The use of low-cost agricultural and forestry waste for the preparation modified phenolic foam (MPF) has attracted widespread attention shown promising prospects. This study proposes a novel method producing MPF using pine sawdust. full components wood powder its liquefied products were used as raw materials, resin was with silane coupling agent (KH560), triethylene glycol (TEG), nylon 66 (PA66). Subsequently, three MPFs successfully fabricated transplanted core foaming technique, their material properties subsequently investigated. results showed that all exhibited excellent compressive strength flame retardancy, ranging from 5.93 MPa to 12.22 oxygen index values between 36.2% 41.5%. In terms water resistance, significantly outperformed traditional (PF); in particular, addition 4% KH560 PA66 reduced absorption rate low 2.5%. Furthermore, powdering thermal conductivity reduced, chalking rates decreasing by 28.57% 50%. research presents preparing agroforestry partial replacement phenol. approach achieves high-value utilization sawdust while maintaining performance MPF, thus broadening avenues production.

Biochar, produced from biomass, has become recognized as a sustainable soil amendment that the potential to improve quality and agricultural production. This review focuses on production processes properties of biochar derived different types including synergistic interactions between microorganisms, emphasizing their influence overall crop production, particularly in cultivation Brassica crops. It additionally addresses benefits limitations microbial application. Biomass is renewable abundant resource can be converted through pyrolysis into biochar, which high porosity, surface functionalities, capacity retain nutrients. These characteristics provide optimal conditions for beneficial communities increase nutrient cycling, reduce pathogens, structure. The information indicates use crops result improved plant growth, yield, uptake, stress mitigation. includes about such pH, elemental composition, ash content, affected by biomass used well like temperature. Understanding these variables essential optimizing use. Moreover, microbes emphasizes importance with constraints. Therefore, agriculture methods possibly achieved integrating management measurements, resulting higher productivity adaptability or other systems. aims comprehensive understanding biochar’s role supporting farming its address contemporary challenges.

The rational use of wood waste allows the saving forest resources and contributes to reduction greenhouse effect. Three types were used in this work: packaging (W), demolition furniture construction (PLY), door production (DW). work performed an analysis granulometric composition assessed size, shape, particles. particle size was range 0–20 mm, but quantitative proportion particles different sizes nature shape different. All thermochemically treated reduce amount dust soluble increase surface roughness ensure better adhesion parameters with binder. binder biopolyurethane. Engineered composites (EWC) formed from biopolyurethane a 50:50 ratio evaluate compressive bending strength. strength values showed that all wastes suitable for forming composites, affected magnitude these values. highest stress 11.7 MPa obtained using 0–5 mm PLY waste, while lowest 5.2 W waste. In case, not only also density composite. composite densities 84.1% variation total determined by sample fraction, length-width ratio, angularity sharpness 15.9% other factors evaluated. For flexural strength, did show clear tendency, ranged 7.2 11.5 MPa. thermochemical treatment method had no or slight effect on characteristics engineered
