When purchasing green chemicals, concentrated options are the more sustainable choice compared to ready-to-use products. With concentrated products, there is less transportation impacts on the environment. Since manufacturers aren’t shipping the water used to dilute the chemical, more products can be sent at once, minimizing the number of trucks on the road or trains on the rails. Fewer packaging materials are needed as well.

When diluting concentrated products, janitors are able to re-use spray bottles, but with ready-to-use products, the many empty containers are thrown away, contributing significant amounts of waste to landfills.
