Growth of Rubber Seeds (Hevea brasiliensis Muell.Arg) from Sleeping Eye Stum by Applying Organic Fertilizer Bulk and Liquid Herbal Waste

The organic fertilizer derived from herbal medicine waste in both bulk and liquid form is rich in macro and micro nutrients as well as decomposing microbes and probiotic bacteria needed to improve soil chemical properties. These fertilisers can be used to obtain better growth of rubber seedlings, especially rubber seedlings of sleeping eye origin. The objectives of this study was(1) to determine the effect of organic fertilizer and liquid bulk herbs Against Waste growth and (2) to know nutrient uptake of N, P, and K seedling stum Sleep eye. The study was conducted in a 4 x 3 factorial experiment arranged in a completely randomized design (CRD) with five replications. The first factor is the concentration of organic liquid fertilizer consisting of four in the standard: h0 = 0 ml L-1 of air (0%); h1 = 2 ml L-1 air (0.2%); h2 = 4ml L-1 air (0.4%); h3 = 6ml L-1 air (0.6%). The second factor is the dose of organic fertilizer consists of three levels: (b0 = 0 mg ha-1: b1 = 5 mg ha-1: b2 = 10 Mg ha-1). Data were analyzed with Analysis of Variant and continued with Duncan's Multiple Range Test 5% level. The results showed that the dosage of bulk organic fertilizers was significantly different at the level of 5% of the uptake of nitrogen, other observations were not significantly different. While the treatment of liquid organic fertilizer was highly significantly different at the level of 1% of nitrogen absorption, other observations were not significantly different. No real effect on their interaction in all observations. The treatment dose of organic fertilizer 5 Mg ha-1 and the treatment of liquid organic fertilizer 4 ml L-1 provided the highest results in leaf area of 586.46 cm2 per plant compared to the control treatment of 181.06 cm2 per plant. The treatment of bulk organic fertilizer dose and liquid organic fertilizer concentration predicted P2O5 nutrient uptake per rubber plant did not show significant differences. While the treatment of doses of bulk organic fertilizer and concentrations of liquid organic fertilizer is thought to be potassium nutrient uptake per rubber plant does not show significant differences, but can be seen from the growth of diameter, number of leaves, and leaf area.

An innovative way to treat cash crop wastes: The fermentation characteristics and functional microbial community using different substrates to produce Agricultural Jiaosu

With the increase of global demand for cash crops, a large of cash crop waste was produced and caused severe environmental issues. To produce Agricultural Jiaosu (AJ) using these wastes is a sustainable waste disposal method. However, the fermentation mechanism, metabolites, and microbial characteristics of AJ fermented with different substrates remain unclear. In this study, the effects of different substrates (fruit and vegetable waste and Chinese herbal medicine waste) on the fermentation characteristics of AJ, including metabolites and microbial community properties, were investigated. The results revealed that AJ fermentation was a process of converting organic matter into organic acids and other metabolites, mainly including hydrolysis, acidogenesis, and maturation stages. At the genus level, Lactobacillus, Acetobacter, Hydrogenibacillus, Halomonas, and Prevotella_1 were the dominant bacteria in the fermentation system. The bacterial diversity of composite substrate AJ was higher than that of single substrate AJ. The organic acids and secondary metabolites concentration and the composition of key microorganisms depended on the substrate type. Furthermore, AJ's potential functional genes were mainly concentrated in cofactors and vitamin, carbohydrate, and amino acid metabolism. The findings of this study indicated that AJ is an innovative eco-friendly technology that can convert cash crop wastes into sustainable eco-products, and that its characteristics depend on the substrate type. Therefore, the substrate used to produce AJ should be carefully selected according to the application field.

Reed Rhizome Residue-Based Activated Carbon Adsorption Ultrafiltration Membranes for Enhanced MB Removal.

