Optimising bio-based fertilisers in agriculture
Providing a knowledge basis for new policies
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 818309 (LEX4BIO).

Optimising usage of bio-based fertilisers (BBFs)
Imported mineral phosphate and fossil energy-intensive nitrogen fertilisers cause major detrimental impacts on the environment, whilst nutrient-rich side-streams/organic waste remain under-used.
By optimising usage of bio-based fertilisers (BBF) from side-streams, ensuring their safety, building evidence-based trust in their usage and developing legislative framework for their use, it will be possible to reduce dependence upon mineral/fossil fertilisers, benefiting the environment and the EU’s economy.
LEX4BIO aims to achieve this goal by collecting and processing regional nutrient stock, flow, surplus and deficiency data, and reviewing and assessing the required technological solutions. Socioeconomic benefits and limitations to increase substitution of mineral fertiliser for BBFs will be analysed.
A key result of LEX4BIO will be a universal, science-based toolkit for optimising the use of BBFs in agriculture and to assess their environmental impact in terms of non-renewable energy use, greenhouse gas emissions and LCA impact.

Lex4bio goals in the EU agronomic context
Decrease European dependency on finite apatite-based phosphorus and energy-intensive mineral nitrogen fertiliser
A interdisciplinary and complementary approach, from BBBs identification to assessment, LCA and results’ diffusion
Ensure cross-cooperation & cross-dissemination with a network of EU major players, clusters & projects
Resulting in a new framework for BBFs acceptance
Provide a policy framework for EU’s transition to BBFs, while minimising risks to the environment, ensuring food safety and supply, and protecting human health
21 partners from 14 countries, covering Northern, Southern, Eastern and Western Europe, securing evaluation of BBFs in all relevant climate conditions

Lex4bio in practice
The optimisation of BBFs’ efficiency and safety, legislation, trust building and widespread implementation of their usage resulting from LEX4BIO are expected to positively impact on the environment and economy by reducing dependence upon mineral/fossil fertilisers.

“LEX4BIO supports the transition towards a circular economy by enhancing the use of nutrient-rich side-streams as BBFs. By optimising the use of fertilisers according to crop requirement, environmental impacts can be minimised and agriculture profitability improved”
