What type of binder is used to mould the bamboo and sugarcane together?
PLA is the binder.
Made from sugars found in certain plants (Corn, Sugarcane, Cassava). It’s dishwasher safe, but biodegradable by design (as it is made from plants).
10% bamboo fibre
Moderate heat tolerance – Product will lose strength and warp IF used in/on extremely hot foots.
PLA products don’t offer an ultra high heat tolerance – a trade-off of having a compostable design.
Knork have safety tested their Eco utensils up to 93 degrees centigrade, in a commercial dishwasher, but prolonged exposure at higher temperatures than that is not advised (such as dishwashers with a ‘heavy duty’ high heat cycle, using the utensils to stir or cut food directly out of a microwave or over).
However, just because a utensil becomes warped, it is not permanent. If you were to heat it up again, it would become pliable enough to bend back into its normal form.