Novel adsorption ultrafiltration (ADUF) membrane was designed for the removal of methylene blue (MB) by introducing Chinese herbal waste-based activated carbon (AC) into the ultrafiltration membrane. We prepared AC particles from Chinese herbal medicine waste residue (reed rhizome residue) as a raw material by ZnCl2 activation and introduced them into the ultrafiltration membrane by phase inversion to prepare a reed rhizome residue-based activated carbon adsorption ultrafiltration (RAC-ADUF) membrane. The RAC-ADUF-0.1 membrane was characterized by a series of physical structures and chemical properties, which showed that the prepared membrane has a more hydrophilic surface and high porosity. The RAC-ADUF-0.1 membrane showed an excellent pure water flux of 255.77 L·m-2·h-1 and a high bovine serum albumin rejection of 99.3%. The RAC-ADUF membranes also possessed excellent antifouling performance. Notably, the RAC-ADUF-0.1 membrane provides excellent removal of MB (99% retention) compared to conventional ultrafiltration membranes. The static adsorption capacity was up to 238.48 mg/g. The significant increase in dynamic adsorption capacity on the RAC-ADUF membrane is due to the three-dimensional distribution of RAC particles on the PSF membrane cross section, which provides more active sites and increases the contact time between RAC and MB. By fitting the adsorption kinetics and isothermal adsorption curves, the results showed that the pseudo-second-order kinetic model and the Langmuir isothermal model were more accurate in explaining the adsorption process. Further kinetic analysis showed that the adsorption process of MB molecules on RAC-ADUF membranes is controlled by both external mass transfer and intraparticle diffusion, with intraparticle diffusion playing a dominant role. In addition, the RAC-ADUF membrane exhibited outstanding adsorption and regeneration abilities, and the MB removal rate stayed at about 95% after 8 adsorption regeneration experiments. In conclusion, this study provides a new idea for the preparation strategy of an adsorption ultrafiltration membrane with high rejection and high permeability and the reuse of Chinese herbal medicine waste residue.

Catalytic fast pyrolysis of herbal medicine wastes over zeolite catalyst for aromatic hydrocarbons production

Catalytic pyrolysis is an effective method to upgrade biomass pyrolytic bio-oil. In this study, catalytic fast pyrolysis (CFP) of licorice residue (LR) over ZSM-5 was conducted using pyrolysis–gas chromatography/mass spectrometry. The effects of temperature, Si/Al atomic ratio (SAR) and catalyst to feedstock (C/F) ratio on the formation of aromatic hydrocarbons (AHs) were investigated. The results indicated that ZSM-5 effectively converts oxygenates into AHs. Specifically, benzene, toluene, ethylbenzene, p-xylene and naphthalene (BTEXN) were the dominant components. The pyrolysis temperature and acidity of zeolite exert a greater influence on the formation of BTEXN. The maximum content of BTEXN was 73.45 % at 500 °C and 72.21 % at lower SARs (27 and 36). Coke can be formed and deposited on the zeolite during CFP of LR, which cause the deactivation of catalyst. A higher pyrolysis temperature and C/F ratios inhibits the coke formation, while a higher SAR is beneficial to coke formation. The large oxygenated molecules and aliphatic hydrocarbons (AHCs) was the precursors of coke during catalytic pyrolysis. The coke was tended to disperse on the surface of catalyst at low temperature. However, it was largely deposited in the channels of zeolite catalyst at high temperatures. This study reveals that ZSM-5 is an effective catalyst for the utilization of herbal medicine wastes. The pyrolytic bio-oil has high potential for use in fuels or renewable chemical production.

Green products from herbal medicine wastes by subcritical water treatment

Herbal medicine wastes (HMWs) are byproducts of medicine factories, which are mainly landfilled for their environmental problems. Only bearing in mind the contamination and concerns caused by the COVID-19 pandemic and environmental emissions, the worth of herbal medicine wastes management and conversion to green products can be understood. In this work, subcritical water treatment was carried out batch-wise in a stainless tube reactor in the pressure range of 0.792–30.0 MPa, varying the temperature (127–327 °C) and time (1–60 min) of extraction. This resulted in new and green material sources, including organic acids, amino acids, and sugars. Amazingly, at very low extraction times (below 5 min) and high temperatures (above 277 °C), about 99% of HMWs were efficaciously converted to clean products by subcritical hydrothermal treatment. The results of hydrothermal extraction after 5 min indicated that at low temperatures (127–227 °C), the total organic carbon in the aqueous phase increased as the residual solid phase decreased, reaching a peak around 220 °C. Acetone soluble extracts or fat phase appeared above 227 °C and reached a maximum yield of 21% at 357 °C. Aspartic acid, threonine, and glycine were the primary amino acids; glycolic acid, formic acid, lactic acid, and acetic acid were obtained as the main organic acids, glucose, fructose, and cellobiose were substantial sugars produced from the aqueous phase after 5 min of hydrothermal subcritical hydrolysis extraction.

