PV Panel Recycling Service

We provide intermediate treatment service to recycle discarded PV panels. At Matsuyama Factory in Ehime, Japan, an automatic PV panel disassembly line is installed. The line separates glass from other materials without crushing, applying the “separation method using heated blade,” our own technology. Recycling of glass becomes difficult when metals mix with it, however our original method enables an efficient recycling as no metals exist on the separated glass.

Achievement so far for intermediate treatment of PV panels

Total:    25,114* panels treated 

* As of April 30, 2020

So far, we have treated 25,114 panels. The separated materials are handed over to the recycling companies, and we are putting maximum efforts to recycle discarded panels.

Respective equipment and disassembly process

In discarding PV panels, proper processing is required, as they include toxic materials like lead.

What is the separation method using a heated blade?

ホットナイフ分離法

In this method, a blade heated to 300℃ melts EVA layer to separate glass from other materials.
We have achieved the total recycling of glass and metals by utilizing our knowledge and technology accumulated through the development, manufacture and sales of PV module manufacturing equipment.  This method is highly evaluated as an effective and economical processing method in the industry.
