Composting is a great way to reduce waste and create nutrient-rich soil for your garden. But when it comes to composting, some people are unsure about what materials can and cannot be composted. In this article, we will explore whether paper and cardboard can be composted and if there are any restrictions.
Composting for Beginners
If you are new to composting, it is important to understand the basics. Composting is a natural process where organic materials break down into humus, a dark, nutrient-rich soil amendment. By composting at home, you can divert food scraps and yard waste from the landfill while creating a valuable resource for your plants.
There are two main types of composting: hot composting and cold composting. Hot composting involves maintaining a high temperature through frequent turning and proper balance of carbon-rich (browns) and nitrogen-rich (greens) materials. Cold composting, on the other hand, is a slower process that does not require turning and can accommodate a wider range of materials.
Can you compost paper?
Yes, paper can be composted. Paper is made from plant fibers, and these fibers can break down in a compost pile. However, not all types of paper can be composted. Glossy or coated papers, such as magazines or shiny cardboard, should not be composted as the coatings can contain chemicals that may be harmful to plants.
When composting paper, it is best to shred or tear it into small pieces. This will help speed up the decomposition process. Avoid adding large pieces of paper as they may take longer to break down. It is also important to maintain a proper balance of browns and greens in your compost bin. Paper is considered a carbon-rich or brown material, so ensure you have enough nitrogen-rich or green materials, such as kitchen scraps or fresh grass clippings, to create a balanced compost pile.
Can you compost cardboard?
Yes, cardboard can be composted. Cardboard is also made from plant fibers and can break down in a compost pile. However, similar to paper, there are restrictions on the type of cardboard that can be composted. Cardboard that is clean and free from any coatings or additives can be composted. On the other hand, cardboard that is waxed, laminated, or contains glossy print should not be composted.
Before adding cardboard to your compost bin, it is best to tear or cut it into small pieces, just like paper. This will help facilitate decomposition. As with paper, it is important to maintain a balanced compost pile by adding enough greens to the mix.
Restrictions on composting paper and cardboard
While paper and cardboard can generally be composted, there are some restrictions to keep in mind. Avoid composting paper or cardboard that has been contaminated with grease, oil, or any other non-compostable materials. These contaminants can hinder the decomposition process and introduce harmful substances into your compost. Ensure the paper or cardboard you are composting is free from tape, staples, or any other non-biodegradable attachments.
Additionally, if you are using compost from paper or cardboard that has been printed with colored ink, be cautious when using it on edible plants. Some inks may contain heavy metals or other substances that can be harmful if consumed. It is recommended to use compost from paper or cardboard with colored ink on non-edible plants or for soil amendment purposes only.
Conclusion
Paper and cardboard can be successfully composted as long as certain guidelines are followed. Both materials break down in the compost pile and contribute to the rich, nutrient-filled soil amendment known as humus. However, it is important to avoid composting glossy or coated paper and cardboard, as well as any materials that may contaminate the compost pile. By being mindful of these restrictions, you can compost paper and cardboard responsibly and contribute to a healthier environment.
