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 www.manuresource2017.org 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.

COM(2017)490 “Communication from the Commission to the European Parliament, the Council, the European Economic and Social Committee and the Committee of the Regions on the 2017 list of Critical Raw Materials for the EU”, 13th September 2017 http://ec.europa.eu/transparency/regdoc/rep/1/2017/EN/COM-2017-490-F1-EN-MAIN-PART-1.PDF

ESPP has submitted comments to the European Commission’s draft proposals for EU criteria for recovered struvite and phosphate salts, recycling of ashes and for biochars, as CE Fertilisers under the revision of the EU Fertilisers Regulation (STRUBIAS). ESPP’s comments include input from stakeholder meeting in Brussels last week, organised by the platform, at which over 100 participants from industry, regulators, EU services, environmental and agricultural NGOs and research discussed the STRUBIAS proposals (slides).  ESPP welcomes that progress is being made towards Europe-wide authorisation of these materials as fertilisers, because this will facilitate the Nutrient Circular Economy, and open the EU market for nutrient recycling technologies. ESPP fully supports the need to ensure that all recycled fertilisers are safe for health and the environment, and offer agronomic qualities for farmers, but suggests that the criteria for recycled products (in CMCs) should not duplicate criteria already applicable to all CE Fertilisers placed on the market (PFCs). ESPP also expresses concern about unnecessary complication and multiplication of criteria which will prevent innovation and confuse implementation, for example for process/time for biochars (instead of using simple indicators of process efficiency in degrading organics, or complex mineral ratios for types of ashes which are already widely used as fertilisers such as meat and bone meal ash). ESPP expresses particular concerns about the proposed criteria for recycling ashes into industrial fertiliser production. This should be an important phosphorus recycling route, as legislation comes into place in Germany and Switzerland requiring phosphorus recycling from sewage, because 2/3 and 100% respectively of sewage sludge is incinerated in these countries, so that phosphorus recovery will be from ash. The wording currently proposed will exclude all phosphorus recycling routes from sewage sludge incineration ashes which are today operational (Zurich process via phosphoric acid production, AshDec thermal recovery, Ecophos process via hydrochloric extraction, use of ash in existing phosphate rock processing fertiliser factories) – not for any reason of safety, but because of inappropriate wording (excluding use of various chemicals in processing) and because of the mechanism of criteria application. This problem is indicative of fundamental cracks in the architecture of the Fertilisers Regulation, similar to overlooking the use of industrial by-products in mineral fertiliser production: the current wording of the Regulation will exclude most phosphate fertilisers currently sold in Europe, because sulfuric acid used in their manufacture is a by-product of oil refining. A European Parliament amendment (IMCO 281) attempts to “patch over” this emission for industrial by-products, but the same flaw poses problems for processing ashes. ESPP believes that use of ashes in fertiliser production processes, to replace imported phosphate rock, should be facilitated by applying the same criteria as for manufacture of fertilisers from virgin materials, subject to ensuring that possible incineration-generated contaminants (dioxins, PAH) are monitored in the ash and not introduced into the environment. This is an important route to accelerate the Nutrient Circular Economy and reduce EU dependency on imported phosphate rock, which is on the EU Critical Raw Materials List.

The European Commission’s STRUBIAS proposals for EU Fertiliser Regulation criteria for struvite / phosphate salts, ashes and biochars, and ESPP’s comments are available at www.phosphorusplatform.eu/regulatory

The EU-funded LIFE project ENRICH (Enhanced Nitrogen and phosphorus Recovery in the value CHain), Sept. 2017 – Feb. 2021, will design, develop and implement integrated nutrient recovery and recycling in the sewage sludge recycling train of the Murcia Este municipal sewage works, Spain (500 000 p.e.) which operates biological phosphate removal. The project will include sludge elutriation to increase availability of soluble phosphorus and so increase the proportion of total sludge phosphorus recovered by struvite precipitation. Additionally are included ion exchange with zeolites (demonstrated high affinity for ammonium) combined with hollow fibre INPI membrane contactors for the recovery of ammonium salts, promotion of digested sewage sludge as a source of nutrients and organic carbon for agriculture, and optimised mixing of struvite – ammonium salts – digested sludge to correspond to agronomic requirements. The recovered products will be tested in field trials and a replicable business model will be developed. Membership of ESPP enables ENRICH to exchange experience with other relevant projects and companies (recycling technology suppliers, organic and mineral fertiliser industries and R&D centres) and to disseminate project results widely, both in Europe and worldwide, through ESPP’s communication tools (eNews, SCOPE Newsletter, website, Twitter) and specialist networks and meetings.

