A meeting was organised by CEN (the European Standardisation Committee) and CENELEC (electrical equipment) on 'Standards for circular economy: waste management and secondary raw materials' in Brussels 8th September. Of around 100 participants, ESPP and the paper industry were maybe the only representatives of the bio-nutrient and bio-materials sector. Yet, the need for standards development to support nutrient recycling and valorisation of bio-waste streams was made clear. Some of the day’s conclusions are strongly applicable to the nutrient circular economy: need to standardise terminology and definitions, including how to measure the recycling rate, importance of public information (e.g. traceability) to develop trust; potential of EN standards to open markets for export; quality standards for input materials, processes and recycled (nutrient) products; benchmarking to indicate for what uses a recycled product is appropriate. The meeting registered that a number of initiatives are underway or expected: EC mandates to CEN for standards development to support the Fertilisers Regulation revision and the EU Circular Economy Package, interface work to identify gaps and incoherence between fertiliser regulations, REACH, waste regulation; BS 8001 proposed standard “Framework for circular economy principles”. This meeting aims to launch a CEN informal process for dialogue on on standards for the circular economy, waste and secondary materials, in which ESPP will actively participate.

Fraunhofer IGB develops and optimizes processes and products for the business areas of medicine, pharmacy, chemistry, the environment and energy. One of the key research areas of Fraunhofer IGB is the development and implementation of cost-efficient strategies and technologies for the integrated management of nutrients from wastewater and organic waste. In recent years, innovative technologies have been developed and demonstrated at laboratory, pilot and industrial scale to recover mineral fertilizers and soil improvers from municipal sewage sludge, livestock manure, digestate from biogas plants and food industry residues. This includes the chemical-free process ePHOS® (presented at IFAT 2016) for phosphorus recovery from sewage sludge and BioEcoSIM for manure valorization. Fraunhofer IGB believes that ESPP offers us a great opportunity to connect with new stakeholders, to strengthen existing partnerships, and help us promote sustainable phosphorus management at the European level. http://www.igb.fraunhofer.de
Maabjerg biogas plant, near Holstebro, Denmark, treats 725 000 t/y animal manures, food industry byproducts, abattoir wastes, sewage biosolids and industry flotation sludge, producing biogas for electricity production and district heating. The manure, food industry and abattoir materials are treated separately, producing 550 000 t/y of liquid ‘Green Line’ liquid digestate and 40 000 t/y fibres, both of which are recycled as fertilisers. A double piping system enables collection of slurry and distribution of liquid digestate with reduced road transport. The biogas plant is estimated to reduce environmental P and N losses by 300 t/y and to maintain 300 local jobs in farming and food processing.

Today over 50% of Sweden’s population is connected to REVAQ certified sewage treatment plants, ensuring continuous quality monitoring of incoming wastewater, sludge digestate quality requirements and transparent information about treatment methods and digestate quality, including traceability of biosolids origins and treatment dates. A key driver of the launch of the REVAQ Certification system in 2008 was the objective to ensure recycling of sewage biosolids phosphorus, nitrogen, micronutrients and organic matter back to agriculture, to provide nutrients and improve soil quality. In 2003, REVAQ Certified digestate contained nearly 3 000 t/y of phosphorus, of which nearly 50% was used in agriculture. REVAQ fixes upstream objectives for source reduction of pollutants, for example aiming to reduce cadmium to ≤17 mgCd/kgP by 2025 (see SCOPE Newsletter n°117 cadmium in artists paints). REVAQ is also working with upstream industries to reduce silver, gold, mercury and organic contaminants in sewage.

Farmers’ cooperative Cooperl has announced investment in a 150 000 t/y input biogas plant, Emeraude-Energy, in Lamballe, Northern Brittany, France. The plant will methanise pig manure and slaughterhouse wastes, producing 79 000 MWh/y equivalent methane, which will be injected into the local natural gas distribution network. Around 610 t/y of phosphorus and 500 t/y of nitrogen in the digestates will be recycled in granulated, nutrient-adjusted organic fertiliser products (production capacity 80 000 t/y). Cooperl already produces such organic fertiliser products from treated manure, adapted to different crops and supplied to France’s agricultural regions which need nutrient inputs for crops such as vineyards, sunflowers, colza, maize. Several hundred thousand tonnes of poultry and pig manures are already processed to fertilisers in Brittany, see SCOPE Newsletter n° 111.

