Sentences with phrase «agricultural residues»
The term "agricultural residues" refers to the leftover materials or waste from farming activities. These can include crop residues (such as straw, leaves, stalks) after the harvest, or animal by-products (like manure or leftover feed) from livestock farming. These residues can be used for various purposes such as fuel, compost, or to make products like paper or animal feed. Full definition
