Implementation period

September 2015- March 2016

Scope work

Resilient structure


This project has been funded by the national programme for clusters support “Ayudas a Agrupaciones Empresariales Innovadoras” (AEIs).


This project involves the installation of a plant on a pig farm requiring liquid manure treatment. The original purification system was developed and patented by Ingeobras and has been successfully tested and replicated in terms of the total use of the water to be purified so that there are no discharges of any kind.

The aim is to provide this system with autonomous regulation and operation capacity using different systems based on FIWARE2 technologies with the following objectives:

  • Design and implement a system for monitoring the most relevant magnitudes and states in the purification process (temperatures, pressures, pump status, etc.).
  • Design and implement a remote-control system for plant management based on FIWARE technology, which will also allow the visualisation and analysis of plant data.

On the other hand, the challenge is to value the plant’s outputs applied to the purification of liquid manure to demonstrate both the absence of final waste and the economic profitability of the purification process.


The project scope is divided into several specific objectives:

  1. Development of a monitoring, visualisation and control system for the liquid manure treatment plant based on FIWARE technologies, including the following results:
    •  Obtaining real-time information on system status at different points (temperatures, pressures, pump status, etc.).
    • Analysis of both historical and instantaneous information.
    • Alarm and event management system.
    • Intelligent visualisation.
    • Remote control of the installation (activation of pumps and systems).
  2. Validate the use of “outputs” from the treatment plant: mainly treated water, sludge and lignin, using the following procedures:
    • Selection of irrigation and/or fertigation doses to be applied in horticultural crops.
    • Validation of the effect of lignin as a soil improvement agent.
    • Determining the productive yield of the crop with treatments.
    • Characterisation of the commercial, sanitary and nutritional quality of horticultural crops with treated water.
    • Comparison of water and fertiliser consumption, productivity and product quality compared to traditional crops.
  3. To compare in energy terms the current management scenario with the improved governance management and the use of biogas applied to pig farms through:
    • Energy audit of the farm in the initial situation.
    • Analysis of the energy and economic improvements resulting from the management plan proposed in WP2.
    • Feasibility study on biogas from the liquid manure plant proposed in the WP2 management plan.
  4. Disseminate the project results and, where appropriate, the environmental and economic advantages demonstrated to the target sector (pig farms), allowing more effective access to the market.


In terms of impact, the following pillars are considered:

  • Social impact:
    • Increase in the use of ICT for better control of the plant and its operation, including jobs related to these technologies.
    • Introduction of ICT and new processes in traditional sectors.
    • Increased meat quality through improved animal living conditions.
  • Environmental impact:
    • Elimination of waste generated in a particular facility that currently has treatment needs.
    • Valorisation of the energetic use of waste by reducing current fuel consumption.
    • Reduction in using fertilisers in the agricultural sector by taking advantage of valorising the plant’s outputs.
    • Reducing the use of chlorine and antibiotics for animals and increasing their hygienic conditions.
  • Economic impact:
    • Elimination of the cost of waste treatment by replacing it with the generation of marketable assets.
    • Savings in energy consumption by taking advantage of biogas from treatment.
    • Reduction in plant management costs by taking advantage of the technology.
    • Increased economic benefits for the client (pig farm) in terms of increased production and meat quality by improving the quality of life of the animals.
    • Securing jobs on pig farms. The current situation created by the uncertainty caused by the pollution of aquifers puts the continuity of farms at risk. This new technology will make it possible to secure the future of jobs by securing the future of farms.
  • European impact:
    • Improved competitiveness of farms and industries. The valorisation of by-products will improve the competitiveness of farms. This will increase the chances of selling in foreign markets.