The LIFE+ PHORWater project final conference in Madrid, 14th July 2016, presented DAM (Depuración de Aguas del Mediterráneo) success operating a 20 m3/day struvite recovery stirred reactor, designed by LAGEP Lyon, at Calahorra, Rioja, sewage treatment works. The project showed that struvite recovery and nuisance deposit avoidance can be optimised by mixing different sludge/digestate flows, which can also reduce chemical consumption by changing the reactor inflow pH. Field tests of the recovered phosphate are underway on potatoes and wheat in Spain. Bibiana Rodriguez, Magrama (Span Agriculture, Food and Environment Ministry) indicated that to authorise struvite as a fertiliser in Spain, either the EU Fertiliser Regulation revision process could ensure this, or field test data from Spain are needed to show fertiliser efficiency, as well as data showing safety and product analytical methods, in order to enable struvite to obtain end-of-waste status and be listed as an acceptable waste material for use on soils. The ReVaWaste LIFE+ project (Valladolid, Spain was presented (energy, organic carbon and struvite recovery from different organic wastes). The slides of the PHORWater conferences online now include presentations of experience by leading struvite recovery technology suppliers who participated, in addition to PHORWater: NuReSys, Veolia (Struvia), Suez (Phosphogreen), Naskeo and (see Amersfoort LIFE+) Ostara (CrystalGreen). http://phorwater.eu/en/
Ductor Corp., Finland, has announced its first commercial installation in Germany, at Haren (Emsland, Lower Saxony), designed to replace maize silage in biogas production (expensive and competes with food production) by chicken manure, with ammonia removal and recovery (as ammonia or ammonia sulphate). The Ductor fermentation system removes ammonia upstream of the anaerobic digester, so enabling biogas production from high N manures. The Haren unit, realised jointly with Rücken and Partner Group (R&P), is planned to treat 10 000 tonnes/year of chicken manure and recover 350 tN/year. The digestate can be neutralised with potassium hydroxide to produce a P-K fertiliser. Ductor was awarded GCCA (Global Cleantech Cluster Association) Top 10 in 2015. See here to attend the plant inauguration 30th September 2016. www.ductor.com
In 2014, the EU exceeded for the first time its ammonia emissions (NH3) limit fixed under the Gothenberg Protocol to the UNECE Long-Range Transboundary Air Pollution Convention (LRTAP). Germany, Finland, Spain and the Netherlands also exceeded their individual ammonia emissions ceilings (by 35%, 14%, 5% and 5%). EU ammonia emissions increased by 0.9% from 2013 to 2014. The European Environment Agency indicates that 94% of EU ammonia emissions come from agriculture. This EU failure to respect its international obligations can be expected to progressively put pressure, via future revisions of the National Emission Ceilings Directive (NEC), to prevent ammonia emissions in manure storage, treatment and spreading, and so provide a driver for nitrogen recovery and recycling.

The EU funded EIP Raw Materials (European Innovation Partnership) has published a 108 page “Raw Materials Scoreboard”. Phosphate rock, despite being on the EU Critical Raw Materials list since 2014, is only mentioned five times (plus two mentions to specify that phosphate rock was not covered). Phosphors (as used in lights, LEDs …) are mentioned but these should not be confused, they are based on different metals and not phosphorus. Phosphate rock world production is shown to be 70% concentrated in China, USA and Mongolia (Mongolia produces “phosphor” metals, for phosphate rock it should read: Morocco), which is conform to USGS data, but does not take into account the possibly higher geopolitical concentration of reserves. Phosphate rock is indicated to have only 10-20% “End of Life Recycling Input Rates” EOL-RIR), which is supposed to indicate the percentage of total material input into production coming from recycling. This is misleading: it may be based on the methodology of the Deloitte MSA report published 2/2016 (see SCOPE Newsletter n° 119 “incorrect and un-useable results”). In reality, nearly 1 800 ktP/y are recycled back to fields as fertiliser from manure, plus around 150 ktP/y from sewage sludge, food wastes and meat and bone meal ash, compared to total net EU consumption (import – export) of around 2 050 ktP/y.

