Purpose of Review

For the past few decades, consumers have increasingly demanded biodegradable, petroleum-free, and safe products for the environment, humans, and animals, with improved performance. In terms of energy consumption, modern society has progressively sought to reduce fossil fuel utilization and greenhouse gas emissions. This review presents and discusses the possibilities of using biomass residues that are derived from forest operations and wood manufacturing to produce biofuels and biomaterials as sustainable alternatives that could boost the development of renewable technologies and bio-economy.

Recent Findings

Forest biomass residues are composed primarily of cellulose, hemicellulose, and lignin in varying proportions depending upon the species. Residues from forest operations have heterogeneous compositions due to the presence of branches, foliage, tree tops, and bark, compared with those derived from wood manufacturing industries. Several technological approaches have been developed to add value to forest biomass residues through their conversion to biomaterials such as wood-based composite panels, wood-plastic composites, wood pellets, and biofuels, such as biochar, bio-oil, syngas (thermochemical approach), and biogas (biochemical approach).

Summary

Forest biomass residues are valuable lignocellulosic materials, but research is still required regarding their conversion into value-added products given their heterogeneous compositions and varied physicochemical properties. Obstacles such as transportation costs and their complex structural and chemical mechanisms that resist decomposition need to be better overcome in developing high-quality and economically viable biofuels and biomaterials. In contrast, wood-based panels, composites, pellets, and biofuels produced by the wood manufacturing industries exhibit superior properties and characteristics for commercialization. Recent studies regarding valorization of forest biomass residues are a welcome recognition of the need to transition to a sustainable economy, and a definitive strategy for achieving objectives that have been set for reducing greenhouse gas emissions.

森林经营和木材制造过程中生物质残留物的价值评估提出了广泛的可持续性和创新性可能性

审查目的

在过去的几十年中，消费者对性能，性能提高的环境，人类和动物的可生物降解，无石油和安全产品的需求日益增长。在能源消耗方面，现代社会逐渐寻求减少化石燃料的利用和温室气体的排放。这篇评论提出并讨论了使用源自森林经营和木材制造的生物质残渣来生产生物燃料和生物材料作为可持续替代品的可能性，这可以促进可再生技术和生物经济的发展。

最近的发现

森林生物质残留物主要由纤维素，半纤维素和木质素组成，取决于物种。与木材生产行业相比，由于存在树枝，树叶，树梢和树皮，来自森林经营的残渣具有异质成分。已经开发了几种技术方法，通过将其转化为生物材料（例如，木质复合板，木塑复合材料，木质颗粒和生物燃料，例如生物炭，生物油，合成气）来增加森林生物质残留的价值（热化学方法） ，以及沼气（生物化学方法）。

概要

森林生物质残留物是有价值的木质纤维素材料，但鉴于其异质组成和不同的理化特性，仍需要对其转化为增值产品进行研究。在开发高质量且经济上可行的生物燃料和生物材料时，需要更好地克服运输成本以及阻碍其分解的复杂结构和化学机制等障碍。相反，由木材制造工业生产的人造板，复合材料，颗粒和生物燃料表现出优异的性能和商业化特性。最近有关森林生物量残留物增值的研究令人欢迎地认识到需要向可持续经济过渡，
