What happens when we recycle
Newspapers and Magazines
Shredded newspapers are put into a hydra-pulper and converted to a paste. Shredded magazines are added because the clay in the magazines helps to remove the ink. Screens are used to remove contaminants. The pulp is bleached and mixed with pulp from wood chips that have been added to strengthen it. The water is drained off. The pulp is flattened out and dried by steam-heated rollers. It is then trimmed and rolled up as white blank newsprint stock later to be remade into newsprint.
Recycled newspaper is reprocessed into newsprint and wrapping paper, manufactured into molded packaging, shredded and fireproofing added for blown-in cellulose insulation or manufactured into sheet rock surfacing.
Corrugated cardboard is pulped and blended with new pulp from wood chips. The pulp is screened, rolled, and dried into two types of cardboard called medium (the ribbed inner layer) and linerboard (the smooth outer layer). Both are sold to a boxboard plant to be formed into new corrugated cardboard.
Recycled cardboard is manufactured into medium, linerboard, and paper for brown paper bags.
Aluminum scrap is ground or shredded into small chips before being melted and cast into molds. The molds are sent to manufacturing plants where they are molded or rolled into sheets that can be shaped into various products. Rolled sheets of recycled aluminum can be formed into many products, such as car bodies. Aluminum is also cast (molded) or extruded into many useful forms like soda cans.
"Tin" cans are really tin-coated steel cans. The tin coating on steel cans is removed with a caustic de-tinning solution then extracted from the solution by electrolysis. The remaining steel is rinsed, baled, and sold to a steel mill. Tin and steel are separated. The recycled tin is used by the chemical and pharmaceutical industries, and the steel is re-manufactured into cars, cans and structures. Most steel products contain some recycled steel.
Recycled glass is re-manufactured into glass containers and fiberglass insulation, and construction uses glass such as utility trench backfill and road base material, glassphalt paving.

Recycled motor oil is used to lighten bunker fuel, the heavy residue left from virgin oil refining, for use in ships; boilers, burned in asphalt plants and cement and lime kilns for processing heat and re-refining into motor oil.
Did you know?
- Each ton of recycled paper can save 17 trees, 380 gallons of oil, three cubic yards of landfill space, 4,000 kilowatts of energy and 7,000 gallons of water.
- Americans use more than 67 million tons of paper per year, or about 580 pounds per person per year.
- Making recycled paper instead of new paper uses 64 percent less energy and uses 58 percent less water.
- Every day Americans businesses generate enough paper to circle the earth 20 times.
