- 3. Observed Paperwastage in schools, colleges and offices. Why we don’t have own paper recycling facility ? To start working on project which provide small scale paper recycling in office, schools and colleges.
- 4. Why wechoose to do research on recycling process rather than production of paper from wood fiber? The primary source of paper making is vegetable fibers. This leads to depletion of forest and disturbs environmental balance. So the only way out is to use recycling process.
- 5. The fullscale plant is available world wide but the use those in offices and school is not possible so to resize the whole plant in single small scale portable machine.

- 9. Paper breakingproblem between calendaring and winding process. Lack of automation in winding process.
- 10. Lack ofsynchronization between calendar rollers and winding rollers. Variable peripheral speed of winding rollers. Tensile force in paper because of lagging of speed of calendar rollers and winding rollers.
- 11. Synchronization ofcalendaring rollers and winding rollers. Waste heat Recovery system
- 12. The paperis the not strong in tension, due to which it breaks when the tension is applied on the paper. This tension on paper mainly occurs due to uneven speed of motor on pulping or formation side and the motor on the reeling side. The uneven speed of motor forms bubbles on the surface of the paper reel and sometimes the paper also breaks. To avoid this the synchronization of speeds is to be done INNOVATIONS IN PROJECT :
- 14. The paperbreaking problem was due to amount of moisture content in the paper was remaining higher than desired. Due to higher moisture content in the paper at dry section the paper when comes in tension breaks. To bring the amount of moisture in required levels the input of heat can be done through waste heat recovery system. The boilers in industries and chimney of kitchen in colleges and offices has lots of waste heat. This heat can be utilized to take away all the remaining moisture from the paper which will reduce the size of the machine and avoid the breaking of paper.
