I worked in a paper mill for a summer job. The stench is awful. I pity someone that works in a place like that for a living.
Nobody pulps anymore. They do that in Canada and Brazil. The pulp arrives in 500# bales in containers, usually by rail. That hydrogen sulfide smell is a thing of the past, unless you’re in Brazil or Canada.
“The stench is awful”
There are many different pulp digesting processes. You probably worked in a sulfite mill using Black Liquor. Worst stench in the world. Permeates your body, your clothes, your car upholstery. Everything. And there’s no more fun than burning that stuff in a recovery boiler.
Of course, my experiences in pulp mills were 50 years ago, so processes have no doubt improved.
