As Greening’s dedicated biomethane platform, we integrate project development, engineering, permitting, feedstock origination, and project structuring to accelerate renewable gas production and create lasting value for local communities.
We develop integrated biomethane projects that transform organic resources into sustainable energy infrastructure, driving decarbonisation, the circular economy, and Spain’s energy independence.
TraWe transform waste into renewable energy.
ABOUT US
A Platform Driving the Future of Biomethane
Twine is Greening’s specialised platform for the end-to-end development of biomethane projects in Spain. We were created with a clear purpose: to transform agricultural, livestock, and organic waste into renewable energy that accelerates the transition towards a cleaner, more circular, and energy-independent future.
From project conception through to Ready-to-Build (RTB) status, we combine technical expertise, industrial vision, and a strategy built around the efficient use of local resources. Our integrated model covers every critical stage of development, turning opportunities into robust, scalable projects designed to deliver long-term impact.
OUR ACTIVITY
Integrated Development That Turns Opportunities into Projects
At Twine, we manage every stage of project development to deliver viable, efficient assets that are ready for construction and operation.
Integrated Development
We oversee the entire project lifecycle, from identifying opportunities through to achieving Ready-to-Build (RTB) status, maintaining full technical, regulatory, and strategic control at every stage.
Project Development
Our in-house development model integrates feedstock origination, site selection, permitting, engineering, gas grid connection, and project structuring to maximise project quality and efficiency.
Collaborative Model
We work alongside farmers, livestock producers, waste management companies, landowners, public authorities, industrial partners, and investors to develop sustainable projects that create shared value and long-term benefits.
OUR IMPACT
A Portfolio Ready to Lead Biomethane Development in Spain
Our growth reflects a strategy focused on high-quality project development, proximity to local resources, and the creation of an industrial platform with a long-term vision.

BIOMETHANE IN SPAIN
A Strategic Opportunity to Transform the Energy System
Biomethane has emerged as one of the key technologies driving the transition towards a more sustainable energy system. Europe is accelerating the deployment of renewable gases through an ambitious regulatory framework, while Spain offers the ideal conditions to become one of the continent’s leading biomethane producers.
Its abundant agricultural and organic waste resources, well-established gas infrastructure, and significant technical potential position Spain at the forefront of the renewable gas transition.
At Twine, we develop the projects that will turn this potential into reality.
OUR VALUE
Renewable Energy with Real Impact
Decarbonisation
We reduce CO₂ emissions by replacing fossil fuels with renewable gas produced from locally available organic resources.
Circular Economy
We recover value from agricultural, livestock, and organic waste by transforming it into renewable energy and closing the organic resource loop.
Rural Development
We stimulate investment, skilled employment, and new economic opportunities in regions with strong agricultural potential.
Collaboration
We build long-term partnerships with producers, public authorities, businesses, and local communities to create projects that generate shared value.
Energy Security
We strengthen energy independence through the local production of renewable gas that is fully compatible with the existing gas infrastructure.
