We will exhibit plant-based deodorants at the "Food Processing Technology Exhibition 2025."

I am skilled at on-site responses on the same day. I can eliminate odors without changing existing equipment. I can address complaints about unpleasant odors from nearby residents and improve the working environment within the factory.

A factory with "minimal odor" can also enhance the company's image. ■Specific Concerns - Changes to the manufacturing process are necessary due to complaints of foul odors from residents. - Unable to change raw materials or manufacturing processes but want to eliminate odors. - New employees are leaving due to odor issues. - Want to eliminate odors during customer factory tours. - Odors only occur during the production of a specific product, so do not want to invest in deodorizing equipment. - Concentration of substances is not an issue; just want to eliminate the odor. There are various concerns regarding odors. ■Solutions with Sanyu's Deodorization Technology - No need to change existing equipment. - Can be used in a space-saving and cost-effective manner. - No waste is generated. - Odor specialists will respond on-site. - You can confirm deodorization effects through on-site testing and calculate costs on the spot. ⇒ We will propose solutions centered around "plant-derived deodorants" that consider the environment. ■Customer Feedback Upon Implementation - Realized that it is not necessary to eliminate all odors to stop complaints. - Did not expect that a simple deodorant could solve the problem instead of a large-scale deodorization system. - It was helpful to implement at a low cost. The ability to stop using it if not needed is also a benefit.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture.
