The pulp section in a paper plant is the place where the wastepaper collected from various sources is mixed with water and cleaned through various equipments to obtain the useful fibres for paper making.
Key Equipment
3-Stage Centricleaning: Centicleaning is a process through which the unwanted materials from the initial pulp are separated from the useful fibre. At Stark Ridge, this cleaning is done in three stages in order to completely rid the pulp from undesirable materials before it is fed into the paper machine.
Fractionator: Fractionator is an equipment that is used to separate the long fibres from short fibres. These contribute to separate strength properties to the paper.
Hot Disperser: Hot Disperser is used to minimize the speck level in the paper as well as to maintain a certain consistency of fibre length in the pulp.
Paper Machine is the main equipment through which the actual paper making takes place. The clean pulp obtained from the pulp section is fed into the paper machine through the Headbox. It then goes through a series of rolls which help in removal of water from the pulp through mechanisms like vaccum suction, mechanical pressing and surface heat transfer. The appropriate chemicals are also added to the paper during this process.
Consistency Regulators: Consistency regulators are used to minimize GSM variation across the width of the paper. At Stark Ridge Paper, consistency regulators are installed at every stage, right from the storage chests till the machine chests.
Size Press: Size Press is an equipment (set of rolls) that is used to add starch or other chemicals to the paper.
QCS Scanner: QCS Scanner is a device that is used for in-situ monitoring of the paper moisture and GSM levels during the paper making process. At Stark Ridge Paper, this scanner is a highly automated system with built-in feedback loops for auto-correction.
Finishing House is the place where the large rolls of paper (Jumbo Rolls) manufactured from the paper machine are cut into reels of appropriate size (as per market requirements).
Rewinder: The rewinder is an equipment that is used to cut the jumbo rolls into smaller reels (as specified by market requirements). The state-of-the-art Globe rewinder present in Stark Ridge Paper allows for flawless rewinding with minimal joints which subsequently results in trouble-free runnability at our customer’s end.
Stark Ridge Paper is committed towards maintaining a sustainable balance between industrial activity and the environment. To this end, we have invested in state-of-the-art technologies from around the world which includes: Pulp Section by Parason Machinery Paper Machine designed by Saloni Engineering (a sister company of Ruby Macons Engineering) Finishing House designed by Globe Engineering and Effluent Treatment Plant that is planned and engineered by Paques International.

Stark Ridge Paper is a Zero-Liquid-Discharge (ZLD) Plant. This means, a minimal amount of fresh water is added to the system and the chemically processed water (effluent) that is present in the system is continually processed to be reused in the plant.
The ETP at Stark Ridge Paper is a one of its kind technology which was envisioned by a joint collaboration with Paques International, who are one the leading global pioneers in effluent treatment
Reactor: The reactor in an ETP plant plays the vital role of reducing the BOD and COD levels in the effluent to their desired levels. This is accomplished through bacterial activity in the reactor.
At Stark Ridge Paper, the biogas that is generated through this bacterial activity is used in the boiler as fuel. This leads to a saving of 5-7 tons of coal consumption each day.
