There have been studies of manure reactors here in Norway as well, including some really small-scale ones, like the Telemark reactor.

As long as they have animals, getting the manure through the reactor will

• capture methane for use as biogas rather than letting it straight into the atmosphere,
• let that biogas supplant fossil gas ("natural" gas), i.e. rather than free stored carbon it has gone in a loop
• reduce the viability of weeds in the manure, and
• increase the nitrogen availability in the manure, bringing it closer to fossil gas-derived artificial fertilizer in potency.

Biogas reactors are a serious harm reduction win in modern agriculture and reduces reliance on fossil fuels in several ways.

Here it seems like Vox is just peddling "big oil and big ag are in favor, therefore it's sus". Blind hens like those two also sometimes find corn.
