If you’ve already heard of PHA and PLA then you’re likely not at the start of your bioplastic journey, but you may be nearing the end! We not only offer both PHA and PLA biodegradable straws in bulk, but we’re here to walk you through the details on each so you can make the most informed decision. Whether your brand is aligned with home composting or industrial composting, we have bioplastic straws for you, on top of offering full customization.
What is PLA?
Polylactic acid (PLA) is a type of bioplastic most often derived from corn starch or sugarcane. Unlike traditional plastics made from fossil fuels, PLA is a compostable material, but it requires specific conditions to break down.
What is PHA?
Polyhydroxyalkanoates (PHAs) are naturally occurring biopolymers produced by microorganisms through fermentation. These microorganisms use carbon sources such as canola oil to create PHA, meaning it is a fully bio-based plastic.
Which Is More Biodegradable?
This is the big question when comparing these two materials for your biodegradable straws in bulk, as one breaks down much easier than the other. When considering degradability, the biggest factors are the temperature at which something will break down, and if it needs the help of any microorganisms.
PHA can degrade at natural temperatures in a variety of environments, even on the side of the road or on the beach, without leaving harmful microplastics behind. PLA, on the other hand, requires industrial composting conditions of 136.4°F and the presence of a specialized microbial community. While PLA is still bioplastic and more environmentally friendly than conventional plastic options, it may not break down efficiently in home composting or natural environments, limiting its effectiveness as a completely biodegradable material.
Common Uses & Limitations
Based on the information above, PHA is the option most used in single use packaging solutions as it offers full biodegradability. PLA can be used in many of the same ways, but it can become brittle over time, so product use is an important consideration. PHA is the material we recommend for anyone in need of bulk biodegradable straws who wants to have the least impact on the environment.
What Types of Straws Are Available in PHA & PLA?
At UrthPact, we can utilize both materials to make virtually any variety of bioplastic straw your business needs. Our most common sizes are giant, jumbo, and cocktail. Giant straws are ideal for milkshakes, smoothies, and other thick drinks, whereas jumbo straws are for your average drinks like iced coffee and soda, and cocktail for smaller drinks. We even make boba straws and can work with you to develop a product that meets your specifications.
