Abstract
An organic waste odor absorbing composition for the absorption of odors resulting from decomposing organic waste is disclosed. The composition comprises dried carbon and/or silica based matter, either natural or synthetic. The carbon-based materials consist of 35% to 85% holocellulose and 8% to 30% lignin. The silica-based materials consist of 40% to 80% silica. The materials may be mechanically sized to allow for adequate airflow and surface area exposure to the organic waste.
