CE.20.018 – RENOIR – From Sugars and Electrons to Diacids and Polymers

Route: Circular economy

Cluster question: 017 How can we make chemical and biochemical production processes more sustainable, more efficient, and cleaner?

Over 200 Mt of petrochemical-based polyolefines are being produced each year. Many of these non-biodegradable polymers, after being used only once, end up in natural environment. This mandates improved recycling options for the short-to-midterm, but also biodegradable alternatives to synthetic polyolefines for the longer-term. Biobased polycondensates have a high potential to ultimately replace polyolefins due to their superior recyclability and reduced CO2-footprint. Such products should be based upon the most widely available biomass feedstock -carbohydrates- and converted into suitable building blocks and polymers using sustainable mild methods. Electrochemistry enables production of unique chemicals via fewer conversion steps and/or more benign conditions. Furthermore, it utilizes cheap renewable energy to drive chemical transformation. Within RENOIR, electrosynthetic and electrocatalytic routes towards eco-efficient and cost-effective processes are developed for the production of both drop-in and new aliphatic diacids from sugar. To encourage technology development and facilitate market introduction, initial focus is on high-value applications, e.g. high-performance polymers and fragrances. Mid-to-longer-term focus will be given on polycondensates based on long-chain diacids having polyolefin-like properties. The large market potential of the derived products benefit from increased circularity and substantial CO2-reduction.
A basic process design and techno-economic evaluation will be used for future research in order to yield cost-competitive processes and products. Enabling the production of sugar-based aliphatic diacids and materials will valorise sugar-based feedstock in the EU, simultaneously reducing its’ dependence on non-EU feedstock. This will strengthen Dutch and European biobased industry and increase circularity and CO2-reduction within the plastic and chemical industry. Societal aspects such as public perception and consumer acceptance of the new technology will also be part of the project.
