The biodegradable packaging , more commonly known as " packaging organic " are increasingly used by professionals snacking and takeaway. But, what is a biodegradable packaging? What is the difference with compostable packaging?
Definition of biodegradable packaging A biodegradable packaging is a package that decomposes in less than 6 months thanks to bacteria in the environment. There must remain only small molecules reusable by plants. What is the difference with compostable packaging? A compostable packaging is a package that must be able to degrade into compost rich in minerals in less than 3 months under certain conditions (temperature, presence of water and oxygen). The resulting compost will be used as a natural fertilizer for farmland or gardens. It avoids resorting to chemical fertilizers, very toxic for the environment. The difference is mainly in decomposition time and end use: compostable packaging is transformed into compost for use in agriculture and gardening, while biodegradable packaging, once decomposed, is used only for nature . A package can be both biodegradable and compostable if it meets the 2 criteria : disintegrate in nature in less than 6 months and disintegrate in a controlled environment for compost in less than 3 months. The EN 13432 standard defines all the characteristics of biodegradable and compostable packaging. Cane fiber plate Disposable plate made of cane fiber What are the advantages of organic packaging? Biodegradable and compostable packaging is more advantageous than traditional packaging at the 5-point level: they are made from renewable materials (wood) or agricultural waste (cane fiber) they emit less CO2 during their manufacture (up to 70% less than for plastic packaging) by being composted, they enter a renewable closed circuit they are CO2 neutral : the plant emits as much CO2 as it captures the cost of manufacturing organic packaging is decreasing more and more, whereas that of traditional packaging is increasing (in particular because of the price of oil) Which materials are biodegradable? Most biodegradable materials come from natural materials : for example, wood, palm or bamboo. But they can also come from processed agricultural waste . This is particularly the case of corn starch used for coating cups or cane fiber (also called " sugarcane pulp ") for the creation of disposable plates. Finally, some plants are at the origin of PLA (Polylactic Acid) , 100% biodegradable plastic material used to make disposable cutlery or cups. This material results from the fermentation of sugar or corn starch. As you have noticed, many biodegradable packaging is food packaging. It is clear that given the large number of take-home meals we consume each year, it is necessary to make these food packaging biodegradable . But, this is not the only type of packaging to be biodegradable and / or compostable. Thus, paper and cardboard are also biodegradable packaging , this is all the more important as these two types of packaging are used in many sectors of activity.