The European Commission’s EIP-AGRI has published an 8-page brochure promoting soil organic carbon “Soil organic matter matters”. This is published by EIP-AGRI following the Focus Groups on ‘Soil Organic Matter content in Mediterranean regions’ and ‘Soil-borne diseases’. It outlines the importance and long-term benefits of organic matter in soil, including nutrient capacity, water retention and drought resistance, reducing soil erosion, soil biological functionality and carbon capture (greenhouse emission mitigation). Scientific data sources and online toolboxes to help farmers restore soil quality are listed. Field cases cite compost and manure application as important routes for improving soil organic matter. The brochure proposes a number of themes for Operational Groups identified by the two Focus Groups. EIP-AGRI https://ec.europa.eu/eip/agriculture/
The Food and Agricultural Organization (UN FAO) launched a Technical Advisory Group (TAG) on Nutrient Cycles Accounting and Impact Assessment (Nutrient TAG) within the Livestock Environmental Assessment and Performance (LEAP) Partnership. ESPP has been selected as a member. The LEAP Partnership members called for recommendations on nutrient accounting and impact assessment, for inclusion into the LEAP guidelines. The TAG will build a global common ground by technical dialogue between relevant scientific communities, practitioners, and LEAP stakeholders. Guidance from the Nutrient TAG will concern livestock supply chains including feed production from croplands and grasslands, production and processing of livestock products. During the first advisory group meeting held at FAO headquarters in Rome, 12 – 14 July, stakeholders discussed the objectives, frameworks and specific issues related to nutrient flow analysis, impact assessment, life cycle analysis and foot printing. ESPP provided a presentation on the need for better Data on Nutrients to Support Stewardship, based on conclusions of the DONUTSS workshop 201, see slides.

Field tests of 3-5 years at 22 UK locations show that food-waste digestate provides plant-available nitrogen, increasing crop yields and that compost from garden green waste / food waste builds soil organic matter more rapidly than manure. Both products also provide phosphorus, potassium and sulphur to crops. The WRAP “DC-Agri” research summary (Feb. 2016) indicates total nutrients in this digestate as 0.5%N (80% readily available), 0.05%-P2O5 and 0.02%K-K2O. The summary provides analysis of crop yields, crop quality, soil organic matter, soil biology and physical properties, soil contaminants, ammonia emissions, greenhouse gases and leaching of P and N. The report underlines the need to respect good practice in application of all organic recycled nutrient materials (composts, digestates, manures) and indications are provided in the WRAP Guides to Good Practice UK DEFRA (ministry for environment, farming and rural affairs) welcomed the report for sustainable farming and renewable fertiliser “helping farmers to grow crops more smartly and efficiently”.

The European Compost Network (ECN) estimates that the processing to recover energy and materials of Europe’s nearly 100 million tonnes/year of biowastes (40% of total wastes) could generate over 90 000 jobs (of which 70 000 in rural areas). Of these jobs, around one third exist already today, and processing the two-thirds of biowastes which are currently not recycled or used would thus generate 60 000 new full-time employment equivalents: see the ECN infographic July 2016. Further, a study by EUNOMIA in the UK suggests that separate collection of food wastes (which makes up 30% of domestic refuse in the UK) would save 12-25€ per household through reduced refuse collection frequency. Businesses producing 1 tonne of food waste per week could save over 2 200 € per year if mandatory collection were implemented.

