Pilot actions to optimize separate collection or special treatment of food waste
Introducing separate collection of organic waste in Poland (Wroclav) (PA 16)
In Wrocław, like in most other Polish municipalities, from 2013 the municipality has taken control over the municipal waste management system. Paper, glass, plastic and metals are collected separately. When it comes to organic waste, only garden waste is collected in low-rise areas, in bags. In Poland the latest by the end of the year 2021 all municipalities have to introduce separate collection schemes for biowaste. In the recent ordinance on methods of selective collection of specific waste streams (from 29.12.2016) it is stated that biodegradable waste, specifically biowaste, should be collected separately in bins. Municipalities should imply this when starting new collection contracts, the latest by July 1st, 2021. Wrocław recently tendered long term collection contracts, so a city-wide separate collection of biowaste will likely be introduced by 2021 only.
Goal of the Pilot Action is the implementation of a kitchen waste collection scheme from households on a small scale. As an arbitrary size the pilot will be implemented at 1000 inhabitants in low-rise and 1000 inhabitants in high-rise areas.
Households concerned will be informed at the beginning of the pilot and will receive means for temporary storage of the kitchen waste.

Goal of the Pilot Action is the implementation of a kitchen waste collection scheme from households on a small scale. As an arbitrary size the pilot will be implemented at 1000 inhabitants in low-rise and 1000 inhabitants in high-rise areas.
Households concerned will be informed at the beginning of the pilot and will receive means for temporary storage of the kitchen waste.
Foreseen means of temporary storage:
- inside homes: a small container for segregated collection of kitchen waste and/or biodegradable bags
- outside homes:
- 1100 l containers for 60 persons in high-rise areas
- 120 l containers for each household in low-rise areas (or evt. 80 l bags) for combined kitchen and garden waste collection
- 1100 l containers for 60 persons in high-rise areas
Monitoring:
- amounts collected in the high- and low-rise areas: continuously (weekly/bi-weekly)
- composition of residual waste and separately collected biowaste: four times per year
Utilisation of organic fraction in residual waste for biogas production
With the Pilot Action 14 a concept will be developed and tested where organic compounds are solved out from residual waste. To separate organic from residual waste an additional aggregate has to be defined (by a feasibility study) and installed in the running waste sorting plant in Innsbruck. This organic material can therefore be used as substrate for digesters in waste water plants in order to produce biogas / biomethane.
The Aim is to use organic waste locally for energy production and to save nutrients (e.g. Phosphor) instead of burning them as part of residual waste.
Stakeholders involved are from sector 6 and Abfallbehandlung Ahrental GmbH (AAG). In cooperation with ATM.
Next steps
Within the next months a technical feasibility study will be undertaken to define the optimum technology. This will be implemented as an aggregate into the waste-sorting plant and the test run will start in 2018.
