Company profile
researched Sep 2026geoFluxus operates a software platform that collects, standardizes and verifies waste and material flow data for companies and public sector bodies. Customers upload or email invoices, weighing tickets and bills of lading, or connect the platform directly to their ERP and internal systems; the company's DocumentAI component reads these documents, and machine-learning algorithms classify waste streams, fill data gaps and link waste streams to processors and treatment methods. Records are combined with data from national waste registers, checked automatically for missing values, duplicates, mismatched classifications and implausible quantities, and validated by in-house waste experts before entering reports.
The platform's outputs cover compliance reporting (CSRD, ISO 14001 and national waste reporting) with traceability from each datapoint back to its source document, circular performance tracking (recycling, separation and landfill rates by site and waste stream), and optimization analysis of treatment routes, transport distances and processor performance to identify cost, carbon and circularity improvement opportunities. A separate public sector product, MonitorCE, gives municipalities and provinces a view of regional material and waste flows, benchmarking and circular economy policy evaluation, and can be published externally. MonitorCE reporting is organised around six circular economy indicators: DMI/DMC, RMI/RMC, potential for better waste treatment, CO2 exposure, an environmental cost indicator, and delivery (in)certainty. The company states it is ISO 27001 certified and GDPR compliant.
Founding story
geoFluxus was founded in 2020 as a spin-off of Delft University of Technology, emerging from PhD research begun in 2016 by founders Arnout Sabbe and Rusnė Šilerytė. In 2019, on commission from the City of Amsterdam, the team developed what it describes as the world's first monitor for the circular economy. The company's name combines "geo" with "fluxus", referring to the movement and transformation of waste.
