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.
