“…The comparison of the frass and the other fiber materials' chemical compositions is shown in Table 2 . The nonwood fibers ( Pennisetum alopecuroides 30 , cornstalk 31 , rice straw 32 and wheat straw 17 ) in Table 2 have been recorded in the application of pulping and cattle raising. According to the study's results, it was found that the holocellulose and α-cellulose content in the frass is higher, while the acid-insoluble lignin content is lower.…”

Cattle dung treatments in Taiwan have developed a process called Black soldier fly larvae (BSFL) treatment, which can digest cow dung and generate the frass (larvae drops), the residue fiber in cow dung. This study aims to assess frass for its potential in pulp and papermaking, considering its chemical compositions, appearance, and fiber morphology, and also evaluate its suitability for pulping by soda method to create added value. The frass exhibits favorable material properties for pulping and papermaking, including a high holocellulose (67.37%) and α-cellulose (48.00%) content, along with a lower ash content (4.61%); the microstructure and surface mesoporous pores benefit for pulping; and the nonwood-fiber-like fiber morphology. The pulping experiment shows that 7% NaOH and 75 min of pulping conditions result in proper disintegration of fiber, and the highest accepts ratio (34.06%). The NaOH causes fiber disintegration during pulping, resulting in a higher strength property of the handsheet. The frass pulp blended with TOCC can achieve the ring crush index standards required for cardboard products. In summary, the frass from BSFL treatment of cattle dung can be utilized in pulp and papermaking to enhance circular utilization value.

Taiwan generates 4,800 tons of cow dung daily, necessitating the development of a novel circular utilization process to increase the recycling value of cow dung. The black soldier fly larvae (BSFL) treatment can digest the cow dung, and the frass (larvae drops) is the residue fibers in cow dung The study aims to assess the feasibility of utilizing the frass in pulp and papermaking by analyzing frass chemical composition, appearance, fiber morphology, and estimating its suitability for soda pulping, with the goal of developing value-added circular utilization process for frass. The chemical composition of the frass shows the high content of holocellulose, α-cellulose and the lower content of ash, which indicates the potential of pulping application. The fiber structure and mesoporous pores of the crude fibers in frass are beneficial for the pulping reaction. The fiber morphology of the frass is similar to non-wood fibers (pulping raw materials), which indicates the feasibility of fiber application. After the soda pulping experiment, pulping the frass with 7% NaOH for 75 minutes results in efficient fiber disintegration with a lesser degradation, which is the highest accepts ratio in the study. The NaOH cause the better disintegration of fibers and the better formation structure of the handsheet. The frass pulp blended with TOCC can enhance the ring crush index and bulk of handsheet. In the meantime, the mixed pulp (frass-TOCC) can achieve the ring crush index and bulk standards required for cardboard, without the chemical additives. To sum up, the fiber-like frass from BSFL treatment of cattle dung can be utilized in pulp and papermaking to enhance circular utilization value.

“…The opportunities for CS valorization are expanded by the contemporary management strategies (CE, ZW). Nowadays, CS residues may be recycled to produce cellulose/epoxy resin composites [23], cellulose nanofibrils [24], cellulose composites [25], carbonaceous composite adsorbents [19], levulinic acid and biocarbon electrode material [26], second-generation bioethanol [27], biomethane [28], chemical pulp [29] and various biomaterials (plastics, hydrogels, fibers, composites) [30]. The use of agricultural waste biomass as fillers in different bio-composites [31], bio-plastics, tires [32], and other reinforced polymers [33,34] is one of the most promising directions to its conversion into value-added goods [34].…”

The present study deals with the valorization of corn stalks in an integrated processing strategy targeting two products: extracted hemicelluloses (HC) and papermaking fibers. Preliminary trials were conducted to assess the individual or the combined effects of biomass treatment on the quality of the obtained hemicelluloses and papermaking fibers. Depending on the hot alkaline extraction (HAE) conditions, the extracted HC had a xylan content between 44–63%. The xylan removal yield ranged between 19–35%. The recovery of HC from the extraction liquor and final black liquor was significantly affected by process conditions. The experimental approach continued with the study of HAE conditions on the obtained paper’s mechanical properties. The optimization approach considered conserving paper strength properties while achieving an equilibrium with the highest possible HC extraction yield. The optimal values are sodium hydroxide concentration (1%), process time (33 min), and temperature (100 °C). The xylan content in the separated HC sample was ~55%. An extended extraction of HC from the resulting pulp under hot alkaline conditions with 5% NaOH was performed to prove the HC influence on paper strength. The xylan content in HC samples was 65%. The consequence of xylan content reduction in pulp leads to 30–50% mechanical strength loss.
