A Guide to Understanding Degradable, Renewable, and Recyclable Plastic Bags

What are the unique advantages of renewable plastic bags compared to fossil-based plastic bags? How are recyclable and biodegradable plastic bags defined? What are the differences between biodegradable, renewable, and recyclable plastic bags? Today, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will provide you with a popular science article to explain these popular environmental terms one by one.

Renewable Plastic Bags VS Fossil-Based Plastic Bags

To understand what renewable plastic bags are, we first need to understand what renewable resources are.

Renewable resources refer to resources that can reproduce and grow under specific spatiotemporal conditions in nature, continuously regenerate to keep up with their consumption rate, constantly maintain or expand their reserves, and can be repeatedly used by humans. Forests, soil, grasslands, wetlands, solar energy, wind energy, hydropower, animals, plants, microorganisms, and various natural biocommunities all belong to renewable resources.

Renewable plastic bags are plastic bags made from materials produced using these renewable resources. Typically, these materials can be quickly manufactured or produced, or replaced or supplemented through biological and other natural processes to keep up with their usage rate. Wood, cardboard, paper, and pulp are widely used renewable materials. As long as effective sustainable forestry management is implemented, a continuous supply of wood can be ensured to support the normal operation of human society.

Fossil-based plastic bags refer to plastic bags made from materials derived from the earth's limited fossil resources. Petroleum, natural gas, coal, minerals, or organic fossil sediment layers all belong to fossil resources, which are non-renewable in the short term; production materials processed from these resources, such as glass, plastics, and metals, are fossil-based materials.

Recyclable Plastic Bags

Recyclable plastic bags, as the name suggests, refer to plastic bags made from materials that have recyclable value and can be recycled and reused. Commonly used recyclable materials in daily life include paper, cardboard, glass, plastic, and metal. Among them, paper and cardboard have the dual characteristics of renewable and recyclable materials.

Recyclable materials play a huge role in energy conservation and environmental protection. Data shows that: one ton of waste paper can produce 850 kilograms of recycled paper, saving 3 cubic meters of wood; discarded PET plastic bottles can also be recycled and processed into yarn, used as textile materials in furniture, automobiles, and other industries.

  Biodegradable Plastic Bags

Shunxingyuan Packaging Bag Collection Overview

In the recycling process, there are two common concepts: biodegradable and compostable.

Biodegradable plastic bags refer to substances that can be completely decomposed into natural components through biological methods. The EU standard defines biodegradable plastic bags as: Within 6 months, with the assistance of bacteria, fungi, or other simple organisms, 90% of biodegradable plastic bags can be finally decomposed into carbon dioxide, water, and minerals.

Compared to biodegradable, compostable is a higher standard: improving the efficiency of biodegradation by controlling humidity, temperature, and oxidation processes, and requiring the substance to be finally decomposed into completely non-toxic components. The whole process is harmless to the environment. Therefore, compostable plastic bags can certainly achieve biodegradation, but biodegradable plastic bags are not necessarily compostable.

Most industrial waste, including traditional plastic bags, takes a very long time to degrade under natural conditions, some taking hundreds or even thousands of years, causing great harm to the environment. Wood and paper are typical biodegradable plastic bag materials, and compared to traditional plastic bags, they are obviously more environmentally friendly.

According to incomplete statistics, more than 10 million takeaway orders are delivered nationwide every day, and a large number of plastic packaging products are used. Considering that a traditional plastic bag takes at least four hundred years to degrade, more and more consumers are calling for the replacement of traditional plastic packaging bags with renewable and biodegradable plastic bags.
