Introduction
Waste-to-Energy (WtE) in agriculture is the process of converting crop residues into energy. This approach not only addresses waste management but also offers a sustainable solution to meet energy demands. In this article, we will explore the historical background, key concepts, benefits, conversion technologies, integration with agricultural practices, case studies, current trends, challenges, future outlook, and the significance of WtE in agriculture.
Historical Background
Traditionally, crop residues have been utilized in agriculture for soil enhancement and as fodder for livestock. However, with technological advancements and the need for renewable energy, crop residues are now being used for energy generation. This field has witnessed significant milestones, including the development of efficient conversion technologies and the recognition of the environmental and economic benefits of WtE in agriculture.
Key Concepts and Definitions
WtE in agriculture involves converting various types of crop residues, such as stalks, leaves, husks, and straw, into energy. The conversion process utilizes methods like anaerobic digestion, combustion or incineration, gasification, pyrolysis, and biochemical conversion. Each method has its advantages and challenges, which we will explore further.
