Advanced Filtration TEchnologies for the Recovery and Later conversIon of relevant Fractions from wastEwater

The AFTERLIFE project proposes a flexible, cost- and resource-efficient process for recovering and valorising the relevant fractions from wastewater. It will represent an advance on existing approaches to wastewater treatment, which rely on physic-chemical and biological methods.

The AFTERLIFE process will separate out the different components of value using a series of membrane filtration units that will separate all the solids in the wastewater. These will then treated to obtain high-pure extracts and metabolites or, alternatively, to be converted into value-added biopolymers; polyhydroxyalkanoates(PHAs).

In addition to the value extracted from the solids, the remaining outflow of the water will be ultrapure and ready for re-use.

The outcome of the project will be focused on:

  • Demonstration of an integrated pilot using real wastewater from three water intensive food processing industries (fruit processing, cheese and sweets manufacturing)
  • Demonstration of the applicability of the recovered compounds and the value added bioproducts in manufacturing environments
OBJECTIVES

The overarching objective of the AFTERLIFE project is to demonstrate, at TRL-5 (TRL = Technology Readiness Level), an innovative wastewater treatment that simultaneously recovers compounds of interest while converting the remaining organic matter into a high-volume added value biopolymer. Specifically, it sets out to:

  • Develop the filtration system for recovering suspended and soluble solids in wastewater by using membrane filtration units.
  • Develop the process for recovering and purifying valuable compounds in the concentrates extracted in the filtration step.
  • Develop an anaerobic/aerobic process for converting the low value-added organic matter into PHAs.
  • Optimise the resources in the process, following a circular economy approach
  • Design and optimise the AFTERLIFE process from a holistic perspective following a Multidisciplinary Design Optimisation (MDO) approach
  • Conduct a demonstration, at a pilot scale, using real industrial wastewater to generate the end products
  • Prove the economic and industrial feasibility for the AFTERLIFE process along with a comprehensive Lifecycle Analysis (LCA) and cost assessment.
  • Promote exploitation of the project’s results and expand its impact.

ACTIVITIES of Bio Base Europe Pilot Plant

  • PHA recovery: BBEPP will improve the recovery step by developing a cost-effective process for the purification of PHAs from fermentation broths to be competitive as a bioplastic in some applications
  • Integrated process design and MDO optimisation:
    • BBEPP will translate the results from the holistic mathematical model into a process design incl. a flow chart and a process and instrumentation diagram
    • BBEPP will prepare a process flow diagram for a commercial plant
  • Pilot deployment and demonstration: BBEPP will build a pilot line and assess the technical feasibility on pilot scale (equivalent to a wastewater conversion of 1 m3/d). The integrated process will be validated at pilot scale with real wastewater from the project partners
