INDUSTRIAL WASTE

Fluorescent Lights and Dry Cell Battery Recycling

We hope to achieve our zero-emission goals, specifically through recycling poisonous mercury-containing waste.

Let HAMADA properly deal with the mercury contained in fluorescent lights and dry cell batteries. We carry out clean processing using our patented special crushing machine. The crushed fragments and dry cell batteries are then transported to contracted processing companies and recycled as mercury and glass materials.

In October, 2013 an international treaty on mercury was adopted. Under this treaty, companies are required to undertake proper disposal of mercury-containing waste. With a long history of handling mercury-containing fluorescent lights and dry cell batteries, we are ready to take your consultations.

Used Fluorescent Lights

As an agent of Nomura Kohsan Co. Ltd.-the only company which can recycle mercury in Japan-we offer appropriate handling of fluorescent lights. Using our very own special crushing machine (patent No. 4311273), we crush the light bulbs and collect the mercury within at Nomura Kohsan's Itomuka Plant after fractionate processing. In order to realize zero-emission recycling, the pieces and glass are processed for reuse as glass wool. (Recycling rates : Used dry cell batteries 100%・Fluorescent lights more than 95%)

Process for Recycling Used Fluorescent Lights

Steps 1 to 5 are followed when processing and recycling fluorescent lights.

1. Discharge

You can store fixed amounts of used fluorescent lights.
2. Collection and Transport

You can ask collection and transporting companies to ship your fluorescent lights to us. Or you can let us collect and transport them for you.
3. Intermediate Treatment (Crushing)

By using our originally-developed fluorescent light crusher, fluorescent lights can be crushed into cullet, which is more easy to recycle. The glass is then captured and stored directly in drum containers. A special filter is used to absorb the mercury vapor locked inside the fluorescent lights and only clean air is emitted.

4. Secondary Collection and Transport

After a specified amount of crushed fluorescent light pieces have been stored, they will be transported to Nomura Kohsan's Itomuka Plant in Hokkaido using Nippon Express and JR Freight.
5. Secondary Intermediate Treatment (Roasting)

After being washed and roasted, mercury is collected and refined for reuse. The glass pieces are dried and recycled as materials for glass wool.

Used Dry Cell Batteries

As with fluorescent lights, you can leave the zero-emission recycling of mercury-containing dry cell batteries to us. After transferring and storing the dry cell batteries at our factory, we ship them to Nomura Kohsan's Itomuka Plant for processing, and collecting the mercury, iron, zinc, and manganese for reuse.
Please aware that we might refuse small amout of industrial waste bringing to our site.

Process for Recycling Used Dry Cell Batteries

Used dry cell batteries are sent via HAMADA for final treatment at Nomura Kohsan Co. Ltd. Please view the process below for details.

1. Discharge

You can store fixed amounts of used dry cell batteries.
2. Collection and Transport

You can ask collection and transporting companies to ship your dry cell batteries to us. Or you can let us collect and transport them for you.
3. Transfer and Storage

At our recycle center we transfer and store batteries in drum containers.

4. Secondary Collection and Transport

After a specified amount of dry cell batteries have been stored, they will be transported to Nomura Kohsan's Itomuka Plant in Hokkaido using Nippon Express and JR Freight.
5. Intermediate Treatment (Roasting)

After being washed and roasted, mercury is collected and refined for reuse. Other metals are broken apart and separated into iron, zinc, manganese, etc.