The European Network for Rural Development (ENRD) announced the launch of a new Thematic Group (TG) on ‘Sustainable management of water and soils’ within the broader multi-annual ENRD priority of ‘Supporting the transition to a green economy in rural areas’. This new TG will build upon the work carried out by the TG on Resource Efficient Rural Economy. In this TG, over the past year key rural development stakeholders actively discussed means of support for the integration of resource efficient activities in the implementation of rural development programmes, including topics such as soil, nutrients, carbon and water management (see eNews n° 11 and final TG report pending). The new TG will further investigate how to improve rural development policy implementation. It will work through 2017 and the first half of 2018 with the aim of providing specific recommendations on how Rural Development Programmes (RDPs) can best address issues related to water management, covering both its supply and quality, and soil management in agriculture as well as relevant aspects such as nutrient management plans. The new TG will bring together representatives of different stakeholder and beneficiary organisations, managing authorities and funding agencies, who will come together at regular intervals for four meetings and one final EU-level seminar. The first meeting of the group is planned for the 24th October 2017 in Brussels.

If you are interested in participating in this new TG or wish to be kept informed, please contact , or register athttps://form.jotformpro.com/72183763410958 as soon as possible (preferably by 28th August 2017)

The JRC ‘STRUBIAS’ proposed criteria for integrating ashes (as recycled nutrient fertilisers) into the revised EU Fertiliser Regulation effectively exclude sewage sludge incineration ash. The JRC proposals target only the use of ash directly on fields (e.g. after granulation or blending) but do not cover the use of ash as an input ingredient into a chemical / industrial process. The JRC proposals therefore fix contaminant limits and nutrient plant availability requirements which are appropriate for ash being used directly on fields, but are irrelevant if the ash is being chemically processed (contaminants can be removed, nutrients transformed into different forms). However, fertilisers using ashes as a production ingredient are currently excluded from the revised Fertilisers Regulations (CMC1 excludes wastes as inputs). ESPP has therefore developed proposed criteria for “ash as a process ingredient” to propose to the EU Fertiliser Regulation process. These raise questions concerning End-of-Waste, REACH, fate of removed contaminants and intermediates (e.g. phosphoric acid is recovered from ash, then re-processed to produce fertiliser). Input and comments to these ESPP proposals are invited by email:

JRC proposed Fertiliser Regulation criteria (“nutrient recovery rules”) for struvite (and other phosphate precipitates), biochars and ash (STRUBIAS) and ESPP proposals for “ash-as-an-ingredient” in the revised EU Fertilisers Regulations, for comment www.phosphorusplatform.eu/regulatory

The EU Nitrates Directive specifies application limits for manure “even in a processed form” which are lower than those for mineral fertilisers. This is currently implemented differently across EU Member States, e.g. digestate or compost where manure is only a trace input can be limited as “processed manure”, or mineral fertiliser products produced from manure such as precipitated phosphates or ammonia salts from gas stripping can be subject to lower limits than similar mineral fertilisers produced from virgin materials. This can discriminate against recycled nutrient products made from or partly made from manure, by creating regulatory uncertainty, incoherence between different countries and regions or by more favourable application limits for virgin mineral fertilisers. ESPP is developing proposals to address this, whilst continuing to support the Nitrates Directives objectives of environmental protection and prevention of nutrient losses to surface and ground waters. Input to ESPP’s proposals is invited by email:

The European Commission (JRC) has circulated first draft “nutrient recovery rules” (outline for possible CMC – Component Material Category – criteria under the revised EU Fertilisers Regulation) for struvite (widened to recovered phosphate salts), biochars and pyrolysis products and ashes - STRUBIAS. The report and annexes include a detailed assessment explaining these proposed requirements. It is open to comment and can be consulted on the ESPP website www.phosphorusplatform.eu/regulatory . Please note that the Commission will only accept comments submitted by members of the STRUBIAS Expert Group, which includes ESPP, DPP (German Phosphorus Platform), ECN, EBA, EFPRA, Suez, Vienna City, Italpollina and Fertilisers Europe, as well as Member State representatives. If you have comments, please therefore send to ESPP by end July (), because ESPP must submit consolidated comments in August. This will be discussed at ESPP’s stakeholder meeting with the European Commission on 5th September.

