Think Purple, Act Circular

POST-PURPLE aims to transform urban wastewater and organic waste into valuable resources by developing innovative bio-based technologies that produce nutrients, proteins, and microbial biomass, including microalgae and purple bacteria.

POST-PURPLE will enhance the environmental performance of processes that convert organic waste and biomass into valuable products, moving them closer to the ambition of zero waste and zero pollution.

Integrated pollution prevention and control will be advanced within POST-PURPLE to systematically address impacts on soil, water and air quality, as well as noise levels across bio-based systems.

The current photo biorefinery system is designed to go beyond conventional resource recovery by actively addressing environmental externalities. In particular, it targets diffuse waste streams such as dispersed emissions and low concentration residues that are often difficult to capture and utilise.

Within this framework, POST-PURPLE focuses on converting exhaust gases and solid residues into valuable outputs including bio based products, renewable energy carriers, and materials capable of long term carbon storage. This transformation not only creates new resource value from waste but also contributes to a reduction in environmental burdens.

As a result, the system helps mitigate air and water pollution while also significantly decreasing odour emissions, improving overall environmental performance compared to traditional processing approaches.

Collaboration across Europe
15 partners from 9 countries

POST-PURPLE brings together seven actors from academia and research, three industry and technology providers and four public and network organisations.
