Business
Sanwa Yuka Kogyo, founded in 1970, is an Environment-Related Business specialist group (8 consolidated subsidiaries). Under the concept of "creating environmental needs," the company collects industrial waste—such as waste solvents, waste acids, and useful metals—discharged from manufacturing customers' factories, and centers its operations on the Reuse Business and Recycling Business, which perform intermediate disposal and resource recovery using chemical methods such as distillation, solvent extraction, and neutralization. In addition, the company operates a total of five businesses, including chemical product manufacturing and sales (for automotive and electronics applications), automotive oils and cleaning agents, and the Engineering Business (including PCB-containing waste treatment). Its distinguishing feature is a circular-economy-type business model that seamlessly covers everything from product manufacturing and sales to the recycling, logistics, and quality assurance of used waste. Its main customers are manufacturers in the automotive, semiconductor, and electronic components industries. The company operates six plants in Aichi, Ibaraki, Wakayama, and Osaka, along with four sales offices nationwide, with a workforce of 469 employees.
Business Model
Revenue is built on two pillars: "processing fee sales" (service income from the collection and intermediate treatment of industrial waste) and "general sales" (product sales income from recycled products, chemicals, oils, and similar items). In FY2026 (ending March 2026), processing fee sales were ¥5,524 million and general sales were ¥14,739 million. The structure whereby the company receives processing fees when accepting waste and then earns additional revenue by selling the recycled products it produces contributes to stable profit margins. Fund efficiency is also optimized through centralized management of group funds via a CMS (Cash Management System).
Company Strengths
The company possesses a vertically integrated system that enables it to complete, within its own group, everything from product manufacturing and sales to the collection, intermediate disposal, resource recovery, logistics, and quality assurance of waste products. Its diverse chemical processing technologies—including distillation, solvent extraction, neutralization, and kneading—combined with its quality, environmental, and safety management systems certified under ISO9001, ISO14001, and ISO45001, serve as differentiating factors versus competitors.
The company has a unique business structure that allows it to earn revenue twice from a single waste stream: it receives disposal fee income when accepting industrial waste, and then generates additional revenue by selling the recycled products derived from that waste. In FY2026 (ending March 2026), the gross profit margin reached 28.4% (gross profit of ¥5,752 million divided by net sales of ¥20,263 million), with this dual-revenue model underpinning the company's profitability.
The company has a track record of continuously expanding its network of sites by combining M&A, joint ventures, and the establishment of new companies, including the establishment of Sanwa Nankai Recycle (Wakayama) in 2018, the establishment of Sanwa Sakai Recycle in 2019, the establishment of Sanwa Material Solutions (Kitakyushu) in 2024, and the acquisition of A&H Japan (Osaka; precious metal recycling) as a subsidiary in October 2025.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥17,367 million in FY2023, up from ¥15,538 million in FY2022, then remained sluggish at ¥15,633 million in FY2024 and ¥16,040 million in FY2025, before sharply recovering to ¥20,263 million in FY2026 (up 26.3% year on year). Operating profit also improved significantly from a trough of ¥836 million in FY2025 to ¥1,543 million (up 84.6% year on year), with the operating margin rising from 5.2% to 7.6%. The main drivers of the recovery were the expansion of the Reuse Business (revenue of ¥7,239 million, up 82.2% year on year) following the consolidation of A&H Japan as a subsidiary, and the expansion of the Engineering Business (¥1,559 million, up 63.7% year on year) driven by an increase in PCB treatment projects. On the other hand, some businesses were affected by external conditions, such as the Chemicals Business, where demand for electronics applications fell short of plan (up only 1.0%), and the Automobile Business, which struggled with product sales (down 1.3%). Shareholder return indicators also improved, with ROE at 8.4% (versus 4.9% in the previous fiscal year) and EPS at ¥248.16 (versus ¥136.98 in the previous fiscal year).
Growth Strategy
Realizing Grand Vision 2030 through the development of recycling facilities for semiconductors and batteries and expansion of business domains via M&A
Subsidiary Sanwa Material Solutions Co., Ltd. is constructing a recycling plant in Kitakyushu City. The plant will capture demand for recycling of used chemicals, which is expected to increase with the growth of the electronics sector, including semiconductors, batteries, and electronic components. Construction in progress has reached ¥3,218 million, indicating that investment is now in full swing.
In October 2025, the company acquired full ownership of a metal recycling company based in Osaka City for ¥700 million. By integrating the acquired company's separation, recovery, and refining technologies for precious metals and rare metals with the group's own collection and sales network, the company aims to address domestic resource circulation needs in the electronics sector. The six-month contribution in the second half of FY2026 (ending March 2026) drove an 82.2% increase in Reuse Business sales, and expanded contribution is expected from FY2027 (ending March 2027) onward, when a full-year contribution is anticipated.
Leveraging know-how accumulated in PCB-containing waste treatment, the company aims to capture demand for the renovation and demolition of chemical plants and other facilities, which is expected to increase going forward. In FY2026 (ending March 2026), sales reached ¥1,559 million (up 63.7% year on year), driven by an increase in projects acquired ahead of PCB treatment deadlines. However, delays in the start of large-scale demolition projects mean that continuously securing new projects remains a challenge.
The company has clearly stated its policy of actively pursuing M&A and business alliances to supplement resources needed for business growth. The subsidiarization of A&H Japan is one such achievement. Against the backdrop of resource procurement risks stemming from heightened tensions in the Middle East and the need to strengthen ESG/SDGs initiatives, the company is accelerating its response to domestic resource circulation needs.