ESPP has submitted comments to the EU public consultation on pharmaceuticals in the environment. ESPP underlines the importance of developing better knowledge concerning presence of pharmaceuticals in sewage biosolids and manures, fate and impact on soils and for agriculture, and removal of pharmaceuticals in sewage and manure treatments (e.g. sewage works, anaerobic digestion, composting). Among these topics there are important questions to maintaining recycling of sewage biosolids and manures to agriculture (safety, farmer and public confidence).

The European Commission has published a proposed ‘roadmap’ for a ‘Strategic approach to pharmaceuticals in the environment’, open for public comment to 26th May 2017. The three page document specifies the relevant EU regulatory framework, in particular pharmacovigilance, and proposes to address particularly pharmaceuticals in water but also pharmaceuticals in soil as specified by pharmacovigilance. The Commission estimates that EU pharmaceutical consumption doubled from 1990 to 2000 and doubled again from 2000 to 2012. The ‘roadmap’ proposes as main objectives to identify knowledge gaps and solution to fill these, and to protect the environment whilst safeguarding access to effective and appropriate pharmaceutical treatments for humans and animals. Uncertainty about levels of pharmaceuticals in the environment and need for risk assessment are underlined. 

ESPP has submitted comments to the EU public consultation on the CAP (Common Agricultural Policy). ESPP underlines the importance of phosphorus because of global food security and the environmental challenge of eutrophication, and underlines the importance of supporting phosphorus use efficiency and recycling in agriculture, in synergy with nitrogen management and return of organic carbon to soil.  ESPP suggests to include in the CAP criteria and funding for closing nutrient cycles and for nutrient recycling, taking into account quality and safety, and including integration of nutrient management into farm, crop and food product sustainability criteria. Reference is made to the work of ENRD (European Network for Rural Development) working group on Resource Efficiency (underway) and the conclusions of the EIP-AGRI Focus Group 19 on “Recycled Nutrients” (See SCOPE Newsletter n°124).

The George Barley Water Prize (Everglades Foundation) has named its first winner as WETSUS Netherlands, with the NaFRAd project (Natural Flocculation Reversible Adsorption). WETSUS (European Centre of Excellence for Sustainable Water Technology) takes home the US$ 25 000 prize for the Prize Stage 1. After winning Stage 1, the Wetsus team is now preparing its submission for the second stage which requires testing and demonstrating at the laboratory lab scale.

Stage 2 of the Prize is open to organisations worldwide, whether or not they participated in Stage 1. Deadline: 15th July 2017, see below.

The WETSUS NaFRAd technology proposes a combination of flocculation with natural flocculants and reversible adsorption with high capacity iron based adsorbents. This can remove both particulate and soluble phosphorus with minimal waste generation. The phosphorus can be recovered as calcium phosphate for use in the fertiliser industry. These technologies reflect the WETSUS research themes Phosphate Recovery and Natural Flocculants.

WETSUS is a partner of the European Sustainable Phosphorus Platform, and has for example developed with ESPP a regularly updated listing of publications providing overviews and comparisons of phosphorus recovery technologies (http://www.phosphorusplatform.eu > Activities > P-recovery Technology Inventory). WETSUS also regularly provides articles for ESPP’s SCOPE Newsletter reviewing scientific publications on phosphorus recycling technologies.

  • Rocky Mountain Scientific APR – proposes a compound (APR1 beads – a proprietary compound) which enables phosphorus to be removed from water by adsorption/desorption. Contact
  • AquaCal AgBag – uses “biogenic oolitic aragonite”, which means a form of calcium carbonate in spherical grains produced by biological processes (this is not clarified). It is claimed that “adding aragonite into animal and plant nutrition … will mitigate the very generation of phosphorus by livestock and farming activities”. Clarifications have been requested by ESPP, because we do not understand how adding calcium carbonate can have the result that phosphorus going into one end of animals does not come out the other end (phosphorus present in animal feed comes out in manures except for the non significant and essentially non variable amount stocked in bones etc). The answer we received from the company was that this is currently undergoing testing. It is also proposed to install different types of filter bags of aragonite in field drainage or storm water collection to adsorb phosphate. It is indicated that the phosphorus-enriched calcium carbonate can then be used as a fertiliser or soil improver.

  • WAVVE Stream / University of Houston spin-off – using nano-coated polymer beads to adsorb nutrients and heavy metals, with regeneration capabilities. Website: http://wavvestream.com Contact

Biological systems

  • AquaFiber Technologies AquaLutionsTM process – lake water is pumped through a patented unit at the heart of which is a dissolved air flotation unit modified to maximize its efficiency to harvest the smallest algal cells from the lake water. The system also includes gravity pre-separation and biological polishing. Clear, clean and oxygenated water is returned to the source and blue-green algae are removed. The harvested biomass can be used to produce an organic fertiliser or converted to energy. A 14 million litres/day, 0.4 ha footprint (of which 7% for the treatment installation) site has already been tested successfully at Lake Jesup, Florida, 2009-2014. The technology is ready for roll-out and the company offers a “pay for performance” business model. www.aquafiber.com See photo.

