What is ZELP?

About us


ZELP’s mission is to foment the consumption of reduced methane livestock products and to promote research and development in the field. The project is led by Argentinian brothers Francisco and Patricio Norris.


So far we have collaborated with farmers in Argentina and the UK, scientists at Imperial College, Royal Veterinary College and Royal Agricultural University, as well as policy advisers at Argentina’s experimental agricultural associations INTA, and CREA.


We created our own patented technology in the form of a nose ring to drastically reduce the impact of livestock’s methane belch emissions. Our device can help reduce the environmental impact of the methane emissions by a factor of 85 (GWP 20 years).

We are also working on a certification platform to guarantee the ZELP standards are adopted.

How does it work?


We partner with all stakeholders of the value chain: producers, feedlots, slaughterhouses, wholesalers, and retailers to adopt ZELP standards.


We certify the traceability of meat and dairy from inception to end product, and ensure that producers and feedlots employ our technologies to neutralise livestock’s methane emissions. Our certification comes in the form of a quality stamp present in all ZELP certified products.


The willingness to pay extra by the end user increases margins on a pro-rata basis to all stake holders of the value chain. This allows ZELP’s certified products to be sold in retailers at slightly higher prices.

The problem we solve

There are 1.5 billion cows in the world, and they are huge contributors to global warming. Methane emissions from cows belching represent the carbon equivalent of the whole of the transport industry put together.

The Food and Agriculture Organization (FAO) predicts the demand for livestock products to rise by 70% by the year 2050.

Due to the way it traps heat, methane is 85 times worse for global warming than carbon dioxide.
