objects which are disposed of or
are intended to be disposed of
or are required to be disposed
of by the provisions of national
law (Article 5 of the Basel
Convention
Waste (or wastes) are unwanted
or unusable materials.Waste is
any substance discarded after
primary use, or is worthless,
defective and of no use.

5. Classification of waste

7. Waste management
Waste management means activities relating to the
collection, transportation, storage, treatment and
disposal of waste, including the management of
waste at source and during decommissioning of
waste management facilities

8. Waste management hierarchy

9. Management of organic waste
Organic waste is any
biodegradable material that
comes from living organisms
and undergo rapid
decomposition.
Biodegradation is the
breakdown of organic
matter by microorganisms,
such as bacteria and fungi.
Examples of biodegradable waste materials include;
Waste food, paper, plant remains, human waste, manure,
sewage etc

10. Management of organic waste
This can be achieved through the following strategies;
 Buy and cook only what you need
 Properly store your food materials (refrigeration, salting, sun drying etc
 Make good use of your leftovers e.g. donating leftover food to the
needy
 Add to plant soils
 Composting
 Convert food waste into biogas
 Divert leftover food and other wastes like banana peelings into animal
feed
 Ingeneration
 Disposal
NB: Use the green plastic dustbin to collect the biodegradable waste
materials while at project sites. Ensure to make good use of the food
waste pit at main camp to compost biodegradable materials.
Note: The UN Food and the Agriculture Organization claim that each year nearly 1.3 billion tonnes of food is
wasted across the globe. Food wastage occurs at the various levels of the food system, namely farming,
processing, transporting, retailing, cooking, and consuming.

11. Management of recyclable waste
Recyclable material means any material or group
of materials that has or retains useful physical or
chemical properties after serving its original
purpose(s) or function(s), that is collected,
separated or processed, and returned to the
economic mainstream in the form of raw
materials or products.
Examples of recyclable wastes generated in our
surroundings include plastic bottles and
containers, food and beverage cans, glass bottles
and containers, paper, cardboards, steel, aluminium
etc

12. Management of recyclable waste continued…
 Reducing the amount of solid waste generated
 Recycling as much refuse as possible
 Transforming waste in an environmentally safe manner
 Proper onsite collection and sorting. Use the blue
plastic dust bin to collect plastics, glasses etc for
Mpanga project sites.
 Safe disposal

13. Management of recyclable waste continued…
Common examples of products made out of recycled materials
include; bicycle tires, glass countertops, paper notebooks, furniture,
carpets, bags, glass bottle vases, decking, recycled aluminium Jewry,
planters etc

14. Management of recyclable waste continued…

15. Plastic pollution
Plastic pollution is the accumulation of synthetic plastic
products in the environment that reaches an extent where it
causes problems for wildlife habitats, ecosystems and
human populations.
How does plastic pollution occur
Poor garbage disposal habits among some people who litter everywhere and
anyhow especially after using polythene bags, plastic water, beverage bottles
and other non-biodegradable packaging materials lead to increased amount
plastics within the environment. During rainy season, these plastics are washed
into water channels, rivers and lakes where they result in mountains of
garbage heaping up. They then chokes fresh water ecosystems, damages soils
and poisons ground water. For example; these (waste) come along with
microplastics and pathogens which find their way into the food chain like the
fish, crops we eat and everything we get from the soil.

16. Impact of plastic pollution
 Indiscriminate disposal of plastics leads to clogged drainage
systems, worsening the risk of flooding during rainy season
 Wildlife, both on land and in water suffer dire consequences as
they get entangled in plastic debris or mistake it for food,
leading to injury, starvation and death.
 Soil fertility loss
 Ground water poisoning
 Reduced environment aesthetics

17. Examples of local innovations to reduce plastic accumulation
 Use plastic bottle tops as exterior decoration
 Using plastic bottles and polythene bags as bricks (bottle bricks) for
construction of housing facilities
 Use plastic bottles and polythene as flower pots or for backyard
agriculture

19. What a beauty!

20. Management of hazardous waste
Hazardous waste is waste that has substantial or potential
threats to public health or the environment.They usually have
one or more of the following hazardous traits: ignitability,
reactivity, corrosivity, toxicity.
Examples of hazardous waste
• Motor oil, bearing oil
• Automobile batteries
• Paints and solvents
• Household cleaners
• Drain openers
• Pesticides
• Compressed gas tanks (such as propane and oxygen)

21. Significance of hazardous waste
Dumping solvents into septic systems or landfills may
contaminate ground and surface waters ruining drinking
water and killing fish and wildlife.
Pesticides can damage sewage treatment plants, and oil
poured into storm drains can flow directly into streams
and ponds.
Risk of explosion
Long-term and short-term effects on human health
(through contact, ingestion, inhalation)

