What? Why? • Convert wastes into reusable material. • Recycling is a form of reuse that requires changing or reprocessing an item or natural resource. • Recycling helps extend the life and usefulness of something that has already served its initial purpose by producing something that is useable. …converting waste to wealth
Thirty years back Bel Papyrus was introduced in Nigeria with the mission of converting “Waste into Wealth” through “Waste Paper recycling”. Bel papyrus has more than 600 plus satisfied and valuable clients in Nigeria and outside Nigeria who are supporting this Green Initiative for saving Mother Earth.

Steps in Paper recycling • • • • • • •
Sourcing, Collection and Transportation Storage Repulping and screening Cleaning De-inking Refining Papermaking
…converting waste to wealth
Sourcing, Collection and Transportation
…converting waste to wealth
Contd… • You may take your sorted paper to a local recycling center or recycling bin. Often, a paper stock dealer or recycling center will collect recovered paper from your home or office. • At the recycling center, the collected paper is wrapped in tight bales and transported to a paper mill, where it will be recycled into new products. …converting waste to wealth
Storage
…converting waste to wealth
Contd.. • Paper mill workers unload the recovered paper and put it into warehouses, where it is stored until needed. • The various paper grades, such as newspapers, newsprints, calendars, magazines, cuts from printing press etc. are kept separate, because the paper mill uses different grades of recovered paper to make different types of recycled paper products. • When the paper mill is ready to use the paper, forklifts move the paper from the warehouse to large conveyors. …converting waste to wealth
Repulping and Screening
…converting waste to wealth
Contd… • The paper moves by conveyor to a pulper, which contains water and chemicals. • The pulper chops the recovered paper into small pieces. Heating/agitation by impellers breaks the paper down more quickly into fibers slurries. • Eventually, the old paper turns into a mushy mixture called pulp.
…converting waste to wealth
Contd… • The pulp is forced through screens containing holes and slots of various shapes and sizes. The screens remove small contaminants such as bits of plastics, coarse sands, pins, glasses and other contaminants. This process is called screening.

Cleaning
…converting waste to wealth
Cleaning • Mills also clean pulp by spinning it around in large high-density cleaners. Heavy contaminants like office pins, coarse sands are thrown to the outside of the cone and fall through the bottom of the cylinder through centrifugal force into rejects boxes and are removed.
…converting waste to wealth
Deinking
…converting waste to wealth
Contd.. • Sometimes the pulp must undergo a “pulp laundering” operation called deinking (deinking) to remove printing ink and “stickies” (sticky materials like glue residue and adhesives). • Papermakers often use a combination of two deinking processes. Small particles of ink are rinsed from the pulp with water in a process called washing. Larger particles and stickies are removed with air bubbles in another process called flotation. …converting waste to wealth
Refining, Bleaching and Colour Stripping
…converting waste to wealth
Contd.. • During refining, the pulp is beaten to make the recycled fibers swell, making them ideal for papermaking. If the pulp contains any large bundles of fibers, refining separates them into individual fibers. • If the recovered paper is coloured, colour stripping chemicals remove the dyes from the paper. • Then, if white recycled paper is being made, the pulp may need to be bleached with hydrogen peroxide, chlorine dioxide, or oxygen to make it whiter and brighter. • If brown recycled paper is being made, such as that used for industrial paper towels, the pulp does not need to be bleached.

Paper making Forming, Pressing & Drying
…converting waste to wealth
• The pulp is mixed with water and chemicals to make it 99.5% water. • This watery pulp mixture enters the headbox, a giant metal box at the beginning of the paper machine, and then is sprayed in a continuous wide jet onto a huge flat wire screen which is moving very quickly through the paper machine. • The weight form sheet on the wire is transferred across an open draw to a moving press felt that carries the sheet into the press section. • Then the pickup effect the transfer of the formed sheet from the wire to felt.
…converting waste to wealth
• Here, a smooth, weight, dense felt is pressed against the formed sheet on the wire and the sheet transfers to the felt. • The pickup process is headed by the fact that the web of fibres is attracted to the fine level capillary structure of the felt in preference to that of the wire. • Once the sheet has been picked up, it remained attached to the felt because of the capillary force and the water film strength that exist between the sheet and the felt. …converting waste to wealth
Dryer Section
• Because of the relatively high cost of removal of water by dryer, as compare with removal of water by mechanical means; it is of great economic importance that the sheet should be as dry as possible when it enters the dryers (Yankee). • Here, drying is carried out by a cast iron steam heated cylinder. The sheet is passed round the cylinder and held in intimate contact with the heated surfaces by means of dryer felt. • Finally, the finished paper is wound into a giant roll and removed from the paper machine. …converting waste to wealth
• Steam pressure required for drying the sheet is supplied by steam boiler and depends on the weight per unit area of paper (grammage), and then the speed of the machine and the efficiency of the ventilating system. • The Yankee cylinder is a large drying cylinder that has a highly polished surface against which the sheet is pressed by the press roll coated felt. …converting waste to wealth
