Once, I was asked those questions above by one of our clients who are buying our CPLA cutlery and selling it in the European market.

She asked: "Yewtree, we want to know, how does the CPLA cutlery decompose in nature? How long does it take to compost in nature? You know, I put it last year in a glass with water to see if the form changes in the water. One month passed and nothing happened. Maybe you can tell me how the CPLA fork or spoon gets decomposed?

It's interesting that I did the same in Feb. 2021 when I started to enter the business of biodegradable items like knives, forks and spoons in Suzhou Quanhua Biomaterial Co.,Ltd. You see, it's still here at the bottom of the bottle, and plants growing well too.

Actually, before answering this question, we’d have to know at 1st what does “compostable products” mean? Certified compostable products including CPLA tableware, in many cases, means they have passed a specific compost test, which is commonly known as the ASTM D6400 – Compostable Product Test.

It is to say that the compostable items must compost within a reasonable short period of time, for example, 84 days for industrial composting, i.e. breaking it into tiny pieces; and 180 days for complete mineralization in a properly managed commercial composting facility. 


Meanwhile, the degradation of compostable tableware needs to be carried out under specific conditions, such as appropriate temperature, humidity, bacterial environment, etc.

It does not occur in landfills or water naturally.

Therefore, you’d have to check locally if the industrial composting facility is available or not after using it.

An ideal alternative to traditional, petroleum-based plastic utensils, this knife is made of CPLA, a plant- and chalk-based plastic that's formed with renewable resources to minimize environmental impact upon disposal. It also meets the standards for compostability to ensure easy disposal at commercial composting facilities when your customers have finished using it. This CPLA is crystalized PLA, which is stronger and can withstand higher temperatures than standard PLA, resulting in a sturdier utensil.
