The Water Environment Federation (WEF) with the North America Sustainable Phosphorus Alliance (SPA) are calling for study proposals (budget 50 000 US$) to identify and analyse phosphorus and nitrogen flow data aggregated for US and Canada wastewater treatment plants (wwtps), with the objective of establishing a mass balance for current levels of phosphorus and nitrogen flows and of recycling/reuse. The report aims to support WEF’s strategic objective to “Collaborate with water sector partners to define and create a bold, aspirational, and public call to action to accelerate resource recovery”. Data should cover influent flows to wwtps, co-digestion of other organics, wwtp effluent discharge, water reuse for irrigation, land use of biosolids, recovered phosphates, recovered energy and energy used.

“Preparation of Baseline Data to Establish the Current Amount of Resource Recovery at Water Resource Recovery Facilities (WRRFs)”, letter proposal submission deadline 28th February 2018 (5 PM EDT).

The European Council (Member States) adopted its position on the Fertilisers Regulation proposal on 20th December. This is not yet published, but has been seen by some stakeholders. Media coverage indicates that Council’s position is to delay the proposed 60 mg/kgPO3 cadmium limit by eight years, then subject any possible reduction to evaluation. The position indirectly recognises the possibility of “Low carbon fertiliser” by specifying pathogen limits for inorganic fertilisers >1% organic carbon. Council proposals on animal by products however pose problems (“Whereas” n°s 10 and 12), as do proposals on digestates and composts (CMC3, CMC5) by requesting prior sanitation for input of animal by products (in particular manure): so effectively requiring ‘double sanitation’. The proposed Regulation now goes to the trilogue process where Parliament and Council negotiate (with support of Commission) to hopefully find a jointly acceptable text, with discussion usually addressing only points included in the amendments of either Council or Parliament.

Conference Symbiosis and Circular Economy in fertilizers Are by-products a thing of the past? Unlocking the new fertilizer Regulation

7 March 2018 (10h-16h), Brussels, Belgium - Flyer - Email - Registration
Organized by Fertilizers Europe.

Every year, millions of tons of valuable by-products are used by industry as raw materials for making high quality finished mineral fertilizers. This one-day event will bring together industry experts, EU legislators and national authorities for presentations of case studies on practical uses of by-products. The participants will have the opportunity for a creative exchange-of-views on different ways to improve the EU Fertilisers Regulation and to ensure a continuation of good circular practices and economy.

The morning session will highlight viewpoints from professionals working in industrial production and will present practical examples of symbiosis within different fertiliser industry sectors. The afternoon will feature EU decision makers in this area, and will include a panel debate which will aim to find a solution within the political spectrum on the use of byproducts and industrial symbiosis.

The European Commission (JRC) circulated on 20th December 2017, for comment, a DRAFT “market study” (165 pages) for the ‘STRUBIAS’ recycled nutrient products (precipitated phosphate salts, ashes and processed ash products, biochars and pyrolysis products). This document provides the economic and market assessment necessary to justify future addition of these products to the (revised) EU Fertilisers Regulation annexes (as additional CMCs). This is the second part of JRC’s ‘STRUBIAS’ draft report, in complement to a first technical report (“draft recovery rules”, circulated May 2017).

The JRC draft “market study” assesses the possible sources of raw materials for nutrient recycling, STRUBIAS technologies and economic aspects (fertiliser prices, market for STRUBIAS products, economic externalities). Conclusions are that STRUBIAS recycled nutrient products could potentially substitute 25-40% of EU mineral phosphate fertiliser use. Meta-analyses conclude that struvite offers very good fertiliser effectiveness (as good as or better than mineral fertiliser) but that calcium phosphates are less effectives (total 26 studies for phosphate salts), that most ashes/ash based products are reasonable effective fertilisers (17 studies) except for steel slag based materials and non-processed sewage sludge incineration ash, and that data on biochars is inadequate.

