WASTE TO WEALTH : PARIVARTHANA

Introduction

Parivarthana, established in 2008 within the CHRIST (Deemed to be University) campus, is dedicated to transforming waste into valuable resources and promoting responsible waste management. Our primary objective is to maintain CHRIST (Deemed to be University) as a zero-waste campus through recycling and repurposing initiatives.
At the core of Parivarthana's operations are the dedicated women within the unit, supported by student volunteers and university administration. 

Together, we strive to educate students and faculty on waste management principles, with a focus on the essential 3Rs: Reduce, Reuse, and Recycle.
The waste management unit includes various initiatives, including paper recycling, composting, and biogas generation from organic waste. Additionally, we engage in educational activities such as awareness rallies, eco-conservation programs, and the formation of eco-clubs to empower communities and promote sustainability.

 

 

 

WASTE SEGREGATION

  • Waste is collected  from waste-disposal bins placed at different points on the campus by the staff working at the Parivarthana Unit.
  • The unit segregates dry and wet waste for bio-recycling. 
  • Annually, over 70,000kg of dry waste is generated, leading to a revenue of approximately  ?5,00,000.

 PAPER RECYCLING UNIT 

 

  • Answer sheets, question papers, excess newspapers, and much more, a large variety of paper waste is produced on our campus.
  • The paper waste collected is utilized for producing various handmade products.
  • The unit has the capability to produce 2 lakh recycled products monthly.

Machines & Recycling Equipment

Explore the equipment and processes behind the Parivarthana Recycling Unit.

Hydro Pulper

Hydro Pulper

The recycling process begins at the Hydro Pulper, where raw paper waste materials—such as discarded cardboard boxes, exam papers, and chart sheets—are mixed with water to break down the physical fibers. The unit processes approximately 30 kilograms of paper with 250 liters of water per batch, running continuously for about 30 minutes to form a raw slurry pulp. Coated, plastic-laminated, or heavily dyed papers are deliberately excluded during this stage to protect the quality and structural integrity of the recycled material.

Hollander Beater

Hollander Beater

Transferred through connected piping systems, the raw pulp enters the Hollander Beater for intensive mechanical refining. To increase the ultimate strength and durability of the finished paper, pre-shredded cotton rags (prepared using a separate rag chopper) are incorporated into the mixture. Processing time ranges from 20 minutes for plain paper stock up to 3 hours when cotton rag reinforcing fibers are added. Pure cardboard processing does not require additional cotton rag blending.

Disc Refiner (TDR)

Disc Refiner (TDR)

Following primary beating, the pulp slurry flows into the Disc Refiner to achieve a high level of fiber uniformity and surface smoothness. The machine utilizes precision rotating disc plates to separate coarse fiber bundles, ensuring the pulp attains an even, fine consistency critical for producing consistent sheet weight and quality.

Pulp Agitator

Pulp Agitator

Positioned inside a tiled storage basin, the Pulp Agitator uses motor-driven paddles to continuously circulate and suspend the refined pulp slurry. This continuous agitation prevents settling or separation of fibers and water, preserving a smooth, homogenous mixture ready for immediate distribution to the paper forming assembly.

Paper Flow Mould Machine

Paper Flow Mould Machine

The Paper Flow Mould Machine forms continuous wet paper sheets by spreading the conditioned pulp mixture evenly across a moving conveyor wire mesh belt. As the belt advances, gravity and vacuum drainage remove excess water, allowing the cellulose fibers to interlock into flat, continuous sheets prior to drying and press calendering.

Semi-Automatic Paper Cutting Machine

Semi-Automatic Paper Cutting Machine

The Semi-Automatic Paper Cutting Machine is engineered for heavy-duty trimming and accurate dimensioning of dried paper stacks. Equipped with precise back-gauge controls and safety mechanisms, it cuts bulk paper sheets down to standard sizes required for manufacturing notebooks, registers, file folders, and customized board products.

Hydraulic DIE Press Machine

Hydraulic DIE Press Machine

The Hydraulic DIE Press Machine utilizes controlled fluid power to apply uniform high pressure onto paper sheets and board stocks. It is used to shape, cut, or emboss specialty items and heavy-duty components, ensuring precise edges and high structural density for custom stationery and packaging solutions.

Paper Creasing Machine

Paper Creasing Machine

The Paper Creasing Machine creates clean, sharp, crack-free indentations and fold lines on heavy paper stocks, cardboards, and hardbound book covers. Featuring adjustable pressure screws and aligning guides, it enables smooth manual or automated folding for files, gift boxes, and brochure covers.

Organic Waste Compost Machine

Organic Waste Compost Machine

Supporting zero-waste circular operations, the Texonics Organic Waste Composting Machine processes food scraps, garden refuse, and biodegradable waste generated across the facility into nutrient-rich compost. Featuring automated temperature and agitation control panels, the stainless steel unit rapidly decomposes organic material while maintaining clear visual operating guidelines.

Display Room Showcase

Display Room Showcase

The Display Room features custom glass-fronted, backlit cabinetry designed to store and present the full range of upcycled finished goods created by the unit. The curated exhibition showcases hardbound notebooks, handcrafted journals, gift boxes, paper bags, certificates, and eco-friendly custom stationery—demonstrating the complete transformation of waste into high-value sustainable products.

COMPOSTING

 

  • The unprocessed wet waste, along with plant debris, decomposes to form organic compost.
  • Equipped with four composting tanks, each with a capacity of 1500 kg, it produces over 2,500 to 3,000 kg of compost annually, generating revenue of approximately a lakh every year. 
  • The unit utilizes this compost within the campus and sells the surplus.

 

 

WATER TREATMENT PLANT

 

  • The used water undergoes treatment in the water treatment plant, where it achieves a purity level of 98%. This treated water is then utilized for vegetation and gardening purposes. 
  • On average, 1.5 to 2 lakh liters of water is recycled daily.

 

 

 

BIOGAS

 

  • The wet waste is utilized to produce biogas. The facility is equipped with two biogas tanks, each with a capacity of 150 kg, and one tank with a capacity of 200 kg.
  • On average, the plant processes over 1.3 to 5 lakh kgs of food waste, yielding more than 5,500 to 6,000 kgs of LPG valued at over ?5 lakhs annually.

 

 

 

SHG AT PARIVARTHANA

 

  • Parivarthana unit exemplifies the spirit of unity through its diverse team of dedicated individuals.
  • In 2019, a Self-Help Group (SHG) was established within the Parivarthana Women Common Interest Group (CIG), fostering holistic empowerment and financial stability among women.
  • The SHG initiative underscores Parivarthana's commitment to promoting collaborative efforts and fostering a supportive environment for personal and professional growth.
