UPSTREAM: UPSTREAM delivers Circular and Bio-Based Solutions for the Ultimate Prevention of Plastics in Rivers Integrated with Elimination And Monitoring Technologies. It aims to overcome challenges related to the monitoring, prevention, elimination, and valorisation of litter (L), plastics (P), and microplastics (MP). Demonstrating a suite of 14 solutions addressing pollution at every step in the water system, connected to 7 rivers in 5 countries, will enable the co-creation of an extensive database of knowledge and sustainable business models with a focus on making information as widely accessible as possible. The involvement of wastewater treatment plant (WWTP) owners, industrial partners with existing supply chains, innovative SMEs, and a water cluster association will ensure exploitation of the project solutions. The UPSTREAM consortium will thus establish circular value chains with the potential to decrease plastic litter by 50% and MP pollution by 30%. (2023-2027).
DigiLignin: Digitalization tools are expected to speed-up PU systems design with respect to properties and processes. To do so, structure-property relations and process models must be developed from theory rather than extensive experimentation. The DigiLignin project addresses these challenges of lignin-based PU design by creating a model that could predict the structure-property relationships via a combined Machine Learning (ML) and quantum mechanical (QM) modelling approach. This ML-QM model will be considered as a robust digital building block to facilitate and speed-up the design of lignin-PU. Overall, DigiLignin promises to rationalize the design of lignin-PU and to accelerate the commercialization of more sustainable materials with lower carbon footprints. In the future, the predictive model could be extended and shared via user-friendly apps with PU users for a wide range of applications. DIGILIGNIN is a FWO project, awarded the Bioeconomy Label by Vlaio, where VITO, UHasselt and Maatsricht University closely work together (2023-2024).
CHRONICLE: Develop a novel chemical recycling approach to process rigid polyurethane (PU) and polyisocyanurate (PIR) end-of-life materials. By using selective depolymerization, we will transform these wastes into valuable building blocks to produce more sustainable materials, guaranteeing in this way a high carbon circularity. To secure the sustainability of the new technological route, CHRONICLE will also have a strong value chain management supported by techno-economic and life cycle assessment. CHRONICLE will link waste providers and recyclers, with downstream chemical companies and PU producers, resulting in an optimized value chain with enhanced circularity, new economic opportunities and new synergetic partnerships. CHRONICE is a part of the Moonshot program, where VITO, KUL and UA join forces. (2023-2027).
FIREFLY: The FIREFLY project is the pioneering research initiative set off to drive the catalyst-based chemical industry towards electrification and to reduce external reliance on metals and fossil fuels. The current production of metal-based catalysts relies mainly on procedures that are not sustainable, as they intensively consume chemicals and non-renewable energy, under harsh operating conditions. The FIREFLY concept uses electricity issued from RES to manufacture (electro)catalysts from secondary resources, in a new sustainable approach that will significantly reduce production costs. The initiative continues the path to circularity, introducing more profitable routes for the chemical industry by using mainly spent, waste, and off-specifications catalysts from different industrial applications, including lignin depolymerization (2023-2027).
- PROMIS: PROMIS will help the chemicals and materials industries in the production of more sustainable polyurethanes (PUs). Using inventive organic chemistry and catalysis, novel bio-based PU building blocks, called isocyanates, will be designed. As a result, current challenges in polyurethane industry will be addressed through closely interlinked valorisation goals. Currently, commercially available isocyanates originate from petroleum resources and are thus non-renewable. To replace these petrochemical isocyanates, PROMIS will investigate the design of new or “lookalike” bio-based isocyanates originating from biomass sources. Their molecular structure and chemical reactivity will be compared to the commercial benchmarks, identifying their potential as drop-ins or superior substitutes. PROMIS aims at the production of these new bio-based structures with distinct reactivities and/or extra beneficial properties (e.g. oxidative & UV stability and/or reduced (eco)toxicity). PROMIS is an intercluster SBO, awarded the Bioeconomy Label by Vlaio, where VITO, KUL and UA join forces (2023-2025).