Nearly 40% of livestock manure was exported away from the world’s grasslands over 1970 – 2005, removing P and N and threatening grasslands fertility, according to a study published in Nature and based on FAOSTAT data. The world’s grassland area is >3 billion hectares, twice the cropland area. Soil P removed from grassland must be replaced by organic and mineral fertiliser inputs. The authors estimate that to support an 80% increase in grass production, for milk and meat, these inputs will have to increase four-fold from 2005 to 2050. Combined with requirements for cropland, they estimate that mineral P fertiliser use must double by 2050 (to 1 200 million tonnes P). They emphasise that a range of nutrient management strategies will be needed to meet this challenge, including manure reuse, reducing food losses, returning nutrients from other organic wastes to land, balanced P fertilisation as well as mineral fertiliser use.

Food waste is currently banned from use in animal feed in the EU (and in some 18 US states), following the Foot and Mouth Disease outbreak transmitted by illegal feeding of uncooked food waste to UK pigs in 2001 (incident which cost the UK around 10 billion €). Japan and Korea, on the other hand, feed 40% of their food waste to pigs after cooking under specific sanitising conditions (70 or 80°C), as does China. A recent study from Cambridge University UK estimates that similar, safe, food waste recycling in the EU could reduce land use of EU pork production by one fifth, i.e. 8 million hectares (half the area of Switzerland), including saving half a million hectares of Brazil soybean. Swill feeding to pigs is also analysed as reducing other environmental impacts (green house emissions, eutrophication), improving farmers’ profitability and improving pork meat quality.

The EU’s ‘Science for Environment Policy’ has published a summary of study by INRA France suggesting that The paper is based on results of monitoring of 600 farms in the Meuse (Northern France) and economic modelling. The price of “fertilisers” is taken as a variable, without distinguishing between phosphorus, nitrogen or other inputs. Demand for fertilisers (in this region) is modelled as expected to increase by 2 – 8% to 2020, driven by increasing prices for colza (rapeseed) resulting from EU biofuels policy. A tax of 50 – 270 €/tonne on fertilisers (not specified which fertilisers) is simulated as appropriate to balance this increase in demand and mitigate possible environmental impacts. The authors note that the French government announced an increase in VAT on fertilisers in 2013, but that this has never been implemented.

The EU 7th FP NEWAPP project (New technological applications for wet biomass waste stream products) has published an 80 page report summarising state-of-the-art of HTC (hydrothermal carbonisation) for conversion of wet biomass wastes to quality carbonaceous products which can be used in metal smelting, water and gas purification (pollutant absorption), animal feed additives or soil improvers. Also, the University of Hohenheim, Fraunhofer ISC (Institute of Silicate Research) and AVA-CO2 have started testing in Karlsruhe, Germany, a pilot plant for P-recovery from sewage sludge. The process combines HTC (hydro thermal carbonisation) pyrolysis, producing a coke-type fuel (“HTC-coal”), acid leaching of phosphorus, nano-filtration, membrane filtration and concentration to generate phosphoric aci, calcium phosphate or struvite. The company’s presentation indicates that the phosphorus is not glassified as can be the case in incineration ash so that the acid leaching requires less chemicals and energy, and that most of the heavy metal contaminants remain in the “coal”. AVA’s Karlsruhe demonstration HTC unit has a capacity of 14 000 litres. www.ava-co2.com
EFSA (European Food Safety Agency) has published 13th July an evaluation of the phosphonate [[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methyl]phosphonate. This organophosphorus chemical is used as a polymerisation additive in PET plastics (poly(ethyleneterephthalate)). EFSA concludes that it is safe for use in contact with food (FCM = food contact material) in this application. The evaluation indicates that no migration out of the plastic was detectable, that tests show no genotoxicity.
“Phosphorus from wastewater to crops: An alternative path involving microalgae”, Biotechnology Advances 2016
A review paper presents the state-of-the-art and knowledge gaps for the use of waste streams to feed micro-algae production. The algae can then be used either to extract chemical products (e.g. polyphosphates) or bio-fuels, or for use as fertilisers. P-uptake by algal cells is an active transport system, because the negative phosphate ion does not passively cross the lipid cell membrane which has a negatively charged inside surface. Phosphorus intake and storage occurs naturally in algae, e.g. species which vertically migrate in lakes to use the P-rich deeper waters and surface light. Selection of algae to accentuate fast growth and high P storage are discussed. Different growth technologies are presented: open ponds, photo-suspension bioreactors, immobilised micro-algae, thin layer systems. Further research is needed on these areas, and on selection of micro-algae to optimise their value as fertilisers, including interactions with soil micro-biology.

