The Asidoro® composting method, developed in collaboration with Tohoku University Graduate School of Engineering, decomposes kitchen waste stably over a long period. Therefore, the addition or replacement of decomposing microorganisms is unnecessary for an extended time. About 85% of the kitchen waste introduced into the BioClean is decomposed and disappears. The remaining approximately 15% can be used as high-quality organic compost. Research on the fertilizer effects, such as vibrant flower colors, vigorous vegetable growth, and sweeter fruits, has been conducted for many years at the Tohoku University Faculty of Agriculture. The Asidoro® composting method is characterized by its acidic progression. As a result, the volatilization of ammonia and other odor-causing substances is suppressed, reducing odors. Additionally, by suppressing ammonia volatilization, the generation of nitrous oxide, which is considered particularly potent among greenhouse gases, is also minimized. For more details, please contact us.

In companies, organic waste generated from employee cafeterias is processed. There is an active effort to handle waste generated within the company on-site, reducing the amount of waste produced by the company. At JGC Corporation, a commercial organic waste processor called BioClean has been introduced at the company's construction camp on Sulawesi Island, Indonesia, to hygienically process organic waste generated from the kitchen. This special model is designed to accommodate the local power supply situation, supporting a 400V 50Hz three-phase supply from a generator, and has replaced the automatic input lifter with a step for input equipped with safety barriers.

Research institutes, testing grounds, and local governments utilize it for processing plants cultivated in experiments and for handling organic waste generated at fishery testing grounds. At the Kagawa Prefectural Agricultural Experiment Station, BioClean was introduced as part of a recycling experiment to compost vegetable scraps from crops grown at the test farm and return them to agricultural land. Due to the need to continuously decompose large amounts of vegetable scraps, the high decomposition power and sustainability of the Acidro® composting method were key factors in the selection process.

• IC tag

Inlay is the most basic form of an IC tag, where an IC chip is connected to an antenna. It features a wire-wound antenna made of copper, which allows for a wide range of size and shape options. Additionally, by fine-tuning the antenna size, it is also possible to adjust the resonant frequency. Even when there are pre-defined constraints on size and shape, such as when used in a resin-molded case, we propose inlays that maximize their characteristics within those constraints.

The "Bio Clean" series of bio-style kitchen waste processors adopts the Acidro compost decomposition method, allowing for the rapid decomposition of organic waste such as kitchen scraps with minimal residue. It features three characteristics that solve the issues faced by conventional kitchen waste processors, such as the costs and effort involved in replacing decomposition substrates and deodorants, as well as odor problems. The exhaust is discharged through a deodorizing device, which effectively cuts odors using a complex microbial deodorization method. Additionally, the compost extracted from the Bio Clean contains a high amount of nitrogen, phosphorus, and potassium (especially nitrogen), which are essential for plant growth, and it also provides a well-balanced supply of trace minerals, making it a high-quality fertilizer. We offer a wide range of processing capacities from 2 kg/day to 500 kg/day, tailored to various applications. For more details, please download the catalog or contact us.
