This sandwich place by work has some compostable spoons, forks, knives.
They are about 6.5 inches long, and 6 grams each.
The handles have a long teardrop loop, convenient for a hook or for lighter weight.
On one side it has the brand name WORLDCENTRIC and the other side says: Compostable.
These seems reasonable durable, spoons for soups 200F, and the knife/fork good enough for a few meals. I've tried other lousy corn husk brand that break off in your food. These seem to be ok.
Found their website. Also interesting is the 30% talc. And 2 years if you stick it in your garden dirt.
6g (0.21 oz) not bad. In contrast the Light my Fire spork is .2 oz
I was thinking, on your last meal in the field, you can bury the utensil in the dirt or along with the poo, knowing that in 2 years or less it would biodegrade.
Utensils - 200F
Our new utensils are made from TPLA (70% non-GMO PLA and 30% talc.) They are also heat resistant up to 200 degrees F, and are certified under ASTM-6400 standards and now have BPI Certification.
World Centric TPLA utensils are compostable and biodegradable, and will take 120+ days to compost in a commercial composting facility. Home composting is not recommended and it may take 1-2 yrs to compost in a home composting system.
Most current utensils on the market made from plant starch are NOT compostable since current technology does not allow for manufacturing plant starch utensils without adding some plastic fillers. Since these plant starch utensils do not meet compostability standards they are normally priced cheaper.
