A large number of photovoltaic modules will reach their retirement period within the next 10 uchun 25 yillar. How to handle these waste modules containing high-value materials such as glass, kremniy gofretlar, silver paste, and aluminum frames has become a focus of industry. The emergence of PV recycling technology not only enables the effective recovery of valuable resources but also prevents environmental pollution, thereby realizing a green, low-carbon circular economy.
What are the technical approaches for PV recycling?
Photovoltaic modules primarily consist of glass, kremniy gofretlar, orqa varaqlar, EVA adhesive, metal frames, and conductors. The tight bonding between these layers poses challenges for recycling. Shuning uchun, a PV recycling technology corresponds to different separation methods and objectives.
The mechanical method is one of the most mature and fundamental recycling approaches at present. The core principle involves physical methods such as quyosh panelini demontaj qilish uskunalari, maydalash, and sorting to achieve the initial separation of glass, metal frames, va kremniy gofretlar.
This method features a simple process flow, low energy consumption, and no secondary pollution. Biroq, it has limited effectiveness in removing EVA adhesive layers, and the recovered silicon purity is not high, which is suitable for primary recycling.
The PV piroliz texnologiyasi involves heating EVA in an inert gas atmosphere to decompose it, thereby releasing the silicon wafers and glass. Quyosh paneli piroliz loyihasi yechimi effectively removes EVA residues, yielding silicon wafers of high purity.
YUSHUNXIN PV recycling technology employs advanced low-temperature pyrolysis processes to effectively reduce energy consumption and emissions while maintaining high recovery rates. It is more efficient and eco-friendly than traditional processing methods.
The chemical method employs environmentally friendly solvents or acid-base solutions to dissolve EVA or backsheet materials, and then separates silicon, stakan, and metal components.
This method preserves the integrity of silicon wafers and achieves high extraction rates, which is ideal for enterprises with stringent material purity requirements. With the growing adoption of green chemistry, the use of biodegradable solvents makes this process safer and more eco-friendly.
In actual production, many enterprises combine multiple processes. Masalan, it first removes the frame and junction box by mechanical means, then eliminates EVA through pyrolysis or chemical methods, and finally extracts metals such as silver and aluminum in wet metallurgical processes.
Can these processes recycle different types of modules?
Photovoltaic modules are of various types, including monocrystalline silicon, polikristalli kremniy, and thin-film cells. The differences in their structures determine the suitability of recycling routes. YUSHUNXIN quyosh panelini qayta ishlashni boshqarish features a modular and intelligent design. The equipment can automatically identify module types and matches optimal process parameters, which supports flexible combinations of PV recycling technology.
What are the key recycling considerations for PV materials?
As PV materials differ in primary valuable substances and pollution risks, recycling emphasis varies accordingly.
EVA and Backing Materials
EVA and backing materials are mostly polymers that can produce fuel oil or reusable chemicals through pyrolysis or chemical recycling.
Metal Frames and Wires
Recycling companies can directly recycle aluminum frames and copper wires through mechanical dismantling. Automatic dismantling equipment significantly reduces labor costs and increases processing speed.
