Wheatware™ tested various thicknesses of test blocks. All Wheatware™ test blocks qualified for meeting ASTM D6400-04 (international composting 90 day biodegradation standard) up to 19mm (3/4" thickness) see picture at bottom. The full range of Wheatware™ Compostable products are all made from our exclusive Wheatware™ bioresin. Below are the pictured results of 60 days of biodegradation during this lab study. At 90 days, the disintegrated remainder was gone, and the resulting compost thereafter not only was safe for highly sensitive plant life, but accelerated plant life growth (see Summer Barley plant pictures- top row of 4 rows is using the Wheatware™ Compost).
IMPORTANT: The 90-day turnover, from solid to compost, allows composting facilities to be economically sustainable and a viable alternative to landfills.
3mm: Approx 1/8" thickness (cutlery and chopsticks)