Pyrolysis of torrefied herbal medicine wastes: Characterization of pyrolytic products

Torrefaction is beneficial for improving the pyrolysis product quality. To study the feasibility of utilizing herbal medicine wastes (HMWs), pyrolysis of torrefied HMWs was performed. The effects of torrefaction on the properties of products and the evolution law were examined. The results show that the torrefaction temperature exerts a greater influence on the yield and quality of products from HMWs pyrolysis than that of the torrefaction atmosphere. CO was the predominant component in the gas, and its yield increased with both the torrefaction and pyrolysis temperatures. H2 and CH4 started to be released at ≥600 °C due to dehydrogenation and condensation reactions. Acids, ketones and anhydro-saccharides (AS) were the major compounds in bio-oil from 400 to 600 °C, while phenols, aromatics and N-containing compounds dominated at high temperatures. Torrefaction at high temperatures and under oxygenated atmospheres facilitated the formation of larger aromatic ring structures. Pyrolysis of torrefied HMWs under CO2 and O2 and 260 °C produced more CO, CO2 and acids but fewer phenols than that under N2. The obtained results are beneficial for the development of an effective utilization method for HMWs.

Catalytic Pyrolysis as a Technology to Dispose of Herbal Medicine Waste

The use of herbal medicine has increased tremendously over the last decades, generating a considerable amount of herbal medicine waste. Pyrolysis is a promising option to dispose of biomass and organic waste such as herbal medicine waste. Herein, an activated carbon-supported Pt catalyst (Pt/AC) and carbon dioxide (CO2) were applied to the pyrolysis of real herbal medicine waste to develop a thermal disposal method to prevent the formation of benzene derivatives that are harmful to the environment and human health. When using the Pt/AC catalyst in the pyrolysis of the herbal medicine waste at 500 °C, the generation of benzyl species was suppressed. This was likely because the Pt catalytic sites accelerate a free radical mechanism that is dominant in the thermal cracking of carbonaceous substances. However, the employment of CO2 (instead of typically used N2) as a pyrolysis medium for the herbal medicine waste pyrolysis did not decrease the concentrations of benzyl compounds contained in the pyrolytic products of the herbal medicine waste. This study might help develop a method to thermally dispose of agricultural biowaste, preventing the formation of harmful chemicals to the environment and human beings.

Preparation of activated carbons from a kind of Chinese herbal medicine wastes by phosphoric acid and CO2 activation

The effects of parameters on the adsorption capacity of activated carbons (AC) prepared from Chinese Herbal Medicines Wastes (CHMWs) by phosphoric acid and CO2 activation were studied. Response surface methodology (RSM) was used to optimize the process parameters for preparing activated carbon from CHMWs. The results showed that the optimal conditions were as follows: impregnation ratio of 2.61, activation temperature of 700 °C, activation time of 2.5 h and the CO2 flow rate was 50mL/min. The adsorption value of iodine and methylene blue of the resultant activated carbon was 626.83 mg/g, 278.99 mg/g, respectively. The Activated Carbon prepared from Chinese Herbal Medicines Wastes (CHMWs) shows high adsorption capacity and well-developed pore structure.

Torrefaction of herbal medicine wastes: Characterization of the physicochemical properties and combustion behaviors

To explore the feasibility of using herbal medicine waste (HMW) as solid fuel, HMW was torrefied under different temperatures and atmospheres. The physicochemical properties and combustion behaviors of the torrefied HMW were investigated. Temperature was found to be the most influential factor affecting the torrefaction. Torrefaction improved the hydrophobicity of HMW and decreased the equilibrated moisture uptake from 24.48(0.083) % to 15.22(0.054) %. The HMW samples torrefied under different conditions are easy to ignite. The comprehensive combustibility index (S) of the torrefied HMW increased by 3–5 folds compared to that of the raw sample. In general, the HMW torrefied under lower temperatures and under CO2 and O2 have better flammability. The present results revealed that the torrefied HMW exhibited good combustion characteristics and can thus be used for solid fuel production, such as fuels for co-combustion or raw materials for pelletization.

