Food waste—such as leftovers, discarded vegetables, peels, and eggshells—contains significant amounts of protein that can be recycled into animal feed and fertilizer. The cooking oil within food waste can also be extracted and converted into fuel to help meet the growing energy demand. With proper implementation, these recycling processes can not only mitigate environmental problems and reduce pressure on public resources but also generate economic benefits and create incentives for broader participation in waste recycling.
