Advances in Natural Gas Engine Technology Position RNG as a Practical Path for Heavy-Duty Fleets

A new generation of high-efficiency natural gas engines, paired with rapidly expanding renewable natural gas (RNG) infrastructure, is positioning natural gas as a commercially viable, performance-ready fuel for heavy-duty fleets. As diesel prices surge amid global market volatility, domestic RNG has remained relatively stable, widening the cost gap and reinforcing its value as a cost-control strategy for long-haul freight operators.

Produced from organic waste streams such as landfills, dairy farms and wastewater facilities, RNG is fully compatible with existing pipelines and fueling stations, allowing fleets to adopt it without new infrastructure. Backed by federal incentives like the Section 45Z Clean Fuel Production Credit and state low-carbon fuel programs, RNG supply has grown sharply in recent years, making it an already-available pathway to lower-emission, cost-effective heavy-duty transportation.

Sumitomo do Brasil and Cemvita Partner to Integrate RNG and Bio-Oil Production in Brazil

Sumitomo Corporation do Brasil and biotechnology company Cemvita have announced a partnership to integrate the production of renewable natural gas (RNG) and bio-oil, a precursor of sustainable aviation fuel (SAF), in Brazil. The collaboration pairs Cemvita’s biotechnology platform with Sumitomo’s global infrastructure and market access to convert waste streams into higher-value, lower-carbon fuels and accelerate commercialization in the country.

By integrating bio-oil technology with RNG projects, the partners aim to produce both fuels in parallel, creating operational and economic synergies while supplying waste-based feedstock for sustainable aviation fuel. The companies describe RNG as a strategic global commodity and position Brazil as a critical long-term hub for biofuel supply and the circular bioeconomy.

One of Canada’s First RNG Plants Now Fully Operational in Blenheim, Ontario

One of the first renewable natural gas (RNG) plants in Canada is now fully operational in Blenheim, Ontario. The $100-million facility, built by Waste Connections with support from Enbridge Gas at the Ridge Landfill, captures landfill gas generated by decomposing waste and converts it into carbon-neutral, pipeline-quality RNG. The clean gas is injected into the natural gas distribution system, supplying roughly 18,000 homes and businesses, or about 40 percent of Chatham-Kent.

Project officials say the plant has run smoothly since being commissioned, recently reaching 98 percent uptime. The facility removes oxygen, nitrogen dioxide, carbon dioxide and other compounds before injecting clean gas into the pipeline, and it is expected to offset more than 110,000 tonnes of greenhouse gas emissions per year, supporting Ontario’s 2030 climate goals.

Archaea Energy and Republic Services Celebrate First RNG Plant in Landmark Partnership

Archaea Energy, a subsidiary of bp, and Republic Services have marked the opening of the first renewable natural gas plant under their Lightning Renewables joint venture, which is slated to include roughly 40 RNG projects in total. Located in Fort Wayne, Indiana, the facility captures landfill gas generated by the decomposition of waste at a Republic Services site and converts it into pipeline-quality RNG.

The plant uses a modular, skid-based design that allows for faster construction than traditional custom-built RNG facilities. Once fully operational, it is expected to process up to 6,400 standard cubic feet per minute of gas, enough to heat more than 25,000 homes annually, according to the U.S. EPA, while supporting local air quality and expanding domestic energy production.

Casella Waste Systems and Waga Energy Unveil RNG Facility at Ribbon Cutting

Casella Waste Systems and Waga Energy held a ribbon-cutting ceremony to mark the opening of a renewable natural gas production facility at the Chemung County Landfill in Elmira, New York. The plant has been converting landfill gas into RNG since January 2026 and uses Waga Energy’s patented WAGABOX technology to upgrade the gas to pipeline quality, which is then injected directly into the Valley Energy distribution network.

The facility is designed to generate up to 610,000 MMBtu of renewable gas per year and is expected to avoid more than 47,000 tons of CO2-equivalent emissions annually, according to EPA standards. In its first year, it is projected to produce 340,000 MMBtu, equivalent to roughly 2.4 million gallons of diesel fuel. Casella leaders described the project as a key example of partnering with specialists to create value from waste.

Gasum Sells Lahti Biogas Upgrading Unit to Nevel in Supply Chain Restructure

Finnish gas company Gasum has sold its biogas upgrading unit in Lahti to energy company Nevel, with the transaction taking effect on June 23. Under the arrangement, Nevel takes ownership of the upgrading unit and will manage the full value chain from raw biogas production through upgrading, while Gasum continues to purchase all of the resulting biomethane under a long-term agreement and feeds it into the gas network. The companies said the change will have no impact on customers.

Nevel had previously supplied raw biogas to the unit from its adjacent Kujala plant, which processes around 90,000 tonnes of biodegradable waste, sewage sludge, and industrial side streams each year and produces roughly 50 GWh of biogas. Nevel, which acquired the biogas plant from Labio in 2025, plans to invest in renewing operations to improve efficiency and expand upgrading capacity. Gasum retains ownership of the gas grid connection and associated container unloading station.

Biogas Producer PGB Cuts Ribbon on New Plant in Poland

Polish biogas producer Polska Grupa Biogazowa (PGB), part of TotalEnergies, has launched its 22nd biogas plant in the country. The new installation in Dlugoszyn, in the western Lubusz province, will process about 46,000 tonnes of substrates per year, producing 8.4 GWh of electricity and 8 GWh of heat. The company said the generated electricity will meet the demand of roughly 3,000 households.

The 1 MWe plant is expected to deliver an estimated PLN 4 million (around USD 1 million) in annual benefits to the local community within a 50 km radius, flowing to agri-food and digestate processors as well as transport and service companies. PGB is the largest producer of electricity and heat from biogas in Poland, with a roughly 15% market share, and is developing a network of biogas and biomethane plants that support the circular economy and help stabilize the national power system.

3 Open Minutes with Geoff Dietz

Renewable natural gas (RNG) projects capture methane from animal manure to create a low-carbon, waste-derived fuel to power vehicles and buildings. The latest data shows that U.S. farms are capturing 166% more biogas than what was captured five years ago, processing 25 billion gallons of manure annually. For dairy farmers, these projects are an economically sustainable practice that redirects methane from the environment.

Progressive Dairy Editor Jenn Coyne connected with Geoff Dietz, senior director of federal government affairs with the Renewable Natural Gas Coalition, to learn more about how this alternative energy sector has evolved to its current state in the U.S. dairy industry.

BCG White Paper: The Shock That Reframed Energy Security and the Importance of Biofuels

A new BCG white paper argues that a recent energy supply disruption through the Strait of Hormuz has reframed biofuels from a decarbonization lever into a core energy-security tool. The authors note the corridor is a chokepoint for roughly 20% of global LNG trade, with impacts cascading across oil, LNG, petrochemicals, fertilizers, and transport fuels.

The paper makes the case that biofuels can serve as a practical shock absorber within a broader resilience portfolio, reducing marginal import exposure, creating domestic price anchors, and improving crisis resilience, and suggests this changes how the biofuel premium should be valued.
