A review on thermochemical conversion process for energy applications by using rice straw

Abstract

Rice straw is a waste product from rice processing that is utilized as a renewable source of energy. It is one of the world's abundant lignocellulosic waste sources and has enormous potential for producing bio-energy. Due to the excessive availability of rice straw and its limited usage, the burning of straw is a common problem, which causes the reason of environmental pollution. So, the conversion of rice straw into biofuel is a good option to see its present and future scenario. There are various types of thermochemical conversion routes to convert biomass into biofuel. This review paper describes the two primarily thermochemical conversion process such as pyrolysis and torrefaction and their types and compares the advantages and disadvantages of each process. The motive of this review is just to introduce readers to the concept of rice straw and its recent use in the production of biofuels. Biofuels are a fantastic way to reduce greenhouse gas (GHG) emissions while also promoting the concept of sustainable development.
