Waste Management Module 2 Notes
Waste Management Module 2 Notes
1) Use Only Biodegradable & Non-Toxic Waste – Avoid materials with harmful chemicals.
2) Apply in Controlled Quantities – Prevent overloading soil with nutrients or
contaminants.
3) Follow Environmental Regulations – Ensure compliance with government waste
management laws.
4) Monitor Soil & Water Quality – Regular testing prevents pollution.
5) Compost Before Application – Pre-treatment reduces risks and improves effectiveness.
Types of aerobic compostic are
1.Windrow Composting
A windrow composting method involves creating long, narrow piles of organic material called
"windrows," which are regularly turned to facilitate aeration and promote efficient decomposition
by allowing oxygen to reach the core of the pile, leading to faster composting with consistent
temperature control; this method is commonly used for large-scale composting operations due to
its ability to handle large volumes of material and manage potential odors through regular turning.
2. Aerated static pile composting
Aerated static pile composting is a non-proprietary technology that requires the composting
mixture (i.e., a mixture of pre-processed materials and liquids) to be placed in piles that are
mechanically aerated. The piles are placed over a network of pipes connected to a blower, which
supplies the air for composting. Air circulation in the compost piles provides the needed oxygen
for the composting microbes and prevents excessive heat build-up in the pile. Removing excess
heat and water vapour cools the pile to maintain optimum temperature for microbial activity. A
controlled air supply enables construction of large piles, which decreases the need for land. Odours
from the exhaust air could be substantial, but traps or filters can be used to control them. The
temperatures in the inner portion of a pile are usually adequate to destroy a significant number of
the pathogens and weed seeds present. The surface of piles, however, may not reach the desired
temperatures for destruction of pathogens because piles are not turned in the aerated static pile
technology. This problem can be overcome by placing a layer of finished compost of 1️5 to 3️0 cms
thick over the compost pile.
4. Indore Process
5. Vermicomposting
It is the process of decomposing organic waste using earthworms. These worms consume
biodegradable waste and produce vermicast (worm manure), which is rich in nutrients and
beneficial for soil health. It is an eco-friendly and efficient method of composting that enhances
soil fertility while managing organic waste sustainably.
Process of Vermicomposting
Step 1️: Setting Up the Vermicompost Bin
Select a bin with proper ventilation and drainage holes.
Add bedding material (dry leaves, straw, shredded newspaper, coconut husk) to create a
moist, breathable environment.
Step 2️: Introducing Earthworms
Place earthworms into the prepared bin.
Let them settle for a few days before adding food waste.
Step 3️: Feeding the Worms
Add organic waste in small quantities to avoid overloading.
Chop large food scraps into smaller pieces to speed up decomposition.
Mix food waste with dry bedding to maintain the right balance.
Step 4️: Decomposition & Maintenance
Turn the compost occasionally to ensure oxygen supply.
Maintain moisture levels (sprinkle water if too dry, add dry materials if too wet).
Keep the bin shaded and at room temperature (2️0-3️0°C).
Step 5: Harvesting the Vermicompost
In 4️-8 weeks, the compost is ready.
To separate worms, move the compost to one side of the bin and add fresh food to the
other side. The worms will migrate, making it easy to collect the finished compost.
Anaerobic composting
1.Bangalore method
In anaerobic processes, anaerobic and facultative bacteria break down the organic materials in the
absence of oxygen and produce methane and carbon dioxide. Anaerobic systems, if configured
efficiently, will generate sufficient energy in the form of methane to operate the process and have
enough surpluses to either market as gas or convert to electricity. Conventional composting
systems, on the other hand, need significant electrical or mechanical energy inputs to aerate or turn
the piles. Several approaches are available for anaerobic digestion of feedstock. Single-stage
digesters contain the entire process in one airtight container. In this system, the feedstock is first
shredded, and before being placed in the container, water and possibly nutrients are added to the
previously shredded material. A single-stage digester may contain agitation equipment, which
continuously stirs the liquefied material. The amount of water added and the presence or absence
of agitation equipment depend on the particular research demonstration or proprietary process
employed.
2️.Acidogenesis (Formation of Acids & Alcohols): The simpler molecules from hydrolysis are
converted into volatile fatty acids (VFAs), alcohols, hydrogen (H₂), and carbon dioxide (CO₂) by
acidogenic bacteria.
3️.Acetogenesis (Production of Acetic Acid): The volatile fatty acids and alcohols from
acidogenesis are further converted into acetic acid (CH₃COOH), hydrogen (H₂), and carbon
dioxide (CO₂) by acetogenic bacteria.
4️.Methanogenesis (Biogas Production): Methanogenic bacteria convert acetic acid, hydrogen, and
carbon dioxide into methane (CH₄) and carbon dioxide (CO₂). This is the final stage, responsible
for biogas production.
Final Products of Anaerobic Digestion are
(i) Biogas: 60-70% Methane (CH₄) + 3️0-4️0% Carbon Dioxide (CO₂) → Used for electricity,
heating, and fuel.
(ii) Digestate: Solid and liquid byproducts → Used as organic fertilizer.
The Government has revamped the Municipal Solid Wastes (Management and Handling)
Rules 2000 and notified the new Solid Waste Management Rules, 2016 on April 8, 2016.

The Swachh Bharat Mission (SBM), launched on October 2, 2014, is a national cleanliness
initiative by the Government of India. The mission was launched to honor Mahatma Gandhi and
his vision of a clean India. It aims to improve sanitation, eliminate open defecation, and manage
solid waste effectively, thus contributing to a healthier and cleaner environment.
