Waste and Wastewater Management Sector

Social-scientific issues

Improper waste disposal causes pollution and disruption of ecosystems

Social-scientific issues	Effect
Sewage, chemical wastes and rubbish disposed into the rivers and seas	Interfere with the ecosystem of rivers, seas and the surrounding areas
Food leftovers that are not properly disposed	Cause environmental pollution
Production, mangament and decomposition of solid waste	Increases greenhouse gases
Tons of paper produced in a year	Contribute to solid waste and deforestation

Application of green technology

Application of Green Technology

Prevention and reduction	Avoid using one-use containers and reduce food waste
Treatment and processing	Convert waste into energy and fertiliser through biological processes and degradation of waste by microorganism
Seperate and recycle	Separating the waste that can be reused and recycled
5R concepts	Reduction, reuse, recycle and recovery
