The Keiryo PET solution has been awarded the ‘Solar Impulse Efficient Solution’ label, a proof of high standards in profitability and sustainability


Keiryo Packaging Technology’s PET Solution modifies the morphological structure and performance of polymers during the injection process. It is a 3D printed metal insert retrofitted into existing Injection Stretch Blow Molding (ISBM) machinery and allows to reduce the environmental footprint and manufacturing cost of PET bottles.
The Solar Impulse Efficient Solution’ label was awarded following an assessment based on verified standards. It is thereby joining the #1000 solution challenge, an initiative by the Solar Impulse Foundation to select solutions that meet high standards in profitability and sustainability and present them to decision makers to fast-track their implementation.

To receive the “Solar Impulse Efficient Solution” Label, the Keiryo PET Solution was thoroughly assessed by a pool of independent experts according to 5 criteria covering the three main topics of Feasibility, Environmental and Profitability. All labelled solutions are part of the #1000solutions portfolio that will be presented to decision-makers in business and government by Bertrand Piccard, Chairman of the Solar Impulse Foundation. The aim of this initiative is to encourage the adoption of more ambitious environmental targets and fast-track the implementation of these solutions on a large scale.

The Keiryo PET solution demonstrates that increased sustainability does not have to come with trade-offs in terms of cost and functionality. It is a cost saver, is easy scale whilst reducing the environmental footprint of PET packaging. This was recognized by the Solar Impulse Foundation and we are proud to be part of the #1000 solutions challenge” says Johan Robbrecht, Managing Partner of Keiryo Packaging Technologies.


Keiryo Packaging Technologies is developing a patented polymer processing technology which introduces well-designed mechanical energy into the polymer melt during its processing. Consequently, the molecular organization of the polymer melt is altered with the creation of flow-enhanced morphological structures which have a beneficial impact on the end performances of the polymer article being produced.  This enables light weighting, better barrier performance and improved mixing of virgin and recycled material. In doing so the Keiryo Packaging Technology improves the environmental sustainability of polymer-based packaging.
Keiryo Packaging Technologies is incorporated in Luxemburg and headquartered at 488 route de Longwy, Luxemburg.

About the “Solar Impulse Efficient Solution” Label

One of the first labels for positive impact businesses bringing together protection of the environment and financial viability, the “Solar Impulse Efficient Solution” Label is attributed following an assessment performed by external independent experts. In collaboration with renowned institutions, solutions applying for the label must go through a neutral methodology based on verified standards. This label serves as an award for clean and profitable solutions.

About the Solar Impulse Foundation

The Solar Impulse Foundation is dedicated to accelerating the implementation of clean and profitable solutions. Moreover, the Foundation is helping decision-makers in businesses and governments to achieve their environmental targets and adopt more ambitious energy policies, which are necessary to pull these solutions to market. A way to carry the success of the first solar-powered flight around the world further.
