compostable bag

…

A compostable bag is a type of bag that can be decomposed in a composting environment.

In terms of materials

Usually made from natural materials such as plant starch (commonly corn starch, potato starch, etc.), cellulose, etc., or a mixture of these natural materials with biodegradable polyester, etc.

advantage

Environmental Protection: Under appropriate composting conditions, compostable bags can be decomposed by microorganisms into natural substances such as carbon dioxide, water, and biomass, without remaining in the environment for a long time like traditional plastic bags, reducing white pollution.

Resource recycling and utilization: The decomposed products can be used as fertilizers to return to the soil, which helps improve soil structure and fertility.

Usage scenarios

Home composting: suitable for storing kitchen waste, and then putting the bags containing kitchen waste together into the home composting bin for composting treatment.

Commercial composting facilities: Some farmers' markets, food processing enterprises, etc. use compostable bags to store perishable waste for transportation to commercial composting facilities for centralized processing.

matters needing attention

Composting conditions: Specific composting conditions are required for complete decomposition, such as appropriate temperature (usually around 50-60 degrees Celsius is ideal), humidity (usually maintained at around 50-60%), and microbial environment. If casually discarded in the natural environment, it may not decompose properly.

Certification Mark: To ensure the compostability of the product, it is best to choose bags with relevant certification marks, such as ASTM D6400 certification in the United States, EN 13432 certification in Europe, etc.
