Circular Economy: How can we make raw materials from organic waste?
Organic waste streams are currently composted, digested or incinerated. The waste management industry would like to do more, in terms of establishing a circular economy. They would prefer these waste streams to be used as building blocks for the chemical industry.
Watch the video below to find out how TNO is shaping this transition, together with various waste management companies, the chemical industry, and other relevant supply chain partners.
Increasing sustainability is one of our greatest societal challenges. An essential element here is the creation of a circular economy – an economic system that maximizes the reusability of products and raw materials while minimizing value destruction. The reuse of waste would be a significant step towards this goal.
Using organic residual streams
Within Biorizon Shared Research Center TNO is working on technology development for the production of bio-aromatics. Organic residual streams can be converted into furans and levulinic acid, which are building blocks for bio-aromatics. Aromatic compounds make up 40 percent of the chemicals in applications. Each year, 90-100 megatonnes of these compounds are used in the manufacture of various products such as plastics, lubricants, coatings and packaging. Waste streams such as manure, SSO (vegetable, garden and fruit waste) sieve fraction and diaper fill can be suitable feedstocks for the production of these chemical building blocks. If the chemical industry were to make full use of such organic residual streams, it would ultimately be possible to achieve a 50-75 percent cut in CO2 emissions. This is motivating many companies, such as Coca-Cola, Unilever and LEGO, to explore these alternative – sustainable – raw materials.

Seeking partners for a pilot plant
TNO is currently working towards a pilot plant to convert organic residual streams into building blocks for bio-aromatics. “We are seeking partners that can supply waste for this plant and chemical companies that would be prepared to use the building blocks we produce”, says TNO’s Monique Wekking. “Cooperation like this can mean increased economies of scale, while providing access to even more practical knowledge from the supply chain.”
