As Germany’s photovoltaic capacity continues to grow, a large number of early-installed PV modules are gradually reaching the end of their operational lifespans. In early 2024, a client from Germany contacted us with a clear objective. They aim to establish a photovoltaic panel recycling production line with a capacity of 1,000 kg / h, in order to provide professional recycling services in the local area and surrounding regions.
The client originally engaged in the recycling of scrap cables and possessed some experience in recycling, but was unfamiliar with the structure of photovoltaic modules, disassembly methods, and environmental standards. They are concerned about the lengthy return on investment cycle for equipment and also hope to achieve efficient processing with limited factory space and power supply conditions. Based on the client’s specific circumstances, we have designed a 1000 kg/h photovoltaic panel recycling project in Germany.
What is the current status of Germany’s photovoltaic recycling market conditions?
Which Recycling Solution Maximizes Value for This PV Recycling Project?
During the technical discussion with the client, For the 1000kg/h Photovoltaic Panel Recycling Project in Germany, we designed both a mechanical system and a solar panel pyrolysis project solution to meet different recovery goals.
This PV pyrolysis technology uses high-temperature pyrolysis to decompose the EVA adhesive layer, significantly improving the separation purity of silicon wafers and glass. Research shows that pyrolysis is more effective than simple crushing in removing organic matter and separating large-particle glass, resulting in higher purity of recovered materials .
The investment cost is lower than that of pyrolysis lines, there is no risk of harmful gas emissions from combustion, the process is mature, and it is easier to obtain environmental permits in Germany.
After weighing the budget and the speed of obtaining permits, the client chose our PV mechanical recycling solution. We reserved an expansion interface for future connection to a solar panel pyrolysis recycling line, allowing for future upgrades if material purity requirements become higher.
What is the primary process flow for the 1000 kg/h photovoltaic panel recycling project in Germany?
To meet the requirements of our German clients, we designed a single-glass photovoltaic panels disposal project featuring modular processes and a fully enclosed eco-friendly system. The entire photovoltaic panel recycling production line features a compact structure, low energy consumption, and high processing efficiency. Therefore, it is suitable for Germany’s stringent environmental regulations and industrial safety standards.
Pre-processing
Photovoltaic modules enter the system via a belt conveyor. First, the semi-automatic frame remover separates the aluminum frame. Subsequently, the glass remover uses mechanical force to break the tempered glass, allowing for the preliminary recovery of large-particle glass and reducing the load on subsequent crushing.
Multi-stage Sorting
Magnetic separation machine
Magnetic separation machine: Removes iron filings and ferrous metal debris from the frame.
Eddy current separator
Eddy current separator: Separates non-ferrous metals, mainly aluminum and copper.
Gravity separation equipment
Gravity separation equipment: Separates light materials (crushed plastic from backsheets) from heavy materials (glass and metal mixture).
Electrostatic Separator
Electrostatic Separator: Extracts copper and silver from mixed metal powders, delivering >99% recovery of precious metals for maximum profitability.
Environmental Protection System
The project is equipped with a baghouse dust collector (capturing fine dust with an efficiency of >99.9%) to ensure that exhaust emissions meet German TA Luft (Technical Instructions on Air Quality Control) standards. The process is entirely dry and physical, achieving zero wastewater discharge.
How Profitable Is Copper Recovery in the German Market?
During the equipment selection phase, the client specifically focused on the recovery of t. Because copper has a high unit price and is a key factor in shortening the ROI cycle.
Txawm li cas los xij, if the copper is sold directly to smelters in Belgium (e.g., Umicore) or specialized metal refineries, they offer higher purchase prices for high-purity copper because they can directly process it . Our electrostatic separation system increases copper purity to over 99%, enabling the client to bypass local intermediate dealers and sell directly to large smelters for better prices.
Customer Benefit: Recovering only copper can generate €264 to €360 in daily revenue. Combined with aluminum (accounting for approx. 10%-15% of total weight) and glass revenue, the payback period for the equipment can be significantly shortened.
Why Did Our German Client Ultimately Choose Our Solution?
After evaluating multiple equipment manufacturers, the client ultimately decided to partner with us. The core reasons are as follows:
