To reduce the production cost of $Pleurotus$ $ostreatus$, discarded medicinal sludge was collected from oriental medical clinics to develop the $Pleurotus$ $ostreatus$ culture medium. According to the analysis of the proximate composition of the materials used in Korean herb medicine, the crude ash contents of $Carthamus$ $tinctrius$ L stem and $Acanthopanax$ $chiisanensis$ were 11.6% and 10.1% respectively, which were relatively higher than the 9.6% of the control medium, waste cotton. Crude protein was detected in 9.8% of the waste cotton medium, whereas it was detected in 14.9%, 13.9%, 13.4%, and 11.5%, of wild mugwort, $Acanthopanax$ $\underline{chiisanensis}$, medicinal sludge, and $Carthamus$ $tinctrius$ L stem, respectively, which are all higher than the control. The pH of medicinal sludges, wild mugwort, and $Aacanthopanax$ $chiisanenses$ ranged from 5.27 to 5.72, which was similar to the 5.70 pH value of waste cotton. In the case of addition concentration of each Korean herb medicine material influencing mycelial growth of the $Pleurotus$ $ostreatus$, the 9% concentration was more favorable compared to that of 3% and 6%. However, the addition of Korean herb medicine materials did not significantly affect the growth of $P.$ $tolaassi$ and $Trichoderma$ $sp.$ According to a field experiment that added 9% of medicinal sludge into the waste cotton medium, the mycelial growth of mushrooms was facilitated by approximately 2 days, and the mushroom yield was increased by 10~15%. Furthermore, pileus and stipe of the mushrooms were even and superior in quality.

In order to reuse remnants of medicinal herb extracts as an environment-friendly manure, fermented compost made from medicinal herb waste (MHWC), poultry manure compost (PMC) and MHWC+PMC (1:1, w/w) were applied on upland soil cultivated with 2 year-old Bokbunja plants. The results of the changes of soil chemical properties on upland soil, the yield and the sugar contents of the fruit harvested were summarized as follows. The pH in soils treated with composts (STCs) was significantly changed (p<0.05) compared with untreated control (UC) group. The electrical conductivity (EC) in MHWC group was decreased 0.46-0.56 times compared with UC, and it was different from PMC groups. The contents of organic matter and total nitrogen were increased in all of the treatments and MHWC group was the highest among the all groups. The content of available phosphorous was different by types and amounts of the composts. The content of heavy metal in all groups did not exceed the standard content for soil contamination. The yield and the sugar contents of the fruit harvested were the highest in the treatments of MHWC. In conclusion, MHWC is an effective compost resource on improvement of soil environment and promoting the fruit qualities.

Fermented compost made from medicinal herb waste (MHWC) as an environment-friendly manure was applied to determine the physicochemical characteristics of Rubus coreanus Miquel (Bokbunja). MHWC, poultry manure compost (PMC), and MHWC+PMC (1:1, w/w) were applied to 2 year-old Bokbunja plants at levels of 0 (UC: untreated control), 20, and 40 Mg/ha, respectively. The physicochemical characteristics of Bokbunja were investigated 15, 20, and 25 days after flowering (DAF). There were no differences between the chemical compositions of the group. However, the total sugar contents of the fruit harvested 15, 20, and 25 DAF from MHWC were increased 0.54~0.56, 0.46~0.53, and 1.80~2.52%, respectively, as compared with UC. The free sugar content in fruit from the MHWC group was higher compared to the other groups. The fructose and glucose contents were increased 0.08~0.31% and 0.08~0.18%, respectively. The organic acid content of the fruit was increased in the MHWC and PMC groups, and citric acid constituted 92.67~93.59% of the total organic acid content. In conclusion, MHWC treatment is a compost source for quality improvement of total sugar, free sugar, and organic acid contents of Bokbunja.

Fermented compost made from medicinal herb wastes (MHWC) as an environment-friendly manure resource was applied to determine physiological activities of Rubus coreanus Miquel (Bokbunja). MHWC, poultry manure compost (PMC), and MHWC+PMC (1:1, w/w) were applied to 2 year-old Bokbunja plant at levels of 0, 20, 40 Mg/ha, respectively. Physiological activities of Bokbunja were investigated at 15, 20 and 25 days after flowering (DAF). Content of total phenolics in fruit was high in order of 25 > 20 > 15 DAF, showing highest value in fruit treated with MHWC at 40 Mg/ha. The flavonoid level showed same pattern to total phenolics. Electron donation abilities at fruits at 15 and 20 DAF were higher than at 25 DAF. Nitrite scavenging ability (NSA) was increased on in order of pH 1.2 > 4.2 > 6.0. NSA in fruit at 15 and 20 DAF was higher than at 25 DAF. Tyrosinase inhibition ability at fruits treated with MHWC showed the highest value among all composts. Xanthine oxidase inhibition ability in fruit treated with MHWC at 25 DAF was the highest. In conclusion, physiological activities of Rubus coreanus Miquel (Bokbunja) were improved in MHWC group.

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.

The lees of Korean traditional wine called as Jubak or Sul-jigemi in Korea is byproduct from alcohol fermentation industry, which is remnant of fermentation broth after filtration, centrifugation, distillation, or sedimentation during aging. Since, Korean traditional wines are produced from edible plant sources such as rice, foxtail millet, fruits and medicinal herbs with nuruk (a traditional fermentation starter and starch degrader), the Jubak from rice wine (takju), medicinal herb wine (yakju) and fruits wine are considered as safe byproduct and have various useful bioactivity. Considering the recent rapid increased production of Jubak from takju industry, and the reinforcement of dispose of Jubak as waste material in worldwide, the development of efficient reuse process for Jubak is necessary in traditional wine industry. In this review, the status of current industry, research and patent trends in relation with Jubak production, treatment, utilization and renewal was analyzed and different bioactive compounds including phenolic acids from Jubak were provided. Jubak is not any more waste material, and is the source of bioactive functional materials for food, cosmetics and medicinal industry. To develop the efficient and economic renewal technology including recovery process for bioactive substances from Jubak, systematic collaboration and research among the industry, academy and government is necessary.