  • Phosphorus-hungry microbes (PIARCS) – microbes are used to remove soluble phosphorus from water and stably sequester it as polyphosphate. Advantages over conventional bio-P removal are very rapid phosphate uptake, without subsequent phosphate release. The rapid uptake means that fermenter-grown microbes can be added just prior to flocculation. The polyphosphate rich biomass can be used as organic fertiliser. Contact
  • Wetlaculture (Mitsch) – landscape-scale and mesocosm-scale models integrating wetlands for phosphorus retention with agriculture. Retained phosphorus in the wetlands is directly recycled as fertiliser to crops appropriate for temperate or subtropical region. See photo.

High technology solutions

  • Nutrient Extraction and Recovery Devices (University of Maryland Baltimore County) – selective phosphorus uptake and recovery using ion exchange membranes and high-strength monovalent salt solutions. Contact
  • Waterway Nanoshield (University of Calgary) – phosphorus removal from livestock manure using nanoporous carbon membranes as electro-filters, to clean water and produce “mineral concentrates” of phosphorus and nitrogen which can be redistributed as a fertiliser. Contact
  • Plasma Water Reactor – University of Michigan – plasma injection into water is indicated as having the following effects: changing water chemistry (oxidation states, pH) so initiating precipitation of ions such as phosphates; electrical enhancement of coagulation; generation of ozone, UV … which break down organics. See photo.

Iron-based phosphorus removal

  • Waterloo Biofilter EC-P System – low-energy electrochemistry releases ferrous iron into septic systems or ditch water to remove phosphorus as inert, crystalline iron phosphate minerals (vivianite). This is similar to the use of iron salts for P-removal in sewage works worldwide, but without P-rich sludge production. The process can be modified to recover iron phosphate crystals which are proposed for use as a fertilising soil amendment. www.waterloo-biofilter.com Contact See photo.

  • P removal (University of Miami) – using riparian buffer vegetation zones, waste iron materials from foundries for phosphorus adsorption and plants (reedbed type systems) for final purification stage removing low levels of phosphorus and other pollutants. Contact

  • FIU ROAR (Florida International University) - submission from Everglades region presenting a “holistic approach”. Little technical information. Iron coated fibres used for P-removal – not defined how to dispose of or recycle these fibres after phosphorus uptake.

  • Team blueXgreen - University of Idaho – reactive filtration using iron salts, biochar (from agriculture or forestry greenwaste) and ozone. Two first generations of the technology (ferrous iron and ozone) are operating commercially (Nexom/Blue Water Technologies) with installations up to >50 million litres/day, and are participating in the UK-WIR-CIP2 trials (see ESPP eNEWS n°7). The third generation reactive filtration technology (at pilot stage, see photo) adds biochar as a catalyst and phosphorus adsorbant. This can be recycled as a slow release phosphorus fertiliser which sequesters CO2. Photo: University of Idaho N-E-W Tech™ process research trailer.

ESPP has submitted input to the EU’s public consultation on the REFIT (assessment of fitness for purpose) of the EU Chemical Regulation 1907/2006 (“REACH”). ESPP considers the Regulation as having improved information about chemicals used in Europe, so contributing to public confidence and safety. ESPP’s specific comments noted that the exemption of digestate from REACH should be confirmed; underlined the importance for the nutrient circular economy of Art. 2(7)d which specifies that sites producing “recovered substances” (e.g. struvite recovered from wastewaters) do not have to register under REACH (subject to certain conditions) but noted that clarification is needed to ensure fair sharing of costs and administration for this disposition; and noted that adaptation of REACH should be considered to facilitate registration of recovered nutrient products covered by the EU Fertilisers Regulation (after revision is completed), subject to ensuring safety. REACH is complex to apply to variable or organic substances, such as many recycled nutrient products, and partly inappropriate because it is intended to address the substance, and not impurities, which will be specified in the Fertilisers Regulation.

