  13. 13. 13© 2015 All rights reserved The main contributors for the Municipal Solid waste in Pune
  14. 14. 14© 2015 All rights reserved Organic waste includes leaves, timber waste, vegetable extract, kitchen waste, household waste, hotels waste, fruits and juice residue Paper waste includes paper dish, news paper, paper box, paper bags, wrapping materials (e.g. soap cover, tooth paste cover, match box cover) etc. Plastic waste includes plastic bags, broken plastic material (e.g. mug, bucket, pipes, plastic covers, plastic wrapping material). Metal waste includes screw, nut bolt, electronic parts, damage vehicle parts etc. Glass waste includes broken glass materials, bear bottle, glass lamp, bulb, tube lights. Miscellaneous waste includes all sanitary waste Total Municipal Solid Waste
  15. 15. The Present methods are 1. Landfill (burying or filling in excavated pits is landfill 2. Incineration 15© 2015 All rights reserved Landfill site at Uruli Devachi village The most common problems associated with improper management of solid waste include 1. diseases, 2. odor nuisance, 3. fire hazards, 4. atmospheric and water pollution, 5. aesthetic nuisance and 6. economic losses
  16. 16. Health hazard to Human, animal and plant life There are over ten toxic gases released from landfills 16 16© 2015 All rights reserved Soil contamination and erosion Water contamination from the liquid that drains (leaches) Occupies land which is becoming a scarce resource (& costly) day by day landfills disposal practices attract birds, rodents and fleas to the waste dumping site and create unhygienic conditions Fire hazard (Also happened in Hanjer plant in Jan 2014
  17. 17. The Govt of India in their ‘Swatch Bharat’ campaign is encouraging disposal at source. This is to avoid a) heaps of garbage being generated b) the stinking odours associated with it c) the environmental ill effects of these d) the costs associated with the waste management e) Burden on government machinery 17© 2015 All rights reserved
  18. 18. One of the best options available to address this problem is composting the organic waste into fertilizers Composting is the process of decomposition that turns organic materials like garden waste and vegetable food scraps into a dark, crumbly and earthy smelling material called compost. 18© 2015 All rights reserved Compost is rich in nutrients and used in gardens, landscaping, horticulture, and agriculture. The compost works as a soil conditioner, a fertilizer, and as a natural pesticide for soil. In ecosystems, compost is useful for erosion control, land and stream reclamation, wetland construction, and as landfill cover.

  22. 22. The main steps in this system consist of 1. The fine compost separated for indoor plants or gardening 2. The coarse material as fertilizer for farming 22© 2015 All rights reserved
  23. 23. The main benefits of this technology are- 1. Very simple process of operation (no skilled labour required). 2. Simple and robust equipment. 3. Low cost of equipment and operation. 4. Converts organic waste into high nutrient fertilizer which can be used internally or also can be commercially sold off. 5. Completely Eco-friendly chemical free process 6. The users do not have to depend on local bodies for collection of garbage. Reduces the cost and infrastructure management on Government machinery. 7. Complete elimination of all wet waste with NO odours, NO sludge build up 8. In addition to Environmental Sustainability Impact , also ensures clean atmosphere & freedom from stinking smells. 9. Major discount in ‘property tax’ from the competent Government authorities Provides the opportunity for voluntary contribution in environ sustainability and being a part of “Swatchh Bharat Abhiyan” 23© 2015 All rights reserved

  25. 25. 25© 2015 All rights reserved  Human waste is of high concern because of its aesthetic and environmental nuisance.  Its deterioration starts even before it is discharged from the human body.  Untreated human waste leads to aesthetic nuisance, contamination of food, fruits & vegetables (direct contact, flies, rodents and contaminated water, organic pollution to water bodies, water borne diseases, viral gastroenteritis, typhoid, cholera, jaundice etc.  It consumes the dissolved oxygen of the surroundings resulting in disturbance of aquatic flora and fauna.  It is also associated with very bad stinking smells
  26. 26. 26© 2015 All rights reserved  Most cities in India lack the capacity to regulate treatment and processing of fecal sludge according to environmental and health standards.  There is also a lack of approved sewage treatment plants (STPs) in the country to safely and effectively treat fecal sludge, if it is actually collected and able to be sent there.  Presently, 95% of towns do not have the centralised infrastructure for fecal sludge processing. Only twenty-seven Indian cities have only primary treatment facilities and 49 have primary and secondary treatment facilities .  Due to the lack of functioning STPs and adequate enforcement of regulations, untreated fecal sludge is disposed indiscriminately into water bodies, drains, landfills, and vacant lands  India is the country with the highest number of people practicing open defecation: around 600 million people. This is 47% of India's population. Most of it occurs in rural areas where the prevalence is estimated at 65 percent of the population.  In most of the higher end apartment complexes and business centers, the fecal waste is mixed with the other sanitary waste waters and later attempted to be separated in STP plants.

