To meet the challenges of agri-environmental transition, the agricultural sector needs to adopt more sustainable practices that reduce pressure on the environment. In this context, the recovery of organic waste such as chicken manure is a key opportunity. Chicken manure, rich in essential nutrients, can be used as fertiliser to improve soils or transformed into biogas, contributing to agricultural and energy sustainability. However, it must be managed carefully to avoid contamination and emissions.

The implementation of appropriate technologies allows for the optimisation of chicken manure use, reducing environmental impact and improving management efficiency. With systems that control emissions and ensure proper nutrient handling, more sustainable poultry production can be promoted and integrated into circular economy models, combining environmental and economic benefits.

Thus, the main objective of the project is to develop a new process based on the integration of the drying and composting processes into a single unit, which allows an organic fertiliser (compost) to be obtained from chicken manure, avoiding or reducing environmental impacts (mainly GHG or NH3 gas emissions, as well as leachates) during the process.

This main objective is broken down into three specific objectives:

• To dry the chicken manure to reduce its volume and decrease the number of transports.
• To validate whether it can be composted after drying.
• To analyse the moisture levels of the chicken manure before and after the drying process.
