household hazardous material
Spray cans and lighters used in daily life can be disposed of as business-related general waste. However, if the spray cans and lighters are not properly disposed of before being discharged, they may ignite in the garbage truck. For this reason, the Environmental Safety Center collects used spray cans and lighters as household hazardous waste once a year in batches and outsources their disposal to an external specialist.

Waste fluorescent tubes
Fluorescent tubes contain mercury to emit light, and it is not good for the environment to discharge them as business-related general waste. For this reason, the Environmental Safety Center collects used fluorescent tubes once a year as waste fluorescent tubes and outsources their disposal to an external specialist.

Waste batteries
There are many different types of batteries. Commonly used manganese and alkaline batteries contain zinc, manganese dioxide, and iron. Button batteries contain a small amount of silver. Nickel-cadmium and lithium batteries contain nickel, cobalt and lead, with lead being a particularly harmful chemical. Lead-acid batteries used in batteries also contain harmful chemicals such as sulfuric acid and lead. For this reason, the Environment and Safety Center collects used batteries as waste batteries or lead-acid batteries in batches once a year and outsources their disposal to an external specialist.
