The working collective units and processing methods at the European level have been inventoried by country and by process.

What can we do to face the challenges in the industry? Innovate, research, and bring science closer to the field.

Eight years ago, Granja Capdevila Torrent Ramaders started up its biogas production plant using co-digestion and is now an example of economic viability and sustainability.

We went to visit Piggly, a sustainable farm from an environmental, production, animal welfare, and economic perspective.

Using solar energy to evaporate part of the water from the slurry can be of interest, avoiding volatization of ammonia. Solar drying can be combined with other strategies.

Removing nitrogen from slurry by transforming it into N₂ can be done biologically or by physical-chemical methods, the latter of which are in the experimental phase for slurry.

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.

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?

The complexity of our situation and the objectives to achieve will depend on the results of the nutrient balance. Where do I stand? We'll help you answer this question.

Fertilization is the most direct and simplest way to give value to our slurry. Here we explain several points to take into account for proper fertilization of your soils and crops.

Reducing slurry at the source means modifying production guidelines to reduce environmental effects and improve the subsequent management of slurry.

The slurry that my farm produces is becoming a problem. How can I get the most value from it? How do I make the most of this resource? This step-by-step guide will help you decide which way is best suited to your situation and will allow you to transform what is perceived as a problem into an opportunity.
