Arthur T Knackerbracket has found the following story:

Revolutionary 'green' types of bricks and construction materials could be made from recycled PVC, waste plant fibers or sand with the help of a remarkable new kind of rubber polymer discovered by Australian scientists.

The rubber polymer, itself made from sulfur and canola oil, can be compressed and heated with fillers to create construction materials of the future, says a new paper unveiling a promising new technique just published in Chemistry—A European Journal.

"This method could produce materials that may one day replace non-recyclable construction materials, bricks and even concrete replacement," says organic chemistry researcher Flinders University Associate Professor Justin Chalker.

[...] "This new recycling method and new composites are an important step forward in making sustainable construction materials, and the rubber material can be repeatedly ground up and recycled," says lead author Flinders Ph.D. Nic Lundquist. "The rubber particles also can be first used to purify water and then repurposed into a rubber mat or tubing."

"This is also important because there are currently few methods to recycle PVC or carbon fiber," he says, with collaborators from Flinders, Deakin University and University of WA.

[...] The new manufacturing and recycling technique, called reactive compression molding, applies to rubber material that can be compressed and stretched, but one that doesn't melt. The unique chemical structure of the sulfur backbone in the novel rubber allows for multiple pieces of the rubber to bond together.

    We also make bricks from clay.

    We also make bricks from mud.

    And hashish.