On 17th June, Ostara and Vallei Veluwe water board officially inaugurated the 900 tonnes/year Pearl struvite recovery unit at Amersfoort sewage works, treating sewage from 300 000 population equivalent and sewage sludge from 1 million. With EU LIFE supportOn 17th June, Ostara and Vallei Veluwe water board officially inaugurated the 900 tonnes/year Pearl struvite recovery unit at Amersfoort sewage works, treating sewage from 300 000 population equivalent and sewage sludge from 1 million. With EU LIFE support, the water and sewage treatment plant is energy neutral, and uses thermal hydrolysis (ELIQUO) and WASSTRIP to increase soluble phosphorus release. Objective is to recover 40% of works input P as struvite. Robert F. Kennedy Jr. inaugurated the Ostara unit, noting that the company will have units operating in 14 sewage works worldwide by end 2016. The recovered struvite is sold by Ostara as Crystal Green performance fertiliser prills, with granulometry size grades, hardness, low-dusting and salt index conform to fertiliser industry SGN specifications.
The European Commission’s JRC (Joint Research Centre) has launched the official process, mandated by DG GROW, to prepare EU “fertiliser criteria” for struvite, ash-based materials and biochars. A first meeting of the group (“STRUBIAS”) of around 30 experts selected by the Commission to advise this criteria process will take place 5-6 July. ESPP, DPP and Fertilisers Europe are designated to this expert group. The criteria elaborated by JRC will then be submitted to the European Commission for addition as an annex to the revised EU Fertiliser Regulation (once this has been adopted and promulgated). These annexes will be integrated into the Regulation by European Commission without requirement to consult European Council or Parliament. Contact to input.

A draft Bill submitted to the US Congress proposes a 30% investment tax credit (ITC) for biogas production and for manure nutrient recovery installations. The bill would also open to new Clean Energy Bonds. The bill would open ITCs for biogas production which do not generate electricity (e.g. for production of natural gas energy) and would facilitate funding, and so implementation, of nutrient recovery on farms.
US Congress proposed Bill H. R. 5489 “ To amend the Internal Revenue Code of 1986 to make qualified biogas property and qualified manure resource recovery property eligible for the energy credit and to permit new clean renewable energy bonds”

EU Commission call open to 15th September 2016, first phase Expressions of Interest. Innovation Deals are a new EU concept, based on the Netherlands “Green Deals” (see example of North Sea Resources Roundabout in SCOPE Newsletter N° 120). The aim of an Innovation Deals is “in-depth understanding and clarification of how an EU rule or regulation applies. If a rule or regulation is confirmed as an obstacle to innovations … the Deal will make it visible and feed into possible further action”. The Deals “will allow innovators to swiftly address legislative obstacles, shortening the time … to market uptake”. The Deals take the form of voluntary cooperation between the EU, innovators, and national, regional and local authorities and are without EU funding.

