Every table welcomes more or less 15 attendees. The description of each table can be find below. 


The registrations are closed.

If you are not subscribed yet to a table, you can join on 12/05 during both sessions any table which is not full or cancelled yet.

Description round tables

Table 1: Success stories from Systemic: nutrient recovery from digestate (Systemic)

Moderators: Marieke Verbeke, VCM (BE) en Kimo van Dijk, WUR (NL)

Round table with demo plants, outreach locations, associated plants discussing what they have learned from SYSTEMIC, feedback on the outcome and what more needs to be done.

Table 2: Nutrient recycling and reuse (Nutri2cycle)

Moderator: Giulia Laura Cancian, European Biogas Association (EBA)

The discussion will initially focus on the general aspects of manure management in Europe together with the evaluation of the Fertilising Product Regulation, challenges and opportunities in Farm to Fork targets and carbon farming practices. Then, the RENURE Report will be assessed to specify its missing points and to provide possible suggestions for improvement at regional and EU levels as well as highlighting supply-demand chain and single market to enable fertilizing products transfer between countries.

This table will be merged with table 7 and will be discussed together.

Table 3: Product Category Rules for bio-based fertilizers. In search of a consensual approach (Fertimanure).

Moderator – Joan Colón Jordà (BETA Tech Center, UVIC-UCC)

The use of waste and residual biomass to produce final marketable fertilizing products that have been wholly or partially derived from biomass is a major opportunity towards a more sustainable and green economy. Life Cycle Assessment (ISO 14040) is a standardized and scientifically accepted methodology to determine the environmental performance of products but, there is still a lack of a specialised official guidance to properly apply LCA on bio-based fertilizers production systems. Because of this, LCA practitioners are facing the challenge of taking many methodological decisions by their own, which results on valid but incomparable results among similar systems and products. This has created confusion among the different stakeholders since the obtained LCA outcomes among common products and systems cannot be easily compared nor communicated. The goal of this round table is to explore the currently applied LCA methodological choices and discuss which of them fit the best for the assessment of bio-based fertilizers. Among other topics this round table will focus on: the definition of a Functional Unit and possible allocation criteria when dealing with multifunctional systems.

Table 4: What constitutes a bio-based fertiliser (Fertimanure)? What is the definition and purpose of a tailor-made fertiliser? Arriving to a consensus on definitions and terminologies which will help define manure or other organic-based fertilising products in the market.

Moderator – Laia Llenas Argelaguet (BETA Tech Center, UVIC-UCC)

European research programs and strategic priorities set by the European Commission and embodied in legislative actions now embrace and emphasize - and in some sense begin to enforce - the circularity of manure resources in agriculture. The H2020 program put a large emphasis on developing fertilising products from recycled materials, including projects represented in this conference. The result is the production of fertilising materials from up-cycled or transformed material.

How can these sub-products be defined in a simple way which separates them from conventional, non-renewable fertilisers? Such terminology is important for innovation actors (industry, academia), and can be helpful for the clarification/definition of CMCs of the Fertilising Product Regulation (FPR, EU2019/1009).

Technological processes and models of production and distribution are also under scrutiny: considering decentralised approaches of materials production, and in search of optimised fertilisation regimes, it is possible to imagine the manufacturing or formulation of fertilisers which are designed to meet the requirements of specific crops in a specific context, in a dynamic and integrated manner. How can we conceptualise both changes in fertilisation programs and the development of products which in this sense are “tailor-made” to pedo-climatic conditions, soil statuses and crop needs and by taking into accounts farmers own (manure) resources?

Table 5: Economical feasible business cases for decentral manure processing (NITROMAN)

Moderator: Harm Wientjes, DLV Advies (NL)

On this round table, a cost-benefit analysis of the production of ammonium salts or mineral concentrates from liquid manure/digestate will be presented. In the meantime, possible options for the valorization of these RENURE products will be evaluated.

Table 6: Autocontrol and certification in the manure processing sector

Moderator: Astrid D’Haene (VCM, BE)

On this round table, autocontrol and certification systems in the manure processing sector will be discussed. The initiatives in The Netherlands (Keurmest, Fertigarant,…) will be compared to the initiatives in Flanders (VLACO,…).

A guide for autocontrol for manure processing installations in Flanders, developed by VCM commissioned by the Flemish Government will be presented. Also CE-certification in line with the Fertilising Product Regulation will be discussed.

Table 7: The link between RENURE and Fertilising Product Regulation (ONLY 11h-12h)

Moderator: Laura van Schöll, Nutrient Management Institute (NMI, NL)

How do the developments between Renure and Fertilising Product Regulation link to each other and what are the next steps in this process to follow?