  27. 27. STP To sewerage 27© 2015 All rights reserved Fecal Waste from toilets Waste water from baths and other areas Conventionally, the fecal waste and other wastewater are mixed up In 80% of residential houses and buildings, this waste is directly sent to sewerage lines In about 20% of residential houses, an attempt to separate these two is again made at STPs
  28. 28. 28© 2015 All rights reserved  Horizon has developed some innovative solutions to handle Fecal sludge management.  It has designed a toilet system which works on anaerobic biodegradation of feces.  Biodegradation is considered to be the most preferable way of treating the waste because of its self sustainability, cost effectiveness and eco-friendliness.  Horizon has developed a special microbial consortium to treat fecal waste. The system treats the human waste and converts it into usable water and gases in an eco-friendly manner.  The system is fully chemical free technology.  The major outcome of the innovation is provision of eco-friendly toilets, decrease in number of open defecation, and consequently improved sanitation in the surrounding areas.  No sludge disposal is required and this reduces huge burden on government machinery. Horizon has solutions for residential complexes, rural hutments, public toiletries, restaurants, Hotels corporate offices etc.  Horizon believes that waste disposal is more of civic individual responsibility rather than that of municipal bodies.  Disposal of waste, if done at source is much simpler to handle being in very small amounts, as compared to accumulating it in dumping grounds and trying to segregate/process.  Horizon’s focus initially is on smaller systems to individual societies, hotel owners, canteens, shop/mall owners etc

  33. 33. 33© 2015 All rights reserved  India accounts for 2.45% of land area and 4% of water resources of the world but represents 16% of the world population.  Total utilizable water resource in the country has been estimated to be about 1123 BCM (690 BCM from surface and 433 BCM from ground), which is just 28% of the water derived from precipitation. About 85% (688 BCM) of water usage is being diverted for irrigation.  With the present population growth-rate (1.9% per year), the population is expected to cross the 1.5 billion mark by 2050.  Due to increasing population and all round development in the country, the per capita average annual freshwater availability has been reducing since 1951 from 5177 m3 to 1869 m3, in 2001 and 1588 m3, in 2010.  It is expected to further reduce to 1341 m3 in 2025 and 1140 m3 in 2050.  Insufficient capacity of waste water treatment and increasing sewage generation pose big question of disposal of waste water.  As a result, at present, significant portion of waste water being bypassed in STPs most of the untreated waste water is unutilized and ends up into river basins.  The water supply capacity of river bodies like lakes and rivers is also fast depleting due to pollution by sewage drains and other detrimental environmental practises. http://www.ais.unwater.org/ais/pluginfile.php/356/mod_page/content/111/CountryReport_India.pdf Hence, there is an urgent need for efficient water resource management through enhanced water use efficiency and waste water recycling.
  34. 34. 34© 2015 All rights reserved http://www.ais.unwater.org/ais/pluginfile.php/356/mod_page/content/111/CountryReport_India.pdf  An estimated 38254 million litres per day (MLD) sewage is generated in major cities of India. The sewage treatment capacity is only of 11786 MLD .  Performance of state owned sewage treatment plants, for treating municipal waste water, and common effluent treatment plants, for treating effluent from small scale industries, is also not complying with prescribed standards.  Thus, effluent from the treatment plants, often, not suitable for household purpose and reuse of the waste water is mostly restricted to agricultural and industrial purposes.

  38. 38. 38© 2015 All rights reserved Pre-treatment Pre-treatment removes the materials that can be easily collected from the raw wastewater and disposed of. The typical materials that are removed during pre treatment include fats, oils, and greases (also referred to as FOG), sand, gravels and rocks (also referred to as grit), larger settleable solids and floating materials (such as rags and flushed feminine hygiene products). Secondary treatment Secondary treatment system employs an Aeration Tank wherein specially developed microorganism culture completely degrades organic as well as inorganic impurities in the presence of either Surface Aerators or Diffused Aeration system. It later settles out the biological flock or filter material and produce sewage water containing very low levels of organic material and suspended matter. Tertiary treatment The system uses “Reverse Osmosis” process to further filter the effluent. The treated wastewater is nearly indistinguishable from waters of natural origin of drinking quality (without its minerals).
  39. 39. 39© 2015 All rights reserved 1. Huge amount of water reclamation – to the extent of about 80% of wastewater 2. Extremely beneficial to housing societies, apartments, bungalows, residential complexes, restaurants, malls, industries et al 3. Reduces the strain on water supply to cities & towns to a very great extent 4. The usage of water reclamation decreases the pollution sent to sensitive environments. 5. It can also enhance wetlands, which benefits the wildlife depending on that eco- system. It also helps to stop the chances of drought as recycling of water reduces the use of fresh water supply from underground sources. 6. Low cost and efficient systems
