Announcement of the Launch of Petri Dish Recycling Initiative— Collaboration with atect Corporation Toward Achieving the SDGs (Sustainable Development Goals) —

2025.06.05

HIROTSU BIO SCIENCE Inc. (hereinafter “HIROTSU”) has commenced a recycling initiative for used Petri dishes utilized in research and testing, in collaboration with atect Corporation (Head office: Higashiomi City, Shiga Prefecture, Japan; Representative Director: Makoto Onishi; hereinafter “atect Corp.”), one of Japan’s leading manufacturers and suppliers of Petri dishes. As a company dedicated to contributing proactively to the realization of a sustainable society, HIROTSU is partnering with atect Corp., the nation’s only sanitary testing equipment manufacturer that produces both Petri dishes and culture media.

This initiative aims to reduce environmental impact and promote a resource-circulating society. It is positioned as a concrete joint action between the two companies toward achieving the Sustainable Development Goals (SDGs).

Petri dishes are widely used in a variety of settings, including food production facilities, research laboratories, and medical institutions. They play a crucial role in experiments, analysis, testing, quality control, and manufacturing processes, making them indispensable tools in these diverse fields. For our company, Petri dishes are essential across all stages of research, development, inspection, and analysis.

However, Petri dishes are used frequently across a wide range of settings, regardless of specific applications or locations, and are generally discarded after use. In particular, disposable Petri dishes have become the norm due to hygiene and safety considerations. Consequently, their consumption and usage rates are substantial, resulting in a significant amount of waste.

We have long recognized the need to address this situation and promote more environmentally conscious use of resources. Through the implementation of this new recycling process, used Petri dishes will be properly collected and repurposed as recyclable materials, supporting more effective resource utilization. As a result, atect Corp. anticipates a reduction of approximately 20 tons of waste annually, contributing to the realization of a circular economy.

We remain committed to promoting the efficient use of resources and reducing environmental impact as part of our efforts to achieve the SDGs. Moving forward, we will continue to advance sustainable initiatives in our cancer test and test–related research and development, with a strong emphasis on environmental and social responsibility. Our goal is to help ensure a healthy and thriving planet for future generations.
