More and more slurry is being produced and legislation is becoming more restrictive.

The livestock sector faces the challenge of what to do with its effluents. To comply with the new legislation that prohibits direct application of slurry on fields, processes must be employed that entail increased management costs. Proper slurry management begins with a biogas plant.

WASTE MANAGEMENT .

The circular economy and valorisation of organic waste pose a challenge to contemporary society. The new regulations require full valorisation and traceability of waste until the final treatment.

The entire value chain is responsible for mitigating or preventing the impact of waste-generating processes on the environment and has a legal duty to manage them properly. Converting waste into a new resource is the best way to achieve this.

The problem: what to do with slurry?

The livestock sector faces the challenge of what to do with its effluents and how to adapt its production system to the currently applicable legislation (the new European framework is tougher the Spanish regulations).

Slurry, regardless of its origin (swine, cattle, sheep, goats or poultry), contains organic matter that the law prohibits from being discharged directly into watercourses or applied on fields. Building and operating a treatment plant is one option but the cost (approximately one million euros) impedes access to this solution.

Changes in regulations regarding slurry and other agricultural effluents

Royal Decree 980/2017 that amends the Royal Decrees of 2014 (1075/2014, 1076/2014, 1077/2014 and 1078/2014) introduces new regulations for distribution of slurry and effluents from livestock farming. This more restrictive legislation directly affects the livestock sector, which was already experiencing problems dealing with the amount of slurry it produced. This is especially true of pig farming, which generates larger quantities of slurry per head.

The following is an excerpt from Royal Decree 980/2017:

“Slurry may not be applied on agricultural land with using splash plates or cannons…” and “solid manure must be buried immediately following application…”

This means that to avoid atmospheric pollution it is no longer possible to spread slurry using splash-plate fan systems or cannons. The aim of this legislation is to put an end to the direct application of from tanks towed by tractors.

Failure to comply with the new regulations will disqualify farms from receiving subsidies and aid from the Common Agricultural Policy (CAP).

The solution: a biogas plant

In view of the currently applicable regulations and in anticipation of stricter legislation resulting from the transposition of EU law, the production of biogas from waste generated by livestock farming (pigs, cattle, sheep, goats, poultry, etc) provides a sustainable solution to treatment and management of liquid manure.

Biogas generation reduces the environmental impact of agricultural livestock operations in their respective areas and improves their social acceptance.

Advantages

Energy self-sufficiency: off-grid consumers gain access to power supply thanks to the energy generated using their own resources. This will also lead to a real improvement in harnessing renewable resources. Generation of thermal energy (heat) with numerous potential uses on the farm from cooling milk in dairy operations to supply of abundant domestic hot water.

Reduction in the effluent volume and lower management costs of the liquid digestate.

The organic load of the slurry is also reduced by the biological biogas generation process, thus enabling an increase in the legally-applicable quantity per hectare. This means that a higher quantity can be applied to fields near where the slurry is produced, with the consequent fuel and labour savings.

One way of reducing the cost of applying slurry on fields is to reduce the volume produced. By using the thermal energy generated by the biogas plant to evaporate water from the digestate, the latter can be concentrated into a product richer in nutrients and cheaper to transport per unit of fertilizer.

The slurry undergoes “anaerobic composting” during the time it spends in the biogas plant, a process that eliminates a high percentage of pathogens, seeds and other undesirable components present in the prior to fermentation.

A solid, composted by-product with stabilised nutrients (C, N, P, S, K) and higher agronomic value is obtained, a liquid product that – once certified by the authorities – can be classified as an ecologically-friendly organic fertilizer rather than mere slurry.
