One of Cyclann's scientific objectives is to contribute to limiting the impacts and nuisances of waste and its management. The research unit also actively participates in the implementation of circular economy approaches and policies at the territorial level in order to allow the integration of the principles of the societal responsibility of organizations (RSO) and to meet the objectives of sustainable development (ODD).
The scientific project
The Cyclann team is particularly interested in four topics:
- engineering and environmental sciences
- water and effluent quality
- effluent and waste treatment
- environmental assessment
The research areas are mainly related to engineering and environmental sciences:
- Water and effluent quality: characterization of organic matter (natural, anthropogenic, particulate, colloidal pollution), indicators, degradation factors...
- Effluent and waste treatment and biological recovery: development and optimization of physico-chemical, electrochemical and biological processes: biostimulation, bioacclimatization, bioethanol production, methane production, platform molecules
- Environmental assessments: development of environmental performance assessment methodologies: integration of LCA software, methodological aspects related to eco-design
- Diagnosis and prospective on the flow of building materials and construction waste; analysis of material flows and stocks (metabolism) for the implementation of circular economy policies or approaches
The team works on this theme in association with the LERES (EHESP). The aim is to study the quality of water and effluents in order to understand phenomena such as the change in water quality in a context of climate change.
The objective is to develop, optimize and control treatment processes (organic matter/anthropic matter discrimination) by characterizing the phenomena of pollution transfer between the different granulometric fractions. The team is therefore working on defining indicators, degradation factors or contributing to the development of monitoring methods based on optical methods.
The team works particularly on :
- treatment by bioaugmentation or biostimulation on industrial or synthetic effluents ;
- electrochemical treatment of effluents containing metals and nanoparticles;
- the treatment of gaseous effluents by absorption.
Some works, in particular the treatment of gaseous effluents containing VOCs by absorption, are carried out in collaboration with the ENSCR research laboratory. In the field of biological treatments, the projects aim to develop and optimize treatment processes.
Projects in this area aim to implement environmental assessment methods such as life cycle assessment or to propose methodologies to evaluate, for example, the environmental impact of a new treatment process.

Lise SWERTVAEGER est diplômée Ingénieur Génie de l'environnement de l'EME.
Elle a fait son stage de fin d’études chez Suez (Ex CITA) et a signé son 1er emploi à la suite en tant que Responsable d’exploitation sur les métiers de collecte.
Ses clients étaient des collectivités territoriales du Finistère. Elle a encadré une équipe d’une vingtaine de personnes pendant 4 ans.
Ensuite Lise a été responsable d’exploitation de la collecte du centre-ville de Rennes. Elle manageait alors une équipe de 65 personnes, ouvriers et techniciens pendant 3 ans.
Elle a évolué sur le management de 2 exploitations Cesson Sévigné et Chartres de Bretagne (Responsable de contrats). Son client principal restait Rennes Métropole.
Elle a encadré 120 personnes : du manager d’équipes aux cadres d’exploitation. Elle veillait au respect des normes et de la réglementation, élaboration et respect du budget et satisfaction du client.
Pour découvrir d’autres modes de fonctionnement et s’ouvrir, Lise a intégré le groupe Sturneau, le pôle déchet, une PME en tant que responsable d’activité. Elle a élargi son champ de compétences : elle avait une dizaine d’exploitations sur la gestion des déchets réparties sur la Bretagne et la Normandie. Management à distance, développement commercial. Ce qui lui plaisait était la diversité des clients et des activités : collecte, traitement et valorisation des déchets. Lors du confinement et pour répondre au besoins des clients, Lise et ses équipes ne se sont jamais arrêtées !

