waste, and industrial and commercial wastes. [10] Recycled wood of two grades (A and B) and spruce were converted on bench (100 o. [11]此外，在欧盟木材稀缺的情况下，回收木材和收获后残留物可以替代刨花板和刨花板等木质复合材料中的传统原材料。 [1] 最后，对由再生木材和生物树脂制成的刨花板的生命周期评估表明，采用 CE 方法生产刨花板的所有方案都是对环境无害的替代方案，可减少高达 95% 的环境影响，包括人类毒性、非生物消耗和与传统和线性情景相比的其他影响。 [2] 目的利用再生木材作为新型膨松剂改性的有效途径，提高土壤改良剂的质量。 [3] 然而，目前的立法和木材废料回收流程需要改进，以最大限度地提高可重复使用的数量并提升回收木材的性能。 [4] 这项研究的重点是调查使用再生木材、纸张、纸板、金属、玻璃、矿棉、石膏、混凝土和陶瓷作为复合材料的原材料。 [5] 然而，在这项研究中，探索了使用回收木材制造的 CLT 是否可能用于木结构。 [6] 再生燃料的燃烧以及废物的焚烧是产生热量并将多余的物体和用过的物品转化为易于取样和表征的形式的极好方法，许多有害物质可以在过程和其他过程中被有效地销毁，例如作为重金属，可能会变得浓缩，因此，任何关于灰量未来命运的决定都必须基于含量（通过化学分析检查）以及可用性（通过浸出测试检查）可能有害的物质，但就灰分中的重金属而言，基于含量和直接应用现行法规的评估在实践中基本上是不可能进行的，原因是化学形式非常复杂，不容易与出现在化学物质危害性数据库中的物质相关联，另一个主要问题是评估需要对很长的时间，而可用于测量和实验的时间跨度相比之下非常短，已经开发出一种方法来解决这些问题，并将其应用于垃圾填埋场的覆盖物（包括密封件）中的灰利用项目，目前，四个Telge Atervinning AB（Telge 回收厂）已对公顷的旧生活垃圾进行全面测试，后续步骤的计划包括另外 11 公顷，灰烬来自燃烧的再生木基燃料（也包含纸和塑料）用于 Soderenergi AB (lgelstaverket) 的区域供热，发现可以识别出现在危险性数据库中并以保守方式代表各种元素的实际化学形式的参考物质，为了这样一种有效且稳健的方法，发现有必要开发和编译有关化学成分和物种形成的知识库, 该知识库还用于预测灰烬在有害物质的含量和可用性以及渗透性方面的未来特性和行为，135 https://doi。 [7] 生物塑料的典型生物纤维来源包括棉花、亚麻或大麻、再生木材、废纸、农作物加工副产品等。 [8] 07hag/m2，主要是由于使用了再生木材。 [9] 回收木材、可燃城市固体废物以及工业和商业废物。 [10] 两种等级（A 和 B）和云杉的再生木材在工作台上（100 o.

This work presents a study on the preparation of recycled wood fibre using different types of grinding equipment. [1] In this study, different combinations of recycled wood fibre and rubber powder were added in AAC to improve its performance and reduce the negative environmental impacts of solid waste. [2] This paper reports on the hygrothermal behaviour of a new bio-based composite building material, based on recycled wood fibres used as eco-aggregate within a cementitious matrix.
