Shredding Engineering Since 1982

Satrind was born from the founders’ direct experience in the design and production of industrial shredders, in a market—especially in Italy—that was then in its infancy. The choice was clear from the beginning: specialize in a niche technical sector, build robust and reliable machines, grow with the market without ever abandoning the company’s core business. A vocation that has remained unchanged for over forty years.

The first twin-shaft shredders with electric motors—10 and 15 HP series—were developed and produced entirely in-house at the Cornaredo (Milan) facility. The control system was based on electromechanical control panels, with some process parameters managed by an electronic board: a technical solution that, in its analog version, is still present in our control panels today.

The company grows and specializes, expanding its range with the first 2- and 3-shaft models and consolidating its presence in the recycling sector. The first shredders with 50 HP hydraulic motors are produced. Control panels remain electromechanical, with a dedicated electronic board for managing reversals.

The organizational structure expands: new technicians and operators join, and the founders’ roles evolve from operational to managerial. By the end of the decade, the need for structured reorganization emerges, leading to the introduction of UNI EN ISO 9002:1994 certification—a process that took two years. Since then, quality certification, in all its evolutions, has never left the organization.

In 1996, the first Machinery Directive 89/392/EEC came into force, establishing essential health and safety requirements for the design and construction of machinery in the European Union. Shredders also had to comply: for Satrind, this was a further incentive to invest in technical expertise and structured design processes.

Satrind moved to its new headquarters in Arluno (Milan), driven by production and organizational needs: more space, more employees. The market was no longer just Italian and European: it was now global. The range expanded with shredders of increasing sizes and power—up to 400 HP—and with increasingly complex solutions.

It was in this decade that a fundamental awareness matured: the shredder alone was no longer sufficient to solve the customer’s problem. The first complete shredding lines were born, starting with tire lines and, at the end of the decade, lines for shredding hazardous waste in inert atmospheres. Control panels became digital with the introduction of programmable logic controllers (PLCs).

On the regulatory front, the Machinery Directive 2006/42/EC came into force, imposing high health and safety standards and requiring CE marking, ensuring the free movement of products in the EU. Meanwhile, the introduction of the euro strengthened the single European market—central to the company—but the subprime mortgage crisis at the end of the decade severely impacted the market.

Internationalization strengthens with a network of dealers and distributors in over 40 countries. Satrind becomes SatrindTech. The range expands with large-capacity shredders and on-board solutions compliant with the Marpol 73/78 Convention, the main international treaty for the prevention of marine pollution by ships.

The 4-shaft shredder range is developed—first 60 HP, then 120 HP—equipped with a screen for controlled selection of output material. An innovative automatic gearbox called M/AWG is introduced for electric motors, achieving performance comparable to higher-power hydraulic motors. Digitalization of industrial processes drives the adoption of PLCs as a production standard, definitively replacing analog electronic boards. The Industry 4.0 paradigm becomes an important driver of development for the Italian market.

SatrindTech is today a reference point in shredding engineering, with a team of specialized technicians who design custom solutions for the most demanding applications, from manufacturing to waste-to-energy.

Customization of shredding lines is now the norm. Lines for hazardous waste, also developed under the ATEX Directive 2014/34/EU—which regulates the marketing of equipment and protective systems intended for use in potentially explosive atmospheres—require demanding engineering and specific expertise that SatrindTech has developed over time.

On the regulatory front, preparations are underway for the new Machinery Regulation 1230/2023, which introduces cybersecurity requirements and requires manufacturers to adopt new systems to ensure the integrity of hardware and software in control systems. At the same time, Transition 5.0 is steering production processes toward high energy efficiency models, in continuity with the path initiated with Industry 4.0.