Following the proposal submitted by ESPP and 60+ organisations across Europe (SCOPE Newsletter n° 114) to launch, the EU’s EIP-Agri Innovation Partnership has selected the theme Recycled Nutrients for its 19th Focus Group. The first meeting took place 31st May – 1st June. The 20 selected experts include ESPP. Expected outputs of the Focus Groups are “mini-papers” (to be written by the expert group and published by EIP-Agri), proposals for EIP-Agri Operational Groups, which will summarise issues and identify R&D needs (possible input to Horizon 2020) and of dissemination needs and other actions. Possible mini-papers suggested to date cover themes such as: quality and monitoring standards for recycled nutrient products, logistics and flows, end-user requirements (farmers, food industry), P-recovery technologies, regulations, on farm nutrient management tools and practice, soil organic matter, nutrient use efficiency, LCA and environmental impacts of nutrient recycling. Contact for further information or to input.
The United Nations FAO (Food and Agricultural Organisation) LEAP (Livestock Environmental Assessment and Performance) Partnership has selected 31 world-level experts for its “Nutrient cycles accounting and Impact assessment Technical Advisory Group” (TAG), including ESPP’s Kimo Van Dijk. The TAG aims to define nutrient assessment and accounting frameworks for benchmarking environmental performance of livestock production, feeding and processing chains, methods for accounting soil nutrients stock changes, for emissions and for life cycle analysis, proposing indicators to assess phosphorus as critical resource. The first FAO Nutrient TAG meeting will take place in July. Contact to input.
Monopotassium phosphate MKP solution was tested as a fungicide in vitro on apple scab Venturia inaequalis (conidia germination, germ tube elongation) and in the orchard. MKP showed to be relatively ineffective (c. 20% effectiveness), compared to boric acid or commercial fungicide. Previous literature has however shown that MKP can be an effective fungicide against powdery mildew on rose or pepper. None of the treatments had adverse impacts on leaves or fruit.

A 37 day study of 16 early-lactating cows shows that treatment of feed concentrates with lactic acid can improve efficiency of animal feed phosphate use. 5% lactic acid treatment of feed concentrates resulted in the same metabolic and energy efficiency (lower food intake, maintained body weight and milk yield) as 0.8% calcium monophosphate. The authors conclude that the lactic acid feed treatment improves energy and mineral status and can thus reduce feed phosphate requirements, in lactating cows fed high levels of concentrates (47% in this study). There are possible concerns of rumen acidosis, identified in this study but without adverse physiological or performance effects.

France’s national radio, France Info, criticises the failure to act on agricultural nutrients emissions which continue to cause algal blooms on Brittany’s beaches. The 2-minute report and online article “Green Algae in Brittany: Inconvenient Truths” accuses the State and the Brittany Region of covering up health impacts, removing funding from independent scientific investigation and using funding intended to reduce nutrient emissions to subsides increasing the size of pig farms.

A report by Wageningen UR for the Netherlands Ministry for Economics gives data for urban P-flows, information on recent P-recycling development and future perspectives. Only 12% of P in urban waste and wastewater is recycled, mainly from industrial wastewater (2 300 tP/y), particularly food industry sludge. P-recovery in sewage works is developing with struvite recovery, but quantities today are small. A significant increase in P-recover from waste water will result from the SNB – HVC – EcoPhos contract which will concern half of Netherlands sewage sludge from 2018. Today, 2 400 tP/y are lost to surface waters in wwtp discharges. Perspectives discussed include reducing food waste, installing kitchen sink grinders to send food waste to sewage works, source separation of urine in several projects, reducing wwtp discharge concentrations, separating storm waters from wwtp input and incinerating meat and bone meal ash in processing routes where P-recovery is possible.

The Järki project, Finland, has published an assessment of nutrient use in agriculture, recycling potential and markets and of relevant regulation, covering the EU level and seven country cases (Netherlands, Belgium, Germany, Italy, Denmark, Sweden and Finland). The report notes major regional differences in nutrient flows across Europe, and also that EU legislation is implemented differently between Member States and national regulations are also different: e.g. Nitrates Directive, fertiliser spreading, manure processing, livestock production BAT, sewage sludge regulation, national fertiliser regulations, National Ceiling Emissions Directive for ammonia ….

US study shows that nutrients will be a limiting factor for algae biofuel production, unless they are recycled in the process and also recycled nutrients are used as input. The US EISA (Energy Independence and Security Act 2007) targets for biofuel production are considered, assuming a 19 billion litres/year target for algae-based biofuels, based on Chlorella and Nanochloropsis. Catalytic hydrothermal gasification (producing methane and hydrogen from algae) offers the highest potential for nutrient recycling in the biofuel production process. Secondary sources of nutrients are estimated to be sufficient to supply the “new” nutrient input necessary, beyond in-process recycling.

