HIGHLY ACIDIC FOODS Citrus fruit, tomato products and pickled food products can do harm to your compost. High acidity can actually kill the good bacteria that helps break down the material in your compost pile.
Fruit and Vegetable Scraps
It's recommended to cut scraps and leftovers down to around two-inch chunks or less so that they decompose more quickly. Some fruits and vegetables that you should compost with caution are those with high acidities, such as citrus fruits, pickles, and tomatoes.
Most fruits—from apples and bananas to pears, grapes, and berries—provide compost with plenty of nutrients that will enrich your soil. Typically most varieties are safe to add, depending on the type of composting system you have at home, though there are some fruits that are better for composting than others.
Don't put diseased plants, pet droppings (apart from chook manure), cooking fat, glossy paper, weeds with seeds, treated timber and large branches in your compost bin. Some gardeners say you should avoid adding meat and bones unless you have a larger compost system.
Composting Don'ts
Don't add fish, meat, dairy products, bones, baked goods, fatty foods or grease to your compost pile. These food scraps do not easily decompose and may attract animals. Don't use diseased plants or plants that are toxic to other plants.

Every single part of an onion is 100% compostable!
You may have heard otherwise, and yes, there are a few things to look out for if you want to add them to a worm bin, but no worries, onions can make their way to your compost bin, just like your other kitchen scraps!
Can You Compost Eggshells? Egg shells are an excellent addition to a compost pile, as they provide calcium and other key nutrients. Whole eggs, egg whites, and egg yolks do not belong in the compost pile, though. Raw eggs have the potential to carry the bacteria Salmonella.
Without question, banana peels are compostable. Composting banana peels is as easy as simply tossing your leftover banana peels into the compost. You have the option of tossing them in whole or chopping them into smaller pieces. However, be aware that they will take longer to compost if they are thrown in whole.
Water is one of the four essential ingredients for successful composting. Enough H2O in a pile will help compost microorganisms break down organic wastes. The trick is getting the moisture level just right! Too little, and the microorganisms will struggle to work; too much, and they'll be starved of oxygen.
Answer: You can add moldy food (vegetables and fruits only) to a backyard composting bin anytime. Mold cells are just one of the many different types of microorganisms that take care of decomposition and are fine in a backyard bin. If you're using a worm bin, you have to be a bit more careful.
Veggies and fruits are the quintessential compostable foods. You can compost them in any form: scraps and peels, raw or cooked, and even when rotten. Before you toss, make sure you're not wasting these completely edible food scraps.
Compost It!
Composting lemon peels and other citrus fruit is a simple way to reduce food waste. Even though citrus fruits are very acidic, there are great benefits to adding them to your compost pile, such as: The strong scent deters pests and animals.
You can compost every part of a pineapple. However, the core is fibrous and tough, so cut it into small pieces before adding it to your compost pile. Cutting the pineapple core increases its surface area and makes it decompose faster.
Yes, you can compost strawberries. They rot down quickly in a compost heap – they're a “green” (even when they're red ;)), so if you've got a lot to get rid of, add them alongside “browns” (like newspaper, egg boxes or straw) to help soak up/take advantage of the excess moisture.
Yes, you can compost uncooked rice, but again, you must be ready to deal with a few challenges. For one, uncooked rice is a staple food and a grain at that. It's pretty solid too, which means it'll take a significant amount of time for it to break down.
Do tea bags break down in compost? Paper tea bags are safe to compost. In fact, they will break down just as quickly as the tea leaves inside of them. On the other hand, plastic tea bags are not biodegradable.
Bread can be composted!
The concern is that they may attract rodents and other pests. However, bread has been cold composted without problems when buried the in the middle of the bin, or heap, and covered with a layer of “Browns” e.g., dry leaves, sawdust, shredded paper and then with a layer of soil or manure.
In short, the answer to “Can you put coffee grounds in compost?” is yes. Not only can you add coffee grounds to any composting setup, but you should. Coffee grounds are beneficial for your soil, and they're one of the easiest food wastes to compost.
Can I place used paper towels, napkins, and tissue in my compost cart? Yes, absolutely. These items can be composted even if they are wet or stained with food, vegetable oil, or grease. Please do not place paper towels, napkins, or tissue into the recycling!
Weeds have many nutrients so they are a great addition to the compost pile, but you do not want compost filled with viable weed seeds. The best time to take care of weeds is when they are small and have not established deep roots or seed heads (easier to pull, too, especially if ground is still moist).
Well, yes, cheese is compostable, although be very careful when doing it. Dairy products like cheese are some of those foods that most traditional composters will advise you to avoid. The main reason for this is because animal food waste is considered to attract pests.
Brown paper bags can be easily composted, and they offer an energy-efficient way to gain environmental value. But it is important to use a mix of green materials and brown paper bags. Plain brown paper, dead leaves, and cardboard are used in combination with kitchen waster and grass clippings.
Turning once a week or once every two weeks had generally lower decomposition rates. To maintain a thermophilic pile (pile with high heat), it should be turned every three to four days, or when the temperature drops below 104 F. However, if most of the material has been decomposed, less frequent turning is adequate.
What about shredded newsprint? Except for colored and glossy paper, which might contain some toxic heavy metals, newsprint and other paper is safe to use as mulch or in compost. In fact, one study revealed that paper had less toxic material than straw or grass!
