AERIS TECNOLOGIAS AMBIENTALES SL

Their core work

AERIS is a Spanish environmental technology SME specializing in wastewater treatment, waste gas treatment, and resource recovery through biological and chemical processes. They develop and apply bioprocess engineering solutions — including bioreactors, immobilized biocatalysts, and advanced oxidation — to remove pollutants and recover valuable materials from waste streams. Their work spans from pharmaceutical micropollutant removal to urban biowaste valorization and circular economy applications for water, nutrients, and carbon.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2017), AERIS focused on foundational environmental monitoring and remediation — arsenic removal from groundwater using nanomaterials and GHG emission control in wastewater treatment plants. From 2018 onward, their work shifted decisively toward circular economy applications: closing water loops, recovering resources (carbon, nutrients, bioplastics) from waste streams, and pharmaceutical micropollutant removal using advanced membrane and oxidation technologies. The trajectory shows a company moving from pollution control toward resource valorization and circular water-waste systems.

AERIS is positioning itself at the intersection of wastewater treatment and circular economy — expect future work in integrated water-waste-energy recovery systems.

How they like to work

AERIS operates exclusively as a participant, never as a coordinator, which suggests they contribute specialized technical capability rather than project management. With 93 unique partners across 22 countries in just 7 projects, they integrate well into large, diverse consortia — their average consortium has over 13 partners. This makes them a reliable, low-friction technical partner who brings environmental engineering depth without competing for leadership roles.

AERIS has built an extensive network of 93 unique partners across 22 countries through 7 projects, giving them broad European and international reach. Their MSCA-RISE projects also connect them to non-EU partners, as shown by the Argentina-focused NANOREMOVAS project.

What sets them apart

AERIS combines hands-on bioprocess engineering with advanced materials expertise — a rare combination in a small SME. While many environmental consultancies focus on monitoring or compliance, AERIS develops and tests actual treatment technologies (bioreactors, nanocomposite membranes, advanced oxidation). Their dual track in MSCA research exchange and Innovation Actions means they bridge academic research and near-market demonstration, making them valuable for consortia that need a partner who can move technology from lab to pilot scale.

Highlights from their portfolio

• HYDROUSA
  Largest single grant (EUR 572,000) — a Mediterranean-scale demonstration of regenerative water reuse business models, signaling AERIS's move toward applied circular economy solutions.
• SCALIBUR
  Tackles the full urban biowaste chain from collection to bioplastics and protein recovery, showing AERIS's breadth beyond just water treatment.
• RECYCLES
  Their most recent project (2020–2025), integrating nitrogen and sulphur cycles for carbon recovery — represents the frontier of their bioprocess engineering expertise.
