How to Dispose of Roundup Weed Killer?

Depending on the function and the weed they are meant to control, weedkillers are all produced per very tight standards and regulations.

Roundup is a common weedkiller used in household gardens worldwide. It comes in two forms: an aerosol that needs to be diluted with water before usage, and a concentrate.

Roundup is marketed under several names, and needs to be properly disposed of, since it can harm humans and the environment.

Why Is Roundup Weed Killer Harmful?

Because it includes the herbicide glyphosate, Roundup can harm the soil in high concentrations, affecting plants for years if it builds up in one place.

Plus, glyphosate makes it extremely toxic to humans and animals. It is an herbicide meant to destroy broadleaf weeds. That said, Roundup can also kill neighboring plants or any other plant it comes in contact with.

Due to its high toxicity levels, it can harm humans, and many individuals are now concerned that it may cause cancer.

Headaches, nausea, exhaustion, runny nose, burning or watery eyes, and skin irritation are all signs of Roundup toxicity.

However, there are more severe symptoms of roundup poisoning as well. These include red blood cell breakdown, breathing issues, and liver and kidney damage.

Due to its ability to destroy flora, it is also hazardous to the environment. This flora is essential for animal habitats. It can also enter waterways, where it may harm fish and other wildlife.

When To Use Roundup?

In general, weeds can be eliminated at any time of the year. However, the optimal application period is when weeds actively develop as it speeds up Roundup’s absorption.

It is especially true for systemic and selective weedkillers, which depend on plant activity to be effective.

Furthermore, apply Roundup in calm weather to reduce the risk of the weedkiller drifting onto other plants.

Applying Roundup with a Sprayer

Use a sheet of card to screen plants from the application, to protect the ones you wish to maintain.

Always read the label to determine whether a watering can or a sprayer is the best application technique for Roundup.

To prevent it from spreading onto other plants, wait until treated areas are completely dry. This will allow you to avoid spreading the weedkiller with your shoes.

Applying Roundup with a Can

Of course, you can use a sprinkle bar to control where you apply your Roundup.

However, you can easily cause unintentional harm to other plants during routine watering. Hence, keeping a separate watering can would be wise.

In fact, a watering can is a must here. It helps you control the amount of Roundup applied to your plants. And this technique will drastically lower your chances of applying more than you actually need.

Precautions While Using Roundup Weed Killer

Below are a few safety precautions to consider when applying Roundup to your plants.

  • Always read the label on your roundup bottle and follow the instructions to the “T”, to avoid harming yourself and the environment.
  • Always be careful when using weedkillers.
  • Check if the product can be used with a sprinkler system, watering can, or pressure sprayer. Also, determine the time of the year the weedkiller is most effective.
  • Combine the Roundup with the amount of water mentioned on the label. Don’t try to add more product than needed.
  • Apply it to your plants evenly. But, avoid under or over-spraying.
  • Don’t spray it in bright sunlight.
  • Apply it to your plants in a cooler climate to avoid scorching.
  • After each use, thoroughly rinse your sprayer or water can. Add a few drops of detergent, then run clean water through the nozzle.
  • Whatever you do, never rinse weedkiller applicators down the drain.
  • Keep pets and kids away when spraying Roundup in your back or front yard.
  • When spraying onto poisonous weeds, such as ragwort, remain cautious and safely dispose of it. This weed is entirely poisonous.

Tips To Safely Dispose of Roundup Weed Killer

Roundup is typically used on farms and lawns to kill weeds. However, the best thing about this weedkiller is that you can purchase it from your local gardening store.

Some people might still have a few bottles of Roundup lying around their house from previous weedkilling sessions. So, what will happen to these empty containers?

After all, they still contain chemicals that can be dangerous. In fact, it is a health hazard for anyone who comes in contact with the leftovers.

Depending on the number of bottles, there are many ways to get rid of them. However, whatever you do, never flush it down the toilet.

Roundup is poisonous and might end up harming the environment. So, never flush it, pour it down the drain, or empty the container into a trash can.

Always follow the manufacturer’s directions on the label before disposing of any chemicals, including Roundup. Most weedkillers typically come with disposal instructions.

