The easiest way is to buy a second-hand paper machine (about 56 thousand, I don't know the current price) and find a rural place without wastewater treatment. Paper is charged and does not need simple handling (the equipment comes with it). Workers only need to recruit a few local farmers, and three or five hundred a month is enough.
It produces the kind of junk paper used in street stalls, and the business is very good. We have one there, and we don't need to sell it at all. At 4 o'clock every afternoon, the stall owner pushes the door open. However, it is said that his paper machine was bought by trust, and the price may actually be very expensive.