Following the legislative developments in Switzerland and Germany, Austria is now also opting for madatory P recovery from municipal sewage sludge. The draft Federal Waste Plan 2017 (Bundes-Abfallwirtschaftsplan) includes a ban of direct land application or composting for sewage sludge generated at Wastewater Treatment Plants with capacities of 20,000 p.e. or above within a transition phase of 10 yeras. (see chapter 7.5 in the waste plan part 1, link below). Alternatively, these WWTP will have to recover the P from sludge onsite targeting P contents below 20 g P / kg dry solids or have to deliver their sludge to sludge mono-incinerators. The P is then to be reovered from the sewage sludge ashes obtained. This regulation will cover 90% of the P contained in the Austrian municipal wastewater.

On January 18th, the new sewage sludge ordinance has passed the German cabinet. It is supposed to pass the parliament and Federal Council of Germany before summer. Intended dates are 31 March for the parliament and 12 May for the council. After more than 10 years of revision and heated debates, the new draft of the German sewage sludge ordinance was sent by the Federal Ministry of Environment (BMUB) to the European Commission (EC) for notification at September 26th 2016. The notification to EC is a typical procedure for new Member State regulations according to directive 2015/1535/EU. The EC has approved without remarks by 27 Dec 2016. The content cannot be changed afterwards except for minor adaptions.

Once approved by both chambers, the new sewage sludge ordinance may enter into force by 1st January 2018. This step will make phosphorus (P) recovery from sewage sludge obligatory for all German wastewater treatment plants (WWTP) larger than 50,000 person equivalents (p.e.), equal to ~500 WWTP out of ~9300 WWTP. They will have to recover the phosphorus if the sludge contains more than 2% phosphorus /DS (dry solids) or have to incinerate the sludge in mono-incinerators. Land application of sludge will only be allowed for WWTP < 50,000 p.e. These ~500 WWTP represent roughly 66% of the total phosphorus removed from German wastewater and transferred into the sludge.

The WWTP above 100,000 p.e. will have to fulfill the new phosphorus recovery requirements by 2029, after a 12 years transition period. The WWTP of 50,000 to 100,000 p.e. get three additional years for implementation. All effected WWTP have to develop phosphorus recovery concepts by 2023.

Currently, 26% of sewage sludge is spread on arable land. This fraction is expected to half as a consequence of the new fertilising ordinance (DüV) and sewage sludge ordinance (AbfKlärV) entering into force. The fertilising ordinance is the German implementation of the nitrates directive and will strongly affect sludge disposal and valorisation in Germany already next year.

The previous European Commissioner for Science and Research and then for the Environment,

Janez Potočnik, has joined the Board of the European Sustainable Phosphorus Platform

(ESPP). Mr Potočnik has also previously been a Minister in Slovenia, and is currently Co-Chair of

UNEP International Resource Panel. He will act as an ambassador for sustainable phosphorus

resource management, particularly to national and regional governments, and to the food

industry.

 

ESPP’s General Assembly (1/12/2016, Brussels) elected the following Board:

• President: Ludwig Hermann (Outotec, a global leader in minerals and metals processing technology)

• Treasurer: Bengt Hansen (Kemira, a water treatment chemicals company)

• Secretary : Anders Nättorp (FHNW University of Applied Sciences Northwestern Switzerland)

Herman Walthaus (Netherlands Government)

Christian Kabbe (DPP German Phosphorus Platform)

Fertilizers Europe, the European fertiliser industry federation

Janez Potočnik (proposed by BSAG Baltic Sea Action Group)

 

The General Assembly fixed the following priority actions for the Platform for 2017

- The revision of the EU Fertilisers Regulation, to cover recycled nutrient products, in

particular adding struvite, biochars and ash-based products (currently not covered) and

enabling traceability to ensure safety and confidence in recycled products susceptible to

contain organic contaminants

- Refining justification for maintaining phosphorus / phosphate rock in the EU Critical Raw

Materials list

- Developing standards for secondary nutrient raw materials, to accompany recycling

- Sustainable manure management across Europe

 

Innovation in the chemicals industry

The 2016 General Assembly was followed by a thematic meeting looking at innovation and

sustainability in industrial uses of phosphorus. Sixty participants, mainly from industry, but also

from R&D and the European Commission, explored the wide range of industries in which

phosphorus chemicals are essential, including fire safety, energy storage, electronics, medical

applications, catalysts and lubricants. A number of companies, including Clariant, ICL, Magpie

Polymers, Italmatch, Prayon, ProPHOS and Remondis, presented their actions to make

phosphorus chemistry processes more sustainable.

 

Success stories presented include recycling of phosphorus (from sewage sludge, from spent

fire extinguishers), and the development of phosphorus chemicals with improved health, safety

and sustainability profiles.