22. Ways of managing hazardous waste at Mpanga HPP
Mpanga hydropower plant has plastic colour coded dust bins in
every site. Use the red bin to collect all waste materials that are
hazardous in nature. Don’t forget to use heavy duty gloves, overall,
safety gumboots and a mask while handling such wastes. Make use
of the data sheet to clearly understand the nature/behaviour of the
hazardous material you're dealing with.
The plant also has a licenced storage facility for hazardous waste.
Regularly inspect the facility and check for any leakages and
cleanliness. Fortunately, the project has a memorandum of
understanding with a licenced party to collect, transport and
dispose of such waste on accumulation.

23. Management of spills
1. Identify the substance and determine the risk
2. Protect yourself
3. Stop the spill
4. Contain the spill
5. Minimize the risk
6. Clean up the spill
7. Decontaminate

24. Metal waste or scrap metal is any product that's broken
or no longer useable, which is made completely or mostly
from a metal material. For example, it could be broken
tools, metal sheets from manufacturing, a bent pipe, old
electrical appliances, and more.
Most heavy metals cause environmental and atmospheric
pollution, and may be lethal to humans. Heavy metals can
become strongly toxic by mixing with different
environmental elements, such as water, soil, and air, and
humans and other living organisms can be exposed to them
through the food chain.
Management of metal waste/scrap metal

25. Tips to proper management of metal
waste at Mpanga HPP
• Sort the metal scrap
• Recycle metal waste
• Donate useful old items like metal plates, saucepans,
cups etc
• Reuse

26. Electronic waste management
E-waste is electronic products that are unwanted, not
working, and nearing or at the end of their useful life.
Examples include;
• Old CRT tube televisions.
• LCD, OLED, and plasma televisions.
• LCD monitors, smart displays, and tablets.
• Laptops with LCD monitors.
• OLED desktop monitors, laptops, and tablets.
• Computers, computer monitors, and printers.
• VCRs.
• Portable DVD players with video screens.

27. Easy ways to manage E-waste at Mpanga HPP
• Know the product’s lifespan before you buy it
• Buy what you need
• Check the packaging for an environmental seal
• Share information about E-waste
• Learn about electronic components
• Donate unwanted electronic equipment
• Make recycling part of your lifestyle
• Landfilling and incineration (done by licenced parties)
Note: In Uganda, the E-waste management policy was approved by parliament in
2012.The guidelines on E-waste management are available.

28. Management of waste water
Waste water can be defined as used water from any
combination of domestic, industrial, commercial or
agricultural activities, surface runoff/storm water, and any
sewer inflow or sewer infiltration.
The main types of wastewater are:
1. Greywater – from showers, baths, hand basins,
washing machines, laundry troughs and kitchens.
2. Blackwater – for example, toilet waste.
3. Sewage – a combination of greywater, blackwater and
trade waste.
4. Industrial wastewater – includes all wastewater waste
except sewage.

29. Management of waste water continued…
Wastewater can contain microorganisms, bacteria and viruses that can cause disease.This can
include eye and nose infections or gastroenteritis (gastro or upset stomach).Wastewater can also
contain pollutants.These can impact water quality, harm plants and animals and present risks to
human health.
Pollutants include:
 Suspended solids or sediment – soil, sand and other particles can build up in waterways
 microorganisms – can spread disease (for example, harmful bacteria, virus, protozoa and
helminth)
 Chemicals and heavy metals – in industrial waste and naturally present in the environment.These
can be harmful in large amounts.
 Nutrients (Nitrogen and Phosphorus) – wastewater high in nutrients entering a water body can
cause harmful algal blooms that impact water quality and cause fish kills.
 Water with too high or too low pH also presents a risk to the environment (biota) and human
health when there is close human contact.
All these can impact water quality, harm plants and animals that depend on water and present risks
to human health.

30. Management of waste water continued…
Mpanga HPP has septic systems and soak pits to manage waste
water at all sites.
Tips for proper maintenance of septic tanks
o Inspect regularly – check for any foul smell, leakage and
damage
o Use water efficiently
o Properly dispose of waste – toilets are not trash cans. Avoid
cooking grease or oil, non-flushable wipes, such as baby
wipes or other wet wipes, photographic solutions, feminine
hygiene products, condoms, dental floss, diapers, cigarette
butts, coffee grounds, cat litter, paper towels,
pharmaceuticals, household chemicals like gasoline, oil,
pesticides, antifreeze, and paint or paint thinners.