What are the differences, what are the consequences? Renure is about using, while the FPR is focusing on handling and exporting. Do you need both? And to what extend is the safety of products taken into account in these two or how should it be?

This table will be merged with table 2 and will be discussed together.

Merged table 8 & 9: Dutch Nutrient Deal and framing of manure valorisation in the context of EU policy 

Moderator: Nathalie Tijdink, Dutch Nutrient Platform (NL) and Erik Meers, Ghent University and coordinator of Nutricycle Vlaanderen (BE)

Nutricycle Vlaanderen and the Dutch Nutrient Platform are working on an action plan and a Nutrient Deal, respectively, with the aim to advance the transition towards a circular economy. These will be briefly explained during the round table. Give your input on these plans and get into the discussion on the extent to which manure valorisation can contribute to nutrient recycling goals and how these action plans compare to other initiatives in Europe.

Input from the Round table 7 will be taken along in the discussion

Table 10: The case of Gelderland: lessons learned from Kunstmestvrije Achterhoek

Moderator: Hayo Canter Cremers, Stichting Biomassa (NL)

Just like other regions in the Netherlands, the Achterhoek region (East Netherlands) has a considerable yearly surplus of animal manure. This surplus consists mainly of pig manure and amounts to over 750,000 tons of manure per year. In the past the surplus manure could at (relatively) low costs be transported to the German arable regions bordering the Netherlands in North Rhine-Westphalia and Lower Saxony. Due to changes in the German manure legislation, this has become increasingly difficult since around 2015. At the same time, in the Netherlands there is an increasing social pressure on the agricultural sector to become more sustainable. For a number of ‘Achterhoek’ companies from the feed and manure chain and suppliers of technical equipment, this was reason to work together from 2015 onwards to realise a fertiliser-free Achterhoek. The central idea is to replace the import of artificial fertilisers in the region by sutainable fertilisers regionally produced on basis of minerals recovered from manure, sewage sludge and other biomass residual flows. Partly thanks to intensive cooperation with the Ministry of LNV and experts from Wageningen University & Research, the first practical trials with the green fertiliser GWM were conducted in 2018. By paying a lot of attention to quality, method of administration, control and the customers, GWM was applied to more than 3000 ha of Achterhoek meadows and maize fields last year. The customers paid about the same price per kg N for GWM as for regular fertilizer. The minerals from close to 10% of the yearly surplus manure are now recycled. With the introduction of the new RENURE legislation the model can in principal be scaled up to process the complete yearly manure surplus. During the round table, the success factors and pitfalls of this proces will be discussed. It will also be discussed whether this model for the recycling of minerals can be applied in every region with a manure surplus.  In this development a.o. Groot Zevert Vergisting, Slootsmid Fertiliser Technology, NIjhuis Sauer Industries, ForFarmers, Dorset, Groot Zevert Loonbedrijf, Loonbedrijf Bosch and Wilba Techniek participated.

Table 11: Living Labs

Moderator: Niels Kanters, ZLTO (NL) and Rembert van Noort, NCM (NL)

ZLTO and NCM are working together with partners on a Fieldlab platform with an integrated approach for reducing both ammonia and methane emissions. This not only concerns measures in livestock housing where manure is produced, but focusses on the entire manure valorization chain from production to application. We are convinced that aligning activities within the chain creates opportunities. This potential is currently unexploited or is not facilitated by regulations. As a result, integral innovations are developed slowly or not at all. In the Dutch situation, a site permit is linked to the stable system and not to other emission reducing systems such as manure management, processing, storage or application. We want to achieve a change. A change in which it is rewarding for entrepreneurs to use these innovations. Innovations can be made more interesting for usage by adapting the permit system or by an additional revenue model. In order to achieve progress, we have to work together with policy makers to adopt legislation, developed in practice. This can be achieved by delivering data and practical know-how. The Fieldlab platform we are creating plays an important role here: facilitating innovators, collecting evidence and demonstrating innovations! In the round table discussion, we will shortly introduce the approach of this platform, and are happy to discuss this with you.

Table 12: Success story Cooperl, from waste to value

Moderator : François Teillet / Bertrand Convers

For more than 30 years, the French Cooperative Cooperl, has developed a unique and strong circular economy model to create value from waste towards each step of the pig chain including farms and heavy industries like slaughterhouses.

This round table will focus on the circular economy model from farm to meat processing, in order to create value and reduce carbon footprint.
