There is a certain elegance to the idea of turning a cow's burp into jet fuel. It is a neat, closed-loop solution to a famously messy problem. PLANET.TECH is betting on that elegance. The company is developing a wearable collar for cattle that captures methane emissions at the source, then processes the captured gas into renewable natural gas and sustainable aviation fuel at the milking station [planet.tech, retrieved 2024].
The company claims its system can generate over $800 in new annual revenue per cow, a figure that includes sales of the processed gas and various environmental credits [PLANET.TECH, retrieved 2024]. That is an ambitious figure, given the technical and logistical hurdles of capturing a diffuse, biologically produced gas from a mobile animal.
The methane capture wedge
The core of PLANET.TECH's bet is a hardware wedge: a collar that fits on a dairy cow. The company says its field trials have achieved a 28.8% capture efficiency for enteric methane [PLANET.TECH, retrieved 2024]. If they can maintain or improve that rate at scale, the revenue math starts to work. The captured methane is extracted when the cow visits the milking station, then upgraded to pipeline-quality renewable natural gas. The business model is built on layering revenue streams:
- Gas sales. Selling the upgraded biomethane into the natural gas grid or for vehicle fuel.
- Carbon credits. Monetizing the avoided methane emissions in voluntary carbon markets.
- Policy credits. Capturing value from government programs like Renewable Identification Numbers (RINs) and California's Low Carbon Fuel Standard (LCFS) credits [planet.tech, retrieved 2024].
An early and crowded field
PLANET.TECH is not alone in chasing agricultural methane. The competitive landscape includes companies like ZELP, which also makes a wearable device for cattle to neutralize methane, and Alga Biosciences, which is developing a feed additive to reduce emissions from within the cow's gut [zelp.co, retrieved 2026]. PLANET.TECH is firmly in the capture-and-utilize camp, which offers the potential for a tangible energy product instead of just an avoided emission.
The company's public footprint is currently light, with no disclosed funding rounds or named team on its site. The bold claims of a 14% potential reduction in global methane emissions at full deployment are a vision statement, not a traction metric [PLANET.TECH, retrieved 2024].
The path forward is a steep climb of hardware iteration, farm pilot agreements, and proving that the $800-per-cow promise holds outside a controlled trial. The real test is whether PLANET.TECH's collar can do it reliably, without stressing the animal or complicating farm operations, for a cost that leaves a healthy margin after all that gas and credit revenue is counted.
