OPTISOCHEM goal is to demonstrate the performances, reliability as well as environmental and socio-economic sustainability of the entire value chains, for the transformation of excess wheat straw into bio-Isobutene (bio-IBN) derivatives. To achieve these goals a team of 6 partners, leaders in their field, originating from 4 EU-member states, will join efforts. OPTISOCHEM consists in showcasing the technical accessibility and economical sustainability of the value chains, from wheat straw to 2 different families of chemicals derived from bio-based IBN. These compounds, oligomers (DIB, TIB, TeIB) and polyisobutylenes (PIBs) are currently used in a wide range of applications such as lubricants, adhesives, sealants, flavors & fragrances and substituted phenols. This large market is today supplied entirely by products derived from fossil-based isobutene. Products derived from bio-based IBN, using the same process as fossil-based IBN, and with at least as good performances, would provide a renewable supply. OPTISOCHEM includes the development & up-scaling of bio-IBN production from wheat straw, followed by the production and validation at relevant scale -representative of commercial, established processes- of the bio-based derivatives. To this end, four ambitious objectives were defined: -Demonstrate the production of wheat straw hydrolysate (WSH) and establish a quality standard to feed the IBN fermentation unit, -Demonstrate the production of bio-IBN from WSH at pre-commercial scale, -Demonstrate the quality of end products obtained with bio-IBN as a feedstock and using traditional commercial processes designed for fossil based IBN, -Determine and validate the targeted technical, economic as well as environmental/social sustainability performances to be achieved for a commercial plant project. Related Work packages, tasks, milestones and risks are considered in order to achieve these objectives. OPTISOCHEM project is fully aligned with the call topic.

REWOFUEL goal is to demonstrate the performances, reliability, environmental and socio-economic sustainability of the entire value chain, for the transformation of residual soft-wood into hydrolysate (RWH), conversion of RWH into bio-Isobutene (bio-IBN) by fermentation and further conversion to biofuels. To achieve these goals a team of 11 partners, leaders in their field, originating from 7 EU-member states, will join efforts. REWOFUEL consists in showcasing the value chain, from residual wood to 3 high performance drop-in biofuels derived from bio-IBN. These biofuels are full-bio-ETBE, bio-isooctane and bio-isododecane rich biofuels. This large market is today supplied entirely by products derived from fossil-based IBN. Products derived from bio-based IBN, using the same process as fossil-based IBN, would provide a true renewable alternative. REWOFUEL includes the development & up-scaling of this process and the valorization of coproducts: lignin, microbial biomass, biogas and fertilizers. To this end, four ambitious objectives were defined: -Demonstrate the production of residual wood hydrolysate (RWH) and establish a quality standard to feed the IBN fermentation unit, -Demonstrate the production of bio-IBN-based biofuels from RWH at pre-commercial scale, -Demonstrate the valorization of lignin and other coproducts resulting from the RWH process, -Determine and validate the targeted technical, safety, economic as well as environmental/social sustainability performances to be achieved for a commercial plant. This project aligns with the core innovation strategies of 2 SMEs which are: deconstructing of wood (SEKAB, SWE) and conversion of sugars/hydrolysates into bio-IBN (GBE, FR). These 2 SMEs are already operating a demo plant that they intend to further upgrade within the project. Related Work packages, tasks, milestones and risks are considered in order to achieve these objectives. REWOFUEL project is fully aligned with the call topic.
