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.

Nishigo Village in Fukushima Prefecture is focusing on food education for children through local production for local consumption activities and participation in the "Delicious School Lunch Contest." To effectively utilize the leftovers from the approximately 2,000 school lunches prepared daily, they have introduced Bio Clean at the Fukushima Prefecture Nishigo Village School Lunch Center. Additionally, at the Hitachi City Southern School Lunch Joint Cooking Facility, they are composting the cooking leftovers and food waste from 9,800 students in local elementary and junior high schools. After a three-year demonstration project, the system was officially implemented, and currently, two 500 kg processing units are in operation. 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. For more details, please contact us.

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.

The "Bio Clean BC-10 model" is a commercial food waste processor developed in collaboration with Tohoku University, utilizing the "acidic compost decomposition method." More than 85% of the food waste input is decomposed and eliminated by microorganisms, while the remaining portion can be used as high-quality compost for growing organic vegetables and other plants. It also excels in the sustainability of its decomposition power, allowing for operations with reduced running costs. Currently, in addition to offering compost samples as a gift, we are providing free rental of small units (shipping costs separate). If you are interested, please contact us via the [Contact Form]. [Features] ■ Significantly reduces costs associated with the addition and replacement of decomposing bacteria (substrate) ■ Processing capacity of up to 10 kg per day (equivalent to approximately 100 servings of food waste) ■ Minimal ammonia volatilization, suppressing odor generation ■ A lineup of series products that can be selected according to processing volume *You can view the catalog of the "Bio Clean Series," which includes features and delivery records, from the [Download] section.

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.

The food waste processor is not a product that exists in abundance in the world, nor is it a product that everyone knows about. Therefore, there are many aspects that cannot be understood from catalogs or specifications. What everyone is particularly concerned about are "odor," "decomposition state," and "noise," right? For that reason, we try to show you the actual sites where it is being used as much as possible. If possible, our staff will accompany you to provide explanations. For those considering the introduction of a food waste processor, please feel free to contact us if you would like to check the "odor," "decomposition state," and "noise" of BioClean.

Our bio toilet has been adopted by a mountain lodge. Previously, they had a chair in the toilet room where a plastic bag could be set, operating on a "take your own waste back" system. However, they faced difficulties with people leaving their waste behind or discarding it along the hiking trails. To address this, they installed solar panels on the roof of the lodge and introduced our bio toilet "Violet BT-L" (which can be used up to 40 times a day). At first, users were unsure how to use it, but they successfully navigated the hiking season from June to October and have reported that they completed this season's operations without any issues.