So, on that note, here’s how to dispose of Roundup properly:

Use Packing Peanuts to Thicken It

The safest approach to get rid of Roundup is to use packing peanuts. The best thing is, you can purchase these packing peanuts in bulk from a moving supply provider.

Once you have them ready, pour the leftover Roundup on them. The packing peanuts will quickly soak the weedkiller and form a clump. After that, store the clump in a plastic bag.

Finally, dispose of this clump of Roundup by contacting your local waste management service. You can also contact the relevant state environmental agencies to dispose of it.  

Use Cat Litter to Thicken It

Roundup can also be disposed of by combining it with cat litter. It will thicken up when applied to cat litter, making it safer to dispose of.

Roundup can be disposed of relatively easily using this manner. However, exercise caution to avoid unintentional digestion if you have children and pets.

The directions are the same as using packing peanuts. Apply the leftover Roundup to the cat litter. Then, once a clump is formed, dispose of it at your local waste treatment facility.

Take It Directly to a Hazardous Waste Collection Center

If you don’t know how to utilize the aforementioned methods, you should dispose of Roundup directly.

The first thing to do is gather all the leftover cans and containers. Then, simply place them in a carton and take them to your local hazardous waste collection center.

In fact, The Environmental Protection Agency (EPA) claims that this is the safest method for getting rid of Roundup.

Your local hazardous waste collection center knows precisely what to do with it. They will safely dispose of it and prevent it from being dumped in landfills.

Health Hazards Related to Roundup

The use of Roundup is currently a hotly contested issue. According to research, the active component in glyphosate in Roundup may raise the risk of various health issues.

On the other hand, this weedkiller has long been regarded as one of the safest herbicides on the market. However, glyphosate is not the only ingredient in Roundup.

It also has additional chemicals, contributing to its effectiveness as a weed killer. Some of these components—known as inerts—might even be kept under wraps by the manufacturer.

Thus, studies demonstrating the safety of glyphosate might not apply to the entire Roundup mixture.

Some of the health effects of Roundup are listed below:

Roundup May or May Not Lead to Cancer

The World Health Organization (WHO) classified glyphosate as a possible human carcinogen in 2015.

Simply put, this indicates that glyphosate has a risk of causing cancer. However, although it has been linked to malignancies in research on mice and rats, there is little data on humans.

In fact, the studies that are available mostly focus on herbicide users.

One or two of these studies connect glyphosate to non-Hodgkin’s lymphoma, a malignancy that develops in white blood cells called lymphocytes.

However, some studies have not discovered a relationship. Extensive research involving more than 57,000 farmers showed no connection between lymphoma and glyphosate usage.

But it should be noted that some of these researchers have financial links to the American agrochemical company Monsanto. Therefore their findings might be biased.

It May or May Not Affect Gut Bacteria

Your gut is home to hundreds of different kinds of microorganisms, typically different types of bacteria. Some of these are beneficial microorganisms that are vital to your health.

These bacteria can get affected by Roundup. The glyphosate found in Roundup blocks the shikimate pathway. It is crucial for both microorganisms and plants.

Further, glyphosate has also been discovered to disturb healthy gut microbes in animal tests.

Other Side Effects of Roundup

The biggest likelihood of negative health effects of Roundup appears among farmers and people who deal directly with this weedkiller.

Glyphosate residues have been discovered in agricultural workers’ blood and urine, particularly those who do not use gloves.

According to other research, many Sri Lankan farm laborers are suffering from chronic kidney illness, which may partly be caused by glyphosate.

However, further research needs to be done on these health impacts. Remember that research on farmers who use the herbicide often might not apply to everyone.

For example, this research doesn’t apply to people who consume it in trace levels through genetically modified food products (GMO).

Wrapping Up

There is no doubt that Roundup is a hazardous herbicide. If not disposed of correctly, it can lead to various environmental and health issues.

Therefore, it is crucial to understand how to dispose of it properly. So, always take the necessary steps to ensure the safety of your family and the environment.

Therefore, rinse your hands with warm water if you come in contact with Roundup. Furthermore, if you ingest it accidentally, don’t panic; visit your doctor immediately.
