Compostable Plastic Helps Form Nutritional Closed Loop

Extensive research conducted by independent research institutions confirms Ecovio's strengths in food production, packaging and transportation, and waste collection, based on the material's certified biodegradability in industrial and domestic compost and soil.

Studies have shown that biodegradable bag reduces food waste, returns nutrients to the soil by producing larger volumes of compost, and avoids the accumulation of plastic in the soil.

Soil biodegradable mulch for sustainable agriculture

Farmers in many countries use PE mulch to increase crop yields. However, after harvesting, it is often impossible for farmers to fully collect these films, especially when they are only a few microns thin. Therefore, PE residues find their way into the soil and accumulate there because they do not break down.

Now, a study by the Federal Institute of Technology in Zurich, Switzerland, shows for the first time that soil microorganisms can use films made of plastic polybutylene adipate (PBAT) as food.

Microbes use carbon in polymers to generate energy and form biomass. A biodegradable bag supplier believes that this means that PBAT is biodegradable in the soil and does not stay there like PE does.

biodegradable bag M 2351 from BASF is a certified (EN 17033) soil biodegradable plastic for mulch, consisting of biodegradable copolyester Ecoflex (PBAT) and other biodegradable polymers made from renewable raw materials . The film made from biodegradable bag M 2351 can remain in the soil after harvesting, without the need for laborious removal and recycling.

Naturally occurring microorganisms in the soil, such as bacteria or fungi, recognize the structure of the biodegradable bag M2351 mulch as a food that can be metabolized. The final products remaining after microbial degradation are carbon dioxide, water and biomass.

Avoid food waste with smart packaging

Due to its breathability, fruit and vegetable bags made from biodegradable bag help food stay fresh longer. This is the result of a study by the University of Natural Resources and Applied Life Sciences in Vienna, Austria, which measured the shelf life of different types of fruits and vegetables stored in bags made of PE and biodegradable bag.

Fruit and vegetable bags made from biodegradable bag show better water vapour and oxygen transmission rates: this allows different fruits and vegetables to be maintained at optimal humidity and oxygen concentrations. A longer shelf life is achieved.

For example, tomatoes can be stored in biodegradable bag bags for up to 4 times longer than PE bags. In this way, smart packaging can reduce food waste. In addition, the fruit and vegetable bags made by biodegradable bag are not only carriers and storage bags, but also can be reused as organic garbage bags to improve the collection and recycling of food waste.

Compostable Garbage Bag

Transparent compostable bag collects more organic waste

The separate collection of organic waste is a prerequisite for nutrient recovery and is therefore a closed loop of nutrition. Some pilot projects, such as in Berlin and Bad Dürkheim, Germany, and in India and China, have shown that when consumers can easily use degradable plastic bags, they collect more organic waste.

Consumers also collect food waste that they would not normally collect, such as greasy liquid food waste. In addition, the number of non-compostable bags discarded in organic waste bins has also decreased significantly.

A compostable dual-use bag made of biodegradable bag can collect more kitchen waste in a clean, safe and easy way, without the moist feeling and unpleasant smell, because the compostable garbage bag is tear-resistant Crack and moisture resistance.

Under the conditions of an industrial compost plant, Ecovio can be completely biodegraded by microorganisms and their enzymes within a few weeks (as defined by EN 13432). Valuable compost can then be used to increase nutrient density in the soil, forming a closed loop of nutrients.
