You do not need the engineering to read the impact. This is the whole machine in four lines.
The material is heated in a low oxygen chamber. With almost no oxygen it cannot burn, it breaks apart.
The solid turns into a combustible gas, and a solid residue is left behind. Two outputs, one input.
The gas passes through a cleaning stage intended to remove tars and contaminants.
The gas could become electricity and heat. The solid residue would be tested per batch before any land destination is considered.
The one technical difference, in plain words. Jenja can be supplied with a drying unit, which is the first step of the process: the fuel is dried before it is gasified, and ready-made dry pellets do not need this step. Moisture is a cost to manage rather than a barrier. That is why the feedstock can be the residue a site already has, instead of clean, expensive, sorted fuel.

Burning destroys. Heating without oxygen separates, and separation lets you keep every part.
Electricity and heat, in air blown operation. Built for the waste a site actually has.
Hydrogen and liquid fuels, drawn off the gas stream. A separate mode with separate chemistry, run only for fuel production, and never at the same time as power generation.
Why the mode separation matters here. The chemistry, the emissions and the numbers are different between the two modes, so figures from one never appear as evidence for the other. That rule is enforced on this site rather than left to the reader.
