Geopolymer concrete

Geopolymer concrete is a concrete-like material that uses an alkali-activated aluminosilicate binder instead of ordinary portland cement as the main binder. It can use materials such as fly ash, slag, or metakaolin, but its performance and carbon benefits depend strongly on chemistry, activators, curing, supply chains, and standards.

Bioplastics

Bioplastics are plastics that are biobased, biodegradable, compostable, or some combination of those traits. They can reduce reliance on fossil feedstocks in some uses, but their environmental value depends on chemistry, sourcing, labeling, and end-of-life systems.