JRC requests both detailed comments on the report text (corrections or additional information, line by line) and answers to the following questions. All input should be supported by references to publications or to provided documents:

  • sale prices for STRUBIAS materials
  • costs of regulatory procedures (REACH registration, national fertiliser regulation dossier, industry site authorisation to take in waste materials …)
  • laboratory analysis costs (for the different product criteria, contaminants, etc. proposed in the draft “recovery rules” report)
  • economic impacts of nutrient recovery to STRUBIAS products (environmental benefits, job creation, soil carbon restauration
  • information on metal industry slags (contaminants, fertiliser value …)
  • STRUBIAS nutrient recover routes or raw material sources which are not included in the report, where these are economically feasible and at technology readiness level 6-9
  • market potential of STRUBIAS products other than as P-fertilisers (e.g. as liming materials, soil improvers)

The JRC draft STRUBIAS “market study” open for comment and the detail of JRC’s questions are available on ESPP’s website: (also the May 2017 JRC “draft recovery rules” report and ESPP’s detailed submitted comments 14/9/17). Comments to the draft “market study” are requested by JRC for 15th March 2018. However, comments are not accepted directly by JRC and must be transmitted via a member of the STRUBIAS working group (which includes: ESPP, DPP and several ESPP members). Please therefore transmit your comments to by 28th February latest. For all comments please specify either page number and line number of document, or number of question addressed, and provide justification (references, documents).

ESPP will present and chair during the 6th Sustainable Development in the Food & Beverage Industry Conference, 16-17 January, Berlin (ENG European Networking Group). The conference focusses on the sustainable value chain for food production and consumption. ESPP will address phosphorus, from the field to diet, integrating nutrient stewardship and recycling into food production sustainability criteria. Conference speakers include CEOs and sustainability directors from leading food companies, supermarkets and restaurants, as well as the FAO and the European Commission.

SDFB Conference


The 3rd ManuREsource manure recycling conference brought together 230 participants in Eindhoven, The Netherlands, 27-28 November. This third conference, four years after the first ManuREsource in 2013, confirmed that a range of technologies are today available and proven for manure processing to enable energy recovery and nutrient recycling (see Newtrient catalogue and company success stories below), that the EU regulatory context is evolving considerably, and that the main obstacle to implementation continues to be economic.?

Outcomes of the ManuREsource conference 2017 can be found in our ESPP eNews newsletter no 18.

For the first time ever, a Joint Statement (14 organisations) has been established and signed by key industry federations and stakeholders concerned by the full range of soil improving products, growing media, organic and mineral fertilisers, biostimulants and nutrient recycling. This initiative is co-lead by ESPP (European Sustainable Phosphorus Platform). The Joint Statement underlines that the EU Fertilisers Regulation is strongly awaited by industry and stakeholders to develop the circular economy, and indicates nineteen issues which need to be resolved in the finalisation of the text in “trialogue” (European Parliament, Council and Commission) over the coming months. This follows the vote of the Parliament’s position 24/10/2017 with adoption of the Council position expected soon. The Joint Statement aims to positively contribute to finalisation of the Fertilisers Regulation, to improve dialogue and to achieve a final regulatory text which is workable in implementation, which will facilitate innovation and development of the nutrient circular economy and nutrient stewardship, whilst ensuring the protection of farmers, consumers and the environment.”

The European Commission Joint Research Centre (JRC) organized a Footprint Family workshop, 14-16 November 2017, Ispra (Italy), bringing together specialists from JRC and 11 invited international external experts on footprints. Footprints covered were the ecological, carbon, land, water, nitrogen, phosphorus, energy, material and biodiversity footprints. ESPP joined as expert and brought in knowledge and ideas from the phosphorus footprint perspective. The workshop aimed at creating an internationally recognized scientific panel to discuss synergies and conceptual differences between the different footprints and methods/data used, and to set the basis for footprints related to food production and consumption in the EU. Footprints are analysis and communication tools to assess the impact is of a person, product, company, sector, country in terms of resource use (depletion) and environmental pressure (pollution). The experts concluded that a combination of footprints (footprint family) would provide additional value for researchers, consumers and policymakers to work on sustainable production, consumption and waste management, with a clear link to environmental EU directives and the new UN Sustainable Development Goals. Furthermore it became clear that whereas for example the ecological, land, carbon and water footprint are well developed, for phosphorus and nitrogen there is a strong need for further development, in particular to take into account the virtual phosphorus consumption by imported products. Input on phosphorus and nitrogen footprints and their further development can be sent to

