•Green technology is a technology or
application developed to minimise the
negative effects of harmful human
activities.
•The usage of Green Technology is not
solely limited to the industrial sector but it
is very broad across various aspects of life.
•In application involving manufacturing of
products or services , the use of
technology with environmentally friendly
approaches is adopted to waste

11. • Green Technology is utilised in waste and wastewater
management with the aim of ensuring more efficient waste
management , reduction in greenhouse gases emission and
removal of cleaner wastewater.
• The carbon footprints can also be indirectly reduced and
various alternative methods in managing waste and
wastewater can be explored through Green Technology.

13. WASTE
MANAGEMENT
• Rapid development and growth in population have
contributed to large quantities of generated solid
waste or rubbish. If not properly managed , the
quality of life and public health will be affected.
• Waste management not only involve local
authorities but all communities must play a role in
ensuring the effectiveness of waste management,
especially solid waste.

Stages of waste
management

14. WASTEWATER
MANAGEMENT
• Wastewater is a liquid waste that consists of human
waste , food waste , oil and chemicals. Wastewater
can be divided into domestic wastewater ,
stormwater runoff and industrial wastewater.
• Compared to domestic wastewater and stormwater
runoff , industrial wastewater may contain
acrylonitrile methylbenzene, toluene and heavy
metals such as arsenic, mercury and lead.
• These hazardous chemicals are difficult to
decompose biologically and require more
systematic treatments so that they will not pollute

15. LANDFILL LEACHATE
METHOD
• By using electrolysis principle , which is also known as
electrocoagulation process , is a Green Technology
approach that can be used to treat wastewater ,
including industrial wastewater.
• Carbon or copper electrodes are used while
wastewater is the electrolyte in the electrocoagulation
process. Pollutants will form flocs and can be isolated
from water and then removed as sludge.
• After proper treatment , sludge can be used as
fertilisers for the agriculture sector or disposed of by
appropriate methods depending on the composition of
the materials contained in sludge.
