Project

local context

 

Over the years, waste management initiatives, which mostly focus on “out of sight, out of mind” strategy, have faced repeated failure due to lack of expertise, inadequate funding and utilization of ineffective, highly polluting and cosmetic solutions like landfills and incinerators. 

This absence is leading to the following problems in the bioregion of Auroville:

  • Waste dumping in nature and public spaces
  • Open-air waste burning causing air toxicity
  • Water logging due to waste obstructing drainage
  • Toxic leachates causing water and soil pollution leading to drinking water and food contamination
  • Public Health Hazards (Global Burden of Disease Report-2017 ranks India 2nd globally for premature deaths caused by Air Pollution)
  • Endangered Terrestrial and Aquatic Ecosystems like wetlands, coasts and freshwater bodies in close proximity
  • Climate change implications

Currently, Auroville has a well functioning waste management system. However, the bioregion has no proper and functioning waste management system. No bins are provided to the villages, no sustainable pick up system, no proper waste processing nor proper landfilling.

Immediate target groups

50,000 people from 14 Villages in 6 Panchayats in the Auroville Bioregion
 

Ultimate target group
Rest of India given the model’s replicable and scalable design

 

Waste to resources

WWB has conceived a zero-landfill solution for the Auroville’s bioregion which is desperately lacking any system. Through the synergies of various technologies, we aim at elevating the field of possibilities in an integrated facility that works harmoniously with a local network of similar smaller scale facilities.
This enables the reduction of difficulties that are typically emerging on big scale waste management project.

 

Profits generated must be channeled to replicate new facilities where there are none.

Making this a self-replicable solution, like a living organism.

Here below, one can see which technologies we will be using and what will be the outcome of its use.

PROJECT ACTIVITIES​

Our project comprises the following activities after micro-segregation of waste

 

    • Organic Wet Waste : Composting, composted locally with carbon mixture
      (Compost Enricher) that yields nutrient-rich compost that will be sold to the local
      farms to enrich the top soil.
    • Mixed Waste will pass through a Conveyor Belt, where recyclable waste will be
      micro segregated and the rest will pass through Trashbot, that separates any
      left-over metals through its magnetic strip & further segregates biodegradable
      from the rest into an ideal RDF with a low moisture content that can either be turned into electricity through clean plasma gasification or turned into non leachable raw construction material with a complimenting machine.
    • Recyclable Plastic – Plastic Recycling Unit – where it is shredded and then
      processed through either one of the 3 machines – the extruder, injection and
      compression machines. Each is used accordingly to the desired product, as each
      have their own qualities and possibilities on the finished product. Finalised
      products are then sold.
    • Recyclable Paper, Metal, Glass, E-Waste – Sold to the local waste dealers for
      recycling.
    • Re-Use/Re-Purpose/Upcycling Unit – to take advantage of the readily available
      resources recovered product innovation centre that can then be sold/put back
      into the system
    • Non-Recyclables, Bio-Medical & Sanitary Waste – Plasma Gasifier – processed into clean, affordable fuel (syngas and subsequently electricity to power itself and create surplus for sale) and sellable by-products (metal slag). The surplus is of a quantity so as to eventually cover the operational expenses of the system
      by the end of the project cycle, making it a financially autonomous project. Furthermore, this Plasma Gasifier has capacity to accept Non-Recyclables, Bio-medical & Sanitary Waste of neighbouring towns/cities, who are otherwise resorting to highly polluting solutions giving this project immediate scalability.
  • Non- Recyclable Paper will be transformed into bioethanol through an
    enzymatic hydrolysis of the reducible sugars which is then fermented and
    distilled. This bioethanol will be further blended up to 25% in gasoline engines
    and used in the biodiesel production using the waste cooking oil collected.
  • Waste cooking oil & CO2 from Plasma Gasifier – Microalgae Bio-Refinery – The biorefinery grows microalgae vertically using a novel photobioreactor design which is highly productive to manufacture products like biofuels, biopolymers, pigments and nutraceuticals. The fuel will mainly power our project and the surplus will be sold locally.
  • Inert materials will be minimised in the reject waste composition in order to optimise its calorific value in order to obtain higher electricity output from the Plasma Gasifier.
  • Landfills/Dumpsites – Bioremediation – Waste from these sites is collected and processed. Specific organisms will be selected upon analysis of the contaminants present in the soil. These will adapt to them through a series of lab techniques. Cocktail of organisms will be composed in order to improve their synergy in land remediation.
