ESPP webinar on regulatory questions for nutrient recycling from waste-derived algae

22 March 2021, 09h00 -13h00 (Paris time, CET) - Website 

Registration: coming soon

Objectives:

  • Identify regulatory obstacles to nutrient recycling/reuse from waste-derived algae / micro-algae, i.e. which either have had ‘waste’ status or which are grown using waste inputs
  • Outline potential valorisation routes, current status of development and market potential, important risk questions (contaminants, safety)
  • Propose possible approaches to address key regulatory questions identified

Examples

  • algae grown using waste as a substrate, e.g. grown in municipal or industrial wastewater, in manure or food waste liquors, in digestates derived from such wastes, or fed by offgases (CO2 and/or NOx emissions mitigation),
  • valorisation of the algae themselves (e.g. after ‘mechanical’ processing or dying), or of materials or chemicals derived or extracted from the algae,
  • materials left over from processing algae grown for another purpose, e.g. for extraction of pharmaceuticals, biofuels, cosmetics …
  • algae collected from cleaning operations, such as beach cleaning, canal dredging, clarification of eutrophied waters ….

Uses for the algae and derived materials can include:

  • animal feeds
  • fertilising products: nutrient fertilisers, organic soil improvers, crop biostimulants (e.g. humics)
  • industrial products: packaging (fibres), chemicals …
  • applications with specific regulations: cosmetics, pharmaceuticals, human food additives
  • energy use: extraction of biofuels, combustion of biomass
  • combinations of these, e.g. extraction of a substance for a specific use (cosmetics, biofuels) leaving remaining biomass which can be used for a lower grade application, such as animal feed or fertiliser

Proposals for short contributions are welcome, especially real case studies of regulatory questions confronting algae production process or algae-derived products. Contact:
