"Policy recommendations for the commercialisation of ALG-AD technology"

Throughout the EU, anaerobic digestion (AD) is widely used as an effective means of managing food waste, livestock waste and other agricultural wastes via their conversion into biogas and nutrient-rich digestate (NRD). Whilst biogas is the primary product of this process, digestate is widely recognised as a valuable by-product and is used across the continent in fertiliser applications. Spreading of digestate is regulated as it can have negative and potentially damaging impacts on the environment, with the most significant risk being eutrophication of water bodies. Therefore, strict limits are imposed on the use of fertilisers around Europe and it is often not possible to return all digestate produced in AD facilities back to land, thus causing a build-up of material with no alternative application.

Throughout the EU, anaerobic digestion
(AD) is widely used as an effective means of
managing food waste, livestock waste and other
agricultural wastes via their conversion into biogas
and nutrient-rich digestate (NRD). Whilst biogas
is the primary product of this process, digestate is
widely recognised as a valuable by-product and is
used across the continent in fertiliser applications.
The spreading of digestate is regulated as it can have
negative and potentially damaging impacts on the
environment, with the most significant risk being
eutrophication of water bodies. Therefore, strict
limits are imposed on the use of fertilisers around
Europe and it is often not possible to return all
digestate produced in AD facilities back to land, thus
causing a build-up of material with no alternative
application.


The Interreg North-West Europe ALG-AD project
intends to integrate NRD-grown microalgae
cultivation systems with existing AD facilities, to
create value from Nutrient-Rich Digestate (NRD) that
is produced in excess of that permitted for landspreading,
and therefore currently has no industrial
application. Soluble nutrients contained within
digestate could be used to feed microalgae, which
in turn, will be used as a sustainable protein source
for animal feed.


This study examines the EU legislation across the
entire microalgae production value chain, focusing
first on how the requirements apply to the use of
microalgae as a ‘feed material’, the main market
being targeted by ALG-AD, before investigating
the regulatory framework for accessing alternative
markets and drawing together a series of policy
recommendations to address the main barriers
identified. The report is intended to inform the project
partners initially, then a broader set of stakeholders
and end-users with an interest in this value chain
