What's Inside? 125 Packs of 5 deep compartment white square biodegradable plates with dimensions 10.24" x 8.27" x 0.91" (26.57cm x 21.12cm x 2.8cm). A biodegradable divided plate is a type of plate that is designed to be environmentally friendly and can break down naturally over time through biological processes. Unlike traditional plastic or styrofoam plates that take hundreds of years to decompose and can contribute to pollution, biodegradable plates are made from materials that can be broken down naturally. The divided design of these plates usually features separate compartments or sections to keep different types of food separate from each other, similar to a segmented tray. They are often used for serving meals that have multiple food items or for portion control.