Mission Objectives
Eliminate Open Defecation: To make India open defecation-free (ODF) by providing access to
sanitary toilets in rural and urban areas.
Solid Waste Management: To manage solid waste effectively through waste segregation,
recycling, and disposal practices.
Promote Hygiene and Cleanliness: Encouraging cleanliness in public spaces, homes, and
workplaces, along with promoting personal hygiene.
Awareness Generation: Educating citizens about the importance of cleanliness and proper
sanitation practices.
Swachh Bharat Mission – Urban (SBM-U): Focused on improving urban sanitation, waste
management, and creating ODF cities.
Swachh Bharat Mission (Urban) primarily aims to address the sanitation and waste management
challenges in India's rapidly expanding urban areas. Launched on October 2️, 2️01️4️, SBM (Urban)
focuses on eliminating open defecation through the construction of household, community, and
public toilets. It also prioritizes establishing modern solid waste management systems tailored to
urban contexts. Key components include door-to-door waste collection, segregation at source, and
both composting and recycling facilities. Public awareness campaigns play a crucial role in
fostering behavioral change among urban residents. It promotes a culture of cleanliness and
hygiene. The mission also encourages active participation from municipal bodies, private sector
players, and citizens. It thus forms a collaborative framework to sustainably maintain urban
sanitation standards. By addressing urban-specific challenges like higher population density and
complex waste streams, SBM (Urban) aims to create cleaner, healthier, and more sustainable cities.
Swachh Bharat Mission – Rural (SBM-R): Focused on rural sanitation, including the
construction of toilets and ensuring ODF villages.
Swachh Bharat Mission (Rural), also referred to as SBM (Rural), focuses on improving sanitation
and hygiene in India's rural areas. Launched alongside its urban counterpart on October 2️, 2️01️4️,
SBM (Rural) aims to end open defecation across all villages by constructing individual household
latrines (IHHL). It also provides financial incentives to encourage their use. It emphasizes
community-led initiatives, involving village-level workers and Gram Panchayats to ensure
effective implementation and sustainability. Key initiatives include promoting behavioral change
through Information, Education, and Communication (IEC) campaigns that highlight the
importance of sanitation. Additionally, SBM (Rural) works on eradicating manual scavenging and
establishing solid and liquid waste management systems suitable for rural environments. SBM
(Rural) strives to achieve a clean, hygienic, and open defecation-free India, thereby improving
public health and quality of life in rural regions.
Key Components of SBM
Toilet Construction: The mission focuses on building individual household toilets (IHHL)
and community toilets, especially in rural areas, to prevent open defecation.
Waste Management: Segregating and processing waste in urban and rural areas is a
critical component, including composting, recycling, and waste-to-energy practices.
Public Awareness: A strong emphasis is placed on educating people about cleanliness and
hygiene through campaigns like #MyCleanIndia.
Community Involvement: Encouraging people to participate in cleanliness drives and
adopt sustainable sanitation practices.
Phase 1 (2014-2019): The initial phase focused on building toilets, eliminating open
defecation, and addressing sanitation issues in both urban and rural areas.
Phase 2 (2019 onwards): Phase 2️ continues the efforts of the first phase, focusing on
improving solid waste management, addressing plastic waste, and ensuring sustainability
in sanitation practices.
Construction of Toilets: Over 1️1️0 million toilets have been built under SBM-R to make
India ODF.
ODF Villages and Cities: Many rural and urban areas have achieved the status of open
defecation-free (ODF).
Swachh Survekshan: An annual cleanliness survey launched under SBM to rank cities
based on sanitation and waste management practices. It has incentivized cities to improve
their cleanliness standards.
Waste Segregation and Recycling: Many cities have implemented waste segregation at
source, with blue and green bins for recyclable and biodegradable waste, respectively.
A major focus of SBM is on Solid Waste Management (SWM), which is crucial to keeping the
country clean and minimizing environmental pollution. The key principles of SWM under SBM
include:
Swachh Bharat App: This mobile app enables citizens to report cleanliness issues, such
as garbage dumping or open defecation, and track the progress of SBM initiatives in their
areas.
Waste Management Technologies: New technologies like automated waste collection,
smart bins, and waste-to-energy plants are being implemented to improve waste
management.
GIS Mapping: Geographic Information System (GIS) technology is used for mapping
sanitation coverage, tracking waste collection, and managing waste processing facilities.
Infrastructure Gaps: Many rural areas still lack basic sanitation facilities and proper
waste management infrastructure.
Behavioral Change: Changing people's habits regarding cleanliness, segregation, and
sanitation practices is a challenge.
Funding: Adequate funding and resource allocation for sanitation projects and the
maintenance of toilets and waste management systems can be difficult.
Coordination Between Authorities: Effective coordination between local authorities,
municipal bodies, and citizens is necessary for the success of SBM.
Plastic Waste Management: Proper disposal and recycling of plastic waste continue to be
a significant challenge.
The conceptualization of Smart City, varies from city to city and country to country, depending
on the level of development, willingness to change and reform, resources and aspirations of the
city residents.
In the imagination of any city dweller in India, the picture of a smart city contains a wish list of i
nfrastructure and services that describes his or her level of aspiration.
To provide for the aspirations and needs of the citizens, urban planners ideally aim at developing
the entire urban ecosystem, which is represented by the four pillars of comprehensive developm
ent‐institutional, physical, social and economic infrastructure.
Smart Cities Mission is to promote cities that provide core infrastructure and give a decent qualit
y of life to its citizens, a clean and sustainable environment and application of ‘Smart’ Solutions.
