Compostable, insulating, low-carbon and carbon-negative packaging containers
Sustainable plant-based containers that are compostable, insulating, strong, and carbon-negative. Validated for keeping hot foods hot, now expanding into cold-chain applications such as ice cream packaging. Backed by EPA, NSF, and USDA grants with active pilot programs.
Overview
Corumat offers compostable, insulating containers made from engineered plant-based materials that are strong, low-carbon, and carbon-negative. The containers have been validated for keeping hot foods at temperature and are now being explored for cold-chain applications such as ice cream and other frozen products. By replacing conventional petroleum-based plastics and expanded polystyrene foam, these containers help brands meet sustainability goals while maintaining the thermal performance needed to preserve product quality. The technology supports the company's broader Big Green Loop vision of converting food and organic waste back into compostable packaging.
Technical specifications
Key features:
- Compostable plant-based construction that reduces landfill and ocean plastic waste
- Insulating performance validated for hot food applications and under evaluation for cold-chain uses
- Strong, lightweight structure requiring significantly less material than traditional plastics
- Low-carbon and often carbon-negative footprint across the product lifecycle
- Patented micro-engineered manufacturing process enabling heat stability and durability
- Versatile format adaptable to food service packaging, insulated shipping, and building applications
Technology readiness level
The technology has progressed beyond laboratory validation into funded pilot deployments, supported by over $5 million in non-dilutive grant funding from the EPA, the National Science Foundation, and the USDA, alongside $700k in pilot revenue and $2.2M in investor funding. Next-stage validation activities include defining performance criteria for cold-chain applications, producing and evaluating prototypes, and scaling commercialization either through Corumat's own factory or with partner converters. A collaborative press launch is planned with public and industry partners to showcase adoption by major food brands.
About Corumat, Inc.
Corumat, Inc. is a materials science company founded in 2013 that specializes in micro-engineering sustainable, plant-based materials to replace conventional plastics. The company uses a patented manufacturing process to create lightweight, durable, and heat-stable structures that require significantly less material than traditional petroleum-based plastics. Its primary focus is on decarbonizing the packaging and waste industries through products that are compostable and often carbon-negative. The company's technology is versatile, with applications spanning food service packaging, sporting goods, transportation materials, and building insulation.
Corumat addresses critical environmental challenges by developing the Big Green Loop, an ecosystem designed to divert food and organic waste from landfills and convert them back into compostable packaging. This approach aims to reduce greenhouse gas emissions and combat ocean plastic pollution by creating profitable waste infrastructure. The company has demonstrated its technology through pilot programs and collaborations with research institutions, including the USDA. Corumat has successfully secured over $5 million in non-dilutive grant funding from organizations such as the EPA, the National Science Foundation, and the USDA to support its research, development, and scaling efforts.
