List of Emerging Eco-technologies

The BONUS RETURN project launched the Nutrients and Carbon Reuse Challenge in December 2017 to identify eco-technologies capable of transforming nutrients and carbon into benefits. Out of 13 applications, three winners—Biophree, TerraNovaUltra, and Ravita—were selected based on criteria including relevance, sustainability, and market potential. These technologies focus on recovering phosphorus and carbon from wastewater and agricultural sectors to support the Baltic Sea Region's environmental goals.

• The Nutrients and Carbon Reuse Challenge sought eco-technologies that could reuse nutrients and carbon, specifically targeting those with a Technology Readiness Level (TRL) of 5 or higher according to the EU H2020 framework.
• A total of 13 applications were submitted to the Innovation Challenge, from which four finalists were shortlisted to present at the Baltic Sea Future Conference in Stockholm on March 8, 2018.
• Three technologies were selected as winners to participate in the BONUS RETURN pre-commercialization process: Biophree, TerraNovaUltra, and Ravita.
• The winning technology Biophree uses ion exchange and adsorption to remove phosphorus from water, recovering it as dissolved phosphate for use in fertilizer production.
• The winning technology TerraNovaUltra employs Hydrothermal Carbonization (HTC) to treat wastewater sludge, producing bio coal for fuel and recovering phosphorus as struvite and apatite.
• The winning technology Ravita recovers phosphorus as phosphorus acid from sludge through a patented separation process, creating a high-value product for the fertilizer industry.
• The selection process evaluated candidates based on four primary dimensions: relevance, expected impact, sustainability, and market potential.
