What is the Urban Mining Business?
Sustainable Recycling Utilizing Urban Mining
Domestic Recovery and Recycling of Precious and Rare Metals
The term “Urban Mining” has become widely recognized, and the need to recover precious metals and rare metals contained in circuit boards, mobile phones, and IC scrap is increasing.
For over 20 years, Bio World Co., Ltd. has been purchasing these precious metal scraps from both domestic and international clients and conducting resource recycling within Japan, rather than exporting them overseas.
Benefits of Domestic Recycling
The Importance of Environmental Protection and Compliance Adherence
Reasons Why Domestic Recycling is Preferred
In recent years, more people have become increasingly aware of the importance of environmental protection and strict compliance adherence.
At the same time, the number of customers who support our philosophy of domestic processing is growing. Additionally, international clients highly value Japan’s advanced recycling technology and environmental protection efforts, leading to a rapid increase in inquiries.

Leveraging Japan’s Recycling Technology for a Sustainable Future.
Meticulous Hand Disassembly Method
Precision Recycling Through Hand Disassembly
The Reason We Emphasize “Hand Disassembly”
At our company, we principally disassemble all entrusted equipment and devices by hand.
While many other businesses opt for bulk crushing and mechanical sorting, we deliberately avoid these methods.
This approach is based on our commitment to efficiently recover valuable resources—especially trace amounts of precious and rare metals—contained within equipment and devices.
In practice, even high-performance mechanical sorting systems often result in significant material loss, despite their advanced capabilities.

Manual Preprocessing: The Most Efficient Recycling Method!
Social Contribution and Safety Management
Hand Disassembly × Support for Employment of People with Disabilities

Contributing to Social Welfare Through Recycling
Our “Utsunomiya Recycling Center” and “Machida Stockyard” are certified facilities audited by the Ministry of Economy, Trade and Industry (METI) and the Ministry of the Environment.
Furthermore, the hand disassembly process, an essential part of recycling, is carried out by individuals trained at employment support facilities for people with disabilities.
The hand disassembly fees we pay directly contribute to the income of individuals with disabilities, thereby supporting social welfare. Additionally, we offer relatively higher wages compared to other tasks, which has been highly appreciated by both the facilities and the workers.
A positive cycle of Disability Employment × Environmental Protection × Recycling!
At our facilities, we operate in strict compliance with legal regulations, ensuring rigorous management of personal information and minimizing environmental impact.
