Objectives

The REDOL Project drives technological, managerial, economic, and social readiness in European circularity hubs. Experience innovative and sustainable approaches to valorize solid urban waste (SUW) through industrial-urban symbiosis (I-US). Discover the transformative impact of the REDOL Project and the social readiness level of European Hubs for circularity.

To this end, five different value chains for packaging, plastics, construction demolition waste (CDW), textiles and waste electric and electronic equipment (WEEE) will be developed and implemented in real waste management facilities, obtaining recycled secondary materials for the latter production of high added value circular products.

REDOL goals

Advance technological, managerial, economic and social readiness level of European Hubs for circularity.
The specific goals that will enable the achievement of REDOL Project main objective include:

1

To develop and demonstrate novel management systems and processing technologies for the valorisation of SUW to be used as feedstock for other sectors and/or across value chains.

2

To obtain recycled secondary materials from SUW ready to be fed in downstream processes
for the further production of circular products, closing the production loop.

3

To enable the achievement of a zero SUW landfilling approach in Zaragoza by accomplishing 55-100% recycling rates in REDOL value chains while creating new sustainable economic across Aragon.

4

To establish a roadmap for the implementation of REDOL solutions in other urban environments and industrial areas, tackling technical and non-technical barriers.

5

To assure a successful dissemination and exploitation of the project, through a strategic and I-US oriented commercialization plan, dedicated business models and key stakeholders’ engagement.

Impact

REDOL Project will directly impact in the transition of Zaragoza towards a zero residues city, aiming at achieving this objective by 2040.

Taking into account that the current recycling rate is around 50%, this would imply over 140,000 tons/year being re-used, valorised or transformed into secondary raw materials instead of landfilled.

Such an approach will result in a total of 144.720 tons/year being re-used, valorised or transformed into secondary raw materials instead of landfilled (over 90.000 tons in the value chains addressed in the REDOL Project).

It must be considered that potential increments in the number of residues generated within the city would further increase this impact, as residues generation is currently increasing by 2% per year, but efforts are placed in achieving a reduction in these figures.

Accordingly, REDOL innovations at technical, economical, managerial and social level will enable the consolidation of Zaragoza’s hub for circularity and leverage benefits within the city of over 14 B€ and 280 ktCO2/year, economic and GHG emissions savings respectively.

Value chains

In particular, the impact of REDOL Project on the value chains addressed is expected to reach the following figures:

The overall packaging recycling rate by the end of the project is expected to be up to 70%, which represents landfilling savings of over 24 ktons when compared to current benchmark (44% recycling rate for almost 100 ktons of waste packaging in Zaragoza).

Due to the currently low recycling rate on plastics (20%), the objective has been set in 55%, thus resulting in up to 22 ktons of plastics being recycled.

In addition, the objective is to maximise synergies with on-going initiatives such as PLASTICE, whose reactors for depolymerization will be linked to REDOL to reach near zero plastic waste in overall.

REDOL will make possible to classify and recycle mixed waste at CAS facilities, which represents about 50% of the total managed residues, 40.000 tons.

The valorisations routes proposed within REDOL will transform 80% of these residues, i.e., 32 ktons, into valuable construction and cement secondary raw materials and products.

Only 14% is of textile waste produced in Zaragoza is currently recycled based on separated collection procedures.

The implementation of REDOL approach after its demonstration in Prato is aimed at classifying and recycling the most challenges textiles, such as those including elastane or mixed fibres of PET and cotton, thus making possible the full recycling of the 12 ktons textile waste of the city.

Currently waste electric and electronic equipment (WEEE) counts as 100% recycled waste due to the specific collection and management processes.

However, costs related to manual sorting procedures and valorisation processes prevent the reintroduction in the market of their many valuable materials.

REDOL will tackle both barriers to enable the circularity of the whole 315 tons of WEEE managed by TAT per year.
