Roblum is the first green biomass power plant with a negative carbon footprint, capable of generating energy for the needs of around 50,000 households.


Roblum is a biomass plant, a renewable energy source from the controlled combustion of organic waste from agriculture. These residues amount to millions of tonnes, part of which are not used nowadays.

The benefits of Roblum

Encourages field cleanliness
Improves their phytosanitary condition
Minimises the risk of fires that are difficult to control
Reduces the use of agrochemicals and nitrogen fertilisers
Valorises unused maize straw, rye straw unsuitable for livestock feed and rapeseed straw
It will also provide additional income for local farmers, some 16 million euros per year including logistics, as well as the creation of stable, high-quality employment in rural areas, the typical biomass location.

Some key features

Negative carbon balance

Roblum achieves a negative carbon balance from biomass because the CO₂ fixed by the biomass compensates the carbon produced in the facilities and, moreover, this is captured and stored for use in the generation of green e-methanol by La Robla Nueva Energía.

Manageable electricity generation

With the manageable production of the facilities through some 290,000 tonnes of biomass, the area’s electricity system will be provided with greater stability.
