Althenia, solutions for decarbonization and CO2 neutralization

In a world where Decarbonization is key to achieving net zero emissions by 2050, Althenia Sando emerges as a leader, offering effective solutions to the complexity of this global challenge. To remove 8 billion tons of CO2 per year from the atmosphere by 2050, according to the Intergovernmental Panel on Climate Change (IPCC).

As a company specialized in environmental actions, Althenia Sando develops projects and innovative solutions in the neutralization and capture of CO2. We recognize that simply reducing emissions is not enough; and we must capture the excess Greenhouse Gases (GHG) we already have in the atmosphere to mitigate the effects of climate change. This is urgent.

Undoubtedly, the main source of CO2 absorption on the planet are natural sinks, forests, urban trees, soils and oceans. We are specialists in the first three and are committed to data models that ensure the care, microbiodiversity and proper use of water resources. We complement our value proposition with technological innovation. We consider important the solutions oriented to industrial CO2 capture, with techniques such as DAC (Direct Air Capture), Carbon Mineralization, BECCS (Bioenergy), Pyrolysis (Thermal Process), CCUS (Capture, Use and Storage of CO2), and development of circular economy such as biogas energy generation from biomass, and development of new asphalt and cement products based on captured CO2.

Althenia Sando offers key support to public and private organizations to effectively integrate environmental Sustainability criteria in their operations and throughout their value chain.

In this way, it contributes to the assumption of an active role by the different organizations in the current context of “climate emergency”, with serious environmental impacts that also have repercussions on the socioeconomic dimension at a global level.

Trees as carbon sinks

Althenia Sando offers tree and forest management solutions, ranging from the reforestation of degraded areas, overexploited or affected by fires, to the creation of forest mass by planting trees in soils previously devoid of forest, using the appropriate species in each ecosystem. These forests and woodlands, together with the soil and the oceans, act as natural carbon sinks by absorbing atmospheric CO2. According to data from the World Economic Forum, a single tree is capable of absorbing around one ton of CO2 over its lifetime, and the average European emits between five and seven tons of CO2 per year, highlighting the magnitude of our impact. Therefore, at the citizen level, five to seven trees should be planted each year to offset each other’s emissions. Through our forest management and urban tree planting solutions, Althenia Sando actively drives decarbonization, thus contributing to mitigating the effects of climate change. We don’t just plant trees; we create effective carbon sinks. In addition, each hectare of forest we transform absorbs approximately 100 tons of CO 2 reinforcing our dedication to environmental sustainability and the fight against the global ‘climate emergency’.”

Tree stands for the production of forest biomass

Althenia Sando plays an integral role in the installation of tree stands with the objective of taking advantage of the Waste generated to obtain biomass, a renewable energy source after a specialized treatment process. This energy transformation is materialized from various resources, such as forest residues, by-products resulting from the transformation of wood, the organic fraction of urban or industrial waste, as well as the organic portion present in sewage or industrial sludge. The diversification of these sources ensures a solid base for biomass generation, strengthening Althenia Sando’s commitment to sustainability. Althenia Sando’s specialized service in the planting of tree stands for the production of forest biomass not only guarantees the constant availability of this resource, but also contributes significantly to soil fixation, prevents soil erosion, provides nutrients and generates microbiodiversity, while helping to consolidate essential materials for future renewable energy applications. This proactive approach reflects Althenia Sando’s ongoing commitment to promoting sustainable energy solutions and underscores its position as a leader in promoting environmentally friendly practices.

Biogas energy generation from biomass

Biogas energy production from biomass is an important focus of Althenia Sando’s waste treatment services. We carry out innovative projects that transform biomass into biogas, using both thermochemical and biological processes, highlighting anaerobic biodigestion. The latter process involves the conversion of gases generated during the decomposition of organic materials into a valuable source of energy. The implementation of these advanced technologies reflects Althenia Sando’s commitment to sustainable and efficient waste management solutions, thus contributing to the transition towards cleaner and renewable energy sources.

Compromiso con la sociedad

While we recognize the challenges, our commitment to society is strengthened. Althenia Sando embarks on CO2 neutralization on a climate-significant scale, merging technology and innovation with a deep respect for nature. In addition, our commitment is supported by research and innovation projects, offering services of the highest quality in our mission to actively contribute to a sustainable future.
