As cities, businesses and residents strive for zero waste, the use of compostable food service ware is increasing. Cedar Grove and the Compost Feedstock Testing Institute (CFTI) work to support these programs while maintaining a high standard of compost quality across 20 composting facilities throughout the U.S. To accomplish higher food waste diversion and minimize contamination in urban feed stocks, Cedar Grove and its affiliated partners provide a program of technical review and field testing of compostable products to determine their true feasibility as food related feed stock when shipped to fully permitted industrial composting facilities.
Items submitted for Cedar Grove and CFTI acceptance include bags, utensils, plates, bowls, clamshells, wraps and more. As new products are developed to meet growing market demands, Cedar Grove and CFTI provide the expertise to determine how well the products will break down in modern, large scale compost manufacturing technologies. For general questions about this, please contact: email@example.com or call 360-329-4281.
Requirements for Cedar Grove/CFTI Testing and Substrate Review
To submit items for Cedar Grove/CFTI testing and acceptance, please note the following requirements:
Other Technologies Available for Testing Trials (please visit composterapproved.com for updates on facilities and locations)
Testing trials occur every month and/or when enough samples are collected to constitute a testing round. Testing technologies in the cycle include:
(Note that Cedar Grove and the CFTI only offer testing in aerobic compost manufacturing facilities. Anaerobic digestion is a distinctively different and separate technology than composting, and CFTI does not offer testing in these types of units).
Include three (3) to five (5) samples for each item submitted per technology test and include a unique Identification Number written on at least one of the items. (EXAMPLE- if you are testing in ASP and WINDROW, send three (3) to five (5) samples for each technology to cover both tests (or 10 samples in total).
Compostable Food Service Products
A minimum fee will be charged for up to ten (10) food service items submitted for testing based on each testing technology.
Items Per Batch
|$3,750||Per Test batch|
Up to 10
Compostable Kitchen Bucket and Collection Container Liners
A minimum fee will be charged for up to three (3) compostable bag liner(s) submitted for testing.
*Items Per Batch
|$1,125||Per Test Batch|
Up to 3
*You may submit smallest to largest size, along with lowest and highest mil thickness to cover all sizes and thicknesses in your product line.
Paper and Wood Items Substrate Review
Please inquire for fees associated with food service items submitted for technical analysis only. This would include items such as wood stir sticks, paper napkins, unvarnished and uncoated paperboard, etc.
Prerequisites for Field Testing:
Category A: Items must meet requirements for ASTM D6400 or EN 13432 testing, including: bioplastics, co-polymers, PLA coated paperboard and paper, and other similar items
Fill out the attached profile for all groups of items submitted. Please print out profile and sign. Profiles can be sent via email in pdf file format to firstname.lastname@example.org. Include BPI certification or ASTM lab results on finished product. Note that ASTM lab results must include:
Category B: Items that meet requirements for ASTM D6868 testing: plastics used as coatings on compostable substrates and fibrous materials.
Include BPI certification or ASTM lab results on finished product (note that ASTM lab results must include:
Category C: Items that may not require ASTM testing (paper towels, napkins, wood, uncoated or clay coated paperboard, and other similar items that are not bioplastics, molded fiber, coated papers, or PLA/paperboard composites)
Fill out the attached profile for all groups of items submitted. Please print out profile and sign. Profiles can be sent via email in pdf file format to email@example.com.
Send MSDS on any inks, coatings, or treatments (Note: If MSDS reports show hazardous properties, also send FDA approval for direct food contact).
** After technical review, items may require field testing if information on product is not adequate to determine acceptability. A staff team member will contact you for testing authorization prior to submitting it for the next relevant testing round.
Other Testing and Technical Services:
Pre-ASTM Product Testing
If you have specific products currently pending ASTM results, our program offers expedited and concurrent field testing. If the product(s) meet the disintegration requirements at the end of the testing cycle, you may then submit ASTM results showing that you have met the additional compostability specifications. With confirmation of ASTM results and acceptable filed disintegration testing results, you will then receive an acceptance and inclusion on the Cedar Grove published list.
Cost: $4750.00 (up to 5 samples or prototypes; each addl., $795.00)
Note- All testing fees must be paid at time of sample submission.
Official confirmation/denial or acceptance
*** Product and Substrate Research Testing
Research testing is designed to test a variety of products or prototypes that may have slight differences in composition. You can run up to five different substrates, components or specific items and product prototypes per testing batch. If you have questions on research testing please contact firstname.lastname@example.org
Cost: $4995 (up to 5 samples or prototypes; each addl., $1350)
All documentation from these test results must accompany samples and/or be tied by unique Identification Number and submitted electronically.
