The need to limit the use of fossil resources and develop multi-criteria indicators to assess the transition to new bio-based sectors in the context of climate change is now a pressing issue in our societies.

Created from the merger of the Transformations & Agroressources and CYCLANN units, the ÉCLORE unit has several objectives:

  • To offer new functionalized bioproducts (ranging from molecules to materials and bioenergy) obtained from various types of biomass (co-products, by-products)
  • To optimize co-valorization
  • To develop systemic assessment tools using these case studies as examples.

The challenges facing the ÉCLORE unit

The challenges facing the unit are to characterize the properties of biomass and co-products of agricultural and marine origin, as well as organic urban and peri-urban waste, and to analyze and understand their transformation into bio-based products in order to promote the circular economy.

These challenges are addressed through the design of regional circular economy systems (regional flows) and co-valorization in order to transition towards the efficient and complementary use of renewable materials through a systemic assessment approach, while combining biotechnical and environmental approaches.

ÉCLORE's scientific project

Thematic area no. 1 - "Characterization and functionalization of biomass for the construction of eco-designed bio-based materials "

This theme aims to select, characterize, process, and transform secondary plant raw materials, mainly lignocellulosic, by combining new co-products, such as cellulose hydrogels, in order to meet the multi-criteria functionalities and properties (physical, mechanical, chemical, thermal, biological, dielectric, piezoelectric) and multi-scale functionalities and properties of eco-designed bio-based materials.

Thematic area 2 – “Deconstruction and material/energy recovery from biomass and effluents.”

This theme aims to treat urban and agro-industrial effluents, in particular through a material/energy recovery and reuse approach, but also to promote the energy recovery of renewable resources and waste. This is achieved through solid and liquid methanisation, and through bioprocess-type fermentation activities for the environment aimed at producing energy carriers, biofuels and platform molecules.

Current projects

Budget: €4 million, of which €2.4 million is funded by the European Union - INTERREG North West Europe

Objective:

Every year, 37 million tons of residual biomass are underutilized in North-West Europe (NWE), which corresponds to a potential of 30 million tons of CO2 emissions avoided, or 2.5% of NWE's CO2 emissions. Previous projects have shown that much of this biomass can be recovered and valorized to replace peat or fossil coal and create value chains with a negative carbon footprint. However, comprehensive approaches to biomass management are lacking for implementation in these regions.

This project will fill this gap by introducing circular biomass management systems in seven pilot regions via biomass valorization pathways into biochar and will create seven application scenarios that can be transferred to other regions.

As part of a transnational collaboration, a partnership of public entities, scientific institutes, and private/non-governmental R&D organizations will work on the circular design and valorization pathways for biomass:

In the first phase, biomass valorization pathways will be introduced, managed, and optimized, taking into account input variability, collection optimization, and transformation and conversion in the pilot regions at the urban and rural scales.

In a second step, regional pilot projects will be quality-checked and improved throughout a Plan-Do-Check-Act process based on technological, ecological, economic, and social criteria.

In a third step, a capacity-building program will be designed and implemented to deploy bio-based transformation pathways in these regions. A center of excellence and TechLab CASCADE will guarantee quality and offer training and development activities, roadshows, and a hybrid exhibition on bio-based products, services, and systems

Expected results:

  • Successful implementation of carbon management systems in seven pilot regions, which will serve as a model for other European regions.
  • Reduction of CO2 emissions through the creation of circular and CO2-neutral biomass-to-biochar transformation processes.
  • Establishment of a capacity-building program, a center of excellence, and a TechLab to support ongoing training, development, and dissemination of project methodologies.
  • Development of transferable application scenarios to facilitate the large-scale deployment of these systems across Europe.

Karine Dufosse, Marine MARIE-CHARLOTTE, Vincent Augiseau, Thierry Henrion and Hayet DJELAL (2022) co-authored this article: Quantification and environmental assessment of wood ash from biomass power plants: a case study from the Brittany region in France, Sustainability

The BIMGC project is part of a wider initiative to promote the use of fly ash, a by-product of biomass heating systems. The construction industry has been selected for this project, which involves adding fly ash to concrete and/or using it as a substitute for cement. This study was made possible by a consortium comprising:

*Laboratoire de Génie Civil et géoEnvironnement - LGCgE,

* L'IUT de Béthune (62),

* The Cyclann research platform at UniLaSalle Rennes,

* the Materials Science Department of the Faculté Polytechnique de Mons - UMONS (Belgium),

* the CERIB (Centre for Studies and Research in the Concrete Industry) (28),

* Biallais Industries (62), a manufacturer of concrete blocks, and

* Dalkia Aegis, EDF Group Bois Energie Nord-Ouest (59).

 

The study is continuing with the BIOGRAFIC project (Valorisation of biomass ash as aggregates and fillers in construction blocks) with the same consortium and still supported by ADEME, ADEME Graine Project (2021-2023).


 

Completed projects

Objective:

The main challenge of the European Interreg ThreeC project is to promote the development of bio-based charcoal production chains in a sustainable manner that respects climate issues.

In France, one of ThreeC's challenges is to identify, bring together, and then form groups of stakeholders interested in biochar (bio-based charcoal) at all levels of the sector:

  • biomass producers
  • processors (e.g., gasification stakeholders)
  • users of charcoal for water and air treatment and agricultural uses

This project aims to develop and introduce economically viable value chains based on the use of biochar from biomass waste in northwestern Europe.

Project leader: University of Kassel, Germany

The ThreeC project has a budget of €5.62 million over four years (2019-2023), co-financed by the ERDF (European Regional Development Fund) to the tune of €3.37 million.

ThreeC Project News

Two types of biochar produced from flax shives and beech wood residues were evaluated for their adsorption capacity with methylene blue (MB). A series of adsorption tests with carbamazepine (CMZ) was also carried out. Post-treatment of the biochars with citric acid (CA) or surface oxidation by heating at 250°C under atmospheric conditions was carried out to modify the surface functionality of the materials. The oxidized biochars showed a high specific surface area compared to the untreated biochars. The Langmuir model showed the best fit to the MB and CMZ isothermal adsorption data. The effect of pH, adsorbent doses, and initial MB and CMZ concentrations on adsorption efficiency was also discussed.

Designing Bio-based and biodegradable Packaging through Agriculture Waste Valorization .

Objective

The project focuses on exploring locally available agro-resources such as starch, flax, etc., for the design of bio-based and biodegradable packaging.

Partners

National Institute of Food Science and Technology, University of Agriculture Faisalabad, Pakistan.

Contact: Aamir SHEHZAD

Objective

Develop recyclable and/or compostable barrier packaging to replace current multi-layer films, which are incinerated (44%) or landfilled (56%).

This project is funded by the European Union and the Normandy Region.

Challenges

The multi-layer film market accounts for 50% of the global flexible packaging market, which alone generates 10MT of waste per year in Europe, or 36% of plastic waste.

Fossil-based multilayer solutions meet the requirements of packaging applications, but their complex structure (assembly of different layers of polymers) makes them non-recyclable, while bio-based solutions do not currently offer all the properties required, such as barrier properties, mechanical characteristics, transparency, bacterial safety, and sealability.

The main challenge of the project is to overcome these obstacles while maintaining recyclability and/or compostability in line with the circular economy. From an economic point of view, REACT aims to establish a sector in the Normandy region for the design, production, and recovery of recyclable and/or compostable barrier plastic packaging.
