2017/11/6. Waste materials business
Waste materials business has 2 kinds of incomes, reserving money when taking over the wastes, and selling with using them.
I am working at pavement company in Japan, and I realize that these 2 kinds of incomes are very big. Recycling from old pavement to new, has high profit.
Pavement recycling has to be done in all world, because there are many chances and low environmental loads.
And these 2 kinds of incomes can be applied to other fields.
