Eco-friendly bio-based insulation materials for energy-efficient building renovations

constructionTestedTRL 5

Imagine replacing old, chemical-heavy wall insulation with materials made from sea grass or plant-based foams. It's like giving a building a natural warm coat that keeps heat in and pollutants out. This makes homes cheaper to heat and much kinder to the planet.

The business problem

What needed solving

Traditional building insulation relies on fossil resources and high-emission manufacturing, while the EU faces a shortage of materials to meet strict energy renovation targets.

The solution

What was built

Developed bio-based Posidonia panels, flame-retardant coatings, PLA foams, sprayable insulation, and bio-based window frames.

Who can put this to work

Construction & Renovation
SME
Target: Residential renovation contractor

If you are a contractor dealing with high carbon footprints in old buildings — this project developed prefab bio-based panels and sprayable insulation that reduce energy demand and CO2 emissions. These solutions aim for a 7-year payback period for the end user.

Building Materials Manufacturing
mid-size
Target: Insulation product manufacturer

If you are a manufacturer dealing with the shortage of traditional insulation materials — this project developed Posidonia panels and PLA foams. These serve as non-hazardous alternatives to fossil-resource components at a comparable price point.

Real Estate Development
enterprise
Target: Green building developer

If you are a developer dealing with strict EU energy directives and ESG requirements — this project developed smart bio-based components for windows and walls. This helps increase the market share of sustainable residential buildings while lowering VOC emissions.

Frequently asked

Quick answers

What is the expected cost and return on investment?

The project aims to position bio-based materials at a comparable price value to fossil-resource components, targeting a 7-year payback period for the solutions.

Can these materials be produced at an industrial scale?

The project focuses on boosting the use of available bio-based materials to close the insulation shortage gap and is developing prefab panels and sprayable solutions for marketability.

How is the intellectual property or licensing handled?

Based on available project data, specific licensing terms are not mentioned, but the project involves 14 industry partners and 12 SMEs developing marketable smart components.

Do these materials comply with EU building regulations?

Yes, the project specifically maps certification needs and aligns with the Energy Performance of Buildings Directive and the Energy Efficiency Directive.

What is the timeline for implementation?

The project runs from 2023-01-01 to 2026-12-31, with the first 18 months already spent on technical set-up and material development.

Consortium

Who built it

The consortium is heavily industry-driven, with 14 industrial partners representing 74% of the group. The strong presence of 12 SMEs across 11 countries suggests a high focus on commercial viability and rapid market entry rather than pure academic research, supported by only one university.
