A dvanced composites are the essential building blocks of the modern world. From 70-meter wind turbine blades generating our renewable energy to light- weight airplanes and boats of the future, carbon and glass fibers are essential for building a high-tech, net-zero tomor- row. But exactly because these materials are built to last, mana- ging them presents a complex challenge. The waste problem, however, starts much earlier than decommissioning. In standard manufacturing, up to 30 % of premium composite material is dis- carded as production scrap before a product even leaves the fac- tory floor. Right now, this massive volume of high-value offcuts- alongside end-of-life parts are placed in long-term storage, sent to incinerators, or processed at a high financial cost. And some of those routes are closing as landfilling is rapidly becoming ille- gal; national bans on composite waste in countries like Finland, Austria, and Germany already prohibit dumping fiber-reinfor- ced plastics, and industry groups are pushing for EU-wide bans. While often viewed as a disposal challenge, forward-thinking recyclers are starting to view them as the largest untapped reser- ve of premium secondary materials on the planet: The fibers dis- posed still hold commercial and structural value. Unlocking the value of the fiber faces some hurdles with conventional recy- cling methods: thermal processing requires up to 5.5 kWh per kg just to burn off the resin. On the other hand, conventional mechanical shredding of carbon fiber composite creates highly conductive, hazardous carbon dust that puts facility workers at risk. Carbon Cleanup, the Austrian manufacturer of composite recy- cling robots solves this problem with their high-tech microfacto- ry CARBON EATER, a machine that disrupts the industry. It is a mobile recycling machine, which completely cuts out transport of bulky parts, works highly-automated and generates high-per- formance secondary fibers on site.
Here is how the microfactory CARBON EATER is turning “hard-to-recycle” carbon fiber and glass fiber materials into a high-value secondary resource: ■ No Logistics: By processing composites right at the source material is densified exactly where it sits. This drops transport costs to zero and entirely eliminates emissions and costs caused by transport. ■ Near-Zero Footprint Recycling: Operating at just 0.32 kWh per kg, CARBON EATER delivers a 10x reduction in energy consumption compared to thermal recycling, without the need of any chemicals, water or heat. ■ Maximum Material Recuperation: up to 99 % recuperation, transforming composite waste into high-quality fibers for industrial second-life applications (used as fiber- reinforcement in plastics among others). ■ Full Material Traceability: CARBON EATER’s digital tracking system automatically logs and labels the recovered output at the batch level, ensuring the exact transparency required to satisfy strict compliance and secondary market quality controls.
