Wood adhesives play a vital role in the adhesive industry, but in the past, many wood composites were manufactured with significant amounts of toxic components and volatile organic compounds, most of which are petroleum derivatives. The use of renewable, protein-rich elements in adhesive production has been discussed significantly as a promising alternative compared to petroleum-based adhesives in the wood industry. Natural proteins are attracting attention as sustainably sourced and formaldehyde-free adhesives due to their minimal environmental footprint. The present review details the current assessment of formaldehyde-free adhesive systems for particulate composites. Of the viable options for protein feedstocks, agricultural proteins, animal byproduct proteins, algae proteins, and biosolid proteins are some of the many sustainable alternatives for the growing adhesive industry. Improved knowledge of protein properties of a multitude of possible feedstocks for adhesive production is needed to relate the adhesive performance before and after wood bondage. The goal of this review is to present possibilities of applying multiple protein alternatives for adhesive production and to determine the effectiveness in terms of strength, water resistivity, and need for cross-linking.

Sweet potato starch wastewater (SPSW) is an industrial food-processing waste product, which is a significant pollution source due to its high chemical oxygen demand (COD), nitrogen, and phosphorus loads. The influence of hydrolytic acidification (HA) process on C, N, and P as well as other main parameters were evaluated. It is essential to treat these wastewaters with effective methods such as HA, a general pretreatment application. In this study, we investigate the scientific link between the changes of different fractions of C, N, and P with particle size distribution in response to the newly introduced HA process. Results showed that the levels of COD, TN, and TP remained ultimately stable; pH and suspended solids (SSs) decreased obviously. HA process exhibits excellent capability of reducing the larger particulars (with diameter of >5 μm) into smaller ones (with diameter of <0.1 μm). The most significant initial concentration contribution to COD, TN, and TP pollution came from particles and matter with a diameter of >5 μm, at 41.8, 57.3, and 43.5%, respectively. While the most significant contribution to COD, TN, and TP was resulting from micro-molecular size particles (<0.1 μm) after 48 h. The smallest particles (<0.1 μm) were the most dominant contribution to all pollutants measured, with COD, TN, and TP contributions of 63.2, 50.4, and 59.3%, respectively. While the contribution of larger particles (particle size >5 μm) reduced to 10.2, 15.3, and 7.1%, respectively.
