Transforming organic waste into renewable energy for a sustainable future
We develop, build, and operate biomethane plants across Spain, turning agro-industrial waste into 100% renewable gas.
News
Our Model
Integrated Biomethane Solutions
We develop end-to-end biomethane projects that transform organic waste into renewable energy. Our integrated approach covers every phase of project development, from initial feasibility studies to long-term operational management.
01
Development
Feasibility studies, permitting, and design for every plant.
02
Construction
Engineering and commissioning of the infrastructure.
03
Operation
Long-term plant management and maintenance.
From Challenge to Opportunity
We turn an environmental challenge into an energy asset.
01
The Challenge
Organic waste from agricultural and industrial operations creates environmental and economic challenges. Improper disposal pollutes soil and water, while valuable energy potential remains untapped.
02
The Solution
Our integrated biomethane system converts organic waste into clean, renewable energy through anaerobic digestion. This proven process generates biogas that we refine into premium biomethane for commercial use.
1
Waste
Organic waste collection
Waste is collected and transported efficiently.
2
Biogas Production
Anaerobic digestion
Waste is transformed into biogas through biological processes.
3
Biomethane Production
Upgrading to biomethane
Biogas is purified for grid injection or vehicle use.
4
End Users
Sustainable consumption
Biomethane is used as clean energy across every sector.
Digestate
A by-product used as a circular organic fertilizer.
Impact and Territory
Creating Sustainable Value
Our projects deliver measurable positive environmental impact while forging robust economic opportunities for the primary sector and rural communities across Spain. We are committed to a sustainable energy development model that simultaneously benefits people, the local economy, and the balance of the planet.
- Measurable environmental impact
- Rural economic opportunity
- Sustainable energy model
