D1.3 Report and main conclusions of the biowaste collection

One of the main challenges of urban biowaste management is to integrate a valorisation system in a city context, and to recover strategic products with a market value that offsets the global cost of biowaste valorisation.
To implement successful urban biowaste valorisation schemes to produce high value products with attractive and sustainable business cases, it is imperative to feed the processes with high quality biowaste in sufficient amount. This relies on efficient and successful biowaste selective collection systems which are scarce in Europe.
This deliverable gathers the main insights of the pilot biowaste selective collection experience carried out in Murcia (Spain) in the VALUEWASTE project. The experience was performed from the end of February 2020 to April 2022 targeting two main types of customers: citizens and large producers of biowaste. The collected biowaste was transported to Murcia’s waste pre-treatment plant where it was converted into proteins and biofertilizers following the VALUEWASTE project valorisation scheme.
The results obtained during the biowaste collection experience evidence that to achieve a successful biowaste collection, it is necessary to follow a specific process which is described in this report. We believe that this experience is useful in terms of replication by providing measures with recommendations and suggestions for the future implementation of biowaste valorising schemes. The process starts by deciding which day to launch the selective collection of biowaste in the selected area. Once that day has been chosen, there are a series of actions before and after that day.

The experience gained in this pilot experience will be used for the extension of the selective collection in the entire municipality of Murcia.
The actions proposed in this deliverable have been discussed and evaluated with other relevant stakeholders, resulting in the development of a CEN Workshop Agreement (“Key factors for the successful implementation of urban biowaste selective collection schemes1”), which is publicly available and can be found as an Annex to this document.
