Circular economy · New materials for construction
We give new purpose to plastic waste (including PET, PE and other polymers), composites and construction and demolition waste, developing circular solutions for construction.
Initial scope: Portugal and Spain
Illustrative industrial image · Does not depict OMNI MATTERIA facilities
Value proposition
OMNI MATTERIA works on two complementary fronts: recovering waste with technical potential, and developing new materials for the construction sector.
We identify waste streams with recovery potential together with companies, public bodies and waste operators.
We assess composition, quality, volume, regularity and logistics conditions of every stream submitted.
We develop new construction applications from recovered materials, in a prototyping and testing environment.
We create value from materials that have lost their original use, keeping them in productive use.
The positioning is industrial and technical: every stream is analysed case by case and no application is assumed before validation.
Feedstock sought
We look for regular or one-off streams of materials with technical potential. All materials are subject to prior characterisation and technical assessment.

First solution under development
A product currently under development and prototyping, made of recycled plastic and other composites, with a concrete outer layer.
The solution is being designed for use in retaining walls and as a future alternative to gabions.
Characteristics, performance and availability are subject to prototyping, testing and technical validation.

OMNI MATTERIA intends to apply the same waste recovery principle to the development of prefabricated panels.
These panels are intended, among other uses, for the walls of factories and industrial buildings. This is a research track: companies and specifiers can register interest in these solutions or propose other applications they consider relevant.

Collection of plastics, composites and construction and demolition waste.
Sorting and analysis of material composition and homogeneity.
Formulation and laboratory testing under way.
Circular solutions for construction, under development.
Work sequence. It does not represent installed capacity or tested results.
Defining the concept, formulations and material recovery criteria.
Producing prototypes to assess how the materials behave.
Testing and technical validation of characteristics and performance.
Future availability, depending on the results of the previous stages.
The project is under development and prototyping. The following stages are not complete.
Circular economy
The OMNI MATTERIA approach starts from a simple principle: materials that have lost their original use can retain technical value when properly characterised and reapplied.
Extending the usefulness of materials, keeping them in productive use for longer.
Reducing the disposal of waste that today goes to final destination.
Incorporating recovered materials into new construction applications.
Developing solutions geared towards greater circularity in the construction sector.
We do not publish environmental impact figures: any such value requires validated measurements and life-cycle analysis.
Main form
Submit the material for technical assessment. The more complete the information, the faster the analysis.
Secondary form
For future buyers and specifiers who wish to follow the development of these solutions.
