Producing advanced bio-based fertilizers from fisheries wastes

Periodic Reporting for period 1 - SEA2LAND (Producing advanced bio-based fertilizers from fisheries wastes)

Período documentado: 2021-01-01 hasta 2022-06-30

More than 50% of the fertilisers used in Europe are synthetic fertilisers from third countries (high logistical costs, high GHG emissions and high dependence on third, often unstable countries). Moreover, fossil fertilisers contribute to GHG emissions and at the same time, agriculture demands more than 1,900 tonnes/year of P that are currently obtained from mines, which have a high impact and are non-renewable. An agriculture dependent on others may have problems to produce food in sufficient quantity and at a reasonable price if the market for fertilisers becomes more expensive or destabilised. Society must have a guaranteed food supply without being dependent on third parties who can make the availability of fertilisers more expensive, or use the availability of fertilisers as a commercial weapon.
Besides, each year, the discards from fisheries exceed 20 million t (25% of total catches), and include "non-target" species, fish processing waste and by-products which composition can exceed 9% N, 2% P and 0.6% K.
The general objective of the SEA2LAND project is to provide solutions to help overcome future challenges related to food production, climate change and waste reuse by improving and adapting technologies for nutrient recovery to produce bio-based fertilisers (BBFs) and Tailor Made fertilisers (TMFs) from fishery and aquaculture by-products generated in Europe.
The technical work carried out during this first period (M1-M18) is summarized below:
WP2 ;
Task 2.1 Mapping of European nutrient unbalance. The assessment of nutrient imbalances in European soils is necessary to obtain relevant information for a more rational fertilisation that makes better use of local resources. European Soils Nutrient unbalance mapping has been done based on national, and regional data sources where data from soils, crops, crop, manure etc. were collected, statistically treated and, thus, a nutrients balance and a map for each region (NUT 3) has been calculated.
Task 2.2. End users’ requirements. The objective of this task was to investigate and comprehend the requirements of the end users, farmers and distributors in each region, deepening in the specific characteristics of the agricultural systems and models in each Region using a questionnaire to end users in each Region. As conclusion it can be said that new ecological biostimulants obtained from fishery or aquaculture byproducts will be accepted by European end users.
Task 2.3. Mapping of fisheries and aquaculture side-streams. The objective during this period has been updating the information on the provided side-streams in each SEA2LAND region The volumes available of each side-stream type for their valorisation in each of the studied countries have been estimated.
Task 2.4. Regulatory Task
The objective was to analyse general EU and National/Regional specific regulations affecting the use of fishery and aquaculture by-products for agronomic use and identify the legal requirements that the raw materials and the final products must fulfil. Regulations were analysed.
Task 2.5. Society, consumer
Determining the variables that affect the acceptance of consumers and understanding the reasons of the consumers’ behaviour related to food waste recycling in this way is of great importance to ensure the market uptake of BBF treated products. With this aim, a consumer survey was done in which a total of 1,516 online answers were obtained in the 5 European countries participating in the project: Spain, Italy, France, Estonia and Norway.
2.6 Multi Actor approach. SWOT Analyses.
SWOT analysis gives an overview of internal and external factors for the SEA2LAND case studies and conclusions about the identification of development needs, recommendations to regulatory bodies and a proposal of future actions. A preliminary SWOT has been developed for each of the SEA2LAND case studies (7) has been done.
WP3 and WP4 activities:
With the aim of demonstrate the technical feasibility of the production of fertilisers from different by-products of the fish processing industry, using different technologies and to produce a quantity of end-products (BBF) suitable for their validation through agronomic trials foreseen in WP5 and quality assessment WP6, 7 pilot experiences in the Baltic, Cantabrian, Adriatic Sea Regions North Sea, Atlantic Sea and Mediterranean Sea and a freshwater pilot placed in North Spain are being developed. The main activities for this period of SEA2LAND have been:
1. The characterisation of the side-streams used in SEA2LAND: physical and analytical composition (nutritional and contaminants) and updating the data on their generation (process, volumes, etc.).
2. Testing and adjusting the conditions of the procedures / technologies designed for the production of each of the defined BBF and the IP for their formulation.
3. Up scaling each procedure to produce a quantity of IP and then BBF suitable for the evaluation of the quality and safety assessment of the final products (BBF) in WP6 and for the first agronomic trials (pot testing)
For the rest of the technical WPs, they have just started their activities such as the definition of methodologies, information flows and preparation activities.
Within the WP6 (quality and safety assessment) ,It has been held several meetings where actions and responsibilities were stablished, 6 BBFs have been characterised and the other 6 should be received by UGENT and analysed by mid-September.
In the case of WP7, the social and environmental impact and technic-economic assessment methodology have been defined, preparation meetings have been held and the partners involved are filling in the necessary information questionnaires.
WP8 has not yet started, but stakeholders are being defined for later actions.
During this first period, communication and dissemination activities have been carried out (WP9) including web, dissemination material, image manual, templates, publications and news.
WP10 (Ethics) the deliverables have been released and the confidentiality procedure has been defined
SEA2LAND identifies excess or deficit of nutrients existing in Europe at ninnovatove scale( NUT3) updating existing data and providing it in a visual way. A geographic viewer of imbalances will be published on the website for public use and provide more accurate and more useful data for land management purposes.
SEA2LAND intends to generate 12 new BBF using residues from fishing and aquaculture that have not been used until now.
An in-depth study of its chemical and biological composition will be carried out, as well as, as innovation, the presence and flux of microplastics. The social and environmental impact has been studied to have a complete overview of the entire chain and that will contribute to the definition of circular and sustainable business models.
The technologies developed by the SEA2LAND project could reduce 0.43 million t of imported P (1 million t/year) by 13% and replace it with safe, renewable, P-containing BBFs, i.e. SE2ALAND would provide technologies that, if treating waste 5.000.0000 t, could recover 100,000 tons of P contained in by-products of fishing and aquaculture, this P will serve 1,500,000 ha.
The proposed model of the SEA2LAND project focuses on providing circular and sustainable regional case studies that will be analysed for their replicability in other regions.
