Technical Analysis: Why Blade Mills Fail on PCBsDiscover the “Screen Paradox,” overheating issues, and why Impact technology outperforms traditional methods.

The processing of printed circuit boards (PCBs) is today one of the most complex challenges in recycling engineering. Unlike other types of WEEE, electronic boards are a particularly difficult composite material: a fiberglass-reinforced resin matrix (FR-4) that encapsulates precious and industrial metals such as copper, tin, gold, and palladium.

Recent reports, including influential insights from Il Sole 24 Ore, highlight a definitive trend: solar energy is experiencing "vertiginous growth," cementing its status as the most convenient and cost-effective energy source globally.This massive acceleration in installations is great news for the planet, but it brings an inevitable industrial challenge: The "Solar Tsunami."

In 2025, solar overtakes coal for the first time. But the “skyrocketing growth” in installations demands an immediate industrial solution for end-of-life management.

The market for recycling Waste Electrical and Electronic Equipment (E-Waste / WEEE) is no longer just about disposal. The challenge of modern Urban Mining is extracting secondary raw materials with "ready-to-furnace" purity levels, while keeping operational costs under control.

While the recycling industry continues to debate the limits of first-generation delamination technologies, Stokkermill Solar has already moved ahead.With over 30 operational plants worldwide and two new strategic installations launching this month in Northern Italy and Sardinia, the company is redefining Integrated Mechanical Delamination, making traditional static systems obsolete.‍

The US solar market is booming, but a massive wave of End-of-Life (EoL) panels is approaching. For waste management operators and scrap processors, the question isn't just if you can recycle them, but how profitably you can process mixed streams at high volume.

The story of how Italian technology is changing the future of photovoltaic recycling

In solar panel recycling, the quality and concentration of the recovered silicon are key indicators of a plant's efficiency and sustainability.

Innovation arises when we decide to look at things from a different perspective, without following established paths. In economics, this attitude contrasts with the concept of “path dependence,” according to which past decisions heavily influence future ones, even when conditions change.

With over 40 years of experience in designing material recovery machinery, Stokkermill has developed a line of combined plants capable of treating photovoltaic solar panels and electronic waste (WEEE) with the same efficiency.

In recent days, the Stokkermill team visited our partners in Mexico, taking a step that is not only commercial, but also cultural and human. This collaboration with Stokkermill México is not just an expansion of our international presence: it is concrete proof of how innovation and sustainability can unite countries, people, and visions in a single global project.

On September 10, 2025, the international magazine Recycling Inside published the article “Solar Panel Recycling: Stokkermill Technology Turns Aluminum into Furnace-Ready Value,” dedicated to Stokkermill Recycling Machinery's solutions for recycling photovoltaic panels.

The compact Stokkermill K750 granulator, now equipped with high-end ABB motors, represents a significant step forward in the industrial recycling sector.

Stokkermill, in collaboration with Cela Machinery, has created a customized high-tech plant for Old Metals for the recovery of copper and metal powders from complex waste, with innovative and sustainable solutions.
