    Biodegradable 可生物降解:
    In truth, everything biodegrades. Eventually, everything will break down into tiny particles. Though, the time each material takes to degrade differs greatly. Some materials break down over hundreds of thousands of years, others, degrade over a few days. GIGA only considers organic (materials made from organic matter) and inert materials as being biodegradable. This is simple when materials are considered individually. Clarity is blurred with hybrid materials. Plywood, for example, is made from wood (organic) and glue (unknown). The biodegradability of plywood hinges on the composition of its glues. Most glues are inorganic, some are inert, and  few are organic. Though few are inert. Plywood, though primarily made from organic materials, is biodegradable only if its glues inertly decompose.

    Note that organic material growth is fueled by nutrients, often from the self-decomposition. It is important that these sources receive enough nutrients to avoid additives such as fertilizers. See 'Durability' and 'Sustainable Harvesting' for more information.
