Description du projet
Une technologie avancée pour la production de biopétrole
Il existe différentes manières de traiter les eaux usées, comme le fait de détecter et recycler des matériaux utiles au lieu de les jeter. Toutefois, les technologies actuelles de traitement et de gestion des eaux usées ne relèvent pas de grands défis environnementaux, tels que la circularité des nutriments et le changement climatique. Le projet REBOOT, financé par l’UE, propose une technologie avancée qui récupère des matériaux précieux à partir des eaux usées, les traite et génère des combustibles neutres en carbone. La technologie de liquéfaction hydrothermale (LHT) emploie une température et une pression élevées pour produire du biopétrole, un produit doté de propriétés similaires à celles du pétrole. Le biopétrole peut être utilisé dans un éventail d’applications avancées comme le biobitume ou des carburants renouvelables pour les avions. La technologie sera testée au sein de réacteurs continus pilotes dans l’objectif de fournir un nouveau concept de gestion des déchets.
Objectif
The REBOOT project will create a disruptive wet waste valorisation technology where valuable resources are re-used rather than disposed of while tackling two urgent environmental challenges: nutrient circularity and climate change. Wastewater treatment sludge and manure treatment technologies are currently not satisfactory and there is no solution to efficiently re-use the resources it contains: phosphorous and carbon.
The aim of REBOOT is to completely recover phosphorous from wastes while generating carbon neutral transportation fuels and a carbon sink in the form of carbon materials. The project will employ a frontier technology called hydrothermal liquefaction (HTL) which uses high temperature and pressure to produce a liquid product similar to petroleum termed bio-crude. This will be used for a range of innovative applications such as renewable aviation fuel, functionalized carbon materials and bio-bitumen.
The possibility of complete phosphorous recovery in HTL is a completely new concept, previously thought impossible as only continuous HTL reactors can theoretically achieve this. The complex hydrothermal chemistry of salts can only be exploited on such advanced reactors that are currently beyond state-of-the-art. The specific objectives of REBOOT are: (1) mechanistic understanding of salt behaviour in multi-phase hydrothermal systems with the aim of full recovery. (2) Develop tailored strategies for in-situ jet fuel synthesis. (3) Establish microbial electrolysis cells for in-situ hydrogen production and nutrient recovery.
REBOOT will be carried out on pilot continuous reactors, where the challenging physical conditions can be explored, exploited and new engineering solutions developed. If REBOOT is successful it will enable society to tackle existing waste problems while recovering nutrients and producing renewable materials, replacing fossil derived ones; representing a revolutionary solution to wet waste management in the emerging circular bio-economy.
