Waternet, Amsterdam, has signed a contract with ICL Fertilisers, who will take the recovered struvite produced in the sewage treatment works for use in fertiliser production.
The Waternet sewage works, treats sewage from one million person equivalents (biological nutrient removal) and sludge from two million, incoming from other sewage works (anaerobic digestion). Struvite precipitation (magnesium ammonium phosphate), using the AirPrex process / magnesium chloride dosing in the digestate (anaerobic digester outflow) upstream of the sludge filter press, was installed to address major nuisance incrustation problems in pipes and other installations: operational savings of 200 000 €/year.
The struvite precipitation also improves methane production in the anaerobic digester (possibly by reducing ammonium return streams) and allows biological nutrient removal to achieve phosphorus discharge consent without chemical dosing. The biggest cost benefit comes from improved digestate dewatering (from 20% to 23% dry matter): this results in 300 000 – 400 000 €/year cost savings (gate fee for incineration of sludge in adjacent municipal waste incinerator and lower polymer dosage requirement), effectively resolving dewatering problems which resulted from moving from chemical to biological P removal in the plant.
The Waternet struvite plant started operation in 2013, and has a capacity of 900 tonnes/year. The struvite will now be used in the nearby ICL Fertilisers factory to produce fertilisers, after combination with other minerals.
Ostara are proving that struvite has a real market as a fertiliser. The 150 tonnes struvite/year recovered at Thames Water’s Slough sewage works is being successfully sold to farmers and for turf applications. Demand is exceeding supply and Ostara has even had to import struvite from its several operating plants in North America. Struvite is a slow-release phosphorus & magnesium fertiliser, adapted to plants’ needs for nutrient supply over time. The high quality (purity, granulometry) of Ostara’s CrystalGreen® product is considered by the company to be key to this market success. http://www.crystalgreen.com/
Standards fixed by CEN (Europe) and ISP (global) are important in defining processes and quality criteria in many sectors, including fertilisers, sewage treatment and sludge management, waste incineration, environmental monitoring (see in SCOPE Newsletter n° 112). ESPP is proposing to better integrate nutrient stewardship and recycling into standards development. ESPP is also a member of the EU Industrial Emissions Directive Forum, in order to input on nutrient management in the definition of best practice (BAT BREFs) for sectors such as incineration, sewage treatment, agriculture. Contact the ESPP Secretariat for further information.
After consultation of producers and stakeholders, ESPP has prepared draft outline “fertiliser criteria for recovered struvite”. The objective is to move towards a harmonized recognition of struvite as a fertiliser in the EU Fertiliser Regulation revision process, and for this a definition of what can be sold as “struvite” is necessary. ESPP is asking the EU Commission to now engage an official EU process to fix fertiliser criteria for recovered struvite (JRC consultation process). Download ESPP proposed criteria HERE. All comments on these draft criteria are welcome
ESPP (European Sustainable Phosphorus Platform) has written to the EU Commissioners for Better Regulation, Growth, Environment and Agriculture underlining the economic and job potential of the circular economy for nutrients.
Improving phosphorus use, reducing losses to surface waters and developing recycling can deliver: improvements in water quality, reduced EU dependency on phosphate rock imports, new jobs and economic growth in waste and water treatment, biorefineries and recycling, rural development and “greener” agriculture.
The Platform proposes to include in the new European Commission Circular Economy proposals, expected in 2015: to carry through the revision of the Fertiliser Regulation, to harmonise interpretation of existing legislation, to define a coherent EU policy for phosphorus and to implement market-inciting economic tools.

300 companies, governments, scientists and European institutions met in Berlin 5-6th March to take forward phosphorus management: success stories, policy developments, commercial project launches, a US$ 10 million innovation prize, European Commission / P-REX / ESPP meeting on phosphorus recycling, criteria for recovered phosphate fertilisers, ‘Demitarian’ food. The conference and parallel events conclusions are published in Scope Newsletter_special_n°111 ESPC2 Conference Summary. Overview of all ESPC2 downloadables.
From the 1st of January 2015 it is allowed to use three recovered phosphates (struvite, magnesium phosphate and dicalcium phosphate DCP) as a fertilizer in the Netherlands. This includes recovered phosphates from wastewater and agricultural waste. The Ministry of Economic Affairs has realized this improvement in the fertilizer law in cooperation with the Ministry of Infrastructure and Environment to support the creation of a market for recycled phosphorus. This is a successful result of the Dutch Nutrient Platform’s action since 2011, in particular the Dutch Phosphate Value Chain Agreement signed by more than 20 companies, knowledge institutes, NGO’s and the Netherlands Government. The recovered phosphates are allowed for use as a fertilizer only if the products do not exceed the requirements for heavy metals and organic micro-pollutants applicable for regular fertilizers. For more information (in Dutch) please click here.
Because dosing of magnesium ions is usually required as an input for phosphate
recovery by struvite production, it is important to question whether this poses
issues of possible scarcity of magnesium as a raw material. WssTP and ESPP
have collated information and consulted concerned parties and conclude that the
magnesium ions used for struvite production are not subject to scarcity, although
there may be other cost or LCA issues.
It is also noted that magnesium is a necessary nutrient for plants, so that
magnesium ions used in struvite production are not “lost” but are integrated into
the struvite fertiliser product, where they can have an agronomic value if used appropriately.
German, Flanders and Dutch Phosphorus platforms organise a joint-event for promotion of recycled fertilisers. The "Recycled Phosphate Marketing Event" aims to spread the word about the availability and quality of the secondary phosphates, already produced in several places in Europe. Positive experiences of the farmers with the novel fertilisers are discussed, against the background of phosphorus challenge and possibilities offered by the circular phosphate fertiliser market.
The event takes place on 21st of January 2015 during the world's largest food and agriculture exhibition, The International Green Week, in Berlin and is hosted by the Dutch Embassy. More information.
The European Commission has added phosphate rock to the list of 20 Critical Raw Materials, for which supply security is at risk and economic importance is high. Phosphate rock is identified as non-substitutable and of high economic importance. The updated list results from analysis of 54 non-energy, non-food materials including both abiotic and biotic materials. European policies to address raw materials criticality and dependency include improving efficiency of materials use and recycling, waste policy and international cooperation to address supply security.
Global TraPs www.globaltraps.ch has announced that it will terminate its activities end 2014. Some form of "global phosphorus initiative", bringing together science, regulators and stakeholders, is expected to be launched by then through GPNM (Global Partnership on Nutrient Management, UNEP secretariat).The GPNM phosphorus initiative project is currently being preapred by a team led by Kaj Sanders (Government of the Netherlands, represented by Arnoud Passenier, President of the European Sustainable Phosphorus Partnership ESPP), Terry Roberts (International Plant Nutrition Institute); and Tom Sims (University of Delaware, USA).

The Commission is launching a consultation on how to use phosphorus in a more sustainable way. Phosphorus is widely used in agriculture and is an essential component in fertiliser and animal feed, but it is a resource which has no substitute. Supplies are limited, prices have been volatile and much phosphorus is currently wasted, creating concerns about the cost and availability of futuresupplies in the EU and worldwide. http://ec.europa.eu/environment/natres/phosphorus.htm
The European Sustainable Phosphorus Platform has produced a short outline note estimating potential economic benefits and job creation of P-recycling and P-stewardship. This outline estimate does not claim to be accurate or economically demonstrated because, at present, no coherent data have been collected and no targeted studies are available. Its objective is to solicit further input and comments. Pleas mail your comments to the ESPP team. Download the document ESPP jobs and employment.pdf here
