DW-HSE-TM022 22

23. SEGREGATION
DW-HSE-TM022 23
Waste segregation is the practice of
separating different types of waste at the
source to facilitate recycling and proper
disposaL
At the Source:
•Waste segregation starts at the point where
waste is generated, which is typically in
homes, businesses, institutions, or industrial
facilities.
•Individuals and organizations sort their waste
into different categories based on the nature of
the materials.
• Waste chemicals
• Waste lubricants
• Oily sand
• Tank & other sludge
• Batteries
• Tires
• Oil drums (empty)
• Clinical waste

30. Ways to Solve Waste Disposal Problems
• There are 5 essential steps in the waste lifecycle:
1.Waste generation
2.On-site waste management
3.Waste collection
4.Waste transfer
5.Waste processing and disposal
DW-HSE-TM022 30

31. CONT-
• Waste Generation
Waste generation happens everywhere:
• households,
• commercial facilities,
• industrial sectors.
Solid waste management is only as actionable as a
company’s awareness about the types and frequency of
the waste they produce. For example, an office may
primarily generate paper waste, while a restaurant
creates food waste, and a construction site generates
rock waste. What kind of waste do you generate and
process?
DW-HSE-TM022 31

32. On-Site Waste Management
• On-site waste management addresses how a company
stores the particular types of waste they produce.
Having a skip bin on-site may not be the most
suitable solution for the kind and volume of waste a
given company generates. If you find that your skip
bin is overflowing long before collection day, you
may need a more advanced on-site waste management
solution, like a baler. Balers compact recyclable
materials into blocks, reducing the volume of waste.
DW-HSE-TM022 32

33. Waste Collection
• The next step in the waste management process is
waste collection. During waste collection, garbage
trucks (transfer trailers) come to a facility and
collect the waste from garbage cans, recycling bins
and skip bins.
DW-HSE-TM022 33

34. Waste Transfer
• After the transfer trailers collect the waste from facilities around DOHA,
they bring it to a waste transfer station. This is one of the most critical
steps for council-level decision-makers because modern waste and
recycling equipment can sort and handle waste more effectively.
• Waste transfer stations sort and consolidate waste from various sources
so it can be transported to the proper facility. For example, a disposal
vehicle arrives at a waste transfer facility with mixed waste and
recyclables. The waste is unloaded and moved through a sorting system
to separate garbage, different recyclables, hazardous waste, etc. Then, it
is reloaded into the appropriate transfer trailers and taken to a facility for
processing and disposal.
DW-HSE-TM022 34

35. Waste Processing and Disposal
• When the transfer trailers arrive at the
appropriate facility, the facility then must
process and dispose of the materials. For instance,
paper waste goes to a recycling facility for
processing. Garbage goes to a landfill. Hazardous
waste goes to a special facility for safe disposal
and storage.
• Having proper waste processing and material
recovery facilities is the most critical stage of
solid waste management. If materials aren’t
processed correctly, and facilities lack proper
waste and recycling equipment, then it discredits
all of the previous steps to crush, compact, sort
and transport the waste.
DW-HSE-TM022 35

36. In-Depth Exploration of the 3 R's: Reduce, Reuse, Recycle:
Reduce:
• Source Reduction: Emphasizes minimizing the generation of waste at
the source by using fewer materials and opting for products with less
packaging. This principle focuses on conscious consumption and
encourages a shift toward a more sustainable lifestyle.
• Product Design: Advocates for designing products that are durable,
repairable, and have a longer lifespan. This approach considers the
entire life cycle of a product, from production to disposal, and aims to
reduce the overall environmental impact.
DW-HSE-TM022 36

37. Reuse:
• Promoting Reusables: Encourages the use of reusable items instead
of disposable ones. This includes using refillable water bottles, cloth
shopping bags, and durable containers for food storage. The goal is to
minimize single-use items and promote the longevity of products.
• Repair and Maintenance: Encourages repairing items instead of
discarding them. Learning basic repair skills and supporting repair
services contribute to extending the life of products, reducing the need
for frequent replacements.
• Second-Hand Markets: Embraces the idea of buying and selling
second-hand goods. Thrift stores, online marketplaces, and community
swap events facilitate the reuse of items, giving them a new life and
diverting them from landfills.
DW-HSE-TM022 37

