BIOGAS TECHNOLOGY

What is biogas technology

Biogas technology is an example of circular economy applied to renewable energy production. The process is based on anaerobic digestion, a biological reaction that takes place in the absence of oxygen and transforms the organic content of biomass into biogas. This technology for biogas production is therefore based on biological processes for the recovery of waste materials and the production of renewable energy.

Each plant starts from an in-depth analysis of the available biomass: we carry out a preliminary mass balance to identify the most suitable biogas technology for each specific case.

Our technological solutions vary according to:

• Dry substance and organic content
• Temperature regime (mesophilic, thermophilic, psychrophilic)
• Hydraulic retention time
• Mixing system

How the biogas technology process works

We design plants for the treatment and valorization of biomass from the agricultural, industrial, waste, and sludge sectors, integrating different technologies to optimize anaerobic digestion and biogas production.

The process begins with biomass pretreatment. The biomass is then fed into the digesters through a pre-tank or feeding system. Anaerobic digestion takes place in digesters fitted with gasholder covers, which collect and store the biogas produced.

Use of digestate produced by biogas technology

In addition to energy, the biogas technology process produces digestate, an effluent that can be valorized.

The digestate leaving the process has a dual agronomic value, as it enriches the soil with mineral elements and contributes to carbon storage in soils.

In addition, digestate can be separated into liquid and solid fractions and, if necessary, subjected to post-treatment processes to improve its soil-improving and fertilizing capacity, or to reduce the presence of nitrogen and other pollutants.

The latest European regulations on RENURE (REcovered Nitrogen from manURE) recognize the value of nitrogen recovered from livestock manure, encouraging its use as an alternative to synthetic fertilizers.

Feeding the biogas plant

Thanks to our experience and a portfolio of more than 70 different biomasses analyzed, we are able to develop tailor-made recipes to treat heterogeneous and complex biomass through anaerobic digestion.

Our approach combines accurate analysis, flexibility, and biological know-how:

• we assess the characteristics of the feedstocks
• we design the most suitable technology
• we ensure maximum efficiency through our biological and process services

Environmental and economic advantages of biogas technology

Building and installing a biogas plant means making your company more sustainable, efficient, and competitive.

The main benefits include:

• Energy independence, thanks to self-produced electricity and heat
• Clean energy for the community, contributing to a sustainable energy policy
• Valorization of company waste and effluents, turning them into resources

With our biogas plants, waste becomes an opportunity, your company becomes a key player in the fight against climate change, and your business becomes a circular economy model.
