Composting with kitchen scraps: what can and can't be composted

Composting is a great way to reduce waste and create nutrient-rich soil for your garden. By recycling organic materials, such as kitchen scraps, you can divert waste from landfills and contribute to a more sustainable lifestyle. However, not all kitchen scraps are suitable for composting, and it's important to know what can and can't be composted to ensure a successful composting process.

In this blog post, we will discuss the kitchen scraps that can be composted and those that should be avoided. We will explore the benefits of composting, including how it helps reduce greenhouse gas emissions and improves soil fertility. Additionally, we will provide tips on how to properly compost kitchen scraps, including the right balance of carbon-rich and nitrogen-rich materials, as well as the ideal conditions for composting. With this information, you'll be able to confidently start composting and make the most of your kitchen waste.

Fruit and vegetable scraps are compostable

When it comes to composting with kitchen scraps, fruit and vegetable scraps are an excellent addition to your compost pile. These scraps are rich in nutrients and provide the necessary organic matter to create fertile soil.

Some examples of fruit and vegetable scraps that can be composted include:

• Peels from bananas, oranges, and other citrus fruits
• Cores and peels from apples and pears
• Stems and leaves from leafy greens like lettuce and spinach
• Trimmed ends and outer leaves from cabbage and other cruciferous vegetables
• Seeds and pulp from tomatoes and peppers
• Onion and garlic skins
• Carrot and potato peels

These fruit and vegetable scraps will break down easily in your compost pile, providing essential nutrients for your plants.

However, there are some kitchen scraps that you should avoid composting:

• Meat and dairy products: These can attract pests and produce unpleasant odors.
• Oily or greasy foods: These can slow down the composting process and create a slimy mess.
• Bones: They take a long time to decompose and can attract animals.
• Processed foods: These often contain preservatives and chemicals that are not suitable for composting.
• Citrus peels in large quantities: While small amounts are fine, too many citrus peels can disrupt the pH balance of your compost.

By being mindful of what can and can't be composted, you can create a healthy and productive compost pile that will benefit both your garden and the environment.

Coffee grounds and tea bags are compostable

Coffee grounds and tea bags are excellent additions to your compost pile. They are considered "green" or nitrogen-rich materials, which help to provide essential nutrients to the compost. When added to the compost, coffee grounds and tea bags break down relatively quickly, helping to speed up the decomposition process.

However, there are a few things to keep in mind:

What can be composted:

• Fruit and vegetable scraps
• Eggshells
• Grass clippings
• Leaves
• Shredded paper
• Wood chips
• Straw
• Coffee grounds and tea bags

What can't be composted:

• Meat and dairy products
• Oily or fatty foods
• Bones
• Citrus peels
• Onion and garlic peels
• Processed foods
• Plastic

It's important to avoid adding meat and dairy products to your compost pile as they can attract pests and create unpleasant odors. Oily or fatty foods, such as greasy leftovers, should also be avoided as they can disrupt the balance of the compost pile.

While citrus peels, onion and garlic peels, and processed foods can technically be composted, they may take longer to break down and can attract pests. It's generally recommended to avoid adding these materials to your compost unless you have a well-maintained composting system.

Remember to always mix your compost pile well and maintain the right balance of "green" and "brown" materials. This will ensure proper decomposition and help you create nutrient-rich compost for your garden.

Eggshells can be composted

Eggshells are a great addition to your compost pile as they provide valuable nutrients to the soil. When composting eggshells, it's important to crush them into smaller pieces to speed up the decomposition process. This will also prevent them from taking a long time to break down.

By adding crushed eggshells to your compost, you are providing a good source of calcium, which is essential for plant growth. Calcium helps to strengthen cell walls and prevent diseases in plants.

Composting misconceptions debunked: separating facts from myths

In addition to their nutritional benefits, eggshells can also help to regulate the pH levels in your compost. They are alkaline in nature, which can balance out the acidity of other compost materials.

