Smart Fertirrigation

This project aims to demonstrate the environmental and economic feasibility of an innovative approach to processing digestate from pig manure at biogas plants.

Spain is Europe’s second largest producer of pig meat with 99.561 pig farms and more than 26 million pigs that generate 70 million kg of manure per day (2.7kg/animal per day), leading to important environmental problems. Many anaerobic digestion plants have been established to convert the tremendous amount of pig slurries into biogas and digestate. While biogas can be transformed into renewable energy, the digestate has untapped potential.


This project aims to demonstrate that digestate can be used as a high-quality, suitable and safe biofertiliser by focusing on three specific goals:

  1. Increase the recycling of natural resources in digestate
  2. Substitute mineral fertilisers, lowering their negative impact on the environment
  3. Reduce phosphorous levels in pig manure by testing innovative enzymes in feed

In this way our project will provide significant cost savings to farmers and new income for biogas producers through the enhanced use of natural resources, substitution of the use of mineral fertiliser and minimization of the environmental footprint of agriculture.
