Green Purchasing – Sustainability
"Sustainability" is the ability of a production or harvesting process...
to continue indefinitely because its source is infinitely renewable. There is no legal definition of the terms sustainable, green, natural or renewable, so purchasers must use caution.
Because of the non-renewability of petroleum resources, many products purchased by municipalities are marketed as "bio-based." This is generally understood to mean commercial or industrial products in which more than 50% of the ingredients (other than water) are sourced from plant, animal, mineral, marine or forestry materials.
