Waste disposal
Waste, other than burnable and recyclable resources, must be disposed of in ways compatible with the Waste Management and Public Cleansing Act. Where waste product is disposed of by individual research departments, permission must be obtained from the person responsible in each department.
The University is engaged in the detailed sorting of waste. Please ensure that your own room has a container to collect memos, business cards, postcards, wrapping paper and other paper waste. In order to improve the percentage of waste we recycle, we inspect the volume of paper waste in our burnable waste each year.

○Disposing of waste products from experiments
Hazardous wastes (specially-controlled industrial wastes) are collected at each department and regularly collected from all the departments. Collection methods differ at each department. Please inquire to the responsible department. Electronic manifests and administration tables are provided to the responsible personnel of each department. Also, at each time specially-controlled industrial wastes are disposed of.
Regarding separation of wastes from experiments, there are bottles (mutual to domestic wastes), burnable wastes (such as waste plastic), hazardous deposited objects, and non-burnable wastes (mutual to domestic wastes). Please put out waste at the separate collection areas of each department.
○Processing of domestic waste
＊Domestic sorted waste
Bottles, drinks cans, PET bottles, polystyrene, metal waste, non-burnable waste
Put out waste at the separate collection areas located at each department and please be sure to follow the rules.
＊Other waste products
Batteries: Collected in July, or thereabouts.
Fluorescent tubes: Collected in October, or thereabouts.
Machinery and large-scale waste: Taken to collection storage by person responsible in each department.
○Recycling system
Staff can post information regarding items they are willing to give away or loan, or are looking for, on the web page shown below. Search for items using the “Search for recycled items” function, and if an item comes up, you can contact the person listing it and recycle the item effectively. Please use this system whenever possible.
