DEVELOPMENT OF
GREEN TECHNOLOGY

What is Green
Technology?

• Technology or application
developed to minimise
the negative effects of
harmful human activities

National Green
Technology Policy

• Introduced in 2009
• Paved a way for a wider

utilisation of Green Technology
in Malaysia
• Community awareness towards
pollution an climate change
really help implementing the
policy

• Government Agency Further reading:
responsible: Malaysia Green
Technology and Climate Change
Centre (Pusat Perubahan Iklim
dan Teknologi Hijau Malaysia /
GreenTech Malaysia)

• Initiate various programmes and
incentives to encourage the
adoption of Green Technology in
various economic sectors in
Malaysia

• The usage of Green Technology is very broad across various aspects of
life.

• Examples of application of Green Technology in various sectors:

Green Technology in
Waste and
Wastewater
Management

• To ensure:
• More efficient waste
management
• Reduction in
greenhouse gases
emission
• Removal of cleaner
wastewater

Waste management

• Has to be managed properly in tandem with population increase and rapid
development

• Involving local authorities and communities to ensure the effectiveness of waste
management, especially solid wastes

• Stages in waste management:

Waste water management

• Wastewater: liquid waste that
consists of human waste, food
waste, oil and chemicals.

• Divided into:

• Domestic wastewater
• Stormwater runoff
• Industrial wastewater

• Industrial wastewater may
contain chemicals such as:

• Acrylonitrile

• Methylbenzene

• Toluene

• Heavy metal – arsenic,
mercury, lead

• Require more
systematic treatments
so that they will not
pollute the
environment nor affect
human health.



Landfill Leachate
Treatment Method

• Using the electrolysis principle –
Electrocoagulation
• Electrode: carbon or copper
• Electrolyte: wastewater

• Pollutants will form flocs
• Isolated from water and then

removed as sludge

sludge
effluent

THE IMPORTANCE OF GREEN
TECHNOLOGY IN LIFE
