Recyclables collection and separate collection of biowastes in the Mühldorf am Inn and Altötting districts
Existing recyclables collection systems were examined and options for increasing biowaste quantities already collected separately were shown. In most cases, this involves optimising existing recyclables collection systems, which were compared with a system changeover to a mixed recyclables bin.
From the recyclable material potential analyses not only classic recyclables such as paper and metals were determined but also the fractions of the native organic wastes and from these the expected composition of a biowaste bin.
$ 11 Para. 1 of the new Recycling Management Act ("Kreislaufwirtschaftsgesetz" - KrWG) requires separate collection of biowastes by 01.01.2015 at the latest. Biowastes from private households are subject to a transfer obligation, provided no recovery takes place on the household's own properties in the form of its own composting. The disposal providers under public law are therefore the addressees of the obligation of separate collection.
The citizens of approx. 80 % of the disposal providers under public law (örE) in Bavaria are connected to a separate collection system for biowaste. The degree of connection varies, depending on the organisation of the collection system and the fees system, from < 5 % of the residents of one disposal provider under public law (örE) to up to > 70 %. Many local authorities are now faced with the question of whether they have to introduce separate collection under the wording of the recycling management law (KrWG) or whether separate collection of green gardening waste, significant in terms of quantity, take into account the KrWG or indeed whether low degrees of connection of already introduced separate collection still or no longer comply with the law. bifa, together with AU Consult, examined this in the Mühldorf am Inn and Altötting districts.
Before separate biowaste collection is introduced it is important to include the following aspects from the current discussion and especially from the new KrWG:
Self-composting of biowastes continues to be allowed, however, the biowastes are subject to a duty to hand them over to the public waste management organisations.
Reference is explicitly made to the technical possibility and economic acceptability of the introduction of separate collection. It is possible to weigh up the overall situation with regard to ranking and high-quality of the recovery measures after the measure has been checked. The acceptance of separate collection and the self-composting rate can also be taken into account.
These issues are examined for the specific collection and recovery system in its actual state compared to new or optimised separate collection. Not only the different treatment process options play a role here, but also the overall system for green gardening waste and biowastes is mapped. The expected composition of the biowaste bin from an analysis of the recyclable material potential provides reliable basic data.
On the basis of the actual treatment and recovery facilities and disposal routes, not only are life cycle assessments performed but also the economic component is also examined. Finally, the results are related to the KrWG aspects listed above, so that the respective disposal provider under public law has a basis for forming an opinion on the topic of the separate collection obligation.
