As we learn more about how much waste we produce and the effects it has on the environment, it has emerged as a key concern for sustainable living. The zero waste movement was born as a result of how serious our garbage situation is. In response, there has also been an increase in goods with biodegradable or compostable claims. so, what are biodegradable and compostable, and are they the same thing?
What is compostable
You're actually asking a very good question if you've ever wondered what compostable means. Generally speaking, something is biodegradable if it can be safely decomposed by soil microorganisms while exposed to oxygen and added to a nutrient-rich organic soil amendment known as compost.
Despite the fact that you can certainly try one of these zero-waste dishes, composting presents the possibility of removing a significant amount of waste from the kitchen. Other items like toilet paper rolls, yard debris, and natural paper products can also be composted. Even the bamboo toothbrush handle is ideal for a washroom with zero waste.
Having said that, the type of composting system you have access to will ultimately determine what is compostable. It's not always possible to compost items at home, including animal waste, eco-friendly diapers, silicone, and eco-friendly plastic substitutes. Here, things become slightly more challenging.
This is due to the fact that there are two different composting methods to take into account: commercial and household. Home composting is the process of gathering organic material, such as vegetable scraps and yard trimmings, to make homemade plant food (compost), which can feed plants and encourage their growth.
This is a fantastic method to save rubbish from going to the landfill and put it to good use. Unfortunately, even though meat, dairy, and fish are organic materials that can be composted at home, they are not advised because of the smell they produce and the pests they might attract.
The pH balance of your compost heap can be thrown off by some vegetable waste, such as onions, garlic, and orange peels, and this will kill the worms that aid in the decomposition process. Therefore, onions and garlic might not be at the top of your list if you've ever asked "what do worms eat."
Composting operations for businesses or industries function similarly but can manage much more organic waste. Commercial operations can hasten the decomposition process and make quick work of composting a wider variety of things with the aid of machinery like grinders and chippers. Particularly noteworthy are dairy and animal products, animal waste, and absolutely all vegetable leftovers.
Compostable disposable nappies and compostable bioplastics are also accepted by some commercial facilities. Both are not advised for use in domestic composting. Applying this compost to plants intended for consumption is unsafe because eco-diapers contain feces. Additionally, they may take a while to deteriorate.
Bioplastics might take up to ten years or more to breakdown in residential systems. In fact, if a product is labeled as "compostable in industrial facilities," it must be taken to a commercial facility to decompose there in order to meet specific requirements, such as the high temperatures only possible in commercial composting systems.
However, before delivering this waste to a commercial operation, make careful to confirm whether they accept bio-based biodegradable plastics or compostable diapers. "Wishful composting" just contaminates the waste stream and increases the workload at your composting plant. What can be composted ultimately depends on the type of composting you have access to.
What is biodegradable
Biodegradable items, in contrast to compostable items, can decompose with or without oxygen. These substances can be broken down by microorganisms like bacteria and fungi in this location and converted to carbon dioxide, water, and biomass. However, this can leave behind undesirable hazardous residue that lingers in the environment and/or pollutes it, similar to "compostable" items. Therefore, just because something is biodegradable doesn't automatically make it eco-friendly.
Are biodegradable things compostable?
All compostable items are biodegradable, but not all biodegradable products are compostable. In contrast to compostable materials, which decompose into a organic material called humus, biodegradable products break down into a few different natural elements.
Natural materials that can be broken down into other natural elements (such carbon dioxide and water vapor) with the aid of fungi, bacteria, and other biological processes are referred to as biodegradable. Even some plastic is biodegradable, albeit it may take these materials generations to completely degrade.
A product must be capable of decomposing into organic matter in order to qualify as biodegradable. In general, biodegradable materials do degrade more quickly; the process normally takes three to six months. When opposed to synthetic materials, which can take hundreds of years to break down, this appears ideal. However, biodegradables can only have a lessening effect on the environment if they are disposed of appropriately and in places that control the air, moisture, and temperature.
Comparatively, composting is the process of reusing organic waste. In the right circumstances, products can degrade in a matter of months. Humus, which has a nutrient-rich composition, is produced as a result, creating a healthy soil. Composting lowers methane emissions and enables organic carbon to return to the environment (aka greenhouse gases).
