They were installed to help the project in Halandri that, as part of Waste4Think, is testing techniques of energy valorisation. Now, they will stay in case there might be new requests, and so that families with children or older people who need nappies can use them.
Starting in January, several collection bins were installed in Zamudio with the purpose of collecting used nappies (inside tightly closed bags) so that they could be sent to Halandri (Greece). Zamudio collaborated this way with the Greek project that, in the context of the Waste4Think program, is testing new techniques of energy valorisation of this kind of waste, in order to turn them into biofuel. The local council wishes to thank citizens for their active collaboration with this objective, which has helped the research that is being carried out in the European project in which Zamudio is involved along with three other European cities.
For the time being, there will be no need to send more nappies to Greece, but the bins will nonetheless stay in the municipality so that new requests that might come from Halandri can be met.
Besides, their presence will allow separating this kind of waste from others; this way, in social justice, if taxes are calculated according to the waste generation rate, families with children or older members using nappies will not be penalised. This was, in fact, one of the issues that arose in the workgroups that discussed waste generation and tax calculation methods that take this rate into account and which are known as Pay As You Throw (PAYT) systems.
The use of one specific bin for this kind of waste prevents nappies from being taken into account when keeping track of the collection bins aimed at ‘rest waste’, the number of times that these bins are opened and the weight of the waste that is thrown inside them.
At the beginning, and as long as there are no more needs in the Waste4Think project, this material will be delivered for energy valorisation through incineration, in the same way that the rest fraction is.
