Municipal Solid Waste
1. Organic waste
2. Inorganic dry waste
Waste water from bathroom,
kitchen and other usagesFecal waste from toilets/latrines
To sewerage

Unsegregated
solid waste
To municipal dumping
grounds
Disposal
1. Landfill or
2. Incineration

Population growth has been found to rise
exponentially in Indian cities
solid waste generation is
rising in the same ratio
It is no hidden fact that waste management is
poorly controlled in most of the cities
Due to urbanisation Per capita
solid waste generation has
increased to 0.6 kg per day
India is estimated to generate @1200
million tonnes of solid waste annually
Out of this 750 million tonnes is
organic waste

 Unsightly looks to the metropolis
 Extremely hazardous to health
humans, animals and plant life
 Stinking smell
 Polluted air, water and soil

Pune is one of the fastest developing
city, and generates waste about 2700
metric tons per day
About 70% of this is organic
biodegradable waste (about
1900 tons)
About 60% of the solid
waste collected by
municipal sources is
unsegregated
This unsegregated solid
waste is disposed at
landfill site near Urali
Devachi village 20 km
away from pune city
The main segregation is done on site
All solid waste is land
filled and sealed off
permanently

 PMC’s projects that by 2031, daily waste generation would reach a whopping 3,600 tonnes.
 Municipal solid waste management and transporting of waste from cities to garbage processing
areas is a costly service that consumes between twenty to fifty percent available operational
budgets for Municipal corporations.
 It is estimated that PMC presently spends around 200 crores on garbage handling & processing
 The dumping and landfill also occupies vast stretches of land which is also becoming a scare
resource

The main contributors for the Municipal Solid waste in Pune

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

The Present methods are
1. Landfill (burying or
filling in excavated
pits is landfill
2. Incineration
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

Health hazard to Human,
animal and plant life There
are over ten toxic gases
released from landfills
16
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

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

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.
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.

The Municipal bodies and the Citizens would definitely prefer their cities and residential premises to
look green, neat and clean. Pune aims to become a zero-landfill city by 2015

 Horizon has developed an innovative solution to address the management of
organic wastes
 Horizon developed a consortium of live aerobic micro-organisms for composting
organic wastes.
 This ecofriendly culture helps to accelerate the organic decomposition and reduces
the composting time to 8 to 12 days which normally can take 60 to 90 days.
 This system is completely chemical free and the bio culture is totally harmless to
human beings, animals, birds and plants.
 Designed for housing societies, restaurants, and Malls
 The equipment design has been carried out in association with CTECH, A Sine IIT
Bombay Company.
 The process is designed under the guidance of scientists from reputed institutes.
 Horizon believes that waste disposal is more of civic
individual responsibility rather than that of municipal bodies.
 Horizon also believes that segregation and processing 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

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

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”

 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

 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.

STP
To sewerage
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

 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

 The system totally coverts the human waste in clean water and gases in an
ecofriendly manner. Completely free of chemical which have adverse effects on
environment.
 No sludge removal or connecting it to the sewage line, septic tank is required.
 Greatly reduces burden on government machinery.
 The water it generates is absolutely clear and odourless. It is full of nutrients and
minerals and is good for irrigation purposes, maintain gardens, lawns etc.
 The technology leads to complete elimination of pathogens present in the human
waste which are responsible for spread of water borne diseases.
 No dependence on the limited and costly conventional energy sources.
 Application of cost-effective approach, & the system is 100% maintenance free.
 Inoculums charging is only once during the entire life of Bio Toilet.
 No bad smell in toilets from the tanks
 No infestation of Cockroaches & flies
 Fecal matter in the tank not visible fro outside.
 No clogging of digester
 Effluent is free from off odour and solid waste.
 Designed for very long life.

 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.

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.

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).

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
