TORWASH®: A Continuous Hydrothermal Treatment Process for Efficient Dewatering of Industrial Wastewater Sludge
The paper industry generates 400 million tons of wet sludge per year, mainly composed of biological paper sludge, that contains harmful substances and are expensive to dispose of via incineration or landfilling.
Biogas Production Potential from the TORWASH® Filtrates
The F-CUBED project´s pilot tests used three different feedstocks of paper sludge, olive pomace and orange peels which were hydrothermally treated in the TORWASH® reactor and then dewatered and separated into a solid fraction and a liquid filtrate. After treatment, the filtrate still contains organic material that could be used for generating biogas in an anaerobic bioreactor.
Report on continuous operation of the TORWASH® pilot plant for the treatment of fruit & vegetable waste
TNO have submitted their report on the installation and testing of the F-CUBED pilot plant at the Delafruit facility in Selva de la Camp, Spain conducted in April 2022, where orange peels were hydrothermally treated and dewatered using the TORWASH® reactor and the Limburg Filter filter press.
Evaluation of NPK recovery potential from TORWASH®-treated paper sludge, waste olive pomace and fruit & vegetable waste
Submission of the preliminary results for the potential of nutrient recovery from the solid and liquid fractions of the TORWASH ®treated feedstocks
Venice 2022: 9th International Symposium on Energy from Biomass & Waste
F-CUBED presents the preliminary results from the environmental assessment The 9th International Symposium on Energy from Biomass and Waste took place in Venice, Italy from the 21st to the 23rd of November 2022. The event was organized by the International Waste Working Group (IWWG), a scientific and professional forum designed to promote and disseminate new developments in the waste management industry.
F-Cubed: Presentation at Circular Materials Conference
F-CUBED project partner Swerim AB presented their research findings from Work Package 2 “Paper Sludge Treatment” at the Circular Materials Conference held in Skellefteå, Sweden on the 14th and 15th September 2022. The conference is the leading Nordic forum concerning the industrial, scientific and commercial progress of the use of circular materials.
Combustion Testing of Biofuel Pellets
The solid fuel pellets generated from the hydrothermal treatment and dewatering of the paper sludge, olive pomace and orange peel feedstocks have undergone combustion testing led by F-CUBED partner HEAT Systems in Ireland in June 2022. The testing was supported by colleagues from TNO who performed online gas analysis.
F-CUBED and OLEAF4VALUE in Collaboration
The F-CUBED and OLEAF4VALUE projects are collaborating through mutual support and joint communication and dissemination activities to ensure that stakeholders are informed about the technologies and processes being developed in both projects that can help actors in the olive sector transition to more circular, sustainable and profitable business models.
Scientific Publication
Feasibility Study of Bio-Sludge Hydrochar as Blast Furnace Injectant The steel manufacturing industry is one of the largest and most important industrial sectors in the world. However, it is also one of the most energy intensive and highest coal consuming industries which has a significant impact on global CO2 emissions.
F-Cubed: Limburg Filter´s Robust & Advanced Dewatering Technologies
Filtration is a tried and tested process but Limburg Filter are taking this robust technology to a new level, developing custom made products that are more efficient, safer, minimising the impact on the environment and are flexible enough to process a huge range of industrial and manufacturing waste streams.
F-Cubed: TNO´s Torwash Reactor
Alongside Limburg Filter´s filtration technologies, the TNO developed and patented TORWASH treatment is the core technology of the F-CUBED process, enabling the efficient dewatering of a diverse range of industrial and manufacturing waste streams.
The F-CUBED Consortium Meeting M24
F-CUBED consortium members gathered together on the 11th and 12th of April 2022 for the project´s second consortium meeting in the beautiful town of Reus in the province of Tarragona, Spain where it was the first time that the F-CUBED partners were all able to meet in person to discuss the project´s progress.
F-Cubed Joins the Biorefine Cluster Europe
The F-Cubed project is now a proud member of the Biorefine Cluster Europe community.
WP3 - Waste Olive Pomace Treatment
Testing is going well on the second stop of F-Cubed´s European tour at the Appo olive oil facility in Italy.
The pilot campaigns in Sweden
This past august the F-CUBED team worked hard to achieve an important milestone in the project. The TORWASH® pilot plant and the Limburg Filter press were installed on the site of Smurfit Kappa Pitea in Sweden and were prepared to perform the first functional testing.
F-CUBED Consortium Meeting M13
The F-CUBED team got together this past 19 and 20th of May in virtual mode for the M13 Consortium meeting. With a series of group activities and a set of presentations of the members of the project, the team took advantage of the opportunity of the gathering to get more aligned and connected the project activities.
Limburg's Filter Online Training
The F-CUBED team participated this past May on an online training led by Limburg Filter, to address safety aspects of the installation and next steps for the preparation of the pilot campaigns
The F-CUBED team participated in May 2021 in the TORWASH® Online training
The residues in the FCUBED project are treated via TORWASH® reactor technology, patented by TNO, first at laboratory scale and afterwards with the installation of the pilot plant that will be adapted to process flexibly the wet biomass.
The F-CUBED Project Participated in the EUBCE’S 29th European Biomass Conference & Exhibition
Pavlina Nanou, one of our colleagues from TNO discussed in EUBCE2021 the Hydrothermal Conversion of Wet Organic Residues to Intermediate Bioenergy Carriers in the F- CUBED project.
