It depends on what they’re made of.įor composting, we need to look for bags that are specifically made (and certified) for this purpose. Some biodegradable bags are compostable, but not all. You might see words like “photodegradable” or “oxo-degradable”, which means plastic bags that break down in sunlight or air, respectively (read: living organisms aren’t involved).īut when they enter the environment (where living organisms are present), biodegradable plastic bags are just as bad as regular plastic trash bags (despite their much higher price tag)!Īre biodegradable garbage bags compostable?Ĭompostable and biodegradable bags are one in the same, right? However, their breakdown rate depends on what these bags are made of and where they end up. How long does it take biodegradable trash bags to decompose?
That, and they’re generally quicker to break down than conventional plastic trash bags.

One benefit of all bioplastics is that they are free of toxins like bisphenol A (BPA).
Mater-Bi is another type of plant-starch bioplastic and true cellophane (as opposed to synthetic cellophane) is made from regenerated wood cellulose. This microbe-made PHA has a plastic-like structure that can be harvested for trash bags as well as food packaging, medical products, and more. It’s made from genetically-engineered microorganisms that consume organic materials to produce carbon reserves. The starch is then separated out, some citric acids are mixed in and voila, we have PLA that can be used as an alternative to polyethylene, polystyrene, and polypropylene.Īnother type of bioplastic is PHA or polyhydroxyalkanoate. To make PLA, the sugars found in sugarcane, corn starch, or cassava are immersed in a hot water-sulfur dioxide solution so that the different components (fiber, protein, and starch) become “available”. One of the most common types of bioplastic is PLA (polylactic acid). What are biodegradable trash bags made of?īiodegradable trash bags typically fall into two material categories: biodegradable plastic bags and those made with bioplastic.īiodegradable plastics are typically just petrochemical-based plastic designed so that exposure to certain things will help them break down faster.īioplastic, on the other hand, is usually made from plant-based and renewable materials, like corn, grains, sugarcane, starches, and vegetable oils. Until you realize that plastic being broken down into microplastics is not an eco friendly way to dispose of household waste, dog poop, or anything.
Before we dive into biodegradable bags, here’s a quick refresher on what it means to be “biodegradable.”Īccording to Merriam-Webster, biodegradable is that which is “capable of being broken down, especially into innocuous products by the action of living things (such as microorganisms).”