The potential of Bacillus strains isolated from the rumen content of dairy cows as natural antibacterial and antioxidant agents for broilers

The study was conducted to investigate the in vitro antibacterial activity and antioxidant-enhancing effect of Bacillus strains isolated from the rumen content of dairy cows. The antibacterial activity of Bacillus strains was assessed against Escherichia colibased on the agar-well diffusion method. To assess the antioxidant-enhancing effect, the Bacillusstrains was mixed (prepared as multi-strains) and used to ferment herbal medicine waste (HMW). The effect was compared with that of commercial probiotic Bacillus subtilis and non fermented HWM. Results showed that each Bacillus strain was able to inhibit the growth of E. coli. Fermentation with mixed Bacillus strains tended (P=0.07) to enhance the 2,2-diphenylpicrylhydrazyl (DPPH) radicals scavenging activity and total phenolics content of HMW. In contrast, fermentation with commercial Bacillus subtilis tended (P=0.07) to decrease DPPH radical scavenging activity and total phenol of HMW. Fermentation with both Bacillus preparations increased (P<0.05) the contents of crude protein and ash in HMW, while crude fat increased (P<0.05) in HMW fermented with Bacillus subtilis. Fermentation either with Bacillus subtilis or mixed Bacillus strains increased (P<0.05) the fiber content of HMW. In conclusion, Bacillus strains isolated from the rumen content of dairy cows showed antibacterial activity and antioxidant-enhancing effect, therefore, they are potential as feed additive to substitute synthetic antibiotics and antioxidants for broilers raised under tropical conditions.

Low-cost magnetic herbal biochar: characterization and application for antibiotic removal.

Magnetic biochar (M-BC) was derived from herbal medicine waste, Astragalus membranaceus residue, and was used as an adsorbent for ciprofloxacin removal from aqueous solutions. The M-BC was characterized by Brunauer-Emmett-Teller surface area analyses, Fourier transform infrared spectrometry, X-ray diffraction analysis, hysteresis loops, scanning electron microscopy energy-dispersive spectrometry, and X-ray photoelectron spectroscopy. The BET surface area increased from 4.40 to 203.70m2/g after pyrolysis/magnetic modification. Batch experiments were performed at different dosages, initial concentrations, contact times, and solution pHs. Adsorption performances were evaluated using Langmuir and Freundlich isotherm models, and the results indicated that the Langmuir model appropriately described the adsorption process. The kinetic data were better fitted by a pseudo-second-order kinetic model. The maximum ciprofloxacin removal was observed at pH 6 (adsorption capacity of 68.9±3.23mg/g). Studies demonstrated that magnetically modified biochar might be an attractive, cost-effective, and easily separated adsorbent for contaminated water. Graphical abstract.

Low-cost biochar derived from herbal residue: characterization and application for ciprofloxacin adsorption

Thermally carbonization biochar produced from a traditional Chinese herbal medicine waste (Astragalus mongholicus residue) was investigated for its performance in ciprofloxacin adsorption. Batch sorption experiments were conducted, and scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and Brunauer–Emmett–Teller surface area analyses were employed to characterize the biochar. The results demonstrated that thermal activation process improves the adsorbent characteristics. Biochar produced at 800 °C had the best adsorption capacity, a better pore structure and the largest surface areas. The adsorption process fit well to a pseudo-second-order kinetics model. The adsorption isothermal model results revealed that the adsorption process of ciprofloxacin is described better by the Freundlich isotherm and the type of adsorption is a chemical process. The maximum adsorption of ciprofloxacin occurred at pH 7. The present research demonstrated that A. mongholicus biochar might be an attractive and cost-effective adsorbent with good adsorption performance for removing ciprofloxacin from water solution.

Biosorption of methylene blue from wastewater by an extraction residue of Salvia miltiorrhiza Bge

Efforts were made in this study to using an extraction residue of Salvia mitiorrziza Bge (SM), a widely utilized traditional Chinese medicine, as an effective biosorbent of methylene blue from polluted water. Batch experiments were carried out with original and chemical modification, particle size, dosage, solution pH, contact time, and initial concentration of the dye. Experimental data fit Langmuir isotherm and pseudo-second order kinetic best compared to other models applied in the study. Characterization of adsorption was determined by FT-IR, SEM and particle surface area measurement. The maximum monolayer biosorption capacity of raw SM is 100.0mg·g−1. The citric acid and Na2CO3 modification can significantly enhance this value up to 161.29 and 178.57mg·g−1, respectively. This investigation provides a novel approach for reutilizing the enormous quantity of Chinese herbal medicine wastes, which is significant since these dregs have brought out big environmental and heathy problems in the present China.

