What to Compost and What Not to Compost

What to Compost or What Not to Compost

Composting is the all-natural process of recycling food and other organic waste into valuable soil-enriching fertilizer.

Anything and everything that grows eventually decomposes. Composting speeds that process up by providing an ideal environment for the decomposing organisms to grow and do their work.

The resultant “dark gold” is rich in nutrients and can be used for gardening, horticulture, and agriculture. Here is a guide on what to compost out of all the natural waste products around you.

Compost provides a range of environmental benefits, including improving soil health, reducing greenhouse gas emissions, recycling nutrients, and mitigating droughts’ impact.

This practice is like giving life to your soil, but composting is vital and beneficial even if one does not have a garden. Returning the organic waste to the earth ensures a mineral and nutrient cycle and balance, which is essential for our survival in this age of overconsumption and little conservation.

Moreover, composting is a great way to eliminate leftover food, plant material, and other biodegradable items that would otherwise have to be taken away to a landfill site or disposed of by refuse collectors.

 About twenty to fifty percent of your household waste stream can be taken care of via composting but knowing what can be safely thrown into the compost pit and what should stay out of it can be confusing.

When composting, it is essential to remember and maintain the proper balance of ingredients. Most composting experts advise a balance between green waste or watery materials like fruits and vegetables, grass clippings, and weeds and brown waste like dried leaves, sticks, fur, cloth, cardboard, and paper.

To help you get started with a compost heap and make this as easy as can be, we have prepared this list of more than forty things you can compost and the few things you should never add to your compost bin.

So, the next time you find yourself wondering what to compost and what not to compost, this article will be right here, waiting to be your guide as you continue to educate yourself and make this world a little greener and cleaner.