On 17th June, Ostara and Vallei Veluwe water board officially inaugurated the 900 tonnes/year Pearl struvite recovery unit at Amersfoort sewage works, treating sewage from 300.000 population equivalent and sewage sludge from 1 million. With EU LIFE supportOn 17th June, Ostara and Vallei Veluwe water board officially inaugurated the 900 tonnes/year Pearl struvite recovery unit at Amersfoort sewage works, treating sewage from 300.000 population equivalent and sewage sludge from 1 million. With EU LIFE support, the water and sewage treatment plant is energy neutral, and uses thermal hydrolysis (ELIQUO) and WASSTRIP to increase soluble phosphorus release. Objective is to recover 40% of works input P as struvite. Robert F. Kennedy Jr. inaugurated the Ostara unit, noting that the company will have units operating in 14 sewage works worldwide by end 2016. The recovered struvite is sold by Ostara as Crystal Green performance fertiliser prills, with granulometry size grades, hardness, low-dusting and salt index conform to fertiliser industry SGN specifications.

ESPP has submitted first comments on the draft revised EU Fertiliser Regulation. This new text is positive and important step to opening the market for recycling of nutrients and carbon from organic wastes and by-products. ESPP proposes to introduce traceability into the regulation, for products liable to contain organic contaminants from sewage, manures, food wastes and animal by-products, in order to ensure public and food-chain confidence and safety. ESPP also proposes to require demonstration of the agronomic fertiliser effectiveness of recycled nutrient products. In order to enable innovation with new recycled nutrient products, ESPP proposes to clarify the criteria for authorisation of new categories and to already launch work on additional new products: recovered mineral N fertilisers, other phosphates (as well as struvite), processed manure and sewage products. Summary of Fertiliser Regulation proposal text see SCOPE Newsletter 120. ESPP comments here.
Five Live Science, BBC5 Radio UK, has put out an interesting 20 minute roundup of why phosphorus is important, how to reduce uses and losses and opportunities for recycling. Robert Evans, Anglia Ruskin University, explains how Coton near Cambridge used to be the UK’s dinosaur poo capital until resources ran out leaving Europe largely dependent on imports to supply fertilisers and grow food. Pete Vale, Severn Trent Water, presents the beauty of sludge cake, full of natural goodness for crops and healthy soil, and the potential of P-recovery as struvite. James Dyke, Southampton University, discusses the risks of geopolitical concentration of phosphorus rock supply worldwide. John Hammond, Reading University discusses how to better use P in agriculture and in soils, and how to reduce society’s phosphorus needs for exampling by changing diets.

Netherlands Member of the European Parliament, Jan Huitema’s, text calls on the European Commission to revise the EU Fertiliser Regulation , remove barriers in the Nitrates Directive and implement special rural development programmes to stimulate the recycling of nutrients as mineral concentrates from animal manure. This was voted in April 2016 by a large majority of the Parliament Agriculture Committee, in Mr Huitema’s report on innovation and economic development in European farm management (2015/2227). The voted text notes concern that the EU is highly dependent on the import of minerals for fertilisers and the possibility to recover nutrients from animal manures to produce ‘green fertilisers’. Mr Huitema’s website notes that mineral concentrates from manures can make a major contribution to the circular economy, are good for the environment, and avoid natural gas consumption and mineral import for fertiliser manufacture. ESPP note: the EU Fertiliser Regulation revision proposals published 18th March and open to consultation (see SCOPE Newsletter 120) cover digestate and compost produced from manure, but phosphate minerals recovered from manure are not covered (work on struvite is underway) and nitrogen concentrates or chemicals recovered from manure are not yet taken into account. The Nitrates Directive issues with nitrogen minerals recovered from manures are discussed in SCOPE Newsletter 100.
