The waste facilities in Heka’s buildings have separate containers for biowaste, paper, paperboard, glass, metal, plastic and mixed waste. When you sort your waste correctly, you are doing a favour for yourself, your neighbours and the environment. 

There are many good reasons for sorting your waste:

  • The collection of sorted waste is cheaper for the property than that of mixed waste. Careful sorting reduces the cost of waste management, which contributes to tenants’ rents. 
  • Recyclable waste sorted into the correct waste bins ends up for recovery, for example, as raw materials in industry. You can save natural resources with small everyday actions. 
  • Improperly sorted waste and large items, such as furniture and electronics, discarded next to waste bins cause additional cleaning costs, which are also reflected in rents. 
  • Hazardous waste is what the name suggests. Batteries, accumulators, energy-saving light bulbs, paints, solvents and New Year’s tin are a threat to health and the environment when they end up in the wrong place. Learn how to safely dispose of hazardous waste.

HSY’s waste guide at helps with sorting problems.


Biowaste is organic, decomposable and solid material, such as: 
•    leftovers and food waste
•    coffee filters and tea bags
•    vegetable parts and potting soil
•    bones and fish bones
•    solidified grease (liquid grease must not be disposed of in biowaste!)
•    soft paper, such as kitchen towels, paper napkins, tissues 
•    wood-based animal bedding materials.


    Paperboard waste includes paper, paperboard and cardboard packaging such as: 

    • milk and juice cartons
    • cereal and biscuit packages and other carton packages
    • cardboard boxes 
    • paper bags
    • egg cartons
    • empty kitchen towel and toilet paper rolls.

    Flatten the packages to save space or pack them tightly inside each other. 


    Waste paper includes the paper that arrives through your letterbox and writing and printing paper, i.e. 

    • newspapers and magazines
    • adverts
    • printer paper and envelopes
    • paperback books and hardcover books without covers.


    Coloured and clear glass bottles and jars may be placed in the glass waste container. Do NOT put drinking glasses or glass cookware, porcelain, window glass or mirror glass into glass waste. These are mixed waste. 


    Metal waste includes metal packaging and small metal objects, i.e.

    • food and beverage cans
    • aluminium tins and foil
    • metal lids and caps
    • metal casings of tea lights
    • empty and dry paint cans
    • empty aerosol cans. 

    Larger metal objects, such as bicycles, are sorted as scrap metal. Learn how to dispose of large objects.

    Plastic packaging

    Plastic packaging waste includes:

    • empty plastic packaging for food, such as yoghurt containers, butter tubs or packages for cold cuts, cheese and convenience food
    • empty plastic detergent, shampoo and soap bottles
    • plastic carriers, bags and wrappings
    • empty plastic bottles, canisters and jars, preferably flattened; caps and lids detached.

    Do not put plastic packages made of different types of plastics inside each other. Nonetheless, you can collect different types of plastic packaging in the same plastic bag.

    Mixed waste

    Only put waste that cannot be recycled separately in the mixed waste container. This includes, for example: 

    • cleaning waste (dust, sand, debris)
    • incandescent light bulbs
    • nappies, sanitary pads, cotton wool
    • plastic (if the property does not have plastic waste collection)
    • porcelain, ceramics, mirror or window glass
    • ash and cigarette butts
    • liquid grease packed in a bottle
    • gift wrapping paper
    • cat litter
    • broken textiles and shoes.
