Value Addition to Waste for Sustainable Development

Abstract

The effect on environment by agricultural and other industrial wastes is increasing and causing a lot of problems. It is estimated that about 500 million tons of agricultural and agro-industrial residues are being generated annually in the country. Adequate means of disposing these wastes are lacking, hence, converting them to value added products such as briquettes for domestic as well as industrial fuel is desirable. This study aims to establish a mix of options for organic waste processing that can deliver better economic and environmental outcomes than the production of low quality compost or other means that have limited market potential. The present review aims at summarizing value addition options for various biomasses towards energy production and value added product generation.

Production and Characterization of Pellets from Agricultural Residue: Cotton, Tur, and Soybean

“…The results of ultimate analysis and higher heating value are given in Table 7. It is a chemical analysis that identifies the carbon, hydrogen, sulphur, nitrogen, and oxygen content of crop residue pellets [30]. Generally, biomass contains a higher amount of carbon and oxygen which makes it suitable as fuel.…”

“…Fuel thermochemical reactions including combustion, pyrolysis, and gasification are typically increased when Na and K are present. [30] However, the potassium in the area can cause metals in the processing unit to corrode. Pre-treatment with water washing and the addition of potassium sorbent to prevent potassium contamination can help to decrease harm [31][32].…”
