Pasta is a very commonly eaten food in households all over the world. With any type of pasta, there is a good chance you are gonna mix it with different food items and meal types. When it comes time to discard the pasta, you might not be sure what to do.
No matter how much you eat or how often you eat it, there will inevitably be some pasta waste. Whether it is uncooked pasta that went stale in the cupboard or was nibbled on by a rodent or two, or it was part of a pasta dish with dairy products and cooked pasta, you will need to get rid of it. Fortunately, composting pasta is easy; read below to see how to start the decomposition process.
Can Pasta Break Down in Compost Bin?
Pasta will break down in the compost pile, but it will need to be mixed with both carbon-rich materials and high-nitrogen green material. Coffee grounds and vegetable scraps mixed with dry pasta will break down quickly in a compost bin. Wet pasta that has been cooked will need additional paper and dry goods to improve compost structure. Doing this correctly will ensure your pasta breaks down nicely.
If you are tossing dry pasta on its own, there is not much else to worry about, but sometimes cooked pasta will have sauces and be composted with other starchy foods like garlic bread. If you will be adding pasta with other compostable materials, you may need to make adjustments to the moisture and supplementary nitrogen-rich materials.
Types of Sauces with Pasta Effects on Compost
Cooked pasta is very rarely composted plain and will always have a sauce and some other ingredients mixed in. While all these flavors make for a delicious meal, it can be hard to know if it will lead to healthy compost in one of our compost tumblers. That really depends on what it’s made of.
Cheese and meat pasta sauce can be a bit of a problem if you are trying to keep unwanted pests out of your leftover pasta. Usually, organic matter from animals and especially dairy products, are not great for the composting process in home compost bins because the smell can attract wild animals. Adding other compostable materials like wood shavings and grass clippings can help speed up the composting process and remove excess moisture.
Most of the time, mushrooms and veggies will cause no issues being added to the rest of the leftover pasta and starchy foods. Oily sauces and creamy sauces, as well as pasta with loads of sauce, should be added slowly. There are some herbs and spices like salt and red pepper that should be added in moderation, but the amount of seasoning used for food is unlikely to harm a compost pile.
Can You Compost Uncooked Pasta?
Dumping starchy foods like uncooked pasta, bread, rice, and potatoes into the compost is fine as long as it’s not added in huge quantities. If you do have a lot of compostable materials to add at once, you can break it up into smaller pieces and spread them out before adding them. When composting dry pasta, you will need to add additional moisture to make sure it breaks down.
Adding uncooked pasta alone will not be the greatest compostable material and will make lousy finished compost. People often add leaves, kitchen waste, shredded paper, and other pieces of home and food items for better composting results. Meat and dairy products shouldn’t be added with your uncooked pasta as they will not help it break down and may attract rodents and other pests to your composters.
Can You Compost Cooked Pasta?
Cooked pasta is an excellent compostable material and leaves very little residue behind once it is broken down. Like other starches, rice, and bread, the bit of moisture in these edible items will be enough for them to start to decompose. Usually, however, cooked pasta is not tossed on its own but with other edible items.
Some precautions are needed while composting dairy components, and take care with meat and other animal products when composting pasta. It’s a good idea to try to separate the pieces of pasta from cheesy sauces, creamy pasta sauce, and other heavy leftover pasta sauces, as well as other vegetable trimmings and food scraps.
Dump everything in small batches in different areas of the outdoor compost pile to prevent moldy food and huge piles of rotting pasta scraps. Mix in dry materials like shredded leaves and tree branches to improve air circulation and improve the moisture balance of compostable materials.
How To Compost Pasta
While there aren’t too many issues with composting pasta, sometimes composting lots of it can be tricky. Notwithstanding the whole tomato sauce business can be messy and introduce acids to your soil, a wide variety of problems can be solved by following the steps below. The information you need to compost both wet and dry pasta safely will give you an extra layer of protection from poor aeration and pesky pests.
|Raw or Cooked
|Choose the correct bin for cooked or raw pasta
|Makes it easier to compost correctly and add the correct additional materials
|Add a small amount at a time relative to how big your compost pile is
|Less stress on the compost and better end-soil product
|Remove sauce and other table scraps from the pasta and deal with them separately
|Helps deal with different levels of moisture and potential non-compostables.
|Tear, break, or cut pasta so that it is easier to break down in the compost
|Faster decomposition and fewer anaerobic pockets
|Add in Batches
|Put the pasta into the compost a little at a time if discarding a whole pot or lots of dried pieces
|Less than one type of material pile high in the compost where it should attract pests or stink
|Add Additional Materials
|Green wet materials or dry carbon materials should be added
|Wet material will help dry pasta break down, and dry material will help wet pasta have structure and not collapse into a goopy mess
|Turn the soil so that all of the pasta and added materials are covered with compost and soil
|Helps soil bacteria get to the pasta faster and can keep pests from detecting it as easily
|Add water if the pile is dry, and add more brown materials if the heap is wet
|The right amount of moisture helps bacteria grow quickly and speeds decomposition without becoming stinky and soupy
|Cover and Protect from Pests
|Bury with more soil or cover the bin with a lid or netting
|Keeps insect and rodents pests from digging in your compost, contaminating your pile, and taking your pasta
Separate the wet pasta from everything else and put it off the side. If you can remove some of the oily sauce and meats or other animal food scraps, do so. Other compostable materials should be added with wet pasta to increase the nutrient content of the finished soil. If you add tons of food waste at once, you will have to deal with all sorts of pest problems, so bury it deeply.
Most of the dry pasta can be added to the compost but try to avoid adding it with cooked rice or other starchy compostable materials. Bread in compost piles can also attract similar unwanted visitors that could ruin the entire process of composting. Take special care to break up pieces of dry pasta and mix them with yard trimmings and other materials in composting bins. For extra security, use a lidded container.
Will Worms Eat Pasta?
Worms will eat pasta and any other of your unwanted leftovers. Oily materials in composting can be bad for worms, so try to add that in very small amounts. While worms will break down pretty much everything, we put in there some spices like red pepper flakes are delicious on pasta but not great for your worms.
Many times a staple food like pasta will have tomatoes or tomato sauces mixed in to enhance the flavor. While a few tomatoes aren’t going to lead to any worm bin issues, too much can create an acidic environment and upset the worm’s gut and digestion. If worms don’t want to eat, then your waste won’t break down quickly. If you will be adding tomato sauce, then add lots of dry brown material to help balance the acidity.
When putting grains and starches into the worm bin, make sure to bury them. These types of food can be harder to attract bacteria and need extra contact with soil to speed up the process. Burying cooked and uncooked pasta can also deter pests who are looking for a quick and easy meal. Once it’s under the surface and safe, worms will make quick work of your composted pasta.
