All mining exacts a price on the environment and the economy, and the cost of mining gypsum and then transporting it via ship or rail to drywall manufacturing plants is considerable.

Legislation in some jurisdictions mandates that sulphur dioxide be scrubbed from the emissions of fossil-fuel-powered plants. This has created an opportunity to reduce the costs of mining substantially through the creation of synthetic gypsum as a byproduct of the scrubbing process, and its use as a replacement for virgin gypsum in the manufacture of gypsum products.
