The Different Types of Biodegradable Straws

Of the nearly eight million tons of plastic waste, plastic straws make up about 4% of that total. They are also among the top 10 contributors to ocean marine debris. Plastic straws are not recyclable, partly because of their size but also because most are tossed into the trash and end up in a landfill. 

Business owners and shoppers have become more committed to adopting plastic straw alternatives due to the increase in environmental impact research on single-use plastics. Businesses that switch to sustainable straws often report positive feedback from customers who appreciate their commitment to environmental sustainability. With this, biodegradable straws are starting to replace plastic straws, but with so many different types on the market today, you might be wondering how to choose. 

In this guide, we examine different environmentally friendly drinking straws and compare their sustainability and durability so you can make informed choices that align with your values to contribute to a healthier planet.

What are Biodegradable Straws?

Biodegradable straws are a type of straw that can decompose naturally into the environment without causing harm. When discussing biodegradability, we refer to a product’s capacity to break down in an environment. Different materials break down at different rates, so knowing and understanding the properties of each material may help you choose the best biodegradable straw for your needs.

Plastic Straws vs Biodegradable Straws

Plastic straws can take hundreds of years to decompose and often end up in landfills or oceans, where they can harm wildlife and pollute waterways. 

Biodegradable straws decompose naturally into the environment without causing harm.

The Benefits of Biodegradable Straws

While both biodegradable and recyclable straws have multiple benefits over plastic straws, they have different end-of-life cycles. Recyclable straws help reduce waste and conserve resources by being processed and reused to create new products or materials.

Biodegradable straws provide more benefits to the environment by combating environmental pollution:

• Environmental impact: Biodegradable straws break down naturally, reducing waste in landfills and oceans.
• Renewable resources: Renewable sources lessen straw manufacturing’s dependence on finite fossil fuels.
• Healthier option: Biodegradable straws are made from plant-based materials and offer a safer choice to health-conscious individuals than plastic straws that may contain toxic additives.
• No microplastics: Biodegradable straws decompose naturally without forming harmful microplastics that can impact ecosystems and human health.
• Greenhouse gas emissions reduction: Using biodegradable straws reduces the demand for plastic, leading to lower greenhouse gas emissions associated with plastic production and disposal.
• Safety and hygiene: Biodegradable straws provide a safe and convenient alternative for situations where reusable straws are not available or practical.

What Are The Different Types of Biodegradable Straws?

Businesses and consumers have a choice of multiple plastic straw alternatives, from reusable straws to biodegradable straws to compostable straws. Let’s compare some of the best eco-friendly straws that can be used instead of plastic.

PHA Straws

Polyhydroxyalkanoate (PHA) is a biodegradable thermoplastic produced from renewable resources such as cornstarch, sugarcane, and canola and soy seeds. Usually beige or tan in color, PHA straws resemble plastic straws, can withstand high temperatures and are FDA-approved for food service. Compared to paper straws, PHA straws are more versatile and have a longer shelf life, making them a more sustainable and durable option for restaurants and other food service outlets.

PHA Straws Pros

• Biodegradable in industrial composting, home composting, and marine environments
• Made from renewable sources and sustainable
• Durability performs and looks like plastic
• Lots of color, size, and style options

PHA Straws Cons

• Most expensive option in the market
• Limited supply
• Recycling programs for PHA materials are limited
• The degradation time of PHA materials varies depending on the conditions

PLA Straws

Polylactic acid (PLA) is a critical innovation in plastic alternatives. PLA straws are an eco-friendly alternative to traditional plastic straws. PLA is a bioplastic made from natural resources like agave, cornstarch, or sugarcane.

The process of making PLA straws involves a delicate balance of temperature, pressure, and chemistry to turn these raw materials into a sturdy, flexible, and environmentally safe product. Once heated, the material is molded into straw-shaped tubes and cut to size. The result is a product that can serve the same function as traditional plastic straws while reducing the environmental impact caused by non-biodegradable plastics.

PLA is biodegradable under certain conditions. PLA straws cannot be sent to landfills as they require high temperatures to break down. Proper disposal and efficient biodegradation of PLA require industrial composting.

PLA Straws Pros

• Biodegradable
• Made from renewable sources
• Durable
• Sustainable
• Performs and looks like plastic
• Lots of color, size, and style options

PLA Straws Cons

• Will not biodegrade efficiently in a landfill
• Requires industrial composting

Paper Straws

Paper straws have gained popularity due to their biodegradable nature and eco-friendliness. Unlike plastic straws, they do not harm the environment and can be easily disposed of with regular trash or compost. Paper straws are a viable, cost-effective solution to reduce plastic waste and are significantly more sustainable.

Paper straws are made from FDA-approved food-grade paper and do not contain BPA plastics; however, use cases and durability are considerations. Paper straws will get soggy if left in liquid, and some consumers don’t like the feel of paper in their mouths.