Activated Carbon from the Chinese Herbal Medicine Waste by H3PO4 Activation

Large amounts of Chinese herbal medicine wastes produced by the medicinal factories have been mainly landfilled as waste. In this study, via phosphoric acid activation, a Chinese herbal medicine waste from Magnolia officinalis (CHMW‐MO) was prepared for activated carbon (CHMW‐MO‐AC). The effect of preparation conditions (phosphoric acid/CHMW‐MO impregnation ratio, activation temperature, and time) of activated carbon on yield of CHMW‐MO‐AC was investigated. The surface area and porous texture of the CHMW‐MO‐ACs were characterized by nitrogen adsorption at 77 K. The SBET and pore volume were achieved in their highest value of 920 m2/g and 0.703 cm3/g, respectively. Thermal gravity analysis and scanning electron microscope images showed that CHMW‐MO‐ACs have a high thermal resistance and pore development. The results indicated that CHMW‐MO is a good precursor material for preparing activated carbon, and CHMW‐MO‐AC with well‐developed mesopore volume can be prepared by H3PO4 activation.

Studies on the development of functional paper with herbal medicine and herbal medicine waste(Part 1) -Development of functional paper with Astragalus membranaceus, Angelica acutiloba and Artemisia capillaris waste-

This research was performed to make functional papers by using the waste of herbal medicine such as Astragalus membranaceus, Angelica acutiloba, and Artemisia capillaris as additives, and to evaluate their physical and optical properties of the manufactured paper. The physical and optical properties were decreased with the increase of the amount of herbal medicine. Of those manufactured papers, the functional paper with Artemisia capillaris showed the dramatic decrease in its physical properties. Adding the herbal medicine waste as additives developed the aesthetic pattern on the surface of the manufactured paper. The paper showing the black pattern on white surface was most favored. Different patterns could be made by changing the size of fibers and the amount of wastes. There was odor emitted from the paper due to the herbal medicine waste, which make the paper to have a potential for the diverse purpose. The herbal medicine waste can be applied to replace weighting agents in the manufacturing process of paper or used for the fuctional additives, resulting in the reduce of the quantity of a pulp consumed. The paper with 10-20% Angelica acutiloba waste were thought to have the most excellent quality on the process point of view.

Study on pyrolysis characteristics of medical waste

China is the largest producer of traditional Chinese herbal medicine in the world. Chinese herbal medicine waste (CHHMW) is a byproduct of Chinese medicine factory and treated directly by landfill. In this way, untreated traditional CHHMW will cause more and more environmental problems. Therefore, it is urgent to reuse and hazard freely treat CHHMW. The CHHMW treated by thermochemical process is a better way than landfill. For this aim, in this paper, pyrolysis characteristics and kinetics of three CHHMWs were investigated by thermogravimetric analysis. The experiment results show, under the experimental condition, that heating rate and particle size have little impact on the pyrolysis process and the judgment of pyrolysis mechanism. The pyrolysis kinetic parameters of three CHHMWs under different heating rates were calculated using the modified Freeman–Carroll method.

Study on Fluidization Characteristics of Chinese Herbal Medicine Waste in a Fluidized Bed Reactor

Large amounts of Chinese herbal medicine wastes (CHMW) are produced in the process of processing and manufacturing traditional Chinese crude medicines. For CHMW, gasification in fluidized bed is a promising option. But, it is the difficult to fluidize CHMW particles alone in fluidized bed gasifier, especially for various size and shape of CHMW particles. It is very common to fluidize these kinds of biomass particles with sand, gives better defined fluidization behavior and a more reliable scale-up. However, not much is known about fluidization behavior of CHMW particles in fluidized bed. Therefore, a fluidized bed and its air distribution were designed and set up, the experimental study on fluidization characteristic of CHMW was done in the fluidize bed. Minimum fluidization velocity and the effect of bed height of CHMW/quartz sand mixtures on fluidization properties in air have been experimentally determined. The results showed that good fluidized could achieve with the additional of quartz sand. The results will be in favorite design and operation of CHMW gasification in fluidized bed.
