Trends and advances in bioenergy production and sustainable solid waste management

Abstract

Renewable energy accounts for 33 percent of the primary energy consumption across the world. Current world faces a major waste and climate change crisis. In many developing countries, over the past two and a half centuries, a variety of renewable power techniques have been actively pursued in distinct fields in the fields of research, growth, demonstration, manufacturing, and implementation. A replacement for fossil fuels using waste biomass is essential and considered as a promising strategy to meet our energy needs. At the same time, the emissions of greenhouse gas and managing municipal solid waste have to become crucial due to growing population demand. Biomass includes the energy stored in the sun and plants. It also serves as a primary energy source. Plants absorb the power of the sun during the process called photosynthesis. When biomass is combusted, chemical energy can be released into biomass as heat that can be used for domestic applications. The use of biomass results in management expenses contributes to climate changes, decrease the risk to lives and assets thereby ensure a safe and competitive energy source for the beneficial impact on the environment and the economy. This paper overviews about various applications of renewable energy sources produced from the municipal wastes and microbes. Prospects for the commercialization of bio-algal fuels, applications, and its challenges are discussed. The role of microbes (microalgae) in the energy production process and to use bioenergy as a future trend for economic development is discussed.
