According to Fortune Business Insights, the global biomethane market size was valued at USD 6.95 billion in 2025 and is projected to grow from USD 7.28 billion in 2026 to USD 10.74 billion by 2034, registering a CAGR of 4.97% during the forecast period. Biomethane, also known as Renewable Natural Gas (RNG), is a purified form of biogas produced from organic materials such as agricultural waste, sewage sludge, domestic waste, and other biodegradable feedstocks. Its applications across power generation, heating, cooking, and transportation are supporting market expansion.

Growing Adoption of Biomethane as Renewable Energy

The increasing focus on renewable energy and reducing dependence on conventional fossil fuels is supporting the growth of the biomethane market. Biomethane can be produced from waste materials while simultaneously supporting energy recovery and waste-management objectives. Its potential to reduce greenhouse gas emissions compared with conventional fuel alternatives is also increasing its attractiveness among energy producers and end users.

Governments and energy companies are increasingly investing in renewable natural gas infrastructure, including production facilities, upgrading systems, and distribution networks. These developments are expected to create new opportunities for biomethane producers and technology providers.

Conversion of Waste into Energy Drives Market Growth

The conversion of organic waste into usable energy is one of the major factors driving the biomethane market. Agricultural residues, food waste, municipal waste, sewage waste, and other organic materials can serve as feedstocks for biomethane production.

The availability of diverse feedstock sources provides producers with greater flexibility while helping address waste-disposal challenges. The organic residue & wastes segment is projected to account for 73% of the market in 2026, supported by the broad availability of these raw materials.

Technological Advancements in Anaerobic Digestion

Technological developments in anaerobic digestion are contributing to improvements in biomethane production efficiency. Enhanced reactor configurations, process optimization, improved microbial cultures, and continuous anaerobic digestion systems are helping increase biogas yields and operational stability.

Advanced membrane technologies are also being used to purify biomethane to pipeline-quality standards. In addition, pressure swing adsorption (PSA) systems provide flexible options for upgrading biogas. Mechanical, thermal, and enzymatic pretreatment technologies can further improve feedstock digestibility and methane production.

These advancements are expected to reduce production costs, improve efficiency, and support the wider adoption of biomethane technologies.

Rising Demand from the Automotive Industry

The transportation sector represents an important opportunity for biomethane market growth. Upgraded biogas can be used as a transportation fuel and as an alternative to conventional natural gas-based fuels.

The availability of agricultural waste, food waste, and industrial waste provides a growing source of raw materials for renewable natural gas production. The increasing focus on reducing transportation-related emissions is also encouraging the development of renewable fuels.

As more countries develop renewable fuel infrastructure and support cleaner transportation solutions, demand for biomethane-powered vehicles and related fueling infrastructure could increase over the forecast period.
