“…The experimental results showed that when the sample weight was constant, the higher heating rate would move the peak deformation and characteristic peak temperature to higher values. 33 (Fig. 1A) Finally, 8 1C min À1 was selected as the heating rate by comparing the DSC curves at different heating rates.…”

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.

“…The annual output of Chinese medicine industry waste (CMIW), a type of organic solid waste containing many bacteria, is huge [1]. It can reach six to seven million tons per year [2][3][4]. The unreasonable disposal of CMIW causes environmental pollution and ecological damage and threatens human health [5].…”

Alkali Etching Hydrochar-Based Adsorbent Preparation Using Chinese Medicine Industry Waste and Its Application in Efficient Removal of Multiple Pollutants

The annual discharge (6–7 million tons per year) of Chinese medicine industry waste (CMIW) is large and harmful. CMIW with a high moisture content can be effectively treated by hydrothermal carbonization (HTC) technology. Compared with CMIW, the volume and number of pores of the prepared hydrochar increased significantly after alkali etching (AE), and they had abundant oxygen-containing functional groups. These properties provide physical and chemical adsorption sites, improving the adsorbent activity of the alkaline etching of Chinese medicine industry waste hydrochar (AE-CMIW hydrochar). However, few studies have investigated the adsorption of organic dyes and heavy metals in mixed solutions. This study proposed a method of coupling HTC with AE to treat CMIW and explored the potential of AE-CMIW hydrochar to remove metal ions and organic dyes from mixed solution. We analyzed the removal rates of metal ions and organic dyes by the adsorbents and investigated their differences. The results showed that the lead ion, cadmium ion, and methylene blue could be efficiently removed by AE-CMIW hydrochar in a mixed solution, with removal rates of more than 98%, 20–57%, and 60–80%, respectively. The removal rates were different mainly due to the various electrostatic interactions, physical adsorption, differences in the hydrating ion radius of the metal ions, and functional group interactions between the AE-CMIW hydrochar and the lead ion, cadmium ion, and methylene blue. This study provides a technical method for preparing multi-pollutant adsorbents from CMIW, which enables efficient utilization of organic solid waste and achieves the purpose of treating waste with waste.
