Can You Pour Milk Down The Drain (If Not, What Should You Do)

Milk spoils pretty quickly. We all know this. We’ve all experienced it ourselves.

Unless you buy yourself long-life milk, you have to make use of your milk quickly in order to taste it at its absolute best.

Can You Pour Milk Down The Drain

It’s likely that you’ve had to dispose of bad milk before, but you weren’t sure how to do it, or you weren’t sure that you did it the right way.

It’s not always easy to know what to do with spoiled milk, hence why we are here together today.

There aren’t many official sources out there that will definitively answer the questions of what to do with our spoiled milk, so it can be hard to know exactly what to do.

If you have bad milk in your fridge and you want to dispose of it quickly and properly, then take a look at this handy guide, as we find out once and for all what you should do with spoilt milk!

Can You Pour Milk Down The Drain?

No. You should absolutely avoid pouring any amount of milk down the drain. This might seem surprising to some, but it should definitely not be done, where possible.

Pouring milk down the drain causes it to end up seeping into the environment around you. This is bad because of how milk decays. 

As milk decays, its components slowly begin to break down and the milk begins to separate.

This process requires a massive amount of oxygen to take place, so any small organisms within the vicinity of decaying milk will be deprived of the oxygen they need.

Though small, the impact on the environment is considerable enough for the act to be considered taboo.

Can You Pour Expired Milk Down The Toilet?

Upon first hearing that you should not dispose of milk down the drain, you likely found your brain going to the next best option. The toilet.

However, this is equally as bad, as the drain and the toilet will still lead to the same destination: your local sewers.

From here it is able to spread out into the local ecosystem and wreak havoc with its oxygen-greedy decaying process.

Why Should You Not Dispose Of Spoiled Milk Down The Drain?

As well as the potential environmental impact of such an act, pouring spoiled milk down the drain can cause fatty deposits to develop in your drains and in the local sewer system.

Why Should You Not Dispose Of Spoiled Milk Down The Drain

This is because, as milk begins to spoil, its elements begin to separate, so the fat will clump together, and when this fat dries up it can become incredibly solid and hard to remove. 

This could cause havoc on your water system at home, which can be costly to fix, and even worse it could lead to larger fatbergs in your local sewer system, which can cause smelly and disastrous blockages for all people in your local area!

How Can You Dispose Of Milk?

Since you know you shouldn’t pour your milk down the drain, you’re likely wondering what you can do with your unneeded milk. As it turns out, there are quite a few options available to you. 

If you have a number of house plants, or a small number of plants in your backyard, you can use old milk to water them! Yes, you heard that right.

Milk is very high in water content, so of course, plants can thrive wonderfully from it.

Milk also has plenty of calcium, which helps to build strong and protective cell walls to protect the soft inner section of a plant. 

Spoiled milk can be processed to create a large number of useful things. Allowing it to decay naturally lets milk turn into a natural fertilizer that is perfect for helping your plants in your yard to thrive.

However, you should make sure not to pour out unspoiled milk into your backyard. This is because it can be harmful to the environment.

How Can You Dispose Of Milk

When milk decays it makes use of a lot of oxygen, which can cause small creatures to be deprived of the oxygen that they need!

You can even donate unspoiled milk. Many people choose to dispose of milk that is otherwise perfectly fine simply because they no longer have a use for it.

This is a shame, because it can be used by many other people that do need it!

You can also donate spoiled milk to be converted into soil and compost, so that every drop goes to good use in a way that doesn’t harm the local environment.

Why Does Milk Spoil So Quickly?

Milk naturally contains a lot of bacteria. This is perfectly natural and the amount of bacteria within it is safe to consume.

However, this bacteria very quickly gets to work on converting the lactose in the milk into glucose. During the conversion process, lactic acid is produced.

When lactic acid mixes with casein, it begins to create that horrible curd that we recognize from milk that has gone bad.

This is how milk is able to spoil so quickly once opened, and also explains why so much milk has to be disposed of so regularly.

Conclusion

If you’ve got excess milk in your fridge, or you’ve got any milk that is spoiled, please make sure not to dispose of it down your drains.

This also includes your toilet, or any other drains located within your home. It can wreak havoc not only on your drains, but also on the local ecosystem.

Instead, you can donate extra unspoiled milk to those that do need it, or give spoiled milk to those that can convert it to soil and fertilizer. 

Frequently Asked Questions

What Can You Use Curdled Milk For?

Although curdled milk may taste and smell rather foul, the lactic acid found within it can be used to help treat certain conditions, such as appendix inflammation and colon infections, just to name a small few. 

You could even use curdled milk to create your own cheese!

Is It OK To Eat Curdled Milk?

Many recipes for hot drinks or hot foods require milk to be made. When milk is heated up it naturally begins to rapidly curdle, so whenever you use milk in a hot recipe, you are already eating curdled milk.

So it’s safe to say that, yes, it is okay to eat curdled milk. However, curdled milk can taste very bad, so it isn’t recommended to eat it alone.

How Long After Drinking Spoiled Milk Will I Get Sick?

You are not guaranteed to experience any symptoms of sickness from drinking spoiled milk. If you only drink a small amount, all you will experience is the nasty taste of the milk!

However, if you were to consume more, you may end up developing vomiting or painful diarrhea up to 24 hours after consumption.