Paper Straws Pros

• Degrade faster than plastic straws
• Biodegradable, safe and toxin-free
• Inexpensive
• Availability in various designs and colors

Paper Straws Cons

• Becomes soggy in liquid
• The majority contain chemicals known as poly- and perfluoroalkyl substances (PFAS) that don’t break down in the body or the environment
• Food-contaminated paper straws are non-recyclable
• They can be just as energy-costly to produce as plastic straws

Agave Straws

Agave straws are known for their sturdy and natural composition. They’re made from a fiber produced from FSC-certified waste fibers from the agave plant. Using waste materials with no other purpose means we are upcycling plant waste and turning it into something useful.

The primary purpose of agave is to produce Tequila and Mezcal, an industry that uses quite a lot of the plant but leaves behind massive amounts of unusable waste. Turning that waste into products like straws and other single-use food packaging products is an excellent way to solve both problems—finding a durable, sustainable alternative to bioplastics and reducing the waste left behind by beverage alcohol manufacturers.

Agave straws are sturdy and long-lasting, making them a durable and sustainable alternative to plastic. Agave straws are non-toxic and biodegradable making them ideal for food service and hospitality industries that prioritize sustainability and customer demand for eco-friendly options. They are guaranteed to break down by 95% in the first 180 days in an active landfill, making them a superior choice for the environment over plastic straws.

Agave Straws Pros

How to Dispose Biodegradable Straws Correctly

Not all biodegradable straws are the same, nor can they be disposed of similarly.

For example, paper and agave straws are biodegradable in landfills while straws made from bioplastics like PHA and PLA require high heat to break down and must be disposed of through an industrial composting program.

To help you decide what type of biodegradable straws are best for your needs, consider how you will dispose of them. 

Biodegradable vs. Compostable vs. Marine-Degradable

Although the terms “biodegradable,” “compostable,” and “marine-degradable” sound the same, they actually react differently when disposed of:

• Biodegradable straws break down naturally into simpler compounds over time, typically within a few years, when exposed to environmental conditions like moisture, heat, and microorganisms. Because they’re made from renewable resources, biodegradable straws reduce plastic waste accumulation in landfills and oceans, helping mitigate pollution.
• Compostable straws are designed to degrade in composting facilities under controlled conditions within a specific timeframe with the aim of breaking down into nutrient-rich compost. These plant-based straws divert waste from landfills and can enrich soil when properly composted, contributing to a circular economy.
• Marine-degradable straws can break down in marine environments where they disintegrate into harmless substances without impacting marine life. Designed to combat plastic pollution in oceans, these straws are made from materials that break down in saltwater environments.

Home-Compostable vs. Industrial-Compostable Straws

Compostable straws, such as those made of bamboo, paper, or sugarcane, are classified as those that can decompose in a home compost bin or straws that require disposal in an industrial compost facility.

Under normal conditions, home-compostable straws can break down in home composting systems. As long as the heat, moisture, and microorganism conditions are similar to traditional composting, these straws will decompose effectively, although over a longer period of time.

Industrial composting facilities deal with a broader range of compostable products in controlled environments. Industrial-compostable straws require higher temperatures and microbial activity in industrial composting settings to fully break down within a shorter time frame.

The History of Biodegradable Straws 

From a necessity to a minor convenience, biodegradable straws were created from a long history of straw-making:

• 3,000 B.C.: Ancient Mesopotamians used 3-foot-long drinking straws from various materials, including gold, silver, or wood, to drink brewed beer from large vats that were too heavy to move.
• 1500s: Argentinians used metal straws invented specifically for drinking yerba mate—a whole-leaf herbal tea. It contained a large hollow circle at the bottom with holes to strain tea leaves. This reusable drinking straw is still used today.
• 1800s: Rye grass straws were used for drinking spirits but left an unpleasant flavor in beverages. Inventors created drinking straws out of manila paper to address the flavor issue. They eventually transitioned from using glue to wax-coated manila paper, which led to the creation of the modern paper drinking straw.
• 1930s: Paper straws were widely used, and soon the first bendy straw was created. These straws were marketed during the polio era as a hygienic solution for communal beverage consumption and to feed sick patients easily.
• 1940s to 1980s: Despite the initial success of paper bendy straws, they faced challenges due to production limitations, and people were dissatisfied with straws losing their shape in liquids. Multiple companies started mass-producing plastic straws to replace paper straws, and new products like the Krazy Straw were invented.
• 1990s to 2000s: As awareness of plastic pollution and fossil fuel depletion grew, researchers explored biodegradable materials like cornstarch and polylactic acid (PLA) for sustainable alternatives. Early bioplastic prototypes from plant-based polymers laid the foundation for today’s bioplastic straws.
• 2010s: Plastic pollution awareness increases among the public. An internet video showing a sea turtle with a plastic straw stuck in their nostril goes viral, sparking global outrage and calls for plastic straw bans. Many campaigns took off. Countries like France and businesses such as Starbucks and McDonald’s took steps to ban or reduce plastic straw usage.
• 2020s: More cities and countries, like England and Canada, ban single-use plastics, including plastic straws. Most people worldwide support banning single-use plastics, and large corporations voluntarily switched to eco-friendly alternatives.
