We appreciate your commitment to compost standards

For Compost Manufacturers

Compost collection and processing programs continue to grow across the U.S., while the challenge of keeping feedstocks clean remains an ongoing operational and financial burden to processing facilities.

CMA’s mission is to make compost manufacturing more sustainable by working proactively to field test and identify compostable products in real-world processing technologies, while also engaging the supply chain in collaboratively working to minimize other inbound contaminants.

Compost manufacturers have free access to field-tested product acceptance lists developed by over 20 facilities on a technology basis (windrow, ASP, mass bed, covered in-vessel ASP), as well as relevant information available that addresses consumer, stakeholder, and supply chain issues. 

Compost facilities in the U.S. play a vital role in supporting the need for processing capacity as businesses, college campuses, policymakers, and solid waste professionals push for more volume and greater diversity in feedstocks intended for compost facilities.

The current focus in many cities and towns is the inclusion of food scraps, compostable service ware, adding commercial food scrap collection, multi-family food scrap collection, closed system paper towel collection programs, along with many other emerging programs focused on minimizing landfill waste.

What CMA can do for Compost Facilities — at no cost to you!

CMA’s vision and goal are to work to improve the business model for compost facilities by lowering contamination and its associated costs while proactively field testing compostable foodservice items for their viability throughout the varying process technologies (windrow, aerated static piles, tunnel, in-vessel, mass bed, etc.)CMA is the composters’ no-cost resource working for you to address your customers’ questions.

CMA’s list of tested and approved products can be linked to your website for the appropriate processing technology used for your program. Here is an example of a list Accepted Compostables for Covered In-Vessel Aerated Static Pile.
CMA will provide a monthly link and story in its Contaminant of the Month, highlighting, at the consumer level, many misunderstandings about what can go into compost bins. For instance, not all paper is just paper. Many are treated or coated with grease resistors that inhibit microbes from adequately breaking down paper. For that reason, CMA reviews and/or field tests substrates to determine, with the information they are provided, what might be acceptable into commercial composting programs. Here is a link to items that have been cleared for composting under the CMA program for covered in-vessel systems.
By utilizing the CMA lists for your facility, you can provide the best acceptance criteria available for your program. Driven by the varying process technologies, a simple link on your site to the CMA process list can save hours in customer service time, and gives your recycling partners an efficient, high level of service at no cost. Or, send us your lists and we will provide the feedback to will need to ensure the right products are being sourced for your system and program.
