With our unique ion technology, we instantly transform oil stains into "organic matter." This technology, based on electrons rather than molecules, utilizes enzyme power for ion cleaning, breaking down the molecular structure of oils and dirt in an instant. There is no reattachment of oil, making cleaning easier. The moment the cleaning agent comes into contact with grease, the transformation begins, eliminating stickiness and slipperiness, allowing for easy removal of oil stains and reducing cleaning time. Even stubborn dirt on range hoods can be easily removed, and the sponges used for cleaning do not allow for reattachment, making the cleaning process simpler. An environmentally friendly next-generation cleaning agent, the oil transformed into "organic matter" is biodegradable by microorganisms, making it an eco-friendly cleaner. The more you use Calfa L-740, the more it transforms the oil adhered to grease traps, building pits, and pipes into organic matter, gradually cleaning them. Calfa L-740 is a multifunctional cleaning agent that can be used not only for cleaning kitchens but also for surrounding kitchen equipment, dishwashers, toilets, bathtubs, glass, chairs, tables, and more. When used in conjunction with "Dr. GreastEX," it effectively cleans heavily soiled areas such as floors, grates, and the insides of pipes.

Recycled waste tires were transformed into chips and reborn as bollards. Compared to traditional stone products, they are elastic and help cushion impacts when struck. As a result of installing Jizo-shaped bollards in areas with frequent illegal dumping, there have been reports of a decrease in illegal dumping.
