How to Separate Waste Materials (for those who take out waste materials among teaching staff and graduate students - ‘Kanazawa University Regulations on Waste Management –No.1310-5)
Approved by the Environment Committee, 24 June 2012
Facility and Environment Planning Committee, 31 March 2020
I Types of waste: Combustible, Non-Combustible (landfill), and recyclable
In compliance with the rules, everyone is to separate the waste that they generate, keep it in the specified manner and when the particular waste is accumulated to a certain amount,take it out to the designated place on the designated date.
Throwing away waste anywhere other than the specified place is considered illegal dumping which is a punishable offense. Also try to keep waste collection points clean and tidy.
The University manages only the waste generated from the activities of the University. Bringing in waste from outside (home etc.) is not allowed.

The person who generate the waste should contact the outsourcing manager in the relevant department/faculty, stating the necessary details about the waste he/she wants
to dispose of.
(2)
The outsourcing manager should check the necessary documentation provided by the waste generator, check the item if necessary, and determine whether the item needs
outsourced service or not. Items classified as Specially Managed Industrial Waste need confirmation by a local Specially Managed Industrial Waste supervisor. If it is difficult
to determine, consult the Environment Management Office, Facilities Department or equivalent office.
(3)
The outsourcing manager should consult the Environment Management Office, Facilities Department (or equivalent office in the University Hospital) and investigate
whether there are any appropriate outside contractors who can handle such waste material.
(4)
The outsourcing manager should complete the necessary documentation and fax it to the Environment Management Office, Facilities Department (or equivalent officein the University Hospital).
(5)
The selection of the contractor should be conducted at the Facilities Department .
(6)
The outsourcing contract manager should select and assign a contractor who holds the license from the governor or the mayor’s office of the municipal government, tocollect, transport and treat the waste (hereinafter referred to as “the selected contractor”).
(7)
On selection, the outsourcing contract manager should inspect the license as well as the treatment facility of the contractor.
(8)
The person discharging the waste and the outsourcing manger should attend when the waste material is collected by the selected contractor, check the identity of thecontractor (checking the authorization sticker at the vehicle door etc.), as well as the state of the waste, whether there is any risk of spillage or leakage during the transportation.
The person discharging the waste should then create an Industrial Waste Management Sheet (manifest) and provide it to the selected contractor with the consignment.
(9)
The Industrial Waste Management document is to be kept at the Environment Management Office, Facilities Department.
(10) The outsourcing contract manager, the outsourcing manager and the person responsible for discharging the waste should confirm whether the treatment of the waste isgoing to and was properly conducted, by written correspondence with the contractor or visiting the treatment site, as appropriate.
(11) The outsourcing contract manager should create an Industrial waste outsourcing document, with contracts and invoices filed by each academic year and keep them for
5 years.
(12) The outsourcing contract manager, the person responsible for discharging the waste, the Specially Managed Industrial Waste manager and the outsourcing manager
should investigate and take necessary measures if the selected contractor were to be found in the following situation:-The selected contractor fails to return the Industrial Waste Management Sheet within the designated period.
- It is judged that the industrial waste or the Specially Managed Industrial Waste has not been processed properly.
