TacklEmission is an undergraduate research initiative developing targeted, biodegradable nanotechnology that reduces methane-producing microbes in the cattle rumen, helping agriculture move toward net zero.

Livestock agriculture accounts for roughly 14.5% of global greenhouse gas emissions, and enteric fermentation is the biggest contributor. Methane traps about 28 times more heat than CO₂ over a 100-year period, and with 1.5 billion cattle worldwide producing close to 100 million tonnes of it every year, the scale of the problem is enormous.

Our platform, PHA-PeiR, works by anchoring the PeiR pseudomurein endoisopeptidase enzyme onto biodegradable PHA (polyhydroxyalkanoate) nanoparticles that are delivered through ordinary cattle feed. PeiR breaks down pseudomurein, a cell wall component found only in methane-producing archaea. That gives it pinpoint selectivity. It doesn't touch the beneficial bacteria in the rumen or affect animal health, and farmers don't need to change their existing setup to use it.

We're aiming for a 60 to 80% reduction in methane per animal, all while keeping the rumen's microbial balance intact so cattle stay healthy and productive.
