Although these strategies do not include anaerobic digestion in the combination of processes and therefore do not take advantage of its benefits, they do provide a higher organic matter content in the recovered effluents.

In a surplus situation, the best option is to export the digestate obtained following anaerobic digestion. If the cost of transportation is not affordable, other alternatives should be considered. Here we explain which ones.

Composting pig manure results in a product that can be sold in the organic amendment, horticulture, and gardening market.

Among other things, anaerobic digestion improves the fertilizer quality of slurry and reduces odors and GHG emissions. The choice to use this or not will also depend on the justification of the cost, i.e. whether it allows for energy savings on the farm or whether it provides an income from the sale of the energy generated.

In addition to the environmental benefits, the increased cost of energy and inorganic fertilizers make on-farm biogas production an interesting cost-effective option.

Solid/liquid slurry separation systems improve the subsequent management of the slurry, such as its transport or further treatment of each fraction.

Acidification of slurry prevents the formation of ammonia and its loss by volatilization, reducing the loss of fertilizer value of the slurry.

In a situation with a nutrient surplus, the cost of transport is often the most important limiting factor to consider when deciding on the best manure management system for the farm.

Do you know the most effective, practically applicable, and economically feasible measures to reduce ammonia emissions? Proper application of these measures would meet the requirements set forth in the regulations.

In a situation of nutrient balance between the nutrients produced and the needs of the crops, priority is given to the transport and application management and the fertilizer quality of the slurry. Which systems allow me to optimize these?
