LANSING — Coal ash could be used in concrete, lime ash could be used for farming and copper sand could be made into shingles under legislation that would allow certain industries to sell byproducts that they now throw away. These byproducts can’t be used now because they are classified as hazardous materials that can potentially harm the environment. But recently introduced “beneficial reuse” legislation would provide parameters for testing their toxicity. If the byproducts passed the test, they could be sold and reused rather than sent to expensive landfills. The bills will be discussed in committee and possibly reported out on April 17.
