Waste - Kunnskapsbasen
Sorting of waste has now started at NTNU and our goal is to minimize the amount of waste produced, and to properly sort waste.
The introduction of recycling stations in common areas at NTNU will be gradual.
On this page you can learn how to sort your waste.
Norsk versjon - Avfall
Paper, residual waste and deposit bottles and cans are sorted at recycling stations in the common areas, cafeterias and near the office areas.
The residual waste is emptied once a day, the rest is emptied as needed. All litters are checked every day.
In buildings where recycling stations are not yet located, paper bags is placed near all workplaces.
The residual waste is placed in ordinary waste curves. The waste is collected in containers at each building and is collected by our own transport department on fixed routes.
Cardboard and paper
- Packaging cardboard, newspapers, paperback books, beverage cartons, envelopes (including window envelopes), advertisements, writing paper, periodicals, magazines, etc.
- The paper is collected for recycling into new paper, corrugated board and newsprint.
- In some buildings cardboard and paper are sorted separatly. Contact custodial services if you want cardboard to be collected.
Deposit bottles and cans
- Beverage bottles and cans marked with a deposit symbol ("PANT") are collected and delivered for a refund of the deposit.
- The income from the deposit is spent on Rainforest Foundation Norway (Regnskogfondet)
- What is left when everything that can be sorted has been removed.
- Food waste, porcelain, stoneware, dirty cardboard and paper, ring binders, hardcover books and CDs.
- Hazardous waste, batteries and electrical waste must never be thrown away in the residual waste.
- Residual waste is used for district heating of homes, businesses and institutions in the Trondheim area.
- Sharp objects must be wrapped to prevent personal injury.
For sorting of plastic, glass, metal and electrical or electronic equipment please contact custodial services.
- Packaging that is clean or almost clean, for example plastic bags, chocolate wrappers, potato chip bags, ice cream containers, plastic cups, plastic bottles that do not have a deposit symbol, and plastic wrap. If the plastic is not packaging, discard it as residual waste. Plastic packaging waste is recycled into new plastic products.
- Packaging that is clean or almost clean, for example plastic bags, chocolate wrappers, potato chip bags, ice cream containers, plastic cups, plastic bottles that do not have a deposit symbol, and plastic wrap. If the plastic is not packaging, discard it as residual waste.
- Plastic packaging waste is recycled into new plastic products.
- Glass packaging such as jars and glass bottles without a deposit symbol.
- Glass packaging is sold to glass works, which melt it down into new glass containers. Glass is also recycled into insulation materials for homes and road construction, as well as for building blocks.
- Metal packaging for food and drink (except beverage cans with a deposit symbol).
- Aluminium and steel are sold as raw materials for aluminium foil, cans for food, and bicycles. Steel can be recycled into steel structures in buildings, tools, nails and screws.
- Batteries are defined as chemical waste. Se guidelines for disposal of chemical waste.Never discard batteries as residual waste. This is especially important because batteries contain lead, mercury and cadmium. These toxic metals must go into a closed cycle so that they do not harm humans, animals and nature.
Electrical and electronic equipment
- Cables, accessories for mobile phones and other small electrical equipment. Electrical waste produces hazardous emissions when it is incinerated and must never be discarded in residual waste.
- Large and heavy items must be placed on pallets (eg refrigerator, washing machine, etc.)
- The paper are loaded in the locked waste bins marked "Makuleringspapir". All bins are locked and can only be unlocked by employees in the transportation division. There are black plastic bags in the bins. Emptying are ordered via custodial services. The transportation division brings out the black plastic bag and brings this to combustion. Full plastic bags are replaced with a new one.
- Every faculty and department is responsible for their own hazardous waste. See the page on hazardous waste for more information.
Glass waste from laboratories
There is a collection point for glass waste from laboratories in rooms DU4-147 in Realfagbygget. The glass is brought to the room by the users themselves. The following point must be met:
- The glass waste must be clean and dry.
- The waste must not contain any residues of chemicals or biological material.
- The waste must not smell of chemicals.
If the glass waste is or may be contaminated with chemicals, it must be disposed of in accordance with. procedures for hazardous waste and not placed here.
The waste can be packaged in cardboard boxes. These can have a plastic bag / inner bag. Collection takes place in pallets with karma. In order to achieve good logistics, it is important that the pallet positions are filled up in order, ie position 1 is filled before position 2 is used, etc.
- Wood, stone, concrete and metals should be collect in separate containers outside of each building. The waste will then be delivered for recycling. Contact custodial services if you need to dispose of large amounts of waste.
During summer containers for disposable grills will be placed in Høgskoleparken (Gløshaugen):
- Furniture can be reused using the website Gjenbrukstorget.
- Hand in your old but usable glasses to one of the opticians included in NTNU's purchase agreement. The optician will givs them to the Salvation Army, where they will be put to use in poor countries.