However, it's important to note that you should only compost eggshells from eggs that have been used for cooking or baking. Avoid composting eggshells from eggs that have come into contact with raw eggs or poultry, as they may contain harmful bacteria.

Remember to rinse the eggshells thoroughly before crushing and adding them to your compost pile. This will help remove any remaining egg residue and reduce the risk of attracting pests.

To ensure that your composting process is successful, it's important to maintain a proper balance of green and brown materials. Eggshells count as a brown material, so make sure to add them along with other carbon-rich materials like leaves, straw, or shredded paper. This will help create a well-balanced compost that is rich in nutrients.

Yard waste can be composted

Yard waste is a great addition to your compost pile as it provides a good source of carbon. Here are some examples of yard waste that can be composted:

• Leaves
• Grass clippings
• Small branches and twigs
• Shrub trimmings
• Flower and plant trimmings
• Weeds (without seeds)

It's important to note that when composting yard waste, it's best to shred or chop it into smaller pieces to speed up the decomposition process.

However, there are certain yard waste items that should not be composted:

• Large branches or tree trunks
• Thorny plants or weeds with seeds
• Plants treated with pesticides or herbicides

These items can take a long time to break down or may introduce harmful substances into your compost.

In summary, yard waste can be a valuable addition to your compost pile, but it's important to be mindful of what you include to ensure a healthy and productive composting process.

Meat, dairy, and oils cannot be composted

When it comes to composting, it's important to know what can and can't be added to your compost pile. While many kitchen scraps are suitable for composting, there are certain items that should never be added. Meat, dairy, and oils fall into this category and should be avoided when composting.

Meat, such as leftover scraps or bones, should not be added to your compost pile. This is because meat can attract pests and create odors that can be difficult to manage. Additionally, the decomposition process of meat can be slow and may not break down properly in a home composting system.

Dairy products, including milk, cheese, and yogurt, should also be kept out of the compost pile. Dairy can also attract pests and can create unpleasant smells as it decomposes. Additionally, the high fat content in dairy products can interfere with the composting process and may result in an imbalanced compost pile.

Oils and fats, such as cooking oil or grease, should not be composted either. These substances can create a greasy layer in your compost pile, which can prevent proper airflow and hinder decomposition. Additionally, oils and fats can attract pests and may result in an unpleasant odor.

It's important to note that while meat, dairy, and oils cannot be composted at home, there are alternative methods for dealing with these items. For example, you can consider using a separate system for composting meat and dairy, such as a Bokashi composting system. Oils and fats can be recycled at certain facilities or disposed of properly in sealed containers.

What is permaculture and how does it contribute to a sustainable world?

When composting kitchen scraps, it's best to focus on plant-based materials. Fruit and vegetable scraps, coffee grounds, tea leaves, and eggshells are all excellent additions to your compost pile. These items are rich in nutrients and will help create a nutrient-rich compost that can be used to improve the health of your garden or potted plants.

Remember, a successful compost pile requires a balance of carbon-rich materials (such as leaves or shredded paper) and nitrogen-rich materials (such as kitchen scraps). By understanding what can and can't be composted, you can ensure that your compost pile remains healthy and productive.

Diseased plants should not be composted

When it comes to composting, it's important to know what can and can't be composted. While kitchen scraps are generally great for composting, there are some exceptions. One important rule to follow is that diseased plants should not be composted.

Diseased plants can introduce harmful pathogens into your compost pile, which can spread to other plants once the compost is used in the garden. To prevent this, it's best to avoid composting any plants that show signs of disease, such as discoloration, wilting, or the presence of pests.

Instead of composting diseased plants, it's recommended to dispose of them properly. You can either seal them in a plastic bag and throw them in the trash or burn them if local regulations allow. This will help prevent the spread of diseases and protect the health of your garden.

Remember, composting is all about creating a nutrient-rich and healthy soil amendment. By being mindful of what you compost and avoiding diseased plants, you can ensure that your compost pile remains a beneficial addition to your garden.
