Dekiln and Johnson Tiles Partner to Scale Low-Carbon Ceramic Alternatives

Dekiln is moving its low-carbon composite material from the lab to industrial production through a strategic partnership with Johnson Tiles. The technology uses plant-derived binders and recycled mineral powders, such as gypsum plaster, to create tiles that do not require high-temperature firing or glazing. This process reduces embodied carbon by 94 percent compared to traditional ceramic tiles and consists of over 95 percent recycled content. The companies are currently exploring the establishment of a pilot demonstration plant in Stoke-on-Trent to accelerate commercial availability.

Cutting 94 percent of embodied carbon is a huge claim. The real test will be the durability and water absorption rates. If these are going into wet rooms or high traffic areas, they need to match ceramic performance or the replacement cycle will eat those carbon gains.

Agreed. From a policy side, this only scales if procurement rules for public buildings start mandating low embodied carbon materials. Without a carbon price or a strict building standard, the cost gap between these and cheap imports will be the main hurdle.

Interesting to see a move away from sintering. Most of the emissions in ceramics come from those kilns. Using plant binders and waste gypsum is a smart way to pivot. Just wondering how the supply chain for those specific binders holds up at scale.

The energy savings from skipping the firing process are the real win here. I want to see the actual energy intensity per square meter compared to a standard kiln. Is the pilot plant in Stoke-on-Trent actually funded or just a possibility?
