Last year, Sebigas surprised visitors with a booth entirely made of cardboard, an original and sustainable project that tangibly represented our core values: circularity, reuse, and environmental responsibility. A symbolic yet concrete gesture that underlines how sustainability is an integral part of the way we design and build every plant.

This year, we are ready to surprise you once again, with new projects to share. Over the past year, Sebigas technology has been chosen for numerous revamping projects of existing plants, as well as for new constructions across several South American countries, where interest in renewable and sustainable energy solutions continues to grow.

This is a result that confirms the trust of our partners in the solidity, efficiency, and flexibility of Sebigas solutions, systems capable of valorizing any type of feedstock and adapting to a wide range of production and territorial contexts.

SEBIGAS started the construction for the revamping of an existing 1 MW biogas plant into a facility producing 500 Smc/h of biomethane. The plant’s feedstock will consist of approximately 78,000 tons per year of biomass, including pig slurry, poultry manure, olive pomace, and silage.

The project involves a complete reconfiguration of the plant, including the construction of four new tanks measuring 28×8 meters: one storage tank for olive pomace, a primary digester, and two final tanks equipped with biogas recovery systems, in line with the guidelines outlined in the 2022 Biomethane Ministerial Decree.

With this project marking its fifth reference in the field of plant revamping, SEBIGAS further strengthens its position as a strategic partner in the biomethane sector.

The company reaffirms its role as a reliable point of reference, thanks to its ability to deliver comprehensive and customized solutions, both as a technology provider and through specialized engineering services.

This achievement reflects the market’s growing trust in SEBIGAS’ technical expertise and sustainable vision, actively contributing to the development of a more efficient and innovative energy sector.

What is a biomethane plant?

Biomethane plants are a sustainable and profitable solution for renewable energy production. Biomethane is a gas obtained 100% from renewable sources through a purification process (upgrading) of biogas, which is generated via the anaerobic digestion of organic matter.

The biomass used to feed biomethane plants contains a high amount of organic material degradable by anaerobic bacteria.

In biomethane plants, raw biogas undergoes an upgrading treatment, which involves the removal of impurities and the separation of methane from all other components. The goal is to achieve a minimum CH₄ concentration of 95% and to meet the required quality standards.

The most commonly used biogas purification technologies in biomethane plants include:

• • • Membrane technology;
    • Water scrubbing;
    • Chemical absorption;
    • PSA (Pressure Swing Adsorption).

Biomethane plants: risks and pollution

Biomethane plants do not contribute to greenhouse gas emissions or air pollution. Instead, anaerobic digestion prevents the disposal of biomass in landfills, where its natural decomposition would generate greenhouse gas emissions.

The plants are designed to minimize odor production, but their management depends on several factors, including:

• • • The type of biomass used;
    • Storage and transport methods;
    • Implemented odor control technologies.

To mitigate potential odor emissions, solutions such as covers for pre-tanks and final tanks, as well as anti-emission covers for slurry storage tanks, are used. These measures reduce gas emissions and prevent their dispersion into the atmosphere caused by wind.

Biomethane plants in Europe: overview and growth

Biomethane plants in Europe are experiencing rapid growth, driven by the EU’s push for decarbonization and energy independence. With strong policy support under the Renewable Energy Directive (RED II) and national incentive schemes, the number of operational plants has steadily increased across member states.

In 2024, Europe boasts 1.548 biomethane production facilities, marking a significant increase from previous years. According to the European Biogas Association (EBA), combined biogas and biomethane production by the end of 2024 has reached 6.4 bcm/year.

Authorization for biomethane plants: regulations and requirements

The authorization process for biomethane plants in Europe varies Country by Country but generally involves compliance with EU environmental and energy regulations, including permitting for emissions, land use, and safety standards. Developers must obtain several approvals, such as environmental impact assessments, building permits, and grid connection agreements. In many EU countries, streamlined procedures have been implemented to simplify and accelerate the permitting process. Additionally, access to financial incentives often requires compliance with national renewable energy targets and sustainability criteria.

How much does a biomethane plant cost?

To determine the cost of a biomethane plant, an accurate project assessment is essential, considering various technical factors. The cost depends on the plant size, the type of biomass used, the upgrading technology, and the connection works to the national gas grid. Only through a detailed study and an economic-financial analysis of the project is it possible to accurately determine the investment value and its financial sustainability.

Generally, the cost of a greenfield biomethane plant between 200 and 500 smc ranges from €8 to €15 million, including civil works, upgrading system, and grid connection.

Biogas vs biomethane: what are the differences?

Milan, 26 February 2025 – Sebigas, an Italian company specialized in the design and construction of biogas and biomethane plants, has been selected by Genera4—a Chilean company with over 15 years of experience in the sector—for the development of two new plants: Los Laureles and Los Ciruelos. This collaboration represents a milestone in Sebigas’ international growth strategy, further strengthening its presence in the South American market, as well as a transformative contribution to Chile’s biogas and biomethane sector, which currently features only one operational biomethane plant in Santiago. Currently, all natural gas consumed in Chile is imported as LNG through the port of Quintero and distributed via pipelines or road transport.

Federico Torretta, General Manager of Sebigas, commented: “The Chilean biogas and biomethane market is in its early stages but presents significant opportunities for the advancement of renewable energy. We are proud to contribute our engineering expertise to projects that promote sustainability and energy self-sufficiency.”

The Projects

Los Ciruelos: Located in San Clemente, in the Maule region, this plant is a significant innovation as the first in the country to produce compressed BioCNG. It is designed to meet local demand while contributing to the national energy diversification strategy. The plant will produce approximately 450 Sm³/h of biomethane, processing around 90,000 tons of biomass annually, including poultry litter, fruit and vegetable waste, organic waste, sludge, process water, and olive production residues. The facility features three digesters and a secondary digester. The biomethane produced will be sold to a natural gas distributor and used to replace natural gas in industries and among consumers located within a 200 km radius of the plant.

Los Laureles: Situated in Osorno, in the Los Lagos region, this 3 MW biogas plant will process approximately 64,000 tons of biomass annually, including slaughterhouse waste, sewage sludge, salmon waste, fruit and vegetable waste, and residues from cleaning livestock pens and markets. The facility includes two digesters and a post-digester. The electricity generated will supply a nearby slaughterhouse, with any surplus fed into the electrical grid. Thermal energy, in the form of hot water, will replace LPG usage in the slaughterhouse’s operations.

Both projects have undergone stringent environmental and social approval processes to ensure no adverse impacts on the community. These plants contribute to Chile’s sustainable growth by promoting renewable energy adoption, reducing dependence on fossil fuel imports, and strengthening Sebigas’ presence in the South American market.

The selection of Sebigas by Genera4 — a client with extensive experience in plant design and a deep understanding of technology and operations— highlights the quality and value of the technological solutions offered by the company based in Italy
