Biodegradable resins are capable of playing a key role on our path to sustainable plastic production. While they will never completely eliminate the problem of plastic waste (since they are not suitable for all product applications), biodegradables can nevertheless be an important tactic in reducing pollution and waste in some instances.
The ability to compost single-use products like food service ware and packaging items, such as bags and films, ensures that plastic waste won&#;t remain on the planet for hundreds of years, reduces the amount of methane gas emitted from landfills and could help to prevent humans from needing to designate ever-larger parcels of land for trash disposal. According to the United Nations Environmental Programme (UNEP), between 22 and 43 percent of plastic consumed globally finds its way into landfills. Biodegradable resins could help to bring this number down, reducing one of the longest lasting impacts of our plastic use.
Because plastic waste has a tendency to end up in our parks, waterways and other sensitive ecosystems, it&#;s important to verify when shopping for biodegradable resins that &#;biodegradable&#; does not simply mean the capability to disintegrate into pieces invisible to the naked eye. True biodegradability means the ability to be broken down by bacteria of other organisms. Since the rise of green consumer preferences and government regulations have many companies working to improve their environmental footprint, it&#;s important to verify that a material meets industry standards for actual biodegradability, as well as biobased content.
From pill bottles and life-saving medical equipment to business-essential tools and household appliances, there are uncountable numbers of products that manufacturers make out of plastic. Polymers are truly exceptional materials.
While plastic will likely always have a place in our lives, it&#;s clear that our over-reliance on it has severely impacted our planet. Thankfully, biodegradable resins (also known as biopolymers and bioplastics) may provide a sustainable solution to this issue.
However, in contrast with synthetic resins, biodegradable resins present some unique challenges. If you&#;re interested in how biodegradable resins could work for your products, this piece is for you. In it, Anova Innovations will explore:
People produce about 400 million tons of plastic waste every year. Half of all of this plastic is designed for single-use purposes, meaning it&#;s discarded after one use.
For the past five decades, the rate of plastic production has grown faster than any other material production. At our current rate, the global production of plastic is forecasted to reach 1.1 billion tons by . That&#;s like producing eight Empire State Building&#;s worth of plastic a day. Despite recycling efforts, roughly 98 percent of single-use plastic products are still made from &#;virgin&#; fossil fuel feedstock.

In search of a more sustainable option, many manufacturers are trying to identify how they can incorporate biodegradable plastic into their production processes. As their ideas transition from theoretical to practical, the biodegradable polymer market is poised to experience significant growth.
The global Biodegradable Polymer market reached $7.25 billion in and is anticipated to reach $23.65 billion by . This equates to a staggering compound annual growth rate (CAGR) of 14.4 percent between and .
This growth will be primarily due to biodegradable polymer use in water bottles, food containers, packaging, and medical supplies. Additionally, some governments are combating single-use plastics by creating initiatives and bans that encourage biodegradable plastics.
For instance, the United Kingdom has a wide variety of bans on plastic stirrers, drinking straws, plates, and cutlery. Likewise, St. Kitts and Nevis have a &#;Plastics Be Gone&#; campaign that aims to reduce single-use plastics by 30 percent over the next five years. There are also eight states that have outlawed single-use plastic bags.
There is an expense for manufacturers to transition from synthetic plastics to biodegradable resin. But surveys suggest that the majority of Americans are willing to pay more for sustainable products.
Currently, the biopolymers gaining the most prominence are those made from cellulose, chitosan, starch, and proteins. Environmentalists and manufacturers alike are now looking at how to source these materials from the food, pharmaceutical, and agricultural industries, which produce all of them as a byproduct of their manufacturing processes.
As biodegradable polymers become more widely adopted, people will realize a myriad of benefits. For instance, bioplastics:
Unfortunately, bioplastics don&#;t come without a few disadvantages. Most notably, they have low-to-poor mechanical properties, meaning they don&#;t perform as well as their synthetic counterparts when in a load-bearing application. Due to most bioplastics&#; limited mechanical properties, there is also a smaller range of uses.
Interestingly, the same thing that makes bioplastics environmentally friendly is the thing that makes them challenging to work with. With rapid degradation rates, the use cases for bioplastics become slightly more limited to single-use and limited-use applications. The high hydrophilic capacity of biopolymers also restricts the strength of products.
Due to these properties, many manufacturers have found it challenging to integrate bioplastics into their current processes. Additionally, with the price of bioplastics being significantly more expensive, they&#;re hesitant to experiment.
However, with the right molds, you can seamlessly replace synthetic plastics with biodegradable resins. In order to ensure improved product surface quality, better filling of the mold cavity, and improved cycle time, you need to use a mold with conformal cooling channels. These channels optimize the heating and cooling process to ultimately produce better products, even when using biodegradable resins.
Additive manufacturing (AM) is a process that can create complex molds by adding layers of material, such as steel, metal, or plastic. Nearly every step of this process is computer-aided and automated in order to produce highly intricate parts.
When using traditional subtractive manufacturing practices, manufacturers must mill and drill straight-line water cooling channels to cool the part. Now, by building molds layer by layer, AM provides the opportunity to create curved channels that follow the part&#;s geometry. With improved cooling abilities, AM opens up new opportunities to leverage the power of bioplastics.
