Nothing into Something

Dust. Powder. Scraps. Waste—it’s what we first see when we look at our factories, when we pull back the curtain and examine what materials are spent and left over in the manufacturing process. The Waste Lab is a place where we take another look at that dust and ask “What if?”

What if this waste, bound for the landfill, has hidden value we haven’t explored? What if it simply takes a new way of seeing to find value where now we see waste? What if a manufacturing company can be regenerative? The Waste Lab is where we ask “What if?” and experiment until we find answers; until we turn waste into something meaningful.


Waste Makes… Tile, Buttons and More



We’re taking industrial waste and creating high-end tiles for Ann Sacks, with some made from 100% waste materials. Using a collection of second-hand tools and equipment, our small but intrepid team volunteered their collective skills and knowledge to sort and test waste materials, to design and create tile forms and to craft dry-pressed tiles with exquisite glazes. 



Curiosity and imagination have already led us into uncharted waters, and we’re learning more about what’s possible every day. We’re thinking about rammed earth structures and how we could partner with architects and builders. We’re playing with the possibility of making garment buttons from foundry waste and sink scrubbers from coffee grounds. This is just the beginning. 



Dry cull is a by-product of the vitreous process. We put as much dry cull back into production as possible, but a percentage is not suitable for our vitreous china products. This dry clay material makes a great tile body.




Spent or “green” sand is a mix of clay, beach sand, corn cobs, coal and water. It is recycled again and again until the sand particles are too small for the molding process. We’re experimenting with spent sand in our clay bodies, concrete products and for rammed earth building materials.




Some enamel powder falls to the floor and becomes “dirty” during enameling, so we can’t reintroduce it into the process as pure enamel. Instead, we’re using it as a material in our glazes and experimenting to find new color effects.




Foundry dust is made up of fine particles of sand, coal, clay, grinding dust, rust, dirt and some blasted enamel. It is a by-product of nearly every step of cast-iron manufacturing. Foundry dust forms the basis of our clay tile bodies.

Frequently Asked Questions

What is the Kohler Waste Lab?

Kohler Waste Lab will create high-value products and services out of industrial wastes, serving as a catalyst for how Kohler understands the material resources used in our processes. 


What does Kohler do with the rest of its waste?

Kohler’s Environment Health and Safety group has participated in Beneficial Reuse Programs for decades, reducing and recycling waste where possible and making it available for use in roadbeds and other construction projects, and as a component in outdoor furniture, countertops and other composite products. What is left goes to Kohler owned and operated landfills.


Are products from the Waste Lab available for purchase?

Our first batch of tiles should be available for purchase from Ann Sacks in 2019. 


Can people tour the Waste Lab?

The Waste Lab is a new kind of factory where learning and collaboration is paramount. Each person brings their passions, skills and drive to make a difference in the world as we progress our understanding of what it means to be a manufacturer, and as we redefine business, production and craftsmanship. Tours will be offered selectively for those interested in partnering with Kohler or learning how to reuse their own industrial waste materials.


Does the Waste Lab partner with other manufacturers or artists?

The Waste Lab just opened in July and is just beginning to make connections with potential manufacturing and design partners. The team is tapping into the expertise of designers and operations associates from across Kohler and is looking to make connections beyond the Kohler walls. The Ann Sacks marketing and sales teams are actively consulting on tile patterns and designs that will appeal to the brand’s discerning customers and are working with the Waste Lab team to plan for a market launch in 2019.
