A review of sustainable biofuels from waste materials: development and challenges

Abstract

Biofuel is a fuel derived from living things or their wastes (biomass) that is considered as the most potential and alternative energy source. It includes bioethanol biodiesel, biohydrogen, biogas, etc. Due to its environmental merits, biofuels production is increasing all over the world to deal with the energy crisis. Usage of biofuel has already shown promising results to deal with reducing greenhouse gases, non-renewable and unsustainable resources. Though biofuels may concern food security, developing countries are trying to project numerous targets for producing biofuels using various waste materials such as food waste, sewage sludge, food industry waste, etc. The purpose of our review article is to gather data on the production of biofuels from different waste raw materials reported globally and further analyze the possibility as well as the potentiality of those biofuels in Bangladesh.
