What Are Compostable Bags: Everything You Need To Know

You compost, right? It’s a great way to reduce your carbon footprint by not throwing away food scraps and other compostable materials. However, composting works better if you have the right compost bags on hand. These compost bags are designed with the environment in mind – they’re biodegradable, eco-friendly, and compostable! This guide will take you through compost bags and composting. 

What Are Compost Bags?

A compost bag is a type of bag designed to hold organic materials that are meant to be composted. Compost bags are typically made from materials that are biodegradable, such as paper or cornstarch-based plastics. These bags allow the organic materials to break down naturally without harming the environment. They also make it easy to collect and transport organic waste to a composting facility or compost bin. 

Types of Compost Bags

There are compostable bags made of cotton or other natural materials that you can reuse. Naturally compostable bags can be a bit more expensive, but they are more durable than compostable plastic bags.A biodegradable compostable bag is a compostable bag that breaks down quickly and easily in your home compost bin without any special disposal. This type of compostable bag may be better for smaller homes with limited yard space, while reducing landfill waste by using less plastic.You should consider this type of compost when dealing with large amounts of food scraps such as everyday kitchen waste, leftovers from cooking, vegetable peels, fruit peels, etc.Compost bags are also great for composting yard clippings, leaves, grass clippings, and other small plants.Compostable bags are a green, economical option that saves you money on trash cans as well as the cost of compostable plastic bags that can be used only once before being disposed of in landfill waste. 

What is Compost?

When it comes to home composters, worm farms, or industrial composting facilities, it’s important to understand what compost actually is. Compost is really just decomposed organic material. It could be anything from kitchen waste, plants, twigs, eggshells, coffee grounds, worms or leaves.Compost is used in the garden or in the soil to improve the quality of the soil, making it a better environment for planting and growing. Over time, compostable plastics are broken down by microbes or fungi in the environment. The time frame depends on several factors, such as humidity or temperature – both of which are tightly controlled for optimal decomposition in an industrial composting facility.When composted through biowaste collection, plastics can decompose more quickly. This is due to the microbe-rich environment in industrial compost that helps plastics break down faster. This includes four main components: organic matter, oxygen, bacteria and moisture. 

Composting Process

The size of the pile, the type of material, is also a key factor in the time it takes to break down the plastic. For large quantities of compostable material, industrial composting facilities are more efficient. Large amounts of waste in a home composter or worm farm will take longer to break down.Essentially, the steps of composting include:

  • Choose where to dispose of your compostable material, i.e. worm farm/home compost or industrial compost facility
  • The layers in the composter are to be alternated (different substances, layered)
  • Layer upon layer until the compost bucket is full
  • Maintain compost – home compost must be added and turned, while industrial compost is maintained with controls
  • harvest compost


What Materials Are Recommended for Composting?

This article lists many materials that are required and suitable for composting, but the focus is on organic materials and compostable plastics, including leaves, food scraps, and grass clippings.Some suitable materials to add to your home composter or industrial composting facility:

  • food waste, including vegetables or food scraps
  • coffee grounds or tea
  • bread, pasta or cereal
  • grass clippings, twigs or leaves
  • feces or dry cat or dog food
  • cardboard
  • Newspaper (black and white) or printer paper

All of these materials are ideal organic materials that can decompose in the right environment, such as a home compost, worm farm (excluding acids), or an industrial home composting facility.
