Waste Management Technologies (SHESHA & RAPID COMPOSTING)

A Start-up Entrepreneurship Workshop was organized by Atal Incubation Centre (AIC) – BARC, DAE Convention Centre.

  • AIC-BARC is established under the ambit of the Atal Innovation Mission (AIM), NITI Aayog to create a start-up eco-system based on spin-off technologies of the Department of Atomic Energy (DAE).
  • AIC-BARC has been set up in line with the “Aatma Nirbhar Bharat”
  • In the workshop, two technologies namely SHESHA (for wet waste management) and Rapid Bio-composting (for dry waste management) were introduced by BARC scientific experts.


  • SHESHA is a novel, compact helical-shaped waste converter aimed to manage the biodegradable waste generated in small housing societies, restaurants, etc. in-situ, thus allowing decentralized processing of the biodegradable waste. 
  • The system has tremendous potential to process the waste as well as the generation of good quality fuel and manure required for soil applications. 
  • The name Shesha has been given on the basis of the serpentine shape of the digester (its resemblance to the snake Shesha) as well as the Sanskrit name of waste.

  • Helical-shaped digester made from low-cost PVC pipes.
  • Saving major costs of construction and MS dome required for conventional designs.
  • Suitable for skid mounting on vehicles or wheels required for processing waste from smaller societies/residential complexes.
  • Have inbuilt suitability for biogas recycling for methane enrichment.
  • Suitable for online monitoring of process parameters.


  • ICAR -IISS (Indian Institute of Soil Science) developed this technique in collaboration with ICAR-CIAE, Bhopal and ICAR-NBAIM, Mau.
  • It is based on cellulolytic fungi named Trichoderma koningiopsis isolated from tree bark. 
  • It is safe for the environment and for human handling. 
  • The formulation is capable of composting kitchen waste, agricultural waste, garden waste (dry leaves including coconut leaves) and temple waste. 
  • This method, being completely aerobic in nature, is devoid of foul odour and hence has greater acceptability in society.


  • Collection of biowaste materials
  • Segregation of non-biodegradable materials
  • Waste materials mixed with fresh cow-dung
  • Inoculation with a consortium of organisms
  • All materials mixed together and fed to rapo-compost bioreactor
  • After one month the humified organic manure was allowed for curing
  • Sieved (4 mm sieves) and stored at 25% moisture condition
