The basics: Plastic laminate countertops consist of a wafer-thin finish adhered to a plywood or particleboard substrate. That thin finish is a high-pressure laminate (HPL); it’s made of three layers of material bonded together by high heat and pressure: a clear melamine top for protection, a decorative layer and a backing made of phenolic resin-coated kraft paper. Well-known laminate manufacturers include Formica, Wilsonart and Nevamar.
Concrete counters can be a terrific green choice if they are sourced locally or cast in place (transporting heavy slabs great distances consumes a lot of energy). Also, look for low-impact aggregates, such as increased coal fly ash, and recycled glass or paper.
