Optisochem

Problem statement

Replacement of fossil intermediates with next generation bio-based drop in (IBN) products.

Executive summary

OPTISOCHEM’s project 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.

Value chain description

The BBI JU OPTISOCHEM project is demonstrating the potential to convert wheat straw to 2 different families of chemicals derived from bio-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.

Market deployment considerations

The global isobutene market size was valued at USD 27.3 billion in 2022 and is anticipated to grow at a compound annual growth rate (CAGR) of 4.4% from 2023 to 2030

Environmental considerations

Significant projected saving in GHG emissions. The project aims to reduce energy consumption by more than 30% for bio-catalytic processes as compared to state-of-the-art production processes. The project also helps to deliver savings, in terms of CO2 emissions per kg product by more than 20% for bio-catalytic as compared to state-of-the-art production methods

Social Considerations

The biorefinery approach could create jobs in rural areas providing farmers with an alternative source of income for their residues.

Stakeholders Involved

Farmers and foresters, technology providers, product market actors (e.g, food industry, manufacturing industries, consumer goods etc.)