A report for the Netherlands Government assesses possibilities for recovery of nutrients (other than phosphorus and nitrogen) from waste streams. Based on criticality of mineral resources and importance for agriculture, priorities are identified as: boron, cobalt, copper, potassium, molybdenum, selenium and zinc. Waste streams considered include sewage, industrial wastes, municipal solid waste, animal by products, coal ashes and other ashes. The report recommends further research into agricultural use of sewage biosolids (after e.g. composting) but notes the need to address possible risks of organic contaminants. The following recovery routes are identified as having potential: bioleaching and phytoremediation (plant uptake of metals), polymer assisted ultrafiltration (PAUF), fly ash wasting / metal separation (FLUWA) and the Ecophos process (recovery of other nutrients in the residue after phosphorus recovery). Particular potential is noted for zinc and potassium from sewage sludge, Ecophos residues and municipal waste incineration bottom and fly ash (MWIP); copper from MWIP; boron, cobalt and selenium from coal ashes.

ESPP is facilitating at ManuREsource conference (Eindhoven, NL, 27-28 November) a Round Table on the EU Nitrates Directive and manure “in a processed form".

  • This will discuss the possible process to evaluate whether some recycled manure nutrient products should be treated like mineral fertilisers under the Nitrates Directive. The EU Nitrates Committee and the European Commission are considering engaging such an evaluation, possibly looking at the agronomic behaviour, fertiliser efficiency, risk of nitrate or phosphorus losses, and also other environmental impacts such as atmospheric emissions and overall life cycle analysis. The round table will address which manure recovered products could be concerned, definitions and criteria for such products, what data is available or needed. European Commission participation is expected.
  • This round table, 11h-13h on Tuesday 28th November, will be limited to 40 participants. To participate, you must register for ManuREsource then email the organisers indicating your wish to participate in this round table.

ESPP has responded to the European Commission public consultation on policy options to reduce microplastics release to the environment (consultation open to 16th October 2017). ESPP notes that although current concern is principally about microplastics in surface waters and oceans, some microplastics will also be found in organic recycling streams such as sewage biosolids or compost or digestate from food waste. Possible impacts on terrestrial ecology should therefore be studied in order to avoid future obstacles to the nutrient Circular Economy. ESPP suggests to collect data on microplastics in organic recycling streams, develop monitoring methods for microplastics in organic streams and in soils, study their fate and possible impacts in soil/crop systems, investigate possibilities for removing microplastics in organic waste treatment and recycling processes, and develop risk assessments of microplastics in nutrient recycling, in particular to support the EU Fertiliser Regulation.

The European Commission has published an update to the EU Critical Raw Materials list, identifying “raw materials with a high supply-risk and a high economic importance to which reliable and unhindered access is a concern for European industry and value chains”. This third version of the list (first published in 2011, 2014) now lists 27 Critical Raw Materials, following a detailed assessment conducted by external consultants (TNO), Commission expertise and stakeholder consultation, and using a methodology which has been improved to take into account trade factors, different industry sector uses and substitution potential (possible nutrient recycling in the case of phosphate rock). The 2014 list included phosphate rock, representing phosphorus (in any form) essential for food production in mineral fertilisers, animal feed minerals and imported animal fodder. Phosphate rock is maintained in the 2017 list, and following input from ESPP and industry, the specific form white phosphorus (P4) is also added to the list. P4 is essential to a number of added-value chemical sectors, such as fire safety, lubricants, polymer additives, pharmaceuticals, agrochemicals, catalysts, metal processing and is produced in specific production installations. Europe’s last such installation closed in 2012 (Thermphos, NL), leaving these sectors of EU industry totally dependent on imports of P4 or P4 derivatives from Vietnam, China or Kazakhstan. ESPP welcomes the inclusion of P4 onto the Critical Raw Materials list because this will stimulate development of processes to upcycle P4 from secondary raw materials, so contributing to the Nutrient Circular Economy, creating jobs in the EU and reducing import dependency of high-value EU industry sectors. ICL, for example, is developing industrial implementation of the RECOPHOS process, tested at pilot scale in Leoben, Austria, with EU FP7 R&D funding.