Margaux LHUISSIER (Bourse CIFRE entreprise CHIMIREC, Co-encadrement : A. KANE, UniLaSalle Rennes - A. AMRANE Université Rennes1- J-L. AUDIC, Université Rennes1, Directrice de thèse : A COUVERT, ENSCR) – projet ECOV (2016-2019)
Ce projet propose la réutilisation d’huiles collectées par une entreprise de collecte et de recyclage d’huiles usagées. L’objectif étant de capter les COV émis sur leur site, tout en prévoyant leur valorisation concomitante.
Le but étant de transformer ce qui était jusqu’ici considéré comme un déchet en une ressource valorisable sur site et à moindre coût. Le projet ECOV s’inscrit dans un contexte de lutte contre la pollution atmosphérique et en particulier dans la limitation des rejets de COV et des molécules odorantes.
En plus des enjeux environnementaux, le projet présente des enjeux économiques liés à une baisse de l’investissement dans le procédé et une diminution du coût de fonctionnement grâce à une régénération de l’absorbant, rejoignant ainsi les grandes préoccupations du développement durable.
Alaa SALMA (Direction H. Djelal, co-encadrement A. Amrane UR1, Florence Fourcade UR1, en partenariat avec l’ENSCR) - bioproduction de molécules plateformes par fermentation et électrofermentation (2017-2020)
La valorisation de matières premières secondaires par fermentation s’accompagne de nombreux métabolites qui peuvent être valorisés en énergie (éthanol, H2, CH4) mais aussi en matière (glycérol, acide succinique …). Le procédé de fermentation à partir de biomasse permet la production de composés organiques qui seront impliqués dans d’autres procédés industriels. Ces molécules « plateformes» sont souvent des molécules bioactives à usage thérapeutique, cosmétique ou alimentaire.
C’est dans ce cadre, qu’une enseignante chercheure (H. Djelal, 30 %) participe à l’Appel A Projet : Action Incitative "Défis Scientifiques Émergents 2018" sur la “Production de bioethanol et de molécules plateformes par voie fermentaire-séparation et récupération du produit d’intérêt” (2018-2019). Le porteur du projet est l’UMR CNRS 6226 – ISCRennes. Ce projet consiste à valoriser des co-produits de l’industrie agro-alimentaire en éthanol et en molécules plateformes par voie fermentaire. Afin de séparer et de récupérer les molécules d’intérêt une étape de séparation est nécessaire. Différents procédés de séparation membranaires sont envisagés seuls ou en cascades comme la microfiltration ou la distillation membranaire.
Research Projects
Budget: 4M EUROS of which 2.4M financed by the European Union - INTERREG North West Europe
Objective:
Each year, 37 Mio t of residual biomass is under-utilized in North West Europe (NWE), which corresponds to a potential of 30 Mio t of avoided CO2 emissions, i.e. 2.5% of NWE's CO2 emissions. Previous projects have shown that a large proportion of this biomass can be recovered and valorized to substitute peat or fossil coal and create value-added pathways 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 7 pilot regions via biochar biomass recovery pathways, and will create 7 transferable application scenarios for 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 circular design and biomass valorization pathways:
In the first phase, biomass recovery pathways will be introduced, managed and optimized, taking into account input variability, optimized collection, transformation and conversion in pilot regions at urban and rural scales.
In the second stage, regional pilot projects will be quality-controlled and improved through a Plan-Do-Check-Act procedure based on technological, ecological, economic and social criteria.
In the third stage, a capacity-building program will be designed and implemented to deploy bio-based processing routes in these regions. A CASCADE Center of Excellence and TechLab will guarantee quality and offer training as well as development activities, roadshows and a hybrid exhibition of 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, CO2-neutral biomass-to-biochar processes.
- Establishment of a capacity-building program and a Center of Excellence and TechLab to support further training, development and dissemination of project methodologies.
- Development of transferable application scenarios to facilitate large-scale deployment of these systems across Europe.

- biomass producers
- processors (e.g. gasification operators)
- coal users for water and air treatment and agronomic uses.
This project aims to develop and introduce economically viable value chains based on the use of biochars derived from biomass waste in North-Western European regions.
Sponsor: University of Kassel, Germany

THREEC PROJECT NEWS
Two types of biochars, produced from flax shives and beech wood residues, were evaluated for their adsorption capacity towards 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 to 250°C under atmospheric conditions was carried out to modify the surface functionality of the materials. Oxidized biochars showed a high specific surface area compared with untreated biochars. The Langmuir model showed the best fitting approach to isothermal MB and CMZ adsorption data. The effect of pH, adsorbent doses, initial MB and CMZ concentrations on adsorption efficiency was also discussed.
