Forest residues serve various purposes globally. The inclusion of forest residues enhances the mechanical properties of wooden panels by up to 50%. Briquettes produced from branches exhibit a longer burning time compared to those made from wood sourced from tree trunks, attributed to the higher lignin content, which augments frictional and compressive strength. Biochar, distinguished by its porous and highly carbonated nature, acts as a unique adsorbent. It enhances soil fertility, water retention, pH levels, and organic matter, while mitigating nutrient leaching and the infiltration of organic and inorganic pollutants. Optimal biochar production efficiency is achieved at lower temperatures with elevated lignin content. The production sources for biochar include plants and fertilizers. Biochar derived from plants can be utilized as a soil conditioner, while biochar derived from manure can function as both a soil conditioner and fertilizer due to the release of nutrients. However, forest residues are not as effective for biogas production; the methane yield from hardwood residues is several times greater than that from softwood residues. The production of ethanol or butanol is influenced by the organic materials to microorganisms ratio. The high cost of hydrolytic enzymes diminishes the appeal of the enzymatic hydrolysis process, despite its significant advantages. Forest residues have the potential to serve as substrates for the growth of diverse insects. Furthermore, cultivating edible mushrooms on these substrates derived from forest agricultural residues can contribute to sustainable forest management, environmental protection, and global food security in the future.
