Announcing the Cradle to Cradle Innovation Prize Finalists

In November of last year, Cradle to Cradle (C2C) Institute and Make It Right announced the C2C Product Innovation Challenge. Our goal was to identify and reward highly creative and innovative products for healthy, sustainable, affordable housing.

Whether manufacturers were already in production or needed a boost to bring their ideas to the market, we wanted to encourage companies designing building products to improve human and environmental health.

144 applicants were screened by Cradle to Cradle certification experts, toxicologists from ToxServices, and building professionals from Make It Right. Judges selected 10 finalists who are now being considered for the $250,000 cash prize. Meet the finalists below!

Mushroom® Insulation

Mushroom® Insulation is a renewable, high-performance, and cost-effective replacement for plastic foams. Ecovative’s process combines agricultural byproducts with fungal mycelium, a natural, self-assembling binder, to literally grow structural rigid insulation. We grew a tiny house, and we see this as a proving ground for the $21B rigid board foam insulation market. Read more…

Softbatts Sheep’s Wool Insulation

Bellwether Materials
Softbatts insulation is made from sheep’s wool. It is safe for people, animals, and the environment. Very little energy is used in manufacturing. Installers don’t need to suit up. Wool is known for its ability to absorb pollutants in the air, making interior spaces healthier. If the building catches on fire, wool insulation is difficult to burn and will delay the ignition of surrounding materials. If the building is demolished, the wool can easily be pulled out and reused, repurposed or recycled. Read more…

GR Green Roofing and Siding

GR Green Building Products Inc
GR Green Building Products Inc (GR Green) has developed a breakthrough, patented process to produce the world’s first truly ecological synthetic roofing and siding products at extremely competitive prices. Made from waste limestone and recycled plastic—milk bottles and grocery bags—GR Green CedarTM and GR Green SlateTM look natural, cost less than the competition and can be completely recycled at the end of their 50+ years of use, making GR’s products not only ecological but sustainable. Read more…


StormWall Industries
StormWall is a structural wall, floor, and ceiling system with panels that supersede and replace the use of drywall. Based on the Composite Panel Associates Carbon Model, StormWall panels sequester more than 3X the CO2 emitted from the production process and supply chain. The StormWall panel is Classified E1 for indoor air quality with Formaldehyde content confirmed at <8.0mg/100g. Panels are painted in factory with VOC-free, GREENGUARD certified paint, further reducing formaldehyde emissions by 80-95%. Read more…

bioMASON biobrick

Traditional brick manufacturing utilizes a fuel firing process and is responsible for approximately 800m tons of CO2 emissions every year. bioMASON’s protected technology instead employs bacteria to produce a natural cement within a mix of aggregate. Inputs are globally abundant and may be extracted from waste streams. The cementation process is achieved in ambient temperatures. A hardened brick requires less than 5 days to form, and is comparable in cost and performance to traditional masonry.Read more…

Reinforced Wood Wool Cement Board

Dutch Design Initiative
Reinforced Wood Wool Cement Board is a versatile building material made from wood wool and cement. The wooden pole in the board results in a constructive element. It can be used for walls and roofs. Boards are fire-resistant, waterproof, rot-resistant, termite- and vermin-resistant, insulating, sound-absorbing, free of harmful emissions, and accept a wide range of finishes. Read more…

ROMA Domus Mineral Paints

Our Domus paints are excellent interior finish paints and primers for sheetrock, wood, plasters, and trim. They are derived from natural materials, washable (matte sheen and above), free of toxic chemicals, free of asthmagens, hypoallergenic, and permeable, prohibit bacteria that form mold, and absorb CO2 (so no Sick Building Syndrome). They are ideal for use in commercial and residential areas: offices, schools, medical facilities, and homes. Easy to apply—spray, roll, or brush. Read more…

Ecococon Straw Panels

Prefabricated load-bearing Straw Panels are made for cost-efficient and precise construction of super-insulated houses. The Ecococon modular building system is made from 99.4% rapidly renewable and mostly locally sourced materials (straw and wood). The panels have been successfully applied in several passive houses. The modularity, use of small-sized timber, and the homogeneous look of the straw surface set this product apart.Read more...


Haploblocks are prefabricated modular building enclosure components assembled and connected on site. All materials are biodegradable or recyclable. The manufacture and assembly is simple, requiring few tools, little energy, and no water. Haploblocks can be disassembled and used again in new construction. Regional manufacturing further reduces energy and environmental costs and promotes social discourse and economic justice. Read more…

ECOR® Universal Construction Panels

ECOR® Universal Construction Panels come in various shapes and sizes. Fabrication, shipping, handling, and assembly are all low-cost. Panels are lightweight, low volume and designed for anyone to assemble, easily. ECOR® is a sustainable material technology that utilizes a ubiquitous raw material, available worldwide: waste cellulose fiber. ECOR® manufacturing includes a closed loop water system with 99.5% reutilization. Read more…
