ESPP webinar on regulatory questions for nutrient recycling from waste-derived algae
22 March 2021, 09h00 -13h00 (Paris time, CET)
All slides and links to the video recording of the webinar can be found below
- 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
- 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
