The market for biodegradable plastic mulch is growing every day as people become increasingly aware of the negative environmental impact of traditional plastics. While many different types of biodegradable mulches are on the market, some last much longer than others. This article will explore the various biodegradable mulches and discuss how long they typically last. We will also provide tips to help you choose the right one for your needs.
What is biodegradable plastic mulch?
The term “biodegradable plastic mulch” refers to a type of plastic mulch designed to decompose in the soil.
biodegradable plastic mulch film is made from renewable resources and biodegrades into carbon dioxide, water and biomass within months to a few years.
In contrast with conventional plastic mulches, biodegradable plastic mulches are made from polymers derived from renewable resources such as corn starch or sugar cane. These polymers can be used to manufacture plastic products that will decompose when they enter the soil.
For example, corn starch can be fermented into lactic acid through anaerobic fermentation. Lactic acid is then polymerized into polylactide (PLA), creating biodegradable plastics such as PLA film bags or water bottles.
Biodegradable and compostable plastic mulch is typically composed of PLA film with additives such as colorants and sunscreens added during manufacturing. The combination of these additives produces a product that performs like regular plastic while also being environmentally friendly because it will eventually break down once it reaches the soil level. Biodegradable plastic mulch is often used in commercial agriculture to help reduce soil erosion and water run-off. It is also popular among homeowners who want to reduce the trash they send to landfills.
Pros and Cons of biodegradable plastic mulch
Biodegradable plastic mulch is a type of mulch that has the ability to decompose. It is made from polylactic acid (PLA) derived from plants such as corn, sugar cane and sugar beets. Biodegradable mulch is also referred to as bio-mulch, compostable mulch or green mulch.
The main benefits of using biodegradable plastic mulch include the following:
1) Composting
It can be composted with other organic materials such as leaves and grass clippings. The advantage of this is that it will allow you to recycle the material instead of sending it off to a landfill where it will sit for years before being broken down by natural processes or buried under more waste materials.
2) Natural look
When compared to traditional wood or plastic mulches, biodegradable plastic looks similar but tends to break down faster than them. This allows your garden bed to look natural while protecting it from weeds and pests by blocking sunlight from reaching the soil underneath it.
3) Affordability
They are often less expensive than other mulches because they do not need replacing after only a few years.
4) Environmentally friendly
Because biodegradable plastic mulches are made from organic materials that are not petroleum-based, they do not contribute to the number of greenhouse gases in our atmosphere.
Cons:
Biodegradable plastic mulch is more expensive than traditional plastic mulch. However, it should last longer than traditional plastic mulch because it will break down over time.
How long will it last?
The answer to this question depends on your application and how much you are using. It is a renewable resource that can be recycled if not composted. The most common type of biodegradable plastic mulch is made of polylactic acid (PLA) derived from corn, wheat or sugarcane waste.
How long will it last?
PLA plastic mulch can last anywhere from a few months to several years, depending on the type of application and environmental conditions. The main factors that affect the longevity of biodegradable plastic mulch include the following:
Temperature: PLA plastic breaks down faster in warmer temperatures than in colder weather. For example, suppose you have a high-temperature environment like a greenhouse or nursery. In that case, your biodegradable plastic will only last about six months while in storage, but could last as long as two years outside in cold weather conditions. Suppose you live in a warm climate where temperatures reach 80 degrees Fahrenheit or more. In that case, your biodegradable plastic will only last about three months in storage, but could last up to four years outdoors when placed under shade trees or other plants provide shade for the plastic.
Other sources of sunlight. Biodegradable mulch will last for about two years if it has no sunlight or water exposure. If there are other sources of sunlight in the area (like an artificial light source), the mulch will only last one year.
Rainfall. The amount of rain that falls in the area will also affect how long biodegradable mulch lasts. If there are periods where there is no rain, then the mulch will last longer than if you live in an area with lots of rainfall throughout the year.
Conclusion
If you’re looking to reduce the amount of plastic in landfills, biodegradable, compostable mulch film might be a good option. It is made from plant-based materials . And it can decompose over time, breaking down into smaller pieces easily removed by soil or water. While biodegradable plastic mulch does have some environmental benefits, it doesn’t last as long as traditional plastic mulch. If you decide to use it, replace it every few years so that your landscape stays healthy and tidy.
