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.
