Biogas

Biogas differs from solar and wind because its availability depends on continuous flows of digestible organic feedstock, collection, transport, sorting and stable digester operation. A large theoretical waste resource therefore does not by itself demonstrate implementable or operating energy capacity.

This page uses Biogas mainly for gas produced by anaerobic digestion of organic material. Biomass is a broader category and not all biomass is suitable for digestion. Landfill Gas is generated and collected from landfills and is treated as a distinct technical pathway. Biomethane is upgraded biogas after removal of carbon dioxide and impurities; the sources reviewed through 13 August 2026 did not provide a verified national record of commercial biomethane production in Syria.

We also separate direct gas use for heat or cooking from electricity generation in an engine or generator. A defensible national figure for operational biogas-fired electrical capacity is not currently available, so this page does not manufacture an estimate to fill that gap.

The strongest historically documented Syrian pathway is livestock manure, particularly cattle manure at farms or clusters where collection can be regular. Poultry waste can also be relevant, but nitrogen concentration, moisture and handling require appropriate design and operation; a current national dataset for collectable and digestible poultry waste was not identified.

Wastewater-treatment plants and sludge can offer concentrated feedstock streams for anaerobic digestion, while the organic fraction of municipal waste depends heavily on sorting and contamination control. Agricultural and agro-industrial residues are not uniformly digestible; some are better suited to other bioenergy pathways.

We distinguish four layers: theoretical potential → technical potential → practically collectable feedstock → economically viable potential. Each step reduces the usable resource through technical, seasonal, logistical, distance, contamination and operating-cost constraints. The 379 million tonnes and 4.6 billion m³ figures are therefore not converted into MW without a project model, conversion factors and explicit system boundaries.

Historical — 1990: a scientific review records a 100 m³ digester implemented at a cattle farm by the Ministry of Agriculture. It is retained as a historical record only; continued operation is not assumed.

Historical — 2008: the review records 19 household digesters of 13–20 m³ implemented by the National Energy Research Center. These are historical household units, not national electrical capacity.

Historical — 2018: the review records 120 household digesters in northern Syria and attributes implementation to FAO and community actors. No public registry was found that establishes the 2026 operating status of every unit, so they are not added to a current operating total.

Historical — 2021: the review records 42 implemented digesters, split between 34 smaller units and eight larger units. This is treated as a reference-year record, not necessarily a cumulative total of all earlier digesters.

Pilot / Demonstration — 3 April 2024: ACSAD and Damascus University officially reported opening a biogas digester project at the Faculty of Agriculture to convert organic waste into energy and organic fertilizer. The opening is documented, but the source does not publish electrical capacity, annual gas output or continuous operating status.

Historical / Demonstration — Qatra al-Rihan village, Al-Ghab, Hama: the same ACSAD source reports a village biogas digester implemented with the Ministry of Agriculture under a rural-development initiative. It does not provide electrical capacity, annual gas production or current operating evidence.

Limited biogas deployment in Syria does not necessarily mean the resource is absent. The harder problem is converting dispersed and sometimes seasonal material into a dependable supply chain: collection, storage, mixture and moisture control, digester operation, gas treatment, engine or burner maintenance and digestate management.

Project economics are rarely about electricity sales alone. At small and medium scale, value can come from waste treatment, local fuel or heat substitution, avoided disposal costs and use of digestate as an agricultural product where health and agronomic requirements are met. A continuous heat demand can materially change project economics compared with electricity-only operation.

For this reason, on-site use at a farm, food-processing facility or treatment plant may often be more logical than a small grid-export-only project. The decision still requires project-specific analysis of year-round feedstock, collection distance, gas quality, operating hours, heat or power demand, grid connection, spare parts and operating capability.

Biogas is not described here as “zero emission.” A defensible assessment needs clear lifecycle boundaries and must consider methane that would otherwise escape from waste, fugitive methane from the digester or gas system, displaced fossil fuel, feedstock transport and digestate management.

CO₂, CH₄ and CO₂e must remain distinct. Because Syrian facility-level data on leakage, capture efficiency, transport and final use are not available as a national dataset, this page does not publish a single national emission factor. Serious climate comparison requires a project-specific lifecycle assessment and a baseline describing what would happen to the waste without the project.

The official 2025 procedural guide defines renewable energy to include bioenergy and applies the full-output-sale procedure to investors connecting renewable electricity projects to the grid and selling all generated electricity.

The simplified pathway is: project application → grid-connection point and initial approval → agreement → implementation → electrical connection → licence and commercial operation. The 12-month period specified for 2–10 MW solar projects is not applied to biogas; the guide states that implementation periods for other types are agreed according to the nature of each project.

This pathway concerns electricity generation, connection and sale. Waste-treatment, wastewater or digestion facilities may also require environmental, municipal or health approvals depending on site and feedstock, but this page does not invent those requirements without case-specific legal sources.

Last updated: 13 August 2026. Biogas means gas from anaerobic digestion, while Biomass, Landfill Gas and Biomethane are kept distinct. Installed/Nominal Capacity is also separated from Operational Capacity, Actual Generation and Planned/Announced Capacity.

The page uses Syria-specific scientific studies, primary institutional project sources such as ACSAD, and the Ministry of Energy's official procedural guide. The older Syrian Renewables page was used as a research lead and historical baseline, but its figures were not automatically carried forward without a traceable source.

The main data gap is the absence of a current public national registry showing, for every digester, location, feedstock, digester volume, gas production, gas use, electrical or thermal capacity and operating status. Older units are therefore classified as Historical where current operating evidence is absent, and records from different years are not added as if they were a cumulative census.

Bioenergy is not used as a synonym for Biogas, and the 379 million tonnes of biomass or 4.6 billion m³ theoretical potential are not converted into MW or MWh. Any future energy estimate should disclose the equation, inputs, methane share, heating value, efficiency, operating hours, losses and low/reference/high scenarios.
