Informe COTEC: situación y evolución de la economía circular en España

La economía circular es una de las grandes transiciones en las que Cotec está inmersa y una de sus líneas prioritarias en las que está centrando sus esfuerzos. Con este tercer informe, Cotec quiere mantener su contribución al análisis de la situación de la economía circular en España y analizar las políticas puestas en marcha desde los distintos niveles administrativos. Esta entrega además incorpora un estudio detallado de las competencias y capacidades disponibles a nivel nacional para impulsar la transición circular, así como de las barreras y los elementos facilitadores para dicha transición. La economía circular ofrece una alternativa al actual modelo de producción, basado en una cadena de valor lineal que genera residuos en todas las etapas, desde la extracción de materias primas hasta la generación de residuos, pasando por las fases de fabricación, distribución y consumo. La alternativa consiste en prolongar la vida económica útil de los materiales y los recursos tanto como sea posible, reduciendo al mínimo la generación de residuos.
Tercera entrega de este informe bienal analiza la evolución y la situación actual de la economía circular en España respecto a Europa.

REVALPET: Life cycle assessment
Santana Pérez, Orlando Onofre
The present report is part of the Interreg POCTEFA project RevalPET, which goal is to find new outputs for the recycling of opaque polyethylene terephthalate (PET) bottles.
This report is focused on the Life Cycle Assessment (LCA) part of the project, and describes the methodology employed as well as the results obtained. Therefore, the details of the procedure are presented in Section 2. The environmental impacts analysed are Abiotic Depletion (fossil), Global Warming, Eutrophication and Acidification. Section details the inventory of data used for the LCA. Section 4 shows the results, and Section 5 concludes this report.

RevalPET: Scaling up of the processing conditions (extrusion blending) of the optimized formulation
Santana Pérez, Orlando Onofre
This deliverable describes the procedure and main results of the scaling up process processing as well as the conditions of blends compounding at pre-industrial scale.
The action was carried out in three phases: 1) homogenization of rPET-O flakes, 2) Preparation of blends at pilot plant scale and 3) Evaluation of the quality of the product. The latter was carried out on extruded sheets under typical PP processing conditions, in order to establish the potential characteristics that a product would present, both morphologically and mechanically.

Development of high-performance materials based on opaque PET packaging: Mechanical properties of recycled polymer blends: tensile tests, fatigue test, impact tests
Santana Pérez, Orlando Onofre
This report focuses on the mechanical characterization of blends prepared adding 10%, 20% and 30% w/w of rPET-O, and the evaluation of the effect of additional amount of TiO2 added to the blend with 20% w/w of rPET-O. The blends were subjected to two different kind of processing: Injection moulding and extrusion-calendering.

Development of high performance materials based on opaque PET packaging: Preparation of samples by melt extrusion
Santana Pérez, Orlando Onofre
The first step of this work is the preparation of blends by melt extrusion. The objective of this deliverable is to describe the processing conditions of these blends. We do not deal with the characterization of blends properties here: it will be the subject of two other deliverables.
The most important points of this deliverables are as follows:
- The UPV/EHU team processed blends of virgin polymers, in order to compare their properties with those of blends of recycled polymers. Blends were stabilized with both conventional stabilizers (PE-g-MA for blends containing PE and PP-g-MA for blends containing PP) and TiO2 nanoparticles, in order to compare both stabilization techniques. Blends were processed in a Collins ZK 25T co-rotative twin-screw extruder. For rheological and morphological characterization, samples were processed by compression in the molten state.
- The UPPA team worked on blends of recycled polymers. Processing was performed in a LABTECH engineering company Ltd co-rotative twin-screw extruder with L/D=40. For rheological characterization, samples were processed by compression in the molten state.
- The UPC team evaluated the degradation of opaque PET during extrusion, and compared it with the degradation of recycled, transparent PET in different conditions. The conclusion is that the degradation of opaque PET is comparable to that of transparent PET in the same extrusion conditions, and that the decrease in intrinsic viscosity (2%) is acceptable in the PET industry.
