Biodegradable & compostable paper plates

Things that can be broken down into basic substances by normal environmental processes are said to be biodegradable. Animal and plant products are usually biodegradable, but minerals such as metallic glass and plastics usually are not.

Paper plate is a general term for a disposable pulp plate. In nature, paper plates can be made from a variety of raw materials, most of which are biodegradable, Such as sugarcane fiber, vegetable starch, wood fiber, bamboo fiber, palm leaves and so on.

However, the degree of decomposition and the time required for biodegradable plates vary widely. It depends on what other raw materials and additives the paper plate is doped with during the manufacturing process.

  • Uncoated 100% sugarcane paper plates usually degrade naturally completely within 90 days.
  • The corn starch plate with PLA membrane can only degrade naturally by 60% to 80%.

It must be mentioned here that biodegradable paper plate is not always compostable biodegradable. Biodegradable does not necessarily mean that it is compostable.

If the paper plate contains chemicals, this could contaminate your compost pile. We will mention this later.

1. The compostable waste is aerated by mechanical rotation;
2. Place the waste in the container and turn it over for a long time;
3. A network of pipes delivers air and water to the containers to create a moist environment to speed degradation.

Obviously, this requires a lot of manpower and resources.

Industrial composting is usually faster than home composting, but it relies on industrial equipment, which is not available in every region.

Their Differences

  1. Home compost only accepts truly 100% compostable products
  2. Industrial composting can compost many biodegradable materials
  3. Industrial composting usually takes less time
  4. Industrial composting relies on machines

Home composting is becoming more and more popular because it is more applicable and convenient and saves society resources.
