The process of recycling waste by utilizing the waste as an additive ingredient in the manufacture of Portland cement substituting for virgin ingredients normally used in the manufacture of the Portland cement eliminating the need for disposing of the waste in a landfill where the Portland cement is produced from a cement clinker which has been produced by burning, said process comprising the following steps:
- obtaining a first quantity of a waste selected from the group consisting of latex paint, water base paint, water-soluble pigments, water-soluble adhesives and water-soluble resists with waste being in liquid form or in solid form, or in a combination of liquid and solid;
- obtaining a second quantity of a solid material selected from the group consisting of calcium carbonate, combustion ash, diatomaceous earth, perlite, slag fines, aluminum dross fines, clay fines, pyrite ashes, cinder fines, shale fines, bauxite, silica sand and dolomite;
- mixing thoroughly together said first quantity and said second quantity producing a non-compacted additive having the consistency of wet earth that is readily pliable with the second quantity by weight not exceeding three times the first quantity by weight;
- adding the additive as an ingredient in the manufacture of Portland cement with this adding occurring after the burning of the raw materials producing cement clinker;
- and
- pulverizing of this cement clinker and at the same time evenly mixing of the additive.
