Objective. Development of new solutions for the efficient reuse of industrial plastic waste
The ADITECH project emerges as a continuation of the ADITIV project, with the aim of continuing the valorization of industrial plastic waste through its transformation into new materials suitable for additive manufacturing, thereby promoting their reintroduction into the value chain under a circular economy approach.
The main objective of ADITECH is to develop new technological solutions that enable the efficient reuse of plastic waste from the industrial sector, especially in the automotive field by adapting it to 3D printing processes.
To achieve this, the project addresses both the improvement of recycled material properties and the development of advanced control and classification tools, integrating technologies such as hyperspectral imaging and computer vision.
The project is developed within the framework of the 2025 Innovative Business Groups (AEI) call, funded by the Ministry of Industry, Trade and Tourism, and led by CAAR, with the participation of ASAI, ATRIA Innovation, R3DIMENSION and CEAGA.
Project development
The project is structured into different work packages aimed at covering the entire value chain of recycled materials:
-
Analysis and characterization of plastic waste from industry, identifying materials with the highest reuse potential.
-
Research into new formulations, incorporating additives and studying blends of recycled materials to improve performance.
-
Application of hyperspectral technologies for advanced identification and separation of waste.
-
Development of computer vision systems for defect detection and quality control in manufactured parts.
-
Definition and execution of physical tests to compare the performance of recycled materials with virgin raw materials.
-
Study of the lifespan of new materials in real applications

Current status
The project is currently in the development phase, with activities from work packages WP1, WP2, and WP3 already completed, including:
-
State-of-the-art study and bibliographic analysis.
-
Identification of main industrial plastic waste streams.
-
Initial data capture and analysis using hyperspectral technology.
-
Early development of formulations with recycled materials and additives.
-
Definition of physical tests for property validation.
-
Initial progress in computer vision systems for quality control.
These results provide a solid foundation for the validation of materials and technologies in later stages of the project.
Technology Readiness Level (TRL)
The project starts from an approximate TRL of 3–4, focused on the experimental validation of concepts and technologies in a laboratory environment, and aims to reach TRL 5–6 through validation in relevant environments and closer alignment with real industrial conditions.
Impact
ADITECH will:
-
Promote the reuse of plastic waste in industrial sectors.
-
Reduce the environmental impact associated with these materials.
-
Improve the viability of additive manufacturing using recycled materials.
-
Incorporate advanced control and classification technologies into industrial processes.
-
Foster circular economy models in the automotive sector.
