Circular wastewater treatment: Extracting biopolymers from wastewater sludge in Campinas, Brazil

TU Delft (
Academic institution
)
#SDGAction51999
    Description
    Description

    o With partners from the private and public sector, a demonstration installation for the extraction of a valuable biopolymer from sewage sludge will be brought from Europe to Brazil. The installation was build in the TU led and EU financed Water Mining project and will be implemented for the first time outside Europe.

    o The biopolymer offers a green, sustainable and novel material, which will create local value chains. The polymer is anyway formed biologically during the treatment process and currently disposed. One of our partners is commercially using the polymer in agricultural applications. The polymer is a raw product for the production of other materials. It replaces oil-derived materials and higher value applications are possible, such as for the production of flame resistant materials or construction material.

    o In addition, nutrients recovery can be integrated in the biopolymer extraction process. The technology is ‘easy-to-implement’ and ‘scalable’ to wastewater treatment for urban and industrial uses. The demonstration unit comes with a multidisciplinary approach. This approach, established in the Water Mining project, will be replicated in Brazil. In the multidisciplinary, multinational Water Mining project the installation was built and was tested in Portugal. In parallel social, governance, economic and educational needs were addressed.

    o The development of local value chains will provide economic incentives to build and maintain wastewater collection and treatment systems all over the world. We see our approach as a model for other places in the global south: Recovering resources from wastewater for high value application to provide economic incentive for sanitation.

    o The objective is to bring the biopolymer extraction plant to Brazil and establish partnerships with local authorities, academic institutions and private industry to catalyze the development of local value chains. The project serves as a showcase to promote circular wastewater and water treatment all over the globe.

    Expected Impact

    o Imagine what it means for sanitation worldwide when wastewater treatment returns more clean water, costs less energy and earns income from recovered materials. In projects such as Water Mining we jointly design sustainable resource recovery to give water and wastewater treatment an economic drive in different locations. The resources are so valuable that the wastewater treatment and desalination plants can be adapted to provide the higher water returns and energy savings. Our joint findings will stimulate circular water and wastewater treatment all over the world, and help improving local industry and agriculture. It is time to reproduce our technologies and approach with partners outside Europe.

    o Our work is addressing the SDGs 6, 8, 9, 10, 17. Our approach is directly linked to sanitation (SDG6). The creation of sustainable / circular economies with development of labour, manufacturing sites and knowledge clusters will remain local due to the local production and treatment of wastewater. We expect site specific products to be developed locally addressing SDGs 8, 9 and 10. We look forward to exchange and share our knowledge with people from all over the world with different interests, professions and needs to improve sanitation. Our work relies on partnership and is in line with the vision of SDG 17.
