Role of Waste-to-Energy in SWM

According to recent estimates, the rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential increase in global waste generation of up to 18 billion tonnes by year 2020. Ironically, most of the wastes are disposed of in open fields, along highways or burnt wantonly. The increasing […]

Waste-to-Energy Conversion Routes

The conversion of waste material to energy can proceed along three main pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are […]

Trends in Recycling of Aluminium

The demand for aluminium products is growing steadily because of their positive contribution to modern living. Aluminium is the second most widely used metal whereas the aluminum can is the most recycled consumer product in the world. Aluminium finds extensive use in air, road and sea transport; food and medicine; packaging; construction; electronics and electrical power […]

Insights into Biomass Pyrolysis

Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon […]

Biomass Energy Outlook for Southeast Asia

Southeast Asia, with its abundant biomass resources, holds a strategic position in the global biomass energy atlas. There is immense potential of biopower in Southeast Asian countries due to plentiful supply of diverse forms of wastes such as agricultural residues, woody biomass, animal wastes, municipal solid waste, etc. The rapid economic growth and industrialization in […]

Biomass Energy Resources in Malaysia

Malaysia is gifted with conventional energy resources such as oil and gas as well as renewables like hydro, biomass and solar energy. Malaysia’s commercial demand for energy is projected to continue its upward trend, from 1,244 PetaJoule (PJ) in 2000 to an estimated 2,218 PJ in 2010. This consumption growth is mainly driven by industrialisation. […]
