Abstract
The global waste generation keeps increasing over the years and it requires innovative solutions to minimize its impacts on environmental quality and public health. A strategic plan must be ascertained to overcome the future challenges of Municipal solid waste (MSW) locally and globally. Universiti Putra Malaysia (UPM) coined an initiative to demonstrate a showcase pilot plant for green energy production from MSW. The data was obtained from the survey and actual sampling within the UPM compound shows that UPM has generated 5.0–7.0 t/d of MSW generated consist of 30–35% organic fraction. Restaurants are the main source of the organic fraction. Upon separation, the organic fractions were digested into biogas. At a maximum conversion of the organic fraction, 715 kWh of electricity might be generated from the 2.2 t/d of organic waste generated in UPM. In this study, organic components from UPM were proposed to be subsequently used as a substrate via anaerobic digestion to produce green energy in the form of electricity or flammable fuels.
Highlights
Municipal solid waste (MSW) is a solid waste that is commonly described as trash or garbage that is generated daily by household, commercial establishment, industries, and others
The growth in urban population contributes to the increasing food consumption, which leads to the increasing MSW generation in Asian countries [6]
The scope of this study is to evaluate the current generation, composition, and management of MSW in Universiti Putra Malaysia as a showcase for the reference, and to propose improved utilization options of organic waste for the waste-to-wealth projects in Malaysia
Summary
Municipal solid waste (MSW) is a solid waste that is commonly described as trash or garbage that is generated daily by household, commercial establishment, industries, and others. It is regarded as an inevitable and valueless by-product due to community activities. Malaysia is experiencing an increase of urban population growth, leading to the development, rapid urbanisation and industrialisation, and contributes to the increment of MSW generation [10]. The scope of this study is to evaluate the current generation, composition, and management of MSW in Universiti Putra Malaysia as a showcase for the reference, and to propose improved utilization options of organic waste for the waste-to-wealth projects in Malaysia
