RECYCLING AT THE HEART OF OUR FUTURE

TRENTETROIS

Enhance the Value of Your Metals, Invest in the Future

Rooted in the heart of the circular economy, the Trentetrois sites of the Riva Group collect and recycle ferrous and non-ferrous metals every day, from both private individuals and businesses. Thanks to our strategic locations and the use of multimodal transport solutions, we promote short supply chains, reduce environmental impact, and ensure sustainable resource management.

Your metals will be weighed, sorted, processed, and recovered in compliance with the most demanding industry standards.

Choosing Trentetrois means placing your trust in a reliable partner that controls every stage of the process, from collection to recycling, ensuring the quality of its raw materials and their transformation into new products that serve the community.

Metal recycling is both economical and sustainable.
