High-Efficiency Light-Driven Micro Reactors for Sustainable Chemical and Pharma Production

manufacturingPrototypeTRL 3

Imagine trying to bake a cake using a flashlight, but the light only hits the surface. This project creates a special glass straw that carries light deep inside the mixture using tiny gold-like particles to spread the energy evenly. It turns a slow, wasteful process into a fast, continuous stream of chemical production.

The business problem

What needed solving

The chemical industry is a major CO2 emitter, and while photochemistry is a greener alternative, it cannot be scaled up because light cannot penetrate deep into large-scale reactors.

The solution

What was built

A fiber-based micro-reactor using plasmonic nanoparticles to distribute light and 3D laser-machined micro-inlets (< 50 µm) for fluid flow.

Pharmaceuticals
enterprise
Target: Drug synthesis manufacturer

If you are a drug synthesis manufacturer dealing with pharmaceutical shortages and inefficient batch processing — this project developed a fibre-based micro reactor that allows for precise light management and continuous flow, increasing reaction yield and safety.

Agrochemicals
mid-size
Target: Pesticide and fertilizer producer

If you are a pesticide producer dealing with high CO2 emissions from traditional heating — this project developed a light-driven reactor that substitutes fossil fuels with sustainable energy sources to prepare agrochemicals.

Environmental Services

Target: Industrial water treatment plant

If you are a water treatment plant dealing with pollutants that require photochemical breakdown — this project developed a micro-scale reactor with < 50 µm inlets that enables high-efficiency water treatment via continuous flow photochemistry.

Frequently asked

Quick answers

What is the cost or price of this technology?

Based on available project data, specific pricing for the reactor is not provided, though the project received an EU contribution of EUR 3,111,973 for development.

Can this be scaled to industrial levels?

Yes, the project specifically addresses the 'missing light management' bottleneck that previously hindered upscaling, aiming for industry-demanded scale-up through the use of specialty optical fibers.

What is the IP or licensing status?

Based on available project data, specific patent or licensing terms are not listed, but the project involves a consortium of 6 partners including an SME and a university.

How does this integrate into existing chemical plants?

The technology replaces traditional batch reactors with a continuous flow system using a monolithic fiber component and laser-based micro-machining for fluid interfacing.

What is the development timeline?

The project is active from 2023-04-01 to 2027-03-31.

Consortium

Who built it

The consortium consists of 6 partners across 4 countries (DE, ES, NL, PL). It is heavily weighted toward research, with 3 universities and 2 research institutions, while industry representation is low at 17% (1 SME). This suggests the project is currently driven by academic discovery with a limited but present bridge to commercial application.