38. Recycl
e:
• Separation of Materials: Involves sorting waste into different
categories to facilitate recycling. Materials like paper, glass, plastic,
and metal are collected separately to maintain their quality during
the recycling process.
• Community Recycling Programs: Encourage community
participation in recycling programs. Providing accessible recycling
bins, educating residents about the importance of recycling, and
implementing collection systems contribute to increased recycling
rates.
DW-HSE-TM022 38

39. Practical Strategies for Incorporating the 3 R's into
Everyday Life:
Reduce:
• Mindful Consumption: Be mindful of purchasing decisions, opting for
products with minimal packaging and considering the environmental
impact of products.
• Bulk Buying: Purchase items in bulk to reduce packaging waste.
Bring reusable containers when shopping for items like grains, nuts, or
cleaning supplies.
• Digital Alternatives: opt for digital formats (e-books, online
subscriptions) rather than physical copies to reduce paper
consumption.
DW-HSE-TM022 39

40. Reuse:
• Reusable Products: Invest in reusable items such as water
bottles, coffee cups, and shopping bags to minimize the use of
disposable alternatives.
• Upcycling Projects: Explore creative ways to repurpose items.
Turn old clothing into rags, transform jars into storage containers, or
use old furniture for DIY projects.
• Community Swap Events: Participate in or organize swap events
within your community where people can exchange items they no
longer need.
DW-HSE-TM022 40

41. Recycle:
• Know Your Local Recycling Guidelines: Familiarize yourself with
the recycling guidelines in your area to ensure proper sorting.
Different materials may have specific recycling instructions.
• Set Up Recycling Stations: Create dedicated recycling stations at
home or in the workplace with clearly labeled bins for paper, plastic,
glass, and metal.
• Support Recycling Initiatives: Participate in or support local
recycling programs and initiatives. This could include volunteering
for clean-up events or encouraging businesses to adopt eco-friendly
practices.

•Discuss on Importance of
Involving Communities in Waste
Management Initiatives
DW-HSE-TM022 42

43. Importance of Involving Communities in Waste Management
Initiatives:
• Behavioral Change: Community involvement is essential for fostering a sense of
responsibility and encouraging behavioral change. When individuals understand
the impact of their actions on waste generation and disposal, they are more likely
to adopt sustainable practices.
• Local Knowledge and Solutions: Communities possess valuable local
knowledge about waste generation patterns, cultural practices, and environmental
concerns. Involving them in waste management initiatives ensures that solutions
are context-specific and culturally appropriate.
• Effective Waste Segregation: Community participation is crucial for successful
waste segregation at the source. When residents actively segregate their waste
into recyclables, organic matter, and non-recyclables, it streamlines the recycling
process and reduces contamination
• Education and Awareness: Engaging communities in waste management initiatives provides an
opportunity for education and awareness campaigns. Workshops, seminars, and community events can
inform residents about the importance of waste reduction, recycling, and proper disposal practices.
• Reduced Illegal Dumping:When communities are actively involved in waste management, there is a
decrease in illegal dumping and littering. Residents become stakeholders in keeping their neighborhoods
clean, leading to a more aesthetically pleasing environment.
DW-HSE-TM022 43

44. Cont-
• Job Creation and Economic Opportunities: Community-based waste management
initiatives can create jobs and economic opportunities. Recycling programs, waste
collection services, and composting projects can provide employment for local
residents, contributing to community development.
• Social Cohesion: Collaborative waste management initiatives can enhance
social cohesion within communities. Working towards a common goal, such as
waste reduction, can strengthen community bonds and instill a shared sense
of responsibility.
• Environmental Impact:
• Regulatory Compliance:
• Brand Image and Reputation:
