Context: European Green Deal 2019 (1)
Farm-to-Fork Strategy 2
and
Biodiversity Strategy 3
both fix this target for 2030:
- reduce nutrient losses by at least -50%
while ensuring no deterioration on soil fertility
- resulting in a reduction in fertiliser use
by at least -20%

phosphorus recycling becomes obligatory by 2026
from sewage sludge incineration ash* and meat and bone meal ash
* Switzerland banned land use of sewage biosolids in 2006
Germany
• AbfKlärV 2017 (sewage sludge regulation):
phosphorus recycling from sewage becomes obligatory
- by 2029 / 2032 years for all WWTPs > 100 000 P.E. / 50 000 P.E.
if sewage sludge P > 2% of dry matter
Austria (draft notified)

EU Water Policy
Water Framework Directive:
2019 «Fitness Check » (REFIT)
fit for purpose with room for improvement on
investments, implementation, integrating water into
other policies, chemical pollution, administrative
simplification and digitalisation. (ESPP eNews 39)
But only half of EU waters have achieved Good
Ecological Status and several JRC publications
suggest current actions insufficient

• “Extended Producer Responsibility”
- for pharmaceuticals & cosmetics only (initially)
• Measurement methods for microplastics in ww and in sludge
• Promote water reuse
• “integrated urban wastewater management plans”
• Definitions of “sludge”, “micro-pollutant”, “antimicrobial resistance”

18
Phosphorus and nitrogen reuse and recycling targets (art. 20)
“Member States shall take the necessary measures to ensure that sludge management routes are
conform to the waste hierarchy provided for in Article 4 of Directive 2008/98/EC. Such routes shall
maximize prevention, re-use and recycling of resources and minimize the adverse effects on the
environment.
The Commission is empowered to adopt delegated acts … setting out the minimum reuse and
recycling rates for phosphorus and nitrogen from sludge, in order to take into account
available technologies for phosphorus and nitrogen recovery in sludge”
• Discussion underway in Parliament & Council
• ESPP proposed amendment: widen to recovery anywhere in the treatment plant

19
European Parliament proposed amendments
Delete N and P recovery (212, 1093, 1094)
Widen recovery to ww not only from sludge (ESPP proposal) (193, 196, 216, 1095, 1096)
Fix specified P and N recovery rates
- 50% recovery of both N and P (1102)
- 80% for P (1097)
Framework or market measures for uptake of recovered nutrient products
(194, 196, 1095, 1102, 1103, 1104)
Include N2O in climate emission monitoring

“Optional harmonisation”
You can place on the market
 as CE-mark fertilising products
(EU Fertilising Products Regulation criteria – and Conformity Assessment)
 transport to and sell in any EU country
 as “national” fertiliser
 cannot be transported to another EU country
(unless “mutual recognition”)
 or both
 or spread under national “waste” legislation or similar
(traceability, producer responsibility, …)

Recycled nutrients authorised in EU “Organic Farming”
EU Implementing Regulation on Organic Farming 2021/1165 Annex II
In some cases with use, contaminant or origin limitations
• Materials from plants or algae
• Manure (and Cat 2 – 3 animal by-products)
inc. dried, composted, digestate “Factory farming origin forbidden”
• Compost or digestate of separately collected biowaste, or of vegetable materials,
• Various specific animal-by-products:
fish meal, meat meat, bone meal, hydrolysed proteins, dairy, wool, feathers, …
• Wood by-products and ashes, plant processing by-products
• Shellfish and mollusc wastes from “Organic or sustainable fisheries”
• Egg shells “Factory farming origin forbidden”
• Biochar from plant materials
Discussion underway to
define what this means

32
EGTOP Opinions on recycled nutrient materials
EU Expert Group on Organic Production (Opinions here)
Positive opinions: June 2022 here
• Struvite and precipitated phosphate salts
(EU FPR CMC12 definition)
• Widen “biowaste” to green wastes, catering food wastes
(conform to Waste Framework Directive)
2016 here: struvite, calcined phosphates from sewage sludge
Negative Opinions:
• June 2022 here: “Animal Bone Biochar”:
no advantage but contaminant risks compared to non-pyrolysed bone meal
• 2018 here: (certain) N-salts from ammonia stripping
See also : ESPP proposals to authorise further recycled nutrient materials in Organic Production here
FiBl paper on conditions for acceptance of recycled phosphorus materials in Organic Farming here
Public consultation on adding
implementing these in the
Regulation open to 21/11/22

Recycled fertilisers in Certified Organic Farming

Recycled nutrients in EU “Organic Farming”
In some cases with use specification, contaminant limitations or specified “sustainable origin”
• Materials from plants or algae “only for Organic” or sustainably collected
• Manure inc. dried, composted, digestate “Factory farming origin forbidden”
• Compost or digestate of separately collected biowaste, of vegetable materials
• Certain animal-by-products: fish meal, meat & bone meal, hydrolysed proteins, dairy, wool, feathers, …

See also : ESPP proposals here - FIBL paper here
Published 17/1/2023
Precedent for nutrients
recovered from sewage

35
Recycled nutrients in EU “Organic Farming”
Struvite and precipitated phosphate salts
• Must meet Fertilising Products Regulations criteria
- includes from sewage / sludge
- does this means “Conformity Assessment” ?
• Manure effectively excluded

ESPP – questions needing work

37
Questions for further work
Need to develop consensus proposals
• Tools / policies for “market pull” for recycled nutrients
- use quotas: fertiliser manufacturers? distributors? farmers?
- economic tools
- public purchasing
- labels
• Targets for nutrient recycling from sewage and other wastewaters:
- definitions of reuse / recovery / recycling
- % targets for P-recovery, N-recovery
- % of total sewage arisings? wwtp inflow ?
