Groups of companies often have similar needs for solutions to help them become more sustainable. Luxinnovation and its partners work on a range of sustainability-related innovation projects aimed at identifying potential future solutions. These pilot projects integrate companies in the same field of activity, value chain or geographical location.

Decentralised system of production, storage and auto-consumption of renewable energies: industrial zone

This pilot project explores the opportunities for implementing a decentralised system of production, storage and consumption of renewable energy in an industrial zone in order to meet the specific needs of the companies located there.

Catalogue of innovative solutions for craft manufacturing processes

This pilot project is aimed at evaluating the manufacturing processes and energy needs of specific crafts. The objective is to find innovative solutions to replace current fossil fuel energy needs, and to establish a catalogue of innovative solutions and best practices to help companies to become more sustainable.


The e-Holzhaff platform is a digital marketplace aimed at facilitating the connection between regional supply and demand in the wood sector. It is aimed at optimising the regional value chain and enhancing the sustainability of the sector.

Circular by Design Challenge

The Circular by Design Challenge offers Luxembourg and European companies and entrepreneurs the opportunity to develop their innovative, sustainable solutions through a 12-week coaching programme. Participants will be connected with an excellent network of partners looking to find sustainable solutions to thematic challenges and compete for a monetary award.

Deconstruction materials platform

In the context of the development of the circular economy in construction, buildings can be considered as product and material banks. Selective deconstruction is essential to recover materials and products likely to be reused by professionals (or individuals) on other building sites, and responds to the emerging demand of a reuse market.

Promoting recovered products and materials through virtual and physical platforms is a logical continuation of material inventories carried out on buildings to be deconstructed. The objective is to set up a virtual and physical platform in Luxembourg by 2023. The platform, which will be established together with the public and private partners concerned, could be inspired by similar platforms set up in Belgium, France and Germany.

Food supply chain

Since the pandemic, there has been an increased interest in implementing new forms of agriculture such as urban farming, vertical farming, and organic and local food production initiatives in Luxembourg. The idea is to create and grow a non-meat industry that produces, processes and markets food, largely in response to the daily demand of consumers within a neighbourhood often within a town, on many types of privately and publicly held land and water bodies found throughout intra-urban and peri-urban areas. The main objective for Luxembourg is to partially reduce our dependency on food import, consider the growing population living in Luxembourg and take into account the smart agritech approach in the country’s digital strategy.


 Aquaponics is a new food production sector based on the combined production of fish as well as fruit and vegetables relying on aquaponic technologies. A first company has been successfully set up, and the idea is to grow this sector and facilitate the installation of several units specialised in different fish species and crops. This model can then be sold to existing farmers who are interested in diversifying their activity or to other customers.

The objective of the project is to develop a fully closed greenhouse exceeding the current state of the art in terms of its closed loop approach and the different species offered. Once developed, this should make it possible to commercialise and offer standardised farms on the Luxembourg market.

Concrete recycling

The use of concrete in the construction industry in Luxembourg – which represents a minimum production of one million tonnes/year – implies the consumption of large volumes of raw materials which are still not recycled to any great extent: aggregates and sand (60% to 80%), concrete (7% to 15%), water (14% to 21%) and additives (5% to 10%). However, in the medium and long term, a shortage of aggregates is foreseeable, with a negative impact on concrete producers. Furthermore, cement manufacturing is a major emitter of CO2.

More systematic recycling of concrete could thus contribute to:

  • ease the pressure on primary raw materials, such as aggregates and sand, and use local secondary raw materials from deconstruction
  • achieve the climate objectives set by the PNEC (-55% of CO2 emissions by 2030 // 2005, climate objectives of the COP21 in Paris) and reduce the country’s carbon footprint
  • boost the sector, which is strongly present in Luxembourg.

Plastics recycling

The Luxembourg chemical recycling project aimed at fostering plastic transformers companies to look for technical solutions available to recycle multilayer and flexible packaging plastics. A business case has been established and this project should be transferred at the Greater Region scale to enable significant plastics wastes sourcing and also investments costs sharing. The recycling of plastic mixed is a key challenge for the future to reduce plastic waste and pollution.


Hydrogen and its various applications are expected to generate significant new business opportunities in the coming years and support the transition to a decarbonised society. The H2ORIZON project focuses on the identification of economic and R&D opportunities enabled by hydrogen technologies with the objective to set up Luxembourg-based hydrogen projects supporting the growth and decarbonisation of local companies.

The following benefits are expected:

  • set-up of public-private demonstration projects to showcase the economic and ecologic potential of hydrogen
  • development of a national hydrogen value chain having positive economic and ecologic impact (CO2 emissions reduction)
  • foster innovation and R&D projects in the field of hydrogen
