“…Hence, high-temperature aerobic composting is now widely used. [3,5,10,32,34] However, because of the short processing time and insufficient breakdown, high-temperature fast composting necessitates further processing of the product. The vermiculation process, which uses earthworms and bacteria to break down organic waste, can overcome this problem.…”

“…[1,5,13] Nevertheless, traditional simple TCMR disposal methods involving landfilling, incineration, and stacking would eventually result in serious environ-mental problems and resource waste. [10][11][12][13][14] Indeed, toxic substances in the TCMR can be transferred into the atmosphere, water, and soil via ecological cycles, harming the environment and endangering human health. Consequently, due to reducing environmental pollution and improving resource utilization, classifying and efficiently utilizing the residue of TCM has become the future research direction of the TCM industry.…”

Chinese medicine is widely employed in illness prevention and treatment. In recent years, the increased demand for Chinese medicine resources has resulted in a large quantity of waste created during industrialization. However, traditional methods for treating herbal residues, including burning, stacking, and burying, can cause significant environmental damage and resource waste. Furthermore, these application approaches have a low level of resource utilization and a low degree of utilization. Therefore, developing a classification management system is a necessary precondition for reusing Chinese herb residues for medicinal, feed, fertilizer, and energy resource reuse. This paper reviews the potential applications of Chinese herb residues in the extraction of active resources, composting, feed addition, bioethanol preparation, and pyrolysis to biochar, bio‐oil, and fuel gas. Overall, this work provides a foundation for further investigation into the high‐value usage model and resource reuse pathway of Chinese herb residues.

“…In China, approximately 70 million tons of herbal residues are produced each year, but a large amount of them are discarded directly, which causes serious environmental pollution such as groundwater pollution, unpleasant smells, or greenhouse gases emissions (Zhang et al, 2017;Wang et al, 2021). However, herbal medicine residues still contain great nutrient content and natural bioactive bioactivity such as cellulose, proteins, flavonoids, polysaccharides, organic acids, and so on (Su et al, 2018;Ni et al, 2020).…”

“…Herbal residues are a kind of by-product produced after the extraction process from medicinal plant materials (Zhou et al, 2018;Wang et al, 2021). To date, there are approximately 1,600 kinds of Chinese medicinal herbs used in China (Zhou et al, 2018).…”

This study aimed to investigate the influence of herbal residues on the fermentation quality and ruminal fermentation of paper mulberry silage. Clove, mint, and purple perilla residues were used as additives. Silage treatments were designed as control (no additives), 5% of clove, 5% of mint, and 5% of purple perilla. After 21 and 75 days of fermentation, the fermentation characteristics, bacterial communities, and ruminal greenhouse gas emissions in vitro incubation of paper mulberry were analyzed. The results showed that the used herbal residues could reduce the protein losses in paper mulberry silage based on the lower contents of ammoniacal nitrogen and nonprotein nitrogen. Compared with control, higher lactic acid and propionic acid contents were observed in the silages treated with mint and purple perilla but with a higher acetic acid content in clove treatment. Real-time sequencing technology (single-molecule real-time) revealed that Lactobacillus was the dominant bacteria in all silages at the genus level, whereas the bacterial abundance in the treated silages differed greatly from control at the species level. Lactobacillus hammesii abundance was the highest in control, whereas Lactobacillus acetotolerans was the first predominant in the treated silages. All the additives enhanced the digestibility of in vitro dry matter significantly. However, purple perilla decreased the production of total gas, methane, and carbon dioxide. The findings discussed earlier suggested that herbal residues have potential effects in improving fermentation quality, reducing protein loss, and modulating greenhouse gas emissions in the rumen of paper mulberry silage by shifting bacterial community composition.

“…After the rst extraction of traditional Chinese medicine, about 30% of its active components remain in the residue due to the low utilization e ciency of traditional Chinese medicine, including bioactive substances such as alkaloids, terpenoids, avonoids and quinones remain (Huang et al 2021). Stacking, incineration and land ll are the main treatment methods of TCMR in traditional Chinese medicine production enterprises in China (Wang et al 2021;Zhan et al 2017), not only causing serious harm to the ecological environment, but also leading to a great waste of resources. Therefore, it is of signi cant to develop an environmentally friendly treatment method for TCMR, consequently solving the problem of environmental pollution and realizing the e cient utilization of resources.…”

PurposeThe study aims to search for efficient cellulase producer and explore the possibility of traditional Chinese medicine residue as a substrate for cellulase production, so as to realize the waste utilization of traditional Chinese medicine residue.MethodsThe cellulase-producing strain was identified through morphological and molecular biological methods. Scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to characterize the structure of traditional Chinese medicine residues before and after fermentation. The enzyme activity was determined by DNS method, and the enzyme production conditions were optimized by single factor and response surface methodology.ResultThe strain grew well in forsythia leaf residue, and the highest FPA could reach 2.06 IU/mL. In addition, the structural characteristics of traditional Chinese medicine residue that before and after enzymatic hydrolysis were characterized by SEM and FTIR. The results showed that the structure of the residue was destroyed after enzymatic hydrolysis, the damage of forsythia leaf residue was the most serious, and enzymatic hydrolysis promoted the dissolution of cellulose, lignin and hemicellulose. The enzyme production conditions of the strain were optimized by Plackett-Burman design and response surface analysis. The FPA could reach 2.79 IU/mL under the optimal conditions of FLR concentration 24.84 g/L, (NH4)2SO4 concentration 2 g/L, temperature 34.44℃, pH 6.20, rotational speed 200rpm, inoculum 6%, which was 35.44% higher than that before optimization.ConclusionsThe results showed that traditional Chinese medicine residue could be used as the induced substrate for fungal cellulase production. This study provides an idea for the low-cost production of fungal cellulase and the waste utilization of traditional Chinese medicine residue.
