The present study investigates the operational conditions for organosolvent pretreatment and hydrolysis of rice straw. Among the different organic acids and organic solvents tested, acetone was found to be most effective based on the fermentable sugar yield. Optimization of process parameters for acetone pretreatment were carried out. The structural changes before and after pretreatment were investigated by scanning electron microscopy, X-ray diffraction and Fourier transform infrared (FTIR) analysis. The X-ray diffraction profile showed that the degree of crystallinity was higher for acetone pretreated biomass than that of the native. FTIR spectrum also exhibited significant difference between the native and pretreated samples. Under optimum pretreatment conditions 0.458 g of reducing sugar was produced per gram of pretreated biomass with a fermentation efficiency of 39%. Optimization of process parameters for hydrolysis such as biomass loading, enzyme loading, surfactant concentration and incubation time was done using Box-Benhken design. The results indicate that acetone pretreated rice straw can be used as a good feed stock for bioethanol production.

This study explores the potential of using underutilized materials from agricultural and forestry systems, such as rice husk, wheat straw, and wood strands, in developing corrugated core sandwich panels as a structural building material. By leveraging the unique properties of these biobased materials within a corrugated geometry, the research presents a novel approach to enhancing the structural performance of such underutilized biobased materials. These biobased materials were used in different lengths to consider the manufacturing feasibility of corrugated panels and the effect of fiber length on their structural performance.

Article Synopsis
- The study analyzed the pyrolysis behaviors of rice husk (RH) and rice straw (RS) using various scientific techniques, revealing distinct stages of pyrolysis for each organic material.
- The activation energies for the different components (pseudo-hemicellulose, pseudo-cellulose, and pseudo-lignin) were calculated, showing varying levels of energy requirement between RH and RS.
- RS demonstrated better pyrolysis performance and produced a greater variety of valuable by-products compared to RH, indicating potential for utilization in agriculture, bioenergy, and chemical sectors.

Lead (Pb) is a highly toxic heavy metal that causes significant health hazards and environmental damage. Thus, the detection and removal of Pb ions in freshwater sources are imperative for safeguarding public health and the environment. Moreover, the transformation of single resources into multiple high-value products is vital for achieving sustainable development goals (SDGs).

This study aimed to identify types of lignin depolymerization products (LDP) and their role in humic substances (HS) formation, and little research has revealed which LDP could participate into HS formation during composting. Therefore, rice straw (RS), peanut straw (PS) and pine needles (PN) were selected for their different lignin structures to qualitatively and quantitative analyze LDP firstly. Qualitative results indicated that RS, PS and PN mainly produced LDP with G-type, common group and dimer structure.
