Naples, Italy – October 2–3, 2025

The R-PETFOAM Project, led by CIDAUT, you have entered a major new development phase. Our research team has successfully produced the first prototypes of structural foams made entirely from 100% post-consumer, mixed-color recycled PET (rPET) — a milestone that demonstrates the technical feasibility of circular, high-value materials derived from real waste streams.

Thesis preliminary results were presented at the FOAMS® 2025 Conference, organizedby SPE's Thermoplastic Materials & Foams Division, in the sunny city of Naples, Italy. The event gathered world-leading experts in polymer foaming to exchange knowledge on micro- and nanocellular structures, novel foaming agents, bio-based materialsand sustainable processing innovations.

We extend our thanks 🙌 to the organizers and participants of FOAMS® 2025 for providing an inspiring forum that continues to push the frontiers of polymer foaming technology.

New Foaming Infrastructure at CIDAUT

We are proud to announce that as of 2025, CIDAUT operates a unique extrusion foaming line dedicated to the continuous production of cellular thermoplastics, with a capacity of 10–15 kg/h.
This new capability is the result of several months of intensive interdisciplinary work, including:

  • System design and installation: custom machine building, electrical modifications, and integration of an extruder extension, twin-screw configuration, advanced melt filtration, CO₂ injection, and a dedicated foaming die.
  • Material development: optimization of raw material blends, intrinsic viscosity, melt strength, nucleation behavior, and compatibilization for mixed rPET streams.
  • Process optimization: fine-tuning of CO₂ content, temperature profiles, pressure-drop rate, and shaping parameters to achieve stable, uniform foam structures.

These developments significantly expand CIDAUT's R&D capacity to explore supercritical CO₂ foaming, recycled polymer circularityand energy-efficient lightweight materials — key enablers for Europe's transition toward a more resilient and competitive industrial ecosystem. 🇪🇺🧪🌍

CIDAUT and the R-PETFOAM projects remain dedicated to advancing science-based circular materials, turning innovative foaming research into industrial solutions that combines performance, sustainability, and European competitiveness.

Supplier policy

Guidelines for the evaluation, selection, performance monitoring and re-evaluation of external suppliers of the CIDAUT Foundation

1. Object

This document is established to inform CIDAUT Foundation suppliers of the general guidelines followed for the evaluation, selection, performance monitoring and re-evaluation of external suppliers.

2 Area of ​​application

In accordance with the requirements of ISO 9001:2015, this document applies to external suppliers of the CIDAUT Foundation that supply products and services that may adversely affect the ability to deliver the results of the projects, technological services and tests that develops the CIDAUT Foundation. Below is a non-exhaustive list of processes, products and services to which these guidelines would apply:

Services and/or processes of:

  • tests, proficiency tests, calibrations or sampling
  • design
  • manufacturing of parts, molds, tools, electrical and/or electronic components, elements or assemblies necessary for the manufacture of prototypes, machines or any element that will be delivered to the client or on which tests or tests will be carried out that will constitute the results to deliver to the customer
  • analysis, evaluation, audit or technical advice whose conclusions and/or results will be integrated into the results to be delivered to the client
  • development of specific facilities for the development of projects, technological services or trials
  • key support services that can affect the outcome of projects, technological services or tests: maintenance of facilities and equipment, software administration and maintenance, etc.

Products

  • standards and auxiliary equipment for calibration/verification of measurement and monitoring equipment
  • reference elements and materials
  • measurement and monitoring equipment
  • raw materials that must meet specific requirements of the Project, Technological Service or Test
  • materials, reagents, additives, etc. necessary for the development of a new material that will be the result of the technological project or service or on which the tests or tests that will constitute the outputs/results of the technological project or service will be carried out.
  • consumables that must meet specific requirements for the correct operation of key equipment / installation for the development of the project, technological service or test
  • key equipment and facilities for the development of the project, technological service or test
  • software that can determine the results of the project, technological service or test (CAD/CAE/CAM)

3. Development
3.1. Evaluation and selection of suppliers
The Foundation Purchasing Manager establishes the criteria based on which the evaluation and selection is carried out in order to guarantee that the selected supplier supplies the products and services in accordance with the necessary requirements. The selection criteria are a combination of the following depending on the type of product/service:

  • Ability to meet legal requirements and customer requirements
  • Adaptation to the specific need: For complex products/services, the proposal of the supplier that best meets the need
  • Technical Capacity: The supplier has the appropriate material and human resources
  • ENAC accreditations: The supplier is accredited by ENAC for the development of calibrations, tests, etc.
  • Certifications: The supplier has a current ISO 9001 certification and within its scope are the products and/or services that are the object of the need.
  • Provider recommended or established by the Client
  • Previous experience: Provider in other departments or projects
  • Market recognition
  • References from clients, competitors, etc.
  • Risk and guarantees: Level of risk assumed by the supplier and/or guarantees offered
  • Financial Capacity: For large purchases
  • Supply Capacity
  • Flexibility towards changes
  • Accessibility
  • Ability to meet deadlines
  • Price
  • Payment method
In addition to the established criteria, whenever possible, for purchases exceeding the amount of 3.000? The selection of the supplier will be carried out by requesting offers from at least 3 suppliers.

3.2. Monitoring performance and reevaluation of suppliers.
To ensure that controlled external suppliers continue to supply in accordance with established requirements, suppliers are subject to periodic monitoring and control. Depending on the type of provider, it is established:

Supplier type Tracking Re-evaluation
Regular: regular suppliers X X
About project: specific suppliers for a given project X Does not apply
Occasional: single purchase suppliers Does not apply Does not apply

Tracking
Monitoring of external suppliers is carried out continuously:

  • Checking the maintenance of the ISO 9001 certification or ENAC accreditation that served as the basis for the approval. In case of loss, approval could be withdrawn.
  • Checking compliance with commercial agreements
  • Review of the quality of purchases made.
    • Anomalies attributable to the supplier are tracked. When an incident gives rise to a customer claim or significantly affects the outputs or results of the project, technological service or test, a Non-conformity is opened. When the supplier's response is not adequate or when the severity of the anomaly causes the CIDAUT Foundation to lose confidence in the supplier, the approval is withdrawn.
Continuous monitoring also takes into account response times and price developments. When necessary, the Purchasing Manager may define other monitoring activities. Some possible follow-ups are:
  • Audits
  • Service quality reviews
  • Visits to the supplier
  • Product inspections
  • Monitoring of indicators
  • Meetings with service users

Re-evaluation
Regular suppliers are periodically re-evaluated. For this, it is reviewed:

  • the criteria by which they were initially approved
  • the maintenance of ISO 9001 certification or ENAC accreditation if they were determining elements in the approval of the supplier
  • compliance with trade agreements
  • the history of incidents and follow-ups carried out
  • the level of service of the provider taking into account in particular unanswered requests, response times and accessibility
  • price variations and its comparison with other competitors
