Cleaning Up a Dirty Word

Entrepreneur BILL EASTER

Company X-MAT

In Orlando, of all places, at UCF’s business incubator, a small company has a plan to reimagine coal — America’s most abundant fossil fuel. It’s cheap, light and very much out of favor. “When people think of coal, they think of a four-letter word,” says Bill Easter.

Easter has an engineering company called Semplastics that makes plastic components used in semiconductor chip manufacturing. In 2013, it spawned X-Mat, an advanced materials division, based on a low-cost, inorganic resin-based technology. Two years later, scientists and engineers began experimenting with coal dust as a filler to lower cost and increase performance.

Easter knows coal. The Texas native spent part of his youth in coal-rich West Virginia.

In one formulation, X-Mat takes raw coal, pulverized to dust, and mixes it with proprietary resins. The resulting ceramic is non-toxic, light, strong and doesn’t burn. The company has seven patents and 15 pending.

It’s received $7.5 million in federal grants and contracts to develop coal and coal waste into usable materials such as batteries and — front and center now for Easter — as a building material.

Easter says coal-core composite tiles can transform the roofing industry. For strength, it beats concrete roof tiles as well as ones made from Vermont slate and Santa Fe red clay.

X-Mat has federal grants to develop bricks, blocks, facades and panels using its coal-resin technology and a grant to design a house built from the coal-derived materials. Easter is aiming for West Virginia. He has a grant to open a pilot manufacturing line there. “If I put a coal plant here, everyone would hate me,” Easter says, “Up there I’m a hero.”

Of course, today’s promising tech can be tomorrow’s bust. The state early this century saw itself as a coming player in semiconductors with a Cirent, later Agere, factory in Central Florida. The state provided millions in incentives. The factory wound up closed and torn down. Easter philosophizes, in an interview, on how to tell a visionary entrepreneur from a mistaken one. “The only way you can tell is to come back in five years,” he says.

Nonetheless, given that public policy shuns coal as a power source in the U.S. — FPL in June tore down its last coal power plant in Florida — X-Mat and Easter create hope for mining-state economies.

“As incongruous as it is, a Florida company is helping out with this,” Easter says. “It’s very strange in some ways.”

Big John, world’s largest triceratops, finds home at Glazer Children’s Museum
Big John, world’s largest triceratops, finds home at Glazer Children’s Museum

The 26-foot-long dinosaur made history when it was first discovered in South Dakota in 2014. And it made history again in 2021 when it fetched a record $7.7 million at an auction in Paris, the most ever paid for ancient bones that weren’t a T. rex. The winning bid came from Tampa entrepreneur Sidd Pagidipati, chairperson of Ayon Capitol and Better Health Group. He is lending Big John to the museum for the next three years.
