Biolan Biowaste Composter

Biolan Biowaste Composter is designed for year-round composting of kitchen waste. The thermally insulated composter with an efficient ventilation system quickly produces compost. Biolan Biowaste Composter has been dimensioned for the biowaste generated by a single family. If Biolan Biowaste Composter is used in the correct manner, the mass will be efficiently composted, which will make using and unloading of the composter more pleasant.

The composter is intended for biodegradable materials only.

Do not place anything in the composter that could impede the composting process or will not turn into compost, such as:

  • Plastic, rubber, glass, leather
  • Chemicals, wood preservatives and disinfectants, paints, solvents, petrol
  • Detergents, washing water
  • Lime
  • Ash, cigarette butts, matches
  • Hoover bags
  • Coloured advertisement paper
  • Large quantities of paper


  • Empty the biowaste container into the composter. Please note that the larger the pieces of waste you put into the composter, the longer it will take for them to disintegrate.
  • If you use biodegradable rubbish bags, empty the content of the bag into the composter and put the bag in separately.
  • Always cover the waste with Biolan Bulking Material. Usuall the proper amount is approximately one-third to half of the amount of new waste deposited in the composter. If the waste is wet, use more of the bulking material.
  • Continue adding more waste to the composter as you generate more waste. Try to add more waste to the composter several times a week. This is especially important during the cold season.
  • Stir in the most recent compost down to some 20–30 cm from the surface. You do not need to mix the compost after every loading. The more bulking agent you use, the less mixing the mass requires.
  • Do not mix the entire compost mass all the way down to the bottom to prevent the already cooled lowermost layers from cooling down the compost mass that is still warm.


  • The Biowaste Composter must be emptied all year round. Unload the composter when it is almost full, more often during the cold season than during the warm season. After the composter has been unloaded, there is more oxygen in it, which will often increase the temperature inside the composter.
  • In the wintertime, only remove a little bit of the compost mass at a time. In the summertime, you can remove more, but always unload at the most half of the compost mass.
  • Open the unloading door (part 5) and remove some of the mass from the bottom of the composter with a shovel.
  • Also clean the area under the seep liquid plate and make sure that there is no blockage in the seep liquid hose.
  • If the mass you removed was very wet, place a couple of shovelfuls of Biolan Bulking Material in the bottom of the composter.
  • Close the unloading door.
  • Press down the mass from the top with the shovel, for example. It will be easier if you start from the corners. Take care not to damage the inlet air channel located in the centre of the composter.
  • Empty the seep liquid container, if necessary.

Choosing correct composter location

Place the Biowaste Composter in a place where you can easily take your waste and unload the composter all year round. Set the composter up on a firm surface at a location with good drainage. Make sure that the composter is level.

The Biowaste Composter includes a seep liquid opening in the bottom left-hand side to drain any excess liquid. Place the composter directly onto the ground so that the soil will absorb any seep liquid. Alternatively, you can collect the seep liquid. If the compost mass is unusually wet, seep liquid may also seep from under the unloading door and from the inlet air valve at the front of the composter. 

Before use

Place the liquid separation plate in the recess located in the bottom of the composter (the seep liquid drain). The purpose of the liquid separation plate is to separate any excess liquid from the compost mass. The plate can be detached and cleaned if necessary.

The Biowaste Composter has a seep liquid opening in the bottom left-hand side to allow any excess liquid to drain from the composter and be absorbed into the ground. You can collect the seep liquid in a container if you like, but this is not mandatory. Remove the rodent shield from the seep liquid opening in the bottom edge of the composter with a screwdriver, for example. Connect a liquid hose, diameter 32 mm, to the seep liquid opening in the bottom edge of the composter. Place the other end of the hose in a container located in such a place that the liquid will flow downhill.

Place a layer of five centimetres (5 cm) of Biolan Bulking Material in the bottom of the composter. Start using the composter. When you are putting waste into the composter for the first time, use more bulking material than recommended – you can reduce the amount later on.
