Sigh...
Here is an OLD study. (Again).
Please read from page 36
https://wteinternational.com/wp-content/uploads/2018/01/Gasification-vs-Incineration.pdf
As gasification technology matures and when electricity prices increase, gasification beats incineration on every metric.
Also, more efficient, half the NOx per gram of waste, more complete combustion, less ash, less hazardous waste, ability to produce biofuels.
If eqtec sites are built on shovel ready sites, the costs come spiraling down. I think the France MDC is going to astonish us how profitable it will be. I am guessing an IRR above 30%. It is forecast to be 78% efficient.
Agricultural biochar is only possible from clean sources of biomass (preferably solids I believe)
Plastic can produce a carbon char but it will be too pulled for agricultural use. Anything nasty (rose cuttings?! Really!!!) Contaminated plastics, tyres, you don't gasify it in the absence of oxygen to produce buochar, you gasify it fully to reduce the ash content to below 5%.
It's a relationship between the product in and the products out. Clean agro waste with low impurities can be turned into biochar and heat and power. When power prices are up the plant can be changed into high power mode and therefor no biochar comes out.
