Changshu Shouyu Machinery Co., Ltd.

Inheriting Italian Craftsmanship, Forging Chinese Strength in Solid Waste Crushing Rooted in Brescia, Italy, in the 1970s, the story of Soyu Machinery began with a waste wood crushing equipment enterprise founded by Mr. Pierluigi. Passed down through three generations of his family, the business accumulated over 40 years of technical heritage in the solid waste crushing sector. In 2009, Mr.Xie teamed up with this veteran Italian machinery enterprise to establish Soyu Machinery – a joint venture based in Changshu, Jiangsu Province. Its founding mission was to introduce Europe’s advanced shredding and crushing technology to China, addressing the industry pain points of over-reliance on imports and poor adaptability of high-end solid waste crushing equipment domestically, and making professional solid waste crushing solutions accessible to more environmental protection enterprises across China and the globe. "Empowering solid waste resource utilization with Italian technology and driving circular economy development through local innovation" is Soyu Machinery’s core mission. Its vision is to become a benchmark service provider in the global high-end solid waste crushing equipment sector, positioning Soyu’s shredding and crushing equipment as the backbone of the solid waste treatment industry. Over more than a decade of dedicated development, Soyu Machinery has achieved remarkable milestones: •From its inception, it pioneered the mass production of four-shaft shredders, filling the market gap for high-end shredding equipment in China; •After rooting in China, it built a professional service team, having cumulatively delivered over 6,000 crushing application cases and exported products to more than 80 countries and regions, emerging as a core supplier in the R&D and manufacturing of shredding equipment. Soyu Machinery adheres unwaveringly to its core values: "Technology as the guide, environmental protection as the core, and quality as the foundation". Inheriting over 40 years of Italian shredder R&D expertise, core components such as cutter shafts and blades are manufactured using imported processes, ensuring the equipment delivers both high shredding efficiency and exceptional stability. Going beyond traditional one-size-fits-all models, its R&D team continuously optimizes solutions based on local needs, creating specialized systems for diverse materials including metals, plastics, and hazardous waste. As a "trusted partner" for customers in solid waste treatment, Soyu Machinery deeply understands the pain points of environmental enterprises: it meets the large-scale material processing demands of leading environmental companies while adapting to the solid waste crushing scenarios of small and medium-sized enterprises. Through end-to-end services – from customized R&D and on-site installation/commissioning to operation and maintenance – Soyu has built an emotional bond with customers centered on "joint environmental protection and win-win cooperation". In terms of social and customer value, Soyu’s shredding and crushing equipment not only enhances processing efficiency and reduces operational costs for solid waste treatment enterprises but also facilitates the recycling of renewable resources such as metals, plastics, waste paper, and wood, driving circular economy development. Its comprehensive technical training programs have also cultivated a large pool of professional talents in the operation and maintenance of solid waste crushing equipment for the industry. Keeping pace with global trends in environmental protection and circular economy, Soyu Machinery continues to refresh its brand narrative, deepening its positioning as a provider of "environmentally friendly solid waste crushing equipment".
